I'm not able to reproduce, could you write a test case for this?
Updated by Pavel Rosický almost 10 years ago
I forgot, that standard textile formatters unescape html tags before, but this method should handle this anyway. Test case attached.
Original result: error
With patch: returns nil as it should

Hi, this bug is still present, but you can reproduce it only if you use non-redmine custom text formatter which supports html (like ckeditor, markdown/textile formatter escape brackets, so <a> will be &\lt;a&\gt; and the affected regex will not fail).
To avoid that I need to patch this method and gsub! these occurances, which causes unnecessary overhead. Or I can patch the whole method (~140 lines!!! definetely worth to refactor) only because of one character.
Can someone take a look at it again? Patch, test-case and backtrace are already attached.

Could you add test cases for it?

I already did, 7 months ago.
Test case - http://www.redmine.org/attachments/13295/application_helper_test.rb.patch :
def test_should_handle_a_tag_without_attributes
text = '<a>http://example.com</a>'
assert_nil parse_redmine_links(text, nil, nil, nil, true, {})
end
Without patch:
1) Error:
ApplicationHelperTest#test_should_handle_a_tag_without_attributes:

What else can I do?
If you want to test textilizable(), I'll have to include ckeditor and a custom html formatter (plugin). Such tests can't be included in a standard Redmine's test suite.

Could you add dummy formatter?
