1 GIT v1.5.3 Release Notes
2 ========================
4 Updates since v1.5.2
5 --------------------
7 * The commit walkers other than http are officially deprecated,
8 but still supported for now.
10 * The submodule support has Porcelain layer.
12 Note that the current submodule support is minimal and this is
13 deliberately so. A design decision we made is that operations
14 at the supermodule level do not recurse into submodules by
15 default. The expectation is that later we would add a
16 mechanism to tell git which submodules the user is interested
17 in, and this information might be used to determine the
18 recursive behaviour of certain commands (e.g. "git checkout"
19 and "git diff"), but currently we haven't agreed on what that
20 mechanism should look like. Therefore, if you use submodules,
21 you would probably need "git submodule update" on the
22 submodules you care about after running a "git checkout" at
23 the supermodule level.
25 * There are a handful pack-objects changes to help you cope better
26 with repositories with pathologically large blobs in them.
28 * For people who need to import from Perforce, a front-end for
29 fast-import is in contrib/fast-import/.
31 * Comes with git-gui 0.8.1.
33 * Comes with updated gitk.
35 * New commands and options.
37 - "git log --date=<format>" can use more formats: iso8601, rfc2822.
39 - The hunk header output from "git diff" family can be customized
40 with the attributes mechanism. See gitattributes(5) for details.
42 - "git stash" allows you to quickly save away your work in
43 progress and replay it later on an updated state.
45 - "git rebase" learned an "interactive" mode that let you
46 pick and reorder which commits to rebuild.
48 - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
49 separate invocation of "git lost-found" command. The blobs stored by
50 lost-found are stored in plain format to allow you to grep in them.
52 - $GIT_WORK_TREE environment variable can be used together with
53 $GIT_DIR to work in a subdirectory of a working tree that is
54 not located at "$GIT_DIR/..".
56 - Giving "--file=<file>" option to "git config" is the same as
57 running the command with GIT_CONFIG=<file> environment.
59 - "git log" learned a new option "--follow", to follow
60 renaming history of a single file.
62 - "git filter-branch" lets you rewrite the revision history of
63 specified branches. You can specify a number of filters to
64 modify the commits, files and trees.
66 - "git cvsserver" learned new options (--base-path, --export-all,
67 --strict-paths) inspired by "git daemon".
69 - "git daemon --base-path-relaxed" can help migrating a repository URL
70 that did not use to use --base-path to use --base-path.
72 - "git commit" can use "-t templatefile" option and commit.template
73 configuration variable to prime the commit message given to you in the
74 editor.
76 - "git submodule" command helps you manage the projects from
77 the superproject that contain them.
79 - In addition to core.compression configuration option,
80 core.loosecompression and pack.compression options can
81 independently tweak zlib compression levels used for loose
82 and packed objects.
84 - "git ls-tree -l" shows size of blobs pointed at by the
85 tree entries, similar to "/bin/ls -l".
87 - "git rev-list" learned --regexp-ignore-case and
88 --extended-regexp options to tweak its matching logic used
89 for --grep fitering.
91 - "git describe --contains" is a handier way to call more
92 obscure command "git name-rev --tags".
94 - "git gc --aggressive" tells the command to spend more cycles
95 to optimize the repository harder.
97 - "git repack" learned a "window-memory" limit which
98 dynamically reduces the window size to stay within the
99 specified memory usage.
101 - "git repack" can be told to split resulting packs to avoid
102 exceeding limit specified with "--max-pack-size".
104 - "git fsck" gained --verbose option. This is really really
105 verbose but it might help you identify exact commit that is
106 corrupt in your repository.
108 - "git format-patch" learned --numbered-files option. This
109 may be useful for MH users.
111 - "git format-patch" learned format.subjectprefix configuration
112 variable, which serves the same purpose as "--subject-prefix"
113 option.
115 - "git tag -n -l" shows tag annotations while listing tags.
117 - "git cvsimport" can optionally use the separate-remote layout.
119 - "git blame" can be told to see through commits that change
120 whitespaces and indentation levels with "-w" option.
122 - "git send-email" can be told not to thread the messages when
123 sending out more than one patches.
125 - "git config" learned NUL terminated output format via -z to
126 help scripts.
128 - "git add" learned "--refresh <paths>..." option to selectively refresh
129 the cached stat information.
131 - "git init -q" makes the command quieter.
133 - "git -p command" now has a cousin of opposite sex, "git --no-pager
134 command".
136 * Updated behavior of existing commands.
138 - "gitweb" can offer multiple snapshot formats.
140 ***NOTE*** Unfortunately, this changes the format of the
141 $feature{snapshot}{default} entry in the per-site
142 configuration file 'gitweb_config.perl'. It used to be a
143 three-element tuple that describe a single format; with the
144 new configuration item format, you only have to say the name
145 of the format ('tgz', 'tbz2' or 'zip'). Please update the
146 your configuration file accordingly.
148 - "git clone" uses -l (hardlink files under .git) by default when
149 cloning locally.
151 - "git bundle create" can now create a bundle without negative refs,
152 i.e. "everything since the beginning up to certain points".
154 - "git diff" (but not the plumbing level "git diff-tree") now
155 recursively descends into trees by default.
157 - "git diff" does not show differences that come only from
158 stat-dirtiness in the form of "diff --git" header anymore. When
159 generating a textual diff, it shows a warning message at the end.
161 - The editor to use with many interactive commands can be
162 overridden with GIT_EDITOR environment variable, or if it
163 does not exist, with core.editor configuration variable. As
164 before, if you have neither, environment variables VISUAL
165 and EDITOR are consulted in this order, and then finally we
166 fall back on "vi".
168 - "git rm --cached" does not complain when removing a newly
169 added file from the index anymore.
171 - Options to "git log" to affect how --grep/--author options look for
172 given strings now have shorter abbreviations. -i is for ignore case,
173 and -E is for extended regexp.
175 - "git log" learned --log-size to show the number of bytes in
176 the log message part of the output to help qgit.
178 - "git svn dcommit" retains local merge information.
180 - "git svnimport" allows an empty string to be specified as the
181 trunk/ directory. This is necessary to suck data from a SVN
182 repository that doe not have trunk/ branches/ and tags/ organization
183 at all.
185 - "git config" to set values also honors type flags like --bool
186 and --int.
188 - core.quotepath configuration can be used to make textual git
189 output to emit most of the characters in the path literally.
191 - "git mergetool" chooses its backend more wisely, taking
192 notice of its environment such as use of X, Gnome/KDE, etc.
194 - "gitweb" shows merge commits a lot nicer than before. The
195 default view uses more compact --cc format, while the UI
196 allows to choose normal diff with any parent.
198 - snapshot files "gitweb" creates from a repository at
199 $path/$project/.git are more useful. We use $project part
200 in the filename, which we used to discard.
202 - "git cvsimport" creates lightweight tags; there is no
203 interesting information we can record in an annotated tag,
204 and the handcrafted ones the old code created was not
205 properly formed anyway.
207 - "git push" pretends that you immediately fetched back from
208 the remote by updating corresponding remote tracking
209 branches if you have any.
211 - The diffstat given after a merge (or a pull) honors the
212 color.diff configuration.
214 - "git commit --amend" is now compatible with various message source
215 options such as -m/-C/-c/-F.
217 - "git apply --whitespace=strip" removes blank lines added at
218 the end of the file.
220 - "git fetch" over git native protocols with "-v" option shows
221 connection status, and the IP address of the other end, to
222 help diagnosing problems.
224 - We used to have core.legacyheaders configuration, when
225 set to false, allowed git to write loose objects in a format
226 that mimicks the format used by objects stored in packs. It
227 turns out that this was not so useful. Although we will
228 continue to read objects written in that format, we do not
229 honor that configuration anymore and create loose objects in
230 the legacy/traditional format.
232 - "--find-copies-harder" option to diff family can now be
233 spelled as "-C -C" for brevity.
235 - "git mailsplit" (hence "git am") can read from Maildir
236 formatted mailboxes.
238 - "git cvsserver" does not barf upon seeing "cvs login"
239 request.
241 - "pack-objects" honors "delta" attribute set in
242 .gitattributes. It does not attempt to deltify blobs that
243 come from paths with delta attribute set to false.
245 - "new-workdir" script (in contrib) can now be used with a
246 bare repository.
248 - "git mergetool" learned to use gvimdiff.
250 - "gitview" (in contrib) has a better blame interface.
252 - "git log" and friends did not handle a commit log message
253 that is larger than 16kB; they do now.
255 - "--pretty=oneline" output format for "git log" and friends
256 deals with "malformed" commit log messages that have more
257 than one lines in the first paragraph better. We used to
258 show the first line, cutting the title at mid-sentence; we
259 concatenate them into a single line and treat the result as
260 "oneline".
262 - "git p4import" has been demoted to contrib status. For
263 a superior option, checkout the "git p4" front end to
264 "git fast-import" (also in contrib). The man page and p4
265 rpm have been removed as well.
267 - "git mailinfo" (hence "am") now tries to see if the message
268 is in utf-8 first, instead of assuming iso-8859-1, if
269 incoming e-mail does not say what encoding it is in.
271 * Builds
273 - old-style function definitions (most notably, a function
274 without parameter defined with "func()", not "func(void)")
275 have been eradicated.
277 - "git tag" and "git verify-tag" have been rewritten in C.
279 * Performance Tweaks
281 - "git pack-objects" avoids re-deltification cost by caching
282 small enough delta results it creates while looking for the
283 best delta candidates.
285 - "git pack-objects" learned a new heuristcs to prefer delta
286 that is shallower in depth over the smallest delta
287 possible. This improves both overall packfile access
288 performance and packfile density.
290 - diff-delta code that is used for packing has been improved
291 to work better on big files.
293 - when there are more than one pack files in the repository,
294 the runtime used to try finding an object always from the
295 newest packfile; it now tries the same packfile as we found
296 the object requested the last time, which exploits the
297 locality of references.
299 - verifying pack contents done by "git fsck --full" got boost
300 by carefully choosing the order to verify objects in them.
302 - "git read-tree -m" to read into an already populated index
303 has been optimized vastly. The effect of this can be seen
304 when switching branches that have differences in only a
305 handful paths.
307 - "git commit paths..." has also been optimized.
