NAME

       mysql-test-run.pl - run MariaDB test suite

SYNOPSIS

       mysql-test-run.pl [options]

DESCRIPTION

       The mysql-test-run.pl Perl script is the main application used to run the MariaDB test
       suite. It invokes mysqltest to run individual test cases.

       Invoke mysql-test-run.pl in the mysql-test directory like this:

           shell> mysql-test-run.pl [options] [test_name] ...

       Each test_name argument names a test case. The test case file that corresponds to the test
       name is t/test_name.test.

       For each test_name argument, mysql-test-run.pl runs the named test case. With no test_name
       arguments, mysql-test-run.pl runs all .test files in the t subdirectory.

       If no suffix is given for the test name, a suffix of .test is assumed. Any leading path
       name is ignored. These commands are equivalent:

           shell> mysql-test-run.pl mytest
           shell> mysql-test-run.pl mytest.test
           shell> mysql-test-run.pl t/mytest.test

       A suite name can be given as part of the test name. That is, the syntax for naming a test
       is:

           [suite_name.]test_name[.suffix]

       If a suite name is given, mysql-test-run.pl looks in that suite for the test. The test
       file corresponding to a test named suite_name.test_name is found in
       suite/suite_name/t/test_name.test. There is also an implicit suite name main for the tests
       in the top t directory. With no suite name, mysql-test-run.pl looks in the default list of
       suites for a match and runs the test in any suites where it finds the test. Suppose that
       the default suite list is main, binlog, rpl, and that a test mytest.test exists in the
       main and rpl suites. With an argument of mytest or mytest.test, mysql-test-run.pl will run
       mytest.test from the main and rpl suites.

       To run a family of test cases for which the names share a common prefix, use the
       --do-test=prefix option. For example, --do-test=rpl runs the replication tests (test cases
       that have names beginning with rpl).  --skip-test has the opposite effect of skipping test
       cases for which the names share a common prefix.

       The argument for the --do-test and --skip-test options also allows more flexible
       specification of which tests to perform or skip. If the argument contains a pattern
       metacharacter other than a lone period, it is interpreted as a Perl regular expression and
       applies to test names that match the pattern. If the argument contains a lone period or
       does not contain any pattern metacharacters, it is interpreted the same way as previously
       and matches test names that begin with the argument value. For example, --do-test=testa
       matches tests that begin with testa, --do-test=main.testa matches tests in the main test
       suite that begin with testa, and --do-test=main.*testa matches test names that contain
       main followed by testa with anything in between. In the latter case, the pattern match is
       not anchored to the beginning of the test name, so it also matches names such as
       xmainytesta.

       To perform setup prior to running tests, mysql-test-run.pl needs to invoke mysqld with the
       --bootstrap and --skip-grant-tables options. If MySQL was configured with the
       --disable-grant-options option, --bootstrap, --skip-grant-tables, and --init-file will be
       disabled. To handle this, set the MYSQLD_BOOTSTRAP environment variable to the full path
       name of a server that has all options enabled.  mysql-test-run.pl will use that server to
       perform setup; it is not used to run the tests.

       The init_file test will fail if --init-file is disabled. This is an expected failure that
       can be handled as follows:

           shell> export MYSQLD_BOOTSTRAP
           shell> MYSQLD_BOOTSTRAP=/full/path/to/mysqld
           shell> make test force="--skip-test=init_file"

       To run mysql-test-run.pl on Windows, you´ll need either Cygwin or ActiveState Perl to run
       it. You may also need to install the modules required by the script. To run the test
       script, change location into the mysql-test directory, set the MTR_VS_CONFIG environment
       variable to the configuration you selected earlier (or use the --vs-config option), and
       invoke mysql-test-run.pl. For example (using Cygwin and the bash shell):

           shell> cd mysql-test
           shell> export MTR_VS_CONFIG=debug
           shell> ./mysqltest-run.pl --force --timer
           shell> ./mysqltest-run.pl --force --timer --ps-protocol

       mysql-test-run.pl uses several environment variables. Some of them are listed in the
       following table. Some of these are set from the outside and used by mysql-test-run.pl,
       others are set by mysql-test-run.pl instead, and may be referred to in tests.

       The variable MTR_PORT_BASE was added in MySQL 5.1.45 as a more logical replacement for
       MTR_BUILD_THREAD. It gives the actual port number directly (will be rounded down to a
       multiple of 10). If you use MTR_BUILD_THREAD, the port number is found by multiplying this
       by 10 and adding 10000.

       Tests sometimes rely on certain environment variables being defined. For example, certain
       tests assume that MYSQL_TEST is defined so that mysqltest can invoke itself with exec
       $MYSQL_TEST.

       Other tests may refer to the last three variables listed in the preceding table, to locate
       files to read or write. For example, tests that need to create files will typically put
       them in $MYSQL_TMP_DIR/file_name.

       If you are running mysql-test-run.pl version 1 by setting MTR_VERSION, note that this only
       affects the test driver, not the test client (and its language) or the tests themselves.

       A few tests might not run with version 1 because they depend on some feature of version 2.
       You may have those tests skipped by adding the test name to the file
       lib/v1/incompatible.tests. This feature is available from MySQL 5.1.40.

       mysql-test-run.pl supports the options in the following list. An argument of -- tells
       mysql-test-run.pl not to process any following arguments as options.

       •   --help, -h

           Display a help message and exit.

       •   --big-test

           Allow tests marked as "big" to run. Tests can be thus marked by including the line
           --source include/big_test.inc, and they will only be run if this option is given, or
           if the environment variable BIG_TEST is set to 1. Repeat this option twice to run only
           "big" tests.

           This is typically used for tests that take a very long to run, or that use many
           resources, so that they are not suitable for running as part of a normal test suite
           run.

       •   --boot-dbx

           Run the mysqld server used for bootstrapping the database through the dbx debugger.

       •   --boot-ddd

           Run the mysqld server used for bootstrapping the database through the ddd debugger.

       •   --boot-gdb

           Run the mysqld server used for bootstrapping the database through the gdb debugger.

       •   --[mtr-]build-thread=number

           Specify a number to calculate port numbers from. The formula is 10 * build_thread +
           10000. Instead of a number, it can be set to auto, which is also the default value, in
           which case mysql-test-run.pl will allocate a number unique to this host.

           The value (number or auto) can also be set with the MTR_BUILD_THREAD environment
           variable.

           The more logical --port-base is supported as an alternative.

       •   --callgrind

           Instructs valgrind to use callgrind.

       •   --check-testcases

           Check test cases for side effects. This is done by checking system state before and
           after each test case; if there is any difference, a warning to that effect will be
           written, but the test case will not be marked as failed because of it. This check is
           enabled by default.

       •   --client-bindir=path

           The path to the directory where client binaries are located.

       •   --client-dbx

           Start mysqltest in the dbx debugger.

       •   --client-ddd

           Start mysqltest in the ddd debugger.

       •   --client-debugger=debugger

           Start mysqltest in the named debugger.

       •   --client-gdb

           Start mysqltest in the gdb debugger.

       •   --client-libdir=path

           The path to the directory where client libraries are located.

       •   --combination=value

           Extra options to pass to mysqld. The value should consist of one or more
           comma-separated mysqld options. This option is similar to --mysqld but should be given
           two or more times.  mysql-test-run.pl executes multiple test runs, using the options
           for each instance of --combination in successive runs. If --combination is given only
           once, it has no effect. For test runs specific to a given test suite, an alternative
           to the use of --combination is to create a combinations file in the suite directory.
           The file should contain a section of options for each test run.

       •   --comment=str

           Write str to the output within lines filled with #, as a form of banner.

       •   --compress

           Compress all information sent between the client and the server if both support
           compression.

       •   --cursor-protocol

           Use the cursor protocol between client and server (implies --ps-protocol).

       •   --dbx

           Start the mysqld(s) in the dbx debugger.

       •   --ddd

           Start the mysqld(s) in the ddd debugger.

       •   --debug

           Dump trace output for all clients and servers.

       •   --debug-common

           Same as --debug, but sets the 'd' debug flags to "query,info,error,enter,exit".

       •   --debug-server

           Use debug version of server, but without turning on tracing.

       •   --debugger=debugger

           Start mysqld using the named debugger.

       •   --debug-sync-timeout=N

           Controls whether the Debug Sync facility for testing and debugging is enabled. The
           option value is a timeout in seconds. The default value is 300. A value of 0 disables
           Debug Sync. The value of this option also becomes the default timeout for individual
           synchronization points.

           mysql-test-run.pl passes --loose-debug-sync-timeout=N to mysqld. The --loose prefix is
           used so that mysqld does not fail if Debug Sync is not compiled in.

       •   --defaults-file=file_name

           Use the named file as fixed config file template for all tests.

       •   --defaults_extra_file=file_name

           Add setting from the named file to all generated configs.

       •   --do-test=prefix|regex

           Run all test cases having a name that begins with the given prefix value, or fulfils
           the regex. This option provides a convenient way to run a family of similarly named
           tests.

           The argument for the --do-test option also allows more flexible specification of which
           tests to perform. If the argument contains a pattern metacharacter other than a lone
           period, it is interpreted as a Perl regular expression and applies to test names that
           match the pattern. If the argument contains a lone period or does not contain any
           pattern metacharacters, it is interpreted the same way as previously and matches test
           names that begin with the argument value. For example, --do-test=testa matches tests
           that begin with testa, --do-test=main.testa matches tests in the main test suite that
           begin with testa, and --do-test=main.*testa matches test names that contain main
           followed by testa with anything in between. In the latter case, the pattern match is
           not anchored to the beginning of the test name, so it also matches names such as
           xmainytestz.

       •   --dry-run

           Don't run any tests, print the list of tests that were selected for execution.

       •   --embedded-server

           Use a version of mysqltest built with the embedded server.

       •   --enable-disabled

           Ignore any disabled.def file, and also run tests marked as disabled. Success or
           failure of those tests will be reported the same way as other tests.

       •   --experimental=file_name

           Specify a file that contains a list of test cases that should be displayed with the [
           exp-fail ] code rather than [ fail ] if they fail.

           For an example of a file that might be specified via this option, see
           mysql-test/collections/default.experimental.

       •   --extern option=value

           Use an already running server. The option/value pair is what is needed by the mysql
           client to connect to the server. Each --extern option can only take one option/value
           pair as an argument, so you need to repeat --extern for each pair needed. Example:

                     ./mysql-test-run.pl --extern socket=var/tmp/mysqld.1.sock alias

           Note: If a test case has an .opt file that requires the server to be restarted with
           specific options, the file will not be used. The test case likely will fail as a
           result.

       •   --fast

           Do not perform controlled shutdown when servers need to be restarted or at the end of
           the test run. This is equivalent to using --shutdown-timeout=0.

       •   --force-restart

           Always restart servers between tests.

       •   --force

           Normally, mysql-test-run.pl exits if a test case fails.  --force causes execution to
           continue regardless of test case failure.

       •   --gcov

           Collect coverage information after the test. The result is a gcov file per source and
           header file.

       •   --gcov-src-dir

           Colllect coverage only within the given subdirectory. For example, if you're only
           developing the SQL layer, it makes sense to use --gcov-src-dir=sql.

       •   --gdb

           Start the mysqld(s) in the gdb debugger.

       •   --gprof

           Collect profiling information using the gprof profiling tool.

       •   --manual-dbx

           Use a server that has already been started by the user in the dbx debugger.

       •   --manual-ddd

           Use a server that has already been started by the user in the ddd debugger.

       •   --manual-debug

           Use a server that has already been started by the user in a debugger.

       •   --manual-gdb

           Use a server that has already been started by the user in the gdb debugger.

       •   --manual-lldb

           Use a server that has already been started by the user in the lldb debugger.

       •   --mark-progress

           Marks progress with timing (in milliseconds) and line number in
           var/log/testname.progress.

       •   --max-connections=num

           The maximum number of simultaneous server connections that may be used per test. If
           not set, the maximum is 128. Minimum allowed limit is 8, maximum is 5120. Corresponds
           to the same option for mysqltest.

       •   --max-save-core=N

           Limit the number of core files saved, to avoid filling up disks in case of a
           frequently crashing server. Defaults to 5, set to 0 for no limit. May also be set with
           the environment variable MTR_MAX_SAVE_CORE

       •   --max-save-datadir=N

           Limit the number of data directories saved after failed tests, to avoid filling up
           disks in case of frequent failures. Defaults to 20, set to 0 for no limit. May also be
           set with the environment variable MTR_MAX_SAVE_DATADIR

       •   --max-test-fail=N

           Stop execution after the specified number of tests have failed, to avoid using up
           resources (and time) in case of massive failures. retries are not counted, nor are
           failures of tests marked experimental. Defaults to 10, set to 0 for no limit. May also
           be set with the environment variable MTR_MAX_TEST_FAIL

       •   --mem

           This option is not supported on Windows.

           Run the test suite in memory, using tmpfs or ramdisk. This can decrease test times
           significantly, in particular if you would otherwise be running over a remote file
           system.  mysql-test-run.pl attempts to find a suitable location using a built-in list
           of standard locations for tmpfs and puts the var directory there. This option also
           affects placement of temporary files, which are created in var/tmp.

           The default list includes /dev/shm. You can also enable this option by setting the
           environment variable MTR_MEM[=dir_name]. If dir_name is given, it is added to the
           beginning of the list of locations to search, so it takes precedence over any built-in
           locations.

           Once you have run tests with --mem within a mysql-testdirectory, a soflink var will
           have been set up to the temporary directory, and this will be re-used the next time,
           until the soflink is deleted. Thus, you do not have to repeat the --mem option next
           time.

       •   --mysqld=value

           Extra options to pass to mysqld. The value should consist of one or more
           comma-separated mysqld options.

       •   --mysqld-env=VAR=VAL

           Specify additional environment settings for "mysqld". Use additional --mysqld-env
           options to set more than one variable.

       •   --nocheck-testcases

           Disable the check for test case side effects; see --check-testcases for a description.

       •   --noreorder

           Do not reorder tests to reduce number of restarts, but run them in exactly the order
           given. If a whole suite is to be run, the tests are run in alphabetical order, though
           similar combinations will be grouped together. If more than one suite is listed, the
           tests are run one suite at a time, in the order listed.

       •   --notimer

           Cause mysqltest not to generate a timing file. The effect of this is that the report
           from each test case does not include the timing in milliseconds as it normally does.

       •   --nowarnings

           Do not look for and report errors and warning in the server logs.

       •   --parallel={N|auto}

           Run tests using N parallel threads. By default, 1 thread is used. Use --parallel=auto
           for auto-setting of N.

       •   --[mtr-]port-base=P

           Specify base of port numbers to be used; a block of 10 will be allocated.  P should be
           divisible by 10; if it is not, it will be rounded down. If running with more than one
           parallel test thread, thread 2 will use the next block of 10 and so on.

           If the port number is given as auto, which is also the default, mysql-test-run.pl will
           allocate a number unique to this host. The value may also be given with the
           environment variable MTR_PORT_BASE.

           If both --build-thread and --port-base are used, --port-base takes precedence.

       •   --print-testcases

           Do not run any tests, but print details about all tests, in the order they would have
           been run.

       •   --ps-protocol

           Use the binary protocol between client and server.

       •   --record

           Pass the --record option to mysqltest. This option requires a specific test case to be
           named on the command line.

       •   --reorder

           Reorder tests to minimize the number of server restarts needed. This is the default
           behavior. There is no guarantee that a particular set of tests will always end up in
           the same order.

       •   --repeat=N

           Run each test N number of times.

       •   --report-features

           First run a "test" that reports MariaDB features, displaying the output of SHOW
           ENGINES and SHOW VARIABLES. This can be used to verify that binaries are built with
           all required features.

       •   --report-times

           Report how much time has been spent on different phases of test execution.

       •   --retry=N

           If a test fails, it is retried up to a maximum of N runs (default 1). Retries are also
           limited by the maximum number of failures before stopping, set with the
           --retry-failure option. This option has no effect unless --force is also used; without
           it, test execution will terminate after the first failure.

           The --retry and --retry-failure options do not affect how many times a test repeated
           with --repeat may fail in total, as each repetition is considered a new test case,
           which may in turn be retried if it fails.

       •   --retry-failure=N

           When using the --retry option to retry failed tests, stop when N failures have
           occurred (default 2). Setting it to 0 or 1 effectively turns off retries.

       •   --shutdown-timeout=SECONDS

           Max number of seconds to wait for servers to do controlled shutdown before killing
           them. Default is 10.

       •   --skip-combinations

           Do not apply combinations; ignore combinations file or option.

       •   --skip-rpl

           Skip replication test cases.

       •   --skip-ssl

           Do not start mysqld with support for SSL connections.

       •   --skip-test=regex|regex

           Specify a regular expression to be applied to test case names. Cases with names that
           match the expression are skipped. tests to skip.

           The argument for the --skip-test option allows more flexible specification of which
           tests to skip. If the argument contains a pattern metacharacter other than a lone
           period, it is interpreted as a Perl regular expression and applies to test names that
           match the pattern. See the description of the --do-test option for details.

       •   --skip-test-list=FILE

           Skip the tests listed in FILE. Each line in the file is an entry and should be
           formatted as: <TESTNAME> : <COMMENT>

       •   --skip-*

           --skip-* options not otherwise recognized by mysql-test-run.pl are passed to the
           master server.

       •   --sleep=N

           Pass --sleep=N to mysqltest.

       •   --sp-protocol

           Create a stored procedure to execute all queries.

       •   --ssl

           If mysql-test-run.pl is started with the --ssl option, it sets up a secure connection
           for all test cases. In this case, if mysqld does not support SSL, mysql-test-run.pl
           exits with an error message: Couldn´t find support for SSL

       •   --staging-run

           Run a limited number of tests (no slow tests). Used for running staging trees with
           valgrind.

       •   --start

           Initialize and start servers with the startup settings for the specified test case.
           You can use this option to start a server to which you can connect later. For example,
           after building a source distribution you can start a server and connect to it with the
           mysql client like this:

               shell> cd mysql-test
               shell> ./mysql-test-run.pl --start alias &
               shell> ../mysql -S ./var/tmp/master.sock -h localhost -u root

           If no tests are named on the command line, the server(s) will be started with settings
           for the first test that would have been run without the --start option.

           mysql-test-run.pl will stop once the server has been started, but will terminate if
           the server dies. If killed, it will also shut down the server.

       •   --start-and-exit

           Same --start, but mysql-test-run terminates and leaves just the server running.

       •   --start-dirty

           This is similar to --start, but will skip the database initialization phase and assume
           that database files are already available. Usually this means you must have run
           another test first.

       •   --start-from=test_name

           mysql-test-run.pl sorts the list of names of the test cases to be run, and then begins
           with test_name.

       •   --strace

           Run the "mysqld" executables using strace. Default options are -f -o var/log/'mysqld-
           name'.strace.

       •   --strace-client

           Create strace output for mysqltest, optionally specifying name and path to the trace
           program to use.

           Example: ./mysql-test-run.pl --strace-client=ktrace

       •   --strace-option=ARGS

           Option to give strace, replaces default option(s).

       •   --stress=ARGS

           Run stress test, providing options to mysql-stress-test.pl. Options are separated by
           comma.

       •   --suite[s]=suite_name...

           Comma separated list of suite names to run. The default is:
           "main-,archive-,binlog-,csv-,federated-,funcs_1-,funcs_2-,
           handler-,heap-,innodb-,innodb_fts-,innodb_zip-,maria-,
           multi_source-,optimizer_unfixed_bugs-,parts-,perfschema-,
           plugins-,roles-,rpl-,sys_vars-,unit-,vcol-".

       •   --stop-file=file

           If this file is detected, mysqltest will not start new tests until the file is removed
           (also MTR_STOP_FILE environment variable).

       •   --stop-keep-alive=sec

           Works with --stop-file, print messages every sec seconds when mysqltest is waiting to
           remove the file (for buildbot) (also MTR_STOP_KEEP_ALIVE environment variable).

       •   --suite-timeout=minutes

           Specify the maximum test suite runtime in minutes. The default is 360.

       •   --testcase-timeout

           Specify the maximum test case runtime in minutes. The default is 15.

       •   --timediff

           Used with --timestamp, also print time passed since the previous test started.

       •   --timer

           Cause mysqltest to generate a timing file. The default file is named ./var/log/timer.

       •   --timestamp

           Prints a timestamp before the test case name in each test report line, showing when
           the test ended.

       •   --tmpdir=path

           The directory where temporary file are stored. The default location is ./var/tmp. The
           environment variable MYSQL_TMP_DIR will be set to the path for this directory, whether
           it has the default value or has been set explicitly. This may be referred to in tests.

       •   --user=user_name

           The MariaDB user name to use when connecting to the server (default root).

       •   --user-args

           In combination with start* and no test name, drops arguments to mysqld except those
           specified with --mysqld (if any).

       •   --valgrind[-all]

           Run mysqltest and mysqld with valgrind. This and the following --valgrind options
           require that the executables have been built with valgrind support.

       •   --valgrind-mysqld

           Run the mysqld server with valgrind.

       •   --valgrind-mysqltest

           Run the mysqltest and mysql_client_test executables with valgrind.

       •   --valgrind-option=str

           Option to give valgrind. Replaces default option(s). Can be specified more then once&.

       •   --valgrind-path=path

           Path to the valgrind executable.

       •   --vardir=path

           Specify the path where files generated during the test run are stored. The default
           location is ./var. The environment variable MYSQLTEST_VARDIR will be set to the path
           for this directory, whether it has the default value or has been set explicitly. This
           may be referred to in tests.

       •   --verbose

           Give more verbose output regarding test execution. Use the option twice to get even
           more output. Note that the output generated within each test case is not affected.

       •   --verbose-restart

           Write when and why servers are restarted between test cases.

       •   --view-protocol

           Create a view to execute all non updating queries.

       •   --vs-config=config_val

           Visual Studio configuration used to create executables (default: MTR_VS_CONFIG
           environment variable) This option is for Windows only.

       •   --wait-all

           If --start or --start-dirty is used, wait for all servers to exit before termination.
           Otherwise, it will terminate if one (of several) servers is restarted.

       •   --warnings

           Search the server log for errors or warning after each test and report any suspicious
           ones; if any are found, the test will be marked as failed. This is the default
           behavior, it may be turned off with --nowarnings.
