1 Git 2.32 Release Notes
2 ======================
4 Backward compatibility notes
5 ----------------------------
7 * ".gitattributes", ".gitignore", and ".mailmap" files that are
8 symbolic links are ignored.
11 Updates since v2.31
12 -------------------
14 UI, Workflows & Features
16 * It does not make sense to make ".gitattributes", ".gitignore" and
17 ".mailmap" symlinks, as they are supposed to be usable from the
18 object store (think: bare repositories where HEAD:.mailmap etc. are
19 used). When these files are symbolic links, we used to read the
20 contents of the files pointed by them by mistake, which has been
21 corrected.
23 * "git stash show" learned to optionally show untracked part of the
24 stash.
26 * "git log --format='...'" learned "%(describe)" placeholder.
28 * "git repack" so far has been only capable of repacking everything
29 under the sun into a single pack (or split by size). A cleverer
30 strategy to reduce the cost of repacking a repository has been
31 introduced.
33 * The http codepath learned to let the credential layer to cache the
34 password used to unlock a certificate that has successfully been
35 used.
37 * "git commit --fixup=<commit>", which was to tweak the changes made
38 to the contents while keeping the original log message intact,
39 learned "--fixup=(amend|reword):<commit>", that can be used to
40 tweak both the message and the contents, and only the message,
41 respectively.
44 Performance, Internal Implementation, Development Support etc.
46 * Rename detection rework continues.
48 * GIT_TEST_FAIL_PREREQS is a mechanism to skip test pieces with
49 prerequisites to catch broken tests that depend on the side effects
50 of optional pieces, but did not work at all when negative
51 prerequisites were involved.
52 (merge 27d578d904 jk/fail-prereq-testfix later to maint).
54 * "git diff-index" codepath has been taught to trust fsmonitor status
55 to reduce number of lstat() calls.
56 (merge 7e5aa13d2c nk/diff-index-fsmonitor later to maint).
58 * Reorganize Makefile to allow building git.o and other essential
59 objects without extra stuff needed only for testing.
63 Fixes since v2.31
64 -----------------
66 * The fsmonitor interface read from its input without making sure
67 there is something to read from. This bug is new in 2.31
68 timeframe.
69 (merge 097ea2c848 jh/fsmonitor-prework later to maint).
71 * The data structure used by fsmonitor interface was not properly
72 duplicated during an in-core merge, leading to use-after-free etc.
73 (merge 4abc57848d js/fsmonitor-unpack-fix later to maint).
75 * "git bisect" reimplemented more in C during 2.30 timeframe did not
76 take an annotated tag as a good/bad endpoint well. This regression
77 has been corrected.
78 (merge 7730f85594 jk/bisect-peel-tag-fix later to maint).
80 * Fix macros that can silently inject unintended null-statements.
81 (merge 116affac3f rs/avoid-null-statement-after-macro-call later to maint).
83 * CALLOC_ARRAY() macro replaces many uses of xcalloc().
84 (merge 1c57cc70ec rs/calloc-array later to maint).
86 * Update insn in Makefile comments to run fuzz-all target.
87 (merge 68b5c3aa48 ah/make-fuzz-all-doc-update later to maint).
89 * Fix a corner case bug in "git mv" on case insensitive systems,
90 which was introduced in 2.29 timeframe.
91 (merge 93c3d297b5 tb/git-mv-icase-fix later to maint).
93 * We had a code to diagnose and die cleanly when a required
94 clean/smudge filter is missing, but an assert before that
95 unnecessarily fired, hiding the end-user facing die() message.
96 (merge 6fab35f748 mt/cleanly-die-upon-missing-required-filter later to maint).
98 * Update C code that sets a few configuration variables when a remote
99 is configured so that it spells configuration variable names in the
100 canonical camelCase.
101 (merge 0f1da600e6 ab/remote-write-config-in-camel-case later to maint).
103 * A new configuration variable has been introduced to allow choosing
104 which version of the generation number gets used in the
105 commit-graph file.
106 (merge 702110aac6 ds/commit-graph-generation-config later to maint).
108 * Perf test update to work better in secondary worktrees.
109 (merge 36e834abc1 jk/perf-in-worktrees later to maint).
111 * Updates to memory allocation code around the use of pcre2 library.
112 (merge c1760352e0 ab/grep-pcre2-allocfix later to maint).
114 * "git -c core.bare=false clone --bare ..." would have segfaulted,
115 which has been corrected.
116 (merge 75555676ad bc/clone-bare-with-conflicting-config later to maint).
118 * Other code cleanup, docfix, build fix, etc.
119 (merge 486f4bd183 jc/calloc-fix later to maint).
120 (merge 5f70859c15 jt/clone-unborn-head later to maint).
121 (merge cfd409ed09 km/config-doc-typofix later to maint).
122 (merge 8588aa8657 jk/slimmed-down later to maint).
123 (merge 241b5d3ebe rs/xcalloc-takes-nelem-first later to maint).
124 (merge f451960708 dl/cat-file-doc-cleanup later to maint).
125 (merge 12604a8d0c sv/t9801-test-path-is-file-cleanup later to maint).
126 (merge ea7e63921c jr/doc-ignore-typofix later to maint).
127 (merge 23c781f173 ps/update-ref-trans-hook-doc later to maint).
