Comment (by carljm):
Please don't reopen tickets closed wontfix by a core committer just "to
get a second opinion"; that's against our documented policy, as it leads
to too many open/close wars. The right course of action is to raise the
question on the django-developers mailing list.
I'm not sure if this should have been fixed in 1.7 or not. We're still
ironing out some issues with the base initial migrations shipped with the
contrib apps, so I think it's advisable to be cautious in shipping out new
migrations. The 30-character limit has been around for 10 years, another
year plus or minus isn't the end of the world.
That said, I do think that the overly-restrictive max-lengths in the
default user model should be fixed, custom-user-models notwithstanding,
and that built-in migrations should make it possible to fix. Russell, it
sounds like you agree, at least in theory? Could we reflect that consensus
by reopening this ticket?
It occurs to me that custom user models may actually prove an obstacle to
fixing this in a much more direct way, in that fixing it will likely
change the abstract base models that many custom user models are
inheriting from, and we can't ship a migration to change someone's custom
user model. I guess if we start to allow shadowing of fields on abstract
bases, as has been discussed recently on the mailing list, we could make
this change only on the final concrete User model, and leave the abstract
bases alone, for backwards-compatibility. But then future custom user
models inheriting from those bases won't benefit from the change...
