Joey Hess e213ef310f git-annex (5.20140717) unstable; urgency=high
* Fix minor FD leak in journal code. Closes: #754608
  * direct: Fix handling of case where a work tree subdirectory cannot
    be written to due to permissions.
  * migrate: Avoid re-checksumming when migrating from hashE to hash backend.
  * uninit: Avoid failing final removal in some direct mode repositories
    due to file modes.
  * S3: Deal with AWS ACL configurations that do not allow creating or
    checking the location of a bucket, but only reading and writing content to
    it.
  * resolvemerge: New plumbing command that runs the automatic merge conflict
    resolver.
  * Deal with change in git 2.0 that made indirect mode merge conflict
    resolution leave behind old files.
  * sync: Fix git sync with local git remotes even when they don't have an
    annex.uuid set. (The assistant already did so.)
  * Set gcrypt-publish-participants when setting up a gcrypt repository,
    to avoid unncessary passphrase prompts.
    This is a security/usability tradeoff. To avoid exposing the gpg key
    ids who can decrypt the repository, users can unset
    gcrypt-publish-participants.
  * Install nautilus hooks even when ~/.local/share/nautilus/ does not yet
    exist, since it is not automatically created for Gnome 3 users.
  * Windows: Move .vbs files out of git\bin, to avoid that being in the
    PATH, which caused some weird breakage. (Thanks, divB)
  * Windows: Fix locking issue that prevented the webapp starting
    (since 5.20140707).

Lots of progress from yesterday's modest start of building data types for
scheduling. Last night I wrote the hairy calendar code to calculate when
next to run a scheduled event. (This is actually quite superior to `cron`,
which checks every second to see if it should run each event!) Today I
built a "Cronner" thread that handles spawning threads to handle each
scheduled event. It even notices when changes have been made to the its
schedule and stops/starts event threads appropriately.
Everything is hooked up, building, and there's a good chance it works
without too many bugs, but while I've tested all the pure code (mostly
automatically with quickcheck properties), I have not run the Cronner
thread at all. And there is some tricky stuff in there, like noticing
that the machine was asleep past when it expected to wake up, and deciding
if it should still run a scheduled event, or should wait until next time.
So tomorrow we'll see..
