They normally shutdown when the GNUPGHOME directory is deleted, but on
NFS they keep the directory from being deleted. And also, this avoids
a number of them piling up while the test suite is running.
This handles all createProcessSuccess callers, and aside from process
pools, the complete conversion of all process running to async exception
safety should be complete now.
Also, was able to remove from Utility.Process the old API that I now
know was not a good idea. And proof it was bad: The code size went *down*,
despite there being a fair bit of boilerplate for some future API to
reduce.
This handles all sites where checkSuccessProcess/ignoreFailureProcess
is used, except for one: Git.Command.pipeReadLazy
That one will be significantly more work to convert to bracketing.
(Also skipped Command.Assistant.autoStart, but it does not need to
shut down the processes it started on exception because they are
git-annex assistant daemons..)
forceSuccessProcess is done, except for createProcessSuccess.
All call sites of createProcessSuccess will need to be converted
to bracketing.
(process pools still todo also)
Due to eg, too long a path to the agent socket, caused by running gpg in a
container where /run is not mounted, and/or some other gpg behavior like
unnecessarily making relative paths to its home directory absolute.
Eliminated some dead code. In other cases, exported a currently unused
function, since it was a logical part of the API.
Of course this improves the API documentation. It may also sometimes
let ghc optimize code better, since it can know a function is internal
to a module.
364 modules still to go, according to
git grep -E 'module [A-Za-z.]+ where'
The gitAnnexTmpOtherDir cleanup made it be deleted too early sometimes,
and so the test suite failed. Also there was a report of a similar
failure which likely had a similar cause and hopwfully this fixes that
too.
Deleting directories is one of the great unsolved problems of CS, thanks to
abominations like NFS lock files and Windows and races with other processes
cleaning up after themselves in the background. The gpg test harness
sometimes failed to delete its temp directory on NFS. Avoid the problem
class by not deleting it at all, and putting it inside the tmp repo being
tested. The test suite's more robust (and/or nonsensical) workarounds for
deleting its test dir will thus be used, hopefully avoiding the problem
until an OS finds a new way to violate POSIX and the laws of nature.
Note that this means that the .gnupg directory will be on whatever
filesystem the test suite is being run on, which may be a lesser quality
filesystem than gpg is really expecting. Gpg does not seem to need to
write sockets etc to there so this seems ok. The only known problem is
that if the filesystem forces a directory mode like 777, gpg will warn
about unsafe home directory perms, but it still works.
Fourth or fifth try at this and finally found a way to make it work.
Absurd amount of busy-work forced on me by change in cabal's behavior.
Split up Utility modules that need posix stuff out of ones used by
Setup. Various other hacks around inability for Setup to use anything
that ifdefs a use of unix.
Probably lost a full day of my life to this.
This is how build systems make their users hate them. Just saying.
This reverts commit 51228c2306.
No, still doesn't work when built with cabal. It did with stack; stack
must somehow make the unix package implicitly available.
With cabal, System.Posix.Process and System.Posix.Env are both missing.
Seems I had all the work in past commits to make this build, at least on
linux. I'm actually surprised it does, without a unix dep, Utility.Env
still builds ok somehow despite using System.Posix.Env.

This avoids warnings from stack about the module not being listed in the
cabal file. So, the generated file is also renamed to Build/SysConfig.
Note that the setup program seems to be cached despite these changes; I
had to cabal clean to get cabal to update it so that Build/SysConfig was
written.

initremote, enableremote: Really support gpg subkeys suffixed with an
exclamation mark, which forces gpg to use a specific subkey. (Previous try
had a bug.)

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.

QuickCheck 2.10 found a counterexample eg "\929184" broke the property.
As far as I can tell, Git.Filename is matching how git handles encoding
of strange high unicode characters in filenames for display. Git does
not display high unicode characters, and instead displays the C-style
escaped form of each byte. This is ambiguous, but since git is not
unicode aware, it doesn't need to roundtrip parse it.
So, making Git.FileName's roundtrip test only chars < 256 seems fine.
Utility.Format.format uses encode_c, in order to mimic git, so that's
ok.
Utility.Format.gen uses decode_c, but only so that stuff like "\n"
in the format string is handled. If the format string contains C-style
octal escapes, they will be converted to ascii characters, and not
combined into unicode characters, but that should not be a problem.
If the user wants unicode characters, they can include them in the
format string, without escaping them.
Finally, decode_c is used by Utility.Gpg.secretKeys, because gpg
--with-colons hex-escapes some characters in particular ':' and '\\'.
gpg passes unicode through, so this use of decode_c is not a problem.

Removed dependency on MissingH, instead depending on the split
library.
After laying groundwork for this since 2015, it
was mostly straightforward. Added Utility.Tuple and
Utility.Split. Eyeballed System.Path.WildMatch while implementing
the same thing.
Since MissingH's progress meter display was being used, I re-implemented
my own. Bonus: Now progress is displayed for transfers of files of
unknown size.

The COPYRIGHT had Utility/DirWatcher* listed as GPL, but they were
actually BSD licensed.
No idea why I put the GPL on Utility/GPG.hs file originally.
I wrote all of it, except for guilhem's small changes to it in
00fc21bfec, which seem too small to be
independently copyrightable. I'm relicencing it BSD.
Turns out that Data.List.Utils.split is slow and makes a lot of
allocations. Here's a much simpler single character splitter that behaves
the same (even in wacky corner cases) while running in half the time and
75% the allocations.
As well as being an optimisation, this helps move toward eliminating use of
missingh.
(Data.List.Split.splitOn is nearly as slow as Data.List.Utils.split and
allocates even more.)
I have not benchmarked the effect on git-annex, but would not be surprised
to see some parsing of eg, large streams from git commands run twice as
fast, and possibly in less memory.

ghc 8 added backtraces on uncaught errors. This is great, but git-annex was
using error in many places for a error message targeted at the user, in
some known problem case. A backtrace only confuses such a message, so omit it.
Notably, commands like git annex drop that failed due to eg, numcopies,
used to use error, so had a backtrace.

gpg-agent started deleting its socket file on shutdown, and this tickled an
ugly behavior in removeDirectoryRecursive,
https://github.com/haskell/directory/issues/60
Running removeDirectoryRecursive again on exception avoids the problem.
gpg 2.1.15 (or so) seems to have added some new fields to the --with-colons
--list-secret-keys output. These include "fpr" and "grp", and come before
the "uid" line. So, the parser was giving up before it saw the name. Fix by
continuing to look for the uid line until the next "sec" line.

When gpg.program is configured, it's used to get the command to run for
gpg. Useful on systems that have only a gpg2 command or want to use it
instead of the gpg command.
This removes a bit of complexity, and should make things faster
(avoids tokenizing Params string), and probably involve less garbage
collection.
In a few places, it was useful to use Params to avoid needing a list,
but that is easily avoided.
Problems noticed while doing this conversion:
* Some uses of Params "oneword" which was entirely unnecessary
overhead.
* A few places that built up a list of parameters with ++
and then used Params to split it!
Test suite passes.
Didn't know that this library existed!
This includes making git-annex not re-exec itself on start on windows, and
making the test suite on Windows run tests without forking.
This fixes all instances of " \t" in the code base. Most common case
seems to be after a "where" line; probably vim copied the two space layout
of that line.
Done as a background task while listening to episode 2 of the Type Theory
podcast.
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.
Some remotes like External need to run store and retrieve actions in Annex,
not IO. In order to do that lift, I had to dive pretty deep into the
utilities, making Utility.Gpg and Utility.Tmp be partly converted to using
MonadIO, and Control.Monad.Catch for exception handling.
There should be no behavior changes in this commit.

I forgot I had <$$> hidden away in Utility.Applicative.
It allows doing the same kind of currying as does >=*>
and I found using it made the code more readable for me.
(*>=> was not used)
Now the webapp can generate a gpg key that is dedicated for use by
git-annex. Since the key is single use, much of the complexity of
generating gpg keys is avoided.
Note that the key has no password, because gpg-agent is not available
everywhere the assistant is installed. This is not a big security problem
because the key is going to live on the same disk as the git annex
repository, so an attacker with access to it can look directly in the
repository to see the same files that get stored in the encrypted
repository on the removable drive.
There is no provision yet for backing up keys.

Note that Utility.Format.prop_idempotent_deencode does not hold
now that hex escaped characters are supported. quickcheck fails to notice
this, so I have left it as-is for now.
