Offline today due to weather, but there's lots of nice backlog to work on...
I've written down a external remote querying transition plan. If you maintain an external special remote that implements WHEREIS or GETINFO, please take a look as your code would need to be updated if this is done.
Ilya suggested making git annex testremote
be able to test readonly
remotes, and I implemented that.
There was a discussion in the forum about .git/annex/misctmp/ containing cruft left by an interrupted git-annex process. I was surprised to find half a gigabyte of old files on my own laptop due to this problem. I've put in a fix, so git-annex will clean up such temp files that were left behind by a previous interrupted git-annex process.
