Once I built the basic widget, it turned out to be rather easy to replicate
it once per scheduled activity and wire it all up to a fully working UI.
This does abuse yesod's form handling a bit, but I think it's ok.
And it would be nice to have it all ajax-y, so that saving one modified
form won't lose any modifications to other forms. But for now, a nice
simple 115 line of code implementation is a win.

However, this is not working for gcrypt repos with a mangled hostname.
Problem is that the locked down key is installed before the repo is
initialized, so git-annex-shell refuses to allow the gcrypt special remote
to do its setup.
Improved probing the remote server, so it gathers a list of the
capabilities it has. From that list, we can determine which types
of remotes are supported, and display an appropriate UI.
The new buttons for making gcrypt repos don't work yet, but the old buttons
for unencrypted git repo and encrypted rsync repo have been adapted to the
new data types and are working.

This happened because the transferrer process did not know about the new
remote. remoteFromUUID crashed, which crashed the transferrer. When it was
restarted, the new one knew about the new remote so all further files would
transfer, but the one file would temporarily not be, until transfers retried.
Fixed by making remoteFromUUID not crash, and try reloading the remote list
if it does not know about a remote.
Note that this means that remoteFromUUID does not only return Nothing anymore
when the UUID is the UUID of the local repository. So had to change some code
that dependend on that assumption.
Overridable with --user-agent option.
Not yet done for S3 or WebDAV due to limitations of libraries used --
nether allows a user-agent header to be specified.

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.)

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 adding a removable drive, it's now detected if the drive contains
a gcrypt special remote, and that's all handled nicely. This includes
fetching the git-annex branch from the gcrypt repo in order to find
out how to set up the special remote.
Note that gcrypt repos that are not git-annex special remotes are not
supported. It will attempt to detect such a gcrypt repo and refuse
to use it. (But this is hard to do any may fail; see
https://github.com/blake2-ppc/git-remote-gcrypt/issues/6)
The problem with supporting regular gcrypt repos is that we don't know
what the gcrypt.participants setting is intended to be for the repo.
So even if we can decrypt it, if we push changes to it they might not be
visible to other participants.
Anyway, encrypted sneakernet (or mailnet) is now fully possible with the
git-annex assistant! Assuming that the gpg key distribution is handled
somehow, which the assistant doesn't yet help with.

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.

I noticed that adding a removable drive repo, then trying to add the same
drive again resulted in the question about whether repos should be
combined. This was because the uuid.log was not updated. Which happened
because the new uuid did not get committed on the removable drive.
This fixes that.
This includes recovery from the ssh-agent problem that led to many reporting
http://git-annex.branchable.com/bugs/Internal_Server_Error:_Unknown_UUID/
(Including fixing up .ssh/config to set IdentitiesOnly.)
Remotes that have no known uuid are now displayed in the webapp as
"unfinished". There's a link to check their status, and if the remote
has been set annex-ignore, a retry button can be used to unset that and
try again to set up the remote.
As this bug has shown, the process of adding a ssh remote has some failure
modes that are not really ideal. It would certianly be better if, when
setting up a ssh remote it would detect if it's failed to get the UUID,
and handle that in the remote setup process, rather than waiting until
later and handling it this way.
However, that's hard to do, particularly for local pairing, since the
PairListener runs as a background thread. The best it could do is pop up an
alert if there's a problem. This solution is not much different.
Also, this solution handles cases where the user has gotten their repo into
a mess manually and let's the assistant help with cleaning it up.

A ssh remote will breifly have NoUUID when it's just being set up and
git-annex-shell has not yet been queried for the UUID. So it doesn't make
sense to display any kind of error message in this case. The UI doesn't
work when there's NoUUID, and it can even crash the ajax long polling code.
So hiding NoUUID repositories is the right thing to do.
I've tested and the automatic refresh of the repolist causes the remote
to show up as soon as a UUID is recorded, when doing local pairing, and
when adding a ssh remote.
The ssh setup first runs ssh to the real hostname, to probe if a ssh key is
needed. If one is, it generates a mangled hostname that uses a key. This
mangled hostname was being used to ssh into the server to set up the key.
But if the server already had the key set up, and it was locked down, the
setup would fail. This changes it to use the real hostname when sshing in
to set up the key, which avoids the problem.
Note that it will redundantly set up the key on the ssh server. But it's
the same key; the ssh key generation code uses the key if it already
exists.
This better handles error messages formatted for console display, by
adding a <br> after each line.
Hmm, I wonder if it'd be worth pulling in a markdown formatter, and running
the messages through it?
This is so git remotes on servers without git-annex installed can be used
to keep clients' git repos in sync.
This is a behavior change, but since annex-sync can be set to disable
syncing with a remote, I think it's acceptable.
Incidentially should work around the last problem that prevented the webapp
building on Android. (Except for a few places I need to clean up after
hand-fixing the spliced TH code.)
Looking through the git sources (documentation is unclear),
it seems commit doesn't ever trigger git-gc, mostly fetching and merging
seems to. I cannot easily override the setting in all those places, so
instead set gc.auto in git config when initializing a repository with
the assistant.
This does mean that the user cannot set gc.auto=0 and completely avoid
repacks, as the assistant does it daily. But, it only does it after there
are 100x the default number of loose objects, so this is probably not going
to be too annoying.
Pass subcommand as a regular param, which allows passing git parameters
like -c before it. This was already done in the pipeing set of functions,
but not the command running set.
The transfer queue can grow larger than 10 when queueing transfers for
files that were just received, as well as requeueing failed transfers.
I probably need to do some work to prevent that, as it could use a lot of
RAM. But for now, cap the number of displayed transfers in the webapp, to
avoid flooding the browser.
The only thing lost is ./ghci
Speed: make fast used to take 20 seconds here, when rebuilding from
touching Command/Unused.hs. With cabal, it's 29 seconds.
git annex init probes for crippled filesystems, and sets direct mode, as
well as `annex.crippledfilesystem`.
Avoid manipulating permissions of files on crippled filesystems.
That would likely cause an exception to be thrown.
Very basic support in Command.Add for cripped filesystems; avoids the lock
down entirely since doing it needs both permissions and hard links.
Will make this better soon.
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
This way, once it switches to the new repo, the user can switch back to the
old one, and its menu will allow switching to the new again.
However, if there are multiple repos, the others don't yet learn about the
new repo.
Would like to also have restart UI, but that's rather harder to do,
seems it'd need to start another copy of the webapp, and redirect the
browser to its new url, but running two assistants in the same repo at
the same time isn't good.
Now there's a Config type, that's extracted from the git config at startup.
Note that laziness means that individual config values are only looked up
and parsed on demand, and so we get implicit memoization for all of them.
So this is not only prettier and more type safe, it optimises several
places that didn't have explicit memoization before. As well as getting rid
of the ugly explicit memoization code.
Not yet done for annex.<remote>.* configuration settings.
For no apparent reason, this version removes all useful instances of
ToJavaScript, leavind behind only an instance for Aeson.Value. Argh. Pissed
off at this arbitrary breaking change, and seriously considering dropping
this library.
Maybe the spec allows it, but broadcasting self-directed presence info to
all buddies is just insane.
I had to bring back the IQ messages for self-pairing, while still using
directed presence for other pairing. Ugly.
Testing between Google Talk and prosody, the directed IQ messages
were not received. Google Talk probably only relays them between
clients using the same account.
I first tried even more directed presence, with each client JID being sent
a separate presence, but that didn't work on Google Talk, particularly
it was ignored when one client sent it to another client using the same
account.
So, presence directed at the user@host of the client to pair with. Tested
working between Google Talk and prosody (in both directions), as well
as between two clients with the same account on Google Talk, and
two clients with the same account on prosody.
Only problem with this form of directed presence is that if I also use it
for git pushes, more clients than are interested in a push's data will
receive it. So I may need some better approach, or a hybrid between
directed IQ and directed presence.
Currently have three old versions of functions that more reworking is
needed to remove: getDaemonStatusOld, modifyDaemonStatusOld_, and
modifyDaemonStatusOld
