Git 2.32 Release Notes
|
|
======================
|
|
|
|
Backward compatibility notes
|
|
----------------------------
|
|
|
|
* ".gitattributes", ".gitignore", and ".mailmap" files that are
|
|
symbolic links are ignored.
|
|
|
|
* "git apply --3way" used to first attempt a straight application,
|
|
and only fell back to the 3-way merge algorithm when the stright
|
|
application failed. Starting with this version, the command will
|
|
first try the 3-way merge algorithm and only when it fails (either
|
|
resulting with conflict or the base versions of blobs are missing),
|
|
falls back to the usual patch application.
|
|
|
|
|
|
Updates since v2.31
|
|
-------------------
|
|
|
|
UI, Workflows & Features
|
|
|
|
* It does not make sense to make ".gitattributes", ".gitignore" and
|
|
".mailmap" symlinks, as they are supposed to be usable from the
|
|
object store (think: bare repositories where HEAD:.mailmap etc. are
|
|
used). When these files are symbolic links, we used to read the
|
|
contents of the files pointed by them by mistake, which has been
|
|
corrected.
|
|
|
|
* "git stash show" learned to optionally show untracked part of the
|
|
stash.
|
|
|
|
* "git log --format='...'" learned "%(describe)" placeholder.
|
|
|
|
* "git repack" so far has been only capable of repacking everything
|
|
under the sun into a single pack (or split by size). A cleverer
|
|
strategy to reduce the cost of repacking a repository has been
|
|
introduced.
|
|
|
|
* The http codepath learned to let the credential layer to cache the
|
|
password used to unlock a certificate that has successfully been
|
|
used.
|
|
|
|
* "git commit --fixup=<commit>", which was to tweak the changes made
|
|
to the contents while keeping the original log message intact,
|
|
learned "--fixup=(amend|reword):<commit>", that can be used to
|
|
tweak both the message and the contents, and only the message,
|
|
respectively.
|
|
|
|
* "git send-email" learned to honor the core.hooksPath configuration.
|
|
|
|
* "git format-patch -v<n>" learned to allow a reroll count that is
|
|
not an integer.
|
|
|
|
* "git commit" learned "--trailer <key>[=<value>]" option; together
|
|
with the interpret-trailers command, this will make it easier to
|
|
support custom trailers.
|
|
|
|
* "git clone --reject-shallow" option fails the clone as soon as we
|
|
notice that we are cloning from a shallow repository.
|
|
|
|
* A configuration variable has been added to force tips of certain
|
|
refs to be given a reachability bitmap.
|
|
|
|
* "gitweb" learned "e-mail privacy" feature to redact strings that
|
|
look like e-mail addresses on various pages.
|
|
|
|
* "git apply --3way" has always been "to fall back to 3-way merge
|
|
only when straight application fails". Swap the order of falling
|
|
back so that 3-way is always attempted first (only when the option
|
|
is given, of course) and then straight patch application is used as
|
|
a fallback when it fails.
|
|
|
|
* "git apply" now takes "--3way" and "--cached" at the same time, and
|
|
work and record results only in the index.
|
|
|
|
* The command line completion (in contrib/) has learned that
|
|
CHERRY_PICK_HEAD is a possible pseudo-ref.
|
|
|
|
* Userdiff patterns for "Scheme" has been added.
|
|
|
|
* "git log" learned "--diff-merges=<style>" option, with an
|
|
associated configuration variable log.diffMerges.
|
|
|
|
* "git log --format=..." placeholders learned %ah/%ch placeholders to
|
|
request the --date=human output.
|
|
|
|
* Replace GIT_CONFIG_NOSYSTEM mechanism to decline from reading the
|
|
system-wide configuration file with GIT_CONFIG_SYSTEM that lets
|
|
users specify from which file to read the system-wide configuration
|
|
(setting it to an empty file would essentially be the same as
|
|
setting NOSYSTEM), and introduce GIT_CONFIG_GLOBAL to override the
|
|
per-user configuration in $HOME/.gitconfig.
|
|
|
|
* "git add" and "git rm" learned not to touch those paths that are
|
|
outside of sparse checkout.
|
|
|
|
* "git rev-list" learns the "--filter=object:type=<type>" option,
|
|
which can be used to exclude objects of the given kind from the
|
|
packfile generated by pack-objects.
|
|
|
|
* The command line completion (in contrib/) for "git stash" has been
|
|
updated.
|
|
|
|
* "git subtree" updates.
|
|
|
|
* It is now documented that "format-patch" skips merges.
|
|
|
|
* Options to "git pack-objects" that take numeric values like
|
|
--window and --depth should not accept negative values; the input
|
|
validation has been tightened.
|
|
|
|
* The way the command line specified by the trailer.<token>.command
|
|
configuration variable receives the end-user supplied value was
|
|
both error prone and misleading. An alternative to achieve the
|
|
same goal in a safer and more intuitive way has been added, as
|
|
the trailer.<token>.cmd configuration variable, to replace it.
|
|
|
|
* "git add -i --dry-run" does not dry-run, which was surprising. The
|
|
combination of options has taught to error out.
|
|
|
|
* "git push" learns to discover common ancestor with the receiving
|
|
end over protocol v2. This will hopefully make "git push" as
|
|
efficient as "git fetch" in avoiding objects from getting
|
|
transferred unnecessarily.
|
|
|
|
* "git mailinfo" (hence "git am") learned the "--quoted-cr" option to
|
|
control how lines ending with CRLF wrapped in base64 or qp are
|
|
handled.
|
|
|
|
|
|
Performance, Internal Implementation, Development Support etc.
|
|
|
|
* Rename detection rework continues.
|
|
|
|
* GIT_TEST_FAIL_PREREQS is a mechanism to skip test pieces with
|
|
prerequisites to catch broken tests that depend on the side effects
|
|
of optional pieces, but did not work at all when negative
|
|
prerequisites were involved.
|
|
(merge 27d578d904 jk/fail-prereq-testfix later to maint).
|
|
|
|
* "git diff-index" codepath has been taught to trust fsmonitor status
|
|
to reduce number of lstat() calls.
|
|
(merge 7e5aa13d2c nk/diff-index-fsmonitor later to maint).
|
|
|
|
* Reorganize Makefile to allow building git.o and other essential
|
|
objects without extra stuff needed only for testing.
|
|
|
|
* Preparatory API changes for parallel checkout.
|
|
|
|
* A simple IPC interface gets introduced to build services like
|
|
fsmonitor on top.
|
|
|
|
* Fsck API clean-up.
|
|
|
|
* SECURITY.md that is facing individual contributors and end users
|
|
has been introduced. Also a procedure to follow when preparing
|
|
embargoed releases has been spelled out.
|
|
(merge 09420b7648 js/security-md later to maint).
|
|
|
|
* Optimize "rev-list --use-bitmap-index --objects" corner case that
|
|
uses negative tags as the stopping points.
|
|
|
|
* CMake update for vsbuild.
|
|
|
|
* An on-disk reverse-index to map the in-pack location of an object
|
|
back to its object name across multiple packfiles is introduced.
|
|
|
|
* Generate [ec]tags under $(QUIET_GEN).
|
|
|
|
* Clean-up codepaths that implements "git send-email --validate"
|
|
option and improves the message from it.
|
|
|
|
* The last remnant of gettext-poison has been removed.
|
|
|
|
* The test framework has been taught to optionally turn the default
|
|
merge strategy to "ort" throughout the system where we use
|
|
three-way merges internally, like cherry-pick, rebase etc.,
|
|
primarily to enhance its test coverage (the strategy has been
|
|
available as an explicit "-s ort" choice).
|
|
|
|
* A bit of code clean-up and a lot of test clean-up around userdiff
|
|
area.
|
|
|
|
* Handling of "promisor packs" that allows certain objects to be
|
|
missing and lazily retrievable has been optimized (a bit).
|
|
|
|
* When packet_write() fails, we gave an extra error message
|
|
unnecessarily, which has been corrected.
|
|
|
|
* The checkout machinery has been taught to perform the actual
|
|
write-out of the files in parallel when able.
|
|
|
|
* Show errno in the trace output in the error codepath that calls
|
|
read_raw_ref method.
|
|
|
|
* Effort to make the command line completion (in contrib/) safe with
|
|
"set -u" continues.
|
|
|
|
* Tweak a few tests for "log --format=..." that show timestamps in
|
|
various formats.
|
|
|
|
* The reflog expiry machinery has been taught to emit trace events.
|
|
|
|
* Over-the-wire protocol learns a new request type to ask for object
|
|
sizes given a list of object names.
|
|
|
|
|
|
Fixes since v2.31
|
|
-----------------
|
|
|
|
* The fsmonitor interface read from its input without making sure
|
|
there is something to read from. This bug is new in 2.31
|
|
timeframe.
|
|
|
|
* The data structure used by fsmonitor interface was not properly
|
|
duplicated during an in-core merge, leading to use-after-free etc.
|
|
|
|
* "git bisect" reimplemented more in C during 2.30 timeframe did not
|
|
take an annotated tag as a good/bad endpoint well. This regression
|
|
has been corrected.
|
|
|
|
* Fix macros that can silently inject unintended null-statements.
|
|
|
|
* CALLOC_ARRAY() macro replaces many uses of xcalloc().
|
|
|
|
* Update insn in Makefile comments to run fuzz-all target.
|
|
|
|
* Fix a corner case bug in "git mv" on case insensitive systems,
|
|
which was introduced in 2.29 timeframe.
|
|
|
|
* We had a code to diagnose and die cleanly when a required
|
|
clean/smudge filter is missing, but an assert before that
|
|
unnecessarily fired, hiding the end-user facing die() message.
|
|
(merge 6fab35f748 mt/cleanly-die-upon-missing-required-filter later to maint).
|
|
|
|
* Update C code that sets a few configuration variables when a remote
|
|
is configured so that it spells configuration variable names in the
|
|
canonical camelCase.
|
|
(merge 0f1da600e6 ab/remote-write-config-in-camel-case later to maint).
|
|
|
|
* A new configuration variable has been introduced to allow choosing
|
|
which version of the generation number gets used in the
|
|
commit-graph file.
|
|
(merge 702110aac6 ds/commit-graph-generation-config later to maint).
|
|
|
|
* Perf test update to work better in secondary worktrees.
|
|
(merge 36e834abc1 jk/perf-in-worktrees later to maint).
|
|
|
|
* Updates to memory allocation code around the use of pcre2 library.
|
|
(merge c1760352e0 ab/grep-pcre2-allocfix later to maint).
|
|
|
|
* "git -c core.bare=false clone --bare ..." would have segfaulted,
|
|
which has been corrected.
|
|
(merge 75555676ad bc/clone-bare-with-conflicting-config later to maint).
|
|
|
|
* When "git checkout" removes a path that does not exist in the
|
|
commit it is checking out, it wasn't careful enough not to follow
|
|
symbolic links, which has been corrected.
|
|
(merge fab78a0c3d mt/checkout-remove-nofollow later to maint).
|
|
|
|
* A few option description strings started with capital letters,
|
|
which were corrected.
|
|
(merge 5ee90326dc cc/downcase-opt-help later to maint).
|
|
|
|
* Plug or annotate remaining leaks that trigger while running the
|
|
very basic set of tests.
|
|
(merge 68ffe095a2 ah/plugleaks later to maint).
|
|
|
|
* The hashwrite() API uses a buffering mechanism to avoid calling
|
|
write(2) too frequently. This logic has been refactored to be
|
|
easier to understand.
|
|
(merge ddaf1f62e3 ds/clarify-hashwrite later to maint).
|
|
|
|
* "git cherry-pick/revert" with or without "--[no-]edit" did not spawn
|
|
the editor as expected (e.g. "revert --no-edit" after a conflict
|
|
still asked to edit the message), which has been corrected.
|
|
(merge 39edfd5cbc en/sequencer-edit-upon-conflict-fix later to maint).
|
|
|
|
* "git daemon" has been tightened against systems that take backslash
|
|
as directory separator.
|
|
(merge 9a7f1ce8b7 rs/daemon-sanitize-dir-sep later to maint).
|
|
|
|
* A NULL-dereference bug has been corrected in an error codepath in
|
|
"git for-each-ref", "git branch --list" etc.
|
|
(merge c685450880 jk/ref-filter-segfault-fix later to maint).
|
|
|
|
* Streamline the codepath to fix the UTF-8 encoding issues in the
|
|
argv[] and the prefix on macOS.
|
|
(merge c7d0e61016 tb/precompose-prefix-simplify later to maint).
|
|
|
|
* The command-line completion script (in contrib/) had a couple of
|
|
references that would have given a warning under the "-u" (nounset)
|
|
option.
|
|
(merge c5c0548d79 vs/completion-with-set-u later to maint).
|
|
|
|
* When "git pack-objects" makes a literal copy of a part of existing
|
|
packfile using the reachability bitmaps, its update to the progress
|
|
meter was broken.
|
|
(merge 8e118e8490 jk/pack-objects-bitmap-progress-fix later to maint).
|
|
|
|
* The dependencies for config-list.h and command-list.h were broken
|
|
when the former was split out of the latter, which has been
|
|
corrected.
|
|
(merge 56550ea718 sg/bugreport-fixes later to maint).
|
|
|
|
* "git push --quiet --set-upstream" was not quiet when setting the
|
|
upstream branch configuration, which has been corrected.
|
|
(merge f3cce896a8 ow/push-quiet-set-upstream later to maint).
|
|
|
|
* The prefetch task in "git maintenance" assumed that "git fetch"
|
|
from any remote would fetch all its local branches, which would
|
|
fetch too much if the user is interested in only a subset of
|
|
branches there.
|
|
(merge 32f67888d8 ds/maintenance-prefetch-fix later to maint).
|
|
|
|
* Clarify that pathnames recorded in Git trees are most often (but
|
|
not necessarily) encoded in UTF-8.
|
|
(merge 9364bf465d ab/pathname-encoding-doc later to maint).
|
|
|
|
* "git --config-env var=val cmd" weren't accepted (only
|
|
--config-env=var=val was).
|
|
(merge c331551ccf ps/config-env-option-with-separate-value later to maint).
|
|
|
|
* When the reachability bitmap is in effect, the "do not lose
|
|
recently created objects and those that are reachable from them"
|
|
safety to protect us from races were disabled by mistake, which has
|
|
been corrected.
|
|
(merge 2ba582ba4c jk/prune-with-bitmap-fix later to maint).
|
|
|
|
* Cygwin pathname handling fix.
|
|
(merge bccc37fdc7 ad/cygwin-no-backslashes-in-paths later to maint).
|
|
|
|
* "git rebase --[no-]reschedule-failed-exec" did not work well with
|
|
its configuration variable, which has been corrected.
|
|
(merge e5b32bffd1 ab/rebase-no-reschedule-failed-exec later to maint).
|
|
|
|
* Portability fix for command line completion script (in contrib/).
|
|
(merge f2acf763e2 si/zsh-complete-comment-fix later to maint).
|
|
|
|
* "git repack -A -d" in a partial clone unnecessarily loosened
|
|
objects in promisor pack.
|
|
|
|
* "git bisect skip" when custom words are used for new/old did not
|
|
work, which has been corrected.
|
|
|
|
* A few variants of informational message "Already up-to-date" has
|
|
been rephrased.
|
|
(merge ad9322da03 js/merge-already-up-to-date-message-reword later to maint).
|
|
|
|
* "git submodule update --quiet" did not propagate the quiet option
|
|
down to underlying "git fetch", which has been corrected.
|
|
(merge 62af4bdd42 nc/submodule-update-quiet later to maint).
|
|
|
|
* Document that our test can use "local" keyword.
|
|
(merge a84fd3bcc6 jc/test-allows-local later to maint).
|
|
|
|
* The word-diff mode has been taught to work better with a word
|
|
regexp that can match an empty string.
|
|
(merge 0324e8fc6b pw/word-diff-zero-width-matches later to maint).
|
|
|
|
* "git p4" learned to find branch points more efficiently.
|
|
(merge 6b79818bfb jk/p4-locate-branch-point-optim later to maint).
|
|
|
|
* When "git update-ref -d" removes a ref that is packed, it left
|
|
empty directories under $GIT_DIR/refs/ for
|
|
(merge 5f03e5126d wc/packed-ref-removal-cleanup later to maint).
|
|
|
|
* "git clean" and "git ls-files -i" had confusion around working on
|
|
or showing ignored paths inside an ignored directory, which has
|
|
been corrected.
|
|
(merge b548f0f156 en/dir-traversal later to maint).
|
|
|
|
* The handling of "%(push)" formatting element of "for-each-ref" and
|
|
friends was broken when the same codepath started handling
|
|
"%(push:<what>)", which has been corrected.
|
|
(merge 1e1c4c5eac zh/ref-filter-push-remote-fix later to maint).
|
|
|
|
* The bash prompt script (in contrib/) did not work under "set -u".
|
|
(merge 5c0cbdb107 en/prompt-under-set-u later to maint).
|
|
|
|
* The "chainlint" feature in the test framework is a handy way to
|
|
catch common mistakes in writing new tests, but tends to get
|
|
expensive. An knob to selectively disable it has been introduced
|
|
to help running tests that the developer has not modified.
|
|
(merge 2d86a96220 jk/test-chainlint-softer later to maint).
|
|
|
|
* The "rev-parse" command did not diagnose the lack of argument to
|
|
"--path-format" option, which was introduced in v2.31 era, which
|
|
has been corrected.
|
|
(merge 99fc555188 wm/rev-parse-path-format-wo-arg later to maint).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
