The upload_pack shell variable is initialized to an empty string, so
conditional expansion with ${upload_pack+"$upload_pack"} would not
work very well. You need a colon there.
When trying to see that an object does not exist, a state errno
leaked from our "first try to open a packfile with O_NOATIME and
then if it fails retry without it" logic on a system that refuses
O_NOATIME. This confused us and caused us to die, saying that the
packfile is unreadable, when we should have just reported that the
object does not exist in that packfile to the caller.

To prepare for allowing a different "ref" backend to be plugged in
to the system, update_ref()/delete_ref() have been taught about
ref-like things like MERGE_HEAD that are per-worktree (they will
always be written to the filesystem inside $GIT_DIR).

527ec39 (generate-cmdlist: parse common group commands, 2015-05-21)
replaced generate-cmdlist.sh with a more functional Perl version,
generate-cmdlist.perl. The Perl version gleans named tags from a new
"common groups" section in command-list.txt and recognizes those
tags in "command list" section entries in place of the old 'common'
tag. This allows git-help to, not only recognize, but also group
common commands.
Although the tests require Perl, 527ec39 creates an unconditional
dependence upon Perl in the build system itself, which can not be
overridden with NO_PERL. Such a dependency may be undesirable; for
instance, the 'git-lite' package in the FreeBSD ports tree is
intended as a minimal Git installation (which may, for example, be
useful on servers needing only local clone and update capability),
which, historically, has not depended upon Perl[1].
Therefore, revive generate-cmdlist.sh and extend it to recognize
"common groups" and its named tags. Retire generate-cmdlist.perl.
When looking for the start of the trailers in the message
we are passed, we should ignore the first line of the message.
The reason is that if we are passed a patch or commit message
then the first line should be the patch title.
If we are passed only trailers we can expect that they start
with an empty line that can be ignored too.
This way we can properly process commit messages that have
only one line with something that looks like a trailer, for
example like "area of code: change we made".

We create a strbuf only to insert a single string, pass the
resulting buffer to a function (which does not modify the

When formatting a config value into a strbuf, we may end
up stringifying it into a fixed-size buffer using sprintf,
and then copying that buffer into the strbuf. We can
eliminate the middle-man (and drop some calls to sprintf!)
by writing directly to the strbuf.
The reason it was written this way in the first place is
that we need to know before writing the value whether to
insert a delimiter. Instead of delaying the write of the
value, we speculatively write the delimiter, and roll it
back in the single case that cares.

It's unusual for a function which writes to a passed-in
strbuf to call strbuf_init; that will throw away anything
already there, leaking memory. In this case, there are
exactly two callers; one relies on this initialization and
the other passes in an already-initialized buffer.
There's no leak, as the initialized buffer doesn't have
anything in it. But let's bump the strbuf_init out to the
one caller who needs it, making format_config more
idiomatic.

ps_matched: xcalloc() takes nmemb and then element size
Even though multiplication is commutative, the order of arguments
should be xcalloc(nmemb, size). ps_matched is an array of 1-byte
element whose size is the same as the number of pathspec elements.

Merge branch 'mh/fast-import-optimize-current-from' into maint
Often a fast-import stream builds a new commit on top of the
previous commit it built, and it often unconditionally emits a
"from" command to specify the first parent, which can be omitted in
such a case. This caused fast-import to forget the tree of the

inefficient. Optimize for this common case.

am --skip/--abort: merge HEAD/ORIG_HEAD tree into index
After running "git am --abort", and then running "git reset --hard",
files that were not modified would still be re-checked out.
This is because clean_index() in builtin/am.c mistakenly called the
read_tree() function, which overwrites all entries in the index,
including the stat info.
"git am --skip" did not seem to have this issue because am_skip() called
am_run(), which called refresh_cache() to update the stat info. However,
there's still a performance penalty as the lack of stat info meant that
refresh_cache() would have to scan all files for changes.
Fix this by using unpack_trees() instead to merge the tree into the
index, so that the stat info from the index is kept.

First, the current code in untracked_cache_invalidate_path() is wrong
because it can only handle paths "a" or "a/b", not "a/b/c" because
lookup_untracked() only looks for entries directly under the given
directory. In the last case, it will look for the entry "b/c" in
directory "a" instead. This means if you delete or add an entry in a
subdirectory, untracked cache may become out of date because it does not
invalidate properly. This is noticed by David Turner.
The second problem is about invalidation inside a fully untracked/excluded
directory. In this case we may have to invalidate back to root. See the
comment block for detail.

Previously, some calls lookup_untracked would pass a full path. But
lookup_untracked assumes that the portion of the path up to and
including to the untracked_cache_dir has been removed. So
lookup_untracked would be looking in the untracked_cache for 'foo' for
'foo/bar' (instead of just looking for 'bar'). This would cause
untracked cache corruption.
Instead, treat_directory learns to track the base length of the parent
directory, so that only the last path component is passed to
lookup_untracked.
