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
gen_server and I need to add a way to set the pid of the message handler
process to the NIF API.

554aba4331 Truncate table isn't used by the WiredTiger Riak/KV backend API and it is
currently failing.  Comment out of the tests, for now.

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.

d505f7f9c8 Whitespace. Call wterl:drop not truncate for drop calls and set force
to true when calling so that we ignore ENOENT.  Change the session estimate
down a bit.

01a8926160 Shared libs and files linking to them must be copied into our priv
dir so that at runtime we can find the correct files.

8d8ceecc8b enif_get_string can return < 1 when it copies less than the buffer size
you pass into it, that'd result in a non-zero (aka true) test when in fact
it's a problem if the argument isn't passed completely (however unlikely
that is).

enif_alloc_env() requires that later you enif_free_env() which I wasn't doing,
this seems to keep memory steady in test runs.

83bca853f3 Store copies of Uri as keys in the hash table. 2013-04-18 11:47:12 -04:00

60dd048b7e Move the FIFO Queue implementation into its own file (fifo_q.h). Work
on the nif_unload path.  Free up resources owned by wterl.c when
unloading.  Continue to evolve the build script.  Add to khash the ability
to create a hash that maps from a pointer to a value. There is still a segv
due to a race wterl.c:do_unload() which needs to be addressed.

db953f5b39 Moved num_queue estimate earlier so as to ensure that the amount of
memory allocated, zero'ed and free'd was consistent.  Skip free'ing
async environment as Erlang will free that for us when we no longer
reference it.  Fix the memory leak (or at least one of them) by no
longer copying the Uri into the hash table.

1ae8e5698f Ensure that the ratio of workers to queues is 2:1 and that there are at
least 2 queues regardless.  Fix a few race conditions (h/t Sue from
WiredTiger for some nice work) and cherry pick (for now) a commit that
fixes a bug I triggered and Keith fixed (in < 10min from report) related
to WiredTiger stats.  Ensure that my guesstimate for session_max is no
larger than WiredTiger can manage.  Continue to fiddle with the build
script.

f664c303d8 Disable prefix compression (for now). 2013-04-17 14:23:56 -04:00
Gregory Burd
123dfa600e Simplified the worker look function. Added ability to pick block
compressor in config, default is snappy, off is {block_compressor, none}.

87f70d75a1 Inline the fifo_q functions to speed them up and silence compiler warnings
for unused API calls.  Add a fifo_q_full call to hide the details of that.
Alloc work queues along with the async_nif at the end of that memory block.
Fix a few places where things should be free'd and were not.  Change enqueue
to return 0 when shutting down.  Fix a race related to shutdown.  When I use
gdb eunit calls ?cmd() seem to fail, so I've created rmdir:path() to replace
?cmd("rm -rf path") calls.

13a9036764 So, WiredTiger prefers that extensions be shared libraries however those
extensions reference other shared libraries.  Previously I tried to turn
all those shared libs into static libs, however that didn't pan out so well.
So now the libwiredtiger.so library is loaded by wterl.so also, later on
during use libwiredtiger.so will load libwiredtiger_snappy.so and
libwiredtiger_bzip2.so which now have libsnappy.a and libbz2.a respectively
linked statically so as to avoid confusion.

ba41dd7fb6 Use the table name in get/put/delete calls to form an "affinity" with a
worker queue so that we spread work around and make it more likely that
work for a given table goes first to a given set of worker threads.
