* [SERVER] Fix int overflows on 32bit builds in CRC generationSimon Rettberg2018-03-161-6/+6

* [SERVER] Make sparse file mode actually workSimon Rettberg2018-03-161-5/+12
|
* [SERVER] Experimental support for sparse files in proxy modeSimon Rettberg2018-03-151-10/+34
| | | | | | | | | | | | 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] Use multiConnect() to find uplink for replicationSimon Rettberg2017-11-071-12/+37
| | | | | Just as in the fuse client, this will speed things up if we have several alt-servers in our list which are not reachable.
* [SERVER] Support finer control over replication when a proxy connects to a proxySimon Rettberg2017-11-021-1/+1
| | | | | | | Introduce new flag in "select image" message to tell the uplink server whether we have background replication enabled or not. Also reject a connecting proxy if the connecting proxy uses BGR but we don't, as this would basically force the image to be replicated locally too.
* [*] Mark logadd() as printf-style function, fix errors that it revealedSimon Rettberg2017-10-311-1/+1
| | | | ...there were quite a few format string errors as it turns out :/

* [SERVER] Get rid of zlib dependencySimon Rettberg2017-10-241-16/+16
| | | | | | We only used it for CRC-32, so now the source tree includes a stripped down version of the crc32 code from the zlib project.

* [*] Support hop-counting in request header, protocol version 3Simon Rettberg2017-10-171-3/+3
| | | | | | | | | | | | | | We steal 8 bits from the request offset to count hops when requests get relayed by proxies. This still leaves plenty of bits for the offset (56 bits, supporting images of up to 72 petabytes). This is used to detect proxy cycles. The algorithm is not perfect but should prevent endless relays of the same request. This is backwards compatible to old clients and servers, as the server only ever sets the hopcount in relayed requests if the upstream server is using protocol version 3 or newer, and clients are automatically upwards compatible as there is practically no image larger than 74PB, so the newly introduced hop count field is always 0 even in requests from old clients.

* [SERVER] Implement closeUnusedFd config optionSimon Rettberg2017-09-021-0/+26
| | | | | | | 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] BREAKING: Get rid of pseudo case-insensitivityv2.1Simon Rettberg2016-02-011-17/+13Star
| | | | | | | | | | 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] Fix a lot of (mostly harmless) data racesSimon Rettberg2016-01-111-33/+46

* [SERVER] Performance: Optimized some functions (gprof)Simon Rettberg2015-12-171-7/+18
| | | | | | | 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] image_markComplete now handles locking so we remove() unlockedSimon Rettberg2015-12-171-7/+12
|
* [SERVER] Cancel scanning of image dir if _shutdown is setSimon Rettberg2015-12-161-2/+4
| | | | So you can cancel image loading on startup via Ctrl-C
* [SERVER] Fix image_calcBlockCrc32: Use 64bit for fileSize paramSimon Rettberg2015-12-161-22/+27
| | | | Using uint32_t for fileSize is not too clever :(
* [SERVER] More fine grained locking for RPC; better error loggingSimon Rettberg2015-12-161-13/+34

* [SERVER] Update config exampleSimon Rettberg2015-12-151-2/+6
|
* [SERVER] Remove non-working images from list, plus refactoringSimon Rettberg2015-12-151-51/+175
| | | | | | | | | | 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)
* [SERVER] Disallow images starting with "." now that we allow load-on-demandSimon Rettberg2015-12-141-1/+2
| | | | | This will prevent hidden files from being exported to clients and also prevents directory traversal attacks ( ../../image.img )
* [SERVER] Support looking on disk if an unknown image is requestedSimon Rettberg2015-12-121-21/+108

* [SERVER] Reload images in another thread when triggered by signalSimon Rettberg2015-05-121-31/+48
| | | | | | | 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.
