Bug #46865
closed
Email regular expression freezes whole frame in Chrome
0%
Description
When using some long string as link text in the htmlarea editor, the browser window may freeze completely. (in Chrome only, ok in Firefox)
The text used to trigger the problem : "Ministère des Transports du Québec (Direction Saguenay-Lac-Saint-Jean-Chibougamau) et CSST"
I found out that the regex validation to detect email addresses is the cause of this problem.
As a quick patch, in htmlarea.js, line 4369, I replaced :
if (selection.anchorNode.data.match(HTMLArea.RE_email) && (a.href.match('mailto:' + selection.anchorNode.data.trim()))) {
by :
if (selection.anchorNode.data.indexOf('') !== -1 && selection.anchorNode.data.match(HTMLArea.RE_email) && (a.href.match('mailto:' + selection.anchorNode.data.trim()))) {@
This solves the problem for this particular case, but maybe the RE_email regex should be looked upon.

- Write the following text: "Ministère des Transports du Québec (Direction Saguenay-Lac-Saint-Jean-Chibougamau) et CSST"
- Add an external link to this text
- Save record
- Get back to the record and click inside the link text
- Write characters inside the link
Chrome should freeze while entering text.
If you can't reproduce the issue. I'll retry myself with a clean TYPO3 6 instance.

I just tried this again with TYPO3 6.1.2 and Chrome 28.0.1500.72 on Windows 7 and on iOS 6.1.3 without being able to make Chrome freeze.
