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).

Got the entire webapp to build on Windows.
Compiling was easy. One line of code had to be #ifdefed out, and the whole
rest of the webapp UI just built!
Linking was epic. It seems that I really am runninginto a 32kb command line length
limit, which causes the link command to fail on Windows. git-annex with all
its bells and whistles enabled is just too big. Filed a
[ghc bug report](https://ghc.haskell.org/trac/ghc/ticket/8596), and got back a
helpful response about using <http://gcc.gnu.org/wiki/Response_Files> to
work around.
6 hours of slogging through compiling dependencies and fighting with
toolchain later, I have managed to link git-annex with the webapp!
The process is not automated yet. While I was able to automate
passing gcc a @file with its parameters, gcc then calls collect2, which
calls ld, and both are passed too many parameters. I have not found a way
to get gcc to generate a response file. So I did it manually. Urgh.
Also, it crashes on startup with `getAddrInfo` failure. But some more
porting is to be expected, now that the windows webapp links.. ;)
