Default package analysis should show "what provides" info

[efahl]

As of 0c7b579 the default package analysis changed from:

Default package analysis:
  Default              Provided-by
  dnsmasq              default package replaced/provided by dnsmasq-full
  kmod-dwmac-intel     Warning: default package is not present
  libustream-mbedtls   Warning: default package is not present
  nftables             default package replaced/provided by nftables-json

to showing

Default package analysis:
  Default              Provided-by
  dnsmasq              not installed, possibly replaced by another package
  kmod-dwmac-intel     not installed, possibly replaced by another package
  libustream-mbedtls   not installed, possibly replaced by another package
  nftables             not installed, possibly replaced by another package

In the previous version, the package database was consulted to see if the default package is being provided by another installed package, allowing for a much better understanding of the installation.

The plan is to investigate adding a parameter to ubus rpc-sys packagelist call, such that a "provider" option would produce the installed package or packages providing the capability.

$ ubus call rpc-sys packagelist '{"provider": "dnsmasq"}'
{ [ "dnsmasq-full" ] }

https://github.com/openwrt/rpcd/blob/master/sys.c
https://wiki.alpinelinux.org/wiki/Apk_spec#APKINDEX_Format - see the p: entry for 'provides'

CLI analogs:

$ opkg whatprovides dnsmasq
What provides dnsmasq
    dnsmasq-full

$ apk list --installed --providers dnsmasq
<dnsmasq> dnsmasq-2.90-r3 x86_64 {dnsmasq} (GPL-2.0-or-later)

[efahl]

Functionality restored in 1ed0c8d by running opkg and apk commands.

Still needs a proper solution as proposed above.

Is this a bug in the current solution?

WARNING: There are 1 missing default packages, confirm this is expected before proceeding

And:

# owut list | xargs -n 1 echo | sort | grep -E 'nftables|wpad'
-nftables
-wpad-basic-mbedtls
wpad-mesh-mbedtls
# opkg whatprovides wpa-supplicant
What provides wpa-supplicant
    wpad-mesh-mbedtls
# opkg whatprovides hostapd
What provides hostapd
    wpad-mesh-mbedtls
# opkg whatprovides nftables
What provides nftables
    nftables-json
# 

Note that nftables-json is NOT listed in owut list

[efahl]

Note that nftables-json is NOT listed in owut list

nftables-json is the default package that supplies the nftables virtual package, so it doesn't appear as one of the top-level packages that owut list shows.

$ opkg list 'nftable*'
nftables-json - 1.1.1-r1 - nftables userspace utility with JSON support
nftables-nojson - 1.1.1-r1 - nftables userspace utility no JSON support

It's all a confusing idiosyncrasy of the current packaging and defaults, maybe we'll fix it up with the new packaging we're working on with apk...
