ISSUE: https://github.com/FirebirdSQL/firebird/issues/7652
|
||||
TITLE: Make the profiler store aggregated requests by default, with option for detailed store
|
||||
DESCRIPTION:
|
||||
Test executes two times script with loop which does call to trivial stored procedure.
|
||||
First time we launch profiler without any parameters except session name, then - with 'DETAILED_REQUESTS'.
|
||||
In both cases (after finish profiling) we run SQL against tables plg$prof_requests and plg$prof_psql_stats
|
||||
and obtain TWO aggregated values: count number of records with request_id = 0 and request_id <> 0.
|
||||
For case when we call profiler WITHOUT any parameters (except session name):
|
||||
* before this ticket was implemented (for builds with date <= 27-JUN-2023) data in both mentioned tables
|
||||
did not contain records with request_id = 0 (i.e. all rows had request_id > 0);
|
||||
* after implementation ( https://github.com/FirebirdSQL/firebird/commit/00bb8e4581b66b624de47bfcde6b248e163ec6c1 )
|
||||
all rows in tables plg$prof_requests and plg$prof_psql_stats have request_id > 0.
|
||||
For case when we call profiler WITH 'DETAILED_REQUESTS':
|
||||
* builds with date <= 27-JUN-2023 could not be used, exception raised:
|
||||
Statement failed, SQLSTATE = 42000
|
||||
validation error for variable ATTACHMENT_ID, value "*** null ***"
|
||||
-At function 'RDB$PROFILER.START_SESSION'
|
||||
* after implementation all rows in tables plg$prof_requests and plg$prof_psql_stats have request_id > 0.
