- 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
- Closing the socket/handler after the removing the handler from IO for
consistency

- `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
otherwise it reaches "0 tests left" state and then waits for
a few minutes for all workers to complete their tests.
show failures. account for retries.
This reverts commit c675886dcd.
The bug was introduced in e3f5789ac0 and fixed in 1af74d523a
The option was introduced between those two commits and now it's
redundant again.
