# $NetBSD: Makefile,v 1.4 2011/02/16 01:31:33 joerg Exp $
Add BSD grep to the base system and make it our default grep. 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.

Update BSD grep to the latest development version. It has some code 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.

Add a ${CP} alias for copying files in the build. Some users build FreeBSD as non-root in Perforce workspaces. By default, Perforce sets files read-only unless they're explicitly being edited. As a result, the -f argument must be used to cp in order to override the read-only flag when copying source files to object directories. Bare use of 'cp' should be avoided in the future. Update all current users of 'cp' in the src tree. Reviewed by: emaste MFC after: 1 week Sponsored by: Spectra Logic

bsdgrep(1): Rip out "xmalloc" bits xmalloc was a debug malloc implementation, but the x{malloc,calloc,free} functions default to calling the malloc(3) equivalents. Instead of relying on this malloc shim, we can devise better ways to debug malloc issues that aren't misleading upon initial inspection.
