hi all,
the first alpha version of SEC-2.7 has been released and is available at
http://sourceforge.net/projects/simple-evcorr/files/sec/2.7.alpha1/sec-2.7.alpha1.tar.gz/download
It has quite many new features, including 14 new actions which allow for
more advanced operations on contexts, but also conditional execution
with if-action and loops with while-action.
PerlFunc patterns have been augmented with an opportunity to set named
match variables. For all pattern types which set match variables,
previously cached matches can be accessed with $:{entry:var} syntax.
Also, context expressions accept the new :> operator for passing
references to pattern match cache entries directly to Perl subroutines.
Not all features which I had in mind or which were discussed in the
mailing list were implemented. In fact, when writing the first alpha
release, I created 3-4 different implementations with different feature
sets enabled, and benchmarked them against larger event volumes. The
testing clearly revealed that some features would decrease the
performance of the tool by 10-15%, and enabling them all would impose a
hard penalty on all users. Therefore I opted a more conservative
approach and implemented only those things which add true value to the
end user without sacrificing performance.
Finally, I'd welcome any help with testing the new alpha release!
with kind regards,
risto
