In v6 unlocked mode, this fixes a problem that was making eg,
echo > file cause the assistant to copy the file to the annex object,
instead of hard linking it. That because 2 change events were seen
(one for opening the file and one for closing) and processed together
the file was then locked down twice. Which meant it had mutiple hard links,
and so prevented linkAnnex from hard linking it.
There might be scenarios where multiple events come in, but staggered such
that a file gets locked down repeatedly, and it would still be copied to
the annex object in that case.
This can happen when ingesting a new file in either locked or unlocked
mode, when some unlocked files in the repo use the same key, and the
content was not locally available before.
There should be no behavior changes in this commit, it just adds a more
expressive data type and adjusts code that had been passing around a [UUID]
or sometimes a Maybe Remote to instead use [VerifiedCopy].
Although, since some functions were taking two different [UUID] lists,
there's some potential for me to have gotten it horribly wrong.
Also, rename lockContent to lockContentExclusive
inAnnexSafe should perhaps be eliminated, and instead use
`lockContentShared inAnnex`. However, I'm waiting on that, as there are
only 2 call sites for inAnnexSafe and it's fiddly.
It's confusing, easy to select by accident and get into a situation the
webapp offers no easy recovery from, and pausing syncing works just as well
in most situations.

yesod-core-1.4.14 changed the Template Haskell behind the expansion of
mkYesodData, such that it now must have the application data type

This works, but needs more testing and work on cases like encrypted repos,

This was a reversion caused by the relative path changes in 5.20150113.
Other uses of addAuthorizedKeys seem to be ok. If the user enters a
directory like ~/annex, it writes GIT_ANNEX_SHELL_DIRECTORY=annex, and
git-annex-shell assumes that's relative to HOME.
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.
I've tested all the dataenc to sandi conversions except Assistant.XMPP,

webapp: When adding another local repository, and combining it with the

relative path changes in 5.20150113.
Most of the time, there will be no discreprancy between programPath and
readProgramFile.
But, the programFile might have been written by an old version of git-annex
that is still installed, while a newer one is currently running. In this
case, we want to run the same one that's currently running.
This is especially important for things like the GIT_SSH=git-annex used for
ssh connection caching.
The only code that still uses readProgramFile directly is the upgrade code,
which needs to know where the standalone git-annex was installed, in order to
upgrade it.
Note that while the assistant detects changes made to remote names, I left
the commit message fixed rather than calculating it after every commit. It
doesn't seem worth the CPU to do the latter.
* init: Repository tuning parameters can now be passed when initializing a

This is necessary for interop between inode caches created on unix and
windows. Which is more important than supporting inodecaches for large keys
with the wrong size, which are broken anyway.
There should be no slowdown from this change, except on Windows.
Avoid using fileSize which maxes out at just 2 gb on Windows.
Instead, use hFileSize, which doesn't have a bounded size.
Fixes support for files > 2 gb on Windows.
Note that the InodeCache code only needs to compare a file size,
so it doesn't matter it the file size wraps. So it has been
left as-is. This was necessary both to avoid invalidating existing inode
caches, and because the code passed FileStatus around and would have become
more expensive if it called getFileSize.

The crash came from calling Git.repoLocation, but it made sense to fix this
higher up, because there is nothing to edit about the web, it just is what
it is.
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.
Based on the example from the tip, but modified to cd into the repo before

Support users who have set commit.gpgsign, by disabling gpg signatures for
git-annex branch commits and commits made by the assistant.
The thinking here is that a user sets commit.gpgsign intending the commits
that they manually initiate to be gpg signed. But not commits made in the
background, whether by a deamon or implicitly to the git-annex branch.
gpg signing those would be at best a waste of CPU and at worst would fail,
or flood the user with gpg passphrase prompts, or put their signature on
changes they did not directly do.
See Debian bug #753720.
Also makes all commits done by git-annex go through a few central control

Someone reported:
gpg: WARNING: unsafe permissions on homedir `/var/folders/m6/zkd11n111m38ff37zbtgq0lr0000gp/T/git-annex-gpg.tmp.0'
Just a warning, but let's fix it anyway. Preumably the user has one of the
many insane and delightful umasks users sometimes use to shoot themselves
in their feet.
Yes, this means that git annex webapp on windows execs git-annex, which
execs itself to set env, and the execs itself again to redirect logs.
This is disgusting. This is Windows(TM).
When in direct mode, update the master branch after committing to the
annex/direct/master branch. Also, update the synced/master branch.
This fixes a topology A->B where both A and B are in direct mode and
running the assistant, and a change is made to B. Before this fix, A pulled
the changes from B, but since they were only on the annex/direct/master
branch, it did not merge them.
Note that I considered making the assistant merge the
remotes/B/annex/direct/master, but decided to keep it simple and only merge
the sync branches as before.
On Windows, changing the time zone causes the apparent mtime of files to
change. This confuses git-annex, which natually thinks this means the files
have actually been modified (since THAT'S WHAT A MTIME IS FOR, BILL <sheesh>).
Work around this stupidity, by using the inode sentinal file to detect if
the timezone has changed, and calculate a TSDelta, which will be applied
when generating InodeCaches.
This should add no overhead at all on unix. Indeed, I sped up a few
things slightly in the refactoring.
Seems to basically work! But it has a big known problem:
If the timezone changes while the assistant (or a long-running command)
runs, it won't notice, since it only checks the inode cache once, and
so will use the old delta for all new inode caches it generates for new
files it's added. Which will result in them seeming changed the next time
it runs.

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.
This avoids a collision if different ssh ports are used on the same host
for some reason.
Note that it's ok to change the format of the mangled hostname; unmangling
only extracts the hostname from it, and once ssh is configured for a
mangled hostname, that config is not changed.

52601eb606
avoid stomping on its description, even though no description exists until
after syncing is complete
Just after enabing a ssh remote, we've not synced with it yet, so its
description and group are not known. So, avoid showing edit form so user
doesn't see blank info. Instead, redirect to dashboard.
Avoid stomping on existing group and preferred content settings
when enabling or combining with an already existing remote.
Two level fix. First, use defaultStandardGroup rather than
setStandardGroup, so if there is an existing configuration in the git-annex
branch, it's not overwritten.
To handle pre-existing ssh remotes (including gcrypt), a second level is
needed, because before syncing with the remote, it's configuration won't be
available locally. (And syncing could take a long time.) So, in this case,
keep track of whether the remote is being created or enabled, and only set
configs when creating it.

When adding a repo from a removable drive that already exists, fetch
from it before showing the edit form, so it will have the existing
configuration of that repo.
This does mean that if the webapp is asked to add a git repository on
a removable drive that already exists, but is not yet a git-annex
repository, it will avoid putting it in any group. That unlikely edge case
is ok; the next step is the edit repository screen, which will show it's
not in any group and the user can pick one.
There was a tricky bit here, when it does combine, the edit form is shown,
and so the info needs to be committed to the new repository, but then
pulled into the current one. And caches need to be invalidated for it
to be visible in the edit form.
This is the capstone in making the webapp remember ssh remotes
so they can be easily enabled in other clones of the repository.
Currently, the user will need to enter a password to enable the ssh remote,
but everything else is filled in automatically.

The repository must have been added using initremote.

Avoid any possibilty of prompting in ssh setup in webapp.
Prticularly on Windows this was a problem, it seemed to enter an infinite
loop. I think that ssh can sometimes use SSH_ASKPASS for y/n prompting,
when no controlling TTY is available, and since git-annex always answers
back with the host's password, not y/n, it looped.

When setting up a remote on a ssh server, prompt for a password inside the
webapp, rather than relying on ssh's own password prompting in the terminal
the webapp was started from, or ssh-askpass.
Avoids double prompting for the ssh password (and triple-prompting on
windows for rsync.net), since the entered password is cached for 10 minutes
and this cached password is reused when setting up the repository, after
the initial probe.
When the user has an existing ssh key set up, they can choose to use it,
rather than entering a password. The webapp used to probe for this case
automatically, so this is a little harder, but it's an advanced user thing.
Note that this commit is known to break enabling existing rsync
repositories. It hs not been tested with gcrypt repositories. It's not been

* webapp: Support using git-annex on a remote server, which was installed

Only fsck and reinject and the test suite used the Backend, and they can

This is a new feature, it was not handled before, since it's a bit of an
edge case. However, it can be handled exactly the same as a file/dir
conflict, just leave the non-annexed item alone.
While implementing this, the core resolveMerge' function got a lot simpler
and clearer. Note especially that where before there was an asymetric call to
stagefromdirectmergedir, now graftin is called symmetrically in both cases.
And, in order to add that `graftin us`, the current branch needed to be
known (if there is no current branch, there cannot be a merge conflict).
This led to some cleanups of how autoMergeFrom behaved when there is no

Trying to start in such a repo will, obviously, fail.
Note that assistant --autostart will try to start in such a repo, and fail,

This allows eg, putting .git/annex/tmp on a ram disk, if the disk IO
of temp object files is too annoying (and if you don't want to keep
partially transferred objects across reboots).
.git/annex/misctmp must be on the same filesystem as the git work tree,
since files are moved to there in a way that will not work cross-device,
as well as symlinked into there.
I first wanted to put the tmp objects in .git/annex/objects/tmp, but
that would pose transition problems on upgrade when partially transferred
objects existed.
git annex info does not currently show the size of .git/annex/misctemp,
since it should stay small. It would also be ok to make something clean it
out, periodically.
Removed instance, got it all to build using fromRef. (With a few things
that really need to show something using a ref for debugging stubbed out.)
Then added back Read instance, and made Logs.View use it for serialization.

The ctrl-c hack used before didn't actually seem to work.
No haskell libraries expose TerminateProcess. I tried just calling it via

We all know what the cake was made of.
This is no longer necessary, at least with msysgit 1.8.5.2.msysgit.0.
Its root cause may have been fixed by other recent git path fixes.
It was causing the webapp to fail to make repos on other drives.
On Windows, a file that is not writable cannot be deleted even if in a
directory with write perms. So git object files were not getting deleted
when removing a git repository.
* sync --content: Honor annex-ignore configuration.
* sync: Don't try to sync with xmpp remotes, which are only currently

Several places assumed this would not happen, and when the AssociatedFile

As part of this, preferred content checks pass the Key around.
Note that checkMatcher is sometimes now called with Just Key and Just File.
It currently constructs a FileMatcher, ignoring the Key. However, if it
constructed a FileKeyMatcher, which contained both, then it might be
possible to speed up parts of Limit, which currently call the somewhat
expensive lookupFileKey to get the Key.
I have not made this optimisation yet, because I am not sure if the key is
always the same. Will need some significant checking to satisfy myself
that's the case..
Make sanity checker run git annex unused daily, and queue up transfers
of unused files to any remotes that will have them. The transfer retrying
code works for us here, so eg when a backup disk remote is plugged in,
any transfers to it are done. Once the unused files reach a remote,
they'll be removed locally as unwanted.
If the setup does not cause unused files to go to a remote, they'll pile
up, and the sanity checker detects this using some heuristics that are
pretty good -- 1000 unused files, or 10% of disk used by unused files,
or more disk wasted by unused files than is left free. Once it detects
this, it pops up an alert in the webapp, with a button to take action.
TODO: Webapp UI to configure this, and also the ability to launch an
immediate cleanup of all unused files.

* numcopies: New command, sets global numcopies value that is seen by all
clones of a repository.
* The annex.numcopies git config setting is deprecated. Once the numcopies
command is used to set the global number of copies, any annex.numcopies
git configs will be ignored.
* assistant: Make the prefs page set the global numcopies.
This global numcopies setting is needed to let preferred content
expressions operate on numcopies.
It's also convenient, because typically if you want git-annex to preserve N
copies of files in a repo, you want it to do that no matter which repo it's
running in. Making it global avoids needing to warn the user about gotchas
involving inconsistent annex.numcopies settings.
(See changes to doc/numcopies.mdwn.)
Added a new variety of git-annex branch log file, that holds only 1 value.

Similar to the assistant, this honors any configured preferred content
expressions.
I am not entirely happpy with the implementation. It would be nicer if
the seek function returned a list of actions which included the individual
file gets and copies and drops, rather than the current list of calls to
syncContent. This would allow getting rid of the somewhat reundant display
of "sync file [ok|failed]" after the get/put display.
But, do that, withFilesInGit would need to somehow be able to construct
such a mixed action list. And it would be less efficient than the current
implementation, which is able to reuse several values between eg get and
drop.
Note that currently this does not try to satisfy numcopies when
getting/putting files (numcopies are of course checked when dropping
files!) This makes it like the assistant, and unlike get --auto
and copy --auto, which do duplicate files when numcopies is not yet
satisfied. I don't know if this is the right decision; it only seemed to
make sense to have this parallel the assistant as far as possible to start
with, since I know the assistant works.

So that remotes that use a persistent network connection are restarted.
A remote might keep open a long duration network connection, and could
fail to deal well with losing the connection. This is particularly a
concern now that we have external special reotes. An external
special remote that is implemented naively might open the connection only
when PREPARE is sent, and if it loses connection, throw errors on each
request that is made.
(Note that the ssh connection caching should not have this problem; if the
long-duration ssh process loses connection, the named pipe is disconnected
and the next ssh attempt will reconnect. Also, XMPP already deals with
disconnection robustly in its own way.)
There's no way for git-annex to know if a lost network connection actually
affects a given remote, which might have a transfer in process. It does not
make sense to force kill the transferkeys process every time the NetWatcher
detects a change. (Especially because the NetWatcher sometimes polls 1
change per hour.)
In any case, the NetWatcher only detects connection to a network, not
disconnection. So if a transfer is in progress over the network, and the
network goes down, that will need to time out on its own.
An alternate approch that was considered is to use a separate transferkeys
process for each remote, and detect when a request fails, and assume that
means that process is in a failing state and restart it. The problem with
that approach is that if a resource is not available and a remote fails
every time, it degrades to starting a new transferkeys process for every
file transfer, which is too expensive.
Instead, this commit only handles the network reconnection case, and restarts
transferkeys only once the network has reconnected and another transfer needs
to be made. So, a transferkeys process will be reused for 1 hour, or until the
next network connection.

This has not been tested at all. It compiles!
The only known missing things are support for encryption, and for get/set
of special remote configuration, and of key state. (The latter needs
separate work to add a new per-key log file to store that state.)
Only thing I don't much like is that initremote needs to be passed both
type=external and externaltype=foo. It would be better to have just
type=foo
Most of this is quite straightforward code, that largely wrote itself given
the types. The only tricky parts were:
* Need to lock the remote when using it to eg make a request, because
in theory git-annex could have multiple threads that each try to use
a remote at the same time. I don't think that git-annex ever does
that currently, but better safe than sorry.
* Rather than starting up every external special remote program when
git-annex starts, they are started only on demand, when first used.
This will avoid slowdown, especially when running fast git-annex query
commands. Once started, they keep running until git-annex stops, currently,
which may not be ideal, but it's hard to know a better time to stop them.
* Bit of a chicken and egg problem with caching the cost of the remote,
because setting annex-cost in the git config needs the remote to already
be set up. Managed to finesse that.

Batch detection is heuristic, so can sometimes fail. I observed one such
failure while starting up in a repository with 87000 files. After the first
several batches of ~5000 files, it fell out of batch mode, and never
re-entered it, and so made many more commits of a few files at a time
than necessary.
So, let's always use batch mode when in the startup scan. This avoids the
heuristic there, at least.
There is clearly also room to improve the heuristic. Possibly 10 files is
too high a bar to be found during a commit, on a system that can commit
quickly.
Fixed up a number of things that had worked around there not being a way to
get that.
Most notably, transfer info files on windows now include the process id,
since no locking is currently done. This means the file format varies
between windows and unix.
Windows has a larger (unsigned) PID space, so cannot use the unix CInt
there.
Note that TransferInfo does not yet ever get the TransferPid populated,
as there is missing locking.
transferkeys had used special FDs for communication, but that would be
quite annoying to do in Windows.
Instead, use stdin and stdout. But, to avoid commands like rsync stomping
on them and messing up the communications channel, they're duplicated to a
different handle; stdin is replaced with a null handle, and stdout is
replaced with a copy of stderr. This should all work in windows too.
Stopping in progress transfers may work on windows.. if the types unify
anyway. ;) May need some more porting.
Fixes a test case I received where a corrupted repo was repaired, but the
git-annex branch was not. The root of the problem was that the
MissingObject returned by the repair code was not necessarily a complete
set of all objects that might have been deleted during the repair.
So, stop trying to return that at all, and instead make the index file
checking code explicitly verify that each object the index uses is present.
The assistant's commit code also always avoids git commit, for simplicity.
Indirect mode sync still does a git commit -a to catch unstaged changes.
Note that this means that direct mode sync no longer runs the pre-commit
hook or any other hooks git commit might call. The git annex pre-commit
hook action for direct mode is however explicitly run. (The assistant
already ran git commit with hooks disabled, so no change there.)
This works around horribleness in the Mavericks cpp, which falls over on
the #if when configure is running. Moving it avoids the file being built at
that point.
But it's also a location that makes sense..
The Upgrader avoids checking for upgrades on startup when it was just
upgraded. This avoids an upgrade loop if something goes wrong. One example
of something going wrong would be if the upgrade info file and the
distribution file get out of sync (or the distribution file is cached in
a proxy), so it thinks it has upgraded to a new version, but has really
not.
When an automatic upgrade completes, or when the user clicks on the upgrade
button in one webapp, but also has it open in another browser window/tab,
we have a problem: The current web server is going to stop running in
minutes, but there is no way to send a redirect to the web browser to the
new url.
To solve this, used long polling, so the webapp is always listening for
urls it should redirect to. This allows globally redirecting every open
webapp. Works great! Tested with 2 web browsers with 2 tabs each.
May be useful for other purposes later too, dunno.
The overhead is 2 http requests per page load in the webapp. Due to yesod's
speed, this does not seem to noticibly delay it. Only 1 of the requests
could possibly block the page load, the other is async.
Made alerts be able to have multiple buttons, so the alerts about upgrading
can have a button that enables automatic upgrades.
Implemented automatic upgrading when the program file has changed.
Note that when an automatic upgrade happens, the webapp displays an alert
about it for a few minutes, and then closes. This still needs work.
