Fixed #15954 - New IGNORABLE_404_URLS setting that allows more powerful filtering of 404s to ignore

Browse Source 
Thanks to aaugustin for implementing this.

(Technically this doesn't fix the original report, as we've decided against
having *any* default values, but the new feature makes it possible, and the
docs have an example addressing #15954).

`IGNORABLE_404_STARTS` and `IGNORABLE_404_ENDS` settings
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Django can report 404 errors: see :doc:`/howto/error-reporting`.
Until Django 1.3, it was possible to exclude some URLs from the reporting
by adding prefixes to :setting:`IGNORABLE_404_STARTS` and suffixes to
:setting:`IGNORABLE_404_ENDS`.
In Django 1.4, these two settings are superseded by
:setting:`IGNORABLE_404_URLS`, which is a list of compiled regular expressions.
Django won't send an email for 404 errors on URLs that match any of them.
Furthermore, the previous settings had some rather arbitrary default values::
IGNORABLE_404_STARTS = ('/cgi-bin/', '/_vti_bin', '/_vti_inf')
IGNORABLE_404_ENDS = ('mail.pl', 'mailform.pl', 'mail.cgi', 'mailform.cgi',
'favicon.ico', '.php')
It's not Django's role to decide if your website has a legacy ``/cgi-bin/``
section or a ``favicon.ico``. As a consequence, the default values of
:setting:`IGNORABLE_404_URLS`, :setting:`IGNORABLE_404_STARTS` and
:setting:`IGNORABLE_404_ENDS` are all now empty.
If you have customized :setting:`IGNORABLE_404_STARTS` or
:setting:`IGNORABLE_404_ENDS`, or if you want to keep the old default value,
you should add the following lines in your settings file::
import re
IGNORABLE_404_URLS = (
# for each <prefix> in IGNORABLE_404_STARTS
re.compile(r'^<prefix>'),
# for each <suffix> in IGNORABLE_404_ENDS
re.compile(r'<suffix>$'),
)
Don't forget to escape characters that have a special meaning in a regular
expression.
