2015-06-16Fixed #24828 -- Allowed migration optimization across AlterFooTogetherMarkus Holtermann
The idea behind this change is, that AlterUniqueTogether, AlterIndexTogether and AlterOrderWithRespectTo can always be moved after an Add/Alter/Rename/RemoveField operation if they don't refer to the respective field and are not empty sets / None. Combined with the optimizations of duplicate AlterUniqueTogether, AlterIndexTogether, and AlterOrderWithRespectTo operations from 128caa1e16ec2627737748f75c8e55600a3df97f, these operations are optimized in a later round of the optimizer. Thanks Tim Graham for the review.

resolution. This removes the concept of equality between operations to guarantee compatilibity with Python 3. Python 3 requires equality to result in identical object hashes. It's impossible to implement a unique hash that preserves equality as operations such as field creation depend on being able to accept arbitrary dicts that cannot be hashed reliably. Thanks Klaas van Schelven for the original patch in 13d613f80011852404198dfafd1f09c0c0ea42e6.
