* [SHARED] signal.h -> fdsignal.hSimon Rettberg2016-02-106-6/+6

* First steps in make signals more abstract from the underlying mechanism; ↵Simon Rettberg2016-02-055-96/+71Star
| | | | | | | | | | replace epoll with poll. We now don't assume that a signal equals a single fd (eventfd on Linux). The next step would be to create a version of signal.c that uses a pipe internally, so it can be used on other platforms, like *BSD. This is also the reason epoll was replaced with poll in uplink.c
* [SERVER] BREAKING: Get rid of pseudo case-insensitivityv2.1Simon Rettberg2016-02-018-52/+39Star
| | | | | | | | | | 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 Rettberg2016-01-1111-90/+159

* [SERVER] Performance: Optimized some functions (gprof)Simon Rettberg2015-12-174-25/+45
| | | | | | | 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 Rettberg2015-12-172-15/+18
|
* [SERVER] Cancel scanning of image dir if _shutdown is setSimon Rettberg2015-12-162-4/+8
| | | | 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 Rettberg2015-12-167-68/+143

* [SERVER] Update config exampleSimon Rettberg2015-12-151-2/+6
|
* [SERVER] Remove non-working images from list, plus refactoringSimon Rettberg2015-12-156-131/+315
| | | | | | | | | | 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] Make listen port configurableSimon Rettberg2015-12-143-3/+18

* [SERVER] Free memory on exit to get new valgrind high scoreSimon Rettberg2015-12-141-1/+4
|
* [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 Rettberg2015-12-125-28/+116

* [SERVER] Reload images in another thread when triggered by signalSimon Rettberg2015-05-123-38/+62
| | | | | | | 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.
