This is needed only because of the new MonadMask needed for bracket
in the new version. Ifdefing it everywhere is not practical, since the
Setup.hs uses it.
The hoary old HTTP library was only used when checking if an url exists,
when curl was not available. It had many problems, including not supporting
https at all.
Now, this is done using http-conduit for all urls that it supports. Falls
back to curl for any url that http-conduit doesn't like (probably ftp etc,
but could also be an url that its parser chokes on for whatever reason).
This adds a new dependency on http-conduit, but webdav support already
indirectly depended on that, and the s3-aws branch also uses it.
This opens up the possibility of using http-conduit for large file
downloads, but for now I've left it using wget/curl.

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.
This speeds up the webdav special remote somewhat, since it often now
groups actions together in a single http connection when eg, storing a
file.
Legacy chunks are still supported, but have not been sped up.
This depends on a as-yet unreleased version of DAV.

This version of wai changed the type of Middleware, so I cannot seem
to liftIO inside it. So, got rid of a lot of not really needed
complexity to use System.Log.Logger's logging stuff, and just use
the standard wai stdout logger when debug logging is enabled.
Format may change some, and it logs http to stdout instead of stderr
now. Doesn't matter for the webapp since both go to the same log anyway.
Motivation: Hook scripts for nautilus or other file managers
need to provide the user with feedback that a file is being downloaded.

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.
Now can tell if a repo uses gcrypt or not, and whether it's decryptable
with the current gpg keys.
This closes the hole that undecryptable gcrypt repos could have before been
combined into the repo in encrypted mode.
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.

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.
Been meaning to do this for some time; Android port was last straw.
Note that newer versions of the uuid library have a Data.UUID.V4 that
generates random UUIDs slightly more cleanly, but Debian has an old version
of the library, so I do it slightly round-about.
This adds a dep on haskell's async library, but since that's been
added to the recent haskell platform release, it should not be
much hardship to my poor long-suffering library chasing users.
Adjust build deps to ensure that only a fixed version of the library will
be used.
Also, removed the bound thread stuff, which I now think was (probably)
a red herring.
MountWatcher can't do this, because it uses the session dbus,
and won't have access to the new DBUS_SESSION_BUS_ADDRESS if a new session
is started.
Bumped dbus library version, FD leak in it is fixed.
For now, when dbus goes away, the assistant keeps running but does not fall
back or reconnect. To do so needs more changes to the DBus library; in
particular a connectSessionWith and connectSystemWith to let me specify
my own clientThreadRunner.
At recommends it causes avahi-daemon to be pulled in on upgrade, which is
just too annoying to deal with avoiding on servers. MDNS is needed for
robust peering, but probably most desktop systems have it anyway; it's in
task-desktop.
Note that here I don't need blaze-markup for cabal to succeed, but Jimmy
reports he does. Seems like Text.Blaze.Renderer.String moved from blaze to
blaze-markup in some version.
The commit thread now has access to a channel containing the times of
all uncommitted changes. This lets it be smart about detecting busy times
when a batch job is running (such as rm -rf, or untarring something, etc),
and avoid committing until it's done. While at the same time, instantly
committing one-off changes that the user is going to expect to see
immediately.
I had to use STM to implement the channel, because of
http://hackage.haskell.org/trac/ghc/ticket/4154
While this adds a dependency, I always wanted to use STM, so this actually
makes me happy. ;)
Also happy that shouldCommit is a pure function, so other commit smartness
strategies can easily be played with. Although the current one seems pretty
good.
There is one bug, for some reason it does double commits, every time.
git-annex (but not git-annex-shell) supports the git help.autocorrect
configuration setting, doing fuzzy matching using the restricted
Damerau-Levenshtein edit distance, just as git does. This adds a build
dependency on the haskell edit-distance library.
Add tuning, docs, etc.
Not sure if status is the right place to remote size.. perhaps unused
should report the size and also warn if it sees more keys than the bloom
filter allows?
This drops the >>! and >>? with the nice low fixity. IfElse does have
undocumented >>=>>! and >>=>>? operators, but I deem that too fishy.
Anyway, using whenM and unlessM is easier; I sometimes mixed the operators
up.
* This version of git-annex only works with git 1.7.7 and newer.
The breakage with old versions is subtle, and affects
annex.numcopies .gitattributes settings, so be sure to upgrade git
to 1.7.7. (Debian package now depends on that version.)
* Don't pass absolute paths to git show-attr, as it started following
symlinks when that's done in 1.7.7. Instead, use relative paths,
which show-attr only handles 100% correctly in 1.7.7. Closes: #645046
Unfortunatly I can find no way to work with the old and new gits, as
the old had bugs that require absolute paths, while the new doesn't like
them at all. And the behavior of git show-attr in 1.7.7. is the same as
eg, git add of an absolute path to a symlink, so seems entirely
intentional and not likely to change.
This includes a generic JSONStream library built on top of Text.JSON
(somewhat hackishly).
It would be possible to stream out a single json document describing
all actions, but it's probably better for consumers if they can expect
one json document per line, so I did it that way instead.
Output from external programs used for transferring files is not
currently hidden when outputting json, which probably makes it not very
useful there. This may be dealt with if there is demand for json
output for --get or --move to be parsable.
The version, status, and find subcommands have hand-crafted output and
don't do json. The whereis subcommand needs to be modified to produce
useful json.
The test suite will not be run if it cannot be compiled.
It may be possible later to split off the quickcheck using tests into
a separate program and keep most of the tests using just hunit.
