deadlocks
by Bill Burke
I"m getting concurrent deadlocks when doing a login with multiple
threads. Its just bizarre and I don't get it. Check out this error
message. Why the hell would "delete from AuthProviders" be called
??????!?!?!?!?!!! I don't see a setAuthProviders happening anywhere.
Caused by: org.h2.jdbc.JdbcSQLException: Deadlock detected. The current
transaction was rolled back. Details: "
Session #8 (user: SA) is waiting to lock PUBLIC.USERSESSIONENTITY while
locking PUBLIC.AUTHENTICATIONLINKENTITY (exclusive), PUBLIC.USERENTITY
(exclusive), PUBLIC.AUTHPROVIDERS (exclusive).
Session #5 (user: SA) is waiting to lock PUBLIC.AUTHPROVIDERS while
locking PUBLIC.USERSESSIONENTITY (exclusive)."; SQL statement:
delete from AuthProviders where RealmEntity_id=? [40001-161]

Fixes since beta-1??
by Bill Burke
Doing a release tomorrow morning (US - EST). Were there any fixes from
beta 1? I saw a bunch of PRs. If you know what they are, please
add/close JIRA targeted at beta-2.

FYI: month behind
by Bill Burke
FYI, we're a month behind on our schedule, so I pushed all the dates out
a month or more on all the releases. 1.0.Final will be August 21. We
may release sooner depending on how the performance work goes.
