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 * There are a handful pack-objects changes to help you cope better
13 with repositories with pathologically large blobs in them.
15 * For people who need to import from Perforce, a front-end for
16 fast-import is in contrib/fast-import/.
18 * Comes with git-gui 0.8.0.
20 * Comes with updated gitk.
22 * New commands and options.
24 - "git log --date=<format>" can use more formats: iso8601, rfc2822.
26 - The hunk header output from "git diff" family can be customized
27 with the attributes mechanism. See gitattributes(5) for details.
29 - "git stash" allows you to quickly save away your work in
30 progress and replay it later on an updated state.
32 - "git rebase" learned an "interactive" mode that let you
33 pick and reorder which commits to rebuild.
35 - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
36 separate invocation of "git lost-found" command. The blobs stored by
37 lost-found are stored in plain format to allow you to grep in them.
39 - $GIT_WORK_TREE environment variable can be used together with
40 $GIT_DIR to work in a subdirectory of a working tree that is
41 not located at "$GIT_DIR/..".
43 - "git log" learned a new option "--follow", to follow
44 renaming history of a single file.
46 - "git-filter-branch" lets you rewrite the revision history of
47 the current branch, creating a new branch. You can specify a
48 number of filters to modify the commits, files and trees.
50 - "git-cvsserver" learned new options (--base-path, --export-all,
51 --strict-paths) inspired by git-daemon.
53 - "git-commit" can use "-t templatefile" option and commit.template
54 configuration variable to prime the commit message given to you in the
55 editor.
57 - "git-submodule" command helps you manage the projects from
58 the superproject that contain them.
60 - In addition to core.compression configuration option,
61 core.loosecompression and pack.compression options can
62 independently tweak zlib compression levels used for loose
63 and packed objects.
65 - "git-ls-tree -l" shows size of blobs pointed at by the
66 tree entries, similar to "/bin/ls -l".
68 - "git-rev-list" learned --regexp-ignore-case and
69 --extended-regexp options to tweak its matching logic used
70 for --grep fitering.
72 - "git-describe --contains" is a handier way to call more
73 obscure command "git-name-rev --tags".
75 - "git gc --aggressive" tells the command to spend more cycles
76 to optimize the repository harder.
78 - "git repack" learned a "window-memory" limit which
79 dynamically reduces the window size to stay within the
80 specified memory usage.
82 - "git repack" can be told to split resulting packs to avoid
83 exceeding limit specified with "--max-pack-size".
85 - "git fsck" gained --verbose option. This is really really
86 verbose but it might help you identify exact commit that is
87 corrupt in your repository.
89 - "git format-patch" learned --numbered-files option. This
90 may be useful for MH users.
92 - "git format-patch" learned format.subjectprefix configuration
93 variable, which serves the same purpose as "--subject-prefix"
94 option.
96 - "git tag -n -l" shows tag annotations while listing tags.
98 - "git cvsimport" can optionally use the separate-remote layout.
100 - "git blame" can be told to see through commits that change
101 whitespaces and indentation levels with "-w" option.
103 - "git send-email" can be told not to thread the messages when
104 sending out more than one patches.
106 - "git config" learned NUL terminated output format via -z to
107 help scripts.
109 - "git init -q" makes the command quieter.
111 * Updated behavior of existing commands.
113 - "gitweb" can offer multiple snapshot formats.
115 ***NOTE*** Unfortunately, this changes the format of the
116 $feature{snapshot}{default} entry in the per-site
117 configuration file 'gitweb_config.perl'. It used to be a
118 three-element tuple that describe a single format; with the
119 new configuration item format, you only have to say the name
120 of the format ('tgz', 'tbz2' or 'zip'). Please update the
121 your configuration file accordingly.
123 - The editor to use with many interactive commands can be
124 overridden with GIT_EDITOR environment variable, or if it
125 does not exist, with core.editor configuration variable. As
126 before, if you have neither, environment variables VISUAL
127 and EDITOR are consulted in this order, and then finally we
128 fall back on "vi".
130 - "git rm --cached" does not complain when removing a newly
131 added file from the index anymore.
133 - Options to "git log" to affect how --grep/--author options look for
134 given strings now have shorter abbreviations. -i is for ignore case,
135 and -E is for extended regexp.
137 - "git svn dcommit" retains local merge information.
139 - "git config" to set values also honors type flags like --bool
140 and --int.
142 - core.quotepath configuration can be used to make textual git
143 output to emit most of the characters in the path literally.
145 - "git mergetool" chooses its backend more wisely, taking
146 notice of its environment such as use of X, Gnome/KDE, etc.
148 - "gitweb" shows merge commits a lot nicer than before. The
149 default view uses more compact --cc format, while the UI
150 allows to choose normal diff with any parent.
152 - snapshot files "gitweb" creates from a repository at
153 $path/$project/.git are more useful. We use $project part
154 in the filename, which we used to discard.
156 - "git cvsimport" creates lightweight tags; there is no
157 interesting information we can record in an annotated tag,
158 and the handcrafted ones the old code created was not
159 properly formed anyway.
161 - "git-push" pretends that you immediately fetched back from
162 the remote by updating corresponding remote tracking
163 branches if you have any.
165 - The diffstat given after a merge (or a pull) honors the
166 color.diff configuration.
168 - "git-apply --whitespace=strip" removes blank lines added at
169 the end of the file.
171 - "git-fetch" over git native protocols with "-v" option shows
172 connection status, and the IP address of the other end, to
173 help diagnosing problems.
175 - We used to have core.legacyheaders configuration, when
176 set to false, allowed git to write loose objects in a format
177 that mimicks the format used by objects stored in packs. It
178 turns out that this was not so useful. Although we will
179 continue to read objects written in that format, we do not
180 honor that configuration anymore and create loose objects in
181 the legacy/traditional format.
183 - "--find-copies-harder" option to diff family can now be
184 spelled as "-C -C" for brevity.
186 - "git-mailsplit" (hence "git-am") can read from Maildir
187 formatted mailboxes.
189 - "git-cvsserver" does not barf upon seeing "cvs login"
190 request.
192 - "pack-objects" honors "delta" attribute set in
193 .gitattributes. It does not attempt to deltify blobs that
194 come from paths with delta attribute set to false.
196 - "new-workdir" script (in contrib) can now be used with a
197 bare repository.
199 - "git-mergetool" learned to use gvimdiff.
201 - "gitview" (in contrib) has a better blame interface.
203 - "git log" and friends did not handle a commit log message
204 that is larger than 16kB; they do now.
206 - "--pretty=oneline" output format for "git log" and friends
207 deals with "malformed" commit log messages that have more
208 than one lines in the first paragraph better. We used to
209 show the first line, cutting the title at mid-sentence; we
210 concatenate them into a single line and treat the result as
211 "oneline".
213 - "git p4import" has been demoted to contrib status. For
214 a superior option, checkout the git-p4 front end to
215 git-fast-import (also in contrib). The man page and p4
216 rpm have been removed as well.
218 - "git mailinfo" (hence "am") now tries to see if the message
219 is in utf-8 first, instead of assuming iso-8859-1, if
220 incoming e-mail does not say what encoding it is in.
222 * Builds
224 - old-style function definitions (most notably, a function
225 without parameter defined with "func()", not "func(void)")
226 have been eradicated.
228 * Performance Tweaks
230 - git-pack-objects avoids re-deltification cost by caching
231 small enough delta results it creates while looking for the
232 best delta candidates.
234 - git-pack-objects learned a new heuristcs to prefer delta
235 that is shallower in depth over the smallest delta
236 possible. This improves both overall packfile access
237 performance and packfile density.
239 - diff-delta code that is used for packing has been improved
240 to work better on big files.
242 - when there are more than one pack files in the repository,
243 the runtime used to try finding an object always from the
244 newest packfile; it now tries the same packfile as we found
245 the object requested the last time, which exploits the
246 locality of references.
248 - verifying pack contents done by "git fsck --full" got boost
249 by carefully choosing the order to verify objects in them.
