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o meta.c: when target is out-of-date per normal make rules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
bmake ***** This directory contains a port of the BSD make tool (from NetBSD). Since 1993 I have run it on AIX, BSDi, Darwin, FreeBSD, HP-UX, IRIX, Linux, Minix, OSF, Solaris, SunOS and even UTS. Others have run it on many more systems. Currently each release is tested on NetBSD, FreeBSD, Solaris and Linux. Since 2003 bmake switched to a date based version (first was 20030714) which generally represents the date it was last merged with NetBSD's make. Since then, NetBSD's make is imported within a week of any interesting changes, so that bmake tracks it very closely. Building ======== The preferred way to bootstrap bmake is:: ./bmake/boot-strap there are a number of args - most of which get passed to configure, eg. :: ./bmake/boot-strap --prefix=/opt see the boot-strap script for details. For folk that hate to read anything, since 20121212 you can also use the GNU standard process of:: ./configure; make; make install To make much use of bmake you will need the bsd.*.mk macros or my portable *.mk macros which are included with bmake since 20121212 and separately available from http://www.crufty.net/ftp/pub/sjg/mk.tar.gz which will be links to the latest versions. Porting ======= If you encounter a system that bmake does not build or work on *out of the box*, I welcome patches. If you can provide access to a suitable machine - even better.
