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).

### Please describe the problem.
The assistant regulary ends up trying to perform repair (I don't know why, it happens fairly often, once a week or so). When it does so, it ends up creating a huge (2.4G) .git/objects directory, and a git prune-packed process uses so much I/O the machine really slows down.
### What steps will reproduce the problem?
I don't have any reliable way to reproduce it. The repository ends up being attempted to be repaired around once a week. This week the repair (and the slowdown) also happened on a second computer.
### What version of git-annex are you using? On what operating system?
git-annex version: 5.20140221-gbdfc8e1 (using the standalone 64bit builds)
This is on an up-to-date Arch Linux. It also happened on Fedora 20.
### Please provide any additional information below.
The daemon.log is fairly long, but not particulary interesting: [[https://ssl.zerodogg.org/~zerodogg/private/tmp/daemon.log-2014-02-25.1]]
The «resource vanished (Broken pipe)» at the end is the result of me killing the prune-packed in order to be able to use the machine again.
