# WL#5004 Comprehensive Locking Stress Test for Azalea

|
|
# Grammar for testing DML, DDL, FLUSH, LOCK/UNLOCK, transactions
|
|
#
|

# Created:

# 2009-07 Matthias Leich (A few grammar items were taken from other grammar files.)
|
|

|
|
# Attention:
|
|
# There are modified grammar items because of

|
# - Bug#46339 crash on REPAIR TABLE merge table USE_FRM
|
|
# - Bug#46425 crash in Diagnostics_area::set_ok_status , empty statement, DELETE IGNORE

# Duplicate of Bug#30977 Concurrent statement using stored function and DROP FUNCTION breaks SBR
|
|
# .. there are a lot more please search for open bugs reported by Matthias Leich
|
|
#
|
|
# TODO:
|
|
# - Correct spelling is "namespace" and not "name space"
|
|
# - Add TRUNCATE PARTITION and check if we are missing any other related DDL.
|
|
# (Bug #49907 ALTER TABLE ... TRUNCATE PARTITION does not wait for locks on the table)
|
|
# - Observation of Philip when using greater values for name_space_width
|
|
# - the database never actually gets the expected number of objects.
|
|
# Even if the DROPs are removed ,then still the database grows very slowly towards the name_space size.
|
|
# - There are a lot of CREATE TABLE table2 SELECT * FROM table1 and similar constructs in order to clone database objects.
|
|
# Unfortunately, at higher name_space values, table1 is not very likely to exist, and therefore table2 is also unlikely to be created.
|
|
# Conclusion(mleich):
|
|
# - reduce the likelihood of DROP TABLE <table with short lifetime>
|
|
# --> such tables get an a bit longer lifetime
|
|
# - reduce the likelihood that CREATE TABLE <table with short lifetime> uses "used_select"
|
|
# - Add subtest for
|
|
# Bug #48315 Metadata lock is not taken for merged views that use an INFORMATION_SCHEMA table
|
|
# Simple:
|
|
# Philip: using an I_S in a meaningless subselect would be best, just have
|
|
# ( SELECT user + 0 FROM INFORMATION_SCHEMA.USERS LIMIT 1)
|
|
# Complete:
|
|
# mleich:
|
|
# But IS tables used in VIEWs, SELECT, DELETE/UPDATE subqueries/join,
|
|
# PROCEDURES etc. are complete missing.
|
|
# Could I inject this in a subquery?
|
|
# - Simplify grammar:
|
|
# Name space concept is good for grammar development, avoiding failing statements,
|
|
# understanding statement logs but bad for grammar simplification speed.
|
|
#
|
|
# Bug#45225 Locking: hang if drop table with no timeout
|
|
# Reporter , LockTableKiller might help
|
|
#
|
|
# General architecture rules:
|
|
# ---------------------------
|
|
# 1. Do not modify the objects created by gendata.pl within this grammar file.
|
|
# Work on copies of these objects instead. Hereby we prevent that we totally run out of tables
|
|
# or rows etc. This minimizes also any locks on the objects created by gendata.pl.
|
|
# Do not
|
|
# - have tables of "special" types (partitioned, view, merge etc.)
|
|
# - variate the storage engine
|
|
# within your object creation grammar file.
|
|
# 2. Have separated name spaces for objects (tables etc.) with configurable width.
|
|
# - This allows to reduce the likelihood of applying a statement in general or an option to
|
|
# an object which is not allowed. Example: TRUNCATE TABLE <view>
|
|
# - Debugging of grammar and understanding server logs becomes easier if the name space
|
|
# for an object of some type contains type related strings like "base","temp",.. etc.
|
|
# Example: If there is a
|
|
# CREATE VIEW <name which does not belong into the VIEW name space>
|
|
# than something works not like intended.
|
|
# - The configurable name space width (-> $name_space_width) allows to influence the likelihood
|
|
# that some statement hits an object. This gives some control over how much the system is stressed.
|
|
# - The non default option to put all table related objects (base tables, views, etc.) allows
|
|
# some additional increase of the stress though the likelihood of failing statement raises.
|
|
# 3. Distinct between two kinds of object name spaces and treat the corresponding objects different.
|
|
# This is experimental and might be removed in case it does not fulfill the expectations.
|
|
# "Sequence" ("_S"):
|
|
# - statement sequence: CREATE object, fill in content (if applicable), COMMIT, wait some
|
|
# random timespan (-> SLEEP( ... * rand_val * $life_time_unit )) , DROP object
|
|
# - The COMMIT is intentional. It should ensure that the session running the sequence does
|
|
# not hold any locks on the object during the wait phase. I am aware that CREATE ... AS SELECT
|
|
# commits at end, but this might be changed somewhere in future.
|
|
# - the maximum of the random wait timespan is configurable (-> $max_table_life_time).
|
|
# - The object must be stored within a database created with the "_S" property.
|
|
# - No other DDL on this object
|
|
# This should ensure that other sessions have a chance to run several DML statements using this object
|
|
# before it gets dropped. The "Sequence" objects are of nearly no value when running with only one thread.
|
|
# "Normal" ("_N"):
|
|
# - CREATE and DROP for these objects are not within the same sequency.
|
|
# - Any session could run DDL (including DROP, ALTER, REPAIR etc.) on this object.
|
|
# - The object can be stored within any database.
|
|
# - It is assumed that they have a short lifetime.
|
|
# This should ensure that a session running a transaction with DML on this object has a chance to meet
|
|
# an attempt of another session to run DDL (especially ALTER) on this object.
|
|
# 4. There is some "generalization" (I am unsure if this is a good understandable term) of variables and
|
|
# a corresponding walk up of values.
|
|
# $database_name_* --> $database_name
|
|
# $base_table_name_* --> $base_table_name --> $table_name
|
|
# $temp_table_name_* --> $temp_table_name --> $table_name
|
|
# ...
|
|
# $part_table_name_* --> $part_table_name --> $table_name
|
|
# This means:
|
|
# If you run "table_item" which picks a table of random type (base table, temp table ...) and random lifetime
|
|
# and a corresponding database and automatically assigns values to variables ($database_*,$*_table_name_*)
|
|
# where the name cannot be predicted, you can find the generated names at least within
|
|
# $database_name and $table_name .
|
|
# Please be aware that for example a succeeding call of "procedure_item" modify the content of $database_name .
|
|
#
|
|
#
|
|
# Rules by thumb and experiences (important when extending this grammar file):
|
|
# ----------------------------------------------------------------------------
|
|
# 1. Any statement sequence has to be in one line.
|
|
# 2. Be aware of the dual use of ';'. It separates SQL statements in sequences and closes the definition block
|
|
# of a grammar item. So any ';' before some '|' has a significant impact.
|
|
# 3. Strange not intended effects: '|' or ':' instead of ';' ?
|
|
# 4. There is an open RQG problem with SHOW ... LIKE '<grammar item>'.
|
|
# 5. If there are needs to write some message into a server log than avoid the use of auxiliary SQL (SELECT <message> etc.).
|
|
# Use something like:
|
|
# /* <your text> */
|
|
# instead.
|
|
# 6. Use uppercase characters for strings and keywords in statements. This avoids any not intended
|
|
# treatment as grammar item.
|
|
# 7. Use the most simple option first in lists. This makes automatic grammar simplification
|
|
# which walks from right to left more efficient. Example:
|
|
# where:
|
|
# <empty> | WHERE `pk` BETWEEN _digit AND _digit | WHERE function_name_n() = _digit ;
|
|
#
|
|
|
|
# Naming conventions (default)
|
|
# ========================================================
|
|
#
|
|
# Pattern (standard configuration) | Object
|
|
# -----------------------------------------
|
|
# testdb_* | database
|
|
# t1_* | table/view
|
|
# p1_* | procedure
|
|
# f1_* | function
|
|
# p1_* | procedure
|

# tr1_* | trigger

# End of grammar item name (default) | characteristic
|
|
# -------------------------------------------------------
|
|
# _S | related to "sequence" object
|
|
# _N | related to "normal" object
|
|
#
|
|
# Within grammar item name | characteristic
|
|
# -----------------------------------------------
|
|
# _name | name of the object
|
|
# _item | <schema name> . <name of the object>
|
|
# _list | either single item (<schema name> . <name of the object>) or comma separated list
|
|
# | of such items
|
|
|
|
#
|
|
# Missing but not really important improvements:
|
|
# - Reduce the amount of cases where "sequence" objects have "normal" objects within their definition.
|
|
# --> views,functions,procedures
|
|
# - Reduce the amount of cases where the wrong table types occur within object definitions
|
|
# Example: TABLE for a TRIGGER or VIEW definition. Names of temporary tables could be computed but are not allowed.

# 1. The scenario of a KILL failing because the session does not exist is covered by:
|
|
# a) Current session id is minimum or maximum of all existing id's and lower_id or higher_id
|
|
# does not exist -> NULL as value for @kill_id. "KILL NULL" gets valuated as "KILL 0".
|
|
# b) A parallel session kills the session with the just computed id before we run the KILL.
|
|
# 2. It is intentional that I do not use "KILL _digit".
|
|
# 2.1 In case the RQG test crashes in a scenario with thread=1, it is very likely that during analysis
|
|
# the test gets converted to a script for mysqltest. Most probably the mysqltest simplifier gets
|
|
# applied and than it is very likely that the session id's change. The use of a computation
|
|
# based on CONNECTION_ID(), MIN and MAX leads to more stable results.
|
|
# 2.2 There is the risk that we compute the id iand KILL an auxiliary RQG session (reporter,validator).
|
|
# 2.2.1 The impact of such an operation on RQG (automatic judgement about test result, deadlock detection
|
|
# etc. is currently unknown.
|
|
# 2.2.2 Effects caused by killing of such an auxiliary RQG session are out of testing scope.
|
|
# Therefore we avoid this by the grammar item "pick_executors_only"
|
|
# etc. is currently unknown.
|
|
# 2.3 We must avoid to kill a test executor session within an early phase when it probably pulls
|
|
# meta data (table names, column names, data types, ...). This could end up with RQG exit status 255.
