1 | Git 2.30 Release Notes |
2 | ====================== | |
3 | ||
4 | Updates since v2.29 | |
5 | ------------------- | |
6 | ||
7 | UI, Workflows & Features | |
8 | ||
f9b6481a JH |
9 | * Userdiff for PHP update. |
10 | ||
11 | * Userdiff for Rust update. | |
12 | ||
13 | * Userdiff for CSS update. | |
14 | ||
15 | * The command line completion script (in contrib/) learned that "git | |
16 | stash show" takes the options "git diff" takes. | |
17 | ||
18 | * "git worktree list" now shows if each worktree is locked. This | |
19 | possibly may open us to show other kinds of states in the future. | |
20 | ||
21 | * "git maintenance", an extended big brother of "git gc", continues | |
22 | to evolve. | |
23 | ||
24 | * "git push --force-with-lease[=<ref>]" can easily be misused to lose | |
25 | commits unless the user takes good care of their own "git fetch". | |
26 | A new option "--force-if-includes" attempts to ensure that what is | |
27 | being force-pushed was created after examining the commit at the | |
28 | tip of the remote ref that is about to be force-replaced. | |
29 | ||
30 | * "git clone" learned clone.defaultremotename configuration variable | |
31 | to customize what nickname to use to call the remote the repository | |
32 | was cloned from. | |
33 | ||
34 | * "git checkout" learned to use checkout.guess configuration variable | |
35 | and enable/disable its "--[no-]guess" option accordingly. | |
36 | ||
e2850a27 JH |
37 | * "git resurrect" script (in contrib/) learned that the object names |
38 | may be longer than 40-hex depending on the hash function in use. | |
39 | ||
7f7ebe05 JH |
40 | * "git diff A...B" learned "git diff --merge-base A B", which is a |
41 | longer short-hand to say the same thing. | |
42 | ||
43 | * A sample 'push-to-checkout' hook, that performs the same as | |
44 | what the built-in default action does, has been added. | |
45 | ||
46 | * "git diff" family of commands learned the "-I<regex>" option to | |
47 | ignore hunks whose changed lines all match the given pattern. | |
48 | ||
49 | * The userdiff pattern learned to identify the function definition in | |
50 | POSIX shells and bash. | |
51 | ||
e4d83eee JH |
52 | * "git checkout-index" did not consistently signal an error with its |
53 | exit status, but now it does. | |
54 | ||
55 | * A commit and tag object may have CR at the end of each and | |
56 | every line (you can create such an object with hash-object or | |
57 | using --cleanup=verbatim to decline the default clean-up | |
58 | action), but it would make it impossible to have a blank line | |
59 | to separate the title from the body of the message. We are now | |
60 | more lenient and accept a line with lone CR on it as a blank line, | |
61 | too. | |
62 | ||
63 | * Exit codes from "git remote add" etc. were not usable by scripted | |
64 | callers, but now they are. | |
65 | ||
faefdd61 JH |
66 | * "git archive" now allows compression level higher than "-9" |
67 | when generating tar.gz output. | |
68 | ||
e4d83eee JH |
69 | * Zsh autocompletion (in contrib/) update. |
70 | ||
1d1c4a87 JH |
71 | |
72 | Performance, Internal Implementation, Development Support etc. | |
73 | ||
f9b6481a JH |
74 | * Use "git archive" more to produce the release tarball. |
75 | ||
e2850a27 JH |
76 | * GitHub Actions automated test improvement to skip tests on a tree |
77 | identical to what has already been tested. | |
f9b6481a | 78 | |
7f7ebe05 JH |
79 | * Test-coverage for running commit-graph task "git maintenance" has |
80 | been extended. | |
81 | ||
82 | * Our test scripts can be told to run only individual pieces while | |
83 | skipping others with the "--run=..." option; they were taught to | |
84 | take a substring of test title, in addition to numbers, to name the | |
85 | test pieces to run. | |
86 | ||
87 | * Adjust tests so that they won't scream when the default initial | |
88 | branch name is changed to 'main'. | |
89 | ||
e4d83eee JH |
90 | * Rewriting "git bisect" in C continues. |
91 | ||
92 | * More preliminary tests have been added to document desired outcome | |
93 | of various "directory rename" situations. | |
94 | ||
95 | * Micro clean-up of a couple of test scripts. | |
96 | ||
97 | * "git diff" and other commands that share the same machinery to | |
98 | compare with working tree files have been taught to take advantage | |
99 | of the fsmonitor data when available. | |
100 | ||
101 | * The code to detect premature EOF in the sideband demultiplexer has | |
102 | been cleaned up. | |
103 | ||
104 | * Test scripts are being prepared to transition of the default branch | |
105 | name to 'main'. | |
106 | ||
faefdd61 JH |
107 | * "git fetch --depth=<n>" over the stateless RPC / smart HTTP |
108 | transport handled EOF from the client poorly at the server end. | |

110 | |
111 | Fixes since v2.29 | |
112 | ----------------- | |
113 | ||
114 | * In 2.29, "--committer-date-is-author-date" option of "rebase" and | |
115 | "am" subcommands lost the e-mail address by mistake, which has been | |
116 | corrected. | |
117 | (merge 5f35edd9d7 jk/committer-date-is-author-date-fix later to maint). | |
118 | ||
f9b6481a JH |
119 | * "git checkout -p A...B [-- <path>]" did not work, even though the |
120 | same command without "-p" correctly used the merge-base between | |
121 | commits A and B. | |
122 | (merge 35166b1fb5 dl/checkout-p-merge-base later to maint). | |
123 | ||
7f7ebe05 JH |
124 | * The side-band status report can be sent at the same time as the |
125 | primary payload multiplexed, but the demultiplexer on the receiving | |
126 | end incorrectly split a single status report into two, which has | |
127 | been corrected. | |
128 | (merge 712b0377db js/avoid-split-sideband-message later to maint). | |
129 | ||
130 | * "git fast-import" wasted a lot of memory when many marks were in use. | |
131 | (merge 3f018ec716 jk/fast-import-marks-alloc-fix later to maint). | |
132 | ||
133 | * A test helper "test_cmp A B" was taught to diagnose missing files A | |
134 | or B as a bug in test, but some tests legitimately wanted to notice | |
135 | a failure to even create file B as an error, in addition to leaving | |
136 | the expected result in it, and were misdiagnosed as a bug. This | |
137 | has been corrected. | |
138 | (merge 262d5ad5a5 es/test-cmp-typocatcher later to maint). | |
139 | ||
140 | * When "git commit-graph" detects the same commit recorded more than | |
141 | once while it is merging the layers, it used to die. The code now | |
142 | ignores all but one of them and continues. | |
143 | (merge 85102ac71b ds/commit-graph-merging-fix later to maint). | |
144 | ||
145 | * The meaning of a Signed-off-by trailer can vary from project to | |
146 | project; this and also what it means to this project has been | |
147 | clarified in the documentation. | |
148 | (merge 3abd4a67d9 bk/sob-dco later to maint). | |
149 | ||
150 | * "git credential' didn't honor the core.askPass configuration | |
151 | variable (among other things), which has been corrected. | |
152 | (merge 567ad2c0f9 tk/credential-config later to maint). | |
153 | ||
154 | * Dev support to catch a tentative definition of a variable in our C | |
155 | code as an error. | |
156 | (merge 5539183622 jk/no-common later to maint). | |
157 | ||
158 | * "git rebase --rebase-merges" did not correctly pass --gpg-sign | |
159 | command line option to underlying "git merge" when replaying a merge | |
160 | using non-default merge strategy or when replaying an octopus merge | |
161 | (because replaying a two-head merge with the default strategy was | |
162 | done in a separate codepath, the problem did not trigger for most | |
163 | users), which has been corrected. | |
164 | (merge 43ad4f2eca sc/sequencer-gpg-octopus later to maint). | |
165 | ||
166 | * "git apply -R" did not handle patches that touch the same path | |
167 | twice correctly, which has been corrected. This is most relevant | |
168 | in a patch that changes a path from a regular file to a symbolic | |
169 | link (and vice versa). | |
170 | (merge b0f266de11 jt/apply-reverse-twice later to maint). | |
171 | ||
172 | * A recent oid->hash conversion missed one spot, breaking "git svn". | |
173 | (merge 03bb366de4 bc/svn-hash-oid-fix later to maint). | |
174 | ||
e31aba42 JH |
175 | * The documentation on the "--abbrev=<n>" option did not say the |
176 | output may be longer than "<n>" hexdigits, which has been | |
177 | clarified. | |
178 | (merge cda34e0d0c jc/abbrev-doc later to maint). | |
179 | ||
180 | * "git p4" now honors init.defaultBranch configuration. | |
181 | (merge 1b09d1917f js/p4-default-branch later to maint). | |
182 | ||
183 | * Recently the format of an internal state file "rebase -i" uses has | |
184 | been tightened up for consistency, which would hurt those who start | |
185 | "rebase -i" with old git and then continue with new git. Loosen | |
186 | the reader side a bit (which we may want to tighten again in a year | |
187 | or so). | |
188 | (merge c779386182 jc/sequencer-stopped-sha-simplify later to maint). | |
189 | ||
faefdd61 JH |
190 | * The code to see if "git stash drop" can safely remove refs/stash |
191 | has been made more carerful. | |
192 | (merge 4f44c5659b rs/empty-reflog-check-fix later to maint). | |
193 | ||
194 | * "git log -L<range>:<path>" is documented to take no pathspec, but | |
195 | this was not enforced by the command line option parser, which has | |
196 | been corrected. | |
197 | (merge 39664cb0ac jc/line-log-takes-no-pathspec later to maint). | |
198 | ||
199 | * "git format-patch --output=there" did not work as expected and | |
200 | instead crashed. The option is now supported. | |
201 | (merge dc1672dd10 jk/format-patch-output later to maint). | |
202 | ||
203 | * Define ARM64 compiled with MSVC to be little-endian. | |
204 | (merge 0c038fc65a dg/bswap-msvc later to maint). | |
205 | ||
206 | * "git rebase -i" did not store ORIG_HEAD correctly. | |
207 | (merge 8843302307 pw/rebase-i-orig-head later to maint). | |
208 | ||
209 | * "git blame -L :funcname -- path" did not work well for a path for | |
210 | which a userdiff driver is defined. | |
211 | ||
212 | * "make DEVELOPER=1 sparse" used to run sparse and let it emit | |
213 | warnings; now such warnings will cause an error. | |
214 | (merge 521dc56270 jc/sparse-error-for-developer-build later to maint). | |
215 | ||
216 | * "git blame --ignore-revs-file=<file>" learned to ignore a | |
217 | non-existent object name in the input, instead of complaining. | |
218 | (merge c714d05875 jc/blame-ignore-fix later to maint). | |
219 | ||
1d1c4a87 JH |
220 | * Other code cleanup, docfix, build fix, etc. |
221 | (merge 3e0a5dc9af cc/doc-filter-branch-typofix later to maint). | |
f9b6481a JH |
222 | (merge 32c83afc2c cw/ci-ghwf-check-ws-errors later to maint). |

7f7ebe05 JH |
224 | (merge 6db29ab213 jk/fast-import-marks-cleanup later to maint). |
225 | (merge e5cf6d3df4 nk/dir-c-comment-update later to maint). | |
226 | (merge 5710dcce74 jk/report-fn-typedef later to maint). | |
227 | (merge 9a82db1056 en/sequencer-rollback-lock-cleanup later to maint). | |
228 | (merge 4e1bee9a99 js/t7006-cleanup later to maint). | |
229 | (merge f5bcde6c58 es/tutorial-mention-asciidoc-early later to maint). | |
