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 stash" allows you to quickly save away your work in
25 progress and replay it later on an updated state.
27 - "git rebase" learned an "interactive" mode that let you
28 pick and reorder which commits to rebuild.
30 - "git fsck" can save its findings in $GIT_DIR/lost-found,
31 without a separate invocation of "git lost-found" command.
33 - $GIT_WORK_TREE environment variable can be used together with
34 $GIT_DIR to work in a subdirectory of a working tree that is
35 not located at "$GIT_DIR/..".
37 - "git log" learned a new option "--follow", to follow
38 renaming history of a single file.
40 - "git-filter-branch" lets you rewrite the revision history of
41 the current branch, creating a new branch. You can specify a
42 number of filters to modify the commits, files and trees.
44 - "git-cvsserver" learned new options (--base-path, --export-all,
45 --strict-paths) inspired by git-daemon.
47 - "git-submodule" command helps you manage the projects from
48 the superproject that contain them.
50 - In addition to core.compression configuration option,
51 core.loosecompression and pack.compression options can
52 independently tweak zlib compression levels used for loose
53 and packed objects.
55 - "git-ls-tree -l" shows size of blobs pointed at by the
56 tree entries, similar to "/bin/ls -l".
58 - "git-rev-list" learned --regexp-ignore-case and
59 --extended-regexp options to tweak its matching logic used
60 for --grep fitering.
62 - "git-describe --contains" is a handier way to call more
63 obscure command "git-name-rev --tags".
65 - "git gc --aggressive" tells the command to spend more cycles
66 to optimize the repository harder.
68 - "git repack" can be told to split resulting packs to avoid
69 exceeding limit specified with "--max-pack-size".
71 - "git fsck" gained --verbose option. This is really really
72 verbose but it might help you identify exact commit that is
73 corrupt in your repository.
75 - "git format-patch" learned --numbered-files option. This
76 may be useful for MH users.
78 - "git format-patch" learned format.subjectprefix configuration
79 variable, which serves the same purpose as "--subject-prefix"
80 option.
82 - "git tag -n -l" shows tag annotations while listing tags.
84 - "git cvsimport" can optionally use the separate-remote layout.
86 - "git blame" can be told to see through commits that change
87 whitespaces and indentation levels with "-w" option.
89 - "git send-email" can be told not to thread the messages when
90 sending out more than one patches.
92 - "git config" learned NUL terminated output format via -z to
93 help scripts.
95 - "git init -q" makes the command quieter.
97 * Updated behavior of existing commands.
99 - "git svn dcommit" retains local merge information.
101 - "git config" to set values also honors type flags like --bool
102 and --int.
104 - core.quotepath configuration can be used to make textual git
105 output to emit most of the characters in the path literally.
107 - "git mergetool" chooses its backend more wisely, taking
108 notice of its environment such as use of X, Gnome/KDE, etc.
110 - "gitweb" shows merge commits a lot nicer than before. The
111 default view uses more compact --cc format, while the UI
112 allows to choose normal diff with any parent.
114 - snapshot files "gitweb" creates from a repository at
115 $path/$project/.git are more useful. We use $project part
116 in the filename, which we used to discard.
118 - "git cvsimport" creates lightweight tags; there is no
119 interesting information we can record in an annotated tag,
120 and the handcrafted ones the old code created was not
121 properly formed anyway.
123 - "git-push" pretends that you immediately fetched back from
124 the remote by updating corresponding remote tracking
125 branches if you have any.
127 - The diffstat given after a merge (or a pull) honors the
128 color.diff configuration.
130 - "git-apply --whitespace=strip" removes blank lines added at
131 the end of the file.
133 - "git-fetch" over git native protocols with "-v" option shows
134 connection status, and the IP address of the other end, to
135 help diagnosing problems.
137 - We used to have core.legacyheaders configuration, when
138 set to false, allowed git to write loose objects in a format
139 that mimicks the format used by objects stored in packs. It
140 turns out that this was not so useful. Although we will
141 continue to read objects written in that format, we do not
142 honor that configuration anymore and create loose objects in
143 the legacy/traditional format.
145 - "--find-copies-harder" option to diff family can now be
146 spelled as "-C -C" for brevity.
148 - "git-mailsplit" (hence "git-am") can read from Maildir
149 formatted mailboxes.
151 - "git-cvsserver" does not barf upon seeing "cvs login"
152 request.
154 - "pack-objects" honors "delta" attribute set in
155 .gitattributes. It does not attempt to deltify blobs that
156 come from paths with delta attribute set to false.
158 - "new-workdir" script (in contrib) can now be used with a
159 bare repository.
161 - "git-mergetool" learned to use gvimdiff.
163 - "gitview" (in contrib) has a better blame interface.
165 - "git log" and friends did not handle a commit log message
166 that is larger than 16kB; they do now.
168 - "--pretty=oneline" output format for "git log" and friends
169 deals with "malformed" commit log messages that have more
170 than one lines in the first paragraph better. We used to
171 show the first line, cutting the title at mid-sentence; we
172 concatenate them into a single line and treat the result as
173 "oneline".
175 * Builds
177 - old-style function definitions (most notably, a function
178 without parameter defined with "func()", not "func(void)")
179 have been eradicated.
181 * Performance Tweaks
183 - git-pack-objects avoids re-deltification cost by caching
184 small enough delta results it creates while looking for the
185 best delta candidates.
187 - diff-delta code that is used for packing has been improved
188 to work better on big files.
190 - when there are more than one pack files in the repository,
191 the runtime used to try finding an object always from the
192 newest packfile; it now tries the same packfile as we found
193 the object requested the last time, which exploits the
194 locality of references.
196 - verifying pack contents done by "git fsck --full" got boost
197 by carefully choosing the order to verify objects in them.
