* libglusterfs: Replace pipe2 with pipe.Poornima G2015-03-101-1/+16
| | | | | | | | | | | | | | pipe2() doesn't works on Linux kernel version < 2.6.27 and glibc < version 2.9. Hence replacing it with pipe(), so that the build will not fail on Centos5.

| | | | | | | | | | | | | | | | | | Make sure we do not get stuck looping forever in event_dispatch_destroy() by limiting the retries when waiting for other threads, and by giving up when writing to other thread fails. This fixes regression tests hanging forever on NetBSD.

* epoll: Adding the ability to configure epoll threadsShyam2015-02-071-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to configure the number of event threads for various gluster services. Currently with the multi thread epoll patch, it is possible to have more than one thread waiting on socket activity and processing the same. This thread count is currently static, which this commit makes dynamic. The current services which use IO path, i.e brick processes, any client process (nfs, FUSE, gfapi, heal, rebalance, etc.a), gain 2 set parameters to control the number of threads that are processing events. These settings are, - client.event-threads <n> - server.event-threads <n> The client setting affects the client graph consumers, and the server setting affects the brick processes. These are processed and inited/reconfigured using the client/server protocol xlators. Other services (say glusterd) would need to extend similar configuration settings to take advantage of multi threaded event processing. At present glusterd is not enabled with this commit, as it does not stand to gain from this multi-threading (as I understand it).

* epoll: edge triggered and multi-threaded epollVijaikumar M2015-02-071-2/+16
| | | | | | | | | | | | | | | | | | | | | | | - edge triggered (oneshot) polling with epoll - pick one event to avoid multiple events getting picked up by same thread and so get better distribution of events against multiple threads - wire support for multiple poll threads to epoll_wait in parallel - evdata to store absolute index and not hint for epoll - store index and gen of slot instead of fd and index hint - perform fd close asynchronously inside event.c for multithread safety - poll is still single threaded Change-Id: I536851dda0ab224c5d5a1b130a571397c9cace8f BUG: 1104462 Signed-off-by: Anand Avati <avati@redhat.com> Signed-off-by: Vijaikumar M <vmallika@redhat.com> Signed-off-by: Jeff Darcy <jdarcy@redhat.com> Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: http://review.gluster.org/3842 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>
