|
# #
|
|
# Testing of values within INFORMATION_SCHEMA.PROCESSLIST #
|
|
# #
|
|
# Ensure that the values fit to the current event of the connection #
|
|
# and especially that they change if a connection does nothing or #
|
|
# runs some SQL. #
|
|
# Examples: #
|
|
# - change the default database #
|
|
# - send some time no SQL command to the server #
|
|
# - send a long running query #
|
|
# #
|
|
# Note(mleich): #
|
|
# 1. Please inform me if this test fails because of timing problems. #
|
|
# I tried to avoid instabilities but the values within the column #
|
|
# TIME are very sensible to fluctuations of the machine load. #
|
|
# I had to unify some TIME values with "--replace_result" in cases #
|
|
# where they are too unstable. #
|
|
# 2. Storage engine variants of this test do not make sense. #
|
|
# - I_S tables use the MEMORY storage engine whenever possible. #
|
|
# - There are some I_S table which need column data types which #
|
|
# are not supported by MEMORY. Example: LONGTEXT/BLOB #
|
|
# MyISAM will be used for such tables. #
|
|
# The column PROCESSLIST.INFO is of data type LONGTEXT #
|
|
# ----> MyISAM #
|
|
# - There is no impact of the GLOBAL(server) or SESSION default #
|
|
# storage engine setting on the engine used for I_S tables. #
|
|
# That means we cannot get NDB or InnoDB instead. #
|
|
# 3. The SHOW (FULL) PROCESSLIST command are for comparison. #
|
|
# The main test target is INFORMATION_SCHEMA.PROCESSLIST ! #
|
|
# #
|
|
# Creation: #
|
|
# 2007-08-09 mleich Implement this test as part of #
|
|
# WL#3982 Test information_schema.processlist #
|
|
# 2008-01-05 HHunger Changed time test and long statement test. #
|
|
# It could happen that the long statement test #
|
|
# fail due to timing problems. #
|
|
# 2008-04-14 pcrews Changed --replace_columns to include host #
|
|
# this is due to failure occurring on Windows #
|
|
# Win results included port number as well causing #
|
|
# test failures #
