django.forms.fields.email_re doesn't handle single-letter subdomains

Reported by: Gumnos Owned by: Daniel Gonzalez Gasull
Component: Forms Version: dev
Severity: Keywords: email_re subdomain speed single letter
Cc: Jason Yosinski Triage Stage: Accepted
Has patch: yes Needs documentation: no

Description

When domain-validating logic was moved from validators to forms.fields.email_re single-letter sub-domains are no longer caught. There were also some speed issues when processing longer email addresses that were resolved in 1.1.1 and 1.0.4 that this patch should also address in a similar manner. There may be a similar issue with forms.fields.url_re but I didn't get a chance to hack that too.

This may conflict with r11603 but should resolve the same email_re issue there.

It also looks like this may be a semi-regression. Tickets #1275 and #1288 regarding the same issue are closed as fixed in r2367 but that looks like it was before some (newforms?) refactor.

It isn't clear if this ticket refers to 2nd level or 3rd level domains. Also, it isn't clear if with "caught" it means single-letter subdomains should be valid or rejected. In any case:

Single-letter 2nd level domains are valid:
http://en.wikipedia.org/wiki/Single-letter_second-level_domain#Active_single-letter_domains

Single-letter 3rd level domains are valid too: #1275

In both cases, Django forms is working as expected. Please see attached diff for tests.
