#34692 closed defect (bug) (fixed)

Unknown system variable storage_engine when running tests in MySQL 5.7

Reported by: jeremyfelt's profile jeremyfelt Owned by: pento's profile pento
Milestone: 4.5 Priority: normal

The MySQL system variable storage_engine was removed in 5.7 after being deprecated in 5.5. The following error is shown when running our tests with MySQL 5.7:

PHPUnit_Framework_Exception: WordPress database error Unknown system variable 'storage_engine' for query SET storage_engine = INNODB

It looks like we should be able to convert our use to default_storage_engine when setting up WordPress for unit tests.

default_storage_engine was added in MySQL 5.5.3, so this will fail on older MySQL versions.

In 36055:

Tests: Use the default_storage_engine MySQL option on newer MySQL versions.

In MySQL 5.5.3, storage_engine was deprecated in favour of default_storage_engine, and subsequently removed in MySQL 5.7. To avoid errors when running tests on MySQL 5.7, we need to switch between the options based on MySQL version.

Props skithund, jeremyfelt.

Fixes #34692.

@pento If this is backported to 4.4.1, would that mean 4.4.1 would completely support MySQL 5.7?

#7 @pento

4.4 already supports MySQL 5.7, it's just that the tests don't run.

This is not a regression in 4.4, but it is a fairly small change, so I have no strong feelings either way about backporting it to 4.4.1.

Cool beans.
