ChangeLog since bmake-20250804

2025-11-15  Simon J Gerraty

	to env.out for debugging.

2025-11-12  Simon J Gerraty  

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

2025-11-11  Simon J Gerraty  

	* 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.

2025-10-23  Simon J Gerraty  

	* make.1: document MAKE_VERSION.

2025-10-22  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20251022

	* configure.in: Add a check that lua is version 5.2 or later
	if not we want to skip running check-expect.lua

2025-09-16  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20250916
	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.
	If meta2deps appears in DEBUG_SH set -x.

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

	o show contents of MAKEFLAGS in the stack trace.
	o main.c: delay warning about bogus -J flag, if we end up in
	compat mode before the call to InitMaxJobs, the warning isn't
	necessary.

2025-05-25  Simon J Gerraty  

	* VERSION (_MAKE_VERSION): 20250525
	Merge with NetBSD make, pick up

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.

	o var.c: simplify error handling for unknown modifiers

	the same value.

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

	* VERSION (_MAKE_VERSION): 20240301

	Merge with NetBSD make, pick up

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

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.

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.
