37ef39c929 suppress "(Recording state in git)" message when committing change to remote state
This was shown redundantly for a tricky reason -- while it runs
inside a doSideAction block that would appear to supress it,
the action being run is in a different state monad; for the remote,
and so the suppression doesn't work.

Always suppressing the message when committing to a local remote is
ok do to though -- it mirrors the /dev/nulling of the git annex shell commit
output. And it turns out that any time there is a git-annex branch state
change to commit on the remote, the local repo has also had a similar
change made, and so the message has been shown already.

eb6cb1b87f Add support for core.worktree, and fix support for GIT_WORK_TREE and GIT_DIR.
The environment needs to override git-config. Changed when git config is
read, and avoid rereading it once it's been read.

chdir for both worktree settings.

bb4f31a0ee Clean up handling of git directory and git worktree.
Baked into the code was an assumption that a repository's git directory
could be determined by adding ".git" to its work tree (or nothing for bare
repos). That fails when core.worktree, or GIT_DIR and GIT_WORK_TREE are
used to separate the two.

This was attacked at the type level, by storing the gitdir and worktree
separately, so Nothing for the worktree means a bare repo.

A complication arose because we don't learn where a repository is bare
until its configuration is read. So another Location type handles
repositories that have not had their config read yet. I am not entirely
happy with this being a Location type, rather than representing them
entirely separate from the Git type. The new code is not worse than the
old, but better types could enforce more safety.

Added support for core.worktree. Overriding it with -c isn't supported
because it's not really clear what to do if a git repo's config is read, is
not bare, and is then overridden to bare. What is the right git directory
in this case? I will worry about this if/when someone has a use case for
overriding core.worktree with -c. (See Git.Config.updateLocation)

Also removed and renamed some functions like gitDir and workTree that
misused git's terminology.

One minor regression is known: git annex add in a bare repository does not
print a nice error message, but runs git ls-files in a way that fails
earlier with a less nice error message. This is because before --work-tree
was always passed to git commands, even in a bare repo, while now it's not.

f7d8982672 Fix use of several config settings
annex.ssh-options, annex.rsync-options, annex.bup-split-options.

And adjust types to avoid the bugs that broke several config settings
recently. Now "annex." prefixing is enforced at the type level.

6d61067599 rsync shellescape disable option
Rsync special remotes can be configured with shellescape=no to avoid shell
quoting that is normally done when using rsync over ssh. This is known to
be needed for certian rsync hosting providers (specificially
hidrive.strato.com) that use rsync over ssh but do not pass it through the
shell.

This option avoids gpg key distribution, at the expense of flexability, and

4eb5112681 rationalize getConfig
getConfig got a remote-specific config, and this confusing name caused it
to be used a couple of places that only were interested in global configs.
Rename to getRemoteConfig and make getConfig only get global configs.

There are no behavior changes here, but remote.<name>.annex-web-options
never actually worked (and per-remote web options is a very unlikely to be
useful case so I didn't make it work), so fix the documentation for it.

b27760aa68 Work around a bug in rsync (IMHO) introduced by openSUSE's SIP patch.
openSUSE patches rsync with a patch adding SIP protocol support.
https://gist.github.com/2026167

With this patch, running rsync with no hostname parameter is apparently
supposed to list SIP hosts on the network. Practically, it does nothing
and exits 0.

git-annex uses rsync in a very special way to allow git-annex-shell to be
run on the remote host, and so did not need to specify a hostname, or a
file to transfer as a rsync parameter. So it sent ":", a degenerate case of
"host:file".

But the patch cannot differentiate ":" with no host parameter
(a bug in the SIP patch surely).

Results were that getting files failed, as rsync seemed to succeed, but the
requested file failed to arrive. Also I think that sending files will
make git-annex think a file has been transferred to the remote when
really rsync does nothing.

The workaround for this buggy rsync patch is to use "dummy:" as the
hostname.

receiving.

c3fbe07d7a do a cleanup commit after moving data from or to a git remote
Added Annex.cleanup, which is a general purpose interface for adding
actions to run at the end.

Remotes with the old git-annex-shell will commit every time, and have no
commit command, so hide stderr when running the commit command.

cbaebf538a rework git check-attr interface
Now gitattributes are looked up, efficiently, in only the places that
really need them, using the same approach used for cat-file.

The old CheckAttr code seemed very fragile, in the way it streamed files
through git check-attr.
I actually found that cad8824852
was still deadlocking with ghc 7.4, at the end of adding a lot of files.
This should fix that problem, and avoid future ones.

The best part is that this removes withAttrFilesInGit and withNumCopies,
which were complicated Seek methods, as well as simplfying the types
for several other Seek methods that had a Backend tupled in.

9030f68452 When checking that an url has a key, verify that the Content-Length, if available, matches the size of the key.
If there's no Content-Length, or the key has no size, this check is not
done, but it should happen most of the time, and protect against web
content that has changed.

b81d662cbf Avoid repeated location log commits when a remote is receiving files.
Done by adding a oneshot mode, in which location log changes are written to
the journal, but not committed. Taking advantage of git-annex's existing
ability to recover in this situation.

This is used by git-annex-shell and other places where changes are made to
a remote's location log.

303666965a Revert "Avoid creating ~/.bup when initializing a bup remote"
This reverts commit 6da40100c9.

On closer examinaton, this change is wrong. The bup special remote
can be configured with "buprepo=", which makes it use the default
~/.bup repo. This change makes it use a different temp dir each time,
which I'm sure would not be appreciated by anyone with that
configuration.

Bup insisting in creating ~/.bup even when using a different repo
does seem like a bug in *something*, but I'm leaning toward the bug
being in bup itself.

ce5637498f remove Utility.Conditional and use IfElse
This drops the >>! and >>? with the nice low fixity. IfElse does have

Anyway, using whenM and unlessM is easier; I sometimes mixed the operators
up.

47250a153a ssh connection caching
Ssh connection caching is now enabled automatically by git-annex. Only one
ssh connection is made to each host per git-annex run, which can speed some
things up a lot, as well as avoiding repeated password prompts. Concurrent
git-annex processes also share ssh connections. Cached ssh connections are
shut down when git-annex exits.

Note: The rsync special remote does not yet participate in the ssh
connection caching.

effaa298fa optimise fsck --from normal git remotes
For a local git remote, can symlink the file.
For a git remote using rsync, can preseed any local content.

There are a few reasons to use fsck --from on a normal git remote.
One is if it's using gitosis or similar, and you don't have shell access
to run git annex locally. Another reason could be if you just want to
fsck certian files of a bare remote.

f161b5eb59 Fix data loss bug in directory special remote
When moving a file to the remote failed, and partially transferred content
was left behind in the directory, re-running the same move would think it
succeeded and delete the local copy.

I reproduced data loss when moving files to a partition that was almost
full. Interrupting a transfer could have similar results.

Easily fixed by using a temp file which is then moved atomically into place
once the transfer completes.

I've audited other calls to copyFileExternal, and other special remote
file transfer code; everything else seems to use temp files correctly
(rsync, git), or otherwise use atomic transfers (bup, S3).
