Reorganize code in django.db.backends

Currently, database backends are split in modules inconsistently. For example:

  • in the base implementation, most classes are defined in; in actual backends, most classes are in;
  • in the base implementation, BaseDatabaseCreation and BaseDatabaseSchemaEditor have their own modules while other classes are defined in;
  • the postgresql backend has an, other backends don't.

It would be easier to make cross-backend changes if the code was organized consistently.

Considering the size of the classes involved, I think we should put each class it its own module.

We should do this late in the 1.8 release cycle when there is less of a chance we'll need to backport bug fixes to 1.7.x as reorganizing a lot of code like this will make backporting more painful.

That sounds sensible. I'll put it on hold until closer to the release date. Is the timeline for 1.8 online anywhere? A quick search didn't reveal it.

comment:5 Changed 4 years ago by Tim Graham

No, we're at least a month behind on the 1.7 release, so that needs to be finished first.

Keywords: 1.8-alpha added

I'm tagging this ticket 1.8-alpha so we can try to make this change close to that date (currently scheduled for January 12) before we fork stable/1.8.x.

gchp, are you planning to work on this? I can review your patch or take a look at this before 1.8 alpha.

Hey berkerpeksag,
I'm not sure if I'll get time, I don't want to say I will in case I don't. Feel free to assign it to yourself if you like!

There are still a couple large patches that touch these classes that may make it into 1.8 (in particular, PR 3669), so let's hold off a bit longer on this -- I'm thinking after the "feature freeze" on Monday, but before we cut the branch and issue an alpha release.

Considering this is essentially code moving and the test suite is happy, I'd consider this RFC.
