| | | | | | | | | | | | | backported that was written for the TRE integration project in Google Summer of Code 2011. This is a temporary solution until the whole regex library is not replaced so that BSD grep development can continue and the backported code gets some review and testing. This change only improves scalability slightly, there is no big performance boost yet but several minor bugs have been found and fixed.

Deliverables: Small and clean code (1,4 KSLOC vs GNU's 8,5 KSLOC), lower memory usage than GNU grep, GNU compatibility, BSD license. TODO: Performance is somewhat behind GNU grep but it is only significant for bigger searches. The reason is complex, the most important factor is that GNU grep uses lots of optimizations to improve the speed of the regex library. First, we need a modern regex library (practically by adopting TRE), add support for GNU-style non-standard regexes and then reevalute the performance issues and look for bottlenecks. In the meantime, for those, who need better performance, it is possible to build GNU grep by setting WITH_GNU_GREP.
