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.
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.
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.
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.
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.
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.
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.
than those in the various queues. Reenable the (still failing)
truncate tests (because they don't SEGV anymore). Still might be
a memory leak, next up is valgrind.
the request queue over to a simple fifo queue which could (if needed)
be made lock-free. Cursor searches can optionally now specifiy that
they are mid-scan so as not to have their cursor handles reset every
call.
stop sending it over. Allow the user to set a "type" of storage
in their config to either 'table' for btree or 'lsm' for a log
structured merge tree. Various other cleanup.
dtor commented out, otherwise it would SEGV on GC. Some of the truncate
tests fail (race?) but don't SEGV, so that's not so bad. Fixed numerous
issues and also removed a mutex and queue of idle worker threads because
it isn't used so why bother with it?
