This allows using Git.Remote w/o needing to have Git.BuildVersion, which
requires configure. It will simplify github-backup when these libraries are
used there.
Found these with:
git grep "^ " $(find -type f -name \*.hs) |grep -v ': where'
Unfortunately there is some inline hamlet that cannot use tabs for
indentation.
Also, Assistant/WebApp/Bootstrap3.hs is a copy of a module and so I'm
leaving it as-is.
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

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.
avoid editing repo for same reasons as in
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.
Turned out to be much much simpler than expected, because I was able to
reuse the existing code for enabling rsync and gcrypt remotes, which
was already sufficiently general that it will also work for ssh remotes.
Total win!

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
successfully tested yet on Windows.

* webapp: Support using git-annex on a remote server, which was installed
from the standalone tarball or OSX app, and so does not have
git-annex in PATH (and may also not have git or rsync in PATH).
* standalone tarball, OSX app: Install a ~/.ssh/git-annex-wrapper, which
can be used to run git-annex, git, rsync, etc.
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
supported when using the assistant.
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.
Will probably be useful for other stuff later.

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.
The webapp will check twice a day, when the network is connected, to see if
it can download a distributon upgrade file. If a newer version is found,
display an upgrade alert.
This will need the autobuilders to set UPGRADE_LOCATION to the url
it can be downloaded from when building git-annex. Only builds with that
set need automatic upgrade alerts.
Currently, the upgrade page just requests the user manually download
and upgrade it. But, all the info is provided to do automated upgrades
in the future.
Note that urls used will need to all be https.

Complicated by such repositories potentially being repos that should have
an annex.uuid, but it failed to be gotten, perhaps due to the past ssh repo
setup bugs. This is handled now by an Upgrade Repository button.
When starting up the assistant, it'll remind about the current
repository, if it doesn't have checks. And when a removable drive
is plugged in, it will remind if a repository on it lacks checks.
Since that might be annoying, the reminders can be turned off.

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.
This commit was sponsored by Navishkar Rao.
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.
