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,
36 without a separate invocation of "git lost-found" command.
38 - $GIT_WORK_TREE environment variable can be used together with
39 $GIT_DIR to work in a subdirectory of a working tree that is
40 not located at "$GIT_DIR/..".
42 - "git log" learned a new option "--follow", to follow
43 renaming history of a single file.
45 - "git-filter-branch" lets you rewrite the revision history of
46 the current branch, creating a new branch. You can specify a
47 number of filters to modify the commits, files and trees.
49 - "git-cvsserver" learned new options (--base-path, --export-all,
50 --strict-paths) inspired by git-daemon.
52 - "git-submodule" command helps you manage the projects from
53 the superproject that contain them.
55 - In addition to core.compression configuration option,
56 core.loosecompression and pack.compression options can
57 independently tweak zlib compression levels used for loose
58 and packed objects.
60 - "git-ls-tree -l" shows size of blobs pointed at by the
61 tree entries, similar to "/bin/ls -l".
63 - "git-rev-list" learned --regexp-ignore-case and
64 --extended-regexp options to tweak its matching logic used
65 for --grep fitering.
67 - "git-describe --contains" is a handier way to call more
68 obscure command "git-name-rev --tags".
70 - "git gc --aggressive" tells the command to spend more cycles
71 to optimize the repository harder.
73 - "git repack" learned a "window-memory" limit which
74 dynamically reduces the window size to stay within the
75 specified memory usage.
77 - "git repack" can be told to split resulting packs to avoid
78 exceeding limit specified with "--max-pack-size".
80 - "git fsck" gained --verbose option. This is really really
81 verbose but it might help you identify exact commit that is
82 corrupt in your repository.
84 - "git format-patch" learned --numbered-files option. This
85 may be useful for MH users.
87 - "git format-patch" learned format.subjectprefix configuration
88 variable, which serves the same purpose as "--subject-prefix"
89 option.
91 - "git tag -n -l" shows tag annotations while listing tags.
93 - "git cvsimport" can optionally use the separate-remote layout.
95 - "git blame" can be told to see through commits that change
96 whitespaces and indentation levels with "-w" option.
98 - "git send-email" can be told not to thread the messages when
99 sending out more than one patches.
101 - "git config" learned NUL terminated output format via -z to
102 help scripts.
104 - "git init -q" makes the command quieter.
106 * Updated behavior of existing commands.
108 - "git rm --cached" does not complain when removing a newly
109 added file from the index anymore.
111 - "git svn dcommit" retains local merge information.
113 - "git config" to set values also honors type flags like --bool
114 and --int.
116 - core.quotepath configuration can be used to make textual git
117 output to emit most of the characters in the path literally.
119 - "git mergetool" chooses its backend more wisely, taking
120 notice of its environment such as use of X, Gnome/KDE, etc.
122 - "gitweb" shows merge commits a lot nicer than before. The
123 default view uses more compact --cc format, while the UI
124 allows to choose normal diff with any parent.
126 - snapshot files "gitweb" creates from a repository at
127 $path/$project/.git are more useful. We use $project part
128 in the filename, which we used to discard.
130 - "git cvsimport" creates lightweight tags; there is no
131 interesting information we can record in an annotated tag,
132 and the handcrafted ones the old code created was not
133 properly formed anyway.
135 - "git-push" pretends that you immediately fetched back from
136 the remote by updating corresponding remote tracking
137 branches if you have any.
139 - The diffstat given after a merge (or a pull) honors the
140 color.diff configuration.
142 - "git-apply --whitespace=strip" removes blank lines added at
143 the end of the file.
145 - "git-fetch" over git native protocols with "-v" option shows
146 connection status, and the IP address of the other end, to
147 help diagnosing problems.
149 - We used to have core.legacyheaders configuration, when
150 set to false, allowed git to write loose objects in a format
151 that mimicks the format used by objects stored in packs. It
152 turns out that this was not so useful. Although we will
153 continue to read objects written in that format, we do not
154 honor that configuration anymore and create loose objects in
155 the legacy/traditional format.
157 - "--find-copies-harder" option to diff family can now be
158 spelled as "-C -C" for brevity.
160 - "git-mailsplit" (hence "git-am") can read from Maildir
161 formatted mailboxes.
163 - "git-cvsserver" does not barf upon seeing "cvs login"
164 request.
166 - "pack-objects" honors "delta" attribute set in
167 .gitattributes. It does not attempt to deltify blobs that
168 come from paths with delta attribute set to false.
170 - "new-workdir" script (in contrib) can now be used with a
171 bare repository.
173 - "git-mergetool" learned to use gvimdiff.
175 - "gitview" (in contrib) has a better blame interface.
177 - "git log" and friends did not handle a commit log message
178 that is larger than 16kB; they do now.
180 - "--pretty=oneline" output format for "git log" and friends
181 deals with "malformed" commit log messages that have more
182 than one lines in the first paragraph better. We used to
183 show the first line, cutting the title at mid-sentence; we
184 concatenate them into a single line and treat the result as
185 "oneline".
187 - "git p4import" has been demoted to contrib status. For
188 a superior option, checkout the git-p4 front end to
189 git-fast-import (also in contrib). The man page and p4
190 rpm have been removed as well.
192 * Builds
194 - old-style function definitions (most notably, a function
195 without parameter defined with "func()", not "func(void)")
196 have been eradicated.
198 * Performance Tweaks
200 - git-pack-objects avoids re-deltification cost by caching
201 small enough delta results it creates while looking for the
202 best delta candidates.
204 - git-pack-objects learned a new heuristcs to prefer delta
205 that is shallower in depth over the smallest delta
206 possible. This improves both overall packfile access
207 performance and packfile density.
209 - diff-delta code that is used for packing has been improved
210 to work better on big files.
212 - when there are more than one pack files in the repository,
213 the runtime used to try finding an object always from the
214 newest packfile; it now tries the same packfile as we found
215 the object requested the last time, which exploits the
216 locality of references.
218 - verifying pack contents done by "git fsck --full" got boost
219 by carefully choosing the order to verify objects in them.
222 Fixes since v1.5.2

231 Encode.pm Perl module.
