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 * Error messages given when @{u} is used for a branch without its
22 upstream configured have been clatified.
24 * Even with "-q"uiet option, "checkout" used to report setting up
25 tracking. Also "branch" learned the "-q"uiet option to squelch
26 informational message.
28 * The smart-http backend used to always override GIT_COMMITTER_*
29 variables with REMOTE_USER and REMOTE_ADDR, but these variables are
30 now preserved when set.
32 * "include.path" mechanism of the configuration files learned to
33 understand "~/path" and "~user/path".
35 * "git am" learned the "--include" option, which is an opposite of
36 existing the "--exclude" option.
38 * When "git am -3" needs to fall back to an application to a
39 synthesized preimage followed by a 3-way merge, the paths that
40 needed such treatment are now reported to the end user, so that the
41 result in them can be eyeballed with extra care.
43 * The output from "diff/log --stat" used to always allocate 4 columns
44 to show the number of modified lines, but not anymore.
46 * "git difftool" learned the "--dir-diff" option to spawn external
47 diff tools that can compare two directory hierarchies at a time
48 after populating two temporary directories, instead of running an
49 instance of the external tool once per a file pair.
51 * The "fmt-merge-msg" command learns to list the primary contributors
52 involved in the side topic you are merging.
54 * The cases "git push" fails due to non-ff can be broken into three
55 categories; each case is given a separate advise message.
57 * "git rebase" learned to optionally keep commits that do not
58 introduce any change in the original history.
60 * "git push --recurse-submodules" learned to optionally look into the
61 histories of submodules bound to the superproject and push them
62 out.
64 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
65 based on the commit date.
67 * "gitweb" learned to highlight the patch it outputs even more.
69 Foreign Interface
71 * "git svn" used to die with unwanted SIGPIPE when talking with HTTP
72 server that uses keep-alive.
74 * "git svn" learned to use platform specific authentication
75 providers, e.g. gnome-keyring, kwallet, etc.
77 * "git p4" has been moved out of contrib/ area and has seen more work
78 on importing labels as tags from (and exporting tags as labels to)
79 p4.
81 Performance and Internal Implementation (please report possible regressions)
83 * An experimental "version 4" format of the index file has been
84 introduced to reduce on-disk footprint and I/O overhead.
86 * The code to compute hash values for lines used by the internal diff
87 engine was optimized on little-endian machines, using the same
88 trick the kernel folks came up with.
90 * "git apply" had some memory leaks plugged.
92 * "git repack" used to write out unreachable objects as loose objects
93 when repacking, even if such loose objects will immediately pruned
94 due to its age.
96 * Setting up a revision traversal with many starting points was
97 inefficient as these were placed in a date-order priority queue
98 one-by-one. Now they are collected in the queue unordered first,
99 and sorted immediately before getting used.
101 * "git rev-parse --show-prefix" used to emit nothing when run at the
102 top-level of the working tree, but now it gives a blank line.
104 * Minor memory leak during unpack_trees (hence "merge" and "checkout"
105 to check out another branch) has been plugged.
107 * More lower-level commands learned to use the streaming API to read
108 from the object store without keeping everything in core.
110 * Because "sh" on the user's PATH may be utterly broken on some
111 systems, run-command API now uses SHELL_PATH, not /bin/sh, when
112 spawning an external command (not applicable to Windows port).
114 * The API to iterate over refs/ hierarchy has been tweaked to allow
115 walking only a subset of it more efficiently.
117 Also contains minor documentation updates and code clean-ups.
120 Fixes since v1.7.10
121 -------------------
123 Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
124 releases are contained in this release (see release notes to them for
125 details).
127 * "git diff --stat" used to fully count a binary file with modified
128 execution bits whose contents is unmodified, which was not quite
129 right.
131 * "log -z --pretty=tformat:..." did not terminate each record with
132 NUL. The fix is not entirely correct when the output also asks for
133 --patch and/or --stat, though.
134 (merge fafd382 jk/maint-tformat-with-z later to maint).
136 * "git push" over smart-http lost progress output a few releases ago.
137 (merge e304aeb jk/maint-push-progress later to maint).
139 * A contrib script "rerere-train" did not work out of the box unless
140 user futzed with her $PATH.
141 (merge 53876fc jc/rerere-train later to maint).
143 * "log --graph" was not very friendly with "--stat" option and its
144 output had line breaks at wrong places.
145 (merge bafa16e lp/diffstat-with-graph later to maint).
