Git v2.9.3 Release Notes
========================

Fixes since v2.9.2
------------------

 * A helper function that takes the contents of a commit object and
   finds its subject line did not ignore leading blank lines, as is
   commonly done by other codepaths.  Make it ignore leading blank
   lines to match.

 * Git does not know what the contents in the index should be for a
   path added with "git add -N" yet, so "git grep --cached" should not
   show hits (or show lack of hits, with -L) in such a path, but that
   logic does not apply to "git grep", i.e. searching in the working
   tree files.  But we did so by mistake, which has been corrected.

 * "git rebase -i --autostash" did not restore the auto-stashed change
   when the operation was aborted.

 * "git commit --amend --allow-empty-message -S" for a commit without
   any message body could have misidentified where the header of the
   commit object ends.

 * More mark-up updates to typeset strings that are expected to
   literally typed by the end user in fixed-width font.

 * For a long time, we carried an in-code comment that said our
   colored output would work only when we use fprintf/fputs on
   Windows, which no longer is the case for the past few years.

 * "gc.autoPackLimit" when set to 1 should not trigger a repacking
   when there is only one pack, but the code counted poorly and did
   so.

 * One part of "git am" had an oddball helper function that called
   stuff from outside "his" as opposed to calling what we have "ours",
   which was not gender-neutral and also inconsistent with the rest of
   the system where outside stuff is usuall called "theirs" in
   contrast to "ours".

 * The test framework learned a new helper test_match_signal to
   check an exit code from getting killed by an expected signal.

 * "git blame -M" missed a single line that was moved within the file.

 * Fix recently introduced codepaths that are involved in parallel
   submodule operations, which gave up on reading too early, and
   could have wasted CPU while attempting to write under a corner
   case condition.

 * "git grep -i" has been taught to fold case in non-ascii locales
   correctly.

 * A test that unconditionally used "mktemp" learned that the command
   is not necessarily available everywhere.

 * "git blame file" allowed the lineage of lines in the uncommitted,
   unadded contents of "file" to be inspected, but it refused when
   "file" did not appear in the current commit.  When "file" was
   created by renaming an existing file (but the change has not been
   committed), this restriction was unnecessarily tight.

 * "git add -N dir/file && git write-tree" produced an incorrect tree
   when there are other paths in the same directory that sorts after
   "file".

 * "git fetch http://user:pass@host/repo..." scrubbed the userinfo
   part, but "git push" didn't.

 * An age old bug that caused "git diff --ignore-space-at-eol"
   misbehave has been fixed.

 * "git notes merge" had a code to see if a path exists (and fails if
   it does) and then open the path for writing (when it doesn't).
   Replace it with open with O_EXCL.

 * "git pack-objects" and "git index-pack" mostly operate with off_t
   when talking about the offset of objects in a packfile, but there
   were a handful of places that used "unsigned long" to hold that
   value, leading to an unintended truncation.

 * Recent update to "git daemon" tries to enable the socket-level
   KEEPALIVE, but when it is spawned via inetd, the standard input
   file descriptor may not necessarily be connected to a socket.
   Suppress an ENOTSOCK error from setsockopt().

 * Recent FreeBSD stopped making perl available at /usr/bin/perl;
   switch the default the built-in path to /usr/local/bin/perl on not
   too ancient FreeBSD releases.

Also contains minor documentation updates and code clean-ups.
