A collection of scripts for Gentoo development.

Miscellaneous

QA

• find-new-pkg-by: list new packages by a maintainer (useful for finding e.g. proxied maintainers who add more packages than they maintain, and possibly directing them to GURU for such bits)

• find-unmaintained: find packages nominally maintained but with no commits from their maintainer recently

• report-bugs-pkgcheck: report bugs on Bugzilla en-masse for packages triggering a given pkgcheck check/warning

Keywords

• at-find-unkeyworded-for-arch: find packages unkeyworded for ${TARGET_ARCH} relative to ${BASE_ARCH} (e.g. suppose trying to get riscv parity with arm64)

• find-unkeyworded: find packages which have an unkeyworded version in ::gentoo for all arches. This sometimes happens and is forgotten about after committing something "unkeyworded for testing".

Maintenance

• gbump: bump group of packages (and commits if desired). Calls bump-generic under the hood.

• bump-generic: bumps package to new version, copying from last visible version in the repository. Used as a basis for other scripts too.

• bump-go: bumps Go package to a new version (generates dependency tarball for you).

• bump-rust: bumps Rust package to a new version (generates CRATES variable contents for you) (NOTE: deprecated in favour of app-portage/pycargoebuild).

• git-revbump-all: revbump all changed packages (NOTE: this needs some fixes first, see comment at top of script)

Niche

• generate-cmake-docs: generate man page tarball for dev-util/cmake

• generate-libunwind-docs: generate man page tarball for sys-libs/libunwind

• generate-sshuttle-docs: generate man page tarball for net-proxy/sshuttle

• generate-qemu-docs: generate man page tarball for app-emulation/qemu

• generate-pkgdev-docs: generate man page tarball for dev-util/pkgdev

• generate-libabigail-docs: generate man page tarball for dev-util/libabigail

• generate-iputils-docs: generate man page tarball for net-misc/iputils

• generate-ccache-docs: generate man page tarball for dev-util/ccache

• generate-libnet-docs: generate man page tarball for net-libs/libnet

• generate-pipewire-docs: generate man page tarball for media-video/pipewire

• gather-keys: generate a clean keyring containing keys for a list of given fingerprints after scraping keyservers for them.

git

Assorted scripts

• check-all-changed-pkgs: run ebuild .. clean prepare (or up to some other phase) on all packages with local pending changes. Useful for ensuring e.g. mass revbumps or other QA fixes haven't broken e.g. applying patches (think of e.g. ${PF} being used in PATCHES)

• commit-changed-pkgs: commits each of the local changes per-package with a given commit message

• sort-branch origin/master my-changes: sorts commits by commit summary - does all work in a temporary branch and leaves my-changes alone. Can choose to throw away the sorted branch if merge conflicts occur

rebase-filter-maint

Takes a branch and creates a filtered version based on included/excluded maintainers. Optionally can create the inverse too.

Suppose you have a branch with changes across the Gentoo tree affecting a range of maintainers.

Usage

$ cd ~/git/gentoo
$ git checkout my-large-change-set
# Make your changes!
# Configure the script as appropriate
$ bash ~/scripts/rebase-filter-maint --maintainer «maintainer regex»
$ git checkout my-large-change-set-identifier-blacklist

The maintainer regex may also be provided by providing the maintainers envvar before the script is called.

By default the script will operate on your working branch. This may be changed by passing --minefield «branch name»

The default configuration is to blacklist commits (i.e. cherry pick everything that doesn't match your regex). The inverse can be achieved by providing the --whitelist flag.

Note:

• The script does not currently handle passing both --whitelist and --blacklist; results may be unpredictable.
• When run this script will perform a git reset on origin/master.

Example (whitelist)

Our branch is controversial with a load of changes some people might want to discuss, but others you know are okay with.

You might set the list to be maintainers with whom you have a good rapport and choose the whitelist mode.

rebase-filter-maint will then create a branch called controversial-${identifier}-whitelist containing all commits affecting those maintainers, so you can push it straight away.

If you choose, rebase-filter-maint will create an inverse branch called controversial-${identifier}-blacklist containing all commits affecting non-listed maintainers. This is a branch you might have to submit for review or similar.

Example (blacklist)

Our branch is straightforward and we think the changes are non-controversial, but we want to leave certain packages maintained by e.g. base-system@ or toolchain@ because those deserve extra care due to their importance.

In this case, you might want to choose the blacklist mode.

rebase-filter-maint will then create a branch called straightforward-${identifier}-blacklist which contains all commits that need more care. This is a branch you might have to submit for review or similar.

If you choose, rebase-filter-maint will create an inverse branch called straightforward-${identifier}-whitelist containing all commits affecting maintainers whose packages we can touch. This is a branch you might be able to just push.

gcc

• generate_snapshot_index.py: Generates a text file known_snapshots.txt which indexes snapshots and the commit they were based on.

• bisect-gcc: Unpolished script used for git bisect run when bisecting GCC.

• bisect-binutils: Ditto.

• bisect-gdb: Ditto.

• miscompile-reduce.sh: Script for reducing miscompilations w/ cvise.

llvm

• build-llvm: Sets args I usually want for CMake, bit like bisect-gcc.
