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 * Command-line completion for tcsh has been added.
32 * We used to have a workaround for a bug in ancient "less" that
33 causes it to exit without any output when the terminal is resized.
34 The bug has been fixed in "less" version 406 (June 2007), and the
35 workaround has been removed in this release.
37 * Some documentation pages that used to ship only in the plain text
38 format are now formatted in HTML as well.
40 * "git-prompt" scriptlet (in contrib/completion) can be told to paint
41 pieces of the hints in the prompt string in colors.
43 * A new configuration variable "diff.context" can be used to
44 give the default number of context lines in the patch output, to
45 override the hardcoded default of 3 lines.
47 * "git config --get" used to diagnose presence of multiple
48 definitions of the same variable in the same configuration file as
49 an error, but it now applies the "last one wins" rule used by the
50 internal configuration logic. Strictly speaking, this may be an
51 API regression but it is expected that nobody will notice it in
52 practice.
54 * "git format-patch" learned the "--notes=<ref>" option to give
55 notes for the commit after the three-dash lines in its output.
57 * "git log --grep=<pcre>" learned to honor the "grep.patterntype"
58 configuration set to "perl".
60 * "git replace -d <object>" now interprets <object>, instead of only
61 accepting full hex object name.
63 * "git rm $submodule" used to punt on removing a submodule working
64 tree to avoid losing the repository embedded in it. Because
65 recent git uses a mechanism to separate the submodule repository
66 from the submodule working tree, "git rm" learned to detect this
67 case and removes the submodule working tree when it is safe.
69 * "git submodule add" learned to add a new submodule at the same
70 path as the path where an unrelated submodule was bound to in an
71 existing revision via the "--name" option.
73 * "git submodule sync" learned the "--recursive" option.
75 * "diff.submodule" configuration variable can be used to give custom
76 default value to the "git diff --submodule" option.
78 * "git symbolic-ref" learned the "-d $symref" option to delete the
79 named symbolic ref, which is more intuitive way to spell it than
80 "update-ref -d --no-deref".
83 Foreign Interface
85 * "git cvsimport" can be told to record timezones (other than GMT)
86 per-author via its author info file.
88 * The remote helper interface to interact with subversion
89 repositories (one of the GSoC 2012 projects) has been merged.
92 Performance, Internal Implementation, etc.
94 * Compilation on Cygwin with newer header files are supported now.
96 * The logic to generate the initial advertisement from
97 "upload-pack" (what is invoked by "git fetch" on the other side
98 of the connection) to list what refs are available in the
99 repository has been optimized.
101 * The logic to find set of attributes that match a given path has
102 been optimized.
104 * Use preloadindex in "git diff-index" and "git update-index", which
105 has a nice speedup on systems with slow stat calls (and even on
106 Linux).
109 Also contains minor documentation updates and code clean-ups.
112 Fixes since v1.8.0
113 ------------------
115 Unless otherwise noted, all the fixes since v1.8.0 in the maintenance
116 track are contained in this release (see release notes to them for
117 details).
119 * The configuration parser had an unnecessary hardcoded limit on
120 variable names that was not checked consistently.
121 (merge 0971e99 bw/config-lift-variable-name-length-limit later to maint).
123 * The "say" function in the test scaffolding incorrectly allowed
124 "echo" to interpret "\a" as if it were a C-string asking for a
125 BEL output.
126 (merge 7bc0911 jc/test-say-color-avoid-echo-escape later to maint).
128 * "git mergetool" feeds /dev/null as a common ancestor when dealing
129 with an add/add conflict, but p4merge backend cannot handle
130 it. Work it around by passing a temporary empty file.
131 (merge 3facc60 da/mergetools-p4 later to maint).
133 * "git log -F -E --grep='<ere>'" failed to use the given <ere>
134 pattern as extended regular expression, and instead looked for the
135 string literally.
136 (merge 727b6fc jc/grep-pcre-loose-ends~1 later to maint).
138 * "git grep -e pattern <tree>" asked the attribute system to read
139 "<tree>:.gitattributes" file in the working tree, which was
140 nonsense.
141 (merge 55c6168 nd/grep-true-path later to maint).
143 * A symbolic ref refs/heads/SYM was not correctly removed with "git
144 branch -d SYM"; the command removed the ref pointed by SYM
145 instead.
146 (merge 13baa9f rs/branch-del-symref later to maint).
148 * Update "remote tracking branch" in the documentation to
149 "remote-tracking branch".
150 (merge a6d3bde mm/maint-doc-remote-tracking later to maint).
152 * "git pull --rebase" run while the HEAD is detached tried to find
153 the upstream branch of the detached HEAD (which by definition
154 does not exist) and emitted unnecessary error messages.
155 (merge e980765 ph/pull-rebase-detached later to maint).
157 * The refs/replace hierarchy was not mentioned in the
158 repository-layout docs.
159 (merge 11fbe18 po/maint-refs-replace-docs later to maint).
161 * Various rfc2047 quoting issues around a non-ASCII name on the
162 From: line in the output from format-patch have been corrected.
163 (merge 25dc8da js/format-2047 later to maint).
165 * Sometimes curl_multi_timeout() function suggested a wrong timeout
166 value when there is no file descriptor to wait on and the http
167 transport ended up sleeping for minutes in select(2) system call.
168 A workaround has been added for this.
169 (merge 7202b81 sz/maint-curl-multi-timeout later to maint).
171 * For a fetch refspec (or the result of applying wildcard on one),
172 we always want the RHS to map to something inside "refs/"
173 hierarchy, but the logic to check it was not exactly right.
174 (merge 5c08c1f jc/maint-fetch-tighten-refname-check later to maint).
176 * "git diff -G<pattern>" did not honor textconv filter when looking
177 for changes.
178 (merge b1c2f57 jk/maint-diff-grep-textconv later to maint).
180 * Some HTTP servers ask for auth only during the actual packing phase
181 (not in ls-remote phase); this is not really a recommended
182 configuration, but the clients used to fail to authenticate with
183 such servers.
184 (merge 2e736fd jk/maint-http-half-auth-fetch later to maint).
186 * "git p4" used to try expanding malformed "$keyword$" that spans
187 across multiple lines.
188 (merge 6b2bf41 pw/maint-p4-rcs-expansion-newline later to maint).
190 * Syntax highlighting in "gitweb" was not quite working.
191 (merge 048b399 rh/maint-gitweb-highlight-ext later to maint).
193 * RSS feed from "gitweb" had a xss hole in its title output.
194 (merge 0f0ecf6 jk/maint-gitweb-xss later to maint).
196 * "git config --path $key" segfaulted on "[section] key" (a boolean
197 "true" spelled without "=", not "[section] key = true").
198 (merge 962c38e cn/config-missing-path later to maint).
200 * "git checkout -b foo" while on an unborn branch did not say
201 "Switched to a new branch 'foo'" like other cases.
202 (merge afa8c07 jk/checkout-out-of-unborn later to maint).
204 * We failed to mention a file without any content change but whose
205 permission bit was modified, or (worse yet) a new file without any
206 content in the "git diff --stat" output.
207 (merge 74faaa1 lt/diff-stat-show-0-lines later to maint).
209 * "update-ref -d --deref SYM" to delete a ref through a symbolic ref
210 that points to it did not remove it correctly.
211 (merge b274a71 jh/update-ref-d-through-symref later to maint).
