1 Git v2.37 Release Notes
2 =======================
4 UI, Workflows & Features
6 * "vimdiff[123]" mergetool drivers have been reimplemented with a
7 more generic layout mechanism.
9 * "git -v" and "git -h" are now understood as "git --version" and
10 "git --help".
12 * The temporary files fed to external diff command are now generated
13 inside a new temporary directory under the same basename.
15 * "git log --since=X" will stop traversal upon seeing a commit that
16 is older than X, but there may be commits behind it that is younger
17 than X when the commit was created with a faulty clock. A new
18 option is added to keep digging without stopping, and instead
19 filter out commits with timestamp older than X.
21 * "git -c branch.autosetupmerge=simple branch $A $B" will set the $B
22 as $A's upstream only when $A and $B shares the same name, and "git
23 -c push.default=simple" on branch $A would push to update the
24 branch $A at the remote $B came from. Also more places use the
25 sole remote, if exists, before defaulting to 'origin'.
27 * A new doc has been added that lists tips for tools to work with
28 Git's codebase.
30 * "git remote -v" now shows the list-objects-filter used during
31 fetching from the remote, if available.
33 * With the new http.curloptResolve configuration, the CURLOPT_RESOLVE
34 mechanism that allows cURL based applications to use pre-resolved
35 IP addresses for the requests is exposed to the scripts.
37 * "git add -i" was rewritten in C some time ago and has been in
38 testing; the reimplementation is now exposed to general public by
39 default.
42 Performance, Internal Implementation, Development Support etc.
44 * The performance of the "untracked cache" feature has been improved
45 when "--untracked-files=<mode>" and "status.showUntrackedFiles"
46 are combined.
48 * "git stash" works better with sparse index entries.
50 * "git show :<path>" learned to work better with the sparse-index
51 feature.
53 * Introduce and apply coccinelle rule to discourage an explicit
54 comparison between a pointer and NULL, and applies the clean-up to
55 the maintenance track.
58 Fixes since v2.36
59 -----------------
61 * "git submodule update" without pathspec should silently skip an
62 uninitialized submodule, but it started to become noisy by mistake.
63 (merge 4f1ccef87c gc/submodule-update-part2 later to maint).
65 * "diff-tree --stdin" has been broken for about a year, but 2.36
66 release broke it even worse by breaking running the command with
67 <pathspec>, which in turn broke "gitk" and got noticed. This has
68 been corrected by aligning its behaviour to that of "log".
69 (merge f8781bfda3 jc/diff-tree-stdin-fix later to maint).
71 * Regression fix for 2.36 where "git name-rev" started to sometimes
72 reference strings after they are freed.
73 (merge 45a14f578e rs/name-rev-fix-free-after-use later to maint).
75 * "git show <commit1> <commit2>... -- <pathspec>" lost the pathspec
76 when showing the second and subsequent commits, which has been
77 corrected.
78 (merge 5cdb38458e jc/show-pathspec-fix later to maint).
80 * "git fast-export -- <pathspec>" lost the pathspec when showing the
81 second and subsequent commits, which has been corrected.
82 (merge d1c25272f5 rs/fast-export-pathspec-fix later to maint).
84 * "git format-patch <args> -- <pathspec>" lost the pathspec when
85 showing the second and subsequent commits, which has been
86 corrected.
87 (merge 91f8f7e46f rs/format-patch-pathspec-fix later to maint).
89 * "git clone --origin X" leaked piece of memory that held value read
90 from the clone.defaultRemoteName configuration variable, which has
91 been plugged.
92 (merge 6dfadc8981 jc/clone-remote-name-leak-fix later to maint).
94 * Get rid of a bogus and over-eager coccinelle rule.
95 (merge 08bdd3a185 jc/cocci-xstrdup-or-null-fix later to maint).
97 * The path taken by "git multi-pack-index" command from the end user
98 was compared with path internally prepared by the tool withut first
99 normalizing, which lead to duplicated paths not being noticed,
100 which has been corrected.
101 (merge 11f9e8de3d ds/midx-normalize-pathname-before-comparison later to maint).
103 * Correct choices of C compilers used in various CI jobs.
104 (merge 3506cae04f ab/cc-package-fixes later to maint).
106 * Various cleanups to "git p4".
107 (merge 4ff0108d9e jh/p4-various-fixups later to maint).
109 * The progress meter of "git blame" was showing incorrect numbers
110 when processing only parts of the file.
111 (merge e5f5d7d42e ea/progress-partial-blame later to maint).
113 * "git rebase --keep-base <upstream> <branch-to-rebase>" computed the
114 commit to rebase onto incorrectly, which has been corrected.
115 (merge 9e5ebe9668 ah/rebase-keep-base-fix later to maint).
117 * Fix a leak of FILE * in an error codepath.
118 (merge c0befa0c03 kt/commit-graph-plug-fp-leak-on-error later to maint).
120 * Avoid problems from interaction between malloc_check and address
121 sanitizer.
122 (merge 067109a5e7 pw/test-malloc-with-sanitize-address later to maint).
124 * The commit summary shown after making a commit is matched to what
125 is given in "git status" not to use the break-rewrite heuristics.
126 (merge 84792322ed rs/commit-summary-wo-break-rewrite later to maint).
128 * Update a few end-user facing messages around eol conversion.
129 (merge c970d30c2c ah/convert-warning-message later to maint).
131 * Trace2 documentation updates.
132 (merge a6c80c313c js/trace2-doc-fixes later to maint).
134 * Build procedure fixup.
135 (merge 1fbfd96f50 mg/detect-compiler-in-c-locale later to maint).
137 * "git pull" without "--recurse-submodules=<arg>" made
138 submodule.recurse take precedence over fetch.recurseSubmodules by
139 mistake, which has been corrected.
140 (merge 5819417365 gc/pull-recurse-submodules later to maint).
142 * "git bisect" was too silent before it is ready to start computing
143 the actual bisection, which has been corrected.
144 (merge f11046e6de cd/bisect-messages-from-pre-flight-states later to maint).
146 * macOS CI jobs have been occasionally flaky due to tentative version
147 skew between perforce and the homebrew packager. Instead of
148 failing the whole CI job, just let it skip the p4 tests when this
149 happens.
150 (merge f15e00b463 cb/ci-make-p4-optional later to maint).
152 * A bit of test framework fixes with a few fixes to issues found by
153 valgrind.
154 (merge 7c898554d7 ab/valgrind-fixes later to maint).
156 * "git archive --add-file=<path>" picked up the raw permission bits
157 from the path and propagated to zip output in some cases, without
158 normalization, which has been corrected (tar output did not have
159 this issue).
160 (merge 6a61661967 jc/archive-add-file-normalize-mode later to maint).
162 * "make coverage-report" without first running "make coverage" did
163 not produce any meaningful result, which has been corrected.
164 (merge 96ddfecc5b ep/coverage-report-wants-test-to-have-run later to maint).
166 * The "--current" option of "git show-branch" should have been made
167 incompatible with the "--reflog" mode, but this was not enforced,
168 which has been corrected.
169 (merge 41c64ae0e7 jc/show-branch-g-current later to maint).
171 * "git fetch" unnecessarily failed when an unexpected optional
172 section appeared in the output, which has been corrected.
173 (merge 7709acf7be jt/fetch-peek-optional-section later to maint).
175 * The way "git fetch" without "--update-head-ok" ensures that HEAD in
176 no worktree points at any ref being updated was too wasteful, which
177 has been optimized a bit.
178 (merge f7400da800 os/fetch-check-not-current-branch later to maint).
180 * "git fetch --recurse-submodules" from multiple remotes (either from
181 a remote group, or "--all") used to make one extra "git fetch" in
182 the submodules, which has been corrected.
183 (merge 0353c68818 jc/avoid-redundant-submodule-fetch later to maint).
185 * With a recent update to refuse access to repositories of other
186 people by default, "sudo make install" and "sudo git describe"
187 stopped working. This series intends to loosen it while keeping
188 the safety.
189 (merge b9063afda1 cb/path-owner-check-with-sudo later to maint).
191 * The tests that ensured merges stop when interfering local changes
192 are present did not make sure that local changes are preserved; now
193 they do.
194 (merge 4b317450ce jc/t6424-failing-merge-preserve-local-changes later to maint).
196 * Some real problems noticed by gcc 12 have been fixed, while false
197 positives have been worked around.
199 * Other code cleanup, docfix, build fix, etc.
