Eclipse hangs because of complicated regular expression for ConsolePatternMatcher #32

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
* See https://bugs.eclipse.org/bugs/show_bug.cgi?id=175888 for attachment, if 
veloeclipse is installed and some application prints out large text it may hang 
Eclipse. 

This happens while matching the regular expression 
"\S+\.(vm|vsl|vtl|html|xml)\[.+,.+\]" which is used in class 
"PatternMatchListener". The regular expression is so complex that the matching 
never finishes when large text is displayed in the Console window.

What is the expected output? What do you see instead?
* No Eclipse hang

What version of the product are you using? On what operating system?
* Eclipse 3.6, veloeclipse 2.0.8

Yes, I tested it and eclipse hangs on this one too.

(\d+.\d+.\d+.\d+) \[(\d{2}/(.)*/\d{4}:\d{2}:\d{2}:\d{2}) -(\d+)] /| (\w|.)+ \|
 Eclipse 3.6 with RegEx Tester.

Hmm, I'm using 3.7 and it seems to work, maybe they fixed the regex 
functionality.
