The code initializing the merge driver registry accidentally
forgot a `goto done` in case of an error. Because of this the
next line, which registers the global shutdown callback for the
merge drivers, is only called when an error occured.
Fix this by adding the missing `goto done`. This fixes some
memory leaks when the global state is shut down.
Clang's documentation parser, which we use in our documentation system
does not report any comments for functions which use size_t as a type.
The root cause is buried somewhere in libclang but we can work around it
by defining the type ourselves. This typedef makes sure that libclang
sees it and that we do not change its size.
The xdl_prepare_env() function may initialise an xdlclassifier_t
data structure via xdl_init_classifier(), which allocates memory
to several fields, for example 'rchash', 'rcrecs' and 'ncha'.
If this function later exits due to the failure of xdl_optimize_ctxs(),
then this xdlclassifier_t structure, and the memory allocated to it,
is not cleaned up.
In order to fix the memory leak, insert a call to xdl_free_classifier()
before returning.
This patch was originally written by Ramsay Jones (see commit

Commit 307ab20b3 ("xdiff: PATIENCE/HISTOGRAM are not independent option
bits", 19-02-2012) introduced the XDF_DIFF_ALG() macro to access the
flag bits used to represent the diff algorithm requested. In addition,
code which had used explicit manipulation of the flag bits was changed
to use the macros.
However, one example of direct manipulation remains. Update this code to
use the XDF_DIFF_ALG() macro.

If we hit the EOF while trying to write a new value, it may be that
we're already in the section that we were looking for. If so, do not
write a (duplicate) section header, just write the value.
Iterator tests were split over repo::iterator and diff::iterator,
with duplication between the two. Move them to iterator::index,
iterator::tree, and iterator::workdir.
Prior iterator implementations returned `GIT_ENOTFOUND` when
trying to advance into empty directories. Ensure that we no longer
do that and simply handle them gracefully.
tree_iterator was only working properly for a pathlist containing
file paths. In case of directory paths, it didn't match children
which contradicts GIT_DIFF_DISABLE_PATHSPEC_MATCH and
is different from index_iterator and fs_iterator.
As a consequence head-to-index status reporting for a specific
directory did not work properly -- all files have been reported
as added.
Include additional tests.
In the workdir iterator we do some tricky things to step down into
directories to look for things that are in our pathlist. Make sure
that we don't confuse between folders that we're definitely going to
return everything in and folders that we're only stepping down into
to keep looking for matches.
Ensure that we have hit the end of iteration; previously we tested
that we saw all the values that we expected to see. We did not
then ensure that we were at the end of the iteration (and that there
were subsequently values in the iteration that we did *not* expect.)
Drop some of the layers of indirection between the workdir and the
filesystem iterators. This makes the code a little bit easier to
follow, and reduces the number of unnecessary allocations a bit as
well. (Prior to this, when we filter entries, we would allocate them,
filter them and then free them; now we do the filtering before
allocation.)
Also, rename `git_iterator_advance_over_with_status` to just
`git_iterator_advance_over`. Mostly because it's a fucking long-ass
function name otherwise.
