We will be using the same "rev-list --verify-objects" logic to add a
sanity check to the receiving end of "git push" in the same way, but the
list of commits that are checked come from a structure with a different
shape over there.
Update the function to take an iterator to make it easier to reuse it in
different contexts.

The "git fetch" command works in two phases. The remote side tells us what
objects are at the tip of the refs we are fetching from, and transfers the
objects missing from our side. After storing the objects in our repository,
we update our remote tracking branches to point at the updated tips of the
refs.
A broken or malicious remote side could send a perfectly well-formed pack
data during the object transfer phase, but there is no guarantee that the
given data actually fill the gap between the objects we originally had and
the refs we are updating to.
Although this kind of breakage can be caught by running fsck after a
fetch, it is much cheaper to verify that everything that is reachable from
the tips of the refs we fetched are indeed fully connected to the tips of
our current set of refs before we update them.

It makes no sense to do the - possibly very expensive - call to "rev-list
<new-ref-sha1> --not --all" in check_for_new_submodule_commits() when
there aren't any submodules configured.
Leave check_for_new_submodule_commits() early when no name <-> path
mappings for submodules are found in the configuration. To make that work
reading the configuration had to be moved further up in cmd_fetch(), as
doing that after the actual fetch of the superproject was too late.

The %(body) placeholder returns the whole body of a tag or
commit, including the signature. However, callers may want
to get just the body without signature, or just the
signature.
Rather than change the meaning of %(body), which might break
some scripts, this patch introduces a new set of
placeholders which break down the %(contents) placeholder
into its constituent parts.

Generally the format of a git tag or commit message is:
subject
body body body
body body body
However, we occasionally see multiline subjects like:
subject
with multiple
lines
body body body
body body body
The rest of git treats these multiline subjects as something
to be concatenated and shown as a single line (e.g., "git
log --pretty=format:%s" will do so since f53bd74). For
consistency, for-each-ref should do the same with its
"%(subject)".

The find_subpos function was a little hard to use, as well
as to read. It would sometimes write into the subject and
body pointers, and sometimes not. The body pointer sometimes
could be compared to subject, and sometimes not. When
actually duplicating the subject, the caller was forced to
figure out again how long the subject is (which is not too
big a deal when the subject is a single line, but hard to
extend).
The refactoring makes the function more straightforward, both
to read and to use. We will always put something into the
subject and body pointers, and we return explicit lengths
for them, too.
This lays the groundwork both for more complex subject
parsing (e.g., multiline), as well as splitting the body
into subparts (like the text versus the signature).

Use strbuf to replace some string operations, since it is cleaner and

Passing a prefix to a function that is supposed to find the prefix is
strange. And it's really only used if the pathspec is NULL. Make the
callers handle this case instead.
As we are always returning a fresh copy of a string (or NULL), change the
type of the returned value to non-const "char *".

Push can not set the commit note "mediawiki_revision:" and update the
remote reference. This avoids having to "git pull --rebase" after each
push, and is probably more natural. Make it the default, but let it be

Implement a gate between git and mediawiki, allowing git users to push
and pull objects from mediawiki just as one would do with a classic git
repository thanks to remote-helpers.
The following packages need to be installed (available on common
repositories):
libmediawiki-api-perl
libdatetime-format-iso8601-perl
Use remote helpers in order to be as transparent as possible to the git
user.
Download Mediawiki revisions through the Mediawiki API and then
fast-import into git.
Mediawiki revision number and git commits are linked thanks to notes
bound to commits.
The import part is done on a refs/mediawiki/<remote> branch before
coming to refs/remote/origin/master (Huge thanks to Jonathan Nieder
for his help)
We use UTF-8 everywhere: use encoding 'utf8'; does most of the job, but
we also read the output of Git commands in UTF-8 with the small helper
run_git, and write to the console (STDERR) in UTF-8. This allows a
seamless use of non-ascii characters in page titles, but hasn't been
tested on non-UTF-8 systems. In particular, UTF-8 encoding for filenames
could raise problems if different file systems handle UTF-8 filenames
differently. A uri_escape of mediawiki filenames could be imaginable, and
is still to be discussed further.
Partial cloning is supported using one of:
git clone -c remote.origin.pages='A_Page Another_Page' mediawiki::http://wikiurl
git clone -c remote.origin.categories='Some_Category' mediawiki::http://wikiurl
git clone -c remote.origin.shallow='True' mediawiki::http://wikiurl
Thanks to notes metadata, it is possible to compare remote and local last
mediawiki revision to warn non-fast forward pushes and "everything
up-to-date" case.
When allowed, push looks for each commit between remotes/origin/master
and HEAD, catches every blob related to these commit and push them in
chronological order. To do so, it uses git rev-list --children HEAD and
travels the tree from remotes/origin/master to HEAD through children. In
other words:
* Shortest path from remotes/origin/master to HEAD
* For each commit encountered, push blobs related to this commit

Often we want to verify everything reachable from a given set of commits
are present in our repository and connected without a gap to the tips of
our refs. We used to do this for this purpose:
$ rev-list --objects $commits_to_be_tested --not --all
Even though this is good enough for catching missing commits and trees,
we show the object name but do not verify their existence, let alone their
well-formedness, for the blob objects at the leaf level.
Add a new "--verify-object" option so that we can catch missing and broken
blobs as well.
