1 Git v2.39 Release Notes
2 =======================
4 UI, Workflows & Features
5 ------------------------
7 * "git grep" learned to expand the sparse-index more lazily and on
8 demand in a sparse checkout.
10 * By default, use of fsmonitor on a repository on networked
11 filesystem is disabled. Add knobs to make it workable on macOS.
13 * After checking out a "branch" that is a symbolic-ref that points at
14 another branch, "git symbolic-ref HEAD" reports the underlying
15 branch, not the symbolic-ref the user gave checkout as argument.
16 The command learned the "--no-recurse" option to stop after
17 dereferencing a symbolic-ref only once.
19 * "git branch --edit-description @{-1}" is now a way to edit branch
20 description of the branch you were on before switching to the
21 current branch.
24 Performance, Internal Implementation, Development Support etc.
25 --------------------------------------------------------------
27 * With a bit of header twiddling, use the native regexp library on
28 macOS instead of the compat/ one.
30 * Prepare for GNU [ef]grep that throw warning of their uses.
32 * Sources related to fuzz testing have been moved down to their own
33 directory.
35 * Most credential helpers ignored unknown entries in a credential
36 description, but a few died upon seeing them. The latter were
37 taught to ignore them, too
39 * "scalar unregister" in a repository that is already been
40 unregistered reported an error.
42 * Remove error detection from a function that fetches from promisor
43 remotes, and make it die when such a fetch fails to bring all the
44 requested objects, to give an early failure to various operations.
46 * Update CodingGuidelines to clarify what features to use and avoid
47 in C99.
48 (merge 438c2f859b ab/coding-guidelines-c99 later to maint).
50 * Avoid false-positive from LSan whose assumption may be broken with
51 higher optimization levels.
54 Fixes since v2.38
55 -----------------
57 * The codepath that reads from the index v4 had unaligned memory
58 accesses, which has been corrected.
59 (merge 4a6ed30f96 vd/fix-unaligned-read-index-v4 later to maint).
61 * Fix messages incorrectly marked for translation.
62 (merge 02cb8b9ee3 ah/fsmonitor-daemon-usage-non-l10n later to maint).
64 * "git fsck" failed to release contents of tree objects already used
65 from the memory, which has been fixed.
66 (merge 51b27747e5 jk/fsck-on-diet later to maint).
68 * "git clone" did not like to see the "--bare" and the "--origin"
69 options used together without a good reason.
70 (merge 3b910d6e29 jk/clone-allow-bare-and-o-together later to maint).
72 * "git remote rename" failed to rename a remote without fetch
73 refspec, which has been corrected.
74 (merge 5a97b38109 jk/remote-rename-without-fetch-refspec later to maint).
76 * Documentation on various Boolean GIT_* environment variables have
77 been clarified.
78 (merge 819fb68222 jc/environ-docs later to maint).
80 * "git rebase -i" can mistakenly attempt to apply a fixup to a commit
81 itself, which has been corrected.
82 (merge 3e367a5f2f ja/rebase-i-avoid-amending-self later to maint).
84 * "git multi-pack-index repack/expire" used to repack unreachable
85 cruft into a new pack, which have been corrected.
86 (merge b62ad5681f tb/midx-repack-ignore-cruft-packs later to maint).
88 * In read-only repositories, "git merge-tree" tried to come up with a
89 merge result tree object, which it failed (which is not wrong) and
90 led to a segfault (which is bad), which has been corrected.
91 (merge 92481d1b26 js/merge-ort-in-read-only-repo later to maint).
93 * Force C locale while running tests around httpd to make sure we can
94 find expected error messages in the log.
95 (merge 7a2d8ea47e rs/test-httpd-in-C-locale later to maint).
97 * Fix a logic in "mailinfo -b" that miscomputed the length of a
98 substring, which lead to an out-of-bounds access.
99 (merge 3ef1494685 pw/mailinfo-b-fix later to maint).
101 * The codepath to sign learned to report errors when it fails to read
102 from "ssh-keygen".
103 (merge 36fb0d07d8 pw/ssh-sign-report-errors later to maint).
105 * Code clean-up that results in plugging a leak.
106 (merge 246526d019 rs/bisect-start-leakfix later to maint).
108 * "GIT_EDITOR=: git branch --edit-description" resulted in failure,
109 which has been corrected.
110 (merge e288b3de35 jc/branch-description-unset later to maint).
112 * The code to clean temporary object directories (used for
113 quarantine) tried to remove them inside its signal handler, which
114 was a no-no.
115 (merge 22613b25ec jc/tmp-objdir later to maint).
117 * Update comment in the Makefile about the RUNTIME_PREFIX config knob.
118 (merge ebb6c16607 dd/document-runtime-prefix-better later to maint).
120 * Clarify that "the sentence after <area>: prefix does not begin with
121 a capital letter" rule applies only to the commit title.
122 (merge 3991bb73dd jc/use-of-uc-in-log-messages later to maint).
124 * "git branch --edit-description" on an unborh branch misleadingly
125 said that no such branch exists, which has been corrected.
126 (merge bcfc82bd48 rj/branch-edit-desc-unborn later to maint).
128 * Work around older clang that warns against C99 zero initialization
129 syntax for struct.
130 (merge 54795d37d9 jh/struct-zero-init-with-older-clang later to maint).
132 * Giving "--invert-grep" and "--all-match" without "--grep" to the
133 "git log" command resulted in an attempt to access grep pattern
134 expression structure that has not been allocated, which has been
135 corrected.
136 (merge db84376f98 ab/grep-simplify-extended-expression later to maint).
138 * Other code cleanup, docfix, build fix, etc.
