* [SERVER] BREAKING: Get rid of pseudo case-insensitivityv2.1Simon Rettberg2016-02-011-3/+3
| | | | | | | | | | This was a wrong decision made long time ago, and it's broken in certain scenarios (eg. two servers serving from same NFS mount). Also it's of limited use anyways since it only supportes ASCII and would ignore umlauts, so blöd and BLÖD would still be considered two different images. So if you relied on this "feature" in any way, be careful when updating.

* [SERVER] Performance: Optimized some functions (gprof)Simon Rettberg2015-12-171-6/+9
| | | | | | | A run with gprof revealed that background replication is a huge CPU hog. The block selection was very slow and has been improved a lot. Minor improvements were made to other functions that scan the cache map of an image and are thus relatively slow.
* [SERVER] More fine grained locking for RPC; better error loggingSimon Rettberg2015-12-161-4/+8

* [SERVER] Remove non-working images from list, plus refactoringSimon Rettberg2015-12-151-0/+6
| | | | | | | | | | Now that we can automatically load unknown images from disk on request, it makes sense to remove non-working images from the image list. On future requests, we will look for them on disk again, which is nice in case of temporary storage hickups. Also, some more ore less related locking has been refined (loading images, replicating images)
