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 - The hunk header output from "git diff" family can be customized
25 with the attributes mechanism. See gitattributes(5) for details.
27 - "git stash" allows you to quickly save away your work in
28 progress and replay it later on an updated state.
30 - "git rebase" learned an "interactive" mode that let you
31 pick and reorder which commits to rebuild.
33 - "git fsck" can save its findings in $GIT_DIR/lost-found,
34 without a separate invocation of "git lost-found" command.
36 - $GIT_WORK_TREE environment variable can be used together with
37 $GIT_DIR to work in a subdirectory of a working tree that is
38 not located at "$GIT_DIR/..".
40 - "git log" learned a new option "--follow", to follow
41 renaming history of a single file.
43 - "git-filter-branch" lets you rewrite the revision history of
44 the current branch, creating a new branch. You can specify a
45 number of filters to modify the commits, files and trees.
47 - "git-cvsserver" learned new options (--base-path, --export-all,
48 --strict-paths) inspired by git-daemon.
50 - "git-submodule" command helps you manage the projects from
51 the superproject that contain them.
53 - In addition to core.compression configuration option,
54 core.loosecompression and pack.compression options can
55 independently tweak zlib compression levels used for loose
56 and packed objects.
58 - "git-ls-tree -l" shows size of blobs pointed at by the
59 tree entries, similar to "/bin/ls -l".
61 - "git-rev-list" learned --regexp-ignore-case and
62 --extended-regexp options to tweak its matching logic used
63 for --grep fitering.
65 - "git-describe --contains" is a handier way to call more
66 obscure command "git-name-rev --tags".
68 - "git gc --aggressive" tells the command to spend more cycles
69 to optimize the repository harder.
71 - "git repack" can be told to split resulting packs to avoid
72 exceeding limit specified with "--max-pack-size".
74 - "git fsck" gained --verbose option. This is really really
75 verbose but it might help you identify exact commit that is
76 corrupt in your repository.
78 - "git format-patch" learned --numbered-files option. This
79 may be useful for MH users.
81 - "git format-patch" learned format.subjectprefix configuration
82 variable, which serves the same purpose as "--subject-prefix"
83 option.
85 - "git tag -n -l" shows tag annotations while listing tags.
87 - "git cvsimport" can optionally use the separate-remote layout.
89 - "git blame" can be told to see through commits that change
90 whitespaces and indentation levels with "-w" option.
92 - "git send-email" can be told not to thread the messages when
93 sending out more than one patches.
95 - "git config" learned NUL terminated output format via -z to
96 help scripts.
98 - "git init -q" makes the command quieter.
100 * Updated behavior of existing commands.
102 - "git svn dcommit" retains local merge information.
104 - "git config" to set values also honors type flags like --bool
105 and --int.
107 - core.quotepath configuration can be used to make textual git
108 output to emit most of the characters in the path literally.
110 - "git mergetool" chooses its backend more wisely, taking
111 notice of its environment such as use of X, Gnome/KDE, etc.
113 - "gitweb" shows merge commits a lot nicer than before. The
114 default view uses more compact --cc format, while the UI
115 allows to choose normal diff with any parent.
117 - snapshot files "gitweb" creates from a repository at
118 $path/$project/.git are more useful. We use $project part
119 in the filename, which we used to discard.
121 - "git cvsimport" creates lightweight tags; there is no
122 interesting information we can record in an annotated tag,
123 and the handcrafted ones the old code created was not
124 properly formed anyway.
126 - "git-push" pretends that you immediately fetched back from
127 the remote by updating corresponding remote tracking
128 branches if you have any.
130 - The diffstat given after a merge (or a pull) honors the
131 color.diff configuration.
133 - "git-apply --whitespace=strip" removes blank lines added at
134 the end of the file.
136 - "git-fetch" over git native protocols with "-v" option shows
137 connection status, and the IP address of the other end, to
138 help diagnosing problems.
140 - We used to have core.legacyheaders configuration, when
141 set to false, allowed git to write loose objects in a format
142 that mimicks the format used by objects stored in packs. It
143 turns out that this was not so useful. Although we will
144 continue to read objects written in that format, we do not
145 honor that configuration anymore and create loose objects in
146 the legacy/traditional format.
148 - "--find-copies-harder" option to diff family can now be
149 spelled as "-C -C" for brevity.
151 - "git-mailsplit" (hence "git-am") can read from Maildir
152 formatted mailboxes.
154 - "git-cvsserver" does not barf upon seeing "cvs login"
155 request.
157 - "pack-objects" honors "delta" attribute set in
158 .gitattributes. It does not attempt to deltify blobs that
159 come from paths with delta attribute set to false.
161 - "new-workdir" script (in contrib) can now be used with a
162 bare repository.
164 - "git-mergetool" learned to use gvimdiff.
166 - "gitview" (in contrib) has a better blame interface.
168 - "git log" and friends did not handle a commit log message
169 that is larger than 16kB; they do now.
171 - "--pretty=oneline" output format for "git log" and friends
172 deals with "malformed" commit log messages that have more
173 than one lines in the first paragraph better. We used to
174 show the first line, cutting the title at mid-sentence; we
175 concatenate them into a single line and treat the result as
176 "oneline".
178 * Builds
180 - old-style function definitions (most notably, a function
181 without parameter defined with "func()", not "func(void)")
182 have been eradicated.
184 * Performance Tweaks
186 - git-pack-objects avoids re-deltification cost by caching
187 small enough delta results it creates while looking for the
188 best delta candidates.
190 - git-pack-objects learned a new heuristcs to prefer delta
191 that is shallower in depth over the smallest delta
192 possible. This improves both overall packfile access
193 performance and packfile density.
195 - diff-delta code that is used for packing has been improved
196 to work better on big files.
198 - when there are more than one pack files in the repository,
199 the runtime used to try finding an object always from the
200 newest packfile; it now tries the same packfile as we found
201 the object requested the last time, which exploits the
202 locality of references.
204 - verifying pack contents done by "git fsck --full" got boost
205 by carefully choosing the order to verify objects in them.
