*	[SERVER] Fix rid 0 proxy lookup if local version is newer	Simon Rettberg	2020-08-14	1	-5/+15
\| \| \| \| \|	There was a logic bug that would favor a remotely looked up image rid, even if we already found a higher revision locally.
*	[SERVER] FUSE: Set name for fuse theads	Simon Rettberg	2020-07-31	1	-0/+2
\|
*	[SERVER] FUSE: Use splice with move for local reads	Simon Rettberg	2020-07-31	1	-2/+16
\| \| \| \| \| \|	Greatly improves performance when reading from the local disk cache, and additionally avoids having everything in the fs cache twice (disk view and fuse view).
*	[SERVER] FUSE: Fix arguments to fuse	Simon Rettberg	2020-07-30	2	-2/+3

\|
*	[SERVER] Add FUSE mode	Simon Rettberg	2020-07-28	11	-102/+781
\| \| \| \| \|	Still needs some cleanup and optimizations, variable naming sucks, comments, etc.

\| \| \| \|	Entries in _images array might ne NULL

\|
*	[SERVER] Know when to stop	Simon Rettberg	2020-06-10	1	-1/+1

\|
*	[SERVER] Add name param to threadpool_run	Simon Rettberg	2020-03-19	6	-7/+16
\|
*	[SERVER] Use first request in queue for RTT measurements	Simon Rettberg	2020-03-17	1	-6/+20
\| \| \| \| \| \|	This makes sure the server we're potentially switching to can at least serve the next request in the queue, making sure some progress will be made.
*	[SERVER] Make sure bgrWindowSize doesn't overwhelm uplink queue	Simon Rettberg	2020-03-17	2	-0/+6
\|
*	[SERVER] Include build type and version in RPC	Simon Rettberg	2020-03-17	2	-4/+13

\|
*	[SERVER] Check server version before setting hopCount field	Simon Rettberg	2020-03-13	1	-1/+1
\|
*	[SERVER] Check and increase hopCount when adding uplink request	Simon Rettberg	2020-03-13	1	-4/+7
\|
*	[SERVER] Rewrite uplink queue handling	Simon Rettberg	2020-03-13	8	-394/+516
\| \| \| \| \| \|	- Now uses linked lists instead of huge array - Does prefetch data on client requests - Can have multiple replication requests in-flight
*	[SERVER] Fix data type	Simon Rettberg	2020-03-09	1	-2/+2
\|
*	[SERVER] Fix: Image would be assumed complete if no uplink exists	Simon Rettberg	2020-03-06	1	-1/+1
\| \| \| \|	Severe data corruption on client. Nice.
*	[SERVER] Add printf macro for image (name:rid as %s:%d)	Simon Rettberg	2020-03-06	4	-30/+27
\|
*	[SERVER] Handle "warn unused result" cases	Simon Rettberg	2020-03-06	6	-10/+26
\|
*	[SERVER] Reload cache maps periodically for local images	Simon Rettberg	2020-03-06	3	-49/+93
\| \| \| \| \| \|	If an image is incomplete, but has no upstream server that can be used for replication, reload the cache map from disk periodically, in case some other server instance is writing to the image.
*	[SERVER] Add timer task for saving cache maps	Simon Rettberg	2020-03-04	6	-75/+164
\| \| \| \| \| \| \| \| \|	Cache maps will now be saved periodically, but only if either they have a "dirty" bit set, which happens if any bits in the map get cleared again (due to corruption), or if new data has been replicated from an uplink server. This either means at least one byte received and 5 minutes have passed, or at least 500MB have been downloaded. The timer currently runs every 20 seconds.
*	[SERVER] Likewise, get rid of same loops in client handler	Simon Rettberg	2020-03-04	2	-51/+39
\|
*	[SERVER] Get rid of two loops in image_updateCacheMap	Simon Rettberg	2020-03-03	1	-22/+18
\|
*	[SERVER] Optimize client handler for CMD_GET_BLOCK	Simon Rettberg	2020-03-03	1	-25/+43
\| \| \| \| \| \| \| \|	Move CMD_GET_BLOCK out of switch block and mark as likely. Don't acquire and release cache map for every single request, but keep reference around and only release when a message other than CMD_GET_BLOCK arrives. On idle links, this should happen through CMD_KEEPALIVE every now and then.
*	[SERVER] Expose image->problem bools as bitmask in RPC json data	Simon Rettberg	2020-03-03	2	-4/+13
\|
*	[SERVER] Also add a flag for uplink queue overload	Simon Rettberg	2020-03-03	3	-8/+16
\|
*	[SERVER] Remove "working" flag, introduce fine-grained flags	Simon Rettberg	2020-03-03	6	-158/+197
\| \| \| \| \| \| \| \|	Tracking the "working" state of images using one boolean is insufficient regarding the different ways in which providing an image can fail. Introduce separate flags for different conditions, like "file not readable", "file not writable", "no uplink server available", "file content has changed".
*	[SERVER] altservers: Fix missing index mapping (replication)	Simon Rettberg	2020-02-26	1	-1/+1
\|
*	[SERVER] Introduce ignoreAllocErrors	Simon Rettberg	2020-02-24	3	-2/+16
\| \| \| \| \|	If enabled, a failed fallocate will not abort image replication, but retry with sparse mode.
*	[SERVER] Lookup image on storage even in proxy mode	Simon Rettberg	2020-01-28	1	-8/+11
\| \| \| \| \| \| \|	In proxy mode, when rid 0 is requested, we now first query our uplink servers for the latest revision and if this fails, like in non-proxy mode, we'll see what the latest version on disk is.
