Git 2.33 Release Notes
|
|
======================
|
|
|
|
Updates since Git 2.32
|
|
----------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* "git send-email" learned the "--sendmail-cmd" command line option
|
|
and the "sendemail.sendmailCmd" configuration variable, which is a
|
|
more sensible approach than the current way of repurposing the
|
|
"smtp-server" that is meant to name the server to instead name the
|
|
command to talk to the server.
|
|
|
|
* The userdiff pattern for C# learned the token "record".
|
|
|
|
* "git rev-list" learns to omit the "commit <object-name>" header
|
|
lines from the output with the `--no-commit-header` option.
|
|
|
|
* "git worktree add --lock" learned to record why the worktree is
|
|
locked with a custom message.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* The code to handle the "--format" option in "for-each-ref" and
|
|
friends made too many string comparisons on %(atom)s used in the
|
|
format string, which has been corrected by converting them into
|
|
enum when the format string is parsed.
|
|
|
|
* Use the hashfile API in the codepath that writes the index file to
|
|
reduce code duplication.
|
|
|
|
* Repeated rename detections in a sequence of mergy operations have
|
|
been optimized out for the 'ort' merge strategy.
|
|
|
|
* Preliminary clean-up of tests before the main reftable changes
|
|
hits the codebase.
|
|
|
|
* The backend for "diff -G/-S" has been updated to use pcre2 engine
|
|
when available.
|
|
|
|
* Use ".DELETE_ON_ERROR" pseudo target to simplify our Makefile.
|
|
|
|
* Code cleanup around struct_type_init() functions.
|
|
|
|
* "git send-email" optimization.
|
|
|
|
* GitHub Actions / CI update.
|
|
(merge 0dc787a9f2 js/ci-windows-update later to maint).
|
|
|
|
* Object accesses in repositories with many alternate object store
|
|
have been optimized.
|
|
|
|
* "git log" has been optimized not to waste cycles to load ref
|
|
decoration data that may not be needed.
|
|
|
|
* Many "printf"-like helper functions we have have been annotated
|
|
with __attribute__() to catch placeholder/parameter mismatches.
|
|
|
|
* Tests that cover protocol bits have been updated and helpers
|
|
used there have been consolidated.
|
|
|
|
* The CI gained a new job to run "make sparse" check.
|
|
|
|
* "git status" codepath learned to work with sparsely populated index
|
|
without hydrating it fully.
|
|
|
|
* A guideline for gender neutral documentation has been added.
|
|
|
|
* Documentation on "git diff -l<n>" and diff.renameLimit have been
|
|
updated, and the defaults for these limits have been raised.
|
|
|
|
* The completion support used to offer alternate spelling of options
|
|
that exist only for compatibility, which has been corrected.
|
|
|
|
* "TEST_OUTPUT_DIRECTORY=there make test" failed to work, which has
|
|
been corrected.
|
|
|
|
* "git bundle" gained more test coverage.
|
|
|
|
* "git read-tree" had a codepath where blobs are fetched one-by-one
|
|
from the promisor remote, which has been corrected to fetch in bulk.
|
|
|
|
* Rewrite of "git submodule" in C continues.
|
|
|
|
* "git checkout" and "git commit" learn to work without unnecessarily
|
|
expanding sparse indexes.
|
|
|
|
|
|
Fixes since v2.32
|
|
-----------------
|
|
|
|
* We historically rejected a very short string as an author name
|
|
while accepting a patch e-mail, which has been loosened.
|
|
(merge 72ee47ceeb ef/mailinfo-short-name later to maint).
|
|
|
|
* The parallel checkout codepath did not initialize object ID field
|
|
used to talk to the worker processes in a futureproof way.
|
|
|
|
* Rewrite code that triggers undefined behaviour warning.
|
|
(merge aafa5df0df jn/size-t-casted-to-off-t-fix later to maint).
|
|
|
|
* The description of "fast-forward" in the glossary has been updated.
|
|
(merge e22f2daed0 ry/clarify-fast-forward-in-glossary later to maint).
|
|
|
|
* Recent "git clone" left a temporary directory behind when the
|
|
transport layer returned an failure.
|
|
(merge 6aacb7d861 jk/clone-clean-upon-transport-error later to maint).
|
|
|
|
* "git fetch" over protocol v2 left its side of the socket open after
|
|
it finished speaking, which unnecessarily wasted the resource on
|
|
the other side.
|
|
(merge ae1a7eefff jk/fetch-pack-v2-half-close-early later to maint).
|
|
|
|
* The command line completion (in contrib/) learned that "git diff"
|
|
takes the "--anchored" option.
|
|
(merge d1e7c2cac9 tb/complete-diff-anchored later to maint).
|
|
|
|
* "git-svn" tests assumed that "locale -a", which is used to pick an
|
|
available UTF-8 locale, is available everywhere. A knob has been
|
|
introduced to allow testers to specify a suitable locale to use.
|
|
(merge 482c962de4 dd/svn-test-wo-locale-a later to maint).
|
|
|
|
* Update "git subtree" to work better on Windows.
|
|
(merge 77f37de39f js/subtree-on-windows-fix later to maint).
|
|
|
|
* Remove multimail from contrib/
|
|
(merge f74d11471f js/no-more-multimail later to maint).
|
|
|
|
* Make the codebase MSAN clean.
|
|
(merge 4dbc55e87d ah/uninitialized-reads-fix later to maint).
|
|
|
|
* Work around inefficient glob substitution in older versions of bash
|
|
by rewriting parts of a test.
|
|
(merge eb87c6f559 jx/t6020-with-older-bash later to maint).
|
|
|
|
* Avoid duplicated work while building reachability bitmaps.
|
|
(merge aa9ad6fee5 jk/bitmap-tree-optim later to maint).
|
|
|
|
* We broke "GIT_SKIP_TESTS=t?000" to skip certain tests in recent
|
|
update, which got fixed.
|
|
|
|
* The side-band demultiplexer that is used to display progress output
|
|
from the remote end did not clear the line properly when the end of
|
|
line hits at a packet boundary, which has been corrected.
|
|
|
|
* Some test scripts assumed that readlink(1) was universally
|
|
installed and available, which is not the case.
|
|
(merge 7c0afdf23c jk/test-without-readlink-1 later to maint).
|
|
|
|
* Recent update to completion script (in contrib/) broke those who
|
|
use the __git_complete helper to define completion to their custom
|
|
command.
|
|
(merge cea232194d fw/complete-cmd-idx-fix later to maint).
|
|
|
|
* Output from some of our tests were affected by the width of the
|
|
terminal that they were run in, which has been corrected by
|
|
exporting a fixed value in the COLUMNS environment.
|
|
(merge c49a177bec ab/fix-columns-to-80-during-tests later to maint).
|
|
|
|
* On Windows, mergetool has been taught to find kdiff3.exe just like
|
|
it finds winmerge.exe.
|
|
(merge 47eb4c6890 ms/mergetools-kdiff3-on-windows later to maint).
|
|
|
|
* When we cannot figure out how wide the terminal is, we use a
|
|
fallback value of 80 ourselves (which cannot be avoided), but when
|
|
we run the pager, we export it in COLUMNS, which forces the pager
|
|
to use the hardcoded value, even when the pager is perfectly
|
|
capable to figure it out itself. Stop exporting COLUMNS when we
|
|
fall back on the hardcoded default value for our own use.
|
|
(merge 9b6e2c8b98 js/stop-exporting-bogus-columns later to maint).
|
|
|
|
* "git cat-file --batch-all-objects"" misbehaved when "--batch" is in
|
|
use and did not ask for certain object traits.
|
|
(merge ee02ac6164 zh/cat-file-batch-fix later to maint).
|
|
|
|
* Some code and doc clarification around "git push".
|
|
|
|
* The "union" conflict resultion variant misbehaved when used with
|
|
binary merge driver.
|
|
(merge 382b601acd jk/union-merge-binary later to maint).
|
|
|
|
* Prevent "git p4" from failing to submit changes to binary file.
|
|
(merge 54662d5958 dc/p4-binary-submit-fix later to maint).
|
|
|
|
* "git grep --and -e foo" ought to have been diagnosed as an error
|
|
but instead segfaulted, which has been corrected.
|
|
(merge fe7fe62d8d rs/grep-parser-fix later to maint).
|
|
|
|
* The merge code had funny interactions between content based rename
|
|
detection and directory rename detection.
|
|
(merge 3585d0ea23 en/merge-dir-rename-corner-case-fix later to maint).
|
|
|
|
* When rebuilding the multi-pack index file reusing an existing one,
|
|
we used to blindly trust the existing file and ended up carrying
|
|
corrupted data into the updated file, which has been corrected.
|
|
(merge f89ecf7988 tb/midx-use-checksum later to maint).
|
|
|
|
* Update the location of system-side configuration file on Windows.
|
|
(merge e355307692 js/gfw-system-config-loc-fix later to maint).
|
|
|
|
* Code recently added to support common ancestry negotiation during
|
|
"git push" did not sanity check its arguments carefully enough.
|
|
(merge eff40457a4 ab/fetch-negotiate-segv-fix later to maint).
|
|
|
|
* Update the documentation not to assume users are of certain gender
|
|
and adds to guidelines to do so.
|
|
(merge 46a237f42f ds/gender-neutral-doc later to maint).
|
|
|
|
* "git commit --allow-empty-message" won't abort the operation upon
|
|
an empty message, but the hint shown in the editor said otherwise.
|
|
(merge 6f70f00b4f hj/commit-allow-empty-message later to maint).
|
|
|
|
* The code that gives an error message in "git multi-pack-index" when
|
|
no subcommand is given tried to print a NULL pointer as a strong,
|
|
which has been corrected.
|
|
(merge 88617d11f9 tb/reverse-midx later to maint).
|
|
|
|
* CI update.
|
|
(merge a066a90db6 js/ci-check-whitespace-updates later to maint).
|
|
|
|
* Documentation fix for "git pull --rebase=no".
|
|
(merge d3236becec fc/pull-no-rebase-merges-theirs-into-ours later to maint).
|
|
|
|
* A race between repacking and using pack bitmaps has been corrected.
|
|
(merge dc1daacdcc jk/check-pack-valid-before-opening-bitmap later to maint).
|
|
|
|
* The local changes stashed by "git merge --autostash" were lost when
|
|
the merge failed in certain ways, which has been corrected.
|
|
|
|
* Windows rmdir() equivalent behaves differently from POSIX ones in
|
|
that when used on a symbolic link that points at a directory, the
|
|
target directory gets removed, which has been corrected.
|
|
(merge 3e7d4888e5 tb/mingw-rmdir-symlink-to-directory later to maint).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
