69989 - javascript search function does not support regular expressions.

Status: VERIFIED WORKSFORME

(Core :: JavaScript Engine, defect)

Description

[Stephen Ostermiller]

The url I noticed this with is in a password protected management utility.  I'll
attach a simplified test case.  Both IE and Netscape 4 deal fine with the test
case.  Mozilla does not.

Attachment: testcase - Mozilla will not recognize valid host names.

Bug confirmed in windows (build 2001021304). Changing OS to all.

Comment 3

The issue here is the (foo)+$ construct.  Note that a domain name like foo.bar
is correctly identified as valid.

There is a fix for this problem currently being reviewed.

Verified Duplicate. Stephen's test has been added to the existing
regression test for bug 67773:

             js/tests/ecma_3/RegExp/regress-67773.js


His test has been added as follows:

             pattern = /^[A-Za-z0-9]+((\.|-)[A-Za-z0-9]+)+$/;
             string = 'some.host.tld';
             actualmatch = string.match(pattern);
             expectedmatch = Array(string, '.tld', '.'); 


The expectedmatch array = what you get in Perl, and in NN4.7 ...

The fix for bug 67773 did not fix this bug.
The testcase still fails. (Build ID: 2001030813 Linux)

I just can't read what the alert box actually says.  Please ignore me. It does work.

Marking Verified Fixed. 

Stephen's HTML testcase passes using Mozilla nightly 2001031204 WinNT.

Also, testcase js/tests/ecma_3/RegExp/regress-67773.js 
passes in the standalone JS shell on Linux and WinNT -
