fixes issue of hashing to wrong subvolumes in case when a subvolume is down

2009-03-20T22:35:52+00:00

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.

Add return after STACK_UNWIND

2009-03-18T05:37:07+00:00

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.

Moving few translators which are not well tested, are in beta stage to 'testing/' directory.

2009-03-18T02:56:29+00:00

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)

IO-threads Cleanup: Clean-up request scheduling and queueing interface.

2009-03-17T11:47:53+00:00

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.
