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 * Your build platform may support hardlinks but you may prefer not to
29 use them, e.g. when installing to DESTDIR to make a tarball and
30 untarring on a filesystem that has poor support for hardlinks.
31 There is a Makefile option NO_INSTALL_HARDLINKS for you.
33 * The smart-http backend used to always override GIT_COMMITTER_*
34 variables with REMOTE_USER and REMOTE_ADDR, but these variables are
35 now preserved when set.
37 * "git am" learned the "--include" option, which is an opposite of
38 existing the "--exclude" option.
40 * When "git am -3" needs to fall back to an application to a
41 synthesized preimage followed by a 3-way merge, the paths that
42 needed such treatment are now reported to the end user, so that the
43 result in them can be eyeballed with extra care.
45 * The output from "diff/log --stat" used to always allocate 4 columns
46 to show the number of modified lines, but not anymore.
48 * "git difftool" learned the "--dir-diff" option to spawn external
49 diff tools that can compare two directory hierarchies at a time
50 after populating two temporary directories, instead of running an
51 instance of the external tool once per a file pair.
53 * The "fmt-merge-msg" command learns to list the primary contributors
54 involved in the side topic you are merging.
56 * The cases "git push" fails due to non-ff can be broken into three
57 categories; each case is given a separate advise message.
59 * "git rebase" learned to optionally keep commits that do not
60 introduce any change in the original history.
62 * "git push --recurse-submodules" learned to optionally look into the
63 histories of submodules bound to the superproject and push them
64 out.
66 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
67 based on the commit date.
69 * "gitweb" learned to highlight the patch it outputs even more.
71 Foreign Interface
73 * "git svn" used to die with unwanted SIGPIPE when talking with HTTP
74 server that uses keep-alive.
76 * "git svn" learned to use platform specific authentication
77 providers, e.g. gnome-keyring, kwallet, etc.
79 * "git p4" has been moved out of contrib/ area and has seen more work
80 on importing labels as tags from (and exporting tags as labels to)
81 p4.
83 Performance and Internal Implementation (please report possible regressions)
85 * An experimental "version 4" format of the index file has been
86 introduced to reduce on-disk footprint and I/O overhead.
88 * "git archive" learned to produce its output without reading the
89 blob object it writes out in memory in its entirety.
91 * The code to compute hash values for lines used by the internal diff
92 engine was optimized on little-endian machines, using the same
93 trick the kernel folks came up with.
95 * "git apply" had some memory leaks plugged.
97 * "git repack" used to write out unreachable objects as loose objects
98 when repacking, even if such loose objects will immediately pruned
99 due to its age.
101 * Setting up a revision traversal with many starting points was
102 inefficient as these were placed in a date-order priority queue
103 one-by-one. Now they are collected in the queue unordered first,
104 and sorted immediately before getting used.
106 * "git rev-parse --show-prefix" used to emit nothing when run at the
107 top-level of the working tree, but now it gives a blank line.
109 * Minor memory leak during unpack_trees (hence "merge" and "checkout"
110 to check out another branch) has been plugged.
112 * More lower-level commands learned to use the streaming API to read
113 from the object store without keeping everything in core.
115 * Because "sh" on the user's PATH may be utterly broken on some
116 systems, run-command API now uses SHELL_PATH, not /bin/sh, when
117 spawning an external command (not applicable to Windows port).
119 * The API to iterate over refs/ hierarchy has been tweaked to allow
120 walking only a subset of it more efficiently.
122 Also contains minor documentation updates and code clean-ups.
125 Fixes since v1.7.10
126 -------------------
128 Unless otherwise noted, all the fixes since v1.7.10 in the maintenance
129 releases are contained in this release (see release notes to them for
130 details).
132 * When checking out another commit from an already detached state, we
133 used to report all commits that are not reachable from any of the
134 refs as lossage, but some of them might be reachable from the new
135 HEAD, and there is no need to warn about them.
136 (merge 5d88639 js/checkout-detach-count later to maint).
138 * Some time ago, "git clone" lost the progress output for its
139 "checkout" phase; when run without any "--quiet" option, it should
140 give progress to the lengthy operation.
141 (merge 8f63da1 ef/maint-clone-progress-fix later to maint).
143 * "git status --porcelain" ignored "--branch" option by mistake. The
144 output for "git status --branch -z" was also incorrect and did not
145 terminate the record for the current branch name with NUL as asked.
146 (merge d4a6bf1 jk/maint-status-porcelain-z-b later to maint).
148 * "git diff --stat" used to fully count a binary file with modified
149 execution bits whose contents is unmodified, which was not quite
150 right.
152 * "log -z --pretty=tformat:..." did not terminate each record with
153 NUL. The fix is not entirely correct when the output also asks for
154 --patch and/or --stat, though.
155 (merge fafd382 jk/maint-tformat-with-z later to maint).
