pcre2: import pcre2 from packages feed
pcre2 is needed by newer selinux versions, so it needs to be in the base
repository.

However, it comes at the cost of extra + processing before the match is performed, so it is of most benefit when + the same pattern is going to be matched many times. This does not + necessarily mean many calls of a matching function; if the pattern is + not anchored, matching attempts may take place many times at various + positions in the subject, even for a single call. Therefore, if the + subject string is very long, it may still pay to use JIT even for + one-off matches. JIT support is available for all of the 8-bit, 16-bit + and 32-bit PCRE2 libraries and adds about 100KB to the resulting + libpcre2.so. JIT support applies only to the traditional Perl-compatible + matching function. It does not apply when the DFA matching function is + being used. + + Enabling this option can give an about 10x performance increase on JIT + operations. It can be desireable for e.g. high performance Apache + mod_rewrite or HA-Proxy reqrep operations. + + However, JIT should _only_ be enabled on architectures that are supported. + Enabling JIT on unsupported platforms will result in a compilation + failure. A list of supported architectures can be found here: + https://pcre.org/current/doc/html/pcre2jit.html#SEC2 |
