Is it possible to force Moodle 2.7 to use Mysql 5.1?

Is it possible to force Moodle 2.7 to use Mysql 5.1?

Hi All,

I know Moodle has a requirement of Mysql 5.5+, but my hosting provider only allow me to use Mysql 5.1. Is it dangerous to force (hardcore) the Mole installer to allow me to install with Mysql 5.1 ? My main concern is if it is going to have unexpected running problems , I mean: do Moodle use specific Mysql 5.5 features that prevent me to use Mysql 5.1?

Thanks!

According to MDL-42931 it seems there was no particular technical reason for requiring 5.5 in Moodle 2.7. It was chosen wisely as 2.7 is the LTS release and Moodle HQ will have to live with declared versions for long time.

On the other hand, MySQL 5.5 has been there for couple of years now and the overall list of improvements is quite huge. Maybe it's time to consider another hosting provider?

Thanks for your answer David. Unfortunately I can't change my provider right now (though I'm starting to hate them glimlach .  I think I'm going to use Moodle 2.6 for now, because my client doesn't have the need to use the latest Moodle features, though I know, as a developer, that it would be the better option (and LTS, what is nicer). Do you think I can have problems if I change the Mysql requirement in the install script to allow me the 5.1 with Moodle 2.7?

As a developer, you must know such question is really hard to answer glimlach If it was me, I would try it.

Yes, if only I could get my host to upgrade too.  Although- in their defense, if there's no major technical changes between 5.1 and 5.5 then why fix what ain't broke?  Or, why would moodle require it?
