#23891 closed Cleanup/optimization (fixed)

Revise deprecation / removal timeline for IPAddressField

As initially mentioned in #23861, the IPAddressField will be removed in 1.9. Given the current way of squashing migration files, this probably becomes painful to migrate. A proposal that came up in the linked ticket is to keep a stub field around for a bit longer (maybe 2.0?) that works (as a noop) in migrations (prevents import errors) but throws errors if used outside migrations.

An idea is to move the deprecation warning of IPAddressField to the system checks framework (and suggest doing the same for third-party fields). It could be a Warning in 1.8 (maybe 1.7 too if we want to resolve the issue about not being able to silence warnings in old migrations) and Error in 1.9. I can investigate this approach a bit more if the feedback is positive.

Here is a stub that could be kept around in 1.9 (and longer if necessary) to allow people to migrate away from it.

class IPAddressField(Field):
    def __init__(self, *args, **kwargs):
        kwargs['max_length'] = 15
        super(IPAddressField, self).__init__(*args, **kwargs)

    def deconstruct(self):
        name, path, args, kwargs = super(IPAddressField, self).deconstruct()
        del kwargs['max_length']
        return name, path, args, kwargs

    def get_internal_type(self):
        return 'IPAddressField'

Thanks Markus Holtermann for review.

Actually, it seems rather difficult to backport this to 1.7 and keep the test suite output free of these warnings because call_command() executes system checks (changed in master in 685edab9da89b54e3e0e7bbc1c9f8b33d3f45969). Since PendingDeprecatingWarning is silent by default, I think we should just live with the status quo there. However, if someone wants to attempt the backport, I'll happily commit it.

Removed release note for refs #23891 as the backport proved too difficult.
