urlize filter before linebreaks doesn't work correctly

[chinkanga@…]

given:

p = "www.example.com"

in template:

{{ p|linebreaks|urlize }}

Your link will not be urlize'd.

However if given (note the line break):

p = "My test www.example.com
oh boy"

using the same template, in my HTML I get:

<p>My test <a href="http://www.example.com%3Cbr" rel="nofollow">www.example.com<br></a> /&gt;oh boy</p>

It looks like the <br /> is getting broken.

Workaround: switch the order of the filters!

Possible Fixes: Make urlize treat the <br /> nicely. Or consider any angle bracket to be a word boundry (angle brackets aren't valid in URLs anyway, right?)

Urlize should be applied to plain text (as per the documentation), not text that is already HTML. Reversing the order of the filters is the right way to use urlize and linebreaks in conjunction.

One difficulty is that we don't want to break processing of text that looks like `<mailto:foo@…>', which occurs in plain text sometimes. So the meaning of '<' is overloaded is we try to handle plain text and HTML here.

(In [5937]) Clarified that urlize and urlizetrunc should only be applied to plain text. Refs #5202.
