A number of jni calls were "stateless", which meant they allocated their
own vtmgr and mpool instances each time invoked. Instead invoke them
with the global jni closure and add to it vtmgr (already has mpool) and
use these instead of allocating/freeing each time. To make sure no race
conditions are introduced (mpool, though debug-only, is probably not
thread-safe), guard these new uses with an in-use flag. If that fires
I'll need a mutex or something.
Once the pool count drops to 0, start showing the number of tiles left
in the user's tray. This prevents there being a long time when nothing
seems to be changing *and* the script from exiting early because it
thinks all games are hung.
Somehow I got a wordlist into a location different from what was
recorded in the DB table and since the delete command matched on
location as well as name it was never deleted (which meant the checksum
was never updated and so upgrading never seemed to succeed.) Removing
the match on location fixed that problem, and since I don't see any harm
in cacheing only one version of a wordlist will simply leave it that
way.
Did a bunch of cleanup as well.
I'm seeing several IllegalStateException crashes due to e.g. having an
alert posted when app's in the background. Need to fix them, but the
debug build crashing isn't helpful. Log.e() instead.
The pesky thing is back. When app's in the background with an
unconnected game open displaying the "resend/wait" alert and the game
connects get IllegalStateException because the fragment stack's being
modified after onSaveInstanceState() (or, because the dialog fragment,
saved as an instance variable in BoardDelegate, dates from an earlier
state. Anyway, catching and dropping the exception and elsewhere failing
silently to rebuild the alert seems to fix the problem, but the right
fix is likely different. I suspect hanging onto that iVar is wrong, and
that the dialog should go away when onStop() is called and then be
rebuilt later from saved state. But for now, not crashing is good.
