"git subtree" (in contrib/) records the tag object name in the

the command forgot to do so.

"git grep" by default does not fall back to its "--no-index"
behaviour outside a directory under Git's control (otherwise the

disabled.

Asking gitweb for a nonexistent commit left a warning in the server

Some codepaths used fopen(3) when opening a fixed path in $GIT_DIR
(e.g. COMMIT_EDITMSG) that is meant to be left after the command is
done. This however did not work well if the repository is set to
be shared with core.sharedRepository and the umask of the previous
user is tighter. They have been made to work better by calling
unlink(2) and retrying after fopen(3) fails with EPERM.

Documentation for "git fetch --depth" has been updated for clarity.

The ignore mechanism saw a few regressions around untracked file
listing and sparse checkout selection areas in 2.7.0; the change
that is responsible for the regression has been reverted.
* nd/exclusion-regression-fix:

d95138e6 (setup: set env $GIT_WORK_TREE when work tree is set, like
$GIT_DIR, 2015-06-26) attempted to work around a glitch in alias

Some "git notes" operations, e.g. "git log --notes=<note>", should
be able to read notes from any tree-ish that is shaped like a notes
tree, but the notes infrastructure required that the argument must
be a ref under refs/notes/. Loosen it to require a valid ref only
when the operation would update the notes (in which case we must
have a place to store the updated notes tree, iow, a ref).
* mh/notes-allow-reading-treeish:
notes: allow treeish expressions as notes ref
Commit 348d4f2 (filter-branch: skip index read/write when
possible, 2015-11-06) taught filter-branch to optimize out
the final "git write-tree" when we know we haven't touched
the tree with any of our filters. It does by simply putting
the literal text "$commit^{tree}" into the "$tree" variable,
avoiding a useless rev-parse call.
However, when we pass this to git_commit_non_empty_tree(),
it gets confused; it resolves "$commit^{tree}" itself, and
compares our string to the 40-hex sha1, which obviously
doesn't match. As a result, "--prune-empty" (or any custom
filter using git_commit_non_empty_tree) will fail to drop
an empty commit (when filter-branch is used without a tree
or index filter).
Let's resolve $tree to the 40-hex ourselves, so that
git_commit_non_empty_tree can work. Unfortunately, this is a
bit slower due to the extra process overhead:
$ cd t/perf && ./run 348d4f2 HEAD p7000-filter-branch.sh
[...]
Test 348d4f2 HEAD
--------------------------------------------------------------
7000.2: noop filter 3.76(0.24+0.26) 4.54(0.28+0.24) +20.7%
We could try to make git_commit_non_empty_tree more clever.
However, the value of $tree here is technically
user-visible. The user can provide arbitrary shell code at
this stage, which could itself have a similar assumption to
what is in git_commit_non_empty_tree. So the conservative
choice to fix this regression is to take the 20% hit and
give the pre-348d4f2 behavior. We still end up much faster
than before the optimization:
$ cd t/perf && ./run 348d4f2^ HEAD p7000-filter-branch.sh
[...]
Test 348d4f2^ HEAD
--------------------------------------------------------------
7000.2: noop filter 9.51(4.32+0.40) 4.51(0.28+0.23) -52.6%

its log message and the actual tests.

MSys2's compiler is correct that casting a "void *" to a "DWORD" loses
precision, but in the case of pthread_exit() we know that the value
fits into a DWORD.
Just like casting handles to DWORDs, let's work around this issue by
casting to "intrptr_t" first, and immediately cast to the final type.

HANDLE is defined internally as a void *, but in many cases it is

not warn about a cast of a pointer to an integer of a different type
because we know exactly what we are doing.

The config variable branch.<branchname>.rebase is not only used by `git

A couple of years ago, I found the need to collaborate on topic
branches that were rebased all the time, and I really needed to see
what I was rebasing when pulling, so I introduced an
interactively-rebasing pull.
The way builtin pull works, this change also supports the value
'interactive' for the 'branch.<name>.rebase' config variable, which
is a neat thing because users can now configure given branches for
interactively-rebasing pulls without having to type out the complete
`--rebase=interactive` option every time they pull.

After rebasing, we call "gc --auto" to clean up if we
created a lot of loose objects. However, we do so inside an
&&-chain. If "gc --auto" fails (e.g., because a previous
background gc blocked us by leaving "gc.log" in place),
then:
1. We will fail to clean up the state directory, leaving
the user stuck in the rebase forever (even "git am
--abort" doesn't work, because it calls "gc --auto"!).
2. In some cases, we may return a bogus exit code from
rebase, indicating failure when everything except the
auto-gc succeeded.
We can fix this by ignoring the exit code of "gc --auto".
