Some of you may already know about it but, now that it has been tested a bit more, felt should advertise here.
It's small'ish scripts available from "app-portage/iwdevtools"
See github[1]'s README.rst for a lowdown (and --help or man pages for
options), but for a quick overview:
qa-vdb:
Looks at VDB's (/var/db/pkg) information and suggest changes if
something is unexpected, such as a used shared library that isn't
in RDEPEND.
Can be optionally integrated with portage to display post-emerge:
* QA: detected possibly incorrect RDEPEND
* dev-db/sqlite <
* dev-libs/glib | dev-libs/glib:2
* > media-libs/libogg
* > sys-libs/readline:=
(Says to remove sqlite, add :2, add missing libogg / readline.
Will be optionally colored, like :2 in a different color.)
It's only suggestions and still needs someone to verify (e.g.
dlopen() is unknown to the tool, or if a package uses bin/openssl
executable and not its libraries), exclusion rules or disabling
some checks entirely (like explicit :SLOT) can be done as needed
if don't want to be nagged for your packages when you know it's
right.
qa-sed:
Attempts to detect when a sed(1) command in an ebuild did nothing,
indicating that it (probably) needs updating or cleanup.
qa-cmp:
Compares portage install images (tmp/<cat>/<pkg>/image) either with
each others or with system's copy to give an overview of changes.
Can also be optionally integrated to display post-emerge:
* QA: comparing =media-libs/libid3tag-0.15.1b-r4 with <snip>
* FILES:+usr/lib64/cmake/id3tag/id3tagConfig.cmake
* FILES:+usr/lib64/cmake/id3tag/id3tagConfigVersion.cmake
* FILES:+usr/lib64/cmake/id3tag/id3tagTargets-gentoo.cmake
* FILES:+usr/lib64/cmake/id3tag/id3tagTargets.cmake
* FILES:-usr/lib64/libid3tag.so.0
* FILES:-usr/lib64/libid3tag.so.0.3.0
* FILES:+usr/lib64/libid3tag.so.${PV}
* SONAME:-libid3tag.so.0(64)
* SONAME:+libid3tag.so.0.16.1(64)
* ------> FILES(+5,-2) SONAME(+1,-1)
(In this example it's showing us the SONAME change needs some
looking into. Can display/hide other information like simple
size and ABI changes with abidiff(1), or simple full lists.)
eoldnew:
Minor helper to emerge previous version then latest, can be useful
with qa-cmp when old wasn't already installed.
scrub-patch:
This takes the devmanual's "clean patches" sed[2] and additionally
performs basic checks on making patches a bit better and to spot a
handful of possible oversights.
These are still experimental but should usually work fine.
More small tools may be added in the future.
If any issues / questions / suggestions, feel welcome to mention them
to me on Libera IRC (nick: ionen), github[1], or b.g.o as preferred.
