1 GIT v1.6.1 Release Notes
2 ========================
7 When some commands (e.g. "git log", "git diff") spawn pager internally, we
8 used to make the pager the parent process of the git command that produces
9 output. This meant that the exit status of the whole thing comes from the
10 pager, not the underlying git command. We swapped the order of the
11 processes around and you will see the exit code from the command from now
16 * gitk can call out to git-gui to view "git blame" output; git-gui in turn
17 can run gitk from its blame view.
19 * Various git-gui updates including updated translations.
21 * Various gitweb updates from repo.or.cz installation.
23 * Updates to emacs bindings.
27 * A few test scripts used nonportable "grep" that did not work well on
28 some platforms, e.g. Solaris.
30 * Sample pre-auto-gc script has OS X support.
32 * Makefile has support for (ancient) FreeBSD 4.9.
36 * Many operations that are lstat(3) heavy can be told to pre-execute
37 necessary lstat(3) in parallel before their main operations, which
38 potentially gives much improved performance for cold-cache cases or in
39 environments with weak metadata caching (e.g. NFS).
41 * The underlying diff machinery to produce textual output has been
42 optimized, which would result in faster "git blame" processing.
44 * Most of the test scripts (but not the ones that try to run servers)
45 can be run in parallel.
47 * Bash completion of refnames in a repository with massive number of
48 refs has been optimized.
50 * Cygwin port uses native stat/lstat implementations when applicable,
51 which leads to improved performance.
53 * "git push" pays attention to alternate repositories to avoid sending
56 * "git svn" can rebuild an out-of-date rev_map file.
58 (usability, bells and whistles)
60 * When you mistype a command name, git helpfully suggests what it guesses
61 you might have meant to say. help.autocorrect configuration can be set
62 to a non-zero value to accept the suggestion when git can uniquely
65 * The packfile machinery hopefully is more robust when dealing with
66 corrupt packs if redundant objects involved in the corruption are
69 * "git add -N path..." adds the named paths as an empty blob, so that
70 subsequent "git diff" will show a diff as if they are creation events.
72 * "git apply" learned --include=paths option, similar to the existing
73 --exclude=paths option.
75 * "git bisect" is careful about a user mistake and suggests testing of
76 merge base first when good is not a strict ancestor of bad.
78 * "git blame" re-encodes the commit metainfo to UTF-8 from i18n.commitEncoding
81 * "git check-attr --stdin" can check attributes for multiple paths.
83 * "git checkout --track origin/hack" used to be a syntax error. It now
84 DWIMs to create a corresponding local branch "hack", i.e. acts as if you
85 said "git checkout --track -b hack origin/hack".
87 * "git checkout --ours/--theirs" can be used to check out one side of a
88 conflicting merge during conflict resolution.
90 * "git checkout -m" can be used to recreate the initial conflicted state
91 during conflict resolution.
93 * "git cherry-pick" can also utilize rerere for conflict resolution.
95 * "git clone" learned to be verbose with -v
97 * "git commit --author=$name" can look up author name from existing
100 * output from "git commit" has been reworded in a more concise and yet
101 more informative way.
103 * "git count-objects" reports the on-disk footprint for packfiles and
104 their corresponding idx files.
106 * "git daemon" learned --max-connections=<count> option.
108 * "git daemon" exports REMOTE_ADDR to record client address, so that
109 spawned programs can act differently on it.
111 * "git describe --tags" favours closer lightweight tags than farther
114 * "git diff" learned to mimic --suppress-blank-empty from GNU diff via a
115 configuration option.
117 * "git diff" learned to put more sensible hunk headers for Python,
118 HTML and ObjC contents.
120 * "git diff" learned to vary the a/ vs b/ prefix depending on what are
121 being compared, controlled by diff.mnemonicprefix configuration.
123 * "git diff" learned --dirstat-by-file to count changed files, not number
124 of lines, when summarizing the global picture.
126 * "git diff" learned "textconv" filters --- a binary or hard-to-read
127 contents can be munged into human readable form and the difference
128 between the results of the conversion can be viewed (obviously this
129 cannot produce a patch that can be applied, so this is disabled in
130 format-patch among other things).
132 * "git diff" hunk header pattern for ObjC has been added.
134 * "--cached" option to "git diff has an easier to remember synonym "--staged",
135 to ask "what is the difference between the given commit and the
136 contents staged in the index?"
138 * a "textconv" filter that makes binary files textual form for human
139 consumption can be specified as an attribute for paths; "git diff"
140 learnt to make use of it.
142 * "git for-each-ref" learned "refname:short" token that gives an
143 unambiguously abbreviated refname.
145 * Auto-numbering of the subject lines is the default for "git
148 * "git grep" learned to accept -z similar to GNU grep.
150 * "git help" learned to use GIT_MAN_VIEWER environment variable before
153 * "git imap-send" can optionally talk SSL.
155 * "git index-pack" is more careful against disk corruption while
156 completing a thin pack.
158 * "git log --check" and "git log --exit-code" passes their underlying diff
159 status with their exit status code.
161 * "git log" learned --simplify-merges, a milder variant of --full-history;
162 "gitk --simplify-merges" is easier to view than with --full-history.
164 * "git log" learned "--source" to show what ref each commit was reached
167 * "git log" also learned "--simplify-by-decoration" to show the
168 birds-eye-view of the topology of the history.
170 * "git log --pretty=format:" learned "%d" format element that inserts
171 names of tags that point at the commit.
173 * "git merge --squash" and "git merge --no-ff" into an unborn branch are
174 noticed as user errors.
176 * "git merge -s $strategy" can use a custom built strategy if you have a
177 command "git-merge-$strategy" on your $PATH.
179 * "git pull" (and "git fetch") can be told to operate "-v"erbosely or
182 * "git push" can be told to reject deletion of refs with receive.denyDeletes
185 * "git rebase" honours pre-rebase hook; use --no-verify to bypass it.
187 * "git rebase -p" uses interactive rebase machinery now to preserve the merges.
189 * "git reflog expire branch" can be used in place of "git reflog expire
192 * "git remote show $remote" lists remote branches one-per-line now.
194 * when giving up resolving a conflicted merge, "git reset --hard" failed
195 to remove new paths from the working tree. [cherry-pick to 'maint'?]
197 * "git send-email" can be given revision range instead of files and
198 maildirs on the command line, and automatically runs format-patch to
199 generate patches for the given revision range.
201 * "git submodule foreach" subcommand allows you to iterate over checked
204 * "git submodule sync" subcommands allows you to update the origin URL
205 recorded in submodule directories from the toplevel .gitmodules file.
207 * "git svn branch" can create new branches on the other end.
209 * "gitweb" can use more saner PATH_INFO based URL.
213 * "git hash-object" learned to lie about the path being hashed, so that
214 correct gitattributes processing can be done while hashing contents
215 stored in a temporary file.
217 * various callers of git-merge-recursive avoid forking it as an external
220 * Git class defined in "Git.pm" can be subclasses a bit more easily.
222 * We used to link GNU regex library as a compatibility layer for some
223 platforms, but it turns out it is not necessary on most of them.
225 * Some path handling routines used fixed number of buffers used alternately
226 but depending on the call depth, this arrangement led to hard to track
227 bugs. This issue is being addressed.
233 All of the fixes in v1.6.0.X maintenance series are included in this
234 release, unless otherwise noted.
236 * "git add" and "git update-index" incorrectly allowed adding S/F when S
237 is a tracked symlink that points at a directory D that has a path F in
238 it (we still need to fix a similar nonsense when S is a submodule and F
241 * "git diff --stdin" used to take two trees on a line and compared them,
242 but we dropped support for such a use case long time ago. This has
245 * Giving 3 or more tree-ish to "git diff" is supposed to show the combined
246 diff from second and subsequent trees to the first one. b75271d ("git
247 diff <tree>{3,}": do not reverse order of arguments, 2008-10-10) needs
248 to be cherry-picked to 'maint'.
250 * "git filter-branch" failed to rewrite a tag name with slashes in it.
252 * "git repack" used to grab objects out of packs marked with .keep
253 into a new pack (fix scheduled to be further downmerged to maint).
255 * "git push --tags --all $there" failed with generic usage message without
256 telling saying these two options are incompatible.
258 * "git log --author/--committer" match used to potentially match the
259 timestamp part, exposing internal implementation detail. Also these did
260 not work with --fixed-strings match at all.
262 * Internal diff machinery had a corner case performance bug that choked on a
263 large file with many repeated contents (fix scheduled to be further cherry-
