*	[SERVER] Refactor uplink/cache handling, improve crc checking	Simon Rettberg	2018-07-04	1	-4/+2
\| \| \| \| \| \| \| \| \| \| \| \| \|	The cacheFd is now moved to the uplink data structure and will only be handled by the uplink thread. The integrity checker now supports checking all blocks of an image. This will be triggered automatically whenever a check for a single block failed. Also, if a crc check on startup fails, the image won't be discarded anymore, but rather a full check will be initiated. Furthermore, when calling image_updateCacheMap() on an image that was previously complete, the cache map will now be re-initialized, and a new uplink connection created.
*	[SERVER] Try to re-open cacheFd if writing fails	Simon Rettberg	2018-06-25	1	-0/+2
\| \| \| \| \| \| \|	In scenarios where the proxy is using an NFS server as storage (for whatever crazy reason) or when the cacheFd goes bad through e.g. a switchroot, try to re-open it instead of just disabling caching forever.
*	[SERVER] Make sure image has read fd before reading	Simon Rettberg	2018-06-13	1	-0/+2

*	[SERVER] Experimental support for sparse files in proxy mode	Simon Rettberg	2018-03-15	1	-0/+2
\| \| \| \| \| \| \| \| \| \| \| \|	Will not preallocate images in this mode. Old images are only deleted if the disk is full, determined by write() calls to the cache file yielding ENOSPC or EDQUOT. In such a case, the least recently used image(s) will be deleted to free up at least 256MiB, and then the write() call will be repeated. This should work somewhat reliably unless the cache partition is ridiculously small. Performance might suffer a little, and disk fragmentation might occur much faster than in prealloc mode. Testing is needed.

*	[SERVER] Implement closeUnusedFd config option	Simon Rettberg	2017-09-02	1	-0/+2
\| \| \| \| \| \| \|	This will close the readFd of images that have no active clients after some idle period (1 hour currently). Prevents deleted images from taking up space until the server is shut down.

*	[SERVER] Performance: Optimized some functions (gprof)	Simon Rettberg	2015-12-17	1	-1/+1
\| \| \| \| \| \| \|	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] Support looking on disk if an unknown image is requested	Simon Rettberg	2015-12-12	1	-1/+1
\|
*	[SERVER] Reload images in another thread when triggered by signal	Simon Rettberg	2015-05-12	1	-1/+2
\| \| \| \| \| \| \|	The server used to reload all images on the main thread, which is also responsible for accepting connections. While reloading the list, no new connections were accepted, which lead to clients marking the server as bad during their RTT measurements, then switching away from it.
