Does not work with MySQL 5.7

[stephankaag]

[dbussink]

Do you have a way to reproduce this just with DO without DataMapper involved? Right now it's not possible to see if the problem is somewhere in DataMapper or on DO.

[stephankaag]

Lots of the MySQL tests in this project are failing under MySQL 5.7.

This may not be exclusive to DO.

However, I do have a project with Padrino & Datamapper and it can't boot due to an error on 'dm-do-adapter', causing a SQL Syntax error just like the OP posted. Perhaps the error comes from that gem.

Any idea where to look @dbussink?

[dbussink]

@stephankaag Not really without looking myself. You mentioned the do_mysql tests failing on 5.7, but I don't have 5.7 setup yet so I'd have to first do that to see what is going on.

[dbussink]

I just tried running the CI suite against 5.7 and it seems to pass without issues. @stephankaag Do you have the output for the failures you saw running the specs for DO?

[stephankaag]

@dbussink Sure. See https://gist.github.com/stephankaag/77dd188b163c2ae4c719

[dbussink]

@stephankaag Do you have additional details of your setup? Like what exact versions are you running? (MySQL, Ruby etc). I haven't been able to reproduce this with 5.7 myself yet so I'm kind of shooting in the dark. Another thing to know is which version do_mysql.dylib is linked to?

[stephankaag]

@dbussink Is there anything I can do to help?

[dbussink]

@stephankaag I've been able to reproduce the problem in a test environment, but haven't had time to further dig into the issue.

[dbussink]

Opened #92 which solves this issue. Plan to release a new version after fixing a few more bugs.

[stephankaag]

Hero! :-)
