1 Git v1.7.11 Release Notes
2 =========================
4 Updates since v1.7.10
5 ---------------------
7 UI, Workflows & Features
9 * A new mode for push, "simple", which is a cross between "current"
10 and "upstream", has been introduced. "git push" without any refspec
11 will push the current branch out to the same name at the remote
12 repository only when it is set to track the branch with the same
13 name over there. The plan is to make this mode the new default
14 value when push.default is not configured.
16 * A couple of commands learned the "--column" option to produce
17 columnar output.
19 * A third-party tool "git subtree" is distributed in contrib/
21 * A remote helper that acts as a proxy and caches ssl session for the
22 https:// transport is added to the contrib/ area.
24 * Error messages given when @{u} is used for a branch without its
25 upstream configured have been clarified.
27 * Even with the "-q"uiet option, "checkout" used to report setting up
28 tracking. Also "branch" learned the "-q"uiet option to squelch
29 informational message.
31 * Your build platform may support hardlinks but you may prefer not to
32 use them, e.g. when installing to DESTDIR to make a tarball and
33 untarring on a filesystem that has poor support for hardlinks.
34 There is a Makefile option NO_INSTALL_HARDLINKS for you.
36 * The smart-http backend used to always override GIT_COMMITTER_*
37 variables with REMOTE_USER and REMOTE_ADDR, but these variables are
38 now preserved when set.
40 * "git am" learned the "--include" option, which is an opposite of
41 existing the "--exclude" option.
43 * When "git am -3" needs to fall back to an application of the patch
44 to a synthesized preimage followed by a 3-way merge, the paths that
45 needed such treatment are now reported to the end user, so that the
46 result in them can be eyeballed with extra care.
48 * The output from "diff/log --stat" used to always allocate 4 columns
49 to show the number of modified lines, but not anymore.
51 * "git difftool" learned the "--dir-diff" option to spawn external
52 diff tools that can compare two directory hierarchies at a time
53 after populating two temporary directories, instead of running an
54 instance of the external tool once per a file pair.
56 * The "fmt-merge-msg" command learned to list the primary contributors
57 involved in the side topic you are merging in a comment in the merge
58 commit template.
60 * "git rebase" learned to optionally keep commits that do not
61 introduce any change in the original history.
63 * "git push --recurse-submodules" learned to optionally look into the
64 histories of submodules bound to the superproject and push them
65 out.
67 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
68 based on the commit date.
70 * "gitweb" learned to highlight the patch it outputs even more.
72 Foreign Interface
74 * "git svn" used to die with unwanted SIGPIPE when talking with an HTTP
75 server that uses keep-alive.
77 * "git svn" learned to use platform specific authentication
78 providers, e.g. gnome-keyring, kwallet, etc.
80 * "git p4" has been moved out of the contrib/ area and has seen more
81 work on importing labels as tags from (and exporting tags as labels
82 to) p4.
84 Performance and Internal Implementation (please report possible regressions)
86 * Bash completion script (in contrib/) have been cleaned up to make
87 future work on it simpler.
89 * An experimental "version 4" format of the index file has been
90 introduced to reduce on-disk footprint and I/O overhead.
92 * "git archive" learned to produce its output without reading the
93 blob object it writes out in memory in its entirety.
95 * "git index-pack" that runs when fetching or pushing objects to
96 complete the packfile on the receiving end learned to use multiple
97 threads to do its job when available.
99 * The code to compute hash values for lines used by the internal diff
100 engine was optimized on little-endian machines, using the same
101 trick the kernel folks came up with.
103 * "git apply" had some memory leaks plugged.
105 * Setting up a revision traversal with many starting points was
106 inefficient as these were placed in a date-order priority queue
107 one-by-one. Now they are collected in the queue unordered first,
108 and sorted immediately before getting used.
110 * More lower-level commands learned to use the streaming API to read
111 from the object store without keeping everything in core.
113 * The weighting parameters to suggestion command name typo have been
114 tweaked, so that "git tags" will suggest "tag?" and not "stage?".
116 * Because "sh" on the user's PATH may be utterly broken on some
117 systems, run-command API now uses SHELL_PATH, not /bin/sh, when
118 spawning an external command (not applicable to Windows port).
120 * The API to iterate over the refs/ hierarchy has been tweaked to
121 allow walking only a subset of it more efficiently.
123 Also contains minor documentation updates and code clean-ups.
126 Fixes since v1.7.10
127 -------------------
129 Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
130 releases are contained in this release (see release notes to them for
131 details).
133 * "git submodule init" used to report "registered for path ..."
134 even for submodules that were registered earlier.
135 (cherry-pick c1c259e jl/submodule-report-new-path-once later to maint).
137 * "git diff --stat" used to fully count a binary file with modified
138 execution bits whose contents is unmodified, which was not quite
139 right.
