1 Git v1.8.1 Release Notes
2 ========================
4 Backward compatibility notes
5 ----------------------------
7 In the next major release (not *this* one), we will change the
8 behavior of the "git push" command.
10 When "git push [$there]" does not say what to push, we have used the
11 traditional "matching" semantics so far (all your branches were sent
12 to the remote as long as there already are branches of the same name
13 over there). We will use the "simple" semantics that pushes the
14 current branch to the branch with the same name, only when the current
15 branch is set to integrate with that remote branch. There is a user
16 preference configuration variable "push.default" to change this, and
17 "git push" will warn about the upcoming change until you set this
18 variable in this release.
20 "git branch --set-upstream" is deprecated and may be removed in a
21 relatively distant future. "git branch [-u|--set-upstream-to]" has
22 been introduced with a saner order of arguments.
25 Updates since v1.8.0
26 --------------------
28 UI, Workflows & Features
30 * We used to have a workaround for a bug in ancient "less" that
31 causes it to exit without any output when the terminal is resized.
32 The bug has been fixed in "less" version 406 (June 2007), and the
33 workaround has been removed in this release.
35 * A new configuration variable "diff.context" can be used to
36 give the default number of context lines in the patch output, to
37 override the hardcoded default of 3 lines.
39 * "git format-patch" leraned the "--notes=<ref>" option to give
40 notes for the commit after the three-dash lines in its output.
42 * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
43 configuration set to "perl".
45 * "git rm $submodule" used to punt on removing a submodule working
46 tree to avoid losing the repository embedded in it. Because
47 recent git uses a mechanism to separate the submodule repository
48 from the submodule working tree, "git rm" learned to detect this
49 case and removes the submodule working tree when it is safe.
51 * "git submodule add" learned to add a new submodule at the same
52 path as the path where an unrelated submodule was bound to in an
53 existing revision via the "--name" option.
55 * "git submodule sync" learned the "--recursive" option.
57 * "git symbolic-ref" learned the "-d $symref" option to delete the
58 named symbolic ref, which is more intuitive way to spell it than
59 "update-ref -d --no-deref".
62 Foreign Interface
64 * "git cvsimport" can be told to record timezones (other than GMT)
65 per-author via its author info file.
67 * The remote helper interface to interact with subversion
68 repositories (one of the GSoC 2012 projects) has been merged.
71 Performance, Internal Implementation, etc.
73 * The logic to generate the initial advertisement from
74 "upload-pack" (what is invoked by "git fetch" on the other side
75 of the connection) to list what refs are available in the
76 repository has been optimized.
78 * The logic to find set of attributes that match a given path has
79 been optimized.
82 Also contains minor documentation updates and code clean-ups.
85 Fixes since v1.8.0
86 ------------------
88 Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
89 track are contained in this release (see release notes to them for
90 details).
92 * The configuration parser had an unnecessary hardcoded limit on
93 variable names that was not checked consistently.
94 (merge 0971e99 bw/config-lift-variable-name-length-limit later to maint).
96 * The "say" function in the test scaffolding incorrectly allowed
97 "echo" to interpret "\a" as if it were a C-string asking for a
98 BEL output.
99 (merge 7bc0911 jc/test-say-color-avoid-echo-escape later to maint).
101 * "git mergetool" feeds /dev/null as a common ancestor when dealing
102 with an add/add conflict, but p4merge backend cannot handle
103 it. Work it around by passing a temporary empty file.
104 (merge 3facc60 da/mergetools-p4 later to maint).
106 * "git log -F -E --grep='<ere>'" failed to use the given <ere>
107 pattern as extended regular expression, and instead looked for the
108 string literally.
109 (merge 727b6fc jc/grep-pcre-loose-ends~1 later to maint).
111 * "git grep -e pattern <tree>" asked the attribute system to read
112 "<tree>:.gitattributes" file in the working tree, which was
113 nonsense.
114 (merge 55c6168 nd/grep-true-path later to maint).
116 * A symbolic ref refs/heads/SYM was not correctly removed with "git
117 branch -d SYM"; the command removed the ref pointed by SYM
118 instead.
119 (merge 13baa9f rs/branch-del-symref later to maint).
121 * Update "remote tracking branch" in the documentation to
122 "remote-tracking branch".
123 (merge a6d3bde mm/maint-doc-remote-tracking later to maint).
125 * "git pull --rebase" run while the HEAD is detached tried to find
126 the upstream branch of the detached HEAD (which by definition
127 does not exist) and emitted unnecessary error messages.
128 (merge e980765 ph/pull-rebase-detached later to maint).
130 * The refs/replace hierarchy was not mentioned in the
131 repository-layout docs.
132 (merge 11fbe18 po/maint-refs-replace-docs later to maint).
134 * Various rfc2047 quoting issues around a non-ASCII name on the
135 From: line in the output from format-patch has been corrected.
136 (merge 25dc8da js/format-2047 later to maint).
138 * Sometimes curl_multi_timeout() function suggested a wrong timeout
139 value when there is no file descriptors to wait on and the http
140 transport ended up sleeping for minutes in select(2) system call.
141 A workaround has been added for this.
142 (merge 7202b81 sz/maint-curl-multi-timeout later to maint).
144 * For a fetch refspec (or the result of applying wildcard on one),
145 we always want the RHS to map to something inside "refs/"
146 hierarchy, but the logic to check it was not exactly right.
147 (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
149 * "git diff -G<pattern>" did not honor textconv filter when looking
150 for changes.
151 (merge b1c2f57 jk/maint-diff-grep-textconv later to maint).
