* fix some mixed space+tab indentationGravatar Joey Hess2014-10-09
| | | | | | | | | 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.
* unify exception handling into Utility.ExceptionGravatar Joey Hess2014-08-07
| | | | | | | | | | | | | | | | | | | | 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.

* sync, assistant, remotedaemon: Use ssh connection caching for git pushes and ↵Gravatar Joey Hess2014-04-12
| | | | | | | | | | | | | | | | | pulls. For sync, saves 1 ssh connection per remote. For remotedaemon, the same ssh connection that is already open to run git-annex-shell notifychanges is reused to pull from the remote. Only potential problem is that this also enables connection caching when the assistant syncs with a ssh remote. Including the sync it does when a network connection has just come up. In that case, cached ssh connections are likely to be stale, and so using them would hang. Until I'm sure such problems have been dealt with, this commit needs to stay on the remotecontrol branch, and not be merged to master. This commit was sponsored by Alexandre Dupas.
* make git-remote-daemon ssh transport robustGravatar Joey Hess2014-04-09
| | | | | | | | | | | | | | | | | | | * Remote system might be available, and connection get lost. Should reconnect, but needs to avoid bad behavior (ie, constant reconnect attempts.) Use exponential backoff. * Detect if old system had a too old git-annex-shell, and show the user a nice message in the webapp. Required parsing error messages, so perhaps this code shoudl be removed once enough time has passed.. * Switch the protocol to using remote URI's, rather than remote names. Names change. Also avoids issues with serialization of names containing whitespace. This is nearly ready for merge into master now. I'd still like to make the ssh transport smarter about reusing ssh connection caching during git pull. This commit was sponsored by Jim Paris.

* added git-annex remotedaemonGravatar Joey Hess2014-04-06
So far, handling connecting to git-annex-shell notifychanges, and pulling immediately when a change is pushed to a remote. A little bit buggy (crashes after the first pull), but it already works! This commit was sponsored by Mark Sheppard.
