It doesn't work, in a most puzzling way, which just wasted me hours, even
if XMPP libs are installed. Webapp too.

This reverts commit 699a90bdc195a67c5aa5fca34fcaa07fb2b530ae.
My windows build environment was broken; reverted to backup.

This used to work, but now hsc2hs is failing with a usage message.
Since I have not changed my windows build environment at all, it must be
some change due to a change in the cabal file. Perhaps too make flags are
causing it to hit a windows command line length limit?
Anyway, these hsc files did nothing on Windows, so can be omitted and not
built to work around yet another epic windows weirdness.

Thought was that this would be faster than a map, since a vector can be
updated more efficiently. It turns out to not seem to matter; runtime and
memory usage are basically identical.

Android builds tested with very close to 4.8

Mostly for the debian stable autobuilds, which have a too old version
to use the Crypto.Hash module.

This is a massive win on OSX, which doesn't have a sha256sum normally.
Only use external hash commands when the file is > 1 mb,
since cryptohash is quite close to them in speed.
SHA is still used to calculate HMACs. I don't quite understand
cryptohash's API for those.
Used the following benchmark to arrive at the 1 mb number.
1 mb file:
benchmarking sha256/internal
mean: 13.86696 ms, lb 13.83010 ms, ub 13.93453 ms, ci 0.950

found 5 outliers among 100 samples (5.0%)
4 (4.0%) high mild
1 (1.0%) high severe

When quvi is installed, git-annex addurl automatically uses it to detect
when an page is a video, and downloads the video file.
web special remote: Also support using quvi, for getting files,
or checking if files exist in the web.

Cabal does not seem to have a way to check if flag A is set and then, if
flag B is set, add a dep. Instead, it makes flag B get unset if the
dep is not available.

Or until hackage stops rejecting os(gnu), if it is indeed the right name..

yesod, or the new version of warp seem to have a bug that causes the webapp to hang.

This is a compromise. I would like to nice every thread except for the
webapp thread, but it's not practical to do so. That would need every
thread to run as a bound thread, which could add significant overhead.
And any forkIO would escape the nice level.

Will be re-releasing the last version to hackage with a .1 with this fix.

catching exceptions.
As seen in this bug report, the lifted exception handling using the StateT
monad throws away state changes when an action throws an exception.
http://git-annex.branchable.com/bugs/git_annex_fork_bombs_on_gpg_file/
.. Which can result in cached values being redundantly calculated, or other
possibly worse bugs when the annex state gets out of sync with reality.
This switches from a StateT AnnexState to a ReaderT (MVar AnnexState).
All changes to the state go via the MVar. So when an Annex action is
running inside an exception handler, and it makes some changes, they
immediately go into affect in the MVar. If it then throws an exception
(or even crashes its thread!), the state changes are still in effect.
The MonadCatchIO-transformers change is actually only incidental.
I could have kept on using lifted-base for the exception handling.
However, I'd have needed to write a new instance of MonadBaseControl
for the new monad.. and I didn't write the old instance.. I begged Bas
and he kindly sent it to me. Happily, MonadCatchIO-transformers is
able to derive a MonadCatchIO instance for my monad.
This is a deep level change. It passes the test suite! What could it break?
Well.. The most likely breakage would be to code that runs an Annex action
in an exception handler, and *wants* state changes to be thrown away.
Perhaps the state changes leaves the state inconsistent, or wrong. Since
there are relatively few places in git-annex that catch exceptions in the
Annex monad, and the AnnexState is generally just used to cache calculated
data, this is unlikely to be a problem.
Oh yeah, this change also makes Assistant.Types.ThreadedMonad a bit
redundant. It's now entirely possible to run concurrent Annex actions in
different threads, all sharing access to the same state! The ThreadedMonad
just adds some extra work on top of that, with its own MVar, and avoids
such actions possibly stepping on one-another's toes. I have not gotten
rid of it, but might try that later. Being able to run concurrent Annex
actions would simplify parts of the Assistant code.

This is enough to let the configure program build.
