1 Git v1.7.7 Release Notes
2 ========================
4 Updates since v1.7.6
5 --------------------
7 * The scripting part of the codebase is getting prepared for i18n/l10n.
9 * Interix, Cygwin and Minix ports got updated.
11 * Various updates to git-p4 (in contrib/), fast-import, and git-svn.
13 * Gitweb learned to read from /etc/gitweb-common.conf when it exists,
14 before reading from gitweb_config.perl or from /etc/gitweb.conf
15 (this last one is read only when per-repository gitweb_config.perl
16 does not exist).
18 * Various codepaths that invoked zlib deflate/inflate assumed that these
19 functions can compress or uncompress more than 4GB data in one call on
20 platforms with 64-bit long, which has been corrected.
22 * Git now recognizes loose objects written by other implementations that
23 use a non-standard window size for zlib deflation (e.g. Agit running on
24 Android with 4kb window). We used to reject anything that was not
25 deflated with 32kb window.
27 * Interaction between the use of pager and coloring of the output has
28 been improved, especially when a command that is not built-in was
29 involved.
31 * "git am" learned to pass the "--exclude=<path>" option through to underlying
32 "git apply".
34 * You can now feed many empty lines before feeding an mbox file to
35 "git am".
37 * "git archive" can be told to pass the output to gzip compression and
38 produce "archive.tar.gz".
40 * "git bisect" can be used in a bare repository (provided that the test
41 you perform per each iteration does not need a working tree, of
42 course).
44 * The length of abbreviated object names in "git branch -v" output
45 now honors the core.abbrev configuration variable.
47 * "git check-attr" can take relative paths from the command line.
49 * "git check-attr" learned an "--all" option to list the attributes for a
50 given path.
52 * "git checkout" (both the code to update the files upon checking out a
53 different branch and the code to checkout a specific set of files) learned
54 to stream the data from object store when possible, without having to
55 read the entire contents of a file into memory first. An earlier round
56 of this code that is not in any released version had a large leak but
57 now it has been plugged.
59 * "git clone" can now take a "--config key=value" option to set the
60 repository configuration options that affect the initial checkout.
62 * "git commit <paths>..." now lets you feed relative pathspecs that
63 refer to outside your current subdirectory.
65 * "git diff --stat" learned a --stat-count option to limit the output of
66 a diffstat report.
68 * "git diff" learned a "--histogram" option to use a different diff
69 generation machinery stolen from jgit, which might give better
70 performance.
72 * "git diff" had a weird worst case behaviour that can be triggered
73 when comparing files with potentially many places that could match.
75 * "git fetch", "git push" and friends no longer show connection
76 errors for addresses that couldn't be connected to when at least one
77 address succeeds (this is arguably a regression but a deliberate
78 one).
80 * "git grep" learned "--break" and "--heading" options, to let users mimic
81 the output format of "ack".
83 * "git grep" learned a "-W" option that shows wider context using the same
84 logic used by "git diff" to determine the hunk header.
86 * Invoking the low-level "git http-fetch" without "-a" option (which
87 git itself never did--normal users should not have to worry about
88 this) is now deprecated.
90 * The "--decorate" option to "git log" and its family learned to
91 highlight grafted and replaced commits.
93 * "git rebase master topci" no longer spews usage hints after giving
94 the "fatal: no such branch: topci" error message.
96 * The recursive merge strategy implementation got a fairly large
97 fix for many corner cases that may rarely happen in real world
98 projects (it has been verified that none of the 16000+ merges in
99 the Linux kernel history back to v2.6.12 is affected with the
100 corner case bugs this update fixes).
102 * "git stash" learned an "--include-untracked option".
104 * "git submodule update" used to stop at the first error updating a
105 submodule; it now goes on to update other submodules that can be
106 updated, and reports the ones with errors at the end.
108 * "git push" can be told with the "--recurse-submodules=check" option to
109 refuse pushing of the supermodule, if any of its submodules'
110 commits hasn't been pushed out to their remotes.
112 * "git upload-pack" and "git receive-pack" learned to pretend that only a
113 subset of the refs exist in a repository. This may help a site to
114 put many tiny repositories into one repository (this would not be
115 useful for larger repositories as repacking would be problematic).
117 * "git verify-pack" has been rewritten to use the "index-pack" machinery
118 that is more efficient in reading objects in packfiles.
120 * test scripts for gitweb tried to run even when CGI-related perl modules
121 are not installed; they now exit early when the latter are unavailable.
123 Also contains various documentation updates and minor miscellaneous
124 changes.
127 Fixes since v1.7.6
128 ------------------
130 Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
131 included in this release.
133 * "git branch -m" and "git checkout -b" incorrectly allowed the tip
134 of the branch that is currently checked out updated.
