Needs ghc 7.6.1, so minimum base version increased slightly. All builds
are well above this version of ghc, and debian oldstable is as well.
Code that could use lambdacase can be found by running:
git grep -B 1 'case ' | less
and searching in less for "<-"

They need unix on non-windows, for Utility.Env, which Build.Configure uses,
but cabal can't express that in a custom-setup stanza.
To avoid this problem, Utility.Env would need to be moved into
unix-compat..
Windows needs the setenv package in custom-setup, but I don't want to
pull it in on unix, which would probably break some builds and need more
work. Instead, split out setEnv to a separate module.
Quite likely, unix-compat will get a portable environment layer, and
then both modules can be removed from here.

Now that windows is using unix-compat 0.5, don't need a dep on Win32
or unix in custom-setup, so the stanza can be parsed by cabal's limited
parser again.
Note that unix-compat 0.5 is needed on windows, but the cabal file
hasn't bumped it yet, since that would necessarily affect non-windows
builds. Instead, the stack-windows.yaml makes sure the right version is
pulled in.

That version has my patches for the problems that Utility.PosixFiles
was working around, so am able to get rid of that module now.
This will later allow bringing back the custom-setup stanza in the cabal
file. It will need to depend on unix-compat 0.5 on all OS's, which I'm
not ready to do yet.

Get ugly reversion out of CHANGELOG.
Also, relocated the windows stack.yaml to top, and updated windows build
instructions.

This reverts commit 839ec7e26c.
Neither way is working.. The other way failed:
.stack-work\dist\5f9bc736\build\git-annex\git-annex-tmp\Assistant.o:fake:(.text+0x6bb3): undefined reference to `terminatepid'
Seems that winprocess.c is not getting linked in.
Building with stack, it failed:
`_TerminateProcess' referenced in section `.text' of .stack-work\dist\5f9bc736\build\git-annex\git-annex-tmp\Utility\WinProcess.o: defined in discarded section `.text' of C:/Users/jenkins/AppData/Local/Programs/stack/i386-windows/ghc-8.0.2/mingw/bin/../lib/gcc/i686-w64-mingw32/5.2.0/../../../../i686-w64-mingw32/lib/../lib/libkernel32.a(dacgs01154.o)
This is a reversion of 86e638567a,
to try the other way to implement it, which will hopefully avoid the problem.
This needs to include unix except on windows, but when I tried
an if (! os(windows)) cabal crashed:
'parseField' called on a non-field. This is possibly a bug in Cabal.
Cabal is able to configure w/o the custom-setup stanza, so omit it.
This reverts commit ffa81d2d7f.
Old win32-extras fails to install. I suspect toolchain breakage because
a lot of stuff is failing on the windows autobuilder.
This is similar to the pusher thread, but a separate thread because git
pushes can be done in parallel with exports, and updating a big export
should not prevent other git pushes going out in the meantime.
The exportThread only runs at most every 30 seconds, since updating an
export is more expensive than pushing. This may need to be tuned.
Added a separate channel for export commits; the committer records a
commit in that channel.
Also, reconnectRemotes records a dummy commit, to make the exporter
thread wake up and make sure all exports are up-to-date. So,
connecting a drive with a directory special remote export will
immediately update it, and getting online will automatically
update S3 and WebDAV exports.
The transfer queue is not involved in exports. Instead, failed
exports are retried much like failed pushes.

New table needed to look up what filenames are used in the currently
exported tree, for reasons explained in export.mdwn.
Also, added smart constructors for ExportLocation and ExportDirectory to
make sure they contain filepaths with the right direction slashes.
And some code refactoring.

Went with a separate db per export remote, rather than a single export
database. Mostly because there will probably not be a lot of separate
export remotes, and it might be convenient to be able to delete a given
remote's export database.

This will allow disabling exports for remotes that are not configured to
allow them. Also, exportSupported will be useful for the external
special remote to probe.

This means that when a module is conditionally imported via ifdef
depending on the OS or build flags, the cabal file has to mirror the
same logic there to only list the module then.
Since there are lots of OS's and lots of combinations of build flags
here, it's rather difficult to know if the cabal file has been completelty
correctly updated to match the source code.
So I am very unhappy with needing to update things in two places. I've
only tested this on linux with most build flags enables; this will
probably need significant time and testing to catch every cabal file
tweak that this change to Cabal requires. And it will be a continual
source of compile failures going forward when the code is modified and
the cabal file not also updated.
DRY DRY DRY, I repeat myself, but: DRY! Sigh..
(Also, had to remove all Build.* that are standalone programs from the
Other-Modules list, because since cabal passes those modules to ghc when
building git-annex, it complains that they use module Main. Those
modules are only used when building with the Makefile anyway, so this
change shouldn't break anything.)

Security fix: Disallow hostname starting with a dash, which would get
passed to ssh and be treated an option. This could be used by an attacker
who provides a crafted ssh url (for eg a git remote) to execute arbitrary
code via ssh -oProxyCommand.
No CVE has yet been assigned for this hole.
The same class of security hole recently affected git itself,
CVE-2017-1000117.
Method: Identified all places where ssh is run, by git grep '"ssh"'
Converted them all to use a SshHost, if they did not already, for
specifying the hostname.
SshHost was made a data type with a smart constructor, which rejects
hostnames starting with '-'.
Note that git-annex already contains extensive use of Utility.SafeCommand,
which fixes a similar class of problem where a filename starting with a
dash gets passed to a program which treats it as an option.

Added remote configuration settings annex-ignore-command and
annex-sync-command, which are dynamic equivilants of the annex-ignore
and annex-sync configurations.
For this I needed a new DynamicConfig infrastructure. Its implementation
should be as fast as before when there is no dynamic config, and it caches
so shell commands are only run once.
Note that annex-ignore-command exits nonzero when the remote should be ignored.
While that may seem backwards, it allows using the same command for it as
for annex-sync-command when you want to disable both.

Can be used to override the default timestamps used in log files in the
git-annex branch. This is a dangerous environment variable; use with
caution.
Note that this only affects writing to the logs on the git-annex branch.
It is not used for metadata in git commits (other env vars can be set for
that).
There are many other places where timestamps are still used, that don't
get committed to git, but do touch disk. Including regular timestamps
of files, and timestamps embedded in some files in .git/annex/, including
the last fsck timestamp and timestamps in transfer log files.
A good way to find such things in git-annex is to get for getPOSIXTime and
getCurrentTime, although some of the results are of course false positives
that never hit disk (unless git-annex gets swapped out..)
So this commit does NOT necessarily make git-annex comply with some HIPPA
privacy regulations; it's up to the user to determine if they can use it in
a way compliant with such regulations.
Benchmarking: It takes 0.00114 milliseconds to call getEnv
"GIT_ANNEX_VECTOR_CLOCK" when that env var is not set. So, 100 thousand log
files can be written with an added overhead of only 0.114 seconds. That
should be by far swamped by the actual overhead of writing the log files
and making the commit containing them.
