1 GIT v1.5.4 Release Notes
2 ========================
3
4 Removal
5 -------
6
7 * "git svnimport" was removed in favor of "git svn". It is still there
8 in the source tree (contrib/examples) but unsupported.
9
10 * As git-commit and git-status have been rewritten, "git runstatus"
11 helper script lost all its users and has been removed.
12
13
14 Temporarily disabled
15 --------------------
16
17 * "git http-push" is known not to work well with cURL library older
18 than 7.16, and we had reports of repository corruption. It is
19 disabled on such platforms for now. Unfortunately, 1.5.3.8 shares
20 the same issue. In other words, this does not mean you will be
21 fine if you stick to an older git release. For now, please do not
22 use http-push from older git with cURL older than 7.16 if you
23 value your data. A proper fix will hopefully materialize in
24 later versions.
25
26
27 Deprecation notices
28 -------------------
29
30 * From v1.6.0, git will by default install dashed form of commands
31 (e.g. "git-commit") outside of users' normal $PATH, and will install
32 only selected commands ("git" itself, and "gitk") in $PATH. This
33 implies:
34
35 - Using dashed forms of git commands (e.g. "git-commit") from the
36 command line has been informally deprecated since early 2006, but
37 now it officially is, and will be removed in the future. Use
38 dash-less forms (e.g. "git commit") instead.
39
40 - Using dashed forms from your scripts, without first prepending the
41 return value from "git --exec-path" to the scripts' PATH, has been
42 informally deprecated since early 2006, but now it officially is.
43
44 - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
45 PATH" early in your script is not deprecated with this change.
46
47 Users are strongly encouraged to adjust their habits and scripts now
48 to prepare for this change.
49
50 * The post-receive hook was introduced in March 2007 to supersede
51 the post-update hook, primarily to overcome the command line length
52 limitation of the latter. Use of post-update hook will be deprecated
53 in future versions of git, starting from v1.6.0.
54
55 * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
56 option, and will be removed in the future.
57
58 * "git peek-remote" is deprecated, as "git ls-remote" was written in C
59 and works for all transports; "git peek-remote" will be removed in
60 the future.
61
62 * "git repo-config" which was an old name for "git config" command
63 has been supported without being advertised for a long time. The
64 next feature release will remove it.
65
66 * From v1.6.0, the repack.usedeltabaseoffset config option will default
67 to true, which will give denser packfiles (i.e. more efficient storage).
68 The downside is that git older than version 1.4.4 will not be able
69 to directly use a repository packed using this setting.
70
71 * From v1.6.0, the pack.indexversion config option will default to 2,
72 which is slightly more efficient, and makes repacking more immune to
73 data corruptions. Git older than version 1.5.2 may revert to version 1
74 of the pack index with a manual "git index-pack" to be able to directly
75 access corresponding pack files.
76
77
78 Updates since v1.5.3
79 --------------------
80
81 * Comes with much improved gitk, with i18n.
82
83 * Comes with git-gui 0.9.2 with i18n.
84
85 * gitk is now merged as a subdirectory of git.git project, in
86 preparation for its i18n.
87
88 * progress displays from many commands are a lot nicer to the eye.
89 Transfer commands show throughput data.
90
91 * many commands that pay attention to per-directory .gitignore now do
92 so lazily, which makes the usual case go much faster.
93
94 * Output processing for '--pretty=format:<user format>' has been
95 optimized.
96
97 * Rename detection of diff family while detecting exact matches has
98 been greatly optimized.
99
100 * Rename detection of diff family tries to make more natural looking
101 pairing. Earlier, if multiple identical rename sources were
102 found in the preimage, the source used was picked pretty much at random.
103
104 * Value "true" for color.diff and color.status configuration used to
105 mean "always" (even when the output is not going to a terminal).
106 This has been corrected to mean the same thing as "auto".
107
108 * "git diff" Porcelain now respects diff.external configuration, which
109 is another way to specify GIT_EXTERNAL_DIFF.
110
111 * "git diff" can be told to use different prefixes other than
112 "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
113
114 * "git diff" sometimes did not quote paths with funny
115 characters properly.
116
117 * "git log" (and any revision traversal commands) misbehaved
118 when --diff-filter is given but was not asked to actually
119 produce diff.
120
121 * HTTP proxy can be specified per remote repository using
122 remote.*.httpproxy configuration, or global http.proxy configuration
123 variable.
124
125 * Various Perforce importer updates.
126
127 * Example update and post-receive hooks have been improved.
128
129 * Any command that wants to take a commit object name can now use
130 ":/string" syntax to name a commit.
131
132 * "git reset" is now built-in and its output can be squelched with -q.
133
134 * "git reset --hard" does not make any sense in a bare
135 repository, but did not error out; fixed.
136
137 * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
138
139 * "git rebase" learned --whitespace option.
140
141 * In "git rebase", when you decide not to replay a particular change
142 after the command stopped with a conflict, you can say "git rebase
143 --skip" without first running "git reset --hard", as the command now
144 runs it for you.
145
146 * "git rebase --interactive" mode can now work on detached HEAD.
147
148 * Other minor to serious bugs in "git rebase -i" have been fixed.
149
150 * "git rebase" now detaches head during its operation, so after a
151 successful "git rebase" operation, the reflog entry branch@{1} for
152 the current branch points at the commit before the rebase was
153 started.
154
155 * "git rebase -i" also triggers rerere to help your repeated merges.
156
157 * "git merge" can call the "post-merge" hook.
158
159 * "git pack-objects" can optionally run deltification with multiple
160 threads.
161
162 * "git archive" can optionally substitute keywords in files marked with
163 export-subst attribute.
164
165 * "git cherry-pick" made a misguided attempt to repeat the original
166 command line in the generated log message, when told to cherry-pick a
167 commit by naming a tag that points at it. It does not anymore.
168
169 * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the
170 various date fields in different formats.
171
172 * "git gc --auto" is a low-impact way to automatically run a variant of
173 "git repack" that does not lose unreferenced objects (read: safer
174 than the usual one) after the user accumulates too many loose
175 objects.
176
177 * "git clean" has been rewritten in C.
178
179 * You need to explicitly set clean.requireForce to "false" to allow
180 "git clean" without -f to do any damage (lack of the configuration
181 variable used to mean "do not require -f option to lose untracked
182 files", but we now use the safer default).
183
184 * The kinds of whitespace errors "git diff" and "git apply" notice (and
185 fix) can be controlled via 'core.whitespace' configuration variable
186 and 'whitespace' attribute in .gitattributes file.
187
188 * "git push" learned --dry-run option to show what would happen if a
189 push is run.
190
191 * "git push" does not update a tracking ref on the local side when the
192 remote refused to update the corresponding ref.
193
194 * "git push" learned --mirror option. This is to push the local refs
195 one-to-one to the remote, and deletes refs from the remote that do
196 not exist anymore in the repository on the pushing side.
197
198 * "git push" can remove a corrupt ref at the remote site with the usual
199 ":ref" refspec.
200
201 * "git remote" knows --mirror mode. This is to set up configuration to
202 push into a remote repository to store local branch heads to the same
203 branch on the remote side, and remove branch heads locally removed
204 from local repository at the same time. Suitable for pushing into a
205 back-up repository.
206
207 * "git remote" learned "rm" subcommand.
208
209 * "git cvsserver" can be run via "git shell". Also, "cvs" is
210 recognized as a synonym for "git cvsserver", so that CVS users
211 can be switched to git just by changing their login shell.
212
213 * "git cvsserver" acts more like receive-pack by running post-receive
214 and post-update hooks.
215
216 * "git am" and "git rebase" are far less verbose.
217
218 * "git pull" learned to pass --[no-]ff option to underlying "git
219 merge".
220
221 * "git pull --rebase" is a different way to integrate what you fetched
222 into your current branch.
223
224 * "git fast-export" produces data-stream that can be fed to fast-import
225 to reproduce the history recorded in a git repository.
226
227 * "git add -i" takes pathspecs to limit the set of files to work on.
228
229 * "git add -p" is a short-hand to go directly to the selective patch
230 subcommand in the interactive command loop and to exit when done.
231
232 * "git add -i" UI has been colorized. The interactive prompt
233 and menu can be colored by setting color.interactive
234 configuration. The diff output (including the hunk picker)
235 are colored with color.diff configuration.
236
237 * "git commit --allow-empty" allows you to create a single-parent
238 commit that records the same tree as its parent, overriding the usual
239 safety valve.
240
241 * "git commit --amend" can amend a merge that does not change the tree
242 from its first parent.
243
244 * "git commit" used to unconditionally strip comment lines that
245 began with '#' and removed excess blank lines. This behavior has
246 been made configurable.
247
248 * "git commit" has been rewritten in C.
249
250 * "git stash random-text" does not create a new stash anymore. It was
251 a UI mistake. Use "git stash save random-text", or "git stash"
252 (without extra args) for that.
253
254 * "git stash clear extra-text" does not clear the whole stash
255 anymore. It is tempting to expect "git stash clear stash@{2}"
256 to drop only a single named stash entry, and it is rude to
257 discard everything when that is asked (but not provided).
258
259 * "git prune --expire <time>" can exempt young loose objects from
260 getting pruned.
261
262 * "git branch --contains <commit>" can list branches that are
263 descendants of a given commit.
264
265 * "git log" learned --early-output option to help interactive GUI
266 implementations.
267
268 * "git bisect" learned "skip" action to mark untestable commits.
269
270 * "git bisect visualize" learned a shorter synonym "git bisect view".
271
272 * "git bisect visualize" runs "git log" in a non-windowed
273 environments. It also can be told what command to run (e.g. "git
274 bisect visualize tig").
275
276 * "git format-patch" learned "format.numbered" configuration variable
277 to automatically turn --numbered option on when more than one commits
278 are formatted.
279
280 * "git ls-files" learned "--exclude-standard" to use the canned set of
281 exclude files.
282
283 * "git tag -a -f existing" begins the editor session using the existing
284 annotation message.
285
286 * "git tag -m one -m bar" (multiple -m options) behaves similarly to
287 "git commit"; the parameters to -m options are formatted as separate
288 paragraphs.
289
290 * The format "git show" outputs an annotated tag has been updated to
291 include "Tagger: " and "Date: " lines from the tag itself. Strictly
292 speaking this is a backward incompatible change, but this is a
293 reasonable usability fix and people's scripts shouldn't have been
294 relying on the exact output from "git show" Porcelain anyway.
295
296 * "git cvsimport" did not notice errors from underlying "cvsps"
297 and produced a corrupt import silently.
298
299 * "git cvsexportcommit" learned -w option to specify and switch to the
300 CVS working directory.
301
302 * "git checkout" from a subdirectory learned to use "../path" to allow
303 checking out a path outside the current directory without cd'ing up.
304
305 * "git checkout" from and to detached HEAD leaves a bit more
306 information in the reflog.
307
308 * "git send-email --dry-run" shows full headers for easier diagnosis.
309
310 * "git merge-ours" is now built-in.
311
312 * "git svn" learned "info" and "show-externals" subcommands.
313
314 * "git svn" run from a subdirectory failed to read settings from the
315 .git/config.
316
317 * "git svn" learned --use-log-author option, which picks up more
318 descriptive name from From: and Signed-off-by: lines in the commit
319 message.
320
321 * "git svn" wasted way too much disk to record revision mappings
322 between svn and git; a new representation that is much more compact
323 for this information has been introduced to correct this.
324
325 * "git svn" left temporary index files it used without cleaning them
326 up; this was corrected.
327
328 * "git status" from a subdirectory now shows relative paths, which
329 makes copy-and-pasting for git-checkout/git-add/git-rm easier. The
330 traditional behavior to show the full path relative to the top of
331 the work tree can be had by setting status.relativepaths
332 configuration variable to false.
333
334 * "git blame" kept text for each annotated revision in core needlessly;
335 this has been corrected.
336
337 * "git shortlog" learned to default to HEAD when the standard input is
338 a terminal and the user did not give any revision parameter.
339
340 * "git shortlog" learned "-e" option to show e-mail addresses as well as
341 authors' names.
342
343 * "git help" learned "-w" option to show documentation in browsers.
344
345 * In addition there are quite a few internal clean-ups. Notably:
346
347 - many fork/exec have been replaced with run-command API,
348 brought from the msysgit effort.
349
350 - introduction and more use of the option parser API.
351
352 - enhancement and more use of the strbuf API.
353
354 * Makefile tweaks to support HP-UX is in.
355
356 Fixes since v1.5.3
357 ------------------
358
359 All of the fixes in v1.5.3 maintenance series are included in
360 this release, unless otherwise noted.
361
362 These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
363 series.
364
365 * The way "git diff --check" behaves is much more consistent with the way
366 "git apply --whitespace=warn" works.
367
368 * "git svn" talking with the SVN over HTTP will correctly quote branch
369 and project names.
370
371 * "git config" did not work correctly on platforms that define
372 REG_NOMATCH to an even number.
373
374 * Recent versions of AsciiDoc 8 has a change to break our
375 documentation; a workaround has been implemented.
376
377 * "git diff --color-words" colored context lines in a wrong color.
