Several bug fixes today and got caught up on most recent messages. Backlog is 157.
The most significant one prevents git-annex from reading in the whole
content of a large git object when it wants to check if it's an annex
symlink. In several situations where large files were committed to git, or
staged, git-annex could do a lot of work, and use a lot of memory and maybe
crash. Fixed by checking the size of an object before asking
git cat-file for its content.
Also a couple of improvements around versions and upgrading. IIRC git-annex used to only support one repository version at a time, but this was changed to support V6 as an optional upgrade from V5, and so the supported versions became a list. Since V3 repositories are identical to V5 other than the version, I added it to the supported version list, and any V3 repos out there can be used without upgading. Particularly useful if they're on read-only media.
And, there was a bug in the automatic upgrading of a remote that caused it to be upgraded all the way to V6. Now it will only be upgraded to V5.
