This might be overkill; I only know I need it in ls-files, but other git
commands can also do their own globbing, it turns out, and I am pretty sure
I never want them too when git-annex is using them as plumbing.
Test suite still passes and it looks ok.
There's no good solution for git-annex here; I can't escape or un-escape
and avoid breaking in some cases, so I've chosen the combo least likely
to result in breakage.
Git really needs to fix its behavior here.
The only other thing git-annex could do is treat this as a feature,
and don't try to escape at all. Ugh.
Note that previously, `git annex find *.jpg` would find eg, foo/bar.jpg.
That was never intended or documented behavior, so I'm going to change it.
But this is potentially a behavior change if someone discovered that
behavior and relied on it despite it being accidental. Oh well.. can't make
an omlette w/o breaking some eggs.
Seen for example, a newly checked out git submodule. In this case,
.git/HEAD is a raw sha, rather than the usual reference to a ref.
Removed currentSha in passing, since it was a more roundabout way of
doing what headSha does, and headSha is more robust.
Seems to work, but still experimental until it's been tested more.
When repositories are on filesystems not supporting symlinks, the .git dir
symlink trick cannot be used. Since we're going to be in direct mode
anyway, the .git dir symlink is not strictly needed.
However, I have not fixed the code that creates new annex symlinks to
handle this case -- the committed symlinks will be wrong.
git annex sync happens to currently fail in a submodule using direct mode,
because there's no HEAD ref. That also needs to be dealt with to get
this fully working in crippled filesystems.
Leaving http://github.com/datalad/datalad/issues/44 open until these issues
are dealt with.
Avoids a warning message from git when HEAD doesn't exist. Which it won't
when eg, git-annex is used in a submodule just cloned with
git clone --recursive. In this case, a specific ref is checked out and
there's no HEAD yet.
The code already returned Nothing in this case, so no behavior change other
than not showing the warning. And git-annex operates fine in this
situation.

Unfortunately, this caused breakage on Windows, and possibly elsewhere,
because parentDir and takeDirectory do not behave the same when there is a
trailing directory separator.
parentDir is less safe than takeDirectory, especially when working
with relative FilePaths. It's really only useful in loops that
want to terminate at /

This allows the git repository to be moved while git-annex is running in
it, with fewer problems.
On Windows, this avoids some of the problems with the absurdly small
MAX_PATH of 260 bytes. In particular, git-annex repositories should
work in deeper/longer directory structures than before. See
http://git-annex.branchable.com/bugs/__34__git-annex:_direct:_1_failed__34___on_Windows/
There are several possible ways this change could break git-annex:
1. If it changes its working directory while it's running, that would
be Bad News. Good news everyone! git-annex never does so. It would also
break thread safety, so all such things were stomped out long ago.
2. parentDir "." -> "" which is not a valid path. I had to fix one
instace of this, and I should probably wipe all calls to parentDir out
of the git-annex code base; it was never a good idea.
3. Things like relPathDirToFile require absolute input paths,
and code assumes that the git repo path is absolute and passes it to it
as-is. In the case of relPathDirToFile, I converted it to not make
this assumption.
Currently, the test suite has 16 failures.
It's ok to probe every time for git-branch remove because that's
run quite rarely. For git-checkattr, it's run only once, when
starting the --batch mode, and so again the overhead is pretty minimal.
This leaves 2 places where the build version is still used.
git merge might be interactive or fail if one skews, and --no-gpg-sign
might not be pased, or might be passed to a git that doesn't understand it
if the other skews. It seems a little expensive to check the git version
each time these are used.
This doesn't seem likely to cause many problems, at least compared with
check-attr hanging on skew.
This allows bypassing the direct mode guard in a safe way to do all sorts
of things including git revert, git mv, git checkout ...

I had hoped that the git devs could change git's handling of partial
commits to not use a false index file, but seems not.
So, this relies on some git internals to detect that case. The test suite
has a test case added to catch it if changes to git break it.

This allows using Git.Remote w/o needing to have Git.BuildVersion, which
requires configure. It will simplify github-backup when these libraries are
used there.
Didn't know that this library existed!
This includes making git-annex not re-exec itself on start on windows, and
making the test suite on Windows run tests without forking.
Found these with:
git grep "^ " $(find -type f -name \*.hs) |grep -v ': where'
Unfortunately there is some inline hamlet that cannot use tabs for
indentation.
Also, Assistant/WebApp/Bootstrap3.hs is a copy of a module and so I'm
leaving it as-is.
This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.

* New annex.hardlink setting. Closes: #758593
* init: Automatically detect when a repository was cloned with --shared,
and set annex.hardlink=true, as well as marking the repository as
untrusted.
Had to reorganize Logs.Trust a bit to avoid a cycle between it and
Annex.Init.
Old behavior was to take the first fuzzy match. Now, it checks the globa
git config, and runs the normal fuzzy handling, including failing to run a
semi-random command by default.
Removed old extensible-exceptions, only needed for very old ghc.
Made webdav use Utility.Exception, to work after some changes in DAV's
exception handling.
Removed Annex.Exception. Mostly this was trivial, but note that
tryAnnex is replaced with tryNonAsync and catchAnnex replaced with
catchNonAsync. In theory that could be a behavior change, since the former
caught all exceptions, and the latter don't catch async exceptions.
However, in practice, nothing in the Annex monad uses async exceptions.
Grepping for throwTo and killThread only find stuff in the assistant,
which does not seem related.
Command.Add.undo is changed to accept a SomeException, and things
that use it for rollback now catch non-async exceptions, rather than
only IOExceptions.
The repair code assumed that if fsck found no broken objects, after
removing bad objects and possibly pulling replacements from remote, all was
well.. but this is not really true. Removing bad objects could leave some
branches broken. fsck doesn't report any missing objects in this case,
and its messages about broken branches are ignored by the fsck output
parser.
To deal with this, added a separate scan of all refs to find broken ones
and remove them when --forced. This will also let anyone who ran into this
bug run repair again to fix up the incomplete repair done before.

This is a security/usability tradeoff. To avoid exposing the gpg key ids
who can decrypt the repository, users can unset
gcrypt-publish-participants.
The gcrypt-publish-participants option is available in my fork of
git-remote-gcrypt.

Support users who have set commit.gpgsign, by disabling gpg signatures for
git-annex branch commits and commits made by the assistant.
The thinking here is that a user sets commit.gpgsign intending the commits
that they manually initiate to be gpg signed. But not commits made in the
background, whether by a deamon or implicitly to the git-annex branch.
gpg signing those would be at best a waste of CPU and at worst would fail,
or flood the user with gpg passphrase prompts, or put their signature on
changes they did not directly do.
See Debian bug #753720.
Also makes all commits done by git-annex go through a few central control
points, to make such changes easier in future.
Also disables commit.gpgsign in the test suite.

The bug caused the size of the queue to be miscalculted; it was doubled
each time an item was added. Commands run after approx 140 items rather
than the intended 10240!
It was possible for a interrupted sync or merge in direct mode to
leave the work tree out of sync with the last recorded commit.
This would result in the next commit seeing files missing from the work
tree, and committing their removal.
Now, a direct mode merge happens not only in a throwaway work tree, but using
a temporary index file, and without any commits or index changes
being made until the real work tree has been updated. If the merge is
interrupted, the work tree may have some updated files, but worst case a
commit will redundantly commit changes that come from the merge.
