Hi Sergei,
Please review a patch that merges a new read-only variables --explicit-defaults-for-timestamp from MySQL.
Note, the original MySQL patch updates many tests, to make the tests independent from the compiled-in default --explicit-defaults-for-timestamp value. I guess Oracle is planning to change the default value to ON eventually. I merged these changes for tests as well.
Okay. I wouldn't do it, but it's your call...
As a result, all tests pass in both "mtr" and "mtr --mysqld=--explicit-defaults-for-timestamp", which I think is good.
I don't care much about it. That is, I don't think it's valuable to spend the time on making tests to pass for all possible initial values of server options.
In addition to the original MySQL changes in mtr, I also added two tests that describe specific behavior: sys_vars.explicit_defaults_for_timestamp_off sys_vars.explicit_defaults_for_timestamp_on
If they're functional tests, their file names typically end with _func. Although it's not that important now, when all_vars tests is disabled. Regards, Sergei
