| | | | | | | | 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>

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>

| * write behind preserves order of fops with respect to writesRaghavendra G2009-03-121-404/+947

* | 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>

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>
