I've just pushed release candidate of PCRE 8.20 into F17. The main feature is voluntary just-in-time compilation of state automaton used to match regular expression. Application needs to enable JIT on compiled pattern by passing PCRE_STUDY_JIT_COMPILE option to pcre_study() function before executing pcre_exec() to find all matches. The JIT brings some initial penalty but even single pcre_exec() can benefit because of repetive matching of unanchored expression on a long data. pcretest(1) tool provides new `-s+' option to enable JIT. See pcrejit(3) for more details. I hope nothig gets broken in rawhide because one needs to request JIT explicitly. OTOH I'm not sure whether SELinux/NX will have some objectives, maybe pax marker will be necessary on libpcre. -- Petr -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
