Hi,
attached are the new patches.
The base patch is now simplified and is about 10K smaller:
- no more individual Init* and Destroy* functions
- Check* functions don't check for "now", it's done centrally by the signal handler
- CheckDeadLock() is moved back to proc.c and made public for timeout.c
- a new header storage/proctimeout.h is introduced, so timeout.c can know
about CheckDeadLock()
The lock_timeout patch gained a new feature and enum GUC:
SET lock_timeout_option = { 'per_lock' | 'per_statement' } ;
'per_lock' is the default and carries the previous behaviour: the timeout value
applies to all locks individually. The statement may take up to N*timeout.
'per_statement' behaves like statement_timeout. The important difference is
that statement_timeout may trigger during the executor phase when a long
result set is already being returned to the client and the transfer is cut because
of the timeout. On the other hand, lock_timeout may only trigger during locking
the objects and if all locks were granted under the specified time, the result set
is then returned to the client.
Best regards,
