I'm not sure if git documents it aside from 0 and 1, but any integer
can be interpreted as a bool by it. Doing the same in git-annex is good
for consistency. Also, I am planning a config that starts out as a
numeric range, but will later transition to a simple bool (hopefully),
which this interpretation supports well.
This reverts commit c142696c58.
It turns out it was not needed; 681313dfd4
fixed up the git dir, so setting cwd to it works ok.
But worst, this commit broke the test suite massively. I don't understand how.
git-annex get was failing. Very weirdly, git-annex find in a fresh
clone of an annex repo, during autoinit, was displaying a side message
-- but side messages are disabled when running find.
If .git is a gitlink file, setting cwd to it will fail, but --git-dir
will succeed. And this is the only place where it sets cwd when running
git, everywhere else already uses --git-dir.
Note that, git-annex's submodule fixup code usually converts gitlink
files to symlinks, so this wasn't usually problem. Still, worth fixing.

Except for the assistant, which I think may use them between threads?
Most of the uses of SomeException were already catching only async exceptions.
But I did find a few places that were accidentially catching them.
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 change does impact git-annex config
eg "git annex config --set annex.addunlocked on"
will store "on" and new git-annex will understand that value, while
old git-annex will error:
git-annex: bad annex.addunlocked configuration in git annex config:
Parse failure: near "on"
That seems acceptable.
Not special remote configs that are only documented as =true or =false
however. Having git-annex support other values for those would break
backwards compatability when used with old versions of git-annex. And
older versions ignore invalid special remote configs.. That would not
be a good combination.
Eg"core.bare" is the same as "core.bare = true".
Note that git treats "core.bare =" the same as "core.bare = false", so the
code had to become more complicated in order to treat the absense of a
value differently than an empty value. Ugh.
Git has an obnoxious special case in git config, a line "foo" is the same
as "foo = true". That means there is no way to examine the output of
git config and tell if it was run with --null or not, since a "foo"
in the first line could be such a boolean, or could be followed by its
value on the next line if --null were used.
So, rather than trying to do such a detection, track the style of config
at all the points where it's generated.
Rather than leaking the name of the temp file, just say the config parse
failed, and where the config was downloaded from.
Not closing the bug report because two issues were reported in the same
bug report, because the universe wants me to continually re-read old
unclosed bug reports to waste my time determining what still needs to be
done.
* annex.addunlocked can be set to an expression with the same format used by
annex.largefiles, in case you want to default to unlocking some files but
not others.
* annex.addunlocked can be configured by git-annex config.
Added a git-annex-matching-expression man page, broken out from
tips/largefiles.
A tricky consequence of this is that git-annex add --relaxed
honors annex.addunlocked, but an expression might want to know the size
or content of an url, which it's not going to download. I decided it was
better not to fail, and just dummy up some plausible data in that case.
Performance impact should be negligible. The global config is already
loaded for annex.largefiles. The expression only has to be parsed once,
and in the simple true/false case, it should not do any additional work
matching it.
Adds a dependency on filepath-bytestring, an as yet unreleased fork of
filepath that operates on RawFilePath.
Git.Repo also changed to use RawFilePath for the path to the repo.
This does eliminate some RawFilePath -> FilePath -> RawFilePath
conversions. And filepath-bytestring's </> is probably faster.
But I don't expect a major performance improvement from this.
This is mostly groundwork for making Annex.Location use RawFilePath,
which will allow for a conversion-free pipleline.
The parser and looking up config keys in the map should both be faster
due to using ByteString.
I had hoped this would speed up startup time, but any improvement to
that was too small to measure. Seems worth keeping though.
Note that the parser breaks up the ByteString, but a config map ends up
pointing to the config as read, which is retained in memory until every
value from it is no longer used. This can change memory usage
patterns marginally, but won't affect git-annex.
* git-lfs: The url provided to initremote/enableremote will now be
stored in the git-annex branch, allowing enableremote to be used without
an url. initremote --sameas can be used to add additional urls.
* git-lfs: When there's a git remote with an url that's known to be
used for git-lfs, automatically enable the special remote.
This does not change the overall license of the git-annex program, which
was already AGPL due to a number of sources files being AGPL already.
Legally speaking, I'm adding a new license under which these files are
now available; I already released their current contents under the GPL
license. Now they're dual licensed GPL and AGPL. However, I intend
for all my future changes to these files to only be released under the
AGPL license, and I won't be tracking the dual licensing status, so I'm
simply changing the license statement to say it's AGPL.
(In some cases, others wrote parts of the code of a file and released it
under the GPL; but in all cases I have contributed a significant portion
of the code in each file and it's that code that is getting the AGPL
license; the GPL license of other contributors allows combining with
AGPL code.)
And for tab completion, by not unnessessarily statting paths to remotes,
which used to cause eg, spin-up of removable drives.
Got rid of the remotes member of Git.Repo. This was a bit painful.
Remote.Git modifies the list of remotes as it reads their configs,
so still need a persistent list of remotes. So, put it in as
Annex.gitremotes. It's only populated by getGitRemotes, so commands
like examinekey that don't care about remotes won't do so.

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.

Seems to work, but still experimental until it's been tested more.
When repositories are on filesystems not supporting symlinks, the .git dir
symlink trick cannot be used. Since we're going to be in direct mode
anyway, the .git dir symlink is not strictly needed.
However, I have not fixed the code that creates new annex symlinks to
handle this case -- the committed symlinks will be wrong.
git annex sync happens to currently fail in a submodule using direct mode,
because there's no HEAD ref. That also needs to be dealt with to get
this fully working in crippled filesystems.
Leaving http://github.com/datalad/datalad/issues/44 open until these issues
are dealt with.
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.
gcrypt needs to be able to fast-forward the master branch. If a git
repository is set up with git init --shared --bare, it gets that set, and
pushing to it will then fail, even when it's up-to-date.
This pulls off quite a nice trick: When given a path on rsync.net, it
determines if it is an encrypted git repository that the user has
the key to decrypt, and merges with it. This is works even when
the local repository had no idea that the gcrypt remote exists!
(As previously done with local drives.)

New setting, can be used to disable autocommit of changed files by the
assistant, while it still does data syncing and other tasks.
Also wired into webapp UI
Now that this is handled correctly, git-annex can be used in git submodules.
Also, fixed infelicity where Git.CurrentRepo and Git.Config.updateLocation
were both dealing with core.worktree. Now updateLocation handles it for
Local as well as for LocalUnknown repos.
Make Utility.Process wrap the parts of System.Process that I use,
and add debug logging to them.
Also wrote some higher-level code that allows running an action
with handles to a processes stdin or stdout (or both), and checking
its exit status, all in a single function call.
As a bonus, the debug logging now indicates whether the process
is being run to read from it, feed it data, chat with it (writing and
reading), or just call it for its side effect.
Test suite now passes with -threaded!
I traced back all the hangs with -threaded to System.Cmd.Utils. It seems
it's just crappy/unsafe/outdated, and should not be used. System.Process
seems to be the cool new thing, so converted all the code to use it
instead.
In the process, --debug stopped printing commands it runs. I may try to
bring that back later.
Note that even SafeSystem was switched to use System.Process. Since that
was a modified version of code from System.Cmd.Utils, it needed to be
converted too. I also got rid of nearly all calls to forkProcess,
and all calls to executeFile, which I'm also doubtful about working
well with -threaded.
Accept arbitrarily encoded repository filepaths etc when reading git config
output. This fixes support for remotes with unusual characters in their
names.
For example, a remote with a url of /tmp/çüş was previously
skipped, because the filename wasn't encoded right so it didn't think it
was available. And when setting the annex-uuid of a remote named "çüş",
it used to add it under a mis-encoded form of the remote's name. Both these
cases now work ok in my testing.
Avoid more expensive code path when no core.worktree is configured.
Don't change worktree when reading config if one is already set.
This could happen if GIT_CORE_WORKTREE is set, and the repo also has
core.worktree, and the config is reread. Now GIT_CORE_WORKTREE will
prevail.
