I change from `exit;` to `exit(1);` on a function `usage()`.
When we try to run mtr with a wrong option, a function `usage()` is called with the wrong option as its argument. In this case, because the function call `exit` in a first if statement, we get exit status 0.
mtr is checking the wrong path for the embedded executable
on out of tree builds.
The is_embedded.inc tests are also checking the version rather
than the MTR MYSQL_EMBEDDED environment variable.
As a result, a few tests are out of date in the result recordings.
expect file is always removed before starting a server.
So if it exists here, it means the server started successfully,
mysqltest continued executing the test, created a new expect file,
and shut down the server. All while we were waiting for the server
to start.
In other words, if the expect file exists, the server did actually start.
Even if it isn't running now.
This fixes occasional failures of innodb.log_corruption (in 10.6)
* return a success/failure value from mysqld_start()
and don't error out / exit in mysqld_start(), the caller will do
* pass the correct $mysqld object into check_expected_crash_and_restart()
instead of searching for it inside. Search in the caller
* so that when a failed restart changes $mysqld->{proc}, mtr would
still detect it as a failed mysqld (by updating $proc to match)
also: log the server command line into the server error log
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)
"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

- Patch is solving generating report on warning
To repeat the error run single worker:
```
./mtr --mysqld=--lock-wait-timeout=-xx 1st 1st --force --parallel 1
```
or `N` workers with `N+1` tests with failures and `force`
```
./mtr --mysqld=--lock-wait-timeout=-xx 1st 1st grant5 --force --parallel 2
```
- Patch is doing cosmetic fix of `current_test` log file which holds the old log value of test `CURRENT TEST:..` in `mark_log()` in case of `unknown option` and as such
the logic which is using it's content doesn't output valid log content and doesn't generate valid `$test->{'comment'}` message.asdf

- `gdb` option will be added during the merge
1. rr record -h randomizes number of processors. Disable THREAD_POOL_SIZE check.
2. check for kernel.perf_event_paranoid for user-friendly error message.
- Adding optional qualifiers to data types:
CREATE TABLE t1 (a schema.DATE);
Qualifiers now work only for three pre-defined schemas:
mariadb_schema
oracle_schema
maxdb_schema
These schemas are virtual (hard-coded) for now, but may turn into real
databases on disk in the future.
- mariadb_schema.TYPE now always resolves to a true MariaDB data
type TYPE without sql_mode specific translations.
- oracle_schema.DATE translates to MariaDB DATETIME.
- maxdb_schema.TIMESTAMP translates to MariaDB DATETIME.
- Fixing SHOW CREATE TABLE to use a qualifier for a data type TYPE
if the current sql_mode translates TYPE to something else.
The above changes fix the reported problem, so this script:
SET sql_mode=ORACLE;
CREATE TABLE t2 AS SELECT mariadb_date_column FROM t1;
is now replicated as:
SET sql_mode=ORACLE;
CREATE TABLE t2 (mariadb_date_column mariadb_schema.DATE);
and the slave can unambiguously treat DATE as the true MariaDB DATE
without ORACLE specific translation to DATETIME.
Similar,
SET sql_mode=MAXDB;
CREATE TABLE t2 AS SELECT mariadb_timestamp_column FROM t1;
is now replicated as:
SET sql_mode=MAXDB;
CREATE TABLE t2 (mariadb_timestamp_column mariadb_schema.TIMESTAMP);
so the slave treats TIMESTAMP as the true MariaDB TIMESTAMP
without MAXDB specific translation to DATETIME.
There was no ability to set the mtr arguments of:
* --max-save-core; and
* --max-save-datadir
to 0. This is desireable in an automatied scenario where space
is limited hence targeting 10.1 branch.
We take away the 0 means unlimited aspect for these,
however, perl can handle some big numbers so they may as well be
close enough to unlimited for all meaningful purposes.
On FreeBSD, perl isn't in /usr/bin, its in /usr/local/bin or
elsewhere in the path.
Like storage/{maria/unittest/,}ma_test_* , we use /usr/bin/env to
find perl and run it.
This feature adds the support for rr in mtr. These 2 options are added
--rr run the mysqld in rr record mode
--rr_option= run the rr with custom record option, for multiple
options use --rr_option= for each option.
For example
./mtr main.view --rr_option=-h --rr_option=-u --rr_option=-c=23
--boot-rr run the mysqld performing bootstrap in rr record mode
Recording are stored in mysql-test/var/rr folder.
To run recording please run
rr replay var/rr/mysql-X
Limitations
Restart will create a new recording.
Repeat will work on same recording , So might be harder to debug.
If test create the multiple instance of mariadb all will be stored in var/rr
