#32298 closed Cleanup/optimization (fixed)

django.core.validators.URLValidator tests netloc instead of hostname for length

Description

This code: https://github.com/django/django/blob/master/django/core/validators.py#L141

urlparse: https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlparse

In case of url like

urlparse('https://username1:password1@example.com/foo')

the parse result is:

 ParseResult(scheme='https', netloc='username1:password1@example.com', path='/foo', params='', query='', fragment='')

with the username and password in netloc.

Of course if the netloc is too long only because of the password, this causes a valid URL to be not accepted.

The test for length is a requirement for the hostname, so it should test .hostname instead of .netloc

This ticket is not ready for checkin (see Triage stages). Also you shouldn't mark your own patches as ready for checkin.

Replying to Mariusz Felisiak:

This ticket is not ready for checkin (see Triage stages). Also you shouldn't mark your own patches as ready for checkin.

I am sorry, I did not understand the terminology correctly. Thankyou for your correction.

Hello, Can someone help me in progressing this patch. I have submitted a patch which has passed all the build tests. I will also like to write tests for this bug.

comment:7 by Claude Paroz, 4 years ago

The next step is to write a test, you may need to explore a bit the tests folder of Django to find out where other URL validation tests are located.

Added test of this case to

tests/validators/tests.py

where all other url validation tests are present and committed changes to same pull request. https://github.com/django/django/pull/13811.

In b41d38a:

Fixed #32298 -- Fixed URLValidator hostname length validation.

URLValidator now validates the maximum length of a hostname without
the userinfo and port.
