I guess the next thing + I get told is that the "..." ellipses in the examples don't compile + with their C compiler. + +3.48 Thu Oct 30 09:02:37 CET 2008 + - further optimise away the EPOLL_CTL_ADD/MOD combo in the epoll + backend by assuming the kernel event mask hasn't changed if + ADD fails with EEXIST. + - work around spurious event notification bugs in epoll by using + a 32-bit generation counter. recreate kernel state if we receive + spurious notifications or unwanted events. this is very costly, + but I didn't come up with this horrible design. + - use memset to initialise most arrays now and do away with the + init functions. + - expand time-out strategies into a "Be smart about timeouts" section. + - drop the "struct" from all ev_watcher declarations in the + documentation and did other clarifications (yeah, it was a mistake + to have a struct AND a function called ev_loop). + - fix a bug where ev_default would not initialise the default + loop again after it was destroyed with ev_default_destroy. + - rename syserr to ev_syserr to avoid name clashes when embedding, + do similar changes for event.c. + +3.45 Tue Oct 21 21:59:26 CEST 2008 + - disable inotify usage on linux <2.6.25, as it is broken + (reported by Yoann Vandoorselaere). + - ev_stat erroneously would try to add inotify watchers + even when inotify wasn't available (this should only + have a performance impact). + - ev_once now passes both timeout and io to the callback if both + occur concurrently, instead of giving timeouts precedence. + - disable EV_USE_INOTIFY when sys/inotify.h is too old. + +3.44 Mon Sep 29 05:18:39 CEST 2008 + - embed watchers now automatically invoke ev_loop_fork on the + embedded loop when the parent loop forks. + - new function: ev_now_update (loop). + - verify_watcher was not marked static. + - improve the "associating..." manpage section. + - documentation tweaks here and there. + +3.43 Sun Jul 6 05:34:41 CEST 2008 + - include more include files on windows to get struct _stati64 + (reported by Chris Hulbert, but doesn't quite fix his issue). + - add missing #include in ev.c on windows (reported by + Matt Tolton). + +3.42 Tue Jun 17 12:12:07 CEST 2008 + - work around yet another windows bug: FD_SET actually adds fd's + multiple times to the fd_*SET*, despite official MSN docs claiming + otherwise.

Yay. + + Some of the specialties of libev not commonly found elsewhere are: + + - extensive and detailed, readable documentation (not doxygen garbage). + - fully supports fork, can detect fork in various ways and automatically + re-arms kernel mechanisms that do not support fork. + - highly optimised select, poll, epoll, kqueue and event ports backends. + - filesystem object (path) watching (with optional linux inotify support). + - wallclock-based times (using absolute time, cron-like). + - relative timers/timeouts (handle time jumps). + - fast intra-thread communication between multiple + event loops (with optional fast linux eventfd backend). + - extremely easy to embed (fully documented, no dependencies, + autoconf supported but optional). + - very small codebase, no bloated library, simple code. + - fully extensible by being able to plug into the event loop, + integrate other event loops, integrate other event loop users. + - very little memory use (small watchers, small event loop data). + - optional C++ interface allowing method and function callbacks + at no extra memory or runtime overhead. + - optional Perl interface with similar characteristics (capable + of running Glib/Gtk2 on libev). + - support for other languages (multiple C++ interfaces, D, Ruby, + Python) available from third-parties. + + Examples of programs that embed libev: the EV perl module, node.js, + auditd, rxvt-unicode, gvpe (GNU Virtual Private Ethernet), the + Deliantra MMORPG server (http://www.deliantra.net/), Rubinius (a + next-generation Ruby VM), the Ebb web server, the Rev event toolkit. + + +CONTRIBUTORS + + libev was written and designed by Marc Lehmann and Emanuele Giaquinta. + + The following people sent in patches or made other noteworthy + contributions to the design (for minor patches, see the Changes + file.

If you just want to know the basics of libev, I suggest +reading \*(L"\s-1ANATOMY OF A WATCHER\*(R"\s0, then the \*(L"\s-1EXAMPLE PROGRAM\*(R"\s0 above and +look up the missing functions in \*(L"\s-1GLOBAL FUNCTIONS\*(R"\s0 and the \f(CW\*(C`ev_io\*(C'\fR and +\&\f(CW\*(C`ev_timer\*(C'\fR sections in \*(L"\s-1WATCHER TYPES\*(R"\s0. +.SH "ABOUT LIBEV" +.IX Header "ABOUT LIBEV" +Libev is an event loop: you register interest in certain events (such as a +file descriptor being readable or a timeout occurring), and it will manage +these event sources and provide your program with events. +.PP +To do this, it must take more or less complete control over your process +(or thread) by executing the \fIevent loop\fR handler, and will then +communicate events via a callback mechanism. +.PP +You register interest in certain events by registering so-called \fIevent +watchers\fR, which are relatively small C structures you initialise with the +details of the event, and then hand it over to libev by \fIstarting\fR the +watcher. +.SS "\s-1FEATURES\s0" +.IX Subsection "FEATURES" +Libev supports \f(CW\*(C`select\*(C'\fR, \f(CW\*(C`poll\*(C'\fR, the Linux-specific \f(CW\*(C`epoll\*(C'\fR, the +BSD-specific \f(CW\*(C`kqueue\*(C'\fR and the Solaris-specific event port mechanisms +for file descriptor events (\f(CW\*(C`ev_io\*(C'\fR), the Linux \f(CW\*(C`inotify\*(C'\fR interface +(for \f(CW\*(C`ev_stat\*(C'\fR), Linux eventfd/signalfd (for faster and cleaner +inter-thread wakeup (\f(CW\*(C`ev_async\*(C'\fR)/signal handling (\f(CW\*(C`ev_signal\*(C'\fR)) relative +timers (\f(CW\*(C`ev_timer\*(C'\fR), absolute timers with customised rescheduling +(\f(CW\*(C`ev_periodic\*(C'\fR), synchronous signals (\f(CW\*(C`ev_signal\*(C'\fR), process status +change events (\f(CW\*(C`ev_child\*(C'\fR), and event watchers dealing with the event +loop mechanism itself (\f(CW\*(C`ev_idle\*(C'\fR, \f(CW\*(C`ev_embed\*(C'\fR, \f(CW\*(C`ev_prepare\*(C'\fR and +\&\f(CW\*(C`ev_check\*(C'\fR watchers) as well as file watchers (\f(CW\*(C`ev_stat\*(C'\fR) and even +limited support for fork events (\f(CW\*(C`ev_fork\*(C'\fR). +.PP +It also is quite fast (see this +benchmark comparing it to libevent +for example). +.SS "\s-1CONVENTIONS\s0" +.IX Subsection "CONVENTIONS" +Libev is very configurable. In this manual the default (and most common) +configuration will be described, which supports multiple event loops. For +more info about various configuration options please have a look at +\&\fB\s-1EMBED\s0\fR section in this manual. If libev was configured without support +for multiple event loops, then all functions taking an initial argument of +name \f(CW\*(C`loop\*(C'\fR (which is always of type \f(CW\*(C`struct ev_loop *\*(C'\fR) will not have +this argument. +.SS "\s-1TIME REPRESENTATION\s0" +.IX Subsection "TIME REPRESENTATION" +Libev represents time as a single floating point number, representing +the (fractional) number of seconds since the (\s-1POSIX\s0) epoch (in practice +somewhere near the beginning of 1970, details are complicated, don't +ask). This type is called \f(CW\*(C`ev_tstamp\*(C'\fR, which is what you should use +too. It usually aliases to the \f(CW\*(C`double\*(C'\fR type in C. When you need to do +any calculations on it, you should treat it as some floating point value. +.PP +Unlike the name component \f(CW\*(C`stamp\*(C'\fR might indicate, it is also used for +time differences (e.g. delays) throughout libev. +.SH "ERROR HANDLING" +.IX Header "ERROR HANDLING" +Libev knows three classes of errors: operating system errors, usage errors +and internal errors (bugs). +.PP +When libev catches an operating system error it cannot handle (for example +a system call indicating a condition libev cannot fix), it calls the callback +set via \f(CW\*(C`ev_set_syserr_cb\*(C'\fR, which is supposed to fix the problem or +abort. The default is to print a diagnostic message and to call \f(CW\*(C`abort +()\*(C'\fR. +.PP +When libev detects a usage error such as a negative timer interval, then +it will print a diagnostic message and abort (via the \f(CW\*(C`assert\*(C'\fR mechanism, +so \f(CW\*(C`NDEBUG\*(C'\fR will disable this checking): these are programming errors in +the libev caller and need to be fixed there. +.PP +Libev also has a few internal error-checking \f(CW\*(C`assert\*(C'\fRions, and also has +extensive consistency checking code. These do not trigger under normal +circumstances, as they indicate either a bug in libev or worse. +.SH "GLOBAL FUNCTIONS" +.IX Header "GLOBAL FUNCTIONS" +These functions can be called anytime, even before initialising the +library in any way. +.IP "ev_tstamp ev_time ()" 4 +.IX Item "ev_tstamp ev_time ()" +Returns the current time as libev would use it. Please note that the +\&\f(CW\*(C`ev_now\*(C'\fR function is usually faster and also often returns the timestamp +you actually want to know.

Also, \f(CW\*(C`dup ()\*(C'\fR'ed +file descriptors might not work very well if you register events for both +file descriptors. +.Sp +Best performance from this backend is achieved by not unregistering all +watchers for a file descriptor until it has been closed, if possible, +i.e. keep at least one watcher active per fd at all times.

If it +is stopped, it can be freely accessed (e.g. by calling \f(CW\*(C`ev_TYPE_set\*(C'\fR), +but it is still property of the event loop at this time, so cannot be +moved, freed or reused. And if it is active the rules described in the +previous item still apply. +.Sp +It is also possible to feed an event on a watcher that is not active (e.g. +via \f(CW\*(C`ev_feed_event\*(C'\fR), in which case it becomes pending without being +active. +.IP "stopped" 4 +.IX Item "stopped" +A watcher can be stopped implicitly by libev (in which case it might still +be pending), or explicitly by calling its \f(CW\*(C`ev_TYPE_stop\*(C'\fR function. The +latter will clear any pending state the watcher might be in, regardless +of whether it was active or not, so stopping a watcher explicitly before +freeing it is often a good idea. +.Sp +While stopped (and not pending) the watcher is essentially in the +initialised state, that is, it can be reused, moved, modified in any way +you wish (but when you trash the memory block, you need to \f(CW\*(C`ev_TYPE_init\*(C'\fR +it again). +.SS "\s-1WATCHER PRIORITY MODELS\s0" +.IX Subsection "WATCHER PRIORITY MODELS" +Many event loops support \fIwatcher priorities\fR, which are usually small +integers that influence the ordering of event callback invocation +between watchers in some way, all else being equal. +.PP +In libev, Watcher priorities can be set using \f(CW\*(C`ev_set_priority\*(C'\fR. See its +description for the more technical details such as the actual priority +range. +.PP +There are two common ways how these these priorities are being interpreted +by event loops: +.PP +In the more common lock-out model, higher priorities \*(L"lock out\*(R" invocation +of lower priority watchers, which means as long as higher priority +watchers receive events, lower priority watchers are not being invoked. +.PP +The less common only-for-ordering model uses priorities solely to order +callback invocation within a single event loop iteration: Higher priority +watchers are invoked before lower priority ones, but they all get invoked +before polling for new events. +.PP +Libev uses the second (only-for-ordering) model for all its watchers +except for idle watchers (which use the lock-out model). +.PP +The rationale behind this is that implementing the lock-out model for +watchers is not well supported by most kernel interfaces, and most event +libraries will just poll for the same events again and again as long as +their callbacks have not been executed, which is very inefficient in the +common case of one high-priority watcher locking out a mass of lower +priority ones. +.PP +Static (ordering) priorities are most useful when you have two or more +watchers handling the same resource: a typical usage example is having an +\&\f(CW\*(C`ev_io\*(C'\fR watcher to receive data, and an associated \f(CW\*(C`ev_timer\*(C'\fR to handle +timeouts. Under load, data might be received while the program handles +other jobs, but since timers normally get invoked first, the timeout +handler will be executed before checking for data. In that case, giving +the timer a lower priority than the I/O watcher ensures that I/O will be +handled first even under adverse conditions (which is usually, but not +always, what you want). +.PP +Since idle watchers use the \*(L"lock-out\*(R" model, meaning that idle watchers +will only be executed when no same or higher priority watchers have +received events, they can be used to implement the \*(L"lock-out\*(R" model when +required. +.PP +For example, to emulate how many other event libraries handle priorities, +you can associate an \f(CW\*(C`ev_idle\*(C'\fR watcher to each such watcher, and in +the normal watcher callback, you just start the idle watcher. The real +processing is done in the idle watcher callback. This causes libev to +continuously poll and process kernel event data for the watcher, but when +the lock-out case is known to be rare (which in turn is rare :), this is +workable. +.PP +Usually, however, the lock-out model implemented that way will perform +miserably under the type of load it was designed to handle. In that case, +it might be preferable to stop the real watcher before starting the +idle watcher, so the kernel will not have to process the event in case +the actual processing will be delayed for considerable time. +.PP +Here is an example of an I/O watcher that should run at a strictly lower +priority than the default, and which should only process data when no +other events are pending: +.PP +.Vb 2 +\& ev_idle idle; // actual processing watcher +\& ev_io io; // actual event watcher +\& +\& static void +\& io_cb (EV_P_ ev_io *w, int revents) +\& { +\& // stop the I/O watcher, we received the event, but +\& // are not yet ready to handle it. +\& ev_io_stop (EV_A_ w); +\& +\& // start the idle watcher to handle the actual event. +\& // it will not be executed as long as other watchers +\& // with the default priority are receiving events. +\& ev_idle_start (EV_A_ &idle); +\& } +\& +\& static void +\& idle_cb (EV_P_ ev_idle *w, int revents) +\& { +\& // actual processing +\& read (STDIN_FILENO, ...); +\& +\& // have to start the I/O watcher again, as +\& // we have handled the event +\& ev_io_start (EV_P_ &io); +\& } +\& +\& // initialisation +\& ev_idle_init (&idle, idle_cb); +\& ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ); +\& ev_io_start (EV_DEFAULT_ &io); +.Ve +.PP +In the \*(L"real\*(R" world, it might also be beneficial to start a timer, so that +low-priority connections can not be locked out forever under load. This +enables your program to keep a lower latency for important connections +during short periods of high load, while not completely locking out less +important ones. +.SH "WATCHER TYPES" +.IX Header "WATCHER TYPES" +This section describes each watcher in detail, but will not repeat +information given in the last section. Any initialisation/set macros, +functions and members specific to the watcher type are explained. +.PP +Members are additionally marked with either \fI[read\-only]\fR, meaning that, +while the watcher is active, you can look at the member and expect some +sensible content, but you must not modify it (you can modify it while the +watcher is stopped to your hearts content), or \fI[read\-write]\fR, which +means you can expect it to have some sensible content while the watcher +is active, but you can also modify it. Modifying it may not do something +sensible or take immediate effect (or do anything at all), but libev will +not crash or malfunction in any way. +.ie n .SS """ev_io"" \- is this file descriptor readable or writable?" +.el .SS "\f(CWev_io\fP \- is this file descriptor readable or writable?" +.IX Subsection "ev_io - is this file descriptor readable or writable?" +I/O watchers check whether a file descriptor is readable or writable +in each iteration of the event loop, or, more precisely, when reading +would not block the process and writing would at least be able to write +some data. This behaviour is called level-triggering because you keep +receiving events as long as the condition persists. Remember you can stop +the watcher if you don't want to act on the event and neither want to +receive future events. +.PP +In general you can register as many read and/or write event watchers per +fd as you want (as long as you don't confuse yourself). Setting all file +descriptors to non-blocking mode is also usually a good idea (but not +required if you know what you are doing). +.PP +Another thing you have to watch out for is that it is quite easy to +receive \*(L"spurious\*(R" readiness notifications, that is, your callback might +be called with \f(CW\*(C`EV_READ\*(C'\fR but a subsequent \f(CW\*(C`read\*(C'\fR(2) will actually block +because there is no data. It is very easy to get into this situation even +with a relatively standard program structure. Thus it is best to always +use non-blocking I/O: An extra \f(CW\*(C`read\*(C'\fR(2) returning \f(CW\*(C`EAGAIN\*(C'\fR is far +preferable to a program hanging until some data arrives. +.PP +If you cannot run the fd in non-blocking mode (for example you should +not play around with an Xlib connection), then you have to separately +re-test whether a file descriptor is really ready with a known-to-be good +interface such as poll (fortunately in the case of Xlib, it already does +this on its own, so its quite safe to use). Some people additionally +use \f(CW\*(C`SIGALRM\*(C'\fR and an interval timer, just to be sure you won't block +indefinitely. +.PP +But really, best use non-blocking mode. +.PP +\fIThe special problem of disappearing file descriptors\fR +.IX Subsection "The special problem of disappearing file descriptors" +.PP +Some backends (e.g. kqueue, epoll) need to be told about closing a file +descriptor (either due to calling \f(CW\*(C`close\*(C'\fR explicitly or any other means, +such as \f(CW\*(C`dup2\*(C'\fR). The reason is that you register interest in some file +descriptor, but when it goes away, the operating system will silently drop +this interest. If another file descriptor with the same number then is +registered with libev, there is no efficient way to see that this is, in +fact, a different file descriptor. +.PP +To avoid having to explicitly tell libev about such cases, libev follows +the following policy: Each time \f(CW\*(C`ev_io_set\*(C'\fR is being called, libev +will assume that this is potentially a new file descriptor, otherwise +it is assumed that the file descriptor stays the same. That means that +you \fIhave\fR to call \f(CW\*(C`ev_io_set\*(C'\fR (or \f(CW\*(C`ev_io_init\*(C'\fR) when you change the +descriptor even if the file descriptor number itself did not change. +.PP +This is how one would do it normally anyway, the important point is that +the libev application should not optimise around libev but should leave +optimisations to libev. +.PP +\fIThe special problem of dup'ed file descriptors\fR +.IX Subsection "The special problem of dup'ed file descriptors" +.PP +Some backends (e.g. epoll), cannot register events for file descriptors, +but only events for the underlying file descriptions. That means when you +have \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors or weirder constellations, and register +events for them, only one file descriptor might actually receive events. +.PP +There is no workaround possible except not registering events +for potentially \f(CW\*(C`dup ()\*(C'\fR'ed file descriptors, or to resort to +\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR. +.PP +\fIThe special problem of files\fR +.IX Subsection "The special problem of files" +.PP +Many people try to use \f(CW\*(C`select\*(C'\fR (or libev) on file descriptors +representing files, and expect it to become ready when their program +doesn't block on disk accesses (which can take a long time on their own). +.PP +However, this cannot ever work in the \*(L"expected\*(R" way \- you get a readiness +notification as soon as the kernel knows whether and how much data is +there, and in the case of open files, that's always the case, so you +always get a readiness notification instantly, and your read (or possibly +write) will still block on the disk I/O. +.PP +Another way to view it is that in the case of sockets, pipes, character +devices and so on, there is another party (the sender) that delivers data +on its own, but in the case of files, there is no such thing: the disk +will not send data on its own, simply because it doesn't know what you +wish to read \- you would first have to request some data. +.PP +Since files are typically not-so-well supported by advanced notification +mechanism, libev tries hard to emulate \s-1POSIX\s0 behaviour with respect +to files, even though you should not use it. The reason for this is +convenience: sometimes you want to watch \s-1STDIN\s0 or \s-1STDOUT,\s0 which is +usually a tty, often a pipe, but also sometimes files or special devices +(for example, \f(CW\*(C`epoll\*(C'\fR on Linux works with \fI/dev/random\fR but not with +\&\fI/dev/urandom\fR), and even though the file might better be served with +asynchronous I/O instead of with non-blocking I/O, it is still useful when +it \*(L"just works\*(R" instead of freezing. +.PP +So avoid file descriptors pointing to files when you know it (e.g. use +libeio), but use them when it is convenient, e.g. for \s-1STDIN/STDOUT,\s0 or +when you rarely read from a file instead of from a socket, and want to +reuse the same code path. +.PP +\fIThe special problem of fork\fR +.IX Subsection "The special problem of fork" +.PP +Some backends (epoll, kqueue) do not support \f(CW\*(C`fork ()\*(C'\fR at all or exhibit +useless behaviour. Libev fully supports fork, but needs to be told about +it in the child if you want to continue to use it in the child. +.PP +To support fork in your child processes, you have to call \f(CW\*(C`ev_loop_fork +()\*(C'\fR after a fork in the child, enable \f(CW\*(C`EVFLAG_FORKCHECK\*(C'\fR, or resort to +\&\f(CW\*(C`EVBACKEND_SELECT\*(C'\fR or \f(CW\*(C`EVBACKEND_POLL\*(C'\fR. +.PP +\fIThe special problem of \s-1SIGPIPE\s0\fR +.IX Subsection "The special problem of SIGPIPE" +.PP +While not really specific to libev, it is easy to forget about \f(CW\*(C`SIGPIPE\*(C'\fR: +when writing to a pipe whose other end has been closed, your program gets +sent a \s-1SIGPIPE,\s0 which, by default, aborts your program. For most programs +this is sensible behaviour, for daemons, this is usually undesirable. +.PP +So when you encounter spurious, unexplained daemon exits, make sure you +ignore \s-1SIGPIPE \s0(and maybe make sure you log the exit status of your daemon +somewhere, as that would have given you a big clue). +.PP +\fIThe special problem of \fIaccept()\fIing when you can't\fR +.IX Subsection "The special problem of accept()ing when you can't" +.PP +Many implementations of the \s-1POSIX \s0\f(CW\*(C`accept\*(C'\fR function (for example, +found in post\-2004 Linux) have the peculiar behaviour of not removing a +connection from the pending queue in all error cases. +.PP +For example, larger servers often run out of file descriptors (because +of resource limits), causing \f(CW\*(C`accept\*(C'\fR to fail with \f(CW\*(C`ENFILE\*(C'\fR but not +rejecting the connection, leading to libev signalling readiness on +the next iteration again (the connection still exists after all), and +typically causing the program to loop at 100% \s-1CPU\s0 usage. +.PP +Unfortunately, the set of errors that cause this issue differs between +operating systems, there is usually little the app can do to remedy the +situation, and no known thread-safe method of removing the connection to +cope with overload is known (to me). +.PP +One of the easiest ways to handle this situation is to just ignore it +\&\- when the program encounters an overload, it will just loop until the +situation is over. While this is a form of busy waiting, no \s-1OS\s0 offers an +event-based way to handle this situation, so it's the best one can do. +.PP +A better way to handle the situation is to log any errors other than +\&\f(CW\*(C`EAGAIN\*(C'\fR and \f(CW\*(C`EWOULDBLOCK\*(C'\fR, making sure not to flood the log with such +messages, and continue as usual, which at least gives the user an idea of +what could be wrong (\*(L"raise the ulimit!\*(R"). For extra points one could stop +the \f(CW\*(C`ev_io\*(C'\fR watcher on the listening fd \*(L"for a while\*(R", which reduces \s-1CPU\s0 +usage. +.PP +If your program is single-threaded, then you could also keep a dummy file +descriptor for overload situations (e.g. by opening \fI/dev/null\fR), and +when you run into \f(CW\*(C`ENFILE\*(C'\fR or \f(CW\*(C`EMFILE\*(C'\fR, close it, run \f(CW\*(C`accept\*(C'\fR, +close that fd, and create a new dummy fd. This will gracefully refuse +clients under typical overload conditions. +.PP +The last way to handle it is to simply log the error and \f(CW\*(C`exit\*(C'\fR, as +is often done with \f(CW\*(C`malloc\*(C'\fR failures, but this results in an easy +opportunity for a DoS attack. +.PP +\fIWatcher-Specific Functions\fR +.IX Subsection "Watcher-Specific Functions" +.IP "ev_io_init (ev_io *, callback, int fd, int events)" 4 +.IX Item "ev_io_init (ev_io *, callback, int fd, int events)" +.PD 0 +.IP "ev_io_set (ev_io *, int fd, int events)" 4 +.IX Item "ev_io_set (ev_io *, int fd, int events)" +.PD +Configures an \f(CW\*(C`ev_io\*(C'\fR watcher.

Less obviously, it cannot be +guaranteed to any precision by libev \- imagine somebody suspending the +process with a \s-1STOP\s0 signal for a few hours for example. +.PP +So, libev tries to invoke your callback as soon as possible \fIafter\fR the +delay has occurred, but cannot guarantee this. +.PP +A less obvious failure mode is calling your callback too early: many event +loops compare timestamps with a \*(L"elapsed delay >= requested delay\*(R", but +this can cause your callback to be invoked much earlier than you would +expect. +.PP +To see why, imagine a system with a clock that only offers full second +resolution (think windows if you can't come up with a broken enough \s-1OS\s0 +yourself). If you schedule a one-second timer at the time 500.9, then the +event loop will schedule your timeout to elapse at a system time of 500 +(500.9 truncated to the resolution) + 1, or 501. +.PP +If an event library looks at the timeout 0.1s later, it will see \*(L"501 >= +501\*(R" and invoke the callback 0.1s after it was started, even though a +one-second delay was requested \- this is being \*(L"too early\*(R", despite best +intentions. +.PP +This is the reason why libev will never invoke the callback if the elapsed +delay equals the requested delay, but only when the elapsed delay is +larger than the requested delay. In the example above, libev would only invoke +the callback at system time 502, or 1.1s after the timer was started. +.PP +So, while libev cannot guarantee that your callback will be invoked +exactly when requested, it \fIcan\fR and \fIdoes\fR guarantee that the requested +delay has actually elapsed, or in other words, it always errs on the \*(L"too +late\*(R" side of things. +.PP +\fIThe special problem of time updates\fR +.IX Subsection "The special problem of time updates" +.PP +Establishing the current time is a costly operation (it usually takes +at least one system call): \s-1EV\s0 therefore updates its idea of the current +time only before and after \f(CW\*(C`ev_run\*(C'\fR collects new events, which causes a +growing difference between \f(CW\*(C`ev_now ()\*(C'\fR and \f(CW\*(C`ev_time ()\*(C'\fR when handling +lots of events in one iteration. +.PP +The relative timeouts are calculated relative to the \f(CW\*(C`ev_now ()\*(C'\fR +time. This is usually the right thing as this timestamp refers to the time +of the event triggering whatever timeout you are modifying/starting.

On a GNU/Linux system, for example, +a call to \f(CW\*(C`gettimeofday\*(C'\fR might return a second count that is one higher +than a directly following call to \f(CW\*(C`time\*(C'\fR. +.PP +The moral of this is to only compare libev-related timestamps with +\&\f(CW\*(C`ev_time ()\*(C'\fR and \f(CW\*(C`ev_now ()\*(C'\fR, at least if you want better precision than +a second or so. +.PP +One more problem arises due to this lack of synchronisation: if libev uses +the system monotonic clock and you compare timestamps from \f(CW\*(C`ev_time\*(C'\fR +or \f(CW\*(C`ev_now\*(C'\fR from when you started your timer and when your callback is +invoked, you will find that sometimes the callback is a bit \*(L"early\*(R". +.PP +This is because \f(CW\*(C`ev_timer\*(C'\fRs work in real time, not wall clock time, so +libev makes sure your callback is not invoked before the delay happened, +\&\fImeasured according to the real time\fR, not the system clock. +.PP +If your timeouts are based on a physical timescale (e.g. \*(L"time out this +connection after 100 seconds\*(R") then this shouldn't bother you as it is +exactly the right behaviour. +.PP +If you want to compare wall clock/system timestamps to your timers, then +you need to use \f(CW\*(C`ev_periodic\*(C'\fRs, as these are based on the wall clock +time, where your comparisons will always generate correct results. +.PP +\fIThe special problems of suspended animation\fR +.IX Subsection "The special problems of suspended animation" +.PP +When you leave the server world it is quite customary to hit machines that +can suspend/hibernate \- what happens to the clocks during such a suspend? +.PP +Some quick tests made with a Linux 2.6.28 indicate that a suspend freezes +all processes, while the clocks (\f(CW\*(C`times\*(C'\fR, \f(CW\*(C`CLOCK_MONOTONIC\*(C'\fR) continue +to run until the system is suspended, but they will not advance while the +system is suspended. That means, on resume, it will be as if the program +was frozen for a few seconds, but the suspend time will not be counted +towards \f(CW\*(C`ev_timer\*(C'\fR when a monotonic clock source is used. The real time +clock advanced as expected, but if it is used as sole clocksource, then a +long suspend would be detected as a time jump by libev, and timers would +be adjusted accordingly. +.PP +I would not be surprised to see different behaviour in different between +operating systems, \s-1OS\s0 versions or even different hardware. +.PP +The other form of suspend (job control, or sending a \s-1SIGSTOP\s0) will see a +time jump in the monotonic clocks and the realtime clock.

No, I don't know which ones, but there +are multiple ones to apply, and afterwards, event ports actually work +great. +.PP +If you can't get it to work, you can try running the program by setting +the environment variable \f(CW\*(C`LIBEV_FLAGS=3\*(C'\fR to only allow \f(CW\*(C`poll\*(C'\fR and +\&\f(CW\*(C`select\*(C'\fR backends. +.SS "\s-1AIX POLL BUG\s0" +.IX Subsection "AIX POLL BUG" +\&\s-1AIX\s0 unfortunately has a broken \f(CW\*(C`poll.h\*(C'\fR header. Libev works around +this by trying to avoid the poll backend altogether (i.e. it's not even +compiled in), which normally isn't a big problem as \f(CW\*(C`select\*(C'\fR works fine +with large bitsets on \s-1AIX,\s0 and \s-1AIX\s0 is dead anyway. +.SS "\s-1WIN32 PLATFORM LIMITATIONS AND WORKAROUNDS\s0" +.IX Subsection "WIN32 PLATFORM LIMITATIONS AND WORKAROUNDS" +\fIGeneral issues\fR +.IX Subsection "General issues" +.PP +Win32 doesn't support any of the standards (e.g. \s-1POSIX\s0) that libev +requires, and its I/O model is fundamentally incompatible with the \s-1POSIX\s0 +model. Libev still offers limited functionality on this platform in +the form of the \f(CW\*(C`EVBACKEND_SELECT\*(C'\fR backend, and only supports socket +descriptors. This only applies when using Win32 natively, not when using +e.g. cygwin. Actually, it only applies to the microsofts own compilers, +as every compiler comes with a slightly differently broken/incompatible +environment. +.PP +Lifting these limitations would basically require the full +re-implementation of the I/O system. If you are into this kind of thing, +then note that glib does exactly that for you in a very portable way (note +also that glib is the slowest event library known to man). +.PP +There is no supported compilation method available on windows except +embedding it into other applications. +.PP +Sensible signal handling is officially unsupported by Microsoft \- libev +tries its best, but under most conditions, signals will simply not work. +.PP +Not a libev limitation but worth mentioning: windows apparently doesn't +accept large writes: instead of resulting in a partial write, windows will +either accept everything or return \f(CW\*(C`ENOBUFS\*(C'\fR if the buffer is too large, +so make sure you only write small amounts into your sockets (less than a +megabyte seems safe, but this apparently depends on the amount of memory +available). +.PP +Due to the many, low, and arbitrary limits on the win32 platform and +the abysmal performance of winsockets, using a large number of sockets +is not recommended (and not reasonable). If your program needs to use +more than a hundred or so sockets, then likely it needs to use a totally +different implementation for windows, as libev offers the \s-1POSIX\s0 readiness +notification model, which cannot be implemented efficiently on windows +(due to Microsoft monopoly games). +.PP +A typical way to use libev under windows is to embed it (see the embedding +section for details) and use the following \fIevwrap.h\fR header file instead +of \fIev.h\fR: +.PP +.Vb 2 +\& #define EV_STANDALONE /* keeps ev from requiring config.h */ +\& #define EV_SELECT_IS_WINSOCKET 1 /* configure libev for windows select */ +\& +\& #include "ev.h" +.Ve +.PP +And compile the following \fIevwrap.c\fR file into your project (make sure +you do \fInot\fR compile the \fIev.c\fR or any other embedded source files!): +.PP +.Vb 2 +\& #include "evwrap.h" +\& #include "ev.c" +.Ve +.PP +\fIThe winsocket \f(CI\*(C`select\*(C'\fI function\fR +.IX Subsection "The winsocket select function" +.PP +The winsocket \f(CW\*(C`select\*(C'\fR function doesn't follow \s-1POSIX\s0 in that it +requires socket \fIhandles\fR and not socket \fIfile descriptors\fR (it is +also extremely buggy). This makes select very inefficient, and also +requires a mapping from file descriptors to socket handles (the Microsoft +C runtime provides the function \f(CW\*(C`_open_osfhandle\*(C'\fR for this). See the +discussion of the \f(CW\*(C`EV_SELECT_USE_FD_SET\*(C'\fR, \f(CW\*(C`EV_SELECT_IS_WINSOCKET\*(C'\fR and +\&\f(CW\*(C`EV_FD_TO_WIN32_HANDLE\*(C'\fR preprocessor symbols for more info. +.PP +The configuration for a \*(L"naked\*(R" win32 using the Microsoft runtime +libraries and raw winsocket select is: +.PP +.Vb 2 +\& #define EV_USE_SELECT 1 +\& #define EV_SELECT_IS_WINSOCKET 1 /* forces EV_SELECT_USE_FD_SET, too */ +.Ve +.PP +Note that winsockets handling of fd sets is O(n), so you can easily get a +complexity in the O(nX) range when using win32. +.PP +\fILimited number of file descriptors\fR +.IX Subsection "Limited number of file descriptors" +.PP +Windows has numerous arbitrary (and low) limits on things. +.PP +Early versions of winsocket's select only supported waiting for a maximum +of \f(CW64\fR handles (probably owning to the fact that all windows kernels +can only wait for \f(CW64\fR things at the same time internally; Microsoft +recommends spawning a chain of threads and wait for 63 handles and the +previous thread in each. Sounds great!). +.PP +Newer versions support more handles, but you need to define \f(CW\*(C`FD_SETSIZE\*(C'\fR +to some high number (e.g. \f(CW2048\fR) before compiling the winsocket select +call (which might be in libev or elsewhere, for example, perl and many +other interpreters do their own select emulation on windows). +.PP +Another limit is the number of file descriptors in the Microsoft runtime +libraries, which by default is \f(CW64\fR (there must be a hidden \fI64\fR +fetish or something like this inside Microsoft). You can increase this +by calling \f(CW\*(C`_setmaxstdio\*(C'\fR, which can increase this limit to \f(CW2048\fR +(another arbitrary limit), but is broken in many versions of the Microsoft +runtime libraries. This might get you to about \f(CW512\fR or \f(CW2048\fR sockets +(depending on windows version and/or the phase of the moon). To get more, +you need to wrap all I/O functions and provide your own fd management, but +the cost of calling select (O(nX)) will likely make this unworkable. +.SS "\s-1PORTABILITY REQUIREMENTS\s0" +.IX Subsection "PORTABILITY REQUIREMENTS" +In addition to a working ISO-C implementation and of course the +backend-specific APIs, libev relies on a few additional extensions: +.ie n .IP """void (*)(ev_watcher_type *, int revents)"" must have compatible calling conventions regardless of ""ev_watcher_type *""." 4 +.el .IP "\f(CWvoid (*)(ev_watcher_type *, int revents)\fR must have compatible calling conventions regardless of \f(CWev_watcher_type *\fR." 4 +.IX Item "void (*)(ev_watcher_type *, int revents) must have compatible calling conventions regardless of ev_watcher_type *." +Libev assumes not only that all watcher pointers have the same internal +structure (guaranteed by \s-1POSIX\s0 but not by \s-1ISO C\s0 for example), but it also +assumes that the same (machine) code can be used to call any watcher +callback: The watcher callbacks have different type signatures, but libev +calls them using an \f(CW\*(C`ev_watcher *\*(C'\fR internally. +.IP "null pointers and integer zero are represented by 0 bytes" 4 +.IX Item "null pointers and integer zero are represented by 0 bytes" +Libev uses \f(CW\*(C`memset\*(C'\fR to initialise structs and arrays to \f(CW0\fR bytes, and +relies on this setting pointers and integers to null. +.IP "pointer accesses must be thread-atomic" 4 +.IX Item "pointer accesses must be thread-atomic" +Accessing a pointer value must be atomic, it must both be readable and +writable in one piece \- this is the case on all current architectures. +.ie n .IP """sig_atomic_t volatile"" must be thread-atomic as well" 4 +.el .IP "\f(CWsig_atomic_t volatile\fR must be thread-atomic as well" 4 +.IX Item "sig_atomic_t volatile must be thread-atomic as well" +The type \f(CW\*(C`sig_atomic_t volatile\*(C'\fR (or whatever is defined as +\&\f(CW\*(C`EV_ATOMIC_T\*(C'\fR) must be atomic with respect to accesses from different +threads.

If you just want to know the basics of libev, I suggest +reading L, then the L above and +look up the missing functions in L and the C and +C sections in L. + +=head1 ABOUT LIBEV + +Libev is an event loop: you register interest in certain events (such as a +file descriptor being readable or a timeout occurring), and it will manage +these event sources and provide your program with events. + +To do this, it must take more or less complete control over your process +(or thread) by executing the I handler, and will then +communicate events via a callback mechanism. + +You register interest in certain events by registering so-called I, which are relatively small C structures you initialise with the +details of the event, and then hand it over to libev by I the +watcher. + +=head2 FEATURES + +Libev supports C (files, many character devices...). + +Epoll is truly the train wreck among event poll mechanisms, a frankenpoll, +cobbled together in a hurry, no thought to design or interaction with +others. Oh, the pain, will it ever stop... + +While stopping, setting and starting an I/O watcher in the same iteration +will result in some caching, there is still a system call per such +incident (because the same I could point to a different +I now), so its best to avoid that. Also, C'ed +file descriptors might not work very well if you register events for both +file descriptors. + +Best performance from this backend is achieved by not unregistering all +watchers for a file descriptor until it has been closed, if possible, +i.e. keep at least one watcher active per fd at all times. Stopping and +starting a watcher (without re-setting it) also usually doesn't cause +extra overhead. A fork can both result in spurious notifications as well +as in libev having to destroy and recreate the epoll object, which can +take considerable time and thus should be avoided. + +All this means that, in practice, C can be as fast or +faster than epoll for maybe up to a hundred file descriptors, depending on +the usage. So sad. + +While nominally embeddable in other event loops, this feature is broken in +all kernel versions tested so far. + +This backend maps C and C in the same way as +C. + +=item C (value 8, most BSD clones) + +Kqueue deserves special mention, as at the time of this writing, it +was broken on all BSDs except NetBSD (usually it doesn't work reliably +with anything but sockets and pipes, except on Darwin, where of course +it's completely useless). Unlike epoll, however, whose brokenness +is by design, these kqueue bugs can (and eventually will) be fixed +without API changes to existing programs. For this reason it's not being +"auto-detected" unless you explicitly specify it in the flags (i.e. using +C) or libev was compiled on a known-to-be-good (-enough) +system like NetBSD. + +You still can embed kqueue into a normal poll or select backend and use it +only for sockets (after having made sure that sockets work with kqueue on +the target platform). See C watchers for more info. + +It scales in the same way as the epoll backend, but the interface to the +kernel is more efficient (which says nothing about its actual speed, of +course). While stopping, setting and starting an I/O watcher does never +cause an extra system call as with C, it still adds up to +two event changes per incident. Support for C is very bad (you +might have to leak fd's on fork, but it's more sane than epoll) and it +drops fds silently in similarly hard-to-detect cases. + +This backend usually performs well under most conditions. + +While nominally embeddable in other event loops, this doesn't work +everywhere, so you might need to test for this. And since it is broken +almost everywhere, you should only use it when you have a lot of sockets +(for which it usually works), by embedding it into another event loop +(e.g. C or C (but C is of course +also broken on OS X)) and, did I mention it, using it only for sockets. + +This backend maps C into an C kevent with +C, and C into an C kevent with +C. + +=item C (value 16, Solaris 8) + +This is not implemented yet (and might never be, unless you send me an +implementation). According to reports, C only supports sockets +and is not embeddable, which would limit the usefulness of this backend +immensely. + +=item C (value 32, Solaris 10) + +This uses the Solaris 10 event port mechanism. As with everything on Solaris, +it's really slow, but it still scales very well (O(active_fds)). + +While this backend scales well, it requires one system call per active +file descriptor per loop iteration. For small and medium numbers of file +descriptors a "slow" C or C backend +might perform better. + +On the positive side, this backend actually performed fully to +specification in all tests and is fully embeddable, which is a rare feat +among the OS-specific backends (I vastly prefer correctness over speed +hacks). + +On the negative side, the interface is I - so bizarre that +even sun itself gets it wrong in their code examples: The event polling +function sometimes returns events to the caller even though an error +occurred, but with no indication whether it has done so or not (yes, it's +even documented that way) - deadly for edge-triggered interfaces where you +absolutely have to know whether an event occurred or not because you have +to re-arm the watcher. + +Fortunately libev seems to be able to work around these idiocies. + +This backend maps C and C in the same way as +C. + +=item C + +Try all backends (even potentially broken ones that wouldn't be tried +with C). Since this is a mask, you can do stuff such as +C. + +It is definitely not recommended to use this flag, use whatever +C returns, or simply do not specify a backend +at all. + +=item C + +Not a backend at all, but a mask to select all backend bits from a +C value, in case you want to mask out any backends from a flags +value (e.g. when modifying the C environment variable). + +=back + +If one or more of the backend flags are or'ed into the flags value, +then only these backends will be tried (in the reverse order as listed +here). If none are specified, all backends in C will be tried. + +Example: Try to create a event loop that uses epoll and nothing else. + + struct ev_loop *epoller = ev_loop_new (EVBACKEND_EPOLL | EVFLAG_NOENV); + if (!epoller) + fatal ("no epoll found here, maybe it hides under your chair"); + +Example: Use whatever libev has to offer, but make sure that kqueue is +used if available. + + struct ev_loop *loop = ev_loop_new (ev_recommended_backends () | EVBACKEND_KQUEUE); + +=item ev_loop_destroy (loop) + +Destroys an event loop object (frees all memory and kernel state +etc.). None of the active event watchers will be stopped in the normal +sense, so e.g. C might still return true. It is your +responsibility to either stop all watchers cleanly yourself I +calling this function, or cope with the fact afterwards (which is usually +the easiest thing, you can just ignore the watchers and/or C them +for example). + +Note that certain global state, such as signal state (and installed signal +handlers), will not be freed by this function, and related watchers (such +as signal and child watchers) would need to be stopped manually. + +This function is normally used on loop objects allocated by +C, but it can also be used on the default loop returned by +C, in which case it is not thread-safe. + +Note that it is not advisable to call this function on the default loop +except in the rare occasion where you really need to free its resources. +If you need dynamically allocated loops it is better to use C +and C. + +=item ev_loop_fork (loop) + +This function sets a flag that causes subsequent C iterations +to reinitialise the kernel state for backends that have one. Despite +the name, you can call it anytime you are allowed to start or stop +watchers (except inside an C callback), but it makes most +sense after forking, in the child process. You I call it (or use +C) in the child before resuming or calling C. + +In addition, if you want to reuse a loop (via this function or +C), you I have to ignore C. + +Again, you I to call it on I loop that you want to re-use after +a fork, I. This is +because some kernel interfaces *cough* I *cough* do funny things +during fork. + +On the other hand, you only need to call this function in the child +process if and only if you want to use the event loop in the child. If +you just fork+exec or create a new loop in the child, you don't have to +call it at all (in fact, C is so badly broken that it makes a +difference, but libev will usually detect this case on its own and do a +costly reset of the backend). + +The function itself is quite fast and it's usually not a problem to call +it just in case after a fork. + +Example: Automate calling C on the default loop when +using pthreads. + + static void + post_fork_child (void) + { + ev_loop_fork (EV_DEFAULT); + } + + ... + pthread_atfork (0, 0, post_fork_child); + +=item int ev_is_default_loop (loop) + +Returns true when the given loop is, in fact, the default loop, and false +otherwise. + +=item unsigned int ev_iteration (loop) + +Returns the current iteration count for the event loop, which is identical +to the number of times libev did poll for new events. It starts at C<0> +and happily wraps around with enough iterations. + +This value can sometimes be useful as a generation counter of sorts (it +"ticks" the number of loop iterations), as it roughly corresponds with +C and C calls - and is incremented between the +prepare and check phases. + +=item unsigned int ev_depth (loop) + +Returns the number of times C was entered minus the number of +times C was exited normally, in other words, the recursion depth. + +Outside C, this number is zero. In a callback, this number is +C<1>, unless C was invoked recursively (or from another thread), +in which case it is higher. + +Leaving C abnormally (setjmp/longjmp, cancelling the thread, +throwing an exception etc.), doesn't count as "exit" - consider this +as a hint to avoid such ungentleman-like behaviour unless it's really +convenient, in which case it is fully supported. + +=item unsigned int ev_backend (loop) + +Returns one of the C flags indicating the event backend in +use. + +=item ev_tstamp ev_now (loop) + +Returns the current "event loop time", which is the time the event loop +received events and started processing them. This timestamp does not +change as long as callbacks are being processed, and this is also the base +time used for relative timers. You can treat it as the timestamp of the +event occurring (or more correctly, libev finding out about it). + +=item ev_now_update (loop) + +Establishes the current time by querying the kernel, updating the time +returned by C in the progress. This is a costly operation and +is usually done automatically within C. + +This function is rarely useful, but when some event callback runs for a +very long time without entering the event loop, updating libev's idea of +the current time is a good idea. + +See also L in the C section. + +=item ev_suspend (loop) + +=item ev_resume (loop) + +These two functions suspend and resume an event loop, for use when the +loop is not used for a while and timeouts should not be processed. + +A typical use case would be an interactive program such as a game: When +the user presses C<^Z> to suspend the game and resumes it an hour later it +would be best to handle timeouts as if no time had actually passed while +the program was suspended. This can be achieved by calling C +in your C handler, sending yourself a C and calling +C directly afterwards to resume timer processing. + +Effectively, all C watchers will be delayed by the time spend +between C and C, and all C watchers +will be rescheduled (that is, they will lose any events that would have +occurred while suspended). + +After calling C you B call I function on the +given loop other than C, and you B call C +without a previous call to C. + +Calling C/C has the side effect of updating the +event loop time (see C). + +=item bool ev_run (loop, int flags) + +Finally, this is it, the event handler. This function usually is called +after you have initialised all your watchers and you want to start +handling events. It will ask the operating system for any new events, call +the watcher callbacks, and then repeat the whole process indefinitely: This +is why event loops are called I. + +If the flags argument is specified as C<0>, it will keep handling events +until either no event watchers are active anymore or C was +called. + +The return value is false if there are no more active watchers (which +usually means "all jobs done" or "deadlock"), and true in all other cases +(which usually means " you should call C again"). + +Please note that an explicit C is usually better than +relying on all watchers to be stopped when deciding when a program has +finished (especially in interactive programs), but having a program +that automatically loops as long as it has to and no longer by virtue +of relying on its watchers stopping correctly, that is truly a thing of +beauty. + +This function is I exception-safe - you can break out of a +C call by calling C in a callback, throwing a C++ +exception and so on. This does not decrement the C value, nor +will it clear any outstanding C breaks. + +A flags value of C will look for new events, will handle +those events and any already outstanding ones, but will not wait and +block your process in case there are no events and will return after one +iteration of the loop. This is sometimes useful to poll and handle new +events while doing lengthy calculations, to keep the program responsive. + +A flags value of C will look for new events (waiting if +necessary) and will handle those and any already outstanding ones. It +will block your process until at least one new event arrives (which could +be an event internal to libev itself, so there is no guarantee that a +user-registered callback will be called), and will return after one +iteration of the loop. + +This is useful if you are waiting for some external event in conjunction +with something not expressible using other libev watchers (i.e. "roll your +own C"). However, a pair of C/C watchers is +usually a better approach for this kind of thing. + +Here are the gory details of what C does (this is for your +understanding, not a guarantee that things will work exactly like this in +future versions): + + - Increment loop depth. + - Reset the ev_break status. + - Before the first iteration, call any pending watchers. + LOOP: + - If EVFLAG_FORKCHECK was used, check for a fork. + - If a fork was detected (by any means), queue and call all fork watchers. + - Queue and call all prepare watchers. + - If ev_break was called, goto FINISH. + - If we have been forked, detach and recreate the kernel state + as to not disturb the other process. + - Update the kernel state with all outstanding changes. + - Update the "event loop time" (ev_now ()). + - Calculate for how long to sleep or block, if at all + (active idle watchers, EVRUN_NOWAIT or not having + any active watchers at all will result in not sleeping). + - Sleep if the I/O and timer collect interval say so. + - Increment loop iteration counter. + - Block the process, waiting for any events. + - Queue all outstanding I/O (fd) events. + - Update the "event loop time" (ev_now ()), and do time jump adjustments. + - Queue all expired timers. + - Queue all expired periodics. + - Queue all idle watchers with priority higher than that of pending events. + - Queue all check watchers. + - Call all queued watchers in reverse order (i.e. check watchers first). + Signals and child watchers are implemented as I/O watchers, and will + be handled here by queueing them when their watcher gets executed. + - If ev_break has been called, or EVRUN_ONCE or EVRUN_NOWAIT + were used, or there are no active watchers, goto FINISH, otherwise + continue with step LOOP. + FINISH: + - Reset the ev_break status iff it was EVBREAK_ONE. + - Decrement the loop depth. + - Return. + +Example: Queue some jobs and then loop until no events are outstanding +anymore. + + ... queue jobs here, make sure they register event watchers as long + ... as they still have work to do (even an idle watcher will do..) + ev_run (my_loop, 0); + ... jobs done or somebody called break. yeah! + +=item ev_break (loop, how) + +Can be used to make a call to C return early (but only after it +has processed all outstanding events). The C argument must be either +C, which will make the innermost C call return, or +C, which will make all nested C calls return. + +This "break state" will be cleared on the next call to C. + +It is safe to call C from outside any C calls, too, in +which case it will have no effect. + +=item ev_ref (loop) + +=item ev_unref (loop) + +Ref/unref can be used to add or remove a reference count on the event +loop: Every watcher keeps one reference, and as long as the reference +count is nonzero, C will not return on its own. + +This is useful when you have a watcher that you never intend to +unregister, but that nevertheless should not keep C from +returning. In such a case, call C after starting, and C +before stopping it. + +As an example, libev itself uses this for its internal signal pipe: It +is not visible to the libev user and should not keep C from +exiting if no event watchers registered by it are active. It is also an +excellent way to do this for generic recurring timers or from within +third-party libraries. Just remember to I and I (but only if the watcher wasn't active before, or was active +before, respectively. Note also that libev might stop watchers itself +(e.g. non-repeating timers) in which case you have to C +in the callback). + +Example: Create a signal watcher, but keep it from keeping C +running when nothing else is active. + + ev_signal exitsig; + ev_signal_init (&exitsig, sig_cb, SIGINT); + ev_signal_start (loop, &exitsig); + ev_unref (loop); + +Example: For some weird reason, unregister the above signal handler again. + + ev_ref (loop); + ev_signal_stop (loop, &exitsig); + +=item ev_set_io_collect_interval (loop, ev_tstamp interval) + +=item ev_set_timeout_collect_interval (loop, ev_tstamp interval) + +These advanced functions influence the time that libev will spend waiting +for events. Both time intervals are by default C<0>, meaning that libev +will try to invoke timer/periodic callbacks and I/O callbacks with minimum +latency. + +Setting these to a higher value (the C I be >= C<0>) +allows libev to delay invocation of I/O and timer/periodic callbacks +to increase efficiency of loop iterations (or to increase power-saving +opportunities). + +The idea is that sometimes your program runs just fast enough to handle +one (or very few) event(s) per loop iteration. While this makes the +program responsive, it also wastes a lot of CPU time to poll for new +events, especially with backends like C (or libev) on file descriptors +representing files, and expect it to become ready when their program +doesn't block on disk accesses (which can take a long time on their own). + +However, this cannot ever work in the "expected" way - you get a readiness +notification as soon as the kernel knows whether and how much data is +there, and in the case of open files, that's always the case, so you +always get a readiness notification instantly, and your read (or possibly +write) will still block on the disk I/O. + +Another way to view it is that in the case of sockets, pipes, character +devices and so on, there is another party (the sender) that delivers data +on its own, but in the case of files, there is no such thing: the disk +will not send data on its own, simply because it doesn't know what you +wish to read - you would first have to request some data. + +Since files are typically not-so-well supported by advanced notification +mechanism, libev tries hard to emulate POSIX behaviour with respect +to files, even though you should not use it. The reason for this is +convenience: sometimes you want to watch STDIN or STDOUT, which is +usually a tty, often a pipe, but also sometimes files or special devices +(for example, C on Linux works with F but not with +F), and even though the file might better be served with +asynchronous I/O instead of with non-blocking I/O, it is still useful when +it "just works" instead of freezing. + +So avoid file descriptors pointing to files when you know it (e.g. use +libeio), but use them when it is convenient, e.g. for STDIN/STDOUT, or +when you rarely read from a file instead of from a socket, and want to +reuse the same code path. + +=head3 The special problem of fork + +Some backends (epoll, kqueue) do not support C at all or exhibit +useless behaviour. Libev fully supports fork, but needs to be told about +it in the child if you want to continue to use it in the child. + +To support fork in your child processes, you have to call C after a fork in the child, enable C, or resort to +C or C. + +=head3 The special problem of SIGPIPE + +While not really specific to libev, it is easy to forget about C: +when writing to a pipe whose other end has been closed, your program gets +sent a SIGPIPE, which, by default, aborts your program. For most programs +this is sensible behaviour, for daemons, this is usually undesirable. + +So when you encounter spurious, unexplained daemon exits, make sure you +ignore SIGPIPE (and maybe make sure you log the exit status of your daemon +somewhere, as that would have given you a big clue). + +=head3 The special problem of accept()ing when you can't + +Many implementations of the POSIX C function (for example, +found in post-2004 Linux) have the peculiar behaviour of not removing a +connection from the pending queue in all error cases. + +For example, larger servers often run out of file descriptors (because +of resource limits), causing C to fail with C but not +rejecting the connection, leading to libev signalling readiness on +the next iteration again (the connection still exists after all), and +typically causing the program to loop at 100% CPU usage. + +Unfortunately, the set of errors that cause this issue differs between +operating systems, there is usually little the app can do to remedy the +situation, and no known thread-safe method of removing the connection to +cope with overload is known (to me). + +One of the easiest ways to handle this situation is to just ignore it +- when the program encounters an overload, it will just loop until the +situation is over. While this is a form of busy waiting, no OS offers an +event-based way to handle this situation, so it's the best one can do. + +A better way to handle the situation is to log any errors other than +C and C, making sure not to flood the log with such +messages, and continue as usual, which at least gives the user an idea of +what could be wrong ("raise the ulimit!"). For extra points one could stop +the C watcher on the listening fd "for a while", which reduces CPU +usage. + +If your program is single-threaded, then you could also keep a dummy file +descriptor for overload situations (e.g. by opening F), and +when you run into C or C, close it, run C, +close that fd, and create a new dummy fd. This will gracefully refuse +clients under typical overload conditions. + +The last way to handle it is to simply log the error and C, as +is often done with C failures, but this results in an easy +opportunity for a DoS attack. + +=head3 Watcher-Specific Functions + +=over 4 + +=item ev_io_init (ev_io *, callback, int fd, int events) + +=item ev_io_set (ev_io *, int fd, int events) + +Configures an C watcher.

"Roughly" because +detecting time jumps is hard, and some inaccuracies are unavoidable (the +monotonic clock option helps a lot here). + +The callback is guaranteed to be invoked only I its timeout has +passed (not I, so on systems with very low-resolution clocks this +might introduce a small delay, see "the special problem of being too +early", below). If multiple timers become ready during the same loop +iteration then the ones with earlier time-out values are invoked before +ones of the same priority with later time-out values (but this is no +longer true when a callback calls C recursively). + +=head3 Be smart about timeouts + +Many real-world problems involve some kind of timeout, usually for error +recovery. A typical example is an HTTP request - if the other side hangs, +you want to raise some error after a while. + +What follows are some ways to handle this problem, from obvious and +inefficient to smart and efficient. + +In the following, a 60 second activity timeout is assumed - a timeout that +gets reset to 60 seconds each time there is activity (e.g. each time some +data or other life sign was received). + +=over 4 + +=item 1. Use a timer and stop, reinitialise and start it on activity. + +This is the most obvious, but not the most simple way: In the beginning, +start the watcher: + + ev_timer_init (timer, callback, 60., 0.); + ev_timer_start (loop, timer); + +Then, each time there is some activity, C it, initialise it +and start it again: + + ev_timer_stop (loop, timer); + ev_timer_set (timer, 60., 0.); + ev_timer_start (loop, timer); + +This is relatively simple to implement, but means that each time there is +some activity, libev will first have to remove the timer from its internal +data structure and then add it again. Libev tries to be fast, but it's +still not a constant-time operation. + +=item 2. Use a timer and re-start it with C inactivity. + +This is the easiest way, and involves using C instead of +C. + +To implement this, configure an C with a C value +of C<60> and then call C at start and each time you +successfully read or write some data. If you go into an idle state where +you do not expect data to travel on the socket, you can C +the timer, and C will automatically restart it if need be. + +That means you can ignore both the C function and the +C argument to C, and only ever use the C +member and C. + +At start: + + ev_init (timer, callback); + timer->repeat = 60.; + ev_timer_again (loop, timer); + +Each time there is some activity: + + ev_timer_again (loop, timer); + +It is even possible to change the time-out on the fly, regardless of +whether the watcher is active or not: + + timer->repeat = 30.; + ev_timer_again (loop, timer); + +This is slightly more efficient then stopping/starting the timer each time +you want to modify its timeout value, as libev does not have to completely +remove and re-insert the timer from/into its internal data structure. + +It is, however, even simpler than the "obvious" way to do it. + +=item 3. Let the timer time out, but then re-arm it as required. + +This method is more tricky, but usually most efficient: Most timeouts are +relatively long compared to the intervals between other activity - in +our example, within 60 seconds, there are usually many I/O events with +associated activity resets. + +In this case, it would be more efficient to leave the C alone, +but remember the time of last activity, and check for a real timeout only +within the callback: + + ev_tstamp timeout = 60.; + ev_tstamp last_activity; // time of last activity + ev_timer timer; + + static void + callback (EV_P_ ev_timer *w, int revents) + { + // calculate when the timeout would happen + ev_tstamp after = last_activity - ev_now (EV_A) + timeout; + + // if negative, it means we the timeout already occurred + if (after < 0.) + { + // timeout occurred, take action + } + else + { + // callback was invoked, but there was some recent + // activity. simply restart the timer to time out + // after "after" seconds, which is the earliest time + // the timeout can occur. + ev_timer_set (w, after, 0.); + ev_timer_start (EV_A_ w); + } + } + +To summarise the callback: first calculate in how many seconds the +timeout will occur (by calculating the absolute time when it would occur, +C, and subtracting the current time, C from that). + +If this value is negative, then we are already past the timeout, i.e. we +timed out, and need to do whatever is needed in this case. + +Otherwise, we now the earliest time at which the timeout would trigger, +and simply start the timer with this timeout value. + +In other words, each time the callback is invoked it will check whether +the timeout occurred. If not, it will simply reschedule itself to check +again at the earliest time it could time out. Rinse. Repeat. + +This scheme causes more callback invocations (about one every 60 seconds +minus half the average time between activity), but virtually no calls to +libev to change the timeout. + +To start the machinery, simply initialise the watcher and set +C to the current time (meaning there was some activity just +now), then call the callback, which will "do the right thing" and start +the timer: + + last_activity = ev_now (EV_A); + ev_init (&timer, callback); + callback (EV_A_ &timer, 0); + +When there is some activity, simply store the current time in +C, no libev calls at all: + + if (activity detected) + last_activity = ev_now (EV_A); + +When your timeout value changes, then the timeout can be changed by simply +providing a new value, stopping the timer and calling the callback, which +will again do the right thing (for example, time out immediately :). + + timeout = new_value; + ev_timer_stop (EV_A_ &timer); + callback (EV_A_ &timer, 0); + +This technique is slightly more complex, but in most cases where the +time-out is unlikely to be triggered, much more efficient. + +=item 4. Wee, just use a double-linked list for your timeouts. + +If there is not one request, but many thousands (millions...), all +employing some kind of timeout with the same timeout value, then one can +do even better: + +When starting the timeout, calculate the timeout value and put the timeout +at the I of the list. + +Then use an C to fire when the timeout at the I of +the list is expected to fire (for example, using the technique #3). + +When there is some activity, remove the timer from the list, recalculate +the timeout, append it to the end of the list again, and make sure to +update the C if it was taken from the beginning of the list. + +This way, one can manage an unlimited number of timeouts in O(1) time for +starting, stopping and updating the timers, at the expense of a major +complication, and having to use a constant timeout. The constant timeout +ensures that the list stays sorted. + +=back + +So which method the best? + +Method #2 is a simple no-brain-required solution that is adequate in most +situations. Method #3 requires a bit more thinking, but handles many cases +better, and isn't very complicated either. In most case, choosing either +one is fine, with #3 being better in typical situations. + +Method #1 is almost always a bad idea, and buys you nothing. Method #4 is +rather complicated, but extremely efficient, something that really pays +off after the first million or so of active timers, i.e. it's usually +overkill :) + +=head3 The special problem of being too early + +If you ask a timer to call your callback after three seconds, then +you expect it to be invoked after three seconds - but of course, this +cannot be guaranteed to infinite precision. Less obviously, it cannot be +guaranteed to any precision by libev - imagine somebody suspending the +process with a STOP signal for a few hours for example. + +So, libev tries to invoke your callback as soon as possible I the +delay has occurred, but cannot guarantee this. + +A less obvious failure mode is calling your callback too early: many event +loops compare timestamps with a "elapsed delay >= requested delay", but +this can cause your callback to be invoked much earlier than you would +expect. + +To see why, imagine a system with a clock that only offers full second +resolution (think windows if you can't come up with a broken enough OS +yourself). If you schedule a one-second timer at the time 500.9, then the +event loop will schedule your timeout to elapse at a system time of 500 +(500.9 truncated to the resolution) + 1, or 501. + +If an event library looks at the timeout 0.1s later, it will see "501 >= +501" and invoke the callback 0.1s after it was started, even though a +one-second delay was requested - this is being "too early", despite best +intentions. + +This is the reason why libev will never invoke the callback if the elapsed +delay equals the requested delay, but only when the elapsed delay is +larger than the requested delay. In the example above, libev would only invoke +the callback at system time 502, or 1.1s after the timer was started. + +So, while libev cannot guarantee that your callback will be invoked +exactly when requested, it I and I guarantee that the requested +delay has actually elapsed, or in other words, it always errs on the "too +late" side of things. + +=head3 The special problem of time updates + +Establishing the current time is a costly operation (it usually takes +at least one system call): EV therefore updates its idea of the current +time only before and after C collects new events, which causes a +growing difference between C and C when handling +lots of events in one iteration. + +The relative timeouts are calculated relative to the C +time. This is usually the right thing as this timestamp refers to the time +of the event triggering whatever timeout you are modifying/starting. If +you suspect event processing to be delayed and you I to base the +timeout on the current time, use something like the following to adjust +for it: + + ev_timer_set (&timer, after + (ev_time () - ev_now ()), 0.); + +If the event loop is suspended for a long time, you can also force an +update of the time returned by C by calling C, although that will push the event time of all outstanding events +further into the future. + +=head3 The special problem of unsynchronised clocks + +Modern systems have a variety of clocks - libev itself uses the normal +"wall clock" clock and, if available, the monotonic clock (to avoid time +jumps). + +Neither of these clocks is synchronised with each other or any other clock +on the system, so C might return a considerably different time +than C or C, below, for a more thorough treatment of -priorities. - -=item ev_invoke (loop, ev_TYPE *watcher, int revents) - -Invoke the C with the given C and C. Neither -C nor C need to be valid as long as the watcher callback -can deal with that fact, as both are simply passed through to the -callback. - -=item int ev_clear_pending (loop, ev_TYPE *watcher) - -If the watcher is pending, this function clears its pending status and -returns its C bitset (as if its callback was invoked). If the -watcher isn't pending it does nothing and returns C<0>. - -Sometimes it can be useful to "poll" a watcher instead of waiting for its -callback to be invoked, which can be accomplished with this function. - -=item ev_feed_event (loop, ev_TYPE *watcher, int revents) - -Feeds the given event set into the event loop, as if the specified event -had happened for the specified watcher (which must be a pointer to an -initialised but not necessarily started event watcher). Obviously you must -not free the watcher as long as it has pending events. - -Stopping the watcher, letting libev invoke it, or calling -C will clear the pending event, even if the watcher was -not started in the first place. - -See also C and C for related -functions that do not need a watcher. - -=back - -See also the L and L idioms. - -=head2 WATCHER STATES - -There are various watcher states mentioned throughout this manual - -active, pending and so on. In this section these states and the rules to -transition between them will be described in more detail - and while these -rules might look complicated, they usually do "the right thing". - -=over 4 - -=item initialised - -Before a watcher can be registered with the event loop it has to be -initialised. This can be done with a call to C, or calls to -C followed by the watcher-specific C function. - -In this state it is simply some block of memory that is suitable for -use in an event loop. It can be moved around, freed, reused etc. at -will - as long as you either keep the memory contents intact, or call -C again. - -=item started/running/active - -Once a watcher has been started with a call to C it becomes -property of the event loop, and is actively waiting for events. While in -this state it cannot be accessed (except in a few documented ways), moved, -freed or anything else - the only legal thing is to keep a pointer to it, -and call libev functions on it that are documented to work on active watchers. - -=item pending - -If a watcher is active and libev determines that an event it is interested -in has occurred (such as a timer expiring), it will become pending. It will -stay in this pending state until either it is stopped or its callback is -about to be invoked, so it is not normally pending inside the watcher -callback. - -The watcher might or might not be active while it is pending (for example, -an expired non-repeating timer can be pending but no longer active). If it -is stopped, it can be freely accessed (e.g. by calling C), -but it is still property of the event loop at this time, so cannot be -moved, freed or reused. And if it is active the rules described in the -previous item still apply. - -It is also possible to feed an event on a watcher that is not active (e.g. -via C), in which case it becomes pending without being -active. - -=item stopped - -A watcher can be stopped implicitly by libev (in which case it might still -be pending), or explicitly by calling its C function. The -latter will clear any pending state the watcher might be in, regardless -of whether it was active or not, so stopping a watcher explicitly before -freeing it is often a good idea. - -While stopped (and not pending) the watcher is essentially in the -initialised state, that is, it can be reused, moved, modified in any way -you wish (but when you trash the memory block, you need to C -it again). - -=back - -=head2 WATCHER PRIORITY MODELS - -Many event loops support I, which are usually small -integers that influence the ordering of event callback invocation -between watchers in some way, all else being equal. - -In libev, Watcher priorities can be set using C. See its -description for the more technical details such as the actual priority -range. - -There are two common ways how these these priorities are being interpreted -by event loops: - -In the more common lock-out model, higher priorities "lock out" invocation -of lower priority watchers, which means as long as higher priority -watchers receive events, lower priority watchers are not being invoked. - -The less common only-for-ordering model uses priorities solely to order -callback invocation within a single event loop iteration: Higher priority -watchers are invoked before lower priority ones, but they all get invoked -before polling for new events. - -Libev uses the second (only-for-ordering) model for all its watchers -except for idle watchers (which use the lock-out model). - -The rationale behind this is that implementing the lock-out model for -watchers is not well supported by most kernel interfaces, and most event -libraries will just poll for the same events again and again as long as -their callbacks have not been executed, which is very inefficient in the -common case of one high-priority watcher locking out a mass of lower -priority ones. - -Static (ordering) priorities are most useful when you have two or more -watchers handling the same resource: a typical usage example is having an -C watcher to receive data, and an associated C to handle -timeouts. Under load, data might be received while the program handles -other jobs, but since timers normally get invoked first, the timeout -handler will be executed before checking for data. In that case, giving -the timer a lower priority than the I/O watcher ensures that I/O will be -handled first even under adverse conditions (which is usually, but not -always, what you want). - -Since idle watchers use the "lock-out" model, meaning that idle watchers -will only be executed when no same or higher priority watchers have -received events, they can be used to implement the "lock-out" model when -required. - -For example, to emulate how many other event libraries handle priorities, -you can associate an C watcher to each such watcher, and in -the normal watcher callback, you just start the idle watcher. The real -processing is done in the idle watcher callback. This causes libev to -continuously poll and process kernel event data for the watcher, but when -the lock-out case is known to be rare (which in turn is rare :), this is -workable. - -Usually, however, the lock-out model implemented that way will perform -miserably under the type of load it was designed to handle. In that case, -it might be preferable to stop the real watcher before starting the -idle watcher, so the kernel will not have to process the event in case -the actual processing will be delayed for considerable time. - -Here is an example of an I/O watcher that should run at a strictly lower -priority than the default, and which should only process data when no -other events are pending: - - ev_idle idle; // actual processing watcher - ev_io io; // actual event watcher - - static void - io_cb (EV_P_ ev_io *w, int revents) - { - // stop the I/O watcher, we received the event, but - // are not yet ready to handle it. - ev_io_stop (EV_A_ w); - - // start the idle watcher to handle the actual event. - // it will not be executed as long as other watchers - // with the default priority are receiving events. - ev_idle_start (EV_A_ &idle); - } - - static void - idle_cb (EV_P_ ev_idle *w, int revents) - { - // actual processing - read (STDIN_FILENO, ...); - - // have to start the I/O watcher again, as - // we have handled the event - ev_io_start (EV_P_ &io); - } - - // initialisation - ev_idle_init (&idle, idle_cb); - ev_io_init (&io, io_cb, STDIN_FILENO, EV_READ); - ev_io_start (EV_DEFAULT_ &io); - -In the "real" world, it might also be beneficial to start a timer, so that -low-priority connections can not be locked out forever under load. This -enables your program to keep a lower latency for important connections -during short periods of high load, while not completely locking out less -important ones. - - -=head1 WATCHER TYPES - -This section describes each watcher in detail, but will not repeat -information given in the last section. Any initialisation/set macros, -functions and members specific to the watcher type are explained. - -Members are additionally marked with either I<[read-only]>, meaning that, -while the watcher is active, you can look at the member and expect some -sensible content, but you must not modify it (you can modify it while the -watcher is stopped to your hearts content), or I<[read-write]>, which -means you can expect it to have some sensible content while the watcher -is active, but you can also modify it. Modifying it may not do something -sensible or take immediate effect (or do anything at all), but libev will -not crash or malfunction in any way. - - -=head2 C - is this file descriptor readable or writable? - -I/O watchers check whether a file descriptor is readable or writable -in each iteration of the event loop, or, more precisely, when reading -would not block the process and writing would at least be able to write -some data. This behaviour is called level-triggering because you keep -receiving events as long as the condition persists. Remember you can stop -the watcher if you don't want to act on the event and neither want to -receive future events. - -In general you can register as many read and/or write event watchers per -fd as you want (as long as you don't confuse yourself). Setting all file -descriptors to non-blocking mode is also usually a good idea (but not -required if you know what you are doing). - -Another thing you have to watch out for is that it is quite easy to -receive "spurious" readiness notifications, that is, your callback might -be called with C but a subsequent C(2) will actually block -because there is no data. It is very easy to get into this situation even -with a relatively standard program structure. Thus it is best to always -use non-blocking I/O: An extra C(2) returning C is far -preferable to a program hanging until some data arrives. - -If you cannot run the fd in non-blocking mode (for example you should -not play around with an Xlib connection), then you have to separately -re-test whether a file descriptor is really ready with a known-to-be good -interface such as poll (fortunately in the case of Xlib, it already does -this on its own, so its quite safe to use). Some people additionally -use C and an interval timer, just to be sure you won't block -indefinitely. - -But really, best use non-blocking mode. - -=head3 The special problem of disappearing file descriptors - -Some backends (e.g. kqueue, epoll) need to be told about closing a file -descriptor (either due to calling C explicitly or any other means, -such as C). The reason is that you register interest in some file -descriptor, but when it goes away, the operating system will silently drop -this interest. If another file descriptor with the same number then is -registered with libev, there is no efficient way to see that this is, in -fact, a different file descriptor. - -To avoid having to explicitly tell libev about such cases, libev follows -the following policy: Each time C is being called, libev -will assume that this is potentially a new file descriptor, otherwise -it is assumed that the file descriptor stays the same. That means that -you I to call C (or C) when you change the -descriptor even if the file descriptor number itself did not change. - -This is how one would do it normally anyway, the important point is that -the libev application should not optimise around libev but should leave -optimisations to libev. - -=head3 The special problem of dup'ed file descriptors - -Some backends (e.g. epoll), cannot register events for file descriptors, -but only events for the underlying file descriptions. That means when you -have C'ed file descriptors or weirder constellations, and register -events for them, only one file descriptor might actually receive events. - -There is no workaround possible except not registering events -for potentially C'ed file descriptors, or to resort to -C or C. - -=head3 The special problem of files - -Many people try to use C. - -=item EV_USE_EVENTFD - -If defined to be C<1>, then libev will assume that C is -available and will probe for kernel support at runtime. This will improve -C and C performance and reduce resource consumption. -If undefined, it will be enabled if the headers indicate GNU/Linux + Glibc -2.7 or newer, otherwise disabled. - -=item EV_USE_SELECT - -If undefined or defined to be C<1>, libev will compile in support for the -C is buggy - -All that's left is C actively limits the number of file -descriptors you can pass in to 1024 - your program suddenly crashes when -you use more. - -There is an undocumented "workaround" for this - defining -C<_DARWIN_UNLIMITED_SELECT>, which libev tries to use, so select I -work on OS/X. - -=head2 SOLARIS PROBLEMS AND WORKAROUNDS - -=head3 C reentrancy - -The default compile environment on Solaris is unfortunately so -thread-unsafe that you can't even use components/libraries compiled -without C<-D_REENTRANT> in a threaded program, which, of course, isn't -defined by default. A valid, if stupid, implementation choice. - -If you want to use libev in threaded environments you have to make sure -it's compiled with C<_REENTRANT> defined. - -=head3 Event port backend - -The scalable event interface for Solaris is called "event -ports". Unfortunately, this mechanism is very buggy in all major -releases. If you run into high CPU usage, your program freezes or you get -a large number of spurious wakeups, make sure you have all the relevant -and latest kernel patches applied. No, I don't know which ones, but there -are multiple ones to apply, and afterwards, event ports actually work -great. - -If you can't get it to work, you can try running the program by setting -the environment variable C to only allow C and -C works fine -with large bitsets on AIX, and AIX is dead anyway. - -=head2 WIN32 PLATFORM LIMITATIONS AND WORKAROUNDS - -=head3 General issues - -Win32 doesn't support any of the standards (e.g. POSIX) that libev -requires, and its I/O model is fundamentally incompatible with the POSIX -model. Libev still offers limited functionality on this platform in -the form of the C backend, and only supports socket -descriptors. This only applies when using Win32 natively, not when using -e.g. cygwin. Actually, it only applies to the microsofts own compilers, -as every compiler comes with a slightly differently broken/incompatible -environment. - -Lifting these limitations would basically require the full -re-implementation of the I/O system. If you are into this kind of thing, -then note that glib does exactly that for you in a very portable way (note -also that glib is the slowest event library known to man). - -There is no supported compilation method available on windows except -embedding it into other applications. - -Sensible signal handling is officially unsupported by Microsoft - libev -tries its best, but under most conditions, signals will simply not work. - -Not a libev limitation but worth mentioning: windows apparently doesn't -accept large writes: instead of resulting in a partial write, windows will -either accept everything or return C if the buffer is too large, -so make sure you only write small amounts into your sockets (less than a -megabyte seems safe, but this apparently depends on the amount of memory -available). - -Due to the many, low, and arbitrary limits on the win32 platform and -the abysmal performance of winsockets, using a large number of sockets -is not recommended (and not reasonable). If your program needs to use -more than a hundred or so sockets, then likely it needs to use a totally -different implementation for windows, as libev offers the POSIX readiness -notification model, which cannot be implemented efficiently on windows -(due to Microsoft monopoly games). - -A typical way to use libev under windows is to embed it (see the embedding -section for details) and use the following F header file instead -of F: - - #define EV_STANDALONE /* keeps ev from requiring config.h */ - #define EV_SELECT_IS_WINSOCKET 1 /* configure libev for windows select */ - - #include "ev.h" - -And compile the following F file into your project (make sure -you do I compile the F or any other embedded source files!): - - #include "evwrap.h" - #include "ev.c" - -=head3 The winsocket C function doesn't follow POSIX in that it -requires socket I and not socket I (it is -also extremely buggy). This makes select very inefficient, and also -requires a mapping from file descriptors to socket handles (the Microsoft -C runtime provides the function C<_open_osfhandle> for this). See the -discussion of the C, C and -C preprocessor symbols for more info. - -The configuration for a "naked" win32 using the Microsoft runtime -libraries and raw winsocket select is: - - #define EV_USE_SELECT 1 - #define EV_SELECT_IS_WINSOCKET 1 /* forces EV_SELECT_USE_FD_SET, too */ - -Note that winsockets handling of fd sets is O(n), so you can easily get a -complexity in the O(n²) range when using win32. - -=head3 Limited number of file descriptors - -Windows has numerous arbitrary (and low) limits on things. - -Early versions of winsocket's select only supported waiting for a maximum -of C<64> handles (probably owning to the fact that all windows kernels -can only wait for C<64> things at the same time internally; Microsoft -recommends spawning a chain of threads and wait for 63 handles and the -previous thread in each. Sounds great!). - -Newer versions support more handles, but you need to define C -to some high number (e.g. C<2048>) before compiling the winsocket select -call (which might be in libev or elsewhere, for example, perl and many -other interpreters do their own select emulation on windows). - -Another limit is the number of file descriptors in the Microsoft runtime -libraries, which by default is C<64> (there must be a hidden I<64> -fetish or something like this inside Microsoft). You can increase this -by calling C<_setmaxstdio>, which can increase this limit to C<2048> -(another arbitrary limit), but is broken in many versions of the Microsoft -runtime libraries. This might get you to about C<512> or C<2048> sockets -(depending on windows version and/or the phase of the moon). To get more, -you need to wrap all I/O functions and provide your own fd management, but -the cost of calling select (O(n²)) will likely make this unworkable. - -=head2 PORTABILITY REQUIREMENTS - -In addition to a working ISO-C implementation and of course the -backend-specific APIs, libev relies on a few additional extensions: - -=over 4 - -=item C must have compatible -calling conventions regardless of C. - -Libev assumes not only that all watcher pointers have the same internal -structure (guaranteed by POSIX but not by ISO C for example), but it also -assumes that the same (machine) code can be used to call any watcher -callback: The watcher callbacks have different type signatures, but libev -calls them using an C internally. - -=item null pointers and integer zero are represented by 0 bytes - -Libev uses C to initialise structs and arrays to C<0> bytes, and -relies on this setting pointers and integers to null. - -=item pointer accesses must be thread-atomic - -Accessing a pointer value must be atomic, it must both be readable and -writable in one piece - this is the case on all current architectures. - -=item C must be thread-atomic as well - -The type C (or whatever is defined as -C) must be atomic with respect to accesses from different -threads. This is not part of the specification for C, but is -believed to be sufficiently portable. - -=item C must work in a threaded environment - -Libev uses C to temporarily block signals. This is not -allowed in a threaded program (C has to be used). Typical -pthread implementations will either allow C in the "main -thread" or will block signals process-wide, both behaviours would -be compatible with libev. Interaction between C and -C could complicate things, however. - -The most portable way to handle signals is to block signals in all threads -except the initial one, and run the signal handling loop in the initial -thread as well. - -=item C must be large enough for common memory allocation sizes - -To improve portability and simplify its API, libev uses C internally -instead of C when allocating its data structures. On non-POSIX -systems (Microsoft...) this might be unexpectedly low, but is still at -least 31 bits everywhere, which is enough for hundreds of millions of -watchers. - -=item C must hold a time value in seconds with enough accuracy - -The type C is used to represent timestamps. It is required to -have at least 51 bits of mantissa (and 9 bits of exponent), which is -good enough for at least into the year 4000 with millisecond accuracy -(the design goal for libev). This requirement is overfulfilled by -implementations using IEEE 754, which is basically all existing ones. - -With IEEE 754 doubles, you get microsecond accuracy until at least the -year 2255 (and millisecond accuracy till the year 287396 - by then, libev -is either obsolete or somebody patched it to use C or -something like that, just kidding). - -=back - -If you know of other additional requirements drop me a note. - - -=head1 ALGORITHMIC COMPLEXITIES - -In this section the complexities of (many of) the algorithms used inside -libev will be documented. For complexity discussions about backends see -the documentation for C. - -All of the following are about amortised time: If an array needs to be -extended, libev needs to realloc and move the whole array, but this -happens asymptotically rarer with higher number of elements, so O(1) might -mean that libev does a lengthy realloc operation in rare cases, but on -average it is much faster and asymptotically approaches constant time. - -=over 4 - -=item Starting and stopping timer/periodic watchers: O(log skipped_other_timers) - -This means that, when you have a watcher that triggers in one hour and -there are 100 watchers that would trigger before that, then inserting will -have to skip roughly seven (C) of these watchers. - -=item Changing timer/periodic watchers (by autorepeat or calling again): O(log skipped_other_timers) - -That means that changing a timer costs less than removing/adding them, -as only the relative motion in the event queue has to be paid for. - -=item Starting io/check/prepare/idle/signal/child/fork/async watchers: O(1) - -These just add the watcher into an array or at the head of a list. - -=item Stopping check/prepare/idle/fork/async watchers: O(1) - -=item Stopping an io/signal/child watcher: O(number_of_watchers_for_this_(fd/signal/pid % EV_PID_HASHSIZE)) - -These watchers are stored in lists, so they need to be walked to find the -correct watcher to remove. The lists are usually short (you don't usually -have many watchers waiting for the same fd or signal: one is typical, two -is rare). - -=item Finding the next timer in each loop iteration: O(1) - -By virtue of using a binary or 4-heap, the next timer is always found at a -fixed position in the storage array. - -=item Each change on a file descriptor per loop iteration: O(number_of_watchers_for_this_fd) - -A change means an I/O watcher gets started or stopped, which requires -libev to recalculate its status (and possibly tell the kernel, depending -on backend and whether C was used). - -=item Activating one watcher (putting it into the pending state): O(1) - -=item Priority handling: O(number_of_priorities) - -Priorities are implemented by allocating some space for each -priority. When doing priority-based operations, libev usually has to -linearly search all the priorities, but starting/stopping and activating -watchers becomes O(1) with respect to priority handling. - -=item Sending an ev_async: O(1) - -=item Processing ev_async_send: O(number_of_async_watchers) - -=item Processing signals: O(max_signal_number) - -Sending involves a system call I there were no other C -calls in the current loop iteration and the loop is currently -blocked. Checking for async and signal events involves iterating over all -running async watchers or all signal numbers. - -=back - - -=head1 PORTING FROM LIBEV 3.X TO 4.X - -The major version 4 introduced some incompatible changes to the API. - -At the moment, the C header file provides compatibility definitions -for all changes, so most programs should still compile. The compatibility -layer might be removed in later versions of libev, so better update to the -new API early than late. - -=over 4 - -=item C backwards compatibility mechanism - -The backward compatibility mechanism can be controlled by -C. See L in the L -section. - -=item C and C have been removed - -These calls can be replaced easily by their C counterparts: - - ev_loop_destroy (EV_DEFAULT_UC); - ev_loop_fork (EV_DEFAULT); - -=item function/symbol renames - -A number of functions and symbols have been renamed: - - ev_loop => ev_run - EVLOOP_NONBLOCK => EVRUN_NOWAIT - EVLOOP_ONESHOT => EVRUN_ONCE - - ev_unloop => ev_break - EVUNLOOP_CANCEL => EVBREAK_CANCEL - EVUNLOOP_ONE => EVBREAK_ONE - EVUNLOOP_ALL => EVBREAK_ALL - - EV_TIMEOUT => EV_TIMER - - ev_loop_count => ev_iteration - ev_loop_depth => ev_depth - ev_loop_verify => ev_verify - -Most functions working on C objects don't have an -C prefix, so it was removed; C, C and -associated constants have been renamed to not collide with the C anymore and C now follows the same naming scheme -as all other watcher types. Note that C is still called -C because it would otherwise clash with the C -typedef. - -=item C mechanism replaced by C - -The preprocessor symbol C has been replaced by a different -mechanism, C. Programs using C usually compile -and work, but the library code will of course be larger. - -=back - - -=head1 GLOSSARY - -=over 4 - -=item active - -A watcher is active as long as it has been started and not yet stopped. -See L for details. - -=item application - -In this document, an application is whatever is using libev. - -=item backend - -The part of the code dealing with the operating system interfaces. - -=item callback - -The address of a function that is called when some event has been -detected. Callbacks are being passed the event loop, the watcher that -received the event, and the actual event bitset. - -=item callback/watcher invocation - -The act of calling the callback associated with a watcher. - -=item event - -A change of state of some external event, such as data now being available -for reading on a file descriptor, time having passed or simply not having -any other events happening anymore. - -In libev, events are represented as single bits (such as C or -C). - -=item event library - -A software package implementing an event model and loop. - -=item event loop - -An entity that handles and processes external events and converts them -into callback invocations. - -=item event model - -The model used to describe how an event loop handles and processes -watchers and events. - -=item pending - -A watcher is pending as soon as the corresponding event has been -detected.

This file is offered as-is, -without warranty of any kind. - -Basic Installation -================== - - Briefly, the shell commands `./configure; make; make install' should -configure, build, and install this package. The following -more-detailed instructions are generic; see the `README' file for -instructions specific to this package. Some packages provide this -`INSTALL' file but do not implement all of the features documented -below. The lack of an optional feature in a given package is not -necessarily a bug. More recommendations for GNU packages can be found -in *note Makefile Conventions: (standards)Makefile Conventions. - - The `configure' shell script attempts to guess correct values for -various system-dependent variables used during compilation. It uses -those values to create a `Makefile' in each directory of the package. -It may also create one or more `.h' files containing system-dependent -definitions. Finally, it creates a shell script `config.status' that -you can run in the future to recreate the current configuration, and a -file `config.log' containing compiler output (useful mainly for -debugging `configure'). - - It can also use an optional file (typically called `config.cache' -and enabled with `--cache-file=config.cache' or simply `-C') that saves -the results of its tests to speed up reconfiguring. Caching is -disabled by default to prevent problems with accidental use of stale -cache files. - - If you need to do unusual things to compile the package, please try -to figure out how `configure' could check whether to do them, and mail -diffs or instructions to the address given in the `README' so they can -be considered for the next release. If you are using the cache, and at -some point `config.cache' contains results you don't want to keep, you -may remove or edit it. - - The file `configure.ac' (or `configure.in') is used to create -`configure' by a program called `autoconf'. You need `configure.ac' if -you want to change it or regenerate `configure' using a newer version -of `autoconf'. - - The simplest way to compile this package is: - - 1. `cd' to the directory containing the package's source code and type - `./configure' to configure the package for your system. - - Running `configure' might take a while. While running, it prints - some messages telling which features it is checking for. - - 2. Type `make' to compile the package. - - 3. Optionally, type `make check' to run any self-tests that come with - the package, generally using the just-built uninstalled binaries. - - 4. Type `make install' to install the programs and any data files and - documentation. When installing into a prefix owned by root, it is - recommended that the package be configured and built as a regular - user, and only the `make install' phase executed with root - privileges. - - 5. Optionally, type `make installcheck' to repeat any self-tests, but - this time using the binaries in their final installed location. - This target does not install anything. Running this target as a - regular user, particularly if the prior `make install' required - root privileges, verifies that the installation completed - correctly. - - 6. You can remove the program binaries and object files from the - source code directory by typing `make clean'. To also remove the - files that `configure' created (so you can compile the package for - a different kind of computer), type `make distclean'. There is - also a `make maintainer-clean' target, but that is intended mainly - for the package's developers. If you use it, you may have to get - all sorts of other programs in order to regenerate files that came - with the distribution. - - 7. Often, you can also type `make uninstall' to remove the installed - files again. In practice, not all packages have tested that - uninstallation works correctly, even though it is required by the - GNU Coding Standards. - - 8. Some packages, particularly those that use Automake, provide `make - distcheck', which can by used by developers to test that all other - targets like `make install' and `make uninstall' work correctly. - This target is generally not run by end users. - -Compilers and Options -===================== - - Some systems require unusual options for compilation or linking that -the `configure' script does not know about. Run `./configure --help' -for details on some of the pertinent environment variables. - - You can give `configure' initial values for configuration parameters -by setting variables in the command line or in the environment. Here -is an example: - - ./configure CC=c99 CFLAGS=-g LIBS=-lposix - - *Note Defining Variables::, for more details. - -Compiling For Multiple Architectures -==================================== - - You can compile the package for more than one kind of computer at the -same time, by placing the object files for each architecture in their -own directory. To do this, you can use GNU `make'. `cd' to the -directory where you want the object files and executables to go and run -the `configure' script. `configure' automatically checks for the -source code in the directory that `configure' is in and in `..'. This -is known as a "VPATH" build. - - With a non-GNU `make', it is safer to compile the package for one -architecture at a time in the source code directory. After you have -installed the package for one architecture, use `make distclean' before -reconfiguring for another architecture. - - On MacOS X 10.5 and later systems, you can create libraries and -executables that work on multiple system types--known as "fat" or -"universal" binaries--by specifying multiple `-arch' options to the -compiler but only a single `-arch' option to the preprocessor. Like -this: - - ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ - CPP="gcc -E" CXXCPP="g++ -E" - - This is not guaranteed to produce working output in all cases, you -may have to build one architecture at a time and combine the results -using the `lipo' tool if you have problems. - -Installation Names -================== - - By default, `make install' installs the package's commands under -`/usr/local/bin', include files under `/usr/local/include', etc. You -can specify an installation prefix other than `/usr/local' by giving -`configure' the option `--prefix=PREFIX', where PREFIX must be an -absolute file name. - - You can specify separate installation prefixes for -architecture-specific files and architecture-independent files. If you -pass the option `--exec-prefix=PREFIX' to `configure', the package uses -PREFIX as the prefix for installing programs and libraries. -Documentation and other data files still use the regular prefix. - - In addition, if you use an unusual directory layout you can give -options like `--bindir=DIR' to specify different values for particular -kinds of files. Run `configure --help' for a list of the directories -you can set and what kinds of files go in them. In general, the -default for these options is expressed in terms of `${prefix}', so that -specifying just `--prefix' will affect all of the other directory -specifications that were not explicitly provided. - - The most portable way to affect installation locations is to pass the -correct locations to `configure'; however, many packages provide one or -both of the following shortcuts of passing variable assignments to the -`make install' command line to change installation locations without -having to reconfigure or recompile. - - The first method involves providing an override variable for each -affected directory. For example, `make install -prefix=/alternate/directory' will choose an alternate location for all -directory configuration variables that were expressed in terms of -`${prefix}'. Any directories that were specified during `configure', -but not in terms of `${prefix}', must each be overridden at install -time for the entire installation to be relocated. The approach of -makefile variable overrides for each directory variable is required by -the GNU Coding Standards, and ideally causes no recompilation. -However, some platforms have known limitations with the semantics of -shared libraries that end up requiring recompilation when using this -method, particularly noticeable in packages that use GNU Libtool. - - The second method involves providing the `DESTDIR' variable. For -example, `make install DESTDIR=/alternate/directory' will prepend -`/alternate/directory' before all installation names. The approach of -`DESTDIR' overrides is not required by the GNU Coding Standards, and -does not work on platforms that have drive letters. On the other hand, -it does better at avoiding recompilation issues, and works well even -when some directory options were not specified in terms of `${prefix}' -at `configure' time. - -Optional Features -================= - - If the package supports it, you can cause programs to be installed -with an extra prefix or suffix on their names by giving `configure' the -option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. - - Some packages pay attention to `--enable-FEATURE' options to -`configure', where FEATURE indicates an optional part of the package. -They may also pay attention to `--with-PACKAGE' options, where PACKAGE -is something like `gnu-as' or `x' (for the X Window System). The -`README' should mention any `--enable-' and `--with-' options that the -package recognizes. - - For packages that use the X Window System, `configure' can usually -find the X include and library files automatically, but if it doesn't, -you can use the `configure' options `--x-includes=DIR' and -`--x-libraries=DIR' to specify their locations. - - Some packages offer the ability to configure how verbose the -execution of `make' will be. For these packages, running `./configure ---enable-silent-rules' sets the default to minimal output, which can be -overridden with `make V=1'; while running `./configure ---disable-silent-rules' sets the default to verbose, which can be -overridden with `make V=0'. - -Particular systems -================== - - On HP-UX, the default C compiler is not ANSI C compatible. If GNU -CC is not installed, it is recommended to use the following options in -order to use an ANSI C compiler: - - ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" - -and if that doesn't work, install pre-built binaries of GCC for HP-UX. - - On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot -parse its `' header file. The option `-nodtk' can be used as -a workaround. If GNU CC is not installed, it is therefore recommended -to try - - ./configure CC="cc" - -and if that doesn't work, try - - ./configure CC="cc -nodtk" - - On Solaris, don't put `/usr/ucb' early in your `PATH'. This -directory contains several dysfunctional programs; working variants of -these programs are available in `/usr/bin'. So, if you need `/usr/ucb' -in your `PATH', put it _after_ `/usr/bin'. - - On Haiku, software installed for all users goes in `/boot/common', -not `/usr/local'. It is recommended to use the following options: - - ./configure --prefix=/boot/common - -Specifying the System Type -========================== - - There may be some features `configure' cannot figure out -automatically, but needs to determine by the type of machine the package -will run on. Usually, assuming the package is built to be run on the -_same_ architectures, `configure' can figure that out, but if it prints -a message saying it cannot guess the machine type, give it the -`--build=TYPE' option. TYPE can either be a short name for the system -type, such as `sun4', or a canonical name which has the form: - - CPU-COMPANY-SYSTEM - -where SYSTEM can have one of these forms: - - OS - KERNEL-OS - - See the file `config.sub' for the possible values of each field. If -`config.sub' isn't included in this package, then this package doesn't -need to know the machine type. - - If you are _building_ compiler tools for cross-compiling, you should -use the option `--target=TYPE' to select the type of system they will -produce code for. - - If you want to _use_ a cross compiler, that generates code for a -platform different from the build platform, you should specify the -"host" platform (i.e., that on which the generated programs will -eventually be run) with `--host=TYPE'. - -Sharing Defaults -================ - - If you want to set default values for `configure' scripts to share, -you can create a site shell script called `config.site' that gives -default values for variables like `CC', `cache_file', and `prefix'. -`configure' looks for `PREFIX/share/config.site' if it exists, then -`PREFIX/etc/config.site' if it exists. Or, you can set the -`CONFIG_SITE' environment variable to the location of the site script. -A warning: not all `configure' scripts look for a site script. - -Defining Variables -================== - - Variables not defined in a site shell script can be set in the -environment passed to `configure'. However, some packages may run -configure again during the build, and the customized values of these -variables may be lost. In order to avoid this problem, you should set -them in the `configure' command line, using `VAR=value'. For example: - - ./configure CC=/usr/local2/bin/gcc - -causes the specified `gcc' to be used as the C compiler (unless it is -overridden in the site shell script). - -Unfortunately, this technique does not work for `CONFIG_SHELL' due to -an Autoconf bug. Until the bug is fixed you can use this workaround: - - CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash - -`configure' Invocation -====================== - - `configure' recognizes the following options to control how it -operates. - -`--help' -`-h' - Print a summary of all of the options to `configure', and exit. - -`--help=short' -`--help=recursive' - Print a summary of the options unique to this package's - `configure', and exit. The `short' variant lists options used - only in the top level, while the `recursive' variant lists options - also present in any nested packages. - -`--version' -`-V' - Print the version of Autoconf used to generate the `configure' - script, and exit. - -`--cache-file=FILE' - Enable the cache: use and save the results of the tests in FILE, - traditionally `config.cache'. FILE defaults to `/dev/null' to - disable caching. - -`--config-cache' -`-C' - Alias for `--cache-file=config.cache'. - -`--quiet' -`--silent' -`-q' - Do not print messages saying which checks are being made. To - suppress all normal output, redirect it to `/dev/null' (any error - messages will still be shown). - -`--srcdir=DIR' - Look for the package's source code in directory DIR. Usually - `configure' can determine that directory automatically. - -`--prefix=DIR' - Use DIR as the installation prefix. *note Installation Names:: - for more details, including other options available for fine-tuning - the installation locations. - -`--no-create' -`-n' - Run the configure checks, but stop before creating any output - files. - -`configure' also accepts some other, not widely useful, options. Run -`configure --help' for more details. - diff --git a/app/src/main/jni/simple-obfs/LICENSE b/app/src/main/jni/simple-obfs/LICENSE deleted file mode 100644 index e963df8..0000000 --- a/app/src/main/jni/simple-obfs/LICENSE +++ /dev/null @@ -1,622 +0,0 @@ - GNU GENERAL PUBLIC LICENSE - Version 3, 29 June 2007 - - Copyright (C) 2007 Free Software Foundation, Inc. - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - - Preamble - - The GNU General Public License is a free, copyleft license for -software and other kinds of works. - - The licenses for most software and other practical works are designed -to take away your freedom to share and change the works. By contrast, -the GNU General Public License is intended to guarantee your freedom to -share and change all versions of a program--to make sure it remains free -software for all its users. We, the Free Software Foundation, use the -GNU General Public License for most of our software; it applies also to -any other work released this way by its authors. You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -them if you wish), that you receive source code or can get it if you -want it, that you can change the software or use pieces of it in new -free programs, and that you know you can do these things. - - To protect your rights, we need to prevent others from denying you -these rights or asking you to surrender the rights. Therefore, you have -certain responsibilities if you distribute copies of the software, or if -you modify it: responsibilities to respect the freedom of others. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must pass on to the recipients the same -freedoms that you received. You must make sure that they, too, receive -or can get the source code. And you must show them these terms so they -know their rights. - - Developers that use the GNU GPL protect your rights with two steps: -(1) assert copyright on the software, and (2) offer you this License -giving you legal permission to copy, distribute and/or modify it. - - For the developers' and authors' protection, the GPL clearly explains -that there is no warranty for this free software. For both users' and -authors' sake, the GPL requires that modified versions be marked as -changed, so that their problems will not be attributed erroneously to -authors of previous versions. - - Some devices are designed to deny users access to install or run -modified versions of the software inside them, although the manufacturer -can do so. This is fundamentally incompatible with the aim of -protecting users' freedom to change the software. The systematic -pattern of such abuse occurs in the area of products for individuals to -use, which is precisely where it is most unacceptable. Therefore, we -have designed this version of the GPL to prohibit the practice for those -products. If such problems arise substantially in other domains, we -stand ready to extend this provision to those domains in future versions -of the GPL, as needed to protect the freedom of users. - - Finally, every program is threatened constantly by software patents. -States should not allow patents to restrict development and use of -software on general-purpose computers, but in those that do, we wish to -avoid the special danger that patents applied to a free program could -make it effectively proprietary. To prevent this, the GPL assures that -patents cannot be used to render the program non-free. - - The precise terms and conditions for copying, distribution and -modification follow. - - TERMS AND CONDITIONS - - 0. Definitions. - - "This License" refers to version 3 of the GNU General Public License. - - "Copyright" also means copyright-like laws that apply to other kinds of -works, such as semiconductor masks. - - "The Program" refers to any copyrightable work licensed under this -License. Each licensee is addressed as "you". "Licensees" and -"recipients" may be individuals or organizations. - - To "modify" a work means to copy from or adapt all or part of the work -in a fashion requiring copyright permission, other than the making of an -exact copy. The resulting work is called a "modified version" of the -earlier work or a work "based on" the earlier work. - - A "covered work" means either the unmodified Program or a work based -on the Program. - - To "propagate" a work means to do anything with it that, without -permission, would make you directly or secondarily liable for -infringement under applicable copyright law, except executing it on a -computer or modifying a private copy. Propagation includes copying, -distribution (with or without modification), making available to the -public, and in some countries other activities as well. - - To "convey" a work means any kind of propagation that enables other -parties to make or receive copies. Mere interaction with a user through -a computer network, with no transfer of a copy, is not conveying. - - An interactive user interface displays "Appropriate Legal Notices" -to the extent that it includes a convenient and prominently visible -feature that (1) displays an appropriate copyright notice, and (2) -tells the user that there is no warranty for the work (except to the -extent that warranties are provided), that licensees may convey the -work under this License, and how to view a copy of this License. If -the interface presents a list of user commands or options, such as a -menu, a prominent item in the list meets this criterion. - - 1. Source Code. - - The "source code" for a work means the preferred form of the work -for making modifications to it. "Object code" means any non-source -form of a work. - - A "Standard Interface" means an interface that either is an official -standard defined by a recognized standards body, or, in the case of -interfaces specified for a particular programming language, one that -is widely used among developers working in that language. - - The "System Libraries" of an executable work include anything, other -than the work as a whole, that (a) is included in the normal form of -packaging a Major Component, but which is not part of that Major -Component, and (b) serves only to enable use of the work with that -Major Component, or to implement a Standard Interface for which an -implementation is available to the public in source code form. A -"Major Component", in this context, means a major essential component -(kernel, window system, and so on) of the specific operating system -(if any) on which the executable work runs, or a compiler used to -produce the work, or an object code interpreter used to run it. - - The "Corresponding Source" for a work in object code form means all -the source code needed to generate, install, and (for an executable -work) run the object code and to modify the work, including scripts to -control those activities. However, it does not include the work's -System Libraries, or general-purpose tools or generally available free -programs which are used unmodified in performing those activities but -which are not part of the work. For example, Corresponding Source -includes interface definition files associated with source files for -the work, and the source code for shared libraries and dynamically -linked subprograms that the work is specifically designed to require, -such as by intimate data communication or control flow between those -subprograms and other parts of the work. - - The Corresponding Source need not include anything that users -can regenerate automatically from other parts of the Corresponding -Source. - - The Corresponding Source for a work in source code form is that -same work. - - 2. Basic Permissions. - - All rights granted under this License are granted for the term of -copyright on the Program, and are irrevocable provided the stated -conditions are met. This License explicitly affirms your unlimited -permission to run the unmodified Program. The output from running a -covered work is covered by this License only if the output, given its -content, constitutes a covered work. This License acknowledges your -rights of fair use or other equivalent, as provided by copyright law. - - You may make, run and propagate covered works that you do not -convey, without conditions so long as your license otherwise remains -in force. You may convey covered works to others for the sole purpose -of having them make modifications exclusively for you, or provide you -with facilities for running those works, provided that you comply with -the terms of this License in conveying all material for which you do -not control copyright. Those thus making or running the covered works -for you must do so exclusively on your behalf, under your direction -and control, on terms that prohibit them from making any copies of -your copyrighted material outside their relationship with you. - - Conveying under any other circumstances is permitted solely under -the conditions stated below. Sublicensing is not allowed; section 10 -makes it unnecessary. - - 3. Protecting Users' Legal Rights From Anti-Circumvention Law. - - No covered work shall be deemed part of an effective technological -measure under any applicable law fulfilling obligations under article -11 of the WIPO copyright treaty adopted on 20 December 1996, or -similar laws prohibiting or restricting circumvention of such -measures. - - When you convey a covered work, you waive any legal power to forbid -circumvention of technological measures to the extent such circumvention -is effected by exercising rights under this License with respect to -the covered work, and you disclaim any intention to limit operation or -modification of the work as a means of enforcing, against the work's -users, your or third parties' legal rights to forbid circumvention of -technological measures. - - 4. Conveying Verbatim Copies. - - You may convey verbatim copies of the Program's source code as you -receive it, in any medium, provided that you conspicuously and -appropriately publish on each copy an appropriate copyright notice; -keep intact all notices stating that this License and any -non-permissive terms added in accord with section 7 apply to the code; -keep intact all notices of the absence of any warranty; and give all -recipients a copy of this License along with the Program. - - You may charge any price or no price for each copy that you convey, -and you may offer support or warranty protection for a fee. - - 5. Conveying Modified Source Versions. - - You may convey a work based on the Program, or the modifications to -produce it from the Program, in the form of source code under the -terms of section 4, provided that you also meet all of these conditions: - - a) The work must carry prominent notices stating that you modified - it, and giving a relevant date. - - b) The work must carry prominent notices stating that it is - released under this License and any conditions added under section - 7. This requirement modifies the requirement in section 4 to - "keep intact all notices". - - c) You must license the entire work, as a whole, under this - License to anyone who comes into possession of a copy. This - License will therefore apply, along with any applicable section 7 - additional terms, to the whole of the work, and all its parts, - regardless of how they are packaged. This License gives no - permission to license the work in any other way, but it does not - invalidate such permission if you have separately received it. - - d) If the work has interactive user interfaces, each must display - Appropriate Legal Notices; however, if the Program has interactive - interfaces that do not display Appropriate Legal Notices, your - work need not make them do so. - - A compilation of a covered work with other separate and independent -works, which are not by their nature extensions of the covered work, -and which are not combined with it such as to form a larger program, -in or on a volume of a storage or distribution medium, is called an -"aggregate" if the compilation and its resulting copyright are not -used to limit the access or legal rights of the compilation's users -beyond what the individual works permit. Inclusion of a covered work -in an aggregate does not cause this License to apply to the other -parts of the aggregate. - - 6. Conveying Non-Source Forms. - - You may convey a covered work in object code form under the terms -of sections 4 and 5, provided that you also convey the -machine-readable Corresponding Source under the terms of this License, -in one of these ways: - - a) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by the - Corresponding Source fixed on a durable physical medium - customarily used for software interchange. - - b) Convey the object code in, or embodied in, a physical product - (including a physical distribution medium), accompanied by a - written offer, valid for at least three years and valid for as - long as you offer spare parts or customer support for that product - model, to give anyone who possesses the object code either (1) a - copy of the Corresponding Source for all the software in the - product that is covered by this License, on a durable physical - medium customarily used for software interchange, for a price no - more than your reasonable cost of physically performing this - conveying of source, or (2) access to copy the - Corresponding Source from a network server at no charge. - - c) Convey individual copies of the object code with a copy of the - written offer to provide the Corresponding Source. This - alternative is allowed only occasionally and noncommercially, and - only if you received the object code with such an offer, in accord - with subsection 6b. - - d) Convey the object code by offering access from a designated - place (gratis or for a charge), and offer equivalent access to the - Corresponding Source in the same way through the same place at no - further charge. You need not require recipients to copy the - Corresponding Source along with the object code. If the place to - copy the object code is a network server, the Corresponding Source - may be on a different server (operated by you or a third party) - that supports equivalent copying facilities, provided you maintain - clear directions next to the object code saying where to find the - Corresponding Source. Regardless of what server hosts the - Corresponding Source, you remain obligated to ensure that it is - available for as long as needed to satisfy these requirements. - - e) Convey the object code using peer-to-peer transmission, provided - you inform other peers where the object code and Corresponding - Source of the work are being offered to the general public at no - charge under subsection 6d. - - A separable portion of the object code, whose source code is excluded -from the Corresponding Source as a System Library, need not be -included in conveying the object code work. - - A "User Product" is either (1) a "consumer product", which means any -tangible personal property which is normally used for personal, family, -or household purposes, or (2) anything designed or sold for incorporation -into a dwelling. In determining whether a product is a consumer product, -doubtful cases shall be resolved in favor of coverage. For a particular -product received by a particular user, "normally used" refers to a -typical or common use of that class of product, regardless of the status -of the particular user or of the way in which the particular user -actually uses, or expects or is expected to use, the product. A product -is a consumer product regardless of whether the product has substantial -commercial, industrial or non-consumer uses, unless such uses represent -the only significant mode of use of the product. - - "Installation Information" for a User Product means any methods, -procedures, authorization keys, or other information required to install -and execute modified versions of a covered work in that User Product from -a modified version of its Corresponding Source. The information must -suffice to ensure that the continued functioning of the modified object -code is in no case prevented or interfered with solely because -modification has been made. - - If you convey an object code work under this section in, or with, or -specifically for use in, a User Product, and the conveying occurs as -part of a transaction in which the right of possession and use of the -User Product is transferred to the recipient in perpetuity or for a -fixed term (regardless of how the transaction is characterized), the -Corresponding Source conveyed under this section must be accompanied -by the Installation Information. But this requirement does not apply -if neither you nor any third party retains the ability to install -modified object code on the User Product (for example, the work has -been installed in ROM). - - The requirement to provide Installation Information does not include a -requirement to continue to provide support service, warranty, or updates -for a work that has been modified or installed by the recipient, or for -the User Product in which it has been modified or installed. Access to a -network may be denied when the modification itself materially and -adversely affects the operation of the network or violates the rules and -protocols for communication across the network. - - Corresponding Source conveyed, and Installation Information provided, -in accord with this section must be in a format that is publicly -documented (and with an implementation available to the public in -source code form), and must require no special password or key for -unpacking, reading or copying. - - 7. Additional Terms. - - "Additional permissions" are terms that supplement the terms of this -License by making exceptions from one or more of its conditions. -Additional permissions that are applicable to the entire Program shall -be treated as though they were included in this License, to the extent -that they are valid under applicable law. If additional permissions -apply only to part of the Program, that part may be used separately -under those permissions, but the entire Program remains governed by -this License without regard to the additional permissions. - - When you convey a copy of a covered work, you may at your option -remove any additional permissions from that copy, or from any part of -it. (Additional permissions may be written to require their own -removal in certain cases when you modify the work.) You may place -additional permissions on material, added by you to a covered work, -for which you have or can give appropriate copyright permission. - - Notwithstanding any other provision of this License, for material you -add to a covered work, you may (if authorized by the copyright holders of -that material) supplement the terms of this License with terms: - - a) Disclaiming warranty or limiting liability differently from the - terms of sections 15 and 16 of this License; or - - b) Requiring preservation of specified reasonable legal notices or - author attributions in that material or in the Appropriate Legal - Notices displayed by works containing it; or - - c) Prohibiting misrepresentation of the origin of that material, or - requiring that modified versions of such material be marked in - reasonable ways as different from the original version; or - - d) Limiting the use for publicity purposes of names of licensors or - authors of the material; or - - e) Declining to grant rights under trademark law for use of some - trade names, trademarks, or service marks; or - - f) Requiring indemnification of licensors and authors of that - material by anyone who conveys the material (or modified versions of - it) with contractual assumptions of liability to the recipient, for - any liability that these contractual assumptions directly impose on - those licensors and authors. - - All other non-permissive additional terms are considered "further -restrictions" within the meaning of section 10. If the Program as you -received it, or any part of it, contains a notice stating that it is -governed by this License along with a term that is a further -restriction, you may remove that term. If a license document contains -a further restriction but permits relicensing or conveying under this -License, you may add to a covered work material governed by the terms -of that license document, provided that the further restriction does -not survive such relicensing or conveying. - - If you add terms to a covered work in accord with this section, you -must place, in the relevant source files, a statement of the -additional terms that apply to those files, or a notice indicating -where to find the applicable terms. - - Additional terms, permissive or non-permissive, may be stated in the -form of a separately written license, or stated as exceptions; -the above requirements apply either way. - - 8. Termination. - - You may not propagate or modify a covered work except as expressly -provided under this License. Any attempt otherwise to propagate or -modify it is void, and will automatically terminate your rights under -this License (including any patent licenses granted under the third -paragraph of section 11). - - However, if you cease all violation of this License, then your -license from a particular copyright holder is reinstated (a) -provisionally, unless and until the copyright holder explicitly and -finally terminates your license, and (b) permanently, if the copyright -holder fails to notify you of the violation by some reasonable means -prior to 60 days after the cessation. - - Moreover, your license from a particular copyright holder is -reinstated permanently if the copyright holder notifies you of the -violation by some reasonable means, this is the first time you have -received notice of violation of this License (for any work) from that -copyright holder, and you cure the violation prior to 30 days after -your receipt of the notice. - - Termination of your rights under this section does not terminate the -licenses of parties who have received copies or rights from you under -this License. If your rights have been terminated and not permanently -reinstated, you do not qualify to receive new licenses for the same -material under section 10. - - 9. Acceptance Not Required for Having Copies. - - You are not required to accept this License in order to receive or -run a copy of the Program. Ancillary propagation of a covered work -occurring solely as a consequence of using peer-to-peer transmission -to receive a copy likewise does not require acceptance. However, -nothing other than this License grants you permission to propagate or -modify any covered work. These actions infringe copyright if you do -not accept this License. Therefore, by modifying or propagating a -covered work, you indicate your acceptance of this License to do so. - - 10. Automatic Licensing of Downstream Recipients. - - Each time you convey a covered work, the recipient automatically -receives a license from the original licensors, to run, modify and -propagate that work, subject to this License. You are not responsible -for enforcing compliance by third parties with this License. - - An "entity transaction" is a transaction transferring control of an -organization, or substantially all assets of one, or subdividing an -organization, or merging organizations. If propagation of a covered -work results from an entity transaction, each party to that -transaction who receives a copy of the work also receives whatever -licenses to the work the party's predecessor in interest had or could -give under the previous paragraph, plus a right to possession of the -Corresponding Source of the work from the predecessor in interest, if -the predecessor has it or can get it with reasonable efforts. - - You may not impose any further restrictions on the exercise of the -rights granted or affirmed under this License. For example, you may -not impose a license fee, royalty, or other charge for exercise of -rights granted under this License, and you may not initiate litigation -(including a cross-claim or counterclaim in a lawsuit) alleging that -any patent claim is infringed by making, using, selling, offering for -sale, or importing the Program or any portion of it. - - 11. Patents. - - A "contributor" is a copyright holder who authorizes use under this -License of the Program or a work on which the Program is based. The -work thus licensed is called the contributor's "contributor version". - - A contributor's "essential patent claims" are all patent claims -owned or controlled by the contributor, whether already acquired or -hereafter acquired, that would be infringed by some manner, permitted -by this License, of making, using, or selling its contributor version, -but do not include claims that would be infringed only as a -consequence of further modification of the contributor version. For -purposes of this definition, "control" includes the right to grant -patent sublicenses in a manner consistent with the requirements of -this License. - - Each contributor grants you a non-exclusive, worldwide, royalty-free -patent license under the contributor's essential patent claims, to -make, use, sell, offer for sale, import and otherwise run, modify and -propagate the contents of its contributor version. - - In the following three paragraphs, a "patent license" is any express -agreement or commitment, however denominated, not to enforce a patent -(such as an express permission to practice a patent or covenant not to -sue for patent infringement). To "grant" such a patent license to a -party means to make such an agreement or commitment not to enforce a -patent against the party. - - If you convey a covered work, knowingly relying on a patent license, -and the Corresponding Source of the work is not available for anyone -to copy, free of charge and under the terms of this License, through a -publicly available network server or other readily accessible means, -then you must either (1) cause the Corresponding Source to be so -available, or (2) arrange to deprive yourself of the benefit of the -patent license for this particular work, or (3) arrange, in a manner -consistent with the requirements of this License, to extend the patent -license to downstream recipients. "Knowingly relying" means you have -actual knowledge that, but for the patent license, your conveying the -covered work in a country, or your recipient's use of the covered work -in a country, would infringe one or more identifiable patents in that -country that you have reason to believe are valid. - - If, pursuant to or in connection with a single transaction or -arrangement, you convey, or propagate by procuring conveyance of, a -covered work, and grant a patent license to some of the parties -receiving the covered work authorizing them to use, propagate, modify -or convey a specific copy of the covered work, then the patent license -you grant is automatically extended to all recipients of the covered -work and works based on it. - - A patent license is "discriminatory" if it does not include within -the scope of its coverage, prohibits the exercise of, or is -conditioned on the non-exercise of one or more of the rights that are -specifically granted under this License. You may not convey a covered -work if you are a party to an arrangement with a third party that is -in the business of distributing software, under which you make payment -to the third party based on the extent of your activity of conveying -the work, and under which the third party grants, to any of the -parties who would receive the covered work from you, a discriminatory -patent license (a) in connection with copies of the covered work -conveyed by you (or copies made from those copies), or (b) primarily -for and in connection with specific products or compilations that -contain the covered work, unless you entered into that arrangement, -or that patent license was granted, prior to 28 March 2007. - - Nothing in this License shall be construed as excluding or limiting -any implied license or other defenses to infringement that may -otherwise be available to you under applicable patent law. - - 12. No Surrender of Others' Freedom. - - If conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot convey a -covered work so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you may -not convey it at all. For example, if you agree to terms that obligate you -to collect a royalty for further conveying from those to whom you convey -the Program, the only way you could satisfy both those terms and this -License would be to refrain entirely from conveying the Program. - - 13. Use with the GNU Affero General Public License. - - Notwithstanding any other provision of this License, you have -permission to link or combine any covered work with a work licensed -under version 3 of the GNU Affero General Public License into a single -combined work, and to convey the resulting work. The terms of this -License will continue to apply to the part which is the covered work, -but the special requirements of the GNU Affero General Public License, -section 13, concerning interaction through a network will apply to the -combination as such. - - 14. Revised Versions of this License. - - The Free Software Foundation may publish revised and/or new versions of -the GNU General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - - Each version is given a distinguishing version number. If the -Program specifies that a certain numbered version of the GNU General -Public License "or any later version" applies to it, you have the -option of following the terms and conditions either of that numbered -version or of any later version published by the Free Software -Foundation. If the Program does not specify a version number of the -GNU General Public License, you may choose any version ever published -by the Free Software Foundation. - - If the Program specifies that a proxy can decide which future -versions of the GNU General Public License can be used, that proxy's -public statement of acceptance of a version permanently authorizes you -to choose that version for the Program. - - Later license versions may give you additional or different -permissions. However, no additional obligations are imposed on any -author or copyright holder as a result of your choosing to follow a -later version. - - 15. Disclaimer of Warranty. - - THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY -APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT -HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY -OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, -THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM -IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF -ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. Limitation of Liability. - - IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS -THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY -GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE -USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF -DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD -PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), -EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF -SUCH DAMAGES. - - 17. Interpretation of Sections 15 and 16. - - If the disclaimer of warranty and limitation of liability provided -above cannot be given local legal effect according to their terms, -reviewing courts shall apply local law that most closely approximates -an absolute waiver of all civil liability in connection with the -Program, unless a warranty or assumption of liability accompanies a -copy of the Program in return for a fee. - - END OF TERMS AND CONDITIONS - diff --git a/app/src/main/jni/simple-obfs/Makefile.am b/app/src/main/jni/simple-obfs/Makefile.am deleted file mode 100644 index d5da3ab..0000000 --- a/app/src/main/jni/simple-obfs/Makefile.am +++ /dev/null @@ -1,7 +0,0 @@ -SUBDIRS = libcork src - -if ENABLE_DOCUMENTATION -SUBDIRS += doc -endif - -ACLOCAL_AMFLAGS = -I m4 diff --git a/app/src/main/jni/simple-obfs/README.md b/app/src/main/jni/simple-obfs/README.md deleted file mode 100644 index e8bb724..0000000 --- a/app/src/main/jni/simple-obfs/README.md +++ /dev/null @@ -1,102 +0,0 @@ -# simple-obfs - -## Intro - -Simple-obfs is a simple obfusacting tool, designed as plugin server of shadowsocks. - -Current version: 0.0.5 | [Changelog](Changes) - -## Build -For Unix-like systems, especially Debian-based systems, -e.g. Ubuntu, Debian or Linux Mint, you can build the binary like this: - -```bash -# Debian / Ubuntu -sudo apt-get install --no-install-recommends build-essential autoconf libtool libssl-dev libpcre3-dev libev-dev asciidoc xmlto automake -# CentOS / Fedora / RHEL -sudo yum install gcc autoconf libtool automake make zlib-devel openssl-devel asciidoc xmlto -# Arch -sudo pacman -Syu gcc autoconf libtool automake make zlib openssl asciidoc xmlto -# Alpine -apk add gcc autoconf make libtool automake zlib-devel openssl asciidoc xmlto libpcre32 libev-dev g++ linux-headers - -git clone https://github.com/shadowsocks/simple-obfs.git -cd simple-obfs -git submodule update --init --recursive -./autogen.sh -./configure && make -sudo make install -``` -## Usage - -For a detailed and complete list of all supported arguments, you may refer to the -man pages of the applications, respectively. - -### Plugin mode with shadowsocks - -Add respective item to `--plugin` and `--plugin-opts` arg or as value of `plugin` and `plugin_opts` in JSON. - -On the client: - -```bash -ss-local -c config.json --plugin obfs-local --plugin-opts "obfs=http;obfs-host=www.bing.com" -``` - -On the server: - -```bash -ss-server -c config.json --plugin obfs-server --plugin-opts "obfs=http" -``` - -### Standalone mode - -On the client: - -```bash -obfs-local -s server_ip -p 8139 -l 1984 --obfs http --obfs-host www.bing.com -ss-local -c config.json -s 127.0.0.1 -p 1984 -l 1080 -``` - -On the server: - -```bash -obfs-server -s server_ip -p 8139 --obfs http -r 127.0.0.1:8388 -ss-server -c config.json -s 127.0.0.1 -p 8388 -``` - -### Coexist with an actual Web server - -Only applicable on the server: - -```bash -# HTTP only with plugin mode -ss-server -c config.json --plugin obfs-server --plugin-opts "obfs=http;failover=example.com" - -# Both HTTP and HTTPS with standalone mode -obfs-server -s server_ip -p 80 --obfs http -r 127.0.0.1:8388 --failover example.com -obfs-server -s server_ip -p 443 --obfs tls -r 127.0.0.1:8388 --failover example.com - -# suppose you have an HTTP webserver (apache/nginx/whatever) listening on localhost:8080 and HTTPS on 8443 -# (you probably shouldn't expose these ports) -obfs-server -s server_ip -p 80 --obfs http -r 127.0.0.1:8388 --failover 127.0.0.1:8080 -obfs-server -s server_ip -p 443 --obfs tls -r 127.0.0.1:8388 --failover 127.0.0.1:8443 -``` - -## License - -``` -Copyright (C) 2016 Max Lv - -This program is free software: you can redistribute it and/or modify -it under the terms of the GNU General Public License as published by -the Free Software Foundation, either version 3 of the License, or -(at your option) any later version. - -This program is distributed in the hope that it will be useful, -but WITHOUT ANY WARRANTY; without even the implied warranty of -MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

It's a “simple, easily embeddable, -cross-platform C library”. It falls roughly into the same category as -[glib](http://library.gnome.org/devel/glib/) or -[APR](http://apr.apache.org/) in the C world; the STL, -[POCO](http://pocoproject.org/), or [QtCore](http://qt.nokia.com/) -in the C++ world; or the standard libraries of any decent dynamic -language. - -So if libcork has all of these comparables, why a new library? Well, -none of the C++ options are really applicable here. And none of the C -options work, because one of the main goals is to have the library be -highly modular, and useful in resource-constrained systems. Once we -describe some of the design decisions that we've made in libcork, you'll -hopefully see how this fits into an interesting niche of its own. - -## Using libcork - -There are two primary ways to use libcork in your own software project: -as a _shared library_, or _embedded_. - -When you use libcork as a shared library, you install it just like you -would any other C library. We happen to use CMake as our build system, -so you follow the usual CMake recipe to install the library. (See the -[INSTALL](INSTALL) file for details.) All of the libcork code is -contained within a single shared library (called libcork.so, -libcork.dylib, or cork.dll, depending on the system). We also install a -pkg-config file that makes it easy to add the appropriate compiler flags -in your own build scripts. So, you use pkg-config to find libcork's -include and library files, link with libcork, and you're good to go. - -The alternative is to embed libcork into your own software project's -directory structure. In this case, your build scripts compile the -libcork source along with the rest of your code. This has some -advantages for resource-constrained systems, since (assuming your -compiler and linker are any good), you only include the libcork routines -that you actually use. And if your toolchain supports link-time -optimization, the libcork routines can be optimized into the rest of -your code. - -Which should you use? That's really up to you. Linking against the -shared library adds a runtime dependency, but gives you the usual -benefits of shared libraries: the library in memory is shared across -each program that uses it; you can install a single bug-fix update and -all libcork programs automatically take advantage of the new release; -etc. The embedding option is great if you really need to make your -library as small as possible, or if you don't want to add that runtime -dependency. - -## Design decisions - -Note that having libcork be **easily** embeddable has some ramifications -on the library's design. In particular, we don't want to make any -assumptions about which build system you're embedding libcork into. We -happen to use CMake, but you might be using autotools, waf, scons, or -any number of others. Most cross-platform libraries follow the -autotools model of performing some checks at compile time (maybe during -a separate “configure” phase, maybe not) to choose the right API -implementation for the current platform. Since we can't assume a build -system, we have to take a different approach, and do as many checks as -we can using the C preprocessor. Any check that we can't make in the -preprocessor has to be driven by a C preprocessor macro definition, -which you (the libcork user) are responsible for checking for and -defining. So we need to have as few of those as possible. diff --git a/app/src/main/jni/simple-obfs/libcork/cmake/FindCTargets.cmake b/app/src/main/jni/simple-obfs/libcork/cmake/FindCTargets.cmake deleted file mode 100644 index 455d428..0000000 --- a/app/src/main/jni/simple-obfs/libcork/cmake/FindCTargets.cmake +++ /dev/null @@ -1,215 +0,0 @@ -# -*- coding: utf-8 -*- -# ---------------------------------------------------------------------- -# Copyright © 2015, RedJack, LLC. -# All rights reserved. -# -# Please see the COPYING file in this distribution for license details. -# ---------------------------------------------------------------------- -

If the user only specifies - the name of the command set, then we'll print out a list of this set's - subcommands, along with their short descriptions. (For instance, running - ``set`` on its own would describe the ``set add``, ``set query``, ``set - remove``, ``set union``, and ``set print`` subcommands.

You don't need to -do anything special, except for ensuring that the actual help text that you -provide to the :c:macro:`cork_leaf_command` and :c:macro:`cork_command_set` -macros defined is intelligble and useful. - -Your executable will automatically include a ``help`` command in every command -set, as well as ``--help`` and ``-h`` options in every command set and leaf -command. So all of the following would print out the help text for the ``set -add`` command: - -.. code-block:: none - - $ set help add - $ set add --help - $ set add -h - -And all of the following would print out the list of ``set print`` subcommands: - -.. code-block:: none - - $ set help print - $ set print --help - $ set print -h - -You can also print out the help text for a command explicitly by calling the -following function: - -.. function:: void cork_command_show_help(struct cork_command \*command, const char \*message) - - Prints out help text for *command*. (If it's a leaf command, this is the - full help text. If it's a command set, it's a list of the set's - subcommands.) We will preface the help text with *message* if it's - non-``NULL``. (The message should not include a trailing newline.) - - -.. _cli-options: - -Option parsing -============== - -Leaf commands and command sets both let you provide a function that parse -command-line options for the given command. We don't prescribe any particular -option parsing library, you just need to conform to the interface described in -this section. (Note that the standard ``getopt`` and ``getopt_long`` functions -can easily be used in an option parsing function.) - -.. type:: int (\*cork_option_parser)(int argc, char \*\*argv) - - Should parse any command-line options that can appear at this point in the - executable's command line. (The options must appear immediately after the - name of the command that this function belongs to. See below for several - examples.) - - Your function must look for and process any options that appear at the - beginning of *argv*. If there are any errors processing the options, you - should print out an error message (most likely via - :c:func:`cork_command_show_help`) and exit the program, using the standard - ``exit`` function, with an exit code of ``EXIT_FAILURE``. - - If there aren't any errors processing the options, you should return the - number of *argv* elements that were consumed while processing the options. - We will use this return value to update *argc* and *argv* beforing continuing - with subcommand selection and argument processing. (Note that ``getopt``'s - ``optind`` variable is exactly what you need for the return value.) - -As mentioned above, different option parsing functions are used to parse options -from a particular point in the command line. Given the following command: - -.. code-block:: none - - $ set --opt1 print --opt2 avro --opt3 --opt4=foo - -The ``--opt1`` option would be parsed by the ``set`` command's parser. The -``--opt2`` option would be parsed by the ``set print`` command's parser. The -``--opt3`` and ``-opt4=foo`` options would be parsed by the ``set print avro`` -command's parser. And the ```` argument would be parsed by the ``set -print avro`` command's *run* function. diff --git a/app/src/main/jni/simple-obfs/libcork/docs/old/conf.py b/app/src/main/jni/simple-obfs/libcork/docs/old/conf.py deleted file mode 100644 index 6484a5e..0000000 --- a/app/src/main/jni/simple-obfs/libcork/docs/old/conf.py +++ /dev/null @@ -1,80 +0,0 @@ -# -*- coding: utf-8 -*- - -import sys, os - -extensions = ['sphinx.ext.mathjax'] -source_suffix = '.rst' -master_doc = 'index' -project_name = u'libcork' -project_slug = u'libcork' -company = u'RedJack, LLC' -copyright_years = u'2011-2012' - -default_role = 'c:func' -primary_domain = 'c' - -rst_epilog = """ -.. |project_name| replace:: """ + project_name + """ -""" - -# Intersphinx stuff - -# If your documentation uses intersphinx to link to other Sphinx -# documentation sets, uncomment and fill in the following. -# -#intersphinx_mapping = { -# 'libcork': ('http://libcork.readthedocs.org/en/latest/', None), -#} - -# Our CMake build scripts will insert overrides below if the prereq -# libraries have installed their Sphinx documentation locally.

The list will initially be empty. - - The second variant is a static initializer, that lets you initialize a list - at compile time, rather than runtime. You must pass in the name of the list - for this to work, since we need to be able to extract pointers into the list - object. - - -Querying a list ---------------- - -.. function:: size_t cork_dllist_size(const struct cork_dllist \*list) - - Returns the number of elements in *list*. - - This operation runs in :math:`O(n)` time. - - -.. function:: bool cork_dllist_is_empty(struct cork_dllist \*list) - - Returns whether *list* is empty. - - This operation runs in :math:`O(1)` time. - - -Editing a list --------------- - -.. function:: void cork_dllist_add_to_head(struct cork_dllist \*list, struct cork_dllist_item \*element) - void cork_dllist_add_to_tail(struct cork_dllist \*list, struct cork_dllist_item \*element) - - Adds *element* to *list*. The ``_head`` variant adds the new element to the - beginning of the list; the ``_tail`` variant adds it to the end. - - You are responsible for allocating the list element yourself, most likely by - allocating the ``struct`` that you've embedded :c:type:`cork_dllist_item` - into. - - .. note:: - - This function assumes that *element* isn't already a member of a different - list.

The first is that you --- or really, your C -library --- has to ensure that ``errno`` is placed in thread-local storage, so -that separate threads have their own error condition variables.

Like standard POSIX-conforming -functions, you return an integer status code from any function that might need -to report an error to its caller.

If it's relative, it will be interpreted relative to the - current directory. If *path* doesn't exist, or there are any problems - reading the contents of the directory, we'll set an error condition and - return ``-1``. - - To process the contents of the directory, you must provide a *walker* object, - which contains several callback methods that we will call when files and - subdirectories of *path* are encountered.

LNCS 2072. - - -Creating a garbage collector -============================ - -.. function:: void cork_gc_init(void) - - Initalizes a garbage collection context for the current thread. - Usually, you can allocate this on the stack of your ``main`` - function:: - - int - main(int argc, char ** argv) - { - cork_gc_init(); - - // use the GC context - - // and free it when you're done - cork_gc_done(); - } - - It's not required that you call this function at all; if you don't, - we'll automatically initialize a garbage collection context for the - current thread the first time you try to allocate a garbage-collected - object. You can call this function, though, if you want to have more - control over when the initialization occurs. - -.. function:: void cork_gc_done(void) - - Finalize the garbage collection context for the current thread. All - objects created in this thread will be freed when this function - returns. - - You must call this function in each thread that allocates - garbage-collected objects, just before that thread finishes. (If - your application is single-threaded, then you must call this function - before the ``main`` function finishes.) If you don't, you'll almost - certainly get memory leaks. - - -Managing garbage-collected objects -================================== - -A garbage collection context can't be used to manage arbitrary objects, -since each garbage-collected class must define some callback functions -for interacting with the garbage collector. (The :ref:`next section -` contains more details.) - -Each garbage-collected class will provide its own constructor function -for instantiating a new instance of that class. There aren't any -explicit destructors for garbage-collected objects; instead you manage -“references” to the objects. Each pointer to a garbage-collected object -is a reference, and each object maintains a count of the references to -itself. A newly constructed object starts with a reference count of -``1``. Whenever you save a pointer to a garbage-collected object, you -should increase the object's reference count. When you're done with the -pointer, you decrease its reference count. When the reference count -drops to ``0``, the garbage collector frees the object. - -.. function:: void \*cork_gc_incref(void \*obj) - - Increments the reference count of an object *obj* that is managed by - the current thread's garbage collector. We always return *obj* as a - result, which allows you to use the following idiom:: - - struct my_obj * my_copy_of_obj = cork_gc_incref(obj); - -.. function:: void cork_gc_decref(void \*obj) - - Decrements the reference count of an object *obj* that is managed by - the current thread's garbage collector If the reference count drops - to ``0``, then the garbage collector will free the object. - - .. note:: - - It's safe to call this function with a ``NULL`` *obj* pointer; in - this case, the function acts as a no-op. - -.. _borrow-ref: - -Borrowing a reference ---------------------- - -While the strategy mentioned above implies that you should call -:c:func:`cork_gc_incref()` and :c:func:`cork_gc_decref()` for *every* -pointer to a garbage-collected object, you can sometimes get away -without bumping the reference count. In particular, you can often -*borrow* an existing reference to an object, if you can guarantee that -the borrowed reference will exist for as long as you need access to the -object. The most common example of this when you pass in a -garbage-collected object as the parameter to a function:: - - int - use_new_reference(struct my_obj *obj) - { - /* Here we're being pedantically correct, and incrementing obj's - * reference count since we've got our own pointer to the object. */ - cork_gc_incref(obj); - - /* Do something useful with obj */ - - /* And now that we're done with it, decrement the reference count. */ - cork_gc_decref(obj); - } - - int - borrowed_reference(struct my_obj *obj) - { - /* We can assume that the caller has a valid reference to obj, so - * we're just going to borrow that reference. */ - - /* Do something useful with obj */ - } - -In this example, ``borrowed_reference`` doesn't need to update *obj*\ 's -reference count. We assume that the caller has a valid reference to -*obj* when it makes the call to ``borrowed_reference``. Moreover, we -know that the caller can't possibly release this reference (via -:c:func:`cork_gc_decref()`) until ``borrowed_reference`` returns. Since -we can guarantee that the caller's reference to *obj* will exist for the -entire duration of ``borrowed_reference``, we don't need to protect it -with an ``incref``/``decref`` pair. - -.. _steal-ref: - -Stealing a reference --------------------- - -Another common pattern is for a “parent” object to maintain a reference -to a “child” object. (For example, a container class might maintain -references to all of the elements in the container, assuming that the -container and elements are all garbage-collected objects.) When you -have a network of objects like this, the parent object's constructor -will usually take in a pointer to the child object as a parameter. If -we strictly follow the basic referencing counting rules described above, -you'll end up with something like:: - - struct child *child = child_new(); - struct parent *parent = parent_new(child); - cork_gc_decref(child); - -The ``child_new`` constructor gives us a reference to *child*. The -``parent_new`` constructor then creates a new reference to *child*, -which will be stored somewhere in *parent*. We no longer need our own -reference to *child*, so we immediately decrement its reference count. - -This is a common enough occurrence that many constructor functions will -instead *steal* the reference passed in as a parameter. This means that -the constructor takes control of the caller's reference. This allows us -to rewrite the example as:: - - struct parent *parent = parent_new_stealing(child_new()); - -For functions that steal a reference, the caller **cannot** assume that -the object pointed to by the stolen reference exists when the function -returns. (If there's an error in ``parent_new_stealing``, for instance, -it must release the stolen reference to *child* to prevent a memory -leak.) If a function is going to steal a reference, but you also need -to use the object after the function call returns, then you need to -explicitly increment the reference count *before* calling the function:: - - struct child *child = child_new(); - struct parent *parent = parent_new_stealing(cork_gc_incref(child)); - /* Do something with child. */ - /* And then release our reference when we're done. */ - cork_gc_decref(child); - -.. note:: - - It's important to point out that not every constructor will steal the - references passed in as parameters. Moreover, there are some - constructors that steal references for some parameters but not for - others. It entirely depends on what the “normal” use case is for the - constructor. If you're almost always going to pass in a child object - that was just created, and that will always be accessed via the - parent, then the constructor will usually steal the reference. If - the child can be referenced by many parents, then the constructor - will usually *not* steal the reference. The documentation for each - constructor function will explicitly state which references are - stolen and which objects it creates new references for. - - -.. _new-gc-class: - -Writing a new garbage-collected class -===================================== - -When you are creating a new class that you want to be managed by a -garbage collector, there are two basic steps you need to follow: - -* Implement a set of callback functions that allow the garbage collector - to interact with objects of the new class. - -* Use the garbage collector's allocation functions to allocate storage - for instance of your class. - -You won't need to write a public destructor function, since objects of -the new class will be destroyed automatically when the garbage collector -determines that they're no longer needed. - -Garbage collector callback interface ------------------------------------- - -Each garbage-collected class must provide an implementation of the -“callback interface”: - -.. type:: struct cork_gc_obj_iface - - .. member:: void (\*free)(void \*obj) - - This callback is called when a garbage-collected object is about - to be freed. You can perform any special cleanup steps in this - callback. You do **not** need to deallocate the object's storage, - and you do **not** need to release any references that you old to - other objects. Both of these steps will be taken care of for you - by the garbage collector. - - If your class doesn't need any additional finalization steps, this - entry in the callback interface can be ``NULL``. - - .. member:: void (\*recurse)(struct cork_gc \*gc, void \*obj, cork_gc_recurser recurse, void \*ud) - - This callback is how you inform the garbage collector of your - references to other garbage-collected objects. - - The garbage collector will call this function whenever it needs to - traverse through a graph of object references. Your - implementation of this callback should just call *recurse* with - each garbage-collected object that you hold a reference to. You - must pass in *gc* as the first parameter to each call to - *recurse*, and *ud* as the third parameter. - - Note that it's fine to call *recurse* with a ``NULL`` object - pointer, which makes it slightly easier to write implementations - of this callback. - - If instances of your class can never contain references to other - garbage-collected objects, this entry in the callback interface - can be ``NULL``. - -.. type:: void (\*cork_gc_recurser)(struct cork_gc \*gc, void \*obj, void \*ud) - - An opaque callback provided by the garbage collector when it calls an - object's :c:member:`~cork_gc_obj_iface.recurse` method. - -.. type:: struct cork_gc - - An opaque type representing the current thread's garbage-collection - context. You'll only need to use this type when implementing a - :c:member:`~cork_gc_obj_iface.recurse` function. - - -.. _gc-macros: - -Helper macros -~~~~~~~~~~~~~ - -There are several macros declared in :file:`libcork/helpers/gc.h` that -make it easier to define the garbage-collection interface for a new -class. - -.. note:: - - Unlike most libcork modules, these macros are **not** automatically - defined when you include the ``libcork/core.h`` header file, since - they don't include a ``cork_`` prefix. Because of this, we don't - want to pollute your namespace unless you ask for the macros. To do - so, you must explicitly include their header file:: - - #include - -.. macro:: _free_(SYMBOL name) - _recurse_(SYMBOL name) - - These macros declare the *free* and *recurse* methods for a new - class. The functions will be declared with exactly the signatures - and parameter names shown in the entries for the - :c:member:`~cork_gc_obj_iface.free` and - :c:member:`~cork_gc_obj_iface.recurse` methods. - - You will almost certainly not need to refer to the method - implementations directly, since you can use the :c:macro:`_gc_*_ - <_gc_>` macros below to declare the interface struct. But if you do, - they'll be called :samp:`{[name]}__free` and - :samp:`{[name]}__recurse`. (Note the double underscore.) - -.. macro:: _gc_(SYMBOL name) - _gc_no_free_(SYMBOL name) - _gc_no_recurse_(SYMBOL name) - _gc_leaf_(SYMBOL name) - - Define the garbage-collection interface struct for a new class. If - you defined both ``free`` and ``recurse`` methods, you should use the - ``_gc_`` variant. If you only defined one of the methods, you should - use ``_gc_no_free_`` or ``_gc_no_recurse_``. If you didn't define - either method, you should use ``_gc_free_``. - - Like the method definitions, you probably won't need to refer to the - interface struct directly, since you can use the - :c:func:`cork_gc_new` macro to allocate new instances of the new - class. But if you do, it will be called :samp:`{[name]}__gc`. (Note - the double underscore.) - - -As an example, we can use these macros to define a new tree class:: - - #include - - struct tree { - const char *name; - struct tree *left; - struct tree *right; - }; - - _free_(tree) { - struct tree *self = obj; - cork_strfree(self->name); - } - - _recurse_(tree) { - struct tree *self = obj; - recurse(self->left, ud); - recurse(self->right, ud); - } - - _gc_(tree); - - -Allocating new garbage-collected objects ----------------------------------------- - -In your garbage-collected class's constructor, you must use one of the -following functions to allocate the object's storage. (The garbage -collector hides some additional state in the object's memory region, so -you can't allocate the storage using ``malloc`` or :c:func:`cork_new()` -directly.) - -.. function:: void \*cork_gc_alloc(size_t instance_size, struct cork_gc_obj_iface \*iface) - - Allocates a new garbage-collected object that is *instance_size* - bytes large. *iface* should be a pointer to a callback interface for - the object. If there are any problems allocating the new instance, - the program will abort. - -.. function:: type \*cork_gc_new_iface(TYPE type, struct cork_gc_obj_iface \*iface) - - Allocates a new garbage-collected instance of *type*.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary.
