ISSUE: 6633
|
|
TITLE: Allow usage of time zone displacement in config DefaultTimeZone
|
|
DESCRIPTION:
|
|
We make backup of current firebird.conf for changing it two times:
|
|
1. Add line with DefaultTimeZone = -7:00 and get local time by making *LOCAL* connect to current DB;
|
|
2. Restore previous firebird.conf from its .bak-copy do second change: add line with DefaultTimeZone = 7:00.
|
|
Then we run second local connect.
|
|
|
|
Each connect will ask FB to return CURRENT_TIME value (with casting it to '%H:%M:%S' format).
|
|
Expected result: values must change from 1st to 2nd run for 14 hours (840 minutes).
|
|
|
|
::: NB :::
|
|
1. Affect of changed parameter DefaultTimeZone can be seen only if DB is attached using *LOCAL* protocol.
|
|
Attempt to connect using remote protocol will fail: engine returns previous value of DefaultTimeZone.
|
|
One need to wait at least 130 seconds after changing firebird.conf for new value be returned at this case!
|
|
The reason of that is 10+60+60 seconds which are needed to fully unload shmem-related structures from memory.
|
|
Explanation from Vlad: letter 24.01.2021 18:00, subj: "System audit in FB. Is there some kind of timeout of 130 seconds ?"
|
|
(it was discussion about attempts make test for CORE-5993)
|
|
See also: http://tracker.firebirdsql.org/browse/CORE-6476
|
|
|
|
2. FDB driver loads client library only *once* before this test launch and, in turn, this library reads firebird.conf.
|
|
For this reason we have to launch separate (child) process two times, which will be forced to load firebird.conf
|
|
every launch. This is why subprocess.call(['isql', ...]) is needed here rather than just query DB using cursor of
|
|
pre-existing db_conn connection (see routine 'get_local_time').
|
|
|
|
Confirmed improvement on 4.0.0.2185.
|
|
Value of time did not differ on previous builds (checked 4..0.2170).
