Portage

--------------

Breaking changes:
* eend: Missing argument is now an error (bug 703520).

* ebuild.sh: A colon in sandbox function args is now an error (bug 920654).

Security:
* make.globals: disable FEATURES="sfperms" by default (bug 938164).

* emerge-webrsync: Create /var/db/repos/gentoo with correct permissions to
facilitate FEATURES="usersync" (bug 707980).

Features:
* New 'home-dir-template-copy' FEATURE (bug 947822).

If enabled, as part of the ebuild environment setup, copies the PORTAGE_USERNAME
home directory into the build environment HOME directory. Useful predominantly
for ebuilds that use the git-r3 eclass, to give a place to put SSH keys and user-
specific git configuration files used during the build.

* Flush the merge-wait queue on SIGUSR2.

Bug fixes:
* depgraph: Ignore blockers when computing virtual deps visibility (PR 1387).

* binarytree: Fix _inject_repo_revisions to ignore remote packages for which
source repostories are missing, triggering KeyError (PR 1391).

* gpkg: do not consider symlinks targets for size estimation (bug 942512).

* install_qa_check: Fix noclean interaction with merge-wait (bug 942760).

* save-ebuild-env.sh: Add functions from newer EAPIs to filter list

* Support cross-root package moves (bug 946326).

* Process elog messages for emerge --config (bug 904702).

* Scheduler: Handle SIGWINCH for JobStatusDisplay (bug 945382).

* Pass through MAKEFLAGS and exclude from environment.bz2 (bug 692576).

* binarytree.move_ent: Allocate path with binpkg_format (bug 923530).

* ebuild.sh: Allow CC and CXX to be changed in profile.bashrc.

* Preserve PORTAGE_BZIP2_COMMAND in environment.bz2 (bug 948067).

* config: Initialize default PORTAGE_USERNAME and PORTAGE_GRPNAME (bug 941977).

* rust-rebuild: Update for recent changes in ::gentoo (bug 906044).

* emerge-webrsync: Use variables PORTAGE_USERNAME and PORTAGE_GRPNAME (bug 707980).

Cleanups:
* eapi.sh: Remove support for unofficial 4-slot-abi EAPI.

* locks: Drop comment regarding sleep() call.

--------------

Bug fixes:
* JobStatusDisplay: Fix width of display. Notable with the new 'merge wait'
metric.

* install-qa-check.d: 90config-impl-decl: Skip various false positives.

--------------

Features:
* binrepos.conf: Support custom download location (bug 934784).

In binrepos.conf, 'location' can now be set to choose the location
for fetched binpkgs from a particular remote repository.

* emerge: Make bare --root-deps option install build-time dependencies to ROOT
as well as / for all EAPIs rather than instead of / for EAPI 6 and below
(bug 435066).

* Show length of merge-wait queue as part of the status display.

* src: Allow GIL to be disabled for Whirlpool C extension (bug 934220).

* ELF: Recognise BPF (bug 937485).

* portage.util.compression_probe: Handle lack of ctypes (libffi) for
bootstrapping purposes.

Bug fixes:
* ebuild: Handle Bash 5.2's change in behavior which enables the shopt
'globskipdots' by default. This is needed to avoid breaking existing
working ebuilds. Future EAPIs will need to adjust the logic
added by this change. See bug 907061.

* doebuild.spawn: Fix hang with FEATURES="network-sandbox-proxy" in consumers
like gentoolkit (bug 937384).

* make.globals: add bcachefs_effective.* and bcachefs.* to PORTAGE_XATTR_EXCLUDE

* vartree, movefile: Warn when rewriting a symlink (bug 934514).

* repository: config: Allow a repository to be configured using one of its
aliases rather than its primary name (bug 935830).

* emerge: Fix parallel-fetch to properly terminate FETCHCOMMAND processes when
needed, using a SIGTERM handler (bug 936273).

* unpack: Don't display "Unpacking ..." message for skipped files.
Match file extensions case-sensitively in old EAPIs, fixes PMS compliance.

* sync: zipfile: Fix installing module.

* ebuild: Improve 'maintainer mode' QA check.

* emerge-webrsync: Honour sync-webrsync-verify-signature attribute.

* dispatch-conf: Don't use SHELL (bug 910560).

* phase-functions: Fix QA_SONAME_NO_SYMLINK so it accepts regex (bug 924953).

* ebuild.5: Improve QA_PREBUILT docs.

* install-qa-check.d: 90gcc-warnings: Handle color in logs for build.log too.

Cleanups:
* tar_safe_extract: Port to Python 3.14 (bug 933433).

* Drop unnecessary f-string use.

* Improve detection of xtrace (debugging).

* eapi.py: Use attrs rather than hardcoding / repeating EAPI properties.

--------------

Features:
* binrepos.conf: Support "frozen" attribute (bug 932739).

This avoids mutating the local index cache by fetching changes from a
binpkg host when running emerge repeatedly. It's useful for consistency
between emerge runs while completing an update.

It should only be used temporarily, not set on a permanent basis.

* bintree: Add REPO_REVISIONS to Packages index header (bug 924772).

Portage will now store synced revisions at /var/lib/portage/repo_revisions.

This associates a binpkg being built with the repository state / revision
at a time, which will ultimately later allow pinning binhost clients
to <= the last commit the binhost was updated at.

It's also useful for pinning source builds from the same revision as
when binary builds were done for consistency and to minimize rebuilds and
maximize binpkg use.

* mtimedb: Record binpkg BUILD_ID and BUILD_TIME (bug 933442).

This fixes 'emerge --resume' to correctly pick up binpkgs and not
recalculate.

Bug fixes:
* unpack: Skip unrecognized file formats silently, fixing PMS compliance.

* estrip: Don't use splitdebug for .o files (bug 787623).

This fixes splitdebug mangling debug information with Clang.

* sync: git: Add safe.directory for getting HEAD commit (bug 930992).

* install-qa-checks.d: 90config-impl-decl: Suppress known false positives
for gnulib on glibc and musl.

* CONFIG_PROTECT: Don't use shlex.split (as it's a whitespace-separated list).

* depgraph: Fix crash with --useoldpkg with subslot bumps (bug 932804).

* depgraph: find_smallest_cycle: Revert optimization which caused
merge order regression (bug 922629).

A new testcase is also added.

* sync: Don't use IPv6 for rsync when disabled (bug 927241).

* atomic_ofstream: Use mkstemp instead of PID for PID namespace safety (bug 851015).

* MergeProcess: Pass bintree to subprocess (bug 933297).

This fixes FEATURES="downgrade-backup".

* tar_stream_writer: Improve error handling (bug 933385).

Cleanups:
* Scheduler: Improve legibility.

* portage.util.shlex_split: Drop legacy Python 2 wrapper.

* eapi.sh: Drop obsolete ___eapi_has_dohtml_deprecated().

--------------

Features:
* Scheduler: Support parallel-install with merge-wait (bug 256616, bug 925213).

This makes the (future) improvement mentioned in portage-3.0.62's NEWS.

* phase-functions: prematurely delete WORKDIR if FEATURES=merge-wait

The 'merge-wait' feature could lead to running out of disk space on
PORTAGE_TMPDIR's filesystem because many more workdirs were kept around
until merging was queued up. We now purge the workdirs but keep the image
around until merging.

* Start to record REPO_REVISIONS in build-info in VDB (bug 924772).

Ultimately the intention is to expose this information in binhost
metadata so that clients can select consistent revisions of source
repositories.

* util: file_copy: Support btrfs's FICLONE ioctl for fast file clones.

Added when implementing the below 'src: Drop linux_reflink C module.'
cleanup.

* sync: Add new 'zipfile' sync-type.

This allows fetching ebuild repositories via snapshots from e.g. GitHub,
gitweb, cgit.

Bug fixes:
* ctypes: Add workaround for loading libc on musl.

* util: set a timeout for urlopen calls (bug 926221).

* SpawnProcess: Fix noise / warnings caused by set_term_size (bug 923750, bug 925456).

* binpkg, gpkg: Add missing newlines to error messages.

* writable_check: Improve whitespace handling when parsing /proc/self/mountinfo (bug 925888).

* doebuild: Call _setup_locale (bug 925863).

This is needed to more robustly handle invalid or inappropriate locale settings.

* binarytree._populate_remote: Fix UnboundLocalError for binpkg-request-signature (bug 926048).

* elog/mod_custom: Spawn processes in background (bug 925907).

Fixes a noisy crash on exit.

* Fix REQUIRED_USE error with --fetchonly --pretend but not --fetchonly (bug 675748).

* socks5: Fix exit with FEATURES="network-sandbox-proxy" or FEATURES="distcc" (bug 925240).

* meson.build: Install dist-info METADATA (bug 920330).

This is needed for 'pip' to not be confused when Portage is installed system-wide.

* EbuildPhase/EbuildBinpkg: Ensure PKGDIR subdirectory permissions (bug 712222).

A warning (failure) was observed with FEATURES="installsources" otherwise.

* config: Sort FEATURES to avoid non-determinism (bug 914441).

* man: Document autoenabled options by --getbinpkgonly.

* BinpkgPrefetcher: Use eerror for binarytree inject failures (bug 927632).

This improves the readability of the error substantially.

* install-qa-check.d: Remove QA warning when no bash completions are found (bug 928599, bug 928869).

This check had too many false positives.

* lib: use more pure git-describe output for --version (bug 912209).

This makes 'emerge --version' info far nicer when using portage-9999.

* lib: adhere to python package version conventions (bug 926966).

(Note that this needed fixing even before the change for bug 912209).

Cleanups:
* cnf: sets: Migrate golang-rebuild to dev-lang/go (removed from Portage) (bug 919751).

* src: Drop libc C module.

This was only used for `find_library` on musl. We've now implemented
an alternative workaround for this.

* src: Drop linux_reflink C module.

This is now implemented in pure Python, which also means PyPy can
benefit.

Testsuite coverage was also improved for this area.

* Delete compat_coroutine module.

--------------

Bug fixes:
* emerge: Skip installed packages with emptytree in depgraph selection (bug 651018).

* bin/install-qa-check.d: 90gcc-warnings: drop warnings with too many FPs (bug 925460).

* AsyncioEventLoop: Call process.run_exitfuncs() before close (bug 925240).

Fixes hang with FEATURES="network-sandbox-proxy" or FEATURES="distcc".

* SchedulerInterface/PollScheduler: Add _loop property (bug 925333).

Fixes erroneous assert.

* _dynamic_deps_preload: Fix settings reference (bug 925350).

Fix KeyError with --dynamic-deps.

* process.spawn: Fix logic for missing libc.unshare on musl (bug 925311).

Fix handling when we can't unshare where we might e.g. modify the hostname
of the real system on musl.

* dbapi: Fix TypeError when passing Exception to warnings.warn (bug 922935).

Fix testUpdateDbentryDbapiTestCase.

* _start_proc: Prevent premature ForkProcess garbage collection (bug 925456).

Fix warnings/errors like "[ERROR] Task was destroyed but it is pending!".

Cleanups:
* More asyncio porting.
