22643fc312 Change from waking up all threads to waking up one thread. 2013-04-14 13:54:45 -04:00
Gregory Burd
8fe9dc9bad This is a different approach from async2, instead of a single queue 
and many workers this has a queue per scheduler and a few workers per
queue.

456129e7f3 Reusing closed cursors is bad for your health (SEGV), don't do that. 
Also a bit of paranoia, bzero after all enif_alloc calls.

1962640382 Move the cleanup code into conn_close and remove the need for a dtor 
function for resource GC/cleanup.  It's easier.

b0ca1e4098 WIP -- 41 tests pass, 3 fail = progress! Right now I have the connection 
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?

5a73264307 WIP -- Most tests passing, truncate and drop failing due to EBUSY, 
also not sure why there is a segv when exiting but not in gdb.
Unlock mutex before returning error codes.  Alloc/free copies of some
strings allocated on the stack.

5ac006630e WIP -- tests failing -- WIP 
Fixed numerous bugs.  Pushed config_to_bin down to just before
calling the _nif() function, everywhere else config is a proplist.

2675aa501a Opening a connection now involves passing in both a configuration 
string for the connection and for any sessions.  Don't convert
configuration proplists into strings (Erlang binaries) until calling
into the NIF layer.

07592f20fb Use non-cursor ops for get/put/delete because under the covers they 
are reusing sessions and cursors in the NIF layer.  Keep two cursors
open for just the house keeping tasks, is_empty and stats.

Changes required to iron out compiler errors, warnings, etc.  Code now

19268b7c77 WIP-- Not Yet Compiling or Functional -- WIP 
* No longer expose WT_SESSION into Erlang at all as WT's model is to
maintain one WT_SESSION per-thread and we don't know anything about
threads in Erlang.

* async_nif worker threads don't pull both mutexes on every loop
when processing requests, only one

* async_nif provides a worker_id (int, 0 - MAX_WORKERS) within the
work block scope which we use to find our per-worker WT_SESSIONs

* async_nif maintained a number of globals which I'm moving into
the NIF's priv_data so that on upgrade/reload we have a fighting
chance to "Do the Right Thing(TM)".

* NIF Upgrades/Reloads started to plumb this in.

* Use a khash to manage the cache of URI->WT_CURSORs per WT_SESSION.

* Added start/stop positions into truncate call to allow for truncating
sub-ranges data.

* Lots of other details I'm sure I've forgotten and more left undone.
Search for "TODO:" or try to compile to see what's left, and then
there is a need for a lot more tests given all this new complexity.

77e0dacdb5 Use a set of {Session, Cursor} pairs ("passes") for calls into WiredTiger 
to avoid a) opening a large number of Sessions or Cursors and b) avoid
reusing a Session/Cursor pair in more than one thread.  Each operation,
except folds, use the Session/Cursor pair corresponding to the scheduler
id (roughly "core") they are running on.  Each vnode instance will have
(count(schedulers) + count(active folds)) Session/Cursor pairs in use so
be sure to set session_max large enough when opening the connection to
WiredTiger.  This method will cause problems with scheduler threads going
to "sleep" so be sure to run schedmon to wake them up.
