The regular expression for
[https://docs.djangoproject.com/en/1.8/ref/validators/#urlvalidator
URLValidator] accepts consecutive periods as valid. This bug was
introduced in 1.8.3.
== Steps to Reproduce ==
{{{
#!python
>>> from django.core.validators import URLValidator
>>> validate = URLValidator()
>>> validate('http://example..com')
>>> validate('http://example...............com')
}}}
== Expected Result ==
A [https://docs.djangoproject.com/en/1.8/ref/exceptions/#validationerror
ValidationError] exception should be raised.
== Current Result ==
No exception is raised, and the URL is deemed valid.
== Reference ==
[https://tools.ietf.org/html/rfc2181#section-11 RFC 2181]:
The length of any one label is limited to between 1 and 63 octets. A
full domain name is limited to 255 octets (including the separators). The
zero length full name is defined as representing the root of the DNS
tree, and is typically written and displayed as ".".
