# title: Regression: Cancel Query function no longer works
|
|
# decription:
|
|
# We create .sql script with 'heavy query' that for sure will run more than several seconds.
|
|
# Then we launch asynchronous ISQL process to perform this query and take small pause for 1-2 second.
|
|
# After this we send signal CTRL_C_EVENT for emulating interruption that is done by pressing Ctrl-C.
|
|
# Then we wait for process finish (call wait() method) - this is necessary if ISQL will continue
|
|
# without interruprion (i.e. if something will be broken again).
|
|
#
|
|
# When method wait() will return control back, we can obtain info about whether child process was
|
|
# terminated or no (using method poll()). If yes (expected) then it must return 1.
|
|
#
|
|
# Finally, we check ISQL logs for STDOUT and STDERR. They must be as follows:
|
|
# * STDOUT -- must be empty
|
|
# * STDERR -- must contain (at least) two phrases:
|
|
# 1. Statement failed, SQLSTATE = HY008
|
|
# 2. operation was cancelled
|
|
#
|
|
# ::: NB :::
|
|
# Windows only: subprocess.Popen() must have argument: creationflags = subprocess.CREATE_NEW_PROCESS_GROUP
|
|
# Otherwise we can not send signal Ctrl_C_EVENT to the child process.
|
|
# Linux: parameter 'creationflags' must be 0, signal.SIGINT is used instead of Ctrl_C_EVENT.
|
|
#
|
|
# See: https://docs.python.org/2.7/library/subprocess.html
|
|
#
|
|
# Confirmed bug on 4.0.0.2307: query could NOT be interrupted and we had to wait until it completed.
|
|
# Checked on 4.0.0.2324 (SS/CS): works OK, query can be interrupted via sending Ctrl-C signal.
|
|
#
|
|
# 16.04.2021. Adapted for run both on Windows and Linux. Checked on:
|
|
# Windows: 4.0.0.2422 SS/CS
|
|
# Linux: 4.0.0.2422 SS/CS
