From fe84b9869424785d174cfc6750ec03f414e06794 Mon Sep 17 00:00:00 2001 From: Ryan Breen Date: Tue, 13 Jan 2026 07:17:24 -0500 Subject: [PATCH] feat(net): add HTTP/1.1 client library with comprehensive test suite Implements HTTP client for Breenix networking stack: - URL parsing with scheme validation (HTTP only, HTTPS rejected) - DNS hostname resolution integration - TCP socket connection management - HTTP/1.1 GET request building with proper headers - Response parsing (status codes, headers, body extraction) Test coverage includes: - URL validation (port ranges, format, length limits) - HTTPS rejection error handling - Invalid domain DNS error handling - Network connectivity (with SKIP markers when unavailable) Also fixes build warnings: - Added #[allow(dead_code)] for legitimate HAL API elements - Fixed unused variable warnings in tcp_socket_test.rs - Cleaned up unused assignments throughout test files Co-Authored-By: Claude Opus 4.5 --- kernel/build.rs | 1 + kernel/src/arch_impl/traits.rs | 5 + kernel/src/arch_impl/x86_64/constants.rs | 6 + kernel/src/arch_impl/x86_64/cpu.rs | 5 + .../src/arch_impl/x86_64/interrupt_frame.rs | 7 + kernel/src/arch_impl/x86_64/mod.rs | 15 + kernel/src/arch_impl/x86_64/paging.rs | 5 + kernel/src/arch_impl/x86_64/percpu.rs | 5 + kernel/src/arch_impl/x86_64/pic.rs | 7 + kernel/src/arch_impl/x86_64/privilege.rs | 7 + kernel/src/arch_impl/x86_64/timer.rs | 5 + kernel/src/main.rs | 14 + kernel/src/net/mod.rs | 3 +- kernel/src/net/tcp.rs | 30 +- kernel/src/syscall/handler.rs | 5 - kernel/src/time/tsc.rs | 2 + libs/libbreenix/src/http.rs | 391 ++++++++++++++++++ libs/libbreenix/src/lib.rs | 1 + userspace/tests/Cargo.toml | 4 + userspace/tests/build.sh | 1 + userspace/tests/cow_cleanup_test.rs | 3 +- userspace/tests/http_test.rs | 332 +++++++++++++++ userspace/tests/tcp_socket_test.rs | 72 ++-- xtask/src/main.rs | 53 +++ 24 files changed, 925 insertions(+), 54 deletions(-) create mode 100644 libs/libbreenix/src/http.rs create mode 100644 userspace/tests/http_test.rs diff --git a/kernel/build.rs b/kernel/build.rs index fc101ac..7e88bf2 100644 --- a/kernel/build.rs +++ b/kernel/build.rs @@ -107,6 +107,7 @@ fn main() { println!("cargo:rerun-if-changed={}/job_control_test.rs", userspace_tests); println!("cargo:rerun-if-changed={}/session_test.rs", userspace_tests); println!("cargo:rerun-if-changed={}/job_table_test.rs", userspace_tests); + println!("cargo:rerun-if-changed={}/http_test.rs", userspace_tests); println!("cargo:rerun-if-changed={}/pipeline_test.rs", userspace_tests); println!("cargo:rerun-if-changed={}/sigchld_job_test.rs", userspace_tests); println!("cargo:rerun-if-changed={}/lib.rs", libbreenix_dir.to_str().unwrap()); diff --git a/kernel/src/arch_impl/traits.rs b/kernel/src/arch_impl/traits.rs index 284a847..1cdb525 100644 --- a/kernel/src/arch_impl/traits.rs +++ b/kernel/src/arch_impl/traits.rs @@ -2,6 +2,11 @@ //! //!
