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.

/* $NetBSD: filemon.h,v 1.6 2021/12/15 12:08:25 rillig Exp $ */
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 o meta.c: when target is out-of-date per normal make rules record value of .OODATE in meta file.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

Import bmake-20210206 Changes of interest o unit-tests: use private TMPDIR to avoid errors from other users o avoid strdup in mkTempFile o always use vfork o job.c: do not create empty shell files in jobs mode reduce unnecessary calls to waitpid o cond.c: fix debug output for comparison operators in conditionals

Import bmake-20201101 Lots of new unit-tests increase code coverage. Lots of refactoring, cleanup and simlpification to reduce code size. Fixes for Bug 223564 and 245807 Updates to dirdeps.mk and meta2deps.py

#ifndef MAKE_FILEMON_H
Import bmake-20210110 Quite a lot of churn on style, but lots of good work refactoring complicated functions and lots more unit-tests. Thanks mostly to rillig at NetBSD Some interesting entries from ChangeLog o .MAKE.{UID,GID} represent uid and gid running make. o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable checks in InitObjdir. Explicit .OBJDIR target always allows read-only directory. o add more unit tests for META MODE Change-Id: I4d3bcf08b4c864d98b343f602efe5a75dbfa7a94
