Git v1.7.7.1 Release Notes

==========================

Fixes since v1.7.7

------------------

* "git diff $tree $path" used to apply the pathspec at the output stage,

reading the whole tree, wasting resources.

* The code to check for updated submodules during a "git fetch" of the

superproject had an unnecessary quadratic loop.

* "git fetch" from a large bundle did not enable the progress output.

* When "git fsck --lost-and-found" found that an empty blob object in the

object store is unreachable, it incorrectly reported an error after

writing the lost blob out successfully.

* "git filter-branch" did not refresh the index before checking that the

working tree was clean.

* "git grep $tree" when run with multiple threads had an unsafe access to

the object database that should have been protected with mutex.

* The "--ancestry-path" option to "git log" and friends misbehaved in a

history with complex criss-cross merges and showed an uninteresting

side history as well.

* Test t1304 assumed LOGNAME is always set, which may not be true on

some systems.

* Tests with --valgrind failed to find "mergetool" scriptlets.

* "git patch-id" miscomputed the patch-id in a patch that has a line longer

than 1kB.

* When an "exec" insn failed after modifying the index and/or the working

tree during "rebase -i", we now check and warn that the changes need to

be cleaned up.
