Announcing Release 22 of the PostgreSQL Buildfarm client

New features

* PGXSExtension module — a single config-driven module for testing
out-of-tree PGXS extensions, keyed by a |pgxs_extensions| hash in the
config (one entry per extension). New test extensions no longer need
their own bespoke |.pm| file. The existing BlackholeFDW,
FileTextArrayFDW
and RedisFDW modules remain for now so existing configs keep working.
* New branches-to-build tags |UNRELEASED| and |HEAD_PLUS_UNRELEASED|,
covering branches between the time the tree is forked and a release is
tagged.
* CheckIndent can now run on any branch that loads it, not just HEAD.
* |locales| entries can now be a hashref naming both the locale and the
encoding, e.g. |{ locale => 'C', encoding => 'UTF8' }|. Encodings are
compared canonically.
* Build result submission is retried (up to 5 times, 60 seconds apart)
when
the server answers with HTTP 503 "Backend Fetch Failed".
* The client version number is now included in the user agent string.

PatchStack improvements

* Apply the patch series with the patches repository's own
|import-series.pl| driver when present, so the farm tests exactly what a
release wrap produces. Otherwise apply with |git apply| rather than
|git quiltimport|, at full context.
* Decide whether a rebuild is needed from the net result of applying the
series, so a branch is rebuilt when a patch it shares from another
branch's directory (e.g. |../master/foo.patch|) changes.
* Resolve symlinked and shared patches via git plumbing.
* New |PGBuild::PatchSeries| module for shared series reading, and a new
|check_patch_stack.pl| script to check a patch stack.
* Write a |patch_stack.log| for distinct display on the server.
* Optional diagnostic snapshot of repository git state (|diagnose => 1|).
* Clear stale |git am| state left behind by a failed or killed run, which
previously caused every later run to fail on the first patch.
* Don't send the previous run's stage logs when reporting a checkout
failure.
* Handle a series file with no entries.
* Automatic git maintenance is forced off under |git_use_workdirs|,
and the
sample config now recommends turning |git_use_workdirs| off for
PatchStack animals.

Log collection

* Don't attach server and node logs to passing make/MSVC stages (only TAP
|regress_log_*| files), matching the meson behaviour. On valgrind
animals, logs reporting valgrind errors are still kept, and installcheck
server logs are now checked for valgrind errors.
* Don't resend the failure log when it is already in a stage log. (This
needs a server that understands |failed_stage_log|.)

Cross-version upgrade

* Pin the dump session time zone to UTC, so comparisons don't fail
spuriously when saved data directories come from a machine in a
different time zone.
* Stop the server before bailing out on error.

Bug fixes

* Fix |use_vpath|/|using_meson| handling for MSVC animals that prefer
meson
but fall back to the legacy MSVC build on branches without
|meson.build|.
* In PGXS TAP test directories, run only the TAP tests (from release 12,
|make check| also ran the REGRESS and ISOLATION suites, which are run
elsewhere).
* Fixes for Windows with TAP and Unix sockets, and a backslash issue.
* Remove a robocopy flag (|/sec|) that upset Windows 11.
* Remove an unwanted system call in |Dist.pm|.

Housekeeping

* Make LF the canonical line ending for text files.
* perlcritic and perltidy cleanups.
