# title: SELECT WITH LOCK may enter an infinite loop for a single record
|
|
# decription:
|
|
# Caution: could not reproduce on neither WI-T3.0.0.30566 Firebird 3.0 Alpha 1 nor WI-T3.0.0.30809 Firebird 3.0 Alpha 2.

# Any advice about how this test should be properly written will be appreciated.
|
|
# Added separate code for 4.0 because isc_update_conflict now can be primary code of exception reason
|
|
# (after consulting with Vlad, letter 06-aug-2018 16:27).
|
|
#
|
|
# 01-apr-2020. Expected STDERR section for 4.0.x was changed BACK TO PREVIOUS set of messages, i.e.:
|
|
# 1. Statement failed, SQLSTATE = 40001
|
|
# 2. deadlock <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<< THIS LINE APPEARED SINCE 4.0.0.1848
|
|
# 3. update conflicts with concurrent update
|
|
# 4. concurrent transaction number is ...
|
|
# Confirmed by Alex, letter 31.03.2020 12:01.
|
|
#
|
|
# Checked on:
|
|
# 3.0.4.33022: OK, 5.453s.
|
|
# 4.0.0.1158: OK, 5.313s.
|
|
#
|
|
# 21.09.2020: removed separate section for 4.0 because error messages equal to FB 3.x. Changed 'substitution' section.
|
|
#
|
|
# Waiting for completion of child ISQL async process is done by call <isql_PID>.wait() instead of old (and "fragile")
|
|
# assumption about maximal time that it could last before forcedly terminate it.
|
|
#
|
|
# Replaced direct specification of executable 'isql' with context['isql_path'] in order to remove dependence on PATH
|
|
# (suggested by dimitr, letter 28.08.2020, 13:42; otherwise directory with isql must be added into PATH list).
