c784ef4586 unify exception handling into Utility.Exception
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.

76d894f2e5 Display exception message when a transfer fails due to an exception.
For example, I had a copy to a remote that was failing for an unknown
reason. This let me see the exception was createDirectory: permission
denied; the underlying problem being a permissions issue.

bc9e4697b9 better type for Retriever
Putting a callback in the Retriever type allows for the callback to
remove the retrieved file when it's done with it.

I did not really want to make Retriever be fixed to Annex Bool,
but when I tried to use Annex a, I got into some type of type mess.

47e522979c allow Retriever action to update the progress meter
Needed for eg, Remote.External.

Generally, any Retriever that stores content in a file is responsible for
updating the meter, while ones that procude a lazy bytestring cannot update
the meter, so are not asked to.

61a35de433 Deal with change in git 2.0 that made indirect mode merge conflict resolution leave behind old files.
I think this is a git behavior change, but have not checked to be sure.
Conflict cruft used to look like $foo~HEAD, but now just $foo is left
behind as conflict cruft.

With test case.

1efa51f344 direct: Fix handling of case where a work tree subdirectory cannot be written to due to permissions.
Running `git annex direct` would cause loss of data, because the object
was moved to a temp file, which it then tried to replace the work tree file
with, and on failure, the temp file got deleted. Now it's instead moved
back into the annex object location.

d9d76cf98b Fix minor FD leak in journal code.
Minor because normally only 1 FD is leaked per git-annex run. However,
the test suite leaks a few hundred FDs, and this broke it on the Debian
autobuilders, which seem to have a tigher than usual ulimit.

The leak was introduced by the lazy getDirectoryContents' that was
introduced in e6330988dd in order to scale to
millions of journal files -- if the lazy list was never fully consumed, the
directory handle did not get closed.

Instead, pull in openDirectory/readDirectory/closeDirectory code that I
already developed and submitted in a patch to the haskell directory library
earlier. Using this in journalDirty avoids the place that the lazy list
caused a problem. And using it in stageJournal eliminates the need for
getDirectoryContents'.

The getJournalFiles* functions are switched back to using the regular
strict getDirectoryContents. I'm not sure if those always consume the whole
list, so this avoids any leak. And the things that call those are things
like git annex unused, which also look at every file committed to the
git-annex branch, so would need more work to scale to insane numbers of
files anyway.

ba42b67c70 Fix bug in automatic merge conflict resolution
When one side is an annexed symlink, and the other side is a non-annexed symlink.

In this case, git-merge does not replace the annexed symlink in the work
tree with the non-annexed symlink, which is different from it's handling of
conflicts between annexed symlinks and regular files or directories.
So, while git-annex generated the correct merge commit, the work tree
didn't get updated to reflect it.
See comments on bug for additional analysis.

Did not add this to the test suite yet; just unloaded a truckload of firewood
and am feeling lazy.

support commit.gpgsign
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.

d0c1a22e7c import metadata from feeds
When annex.genmetadata is set, metadata from the feed is added to files
that are imported from it.

Reused the same feedtitle and itemtitle, feedauthor, itemauthor, etc names
that are used in --template.

Also added title and author, which are the item title/author if available,
falling back to the feed title/author. These are more likely to be common
metadata fields.

(There is a small bit of dupication here, but once git gets
around to packing the object, it will compress it away.)

The itempubdate field is not included in the metadata as a string; instead
it is used to generate year and month fields, same as is done when adding
files with annex.genmetadata set.

b30de0dfd2 work around a bug in git
http://marc.info/?l=git&m=140262402204212&w=2

This git bug manifested on FAT and Windows as the test suite failing in 3
places. All involved merge conflict resolution. It turned out that the
associated file mappings were getting messed up, and that happened because
this git bug lost track of what files were supposed to be symlinks.

4fe2e53f5b finish fixing windows timezone madness
Rather than calculating the TSDelta once, and caching it, this now
reads the inode sential file's InodeCache file once, and then each time a
new InodeCache is generated, looks at the sentinal file to get the current
delta.

This way, if the time zone changes while git-annex is running, it will
adapt.

This adds some inneffiency, but only on Windows, and only 1 stat per new
file added. The worst innefficiency is that `git annex status` and
`git annex sync` will now (on Windows) stat the inode sentinal file once per
file in the repo.

It would be more efficient to use getCurrentTimeZone, rather than needing
to stat the sentinal file. This should be easy to do, once the time
package gets my bugfix patch.

e4d7e2ebde fix for Windows file timestamp timezone madness
On Windows, changing the time zone causes the apparent mtime of files to
change. This confuses git-annex, which natually thinks this means the files
have actually been modified (since THAT'S WHAT A MTIME IS FOR, BILL <sheesh>).

Work around this stupidity, by using the inode sentinal file to detect if
the timezone has changed, and calculate a TSDelta, which will be applied
when generating InodeCaches.

This should add no overhead at all on unix. Indeed, I sped up a few
things slightly in the refactoring.

Seems to basically work! But it has a big known problem:
If the timezone changes while the assistant (or a long-running command)
runs, it won't notice, since it only checks the inode cache once, and
so will use the old delta for all new inode caches it generates for new
files it's added. Which will result in them seeming changed the next time
it runs.

d6711800ad avoid bad commits after interrupted direct mode sync (or merge)
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.

pulled into the current one. And caches need to be invalidated for it
to be visible in the edit form.

95ca3bb022 Fix encoding of data written to git-annex branch. Avoid truncating unicode characters to 8 bits.
Allow any encoding to be used, as with filenames (but utf8 is the sane
choice). Affects metadata and repository descriptions, and preferred
content expressions.

The question of what's the right encoding for the git-annex branch is a
vexing one. utf-8 would be a nice choice, but this leaves the possibility
of bad data getting into a git-annex branch somehow, and this resulting in
git-annex crashing with encoding errors, which is a failure mode I want to
avoid.

(Also, preferred content expressions can refer to filenames, and filenames
can have any encoding, so limiting to utf-8 would not be ideal.)

The union merge code already took care to not assume any encoding for a
file. Except it assumes that any \n is a literal newline, and not part of
some encoding of a character that happens to contain a newline. (At least
utf-8 avoids using newline for anything except liternal newlines.)
Adapted the git-annex branch code to use this same approach.

Note that there is a potential interop problem with Windows, since
FileSystemEncoding doesn't work there, and instead things are always
decoded as utf-8. If someone uses non-utf8 encoding for data on the
git-annex branch, this can lead to an encoding error on windows. However,
this commit doesn't actually make that any worse, because the union merge
code would similarly fail with an encoding error on windows in that
situation.

There is a small behavior change here. Before, all commands would warn when
acting on an annexed file with an unknown backend. Now, only fsck and

15917ec1a8 sync, assistant, remotedaemon: Use ssh connection caching for git pushes and pulls.
For sync, saves 1 ssh connection per remote. For remotedaemon, the same
ssh connection that is already open to run git-annex-shell notifychanges
is reused to pull from the remote.

Only potential problem is that this also enables connection caching
when the assistant syncs with a ssh remote. Including the sync it does
when a network connection has just come up. In that case, cached ssh
connections are likely to be stale, and so using them would hang.
Until I'm sure such problems have been dealt with, this commit needs to
stay on the remotecontrol branch, and not be merged to master.
