b72a1904ae revision: avoid work after --max-count is reached
During a revision traversal in which --max-count has been
specified, we decrement a counter for each revision returned
by get_revision. When it hits 0, we typically return NULL
(the exception being if we still have boundary commits to
show).

However, before we check the counter, we call get_revision_1
to get the next commit. This might involve looking at a
large number of commits if we have restricted the traversal
(e.g., we might traverse until we find the next commit whose
diff actually matches a pathspec).

There's no need to make this get_revision_1 call when our
counter runs out. If we are not in --boundary mode, we will
just throw away the result and immediately return NULL. If
we are in --boundary mode, then we will still throw away the
result, and then start showing the boundary commits.
However, as git_revision_1 does not impact the boundary
list, it should not have an impact.

In most cases, avoiding this work will not be especially
noticeable. However, in some cases, it can make a big
difference:

  [before]
  $ time git rev-list -1 origin Documentation/RelNotes/1.7.11.2.txt
  8d141a1d56

  real    0m0.301s
  user    0m0.280s
  sys     0m0.016s

  [after]
  $ time git rev-list -1 origin Documentation/RelNotes/1.7.11.2.txt
  8d141a1d56

  real    0m0.010s
  user    0m0.008s
  sys     0m0.000s

Note that the output is produced almost instantaneously in
the first case, and then git uselessly spends a long time
looking for the next commit to touch that file (but there
isn't one, and we traverse all the way down to the roots).

6eafa6d096 submodules: don't stumble over symbolic links when cloning recursively
Since 69c3051 (submodules: refactor computation of relative gitdir path)
cloning a submodule recursively fails for nested submodules when a
symbolic link is part of the path to the work tree of the superproject.

This happens when module_clone() tries to find the relative paths between
the work tree and the git dir. When a symbolic link in current $PWD points
to a directory that is at a different level, then determining the number
of "../" needed to traverse to the superproject's work tree leads to a
wrong result.

As there is no portable way to say "pwd -P", use cd_to_toplevel to remove
the link from $PWD, which fixes this problem.

A test for this issue has been added to t7406.

b60e188c51 Strip namelen out of ce_flags into a ce_namelen field
Strip the name length from the ce_flags field and move it
into its own ce_namelen field in struct cache_entry. This
will both give us a tiny bit of a performance enhancement
when working with long pathnames and is a refactoring for
more readability of the code.

It enhances readability, by making it more clear what
is a flag, and where the length is stored and make it clear
which functions use stages in comparisions and which only
use the length.

It also makes CE_NAMEMASK private, so that users don't
mistakenly write the name length in the flags.

f8b090386b index-pack: loop while inflating objects in unpack_data
When the unpack_data function is given a consume() callback,
it unpacks only 64K of the input at a time, feeding it to
git_inflate along with a 64K output buffer.  However,
because we are inflating, there is a good chance that the
output buffer will fill before consuming all of the input.
In this case, we need to loop on git_inflate until we have
fed the whole input buffer, feeding each chunk of output to
the consume buffer.

The current code does not do this, and as a result, will
fail the loop condition and trigger a fatal "serious inflate
inconsistency" error in this case.

While we're rearranging the loop, let's get rid of the
extra last_out pointer. It is meant to point to the
beginning of the buffer that we feed to git_inflate, but in
practice this is always the beginning of our same 64K
buffer, because:

  1. At the beginning of the loop, we are feeding the
     buffer.

  2. At the end of the loop, if we are using a consume()
     function, we reset git_inflate's pointer to the
     beginning of the buffer.  If we are not using a
     consume() function, then we do not care about the value
     of last_out at all.

ea2d4ed359 commit: fix "--amend --only" with no pathspec
When we do not have any pathspec, we typically disallow an
explicit "--only", because it makes no sense (your commit
would, by definition, be empty). But since 6a74642
(git-commit --amend: two fixes., 2006-04-20), we have
allowed "--amend --only" with the intent that it would amend
the commit, ignoring any contents staged in the index.

However, while that commit allowed the combination, we never
actually implemented the logic to make it work. The current
code notices that we have no pathspec and assumes we want to
do an as-is commit (i.e., the "--only" is ignored).

Instead, we must make sure to follow the partial-commit
code-path. We also need to tweak the list_paths function to
handle a NULL pathspec.

daba53aeaf sha1_name.c: add support for disambiguating other types
This teaches the revision parser that in "$name:$path" (used for a

There are many more places where we know what types of objects are
called for.  This patch adds support for "commit", "treeish", "tree",
and "blob", which could be used in the following contexts:

 - "git apply --build-fake-ancestor" reads the "index" lines from
   the patch; they must name blob objects (not even "blob-ish");

 - "git commit-tree" reads a tree object name (not "tree-ish"), and
   zero or more commit object names (not "committish");

 - "git reset $rev" wants a committish; "git reset $rev -- $path"
   wants a treeish.

They will come in later patches in the series.

6269b6b676 sha1_name.c: get_describe_name() by definition groks only commits
Teach get_describe_name() to pass the disambiguation hint down the
callchain to get_short_sha1().

Also add tests to show various syntactic elements that we could take
advantage of the object type information to help disambiguration of
abbreviated object names.  Many of them are marked as broken, and
some of them will be fixed in later patches in this series.
