mk/ChangeLog since bmake-20250414

2025-05-28  Simon J Gerraty  

	* install-mk (MK_VERSION): 20250528

	* add dirdeps2dplibs.mk

2025-05-18  Simon J Gerraty  

	* install-mk (MK_VERSION): 20250518

	* meta.autodep.mk (META_FILES): re-work to fix filtering.
	if OPTIMIZE_OBJECT_META_FILES==yes
	provide a default META_FILE_OBJ_FILTER that selects a valid
	.SUFFIX to match *o.meta, there's no guarantee that it will be as
	simple as .o or .So etc.
	We have to defer evaluation until the target script is run
	for any of these filters to have any effect.
	Use :S,${.OBJDIR}/,, rather than :T incase there are objects
	in sub-dirs.

	* lib.mk: leverage ${.SUFFIXES} when setting dependencies.

	* add UPDATE_DEPENDFILE as a dependent option - follows
	DIRDEPS_BUILD and use MK_UPDATE_DEPENDFILE as default for
	UPDATE_DEPENDFILE when we think it should be yes.
	This allows override with -DWITH[OUT]_UPDATE_DEPENDFILE
	without overriding UPDATE_DEPENDFILE directly - which can lead to
	trouble.

2025-05-16  Simon J Gerraty  

	* install-mk (MK_VERSION): 20250515

	* meta2deps.py: resolve the target of a Move or Link first
	and track the last path resolved, then if the src is a relative
	path we can easily use that last path to resolve the src correctly.

	* meta2deps.sh: for a Move or Link add the dir of target path to
	the list used to resolve the src path.

	* VERSION (_MAKE_VERSION): 20250125
	Merge with NetBSD make, sync up below change.

	* unit-tests/Makefile: remove $TMPDIR via .END

	* Makefile: use genfiles.mk to generate ${MAN}
	so that it can be tuned for local site.
	Ensure MAN  is defined before including Makefile.inc

	* Makefile: use MK_GEN_MAN to make it easier to control whether we
	generate ${MAN}

2024-09-16  Simon J Gerraty

2024-12-03  Simon J Gerraty  

	* install-mk (MK_VERSION): 20241202

	* setopts.sh: needed by newlog.sh

2024-11-22  Simon J Gerraty

	easier to add things like 'env' when debugging.

	* install-mk (MK_VERSION): 20241122

	* rust.mk: rename CARGO* to RUST_CARGO* so I don't feel
	like this makefile should be renamed to cargo.mk

2024-11-11  Simon J Gerraty  

	* dirdeps.mk: add DIRDEPS_CACHED_ENV to dirdeps-cached and
	DIRDEP_USE_EPILOGUE to _DIRDEP_USE

2024-10-30  Simon J Gerraty  

	* meta.sys.mk: if MK_META_ERROR_TARGET is yes and NEWLOG_SH is
	set, and ERROR_LOGDIR already exists, hook _rotateErrorLog to
	.BEGIN target.

2024-10-27  Simon J Gerraty  

	* options.mk: add support for DEBUG_OPTIONS (similar to
	DEBUG_DIRDEPS) to allow us to see where options get set.
	Eg. DEBUG_OPTIONS="STAGING*" gives:

	bmake[1]: "mk/options.mk" line 89: sys.mk: MK_STAGING=yes (MK_DIRDEPS_BUILD=no)

	Makefile.depend file, always report what the actual makefile is
	with the DIRDEP it is for.
	Remove the redundant "Looking" message.

2024-09-26  Simon J Gerraty  

	* meta2deps.py: when raising AssertionError include meta file name
	with $SB trimmed if possible.

2024-09-23  Simon J Gerraty  

	* meta2deps.py: replace assert() with raise AssertionError when we
	detect missing eXits, to ensure a meaningful message gets into
	log.

ChangeLog since bmake-20240108

2024-03-10  Simon J Gerraty  

	* boot-strap: tests can take a long time; use a cookie to
	skip them if bmake has not been updated since tests last
	ran successfully.

	* Makefile: Cygwin handles MANTARGET man

	* unit-tests/Makefile: set BROKEN_TESTS for Cygwin

2024-03-09  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240309
	Merge with NetBSD make, pick up
	o set .ERROR_EXIT to the exit status of .ERROR_TARGET
	this allows a .ERROR target to ignore the case of
	.ERROR_EXIT==6 which just means that the build actually
	failed somewhere else.

2024-03-04  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240303

	* var.c: on IRIX we need both inttypes.h and stdint.h

2024-03-01  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240301
	Merge with NetBSD make, pick up
	o export variables with value from target scope
	when appropriate.

2024-02-12  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240212
	Merge with NetBSD make, pick up
	o remove unneeded conditional-compilation toggles
	INCLUDES, LIBRARIES, POSIX, SYSVINCLUDE, SYSVVARSUB,
	GMAKEEXPORT NO_REGEX and SUNSHCMD

	* configure.in: add check for regex.h

	* var.c: replace use of NO_REGEX with HAVE_REGEX_H

2024-02-04  Simon J Gerraty

2024-03-09  Simon J Gerraty  

	* install-mk (MK_VERSION): 20240309

	* meta.sys.mk: _metaError: if .ERROR_EXIT == 6, we do not
	want to save the .ERROR_META_FILE

2024-02-20  Simon J Gerraty  

	* install-mk (MK_VERSION): 20240220

	* sys.dirdeps.mk, dirdeps-targets.mk, init.mk:
	do not set .MAIN: dirdeps in sys.dirdeps.mk
	dirdeps-targets.mk will do that for top-level builds
	and init.mk will do it for others.
	This allows a Makefile which has no need of 'dirdeps' to
	set .MAIN for itself and "just work".

2024-02-18  Simon J Gerraty  

	* bsd.*.mk: for makefiles that get a bsd. symlink,
	use _this in  multiple inclusion tags since .PARSEFILE will not
	DTRT when such a makefile is included directly by Makefile and
	automatically (without bsd. prefix).
	Since we cannot guarantee that our sys.mk will be used, we provide
	a default _this in each makefile that gets a bsd. prefix such that
	the value is the same regardless of bsd. prefix.

	* subdir.mk: drop the !target guard on $SUBDIR_TARGETS

2024-02-12  Simon J Gerraty  

	* install-mk (MK_VERSION): 20240212

	* SPDX-License-Identifier: BSD-2-Clause
	Add SPDX-License-Identifier to inidicate that I consider
	my copyright on any of these makefiles equivalent to BSD-2-Clause

	* autoconf.mk: allow for configure.ac as currently recommended

	* subdir.mk: support @auto
	which is replaced with each subdir that
	has a [Mm]akefile.

	* subdir.mk: include local.subdir.mk if it exists.

	* subdir.mk: rework to handle .WAIT

2024-02-11  Simon J Gerraty  

	* subdir.mk: _SUBDIRUSE report the target we are entering subdirs for.

2024-02-10  Simon J Gerraty  

	* prog.mk: treat empty SRCS the same as undefined

2024-02-02  Simon J Gerraty  

	* Avoid undefined errors in lint (-dL) mode

	* man.mk (CMT2DOC_FLAGS): note that -mm does mdoc(7)

2024-01-28  Simon J Gerraty  

	* install-mk (MK_VERSION): 20240128

	* FILES: add ccm.dep.mk for C++ modules
	add suffixes.mk for common location for generic SUFFIX rules.

	* auto.dep.mk autodep.mk meta.autodep.mk: include ccm.dep.mk
	replace OBJ_EXTENSIONS with OBJ_SUFFIXES

	* autodep.mk: leverage CXX_SUFFIXES for __depsrcs
	and update style (spaces around = etc)

	* init.mk: add OBJS_SRCS_FILTER to filter SRCS when
	setting OBJS

	* meta2deps.py: handle multiple ./ embedded in path better.

	* unit-tests/Makefile: addd varmod-localtime to BROKEN_TESTS
	if configure cannot work out how to control TZ.
	Remove varmod-localtime from BROKEN_TESTS for IRIX*

2023-07-24  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20230723

	* configure.in: fix the test for wether TZ=Europe/Berlin works.
	Depending on the time of year, if run between 22:00 and 00:00 UTC
	the check in configure would fail incorrectly.
	Take the day into account as well.

2023-07-18  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20230711
	Merge with NetBSD make, pick up
	o make.1: clean up wording, clarify scope of '!' in conditions

2023-07-15  Simon J Gerraty  

	* make-bootstrap.sh.in: set prefix
	If configure is run using ksh we get unexpanded ${prefix} in
	DEFAULT_SYS_PATH, by ensuring prefix is set we should still get
	correct result.

2023-07-13  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20230711
	bump version for IRIX tweaks

	* make.h: undef OP_NONE if defined

	* unit-tests/Makefile: set BROKEN_TESTS for IRIX

	* configure.in: override INSTALL on IRIX

2023-06-27  Simon J Gerraty  

	* boot-strap op_test: ensure we set TEST_MAKE as we want it.

mk/ChangeLog since bmake-20230622

2023-09-09  Simon J Gerraty  

	* jobs.mk (JOB_MAX): use -jC if we can
	we actually use JOB_MAX_C which defaults to 1.33C

2023-08-18  Simon J Gerraty  

	* now_utc: %s only works with :localtime

2023-07-14  Simon J Gerraty  

	* install-sh: ignore -c as claimed and only insist on
	a directory for destination when more than one file to copy.

	* sys.mk: when looking for SYS_OS_MK try ${.MAKE.OS} and
	${.MAKE.OS:S,64,,} early (so we find sys/IRIX.mk for IRIX64)

2023-07-13  Simon J Gerraty  

	* install-mk (MK_VERSION): 20230711

	* sys.mk: set SYS_MK and INSTALL_SH for systems with incompatible
	install(1)

	* sys/IRIX.mk:  when setting ROOT_GROUP only match the first :0:
	set INSTALL to install-sh rather than pathname that may not exist
	(yet).

2023-07-07  Simon J Gerraty  

	* dirdeps.mk: pass DIRDEP_TARGETS to DIRDEP_MAKE
	normally this is empty - for the default target, but there are
	use-cases where we might set it to something else.

2023-07-04  Simon J Gerraty  

	* install-mk (MK_VERSION): 20230704

	* dirdeps.mk: apply DEBUG_DIRDEPS_LIST_FILTER to lists we output
	when DEBUG_DIRDEPS is in effect.
	Eg. DEBUG_DIRDEPS_LIST_FILTER=ts\n
	can greatly improve readability.

2023-04-24T23:44:30+00:00

Relevant/interesting changes:

	* make.1: document seemingly unexplained Error code 6.
	o compat.c: CompatDeleteTarget skip .PHONY targets to be
	consistent with JobDeleteTarget.
	o job.c: fix memory leak in handling sysv :from=to modifiers
	o unit tests for .MAKE.META.IGNORE_{FILTER,PATHS,PATTERNS}
	o var.c: fix parsing of unevaluated subexpressions with
	unbalanced '{}'
	o cond.c: reduce complexity of evaluating expressions

Import bmake-20211212

2021-12-18T07:27:22+00:00

Relevant changes see ChangeLog for details:

Add support for ${.SUFFIXES} as read-only variable.

Fix memory leak in cond.c

Punt on write errors - ENOSPC etc.

Lots of code refactoring, rework to reduce memory allocations.

More unit-tests.

Import bmake-20200902

2020-09-05T16:11:04+00:00

Lots of code refactoring, simplification and cleanup.
Lots of new unit-tests providing much higher code coverage.
All courtesy of rillig at netbsd.

Other significant changes:

o new read-only variable .SHELL which provides the path of the shell
  used to run scripts (as defined by  the .SHELL target).

o new debug option -dl: LINT mode, does the equivalent of := for all
  variable assignments so that file and line number are reported for
  variable parse errors.

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
