SSI - Regular expression parsing

[David Reitter]

Hi,

I'm trying to use some SSI in 7.0.39 using SSIFilter.  The file is parsed, in 
principle, but whenever an IF expression with a certain regular expression is 
encountered, Tomcat seems to stop processing the file and will not return any 
contents after that (for the request).

Example:

My request is:

http://...:8080/amt/file.html?year=234234


The relevant portion of the file is:


QS:




year:



not






The response to the request is the beginning of the file, and then

QS:year=2012

After the "#if", nothing is encountered.
Other IF statements work as expected - this seems to have to do with the 
regular expression.

I have tried a number of variants, including $QUERY_STRING instead of ${...}.
I find no error about this in the logs (I have set debug to 1 for the 
SSIFilter, but I'm not sure if I need to change anything else in logging 
properties.

I tried simpler regular expressions.  The following



Leads to the error below:

java.lang.ClassCastException: 
org.apache.catalina.ssi.ExpressionParseTree$EqualNode cannot be cast to 
org.apache.catalina.ssi.ExpressionParseTree$StringNode

org.apache.catalina.ssi.ExpressionParseTree$CompareNode.compareBranches(ExpressionParseTree.java:353)

org.apache.catalina.ssi.ExpressionParseTree$EqualNode.evaluate(ExpressionParseTree.java:381)

org.apache.catalina.ssi.ExpressionParseTree.evaluateTree(ExpressionParseTree.java:67)

org.apache.catalina.ssi.SSIConditional.evaluateArguments(SSIConditional.java:124)
org.apache.catalina.ssi.SSIConditional.process(SSIConditional.java:50)
org.apache.catalina.ssi.SSIProcessor.process(SSIProcessor.java:160)
org.apache.catalina.ssi.SSIFilter.doFilter(SSIFilter.java:144)


This occurs whenever the regular expression does not contain any parenthesis.  
Is it even recognized/parsed as a regexp?


Is this a bug, or is my syntax off?  I follow 
http://tomcat.apache.org/tomcat-6.0-doc/ssi-howto.html
Any help is appreciated.

Done.  I filed bug report #55176. 
I hope it contains all pertinent information.

Thanks for getting back to me.
