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.

~/.config/git-annex/program, when possible.
Most of the time, there will be no discreprancy between programPath and
readProgramFile.
But, the programFile might have been written by an old version of git-annex
that is still installed, while a newer one is currently running. In this
case, we want to run the same one that's currently running.
This is especially important for things like the GIT_SSH=git-annex used for
ssh connection caching.
The only code that still uses readProgramFile directly is the upgrade code,
which needs to know where the standalone git-annex was installed, in order to
upgrade it.

push, as long as the remote branch is an ancestor of the local branch, to better support bare git repos.
See my comment in the bug report for analysis; basically this is safe
because it's a non-forced push, so won't lose history. Even if it was a
forced push or somehow races, things will eventually become consistent and
no git-annex branch info will be lost.
(This used to be done, but it forgot to do it since version 4.20130909.)

In this case there must be staged changes in the index (if there is
anything to unannex), and the unannex code path needs to run with a clean
index.

Turns out sqlite does not like having its database deleted out from
underneath it. It might suffice to empty the table, but I would rather
start each fsck over with a new database, so I added a lock file, and
running incremental fscks use a shared lock.
This leaves one concurrency bug left; running two concurrent fsck --more
will lead to: "SQLite3 returned ErrorBusy while attempting to perform step."
and one or both will fail. This is a concurrent writers problem.

Database.Handle can now be given a CommitPolicy, making it easy to specify
transaction granularity.
Benchmarking the old git-annex incremental fsck that flips sticky bits
to the new that uses sqlite, running in a repo with 37000 annexed files,
both from cold cache:
old: 6m6.906s
new: 6m26.913s

This makes interrupt and resume work, robustly.
But, incremental fsck is slowed down by all those transactions..

Did not keep backwards compat for sticky bit records. An incremental fsck
that is already in progress will start over on upgrade to this version.
This is not yet ready for merging. The autobuilders need to have sqlite
installed.
Also, interrupting a fsck --incremental does not commit the database.
So, resuming with fsck --more restarts from beginning.
Memory: Constant during a fsck of tens of thousands of files.
(But, it does seem to buffer whole transation in memory, so
may really scale with number of files.)

* sync: Use the ssh-options git config when doing git pull and push.
* remotedaemon: Use the ssh-options git config.
Note that the rename env var means that if a new git-annex calls an old one
for git-annex ssh, or a new calls an old, nothing much will go wrong;
just ssh caching won't happen.

the commit message fixed rather than calculating it after every commit. It

--deduplicate, --skip-duplicates, and --clean-duplicates still checksum the
file twice, the first time to determine if it's a duplicate. This cannot be
easily merged with the checksumming done to add the file, since the file
needs to be locked down before that second checksum is taken.

This reverts commit 961b5d4d997999485e7b696416574cd0f8663f88.
This broke unit and test suite cleanup. The difference is that
dirContentsRecursive only returns files, but this needs to also operate on
directories.

I hope this doesn't impact speed much -- it does have to pull out a value
from Annex state every time it accesses the branch now.
The test case I dropped has never caught any problems that I can remember,
and would have been rather difficult to convert.

This is necessary for interop between inode caches created on unix and
windows. Which is more important than supporting inodecaches for large keys
with the wrong size, which are broken anyway.
There should be no slowdown from this change, except on Windows.

Avoid using fileSize which maxes out at just 2 gb on Windows.
Instead, use hFileSize, which doesn't have a bounded size.
Fixes support for files > 2 gb on Windows.
Note that the InodeCache code only needs to compare a file size,
so it doesn't matter it the file size wraps. So it has been
left as-is. This was necessary both to avoid invalidating existing inode
caches, and because the code passed FileStatus around and would have become
more expensive if it called getFileSize.

* info: Can now display info about a given uuid.
* Added to remote/uuid info: Count of the number of keys present
on the remote, and their size. This is rather expensive to calculate,
so comes last and --fast will disable it.
* Git remote info now includes the date of the last sync with the remote.

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.

I think this is the last problimatic setCurrentDirectory. I also audited
for extrnal commands that git-annex might run with cwd = foo, and did not
find any that were passed any FilePath that might be absolute.

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.

and so fail.
In the case where a remote of the bare repo has a fetch = configuration,
refs/remotes/origin/master will exist, and so the merge code path tried to
run in the bare repo.

Avoids an intractable problem that prevents the pre-commit hook from
telling if such a file is intended to be an annexed file or not.

The url log could have an url for a key, while the location log thinks it's
not present in the web. In this case, addurl --file url would not do
anything. Fixed it to re-add the web as a location.
I don't know how this situation could arise, but I saw it in the wild in
the conference_proceedings repo, affecting key
URL-s17806003--http://mirror.linux.org.au/pub/linux.conf.au/2014/Wednesday/53-Building_Effective_Alliances_around_the_Trans-Pacific_Partnershi-c0505b631127ccc67e38e637344d988e
Investigating the presence log, it looked like that key
was originally listed as present in the web, then in commit
56abf9e9f3e691ed9d83513037d4019313321ca3 someone else's git-annex
set it and some other things to not present in the web. It would be
interesting to know what that user did, but I doubt I'll be able to find
out. All I can tell from this investigation is that the inconsistency was
not introduced when originally addurl-ing the url.
