Unless busybox doesn't support readlink -f, then it just uses readlink and
symlinking won't work. Also, OSX has no readlink -f so not done there.
Thanks, jlebar.

I missed this because there's no strong type checking across the AJAX call. :(
Need to switch to Fay to avoid such bugs..
When setting up a remote on a ssh server, prompt for a password inside the
webapp, rather than relying on ssh's own password prompting in the terminal
the webapp was started from, or ssh-askpass.
Avoids double prompting for the ssh password (and triple-prompting on
windows for rsync.net), since the entered password is cached for 10 minutes
and this cached password is reused when setting up the repository, after
the initial probe.
When the user has an existing ssh key set up, they can choose to use it,
rather than entering a password. The webapp used to probe for this case
automatically, so this is a little harder, but it's an advanced user thing.
Note that this commit is known to break enabling existing rsync
repositories. It hs not been tested with gcrypt repositories. It's not been
successfully tested yet on Windows.

* webapp: Support using git-annex on a remote server, which was installed
from the standalone tarball or OSX app, and so does not have
git-annex in PATH (and may also not have git or rsync in PATH).
* standalone tarball, OSX app: Install a ~/.ssh/git-annex-wrapper, which
can be used to run git-annex, git, rsync, etc.
To do so, I slightly changed the behavior of unannex. Now in fast mode, it
only makes a hard link when the annexed file's link count is 1. This avoids
unannexing 2 files with the same content in fast mode from hard linking
them together. (One will end up hard linked to the annex, which the docs
warn about.)
With that change, uninit can simply always run unannex in fast mode. Since
.git/annex/objects is being blown away anyway, there's no worry in this
case about a hard link pointing into it causing an annexed object to be
modified.
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.

Code was still buggy, it turns out (though the recursion checker caught
it). In the case of (Schedule (Monthly Nothing) AnyTime), where the last
run was on yyyy-12-31, it looped forever.
Also, the handling of (Schedule (Yearly Nothing) AnyTime) was wacky where
the last run was yyyy-12-31. It would suggest a window starting on the 3rd
for the next run (because 31 mod 28 is 3).
I think that originally I was wanted to avoid running on 01-01 if it had
just run on 12-31. But the code didn't accomplish this, and it's not
necessary anyway. This is supposed to calculate the next window meeting the
schedule, and for (Schedule (Monthly Nothing), the window starts at 01-01
and runs through 01-31. If that causes two back-to-back runs, well the next
one will not be until 02-01 at the earliest.
Also, back-to-back runs can be avoided, if desired, by using Divisible 2.
a ssh remote, and pulls.
XMPP is no longer needed in this configuration!
Requires the remote server have git-annex-shell with notifychanges support.

This will be used by the remote-daemon to quickly tell when changes have
been pushed from some other repository into a ssh remote.
Adjusted the remote-daemon protocol to communicate changed shas, rather
than git branch refs. This way, it can easily check if a sha is new.

This includes checking when dropping files that any required content
configuration is satisfied. However, it does not yet include an active
check on the required content; the location log is trusted when checking
the required content expression.
Version 5.20140227 broke creation of glacier repositories, not including
the datacenter and vault in their configuration. This bug is fixed, but
glacier repositories set up with the broken version of git-annex need to
have the datacenter and vault set in order to be usable. This can be done
using git annex enableremote to add the missing settings. For details, see

Motivation: Hook scripts for nautilus or other file managers
need to provide the user with feedback that a file is being downloaded.

Note that this is a nearly entirely free feature. The data was already
stored in the metadata log in an easily accessible way, and already was
parsed to a time when parsing the log. The generation of the metadata
fields may even be done lazily, although probably not entirely (the map
has to be evaulated to when queried).
For example "standard or (include=otherdir/*)" or even "not standard"
Note that the implementation avoids any potential for loops (if a
standard preferred content expression itself mentioned standard).

Old ssh did not check the hostname passed to -O stop, so I had used "any".
But now ssh does check it! I think this happened as part of the client-side
hostname canonicalization changes in 6.5p1, but have not verified that
introduced the problem.
The symptom was that it would try to dns lookup "any", which often caused a
bit of a delay at shutdown. And the old ssh connection kept running, so
it would do it over and over again.
Fixed by using localhost, which hopefully reliably resolves to some address
that ssh will accept.. Also nukeFile the socket after ssh has been asked to
shutdown, just in case.
From 1.7 gb to 900 mb on 300 thousand unique reported shas.
When shas are not unique, this streams much better than before, so won't
buffer the full list before putting them into the Set and throwing away
dups. And when fsck output includes ignorable lines, especially
dangling object lines, they won't be buffered in memory at all.
unused: In direct mode, files that are deleted from the work tree are no longer incorrectly detected as unused.
Direct mode `git annex info` slows down a bit due to more stringent
checking, but not by a lot.
Benchmarking this with 1000 small files being copied, the time reduced from
15.98s to 14.64s -- an 8% improvement in the non-data-transfer overhead of
git-annex copy.
git-annex-shell does not need a pty, so this speeds things up.
Also, it may avoid weird misconfigured systems that try to run screen or
tmux on every ssh login from doing so.
This is a new feature, it was not handled before, since it's a bit of an
edge case. However, it can be handled exactly the same as a file/dir
conflict, just leave the non-annexed item alone.
While implementing this, the core resolveMerge' function got a lot simpler
and clearer. Note especially that where before there was an asymetric call to
stagefromdirectmergedir, now graftin is called symmetrically in both cases.
And, in order to add that `graftin us`, the current branch needed to be
known (if there is no current branch, there cannot be a merge conflict).
This led to some cleanups of how autoMergeFrom behaved when there is no
current branch.

Added test cases for both ways this can happen, with a conflict involving a
file, or a directory.
Cleaned up resolveMerge to not touch the work tree in direct mode, which
turned out to be the only way to handle things.. And makes it much nicer.
Still need to run test suite on windows.
Using the extract(1) program to do the heavy lifting.
Decided to make git-annex run pre-commit-annex when committing. Since
git-annex pre-commit also runs it, it'll be run when git commit is run too,
via the pre-commit hook. This basically gives back the pre-commit hook
that git-annex took away. The implementation avoids repeatedly looking
for the hook script when the assistant is running and committing
repeatedly; only checks if the hook is available once.
To make the script simpler, made git-annex metadata -s field?=value
only set a field when it's not already got a value.
