We don't need the parsed objects at this point, merely the
information that they have marks.

Seems to be three times faster in my setup with lots of objects.

We read from the marks file and keep only marked commits, but in
order to find the type of object, we are parsing the whole thing,
which is slow, specially in big repositories with lots of big files.

There's no need for that, we can query the object information with
sha1_object_info().

Before this, loading the objects of a fresh emacs import, with 260598
blobs took 14 minutes, after this patch, it takes 3 seconds.

This is the way fast-import does it. Also die if the object is not
found (like fast-import).

In the !delta_data error path of unpack_entry(), we run free(base).
This became a window for use-after-free() in abe601bb (sha1_file:
remove recursion in unpack_entry, 2013-03-27), as follows:

Before abe601bb, we got the 'base' from cache_or_unpack_entry(..., 0);
keep_cache=0 tells it to also remove that entry.  So the 'base' is at
this point not cached, and freeing it in the error path is the right
thing.

After abe601bb, the structure changed: we use a three-phase approach
where phase 1 finds the innermost base or a base that is already in
the cache.  In phase 3 we therefore know that all bases we unpack are
not part of the delta cache yet.  (Observe that we pop from the cache
in phase 1, so this is also true for the very first base.)  So we make
no further attempts to look up the bases in the cache, and just call
add_delta_base_cache() on every base object we have assembled.

But the !delta_data error path remained unchanged, and now calls
free() on a base that has already been entered in the cache.  This
means that there is a use-after-free if we later use the same base
again.

So remove that free(); we are still going to use that data.

There should be no functional changes.

The only reason I wrapped this code around a sub-function is because zsh
did the same in it's bashcompinit script in order to declare the special
variable 'words' as hidden, but only in this context.

There's no need for that any more since we access __git_main directly,
so 'words' is not modified, so there's no need for the sub-function.

In zsh mode the array indexes are different though.

We call File::Temp's "tempfile" function as a class method, but it was
never designed to be called this way. Older versions seemed to
tolerate it, but as of File::Temp 0.23, it blows up like this:

  $ git svn fetch
  'tempfile' can't be called as a method at .../Git.pm line 1117.

Fix it by calling it as a regular function, just inside the File::Temp
namespace.

  t/Makefile: remove smoke test targets

Commit d24fbca7 (Remove Git's support for smoke testing - 2011-12-23)
removed the smoke test support from the test suite but it was
re-added by commit 342e9ef2 (Introduce a performance testing
framework - 2012-02-17).  This appears to be the result of a
mis-rebase, since re-adding the smoke testing infrastructure does
not relate to the subject of that commit.

The current 'smoke' target is broken since the 'harness' script it
uses no longer exists, so just reapply this section of commit d24fbca7
and remove all of the smoke testing section in the makefile.

* nd/pretty-formats:
  pretty: Fix bug in truncation support for %>, %< and %><

Some systems experience failures in t4205-*.sh (tests 18-20, 27)
which all relate to the use of truncation with the %< padding
placeholder. This capability was added in the commit a7f01c6b
("pretty: support truncating in %>, %< and %><", 19-04-2013).

The truncation support was implemented with the assistance of a
new strbuf function (strbuf_utf8_replace). This function contains
the following code:

       strbuf_attach(sb_src, strbuf_detach(&sb_dst, NULL),
                     sb_dst.len, sb_dst.alloc);

Unfortunately, this code is subject to unspecified behaviour. In
particular, the order of evaluation of the argument expressions
(along with the associated side effects) is not specified by the
C standard. Note that the second argument expression is a call to
strbuf_detach() which, as a side effect, sets the 'len' and 'alloc'
fields of the sb_dst argument to zero. Depending on the order of
evaluation of the argument expressions to the strbuf_attach call,
this can lead to assigning an empty string to 'sb_src'.

In order to remove the undesired behaviour, we replace the above
line of code with:

       strbuf_swap(sb_src, &sb_dst);
       strbuf_release(&sb_dst);

which achieves the desired effect without provoking unspecified
behaviour.
