* fixes crash in write-behind2.0.0rc6Amar Tumballi2009-03-221-2/+3
| | | | | | | in wb_flush, there was a chance that wb_process_queue() was called with NULL frame, which causes crash. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* when the both channels in client protocol is disconnected, fd's are marked ↵Amar Tumballi2009-03-211-35/+64
| | | | | | | | | as bad patch solves the problem of fds being valid even in the case of server disconnection, which causes operations on wrong fd when server comes back up. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* fixes issue of hashing to wrong subvolumes in case when a subvolume is downAmar Tumballi2009-03-211-2/+2
| | | | | | | When a hashed subvolume is down, variable 'subvol' was NULL, but was sent to itransform. This patch solves this, and readdir is sent to proper subvolume now. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* Add return after STACK_UNWINDShehjar Tikoo2009-03-181-0/+2
| | | | | | | | We must add a 'return' after a STACK_UNWIND due to a stub creation failure, because if we dont, we'll end up adding a NULL stub to the worker thread request queue. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* Moving few translators which are not well tested, are in beta stage to ↵Amar Tumballi2009-03-187-7/+7
| | | | | | | | | | | | | 'testing/' directory. This way, users will be aware which are in 'beta' stage, and we can keep on adding new translators (if any) seemlessly to stable codebase and once tested can move them to proper places. To use these translators, everyone will have to prefix 'testing/' to existing type of translator (in volumefile) Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* ib-verbs recv-size and send-size argument takes SIZET arguments now.Amar Tumballi2009-03-182-11/+31
| | | | | | | With this patch, to specify recv-size and send-size of ib-verbs to <n>KB, we need not give the option as integer value of 'n * 1024' value. This is neater to do deployments. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

| * write behind preserves order of fops with respect to writesRaghavendra G2009-03-121-404/+947
| | | | | | | | | | | | | | - the execution order of fops like read, stat, fsync, truncate etc whose results are affected by writes, are preserved. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* | IO-threads Cleanup: Clean-up request scheduling and queueing interface.Shehjar Tikoo2009-03-171-216/+61
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch does two things: 1. Cleans up the request scheduling and queueing interface so that all fops only need to call iot_schedule and not iot_queue and in some cases iot_schedule. 2. Till now, we've had open and create calls go through the main glusterfsd thread when sending open and create fops. This patch makes them also go through the worker threads. But since the open and creates requests would not be called with a valid inode number in the loc_t, these requests will get assigned to the worker at index 0. This will be fixed RSN, when we introduce various techniques of distributing the inodes(..not requests..) over the worker threads. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* | IO-threads Cleanup: Change workers list to dynamically allocated arrayShehjar Tikoo2009-03-172-28/+51
| | | | | | | | | | | | | | | | | | | | Worker threads were represented as a list in iot_conf_t which made us traverse the list of workers in order to decide which thread gets the request. Now we represent the workers as a dynamically allocated array so that we can just index into the array to schedule the file. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* | IO-threads Cleanup: Change request queue into a struct list_headShehjar Tikoo2009-03-172-24/+20
| | | | | | | | | | | | | | | | This patch changes the per-thread request queue from a custom circular linked list, into the standard list.h list which is easier to understand and has a cleaner interface. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
* | Add system call abstraction layerVikas Gorur2009-03-176-45/+663

* feature to span the export directory across different mountpointsAmar Tumballi2009-03-102-9/+80
| | | | | | | | | This feature enables exported directory containing different mountpoints. With, 'option span-devices <n>' where n is number of different mountpoints export directories can have, one can enable this feature. By default the number will be 1, and the inode scaling won't come into picture. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
