Until https://github.com/rr-debugger/rr/issues/2613
has been addressed, ./mtr --rr will fail to start up the
server if it has been configured with liburing.
To make the ./mtr --rr option work out of the box, we will
disable native asynchronous I/O.
Note: libaio never worked under rr, but it failed more gracefully:
the emulated io_setup() call would always return an error.
use _RR_TRACE_DIR=dir instead of -o dir, as the former can store
multiple traces in dir (if, e.g., the test restarts mysqld)
suppress uninitialized warning when $exe is undefined (--manual-XXX)
add a new "debugger" to mtr, that runs the executable
under valgrind in gdb. valgrind pid is auto-detected,
but the delay (sleep) and vgdb path are hard-coded for now
"debugger" is anything that wraps execution of a target
binary (mysqld or mysqltest). Currently the list includes:
gdb, ddd, dbx, lldb, valgrind, strace, ktrace, rr,
devenv, windbg, vsjitdebugger.
for every debugger xxx, mtr will recognize four options:
--xxx, --boot-xxx, --manual-xxx, --client-xxx.
They all support an optional "=string" argument. String
being a semicolon-separated list of commands (e.g. for gdb)
or one (not semicolon-separated) command line of options
(e.g. for valgrind). Or both (e.g. --gdb='-quiet -nh;info files'
In embedded both --xxx and --client-xxx work.
Functionality changed/removed:
* --rr-args is gone
* --rr-dir is gone
* --manual-debug is gone
* --debugger={devenv|vc|windbg|vc_express|vsjitdebugger} is gone
* --strace-option is gone
* --stracer={strace|ktrace} is gone
* --valgrind only enables it for the server, not for everything
* --valgrind-all is gone
* --valgrind-mysqltest is gone
* --valgrind-mysqld is gone
* --valgrind-options is gone
* --valgrind-option is gone
* --valgrind-path is gone
* --callgrind is gone
* one cannot combine --valgrind --gdb anymore
* valgrind report doesn't add a fake test line to the output
* vc and vcexpress on windows are no longer supported
* use the environment variable HA_S3_SO, not a literal ha_s3 in cnf files
* make ConfigFactory to support empty option values
* update no_s3.result after MDEV-11412
In main.index_merge_myisam we remove the test that was added in
commit a2d24def8c because
it duplicates the test case that was added in
commit 5af12e4635.
When testing installed packages, the client (mariadb or mysql) can have
plugins stored in a separate location compared to server. This change
ensures that the correct paths are used for the plugin-dir directive in
the my.cnf generated by mysql-test-run.
The directives in my.cnf will be replaced like so:
[client]
plugin-dir=$client_plugindir
[mysqld]
plugin-dir=$plugindir
where $<variable-name> corresponds to the variable name in mtr.
A new parameter has been added called xml-report, with which the
filename of the XML file is given to which the XML result is
written. There is also xml-package for adding a package value in
the XML output. Example usage:
./mysql-test-run.pl main.events_bugs innodb.count_distinct
main.explain_json innodb.file_format_defaults json.json_no_table
--suite=main,innodb,json --force --xml-report=build123456789.xml
--xml-package=simpletestrun
