Import bmake-20220204 Features of interest: Allow setting target local variables (similar to gmake) In META_MODE .MAKE.META.CMP_FILTER can be used for filtering commands before comparion. contrib/bmake/mk/cc-wrap.mk is an example of using these See ChangeLog for the gory details.

Import bmake-20200517 Changes since 20181221 are mostly portability related hence the large gap in versions imported. There are however some bug fixes, and a rework of filemon handling. In NetBSD make/filemon/filemon_ktrace.c allows use of fktrace and elimination of filemon(4) which has not had the TLC it needs. FreeBSD filemon(4) is in much better shape, so bmake/filemon/filemon_dev.c allows use of that, with a bit less overhead than the ktrace model. Summary of changes from ChangeLog o str.c: empty string does not match % pattern plus unit-test changes o var.c: import handling of old sysV style modifier using '%' o str.c: refactor brk_string o meta.c: meta_oodate, CHECK_VALID_META is too aggressive for CMD a blank command is perfectly valid. o meta.c: meta_oodate, check for corrupted meta file earlier and more often. * meta.c: meta_compat_parent check for USE_FILEMON patch from Soeren Tempel o meta.c: fix compat mode, need to call meta_job_output() o job.c: extra fds for meta mode not needed if using filemon_dev o meta.c: avoid passing NULL to filemon_*() when meta_needed() returns FALSE. o filemon/filemon_{dev,ktrace}.c: allow selection of filemon implementation. filemon_dev.c uses the kernel module while filemon_ktrace.c leverages the fktrace api available in NetBSD. filemon_ktrace.c can hopefully form the basis for adding support for other tracing mechanisms such as strace on Linux. o meta.c: when target is out-of-date per normal make rules record value of .OODATE in meta file. o parse.c: don't pass NULL to realpath(3) some versions cannot handle it. o parse.c: ParseDoDependency: free paths rather than assert plus more unit-tests
