1 GIT v1.5.1 Release Notes
2 ========================
7 * Deprecated commands and options.
9 - git-diff-stages and git-resolve have been removed.
11 * New commands and options.
13 - "git log" and friends take --reverse, which instructs them
14 to give their output in the order opposite from their usual.
15 They typically output from new to old, but with this option
16 their output would read from old to new. "git shortlog"
17 usually lists older commits first, but with this option,
18 they are shown from new to old.
20 - "git log --pretty=format:<string>" to allow more flexible
23 - "git diff" learned --ignore-space-at-eol. This is a weaker
24 form of --ignore-space-change.
26 - "git diff --no-index pathA pathB" can be used as diff
27 replacement with git specific enhancements.
29 - "git diff --no-index" can read from '-' (standard input).
31 - "git diff" also learned --exit-code to exit with non-zero
32 status when it found differences. In the future we might
33 want to make this the default but that would be a rather big
34 backward incompatible change; it will stay as an option for
37 - "git diff --quiet" is --exit-code with output turned off,
38 meant for scripted use to quickly determine if there is any
39 tree-level difference.
41 - Textual patch generation with "git diff" without -w/-b
42 option has been significantly optimized. "git blame" got
43 faster because of the same change.
45 - "git log" and "git rev-list" has been optimized
46 significantly when they are used with pathspecs.
48 - "git branch --track" can be used to set up configuration
49 variables to help it easier to base your work on branches
50 you track from a remote site.
52 - "git format-patch --attach" now emits attachments. Use
53 --inline to get an inlined multipart/mixed.
55 - "git name-rev" learned --refs=<pattern>, to limit the tags
56 used for naming the given revisions only to the ones
57 matching the given pattern.
59 - "git remote update" is to run "git fetch" for defined remotes
60 to update tracking branches.
62 - "git cvsimport" can now take '-d' to talk with a CVS
63 repository different from what are recorded in CVS/Root
64 (overriding it with environment CVSROOT does not work).
66 - "git bundle" can help sneaker-netting your changes between
69 - "git mergetool" can help 3-way file-level conflict
70 resolution with your favorite graphical merge tools.
72 - A new configuration "core.symlinks" can be used to disable
73 symlinks on filesystems that do not support them; they are
74 checked out as regular files instead.
76 - You can name a commit object with its first line of the
77 message. The syntax to use is ':/message text'. E.g.
79 $ git show ":/object name: introduce ':/<oneline prefix>' notation"
81 means the same thing as:
83 $ git show 28a4d940443806412effa246ecc7768a21553ec7
85 - "git bisect" learned a new command "run" that takes a script
86 to run after each revision is checked out to determine if it
87 is good or bad, to automate the bisection process.
89 - "git log" family learned a new traversal option --first-parent,
90 which does what the name suggests.
93 * Updated behavior of existing commands.
95 - "git-merge-recursive" used to barf when there are more than
96 one common ancestors for the merge, and merging them had a
97 rename/rename conflict. This has been fixed.
99 - "git fsck" does not barf on corrupt loose objects.
101 - "git rm" does not remove newly added files without -f.
103 - "git archimport" allows remapping when coming up with git
104 branch names from arch names.
106 - git-svn got almost a rewrite.
108 - core.autocrlf configuration, when set to 'true', makes git
109 to convert CRLF at the end of lines in text files to LF when
110 reading from the filesystem, and convert in reverse when
111 writing to the filesystem. The variable can be set to
112 'input', in which case the conversion happens only while
113 reading from the filesystem but files are written out with
114 LF at the end of lines. Currently, which paths to consider
115 'text' (i.e. be subjected to the autocrlf mechanism) is
116 decided purely based on the contents, but the plan is to
117 allow users to explicitly override this heuristic based on
120 - The behavior of 'git-apply', when run in a subdirectory,
121 without --index nor --cached were inconsistent with that of
122 the command with these options. This was fixed to match the
123 behavior with --index. A patch that is meant to be applied
124 with -p1 from the toplevel of the project tree can be
125 applied with any custom -p<n> option. A patch that is not
126 relative to the toplevel needs to be applied with -p<n>
127 option with or without --index (or --cached).
129 - "git diff" outputs a trailing HT when pathnames have embedded
130 SP on +++/--- header lines, in order to help "GNU patch" to
131 parse its output. "git apply" was already updated to accept
132 this modified output format since ce74618d (Sep 22, 2006).
134 - "git cvsserver" runs hooks/update and honors its exit status.
136 - "git cvsserver" can be told to send everything with -kb.
138 - "git diff --check" also honors the --color output option.
140 - "git name-rev" used to stress the fact that a ref is a tag too
141 much, by saying something like "v1.2.3^0~22". It now says
142 "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
143 not talk about an ancestor of the commit that is tagged, which
146 - "git rev-list --boundary" now shows boundary markers for the
147 commits omitted by --max-age and --max-count condition.
149 - The configuration mechanism now reads $(prefix)/etc/gitconfig.
151 - "git apply --verbose" shows what preimage lines were wanted
152 when it couldn't find them.
154 - "git status" in a read-only repository got a bit saner.
156 - "git fetch" (hence "git clone" and "git pull") are less
157 noisy when the output does not go to tty.
159 - "git fetch" between repositories with many refs were slow
160 even when there are not many changes that needed
161 transferring. This has been sped up by partially rewriting
162 the heaviest parts in C.
164 - "git mailinfo" which splits an e-mail into a patch and the
165 meta-information was rewritten, thanks to Don Zickus. It
166 handles nested multipart better. The command was broken for
167 a brief period on 'master' branch since 1.5.0 but the
168 breakage is fixed now.
170 - send-email learned configurable bcc and chain-reply-to.
172 - "git remote show $remote" also talks about branches that
173 would be pushed if you run "git push remote".
175 - Using objects from packs is now seriously optimized by clever
176 use of a cache. This should be most noticeable in git-log
177 family of commands that involve reading many tree objects.
178 In addition, traversing revisions while filtering changes
179 with pathspecs is made faster by terminating the comparison
180 between the trees as early as possible.
185 - The part to send out notification e-mails was removed from
186 the sample update hook, as it was not an appropriate place
187 to do so. The proper place to do this is the new post-receive
188 hook. An example hook has been added to contrib/hooks/.
193 - git-revert, git-gc and git-cherry-pick are now built-ins.
198 These are all in v1.5.0.x series.
200 * Documentation updates
202 - Clarifications and corrections to 1.5.0 release notes.
204 - The main documentation did not link to git-remote documentation.
206 - Clarified introductory text of git-rebase documentation.
208 - Converted remaining mentions of update-index on Porcelain
209 documents to git-add/git-rm.
211 - Some i18n.* configuration variables were incorrectly
212 described as core.*; fixed.
214 - added and clarified core.bare, core.legacyheaders configurations.
216 - updated "git-clone --depth" documentation.
218 - user-manual updates.
220 - Options to 'git remote add' were described insufficiently.
222 - Configuration format.suffix was not documented.
224 - Other formatting and spelling fixes.
226 - user-manual has better cross references.
228 - gitweb installation/deployment procedure is now documented.
233 - git-upload-pack closes unused pipe ends; earlier this caused
234 many zombies to hang around.
236 - git-rerere was recording the contents of earlier hunks
237 duplicated in later hunks. This prevented resolving the same
238 conflict when performing the same merge the other way around.
240 - git-add and git-update-index on a filesystem on which
241 executable bits are unreliable incorrectly reused st_mode
242 bits even when the path changed between symlink and regular
245 - git-daemon marks the listening sockets with FD_CLOEXEC so
246 that it won't be leaked into the children.
248 - segfault from git-blame when the mandatory pathname
249 parameter was missing was fixed; usage() message is given
252 - git-rev-list did not read $GIT_DIR/config file, which means
253 that did not honor i18n.logoutputencoding correctly.
255 - Automated merge conflict handling when changes to symbolic
256 links conflicted were completely broken. The merge-resolve
257 strategy created a regular file with conflict markers in it
258 in place of the symbolic link. The default strategy,
259 merge-recursive was even more broken. It removed the path
260 that was pointed at by the symbolic link. Both of these
261 problems have been fixed.
263 - 'git diff maint master next' did not correctly give combined
264 diff across three trees.
266 - 'git fast-import' portability fix for Solaris.
268 - 'git show-ref --verify' without arguments did not error out
271 - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
272 slashes after a/ and b/.
274 - 'git format-patch' produced too long filenames if the commit
275 message had too long line at the beginning.
277 - Running 'make all' and then without changing anything
278 running 'make install' still rebuilt some files. This
279 was inconvenient when building as yourself and then
280 installing as root (especially problematic when the source
281 directory is on NFS and root is mapped to nobody).
283 - 'git-rerere' failed to deal with two unconflicted paths that
284 sorted next to each other.
286 - 'git-rerere' attempted to open(2) a symlink and failed if
287 there was a conflict. Since a conflicting change to a
288 symlink would not benefit from rerere anyway, the command
289 now ignores conflicting changes to symlinks.
291 - 'git-repack' did not like to pass more than 64 arguments
292 internally to underlying 'rev-list' logic, which made it
293 impossible to repack after accumulating many (small) packs
296 - 'git-diff' to review the combined diff during a conflicted
297 merge were not reading the working tree version correctly
298 when changes to a symbolic link conflicted. It should have
299 read the data using readlink(2) but read from the regular
300 file the symbolic link pointed at.
302 - 'git-remote' did not like period in a remote's name.
304 - 'git.el' honors the commit coding system from the configuration.
306 - 'blameview' in contrib/ correctly digs deeper when a line is
309 - 'http-push' correctly makes sure the remote side has leading
310 path. Earlier it started in the middle of the path, and
313 - 'git-merge' did not exit with non-zero status when the
314 working tree was dirty and cannot fast forward. It does
317 - 'cvsexportcommit' does not lose yet-to-be-used message file.
319 - int-vs-size_t typefix when running combined diff on files
322 - 'git apply --whitespace=strip' should not touch unmodified
325 - 'git-mailinfo' choke when a logical header line was too long.
327 - 'git show A..B' did not error out. Negative ref ("not A" in
328 this example) does not make sense for the purpose of the
329 command, so now it errors out.
331 - 'git fmt-merge-msg --file' without file parameter did not
334 - 'git archimport' barfed upon encountering a commit without
337 - 'git index-pack' did not protect itself from getting a short
338 read out of pread(2).
340 - 'git http-push' had a few buffer overruns.
342 - Build dependency fixes to rebuild fetch.o when other headers
345 - git.el does not add duplicate sign-off lines.
347 - git-commit shows the full stat of the resulting commit, not
348 just about the files in the current directory, when run from
351 - "git-checkout -m '@{8 hours ago}'" had a funny failure from
354 - git-merge (hence git-pull) did not refuse fast-forwarding
355 when the working tree had local changes that would have
358 - a handful small fixes to gitweb.
360 - build procedure for user-manual is fixed not to require locally
361 installed stylesheets.
363 - "git commit $paths" on paths whose earlier contents were
364 already updated in the index were failing out.
369 - sliding mmap() inefficiently mmaped the same region of a
370 packfile with an access pattern that used objects in the
371 reverse order. This has been made more efficient.
