	* VERSION (_MAKE_VERSION): 20251111
	Merge with NetBSD make, pick up
	o var.c: add :sh1 which only evaluates command on first reference.

	* configure.in: Force filemon=no for Cygwin and MINGW64_NT

2025-11-10  Simon J Gerraty  

	* unit-tests/Makefile: handle MINGW64_NT
	mark some tests broken, filter others as per Cygwin.

2025-10-22  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20251022

	Merge with NetBSD make, pick up
	o var.c: avoid compiler warning from hexdigits

mk/ChangeLog since bmake-20250804

2025-11-18  Simon J Gerraty  

	* sys.vars.mk: set MAKE_POSIX_SHELL to 1 if .SHELL is POSIX, 0 if not.
	set isPOSIX_SHELL for use in target scripts.

	* meta.stage.mk: set MAKE_POSIX_SHELL if needed.

	* install-new.mk: use ${isPOSIX_SHELL:Ufalse} to see if we can
	avoid running 'expr'.

	* install-new.mk: Allow use of cp or mv - controlled by CPMV_OP
	(default mv).

2025-11-13  Simon J Gerraty  

	* sys.vars.mk: add M_sh1 so we can handle older bmake that does
	not support :sh1

2025-11-11  Simon J Gerraty  

	* install-mk (MK_VERSION): 20251111

	* meta2deps.sh: reset some vars for each new meta file
	set meta_file to path of meta file.

2025-09-16  Simon J Gerraty  

	* options.mk: Add OPTIONS_DEFAULT_DEPENDENT_REQUIRED of the form
	OPTION/REQUIRED[/VALUE]
	if OPTION is $VALUE (default is "yes"), then REQUIRED must be too.
	We add OPTIONS_DEFAULT_DEPENDENT_REQUIRED (sans any /{yes,no}) to
	OPTIONS_DEFAULT_DEPENDENT so DEPENDENT/REQUIRED follow the same
	processing.

	Also add OPTIONS_FORCED_VALUES of the form OPTION/{yes,no}
	we add any OPTIONS_FORCED_NO and OPTIONS_FORCED_YES before
	processing.

	Simplify the processing of OPTIONS_DEFAULT_VALUES and
	OPTIONS_DEFAULT_DEPENDENT by splitting the tuples and use two
	iterator variables in the .for loops.

2025-08-09  Simon J Gerraty  

	* install-mk (MK_VERSION): 20250808

	* replace sjg license with just BSD-2-Clause SPDX tag

	* VERSION (_MAKE_VERSION): 20240430
	Merge with NetBSD make, pick up
	o main.c: ensure '.include ' respects MAKESYSPATH.
	Dir_FindFile will search .CURDIR first unless ".DOTLAST" is seen.

2024-04-28  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240428
	Merge with NetBSD make, pick up
	o simplify freeing of lists
	o arch.c: trim pointless comments
	o var.c: delay variable assignments until actually needed
	don't reallocate memory after evaluating an expression, result is
	almost always short-lived.

2024-04-26  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240426
	Merge with NetBSD make, pick up
	o job.c: in debug output, print the directory in which a job
	failed at same time as failed target so it is more easily found in
	build log.

2024-04-24  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240424
	Merge with NetBSD make, pick up
	o clean up comments, code and tests

2024-04-23  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240422
	Merge with NetBSD make, pick up
	o var.c: avoid LazyBuf for :*time modifiers.
	LazyBuf's are not nul terminated so not suitable for passing to
	functions that expect that. These modifiers are used sparingly so
	an extra allocation is not a problem.

2024-04-20  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20240420
	Merge with NetBSD make, pick up

	Merge with NetBSD make, pick up

	o uname -s output isn't useful so allow configure to
	set FORCE_MAKE_OS - to force the value of .MAKE.OS
	and use Cygwin which matches uname -o
	o fix some unit-tests for Cygwin

	* configure.in: use_makefile=no for Cygwin et al.
	NOTE: bmake does not support Cygwin and likely never will,

mk/ChangeLog since bmake-20240309

2024-04-24  Simon J Gerraty  

	* meta.autodep.mk: do not override start_utc

2024-04-18  Simon J Gerraty  

	* sys.dirdeps.mk: set defaults for DEP_* at level 0 too.
	These help when first include of Makefile.depend happens in a leaf
	dir.

2024-04-09  Simon J Gerraty  

	* install-mk (MK_VERSION): 20240408

	and Q from QUALIFIED_VAR_LIST and VAR_QUALIFIER_LIST.

	* progs.mk: avoid overlap between PROG_VARS and
	init.mk's QUALIFIED_VAR_LIST since PROG would also
	match its VAR_QUALIFIER_LIST,
	libs.mk does not have the same issue.

	* subdir.mk: _SUBDIRUSE for realinstall should run install
	remove include of ${.CURDIR}/Makefile.inc that can be done via
	local.subdir.mk where needed

2024-03-19  Simon J Gerraty

	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

	INCLUDES, LIBRARIES, POSIX, SYSVINCLUDE, SYSVVARSUB,
	GMAKEEXPORT NO_REGEX and SUNSHCMD

	* 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

	* 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.

Interesting/relevant changes since bmake-20230909

	* VERSION (_MAKE_VERSION): 20240106
	Merge with NetBSD make, pick up
	o fix duplicate progname when reporting an unknown target
	o unit tests for Cmd_Exec using temp file

	* VERSION (_MAKE_VERSION): 20240105
	Merge with NetBSD make, pick up
	o main.c: Cmd_Exec write cmd to a file if too big
	avoid blowing commandline/env limits

	* VERSION (_MAKE_VERSION): 20240101
	o util.c: flesh out more of strftime
	* configure.in: add --with-bmake-strftime
	it is not a full implementation but enough to pass all
	the unit-tests.
	* parse.c: LoadFile do not append \n to empty buffer.

	* VERSION (_MAKE_VERSION): 20231230
	Merge with NetBSD make, pick up
	o simplify memory allocation for string buffers
	o fix declared types of list nodes
	o suff.c: clean up freeing of suffixes
	o var.c: simplify debug message for the ':@var@...@' modifier
	clean up variable handling

	* VERSION (_MAKE_VERSION): 20231226
	Merge with NetBSD make, pick up
	o compat.c: ensure make's output is correctly ordered with that of
	the target when not going to a tty
	o main.c: check for shellPath whether to call Shell_Init()

	* VERSION (_MAKE_VERSION): 20231224
	Merge with NetBSD make, pick up
	o compat.c: check for shellPath whether to call Shell_Init()
	tweak the unit test to detect the bug thus fixed.
	o make.1: do not claim .SHELL is only used by jobs mode.

	* VERSION (_MAKE_VERSION): 20231220
	Merge with NetBSD make, pick up
	o str.c: speed up pattern matching in the ':M' modifier
	o var.c: fix confusing debug logging when deleting a variable
	use consistent debug messages style when ignoring variables

	* VERSION (_MAKE_VERSION): 20231210
	Merge with NetBSD make, pick up
	o var.c: avoid segfault on empty :C match expression
	explain in debug log why variable assignment is ignored.

	* VERSION (_MAKE_VERSION): 20231208
	Merge with NetBSD make, pick up
	o var.c: ensure fromCmd is set correctly for variables set on
	command line.

	* VERSION (_MAKE_VERSION): 20231124
	Merge with NetBSD make, pick up
	o main.c: cleanup processing of -j
	fix lint warning about strchr
	o var.c: more accurate error message for invalid ':mtime' argument
	cleanup :[...] modifier
	avoid reading beyond substring when comparing
	o unit-tests cover all cases of :mtime, test and explain exporting
	of variables
	o cleanup comments

	* bsd.after-import.mk (ECHO_TAG): FreeBSD no longer uses
	$FreeBSD$ tag, so avoid adding it.

mk/ChangeLog since bmake-20230909

	* dirdeps.mk: for MAKE_VERSION 20240105 we do not have the same
	limits on command line length, so skip export of lists to env.

	* jobs.mk: avoid C suffix in JOB_MAX_C if factor is floating
	point.  This keeps JOB_MAX numeric incase another makefile does
	comparisons.

	* gendirdeps.mk: if META_XTRAS is passed to us, add to META_FILES

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-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-20210110

2021-01-14T01:24:34+00:00

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

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.
