4Updates since Git 2.34
5----------------------
6
7Backward compatibility warts
8
9 * "_" is now treated as any other URL-valid characters in an URL when
10 matching the per-URL configuration variable names.
11
12 * The color palette used by "git grep" has been updated to match that
13 of GNU grep.
14
15
16Note to those who build from the source
17
18 * You may need to define NO_UNCOMPRESS2 Makefile macro if you build
19 with zlib older than 1.2.9.
20
21 * If your compiler cannot grok C99, the build will fail. See the
22 instruction at the beginning of git-compat-util.h if this happens
23 to you.
24
25
26UI, Workflows & Features
27
28 * "git status --porcelain=v2" now show the number of stash entries
29 with --show-stash like the normal output does.
30
31 * "git stash" learned the "--staged" option to stash away what has
32 been added to the index (and nothing else).
33
34 * "git var GIT_DEFAULT_BRANCH" is a way to see what name is used for
35 the newly created branch if "git init" is run.
36
37 * Various operating modes of "git reset" have been made to work
38 better with the sparse index.
39
40 * "git submodule deinit" for a submodule whose .git metadata
41 directory is embedded in its working tree refused to work, until
42 the submodule gets converted to use the "absorbed" form where the
43 metadata directory is stored in superproject, and a gitfile at the
44 top-level of the working tree of the submodule points at it. The
45 command is taught to convert such submodules to the absorbed form
46 as needed.
47
48 * The completion script (in contrib/) learns that the "--date"
49 option of commands from the "git log" family takes "human" and
50 "auto" as valid values.
51
52 * "Zealous diff3" style of merge conflict presentation has been added.
53
54 * The "git log --format=%(describe)" placeholder has been extended to
55 allow passing selected command-line options to the underlying "git
56 describe" command.
57
58 * "default" and "reset" have been added to our color palette.
59
60 * The cryptographic signing using ssh keys can specify literal keys
61 for keytypes whose name do not begin with the "ssh-" prefix by
62 using the "key::" prefix mechanism (e.g. "key::ecdsa-sha2-nistp256").
63
64 * "git fetch" without the "--update-head-ok" option ought to protect
65 a checked out branch from getting updated, to prevent the working
66 tree that checks it out to go out of sync. The code was written
67 before the use of "git worktree" got widespread, and only checked
68 the branch that was checked out in the current worktree, which has
69 been updated.
70
71 * "git name-rev" has been tweaked to give output that is shorter and
72 easier to understand.
73
74 * "git apply" has been taught to ignore a message without a patch
75 with the "--allow-empty" option. It also learned to honor the
76 "--quiet" option given from the command line.
77
78 * The "init" and "set" subcommands in "git sparse-checkout" have been
79 unified for a better user experience and performance.
80
81 * Many git commands that deal with working tree files try to remove a
82 directory that becomes empty (i.e. "git switch" from a branch that
83 has the directory to another branch that does not would attempt
84 remove all files in the directory and the directory itself). This
85 drops users into an unfamiliar situation if the command was run in
86 a subdirectory that becomes subject to removal due to the command.
87 The commands have been taught to keep an empty directory if it is
88 the directory they were started in to avoid surprising users.
89
90 * "git am" learns "--empty=(stop|drop|keep)" option to tweak what is
91 done to a piece of e-mail without a patch in it.
92
93 * The default merge message prepared by "git merge" records the name
94 of the current branch; the name can be overridden with a new option
95 to allow users to pretend a merge is made on a different branch.
96
97 * The way "git p4" shows file sizes in its output has been updated to
98 use human-readable units.
99
100 * "git -c branch.autosetupmerge=inherit branch new old" makes "new"
101 to have the same upstream as the "old" branch, instead of marking
102 "old" itself as its upstream.
103
104
105Performance, Internal Implementation, Development Support etc.
106
107 * The use of errno as a means to carry the nature of error in the ref
108 API implementation has been reworked and reduced.
109
110 * Teach and encourage first-time contributors to this project to
111 state the base commit when they submit their topic.
112
113 * The command line completion for "git send-email" options have been
114 tweaked to make it easier to keep it in sync with the command itself.
115
116 * Ensure that the sparseness of the in-core index matches the
117 index.sparse configuration specified by the repository immediately
118 after the on-disk index file is read.
119
120 * Code clean-up to eventually allow information on remotes defined
121 for an arbitrary repository to be read.
122
123 * Build optimization.
124
125 * Tighten code for testing pack-bitmap.
126
127 * Weather balloon to break people with compilers that do not support
128 C99.
129
130 * The "reftable" backend for the refs API, without integrating into
131 the refs subsystem, has been added.
132
133 * More tests are marked as leak-free.
134
135 * The test framework learns to list unsatisfied test prerequisites,
136 and optionally error out when prerequisites that are expected to be
137 satisfied are not.
138
139 * The default setting for trace2 event nesting was too low to cause
140 test failures, which is worked around by bumping it up in the test
141 framework.
142
143 * Drop support for TravisCI and update test workflows at GitHub.
144
145 * Many tests that used to need GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME
146 mechanism to force "git" to use 'master' as the default name for
147 the initial branch no longer need it; the use of the mechanism from
148 them have been removed.
149
150 * Allow running our tests while disabling fsync.
151
152 * Document the parameters given to the reflog entry iterator callback
153 functions.
154 (merge e6e94f34b2 jc/reflog-iterator-callback-doc later to maint).
155
156 * The test helper for refs subsystem learned to write bogus and/or
157 nonexistent object name to refs to simulate error situations we
158 want to test Git in.
159
160 * "diff --histogram" optimization.
161
162 * Weather balloon to find compilers that do not grok variable
163 declaration in the for() loop.
164
165 * diff and blame commands have been taught to work better with sparse
166 index.
167
168 * The chainlint test script linter in the test suite has been updated.
169
170 * The DEVELOPER=yes build uses -std=gnu99 now.
171
172 * "git format-patch" uses a single rev_info instance and then exits.
173 Mark the structure with UNLEAK() macro to squelch leak sanitizer.
174
175 * New interface into the tmp-objdir API to help in-core use of the
176 quarantine feature.
177
178 * Broken &&-chains in the test scripts have been corrected.
179
180 * The RCS keyword substitution in "git p4" used to be done assuming
181 that the contents are UTF-8 text, which can trigger decoding
182 errors. We now treat the contents as a bytestring for robustness
183 and correctness.
184
185 * The conditions to choose different definitions of the FLEX_ARRAY
186 macro for vendor compilers has been simplified to make it easier to
187 maintain.
188
189 * Correctness and performance update to "diff --color-moved" feature.
190
191 * "git upload-pack" (the other side of "git fetch") used a 8kB buffer
192 but most of its payload came on 64kB "packets". The buffer size
193 has been enlarged so that such a packet fits.
194
195 * "git fetch" and "git pull" are now declared sparse-index clean.
196 Also "git ls-files" learns the "--sparse" option to help debugging.
197
198 * Similar message templates have been consolidated so that
199 translators need to work on fewer number of messages.
200
201
202Fixes since v2.34
203-----------------
204
205 * "git grep" looking in a blob that has non-UTF8 payload was
206 completely broken when linked with certain versions of PCREv2
207 library in the latest release.
208
209 * Other code cleanup, docfix, build fix, etc.
210
211 * "git pull" with any strategy when the other side is behind us
212 should succeed as it is a no-op, but doesn't.
213
214 * An earlier change in 2.34.0 caused JGit application (that abused
215 GIT_EDITOR mechanism when invoking "git config") to get stuck with
216 a SIGTTOU signal; it has been reverted.
217
218 * An earlier change that broke .gitignore matching has been reverted.
219
220 * Things like "git -c branch.sort=bogus branch new HEAD", i.e. the
221 operation modes of the "git branch" command that do not need the
222 sort key information, no longer errors out by seeing a bogus sort
223 key.
224 (merge 98e7ab6d42 jc/fix-ref-sorting-parse later to maint).
225
226 * The compatibility implementation for unsetenv(3) were written to
227 mimic ancient, non-POSIX, variant seen in an old glibc; it has been
228 changed to return an integer to match the more modern era.
229 (merge a38989bd5b jc/unsetenv-returns-an-int later to maint).
230
231 * The clean/smudge conversion code path has been prepared to better
232 work on platforms where ulong is narrower than size_t.
233 (merge 596b5e77c9 mc/clean-smudge-with-llp64 later to maint).
234
235 * Redact the path part of packfile URI that appears in the trace output.
236 (merge 0ba558ffb1 if/redact-packfile-uri later to maint).
237
238 * CI has been taught to catch some Unicode directional formatting
239 sequence that can be used in certain mischief.
240 (merge 0e7696c64d js/ci-no-directional-formatting later to maint).
241
242 * The "--date=format:<strftime>" gained a workaround for the lack of
243 system support for a non-local timezone to handle "%s" placeholder.
244 (merge 9b591b9403 jk/strbuf-addftime-seconds-since-epoch later to maint).
245
246 * The "merge" subcommand of "git jump" (in contrib/) silently ignored
247 pathspec and other parameters.
248 (merge 67ba13e5a4 jk/jump-merge-with-pathspec later to maint).
249
250 * The code to decode the length of packed object size has been
251 corrected.
252 (merge 34de5b8eac jt/pack-header-lshift-overflow later to maint).
253
254 * The advice message given by "git pull" when the user hasn't made a
255 choice between merge and rebase still said that the merge is the
256 default, which no longer is the case. This has been corrected.
257 (merge 71076d0edd ah/advice-pull-has-no-preference-between-rebase-and-merge later to maint).
258
259 * "git fetch", when received a bad packfile, can fail with SIGPIPE.
260 This wasn't wrong per-se, but we now detect the situation and fail
261 in a more predictable way.
262 (merge 2a4aed42ec jk/fetch-pack-avoid-sigpipe-to-index-pack later to maint).
263
264 * The function to cull a child process and determine the exit status
265 had two separate code paths for normal callers and callers in a
266 signal handler, and the latter did not yield correct value when the
267 child has caught a signal. The handling of the exit status has
268 been unified for these two code paths. An existing test with
269 flakiness has also been corrected.
270 (merge 5263e22cba jk/t7006-sigpipe-tests-fix later to maint).
271
272 * When a non-existent program is given as the pager, we tried to
273 reuse an uninitialized child_process structure and crashed, which
274 has been fixed.
275 (merge f917f57f40 em/missing-pager later to maint).
276
277 * The single-key-input mode in "git add -p" had some code to handle
278 keys that generate a sequence of input via ReadKey(), which did not
279 handle end-of-file correctly, which has been fixed.
280 (merge fc8a8126df cb/add-p-single-key-fix later to maint).
281
282 * "git rebase -x" added an unnecessary 'exec' instructions before
283 'noop', which has been corrected.
284 (merge cc9dcdee61 en/rebase-x-fix later to maint).
285
286 * When the "git push" command is killed while the receiving end is
287 trying to report what happened to the ref update proposals, the
288 latter used to die, due to SIGPIPE. The code now ignores SIGPIPE
289 to increase our chances to run the post-receive hook after it
290 happens.
291 (merge d34182b9e3 rj/receive-pack-avoid-sigpipe-during-status-reporting later to maint).
292
293 * "git worktree add" showed "Preparing worktree" message to the
294 standard output stream, but when it failed, the message from die()
295 went to the standard error stream. Depending on the order the
296 stdio streams are flushed at the program end, this resulted in
297 confusing output. It has been corrected by sending all the chatty
298 messages to the standard error stream.
299 (merge b50252484f es/worktree-chatty-to-stderr later to maint).
300
301 * Coding guideline document has been updated to clarify what goes to
302 standard error in our system.
303 (merge e258eb4800 es/doc-stdout-vs-stderr later to maint).
304
305 * The sparse-index/sparse-checkout feature had a bug in its use of
306 the matching code to determine which path is in or outside the
307 sparse checkout patterns.
308 (merge 8c5de0d265 ds/sparse-deep-pattern-checkout-fix later to maint).
309
310 * "git rebase -x" by mistake started exporting the GIT_DIR and
311 GIT_WORK_TREE environment variables when the command was rewritten
312 in C, which has been corrected.
313 (merge 434e0636db en/rebase-x-wo-git-dir-env later to maint).
314
315 * When "git log" implicitly enabled the "decoration" processing
316 without being explicitly asked with "--decorate" option, it failed
317 to read and honor the settings given by the "--decorate-refs"
318 option.
319
320 * "git fetch --set-upstream" did not check if there is a current
321 branch, leading to a segfault when it is run on a detached HEAD,
322 which has been corrected.
323 (merge 17baeaf82d ab/fetch-set-upstream-while-detached later to maint).
324
325 * Among some code paths that ask an yes/no question, only one place
326 gave a prompt that looked different from the others, which has been
327 updated to match what the others create.
328 (merge 0fc8ed154c km/help-prompt-fix later to maint).
329
330 * "git log --invert-grep --author=<name>" used to exclude commits
331 written by the given author, but now "--invert-grep" only affects
332 the matches made by the "--grep=<pattern>" option.
333 (merge 794c000267 rs/log-invert-grep-with-headers later to maint).
334
335 * "git grep --perl-regexp" failed to match UTF-8 characters with
336 wildcard when the pattern consists only of ASCII letters, which has
337 been corrected.
338 (merge 32e3e8bc55 rs/pcre2-utf later to maint).
339
340 * Certain sparse-checkout patterns that are valid in non-cone mode
341 led to segfault in cone mode, which has been corrected.
342
343 * Use of certain "git rev-list" options with "git fast-export"
344 created nonsense results (the worst two of which being "--reverse"
345 and "--invert-grep --grep=<foo>"). The use of "--first-parent" is
346 made to behave a bit more sensible than before.
347 (merge 726a228dfb ws/fast-export-with-revision-options later to maint).
348
349 * Perf tests were run with end-user's shell, but it has been
350 corrected to use the shell specified by $TEST_SHELL_PATH.
351 (merge 9ccab75608 ja/perf-use-specified-shell later to maint).
352
353 * Fix dependency rules to generate hook-list.h header file.
354 (merge d3fd1a6667 ab/makefile-hook-list-dependency-fix later to maint).
355
356 * "git stash" by default triggers its "push" action, but its
357 implementation also made "git stash -h" to show short help only for
358 "git stash push", which has been corrected.
359 (merge ca7990cea5 ab/do-not-limit-stash-help-to-push later to maint).
360
361 * "git apply --3way" bypasses the attempt to do a three-way
362 application in more cases to address the regression caused by the
363 recent change to use direct application as a fallback.
364 (merge 34d607032c jz/apply-3-corner-cases later to maint).
365
366 * Fix performance-releated bug in "git subtree" (in contrib/).
367 (merge 3ce8888fb4 jl/subtree-check-parents-argument-passing-fix later to maint).
368
369 * Extend the guidance to choose the base commit to build your work
370 on, and hint/nudge contributors to read others' changes.
371 (merge fdfae830f8 jc/doc-submitting-patches-choice-of-base later to maint).
372
373 * A corner case bug in the ort merge strategy has been corrected.
374 (merge d30126c20d en/merge-ort-renorm-with-rename-delete-conflict-fix later to maint).
375
376 * "git stash apply" forgot to attempt restoring untracked files when
377 it failed to restore changes to tracked ones.
378 (merge 71cade5a0b en/stash-df-fix later to maint).
379
380 * Calling dynamically loaded functions on Windows has been corrected.
381 (merge 4a9b204920 ma/windows-dynload-fix later to maint).
382
383 * Some lockfile code called free() in signal-death code path, which
384 has been corrected.
385 (merge 58d4d7f1c5 ps/lockfile-cleanup-fix later to maint).
386
387 * Other code cleanup, docfix, build fix, etc.
388 (merge 74db416c9c cw/protocol-v2-doc-fix later to maint).
389 (merge f9b2b6684d ja/doc-cleanup later to maint).
