Git 2.32 Release Notes
|
|
======================
|
|
|
|
Backward compatibility notes
|
|
----------------------------
|
|
|
|
* ".gitattributes", ".gitignore", and ".mailmap" files that are
|
|
symbolic links are ignored.
|
|
|
|
|
|
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.
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
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.
|
|
(merge 097ea2c848 jh/fsmonitor-prework later to maint).
|
|
|
|
* The data structure used by fsmonitor interface was not properly
|
|
duplicated during an in-core merge, leading to use-after-free etc.
|
|
(merge 4abc57848d js/fsmonitor-unpack-fix later to maint).
|
|
|
|
* "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.
|
|
(merge 7730f85594 jk/bisect-peel-tag-fix later to maint).
|
|
|
|
* Fix macros that can silently inject unintended null-statements.
|
|
(merge 116affac3f rs/avoid-null-statement-after-macro-call later to maint).
|
|
|
|
* CALLOC_ARRAY() macro replaces many uses of xcalloc().
|
|
(merge 1c57cc70ec rs/calloc-array later to maint).
|
|
|
|
* Update insn in Makefile comments to run fuzz-all target.
|
|
(merge 68b5c3aa48 ah/make-fuzz-all-doc-update later to maint).
|
|
|
|
* Fix a corner case bug in "git mv" on case insensitive systems,
|
|
which was introduced in 2.29 timeframe.
|
|
(merge 93c3d297b5 tb/git-mv-icase-fix later to maint).
|
|
|
|
* 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).
|
|
|
|
* Other code cleanup, docfix, build fix, etc.
|
|
(merge 486f4bd183 jc/calloc-fix later to maint).
|
|
(merge 5f70859c15 jt/clone-unborn-head later to maint).
|
|
(merge cfd409ed09 km/config-doc-typofix later to maint).
|
