786142ce73 Add a bit of statistics tracking for two reasons, a) to help inform
where a request should be enqueded and b) to track request latency.

f1cb6f8c61 Remove support for bzip2. Change build_deps.sh to only remove the
build files from wiredtiger when cleaning rather than all the files.

eafee02865 Only start 2 * num_queues worker threads initially. num_queues is generally
equal to the number of cores reported by Erlang (info.scheduler_threads) which
is either determined automatically by the Erlang BEAM runtime or via the +S
flag.  The minimum num_queues is 2, so the minimum number of workers is 4.  The
maximum number of workers is ASYNC_NIF_MAX_WORKER_QUEUE_SIZE (currently set to
128), but that would only happen if there were 64 cores (or you set +S 64:64 at
startup).

422dcfda89 Return 'eagain' when request queue is full and then try the request again.
In the worst case is the request queue remains full and we loop between
the NIF and Erlang forever trying over and over to enqueue the request. If
that happens we shouldn't take schedulers offline as the NIF calls are fast
and we shouldn't run out of memory as that is bounded.  CPU will show a lot
of activity, but progress will continue in Erlang.

f043a99ccb Merge pull request #8 from basho-labs/gsb-recycle-reqs

6b393ac47c Keep allocated req and ErlNifEnv around for reuse rather than re-alloc'ing them on each request should save us some overhead on the hot path. 2013-04-25 11:30:11 -04:00

fc59ae3f90 WIP: Finished transitioning to a gen_server and a few other tasks. This works
except that when trying to enif_send a bunch of messages eventually one causes
a segv just after reporting: size_object: bad tag for 0x80

652771003e WIP: a good start, I need to switch over wterl_event_handler to be a

process to the NIF API.

3310129918 * Check to make sure that all ASYNC_NIF_REPLY() calls are at the end of their
blocks, just before return and after releasing any local resources or locks.

* Check the return value of when setting up cursor caches so as not to miss an
ENOMEM or other error.

*Cleanup and free resources when closing a connection handle.

* Add a few missing mutex unlock calls on error paths.

* Ensure all resources are free'd/released/closed during truncate error paths.

* Free up alloc'ed copies of keys, cursor handles and sessions on unload.
