Git v2.10.1 Release Notes

Fixes since v2.10

* Clarify various ways to specify the "revision ranges" in the

* "diff-highlight" script (in contrib/) learned to work better with
"git log -p --graph" output.

* The test framework left the number of tests and success/failure
count in the t/test-results directory, keyed by the name of the
test script plus the process ID. The latter however turned out not
to serve any useful purpose. The process ID part of the filename
has been removed.

* Having a submodule whose ".git" repository is somehow corrupt
caused a few commands that recurse into submodules loop forever.

* "git symbolic-ref -d HEAD" happily removes the symbolic ref, but
the resulting repository becomes an invalid one. Teach the command
to forbid removal of HEAD.

* A test spawned a short-lived background process, which sometimes
prevented the test directory from getting removed at the end of the
script on some platforms.

* Update a few tests that used to use GIT_CURL_VERBOSE to use the

* Update Japanese translation for "git-gui".

* "git fetch http::/site/path" did not die correctly and segfaulted

* "git commit-tree" stopped reading commit.gpgsign configuration
variable that was meant for Porcelain "git commit" in Git 2.9; we
forgot to update "git gui" to look at the configuration to match
this change.

* "git log --cherry-pick" used to include merge commits as candidates
to be matched up with other commits, resulting a lot of wasted time.
The patch-id generation logic has been updated to ignore merges to
avoid the wastage.

* The http transport (with curl-multi option, which is the default
these days) failed to remove curl-easy handle from a curlm session,
which led to unnecessary API failures.

* "git diff -W" output needs to extend the context backward to
include the header line of the current function and also forward to
include the body of the entire current function up to the header
line of the next one. This process may have to merge to adjacent
hunks, but the code forgot to do so in some cases.

* Performance tests done via "t/perf" did not use the same set of
build configuration if the user relied on autoconf generated

* "git format-patch --base=..." feature that was recently added
showed the base commit information after "-- " e-mail signature
line, which turned out to be inconvenient. The base information
has been moved above the signature line.

* Even when "git pull --rebase=preserve" (and the underlying "git
rebase --preserve") can complete without creating any new commit
(i.e. fast-forwards), it still insisted on having a usable ident
information (read: is set correctly), which was less
than nice. As the underlying commands used inside "git rebase"
would fail with a more meaningful error message and advice text
when the bogus ident matters, this extra check was removed.

* "git gc --aggressive" used to limit the delta-chain length to 250,
which is way too deep for gaining additional space savings and is
detrimental for runtime performance. The limit has been reduced to

* Documentation for individual configuration variables to control use
of color (like `color.grep`) said that their default value is
'false', instead of saying their default is taken from `color.ui`.
When we updated the default value for color.ui from 'false' to
'auto' quite a while ago, all of them broke. This has been

* A shell script example in check-ref-format documentation has been

* "git checkout <word>" does not follow the usual disambiguation
rules when the <word> can be both a rev and a path, to allow
checking out a branch 'foo' in a project that happens to have a
file 'foo' in the working tree without having to disambiguate.
This was poorly documented and the check was incorrect when the
command was run from a subdirectory.

* Some codepaths in "git diff" used regexec(3) on a buffer that was
mmap(2)ed, which may not have a terminating NUL, leading to a read
beyond the end of the mapped region. This was fixed by introducing
a regexec_buf() helper that takes a <ptr,len> pair with REG_STARTEND

* The procedure to build Git on Mac OS X for Travis CI hardcoded the
internal directory structure we assumed HomeBrew uses, which was a
no-no. The procedure has been updated to ask HomeBrew things we
need to know to fix this.

* When "git rebase -i" is given a broken instruction, it told the
user to fix it with "--edit-todo", but didn't say what the step
after that was (i.e. "--continue").

* "git add --chmod=+x" added recently lacked documentation, which has
been corrected.

* "git add --chmod=+x <pathspec>" added recently only toggled the
executable bit for paths that are either new or modified. This has
been corrected to flip the executable bit for all paths that match
the given pathspec.

* "git pack-objects --include-tag" was taught that when we know that
we are sending an object C, we want a tag B that directly points at
C but also a tag A that points at the tag B. We used to miss the
intermediate tag B in some cases.

* Documentation around tools to import from CVS was fairly outdated.

* In the codepath that comes up with the hostname to be used in an
e-mail when the user didn't tell us, we looked at ai_canonname
field in struct addrinfo without making sure it is not NULL first.

Also contains minor documentation updates and code clean-ups.
