git reflog (ab)uses the log machinery to display its list of log
entries. To do so it must fake commit parent information for the log
walker.
For refs in refs/heads this is no problem, as they should only ever
point to commits. Tags and other refs however can point to anything,
thus their reflog may contain non-commit objects.
To avoid segfaulting, we check whether reflog entries are commits before
feeding them to the log walker and skip any non-commits. This means that
git reflog output will be incomplete for such refs, but that's one step
up from segfaulting. A more complete solution would be to decouple git
reflog from the log walker machinery.

The helper used to iterate over loose object directories to prune
stale objects did not closedir() immediately when it is done with a
directory--a callback such as the one used for "git prune" may want
to do rmdir(), but it would fail on open directory on platforms
such as WinXP.

into the helper function "canonical_name". But when moving
the code, it forgot that the "buf" variable is passed as
"host" in the helper.

mark_tree_uninteresting() has code to handle the case where it gets
passed a NULL pointer in its 'tree' parameter, but the function had
'object = &tree->object' assignment before checking if tree is
NULL. This gives a compiler an excuse to declare that tree will
never be NULL and apply a wrong optimization. Avoid it.

The git-submodule(1) is inconsistent. In the synopsis, it says:
git submodule [--quiet] sync [--recursive] [--] [<path>...]
The description of the sync does not mention --recursive, and the
description of --recursive says that it is only available for foreach,
update and status.
The option was introduced (82f49f294c, Teach --recursive to submodule
sync, 2012-10-26) a while ago, so let's document it, too.

The code to prepare the working tree side of temporary directory
for the "dir-diff" feature forgot that symbolic links need not be
copied (or symlinked) to the temporary area, as the code already
special cases and overwrites them. Besides, it was wrong to try
computing the object name of the target of symbolic link, which may
not even exist or may be a directory.

Having a leftover .idx file without corresponding .pack file in
the repository hurts performance; "git gc" learned to prune them.

topic.

In verify_pack, a caller-supplied verification function is called.
The function returns an int. If that return value is non-zero,
verify_pack should fail.
The only caller of verify_pack is in builtin/fsck.c, whose verify_fn
returns a meaningful error code (which was then ignored). Now, fsck
might return a different error code (with more detail). This would
happen in the unlikely event that a commit or tree that is a valid git
object but not a valid instance of its type gets into a pack.

The error message after a failing commit_lock_file() call sometimes
looks like this, causing confusion:
$ git remote add remote git@server.com/repo.git
error: could not commit config file .git/config
# Huh?!
# I didn't want to commit anything, especially not my config file!
While in the narrow context of the lockfile module using the verb
'commit' in the error message makes perfect sense, in the broader
context of git the word 'commit' already has a very specific meaning,
hence the confusion.
Reword these error messages to say "could not write" instead of "could
not commit".
While at it, include strerror in the error messages after writing the
config file or the credential store fails to provide some information
about the cause of the failure, and update the style of the error
message after writing the reflog fails to match surrounding error
messages (i.e. no '' around the pathname and no () around the error
description).

And if a branch is named "H", "HE", or "HEA" then the current if clause
erroneously considers it as matching "HEAD" because it only compares
up to the end of the branch name.
Fix that by doing the comparison using strcmp() and only after the
branch name is extracted. This way neither too less nor too many
characters are checked. While at it call strchrnul() to find the end
of the branch name instead of open-coding it.
