# title: Server ignores asynchronous (monitoring or cancellation) requests while preparing a query with lot of windowed functions
|
|
# decription:
|
|
# Preparing stage of test query will last lot of time even on power host.
|
|
# We launch separate (child) process with ISQL and allow him to start preparing this query during several
|
|
# seconds. Then we launch second child process with ISQL and try to kill first one.
|
|
# Before this ticket was fixed it was NOT possible neither to cancel it by using MON$ATTACHMENTS nor even
|
|
# query MON$ tables at all (until this 'complex query' preparing finish).
|
|
#
|
|
# Checked on WI-V3.0.0.32081, SS / SC / CS. Result: all fine.
|
|
# 11.05.2017: checked on WI-T4.0.0.638 - added filtering to messages about shutdown state, see comments below.
