ChangeLog since bmake-20240309
2024-04-30 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240430
Merge with NetBSD make, pick up
o main.c: ensure '.include <makefile>' respects MAKESYSPATH.
Dir_FindFile will search .CURDIR first unless ".DOTLAST" is seen.
2024-04-28 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240424
Merge with NetBSD make, pick up
o clean up comments, code and tests
2024-04-23 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240420
Merge with NetBSD make, pick up
o provide more context information for parse/evaluate errors
2024-04-14 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240414
Merge with NetBSD make, pick up
o parse.c: print -dp debug info earlier so we see which
.if or .for line is being parsed.
2024-04-04 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240404
Merge with NetBSD make, pick up
o fix some unit tests for Cygwin
o parse.c: exit immediately after reading a null byte from a makefile
* fix generation of bmake.cat1
2024-03-19 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240314
Add/Improve support for Cygwin
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 <sjg@beast.crufty.net>
* meta.autodep.mk: do not override start_utc
2024-04-18 Simon J Gerraty <sjg@beast.crufty.net>
* sys.dirdeps.mk: set defaults for DEP_* at level 0 too.
These help when first include of Makefile.depend happens in a leaf
dir.
* install-mk (MK_VERSION): 20240414
2024-04-09 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240408
* init.mk: allow for _ as well as . to join V
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
* own.mk: do not conflict with man.mk
2024-03-19 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240314
* add sys/Cygwin.mk from Christian Franke

ChangeLog since bmake-20240108
2024-03-10 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240303
* var.c: on IRIX we need both inttypes.h and stdint.h
2024-03-01 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240204
Merge with NetBSD make, pick up
o var.c: fix some lint (-dL) mode parsing issues
2024-02-02 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION: (_MAKE_VERSION): 20240202
Merge with NetBSD make, pick up
o make.1: note that arg to :D and :U can be empty
o var.c: $$ is not a parse error when .MAKE.SAVE_DOLLARS=no
mk/ChangeLog since bmake-20240108
2024-03-09 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 $SUBDIR_TARGETS
2024-02-12 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240212
* SPDX-License-Identifier: BSD-2-Clause
Add SPDX-License-Identifier to inidicate that I consider
my copyright on any of these makefiles equivalent to BSD-2-Clause
* autoconf.mk: allow for configure.ac as currently recommended
* subdir.mk: support @auto
which is replaced with each subdir that
has a [Mm]akefile.
* subdir.mk: include local.subdir.mk if it exists.
* subdir.mk: rework to handle .WAIT
2024-02-11 Simon J Gerraty <sjg@beast.crufty.net>
* subdir.mk: _SUBDIRUSE report the target we are entering subdirs for.
2024-02-10 Simon J Gerraty <sjg@beast.crufty.net>
* prog.mk: treat empty SRCS the same as undefined
2024-02-02 Simon J Gerraty <sjg@beast.crufty.net>
* Avoid undefined errors in lint (-dL) mode
* man.mk (CMT2DOC_FLAGS): note that -mm does mdoc(7)
2024-01-28 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240128
* FILES: add ccm.dep.mk for C++ modules
add suffixes.mk for common location for generic SUFFIX rules.
* auto.dep.mk autodep.mk meta.autodep.mk: include ccm.dep.mk
replace OBJ_EXTENSIONS with OBJ_SUFFIXES
* autodep.mk: leverage CXX_SUFFIXES for __depsrcs
and update style (spaces around = etc)
* init.mk: add OBJS_SRCS_FILTER to filter SRCS when
setting OBJS
* meta2deps.py: handle multiple ./ embedded in path better.
Relevant/interesting changes:
o optimize string matching for ':M' and ':N'
o warn about malformed patterns in ':M', ':N' and '.if make(...)'
o allow guards to be targets as well as variables
The guard targets may include variable references like
__${.PARSEDIR:tA}/${.PARSEFILE}__
o optimization for makefiles protected from multiple-inclusion
skip even opening the file after first include.
o var.c: do not allow delete of readOnly variable
o parse.c: .break takes no args
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
ChangeLog since bmake-20230126
* VERSION (_MAKE_VERSION): 20230208
Merge with NetBSD make, pick up
o var.c: always use SCOPE_GLOBAL for :_ to avoid problems
when it has been used within conditional expressions
* install-sh: if making directories ensure umask is set
to match mode.
* Makefile: use DIRMODE for directories and
NONBINMODE for man pages and mk files
Relevant/interesting changes (see ChangeLog for more):
o variables like .newline and .MAKE.{GID,PID,PPID,UID}
should be read-only.
o .[NO]READONLY: for control of read-only variables
o .SYSPATH: for controlling the path searched for makefiles
o allow for white-space between command specifiers @+-
o add more details to warning 'Extra targets ignored'
o make.1: sync list of built-in variables with reality
sort list of built-in variables
o cond.c: add more details to error message for numeric comparison
o job.c: fix handling of null bytes in output
o Allow .break to terminate a .for loop early
o var.c: fix out-of-bounds errors when parsing
o fix exit status for '-q' (since 1994)
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.
o allow env var MAKE_OBJDIR_CHECK_WRITABLE=no to skip writable
checks in InitObjdir. Explicit .OBJDIR target always allows
read-only directory.
o Fix building and unit-tests on non-BSD.
o More code cleanup and refactoring.
o More unit tests
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
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
From ChangeLog
2017-10-28 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION: 20171028
Merge with NetBSD make, pick up
o main.c: ignore empty MAKEOBJDIR
* Makefile.config.in:
make @prefix@ @machine*@ and @default_sys_path@ defaults.
2017-10-05 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION: 20171005
* unit-tests/dotwait.mk: redirect stderr through pipe for more
consistent result on some platforms.
2017-08-13 Simon J. Gerraty <sjg@bad.crufty.net>
* machine.sh: entry for AIX
2017-08-12 Simon J. Gerraty <sjg@bad.crufty.net>
* VERSION (_MAKE_VERSION): Move the setting of _MAKE_VERSION
to a file that can be included by configure as well as make.
This allows configure to set set _MAKE_VERSION in make-bootstrap.sh
2017-08-10 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20170810
Merge with NetBSD make, pick up
o meta.c: if target is in subdir we only need subdir name in
meta_name.
Several misc cleanups, refactor main() to reduce size.
Adds -v option to always fully expand variables (only interesting to NetBSD)
And in particular (from ChangeLog):
o meta.c: ensure command output in meta file has ending newline
even when filemon not being used.
When matching ${.MAKE.META.IGNORE_PATTERNS} do not use
pathname via ':L' since any ':' in pathname breaks that.
Instead set a '${.p.}' to pathname in the target context and
use that.

2016-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161212
Merge with NetBSD make, pick up
o main.c: look for obj.${MACHINE}-${MACHINE_ARCH} too.
2016-12-09 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161209
Merge with NetBSD make, pick up
o main.c: cleanup setting of .OBJDIR
o parse.c: avoid coredump from (var)=val
2016-11-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20161126
Merge with NetBSD make, pick up
o make.c: Make_OODate: report src node name if path not set
2016-09-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile (_MAKE_VERSION): 20160926
Merge with NetBSD make, pick up
o support for .DELETE_ON_ERROR: (remove targets that fail)
2016-09-26 Simon J. Gerraty <sjg@bad.crufty.net>
* Makefile MAN: tweak .Dt to match ${PROG}
mk/ChangeLog
2016-12-12 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161212
* meta2deps.py: set pid_cwd[pid] when we process 'C'hdir,
rather than when we detect pid change.
2016-12-07 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161207
* meta.stage.mk: add stage_as_and_symlink for staging packages.
We build foo.tgz stage_as foo-${VERSION}.tgz but want to be able
to use foo.tgz to reference the latest staged version - so we
make foo.tgz a symlink to it.
Using a target to do both operations ensures we stay in sync.
2016-11-26 Simon J. Gerraty <sjg@bad.crufty.net>
* install-mk (MK_VERSION): 20161126
* dirdeps.mk: set DIRDEPS_CACHE before we include local.dirdeps.mk
so it can add dependencies.
2016-10-10 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: set DEP_* before we expand .MAKE.DEPENDFILE_PREFERENCE
do that they can influence the result correctly.
* dirdeps.mk (${DIRDEPS_CACHE}): make sure we pass on TARGET_SPEC
* dirdeps.mk: Add ONLY_TARGET_SPEC_LIST and NOT_TARGET_SPEC_LIST
similar to ONLY_MACHINE_LIST and NOT_MACHINE_LIST
2016-10-05 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: remove dependence on jot (normal situations anyway).
Before we read another Makefile.depend* set DEP_* vars from
_DEP_TARGET_SPEC in case it uses any of them with :=
When bootstrapping, trim any ,* from extention of chosen _src
Makefile.depend* to get the machine value we subst for.
2016-09-30 Simon J. Gerraty <sjg@bad.crufty.net>
* dirdeps.mk: use TARGET_SPEC_VARS to qualify components added to
DEP_SKIP_DIR and DEP_DIRDEPS_FILTER
* sys.mk: extract some bits to sys.{debug,vars}.mk
for easier re-use by others.
2016-09-23 Simon Gerraty <sjg@sjg-mba13>
* lib.mk: Use ${PICO} for extension for PIC objects.
default to .pico (like NetBSD) safe on case insensitive filesystem.
2016-08-19 Simon J. Gerraty <sjg@bad.crufty.net>
* meta.sys.mk (META_COOKIE_TOUCH): use ${.OBJDIR}/${.TARGET:T} as default
Interesting changes:
o meta.c: move handling of .MAKE.META.IGNORE_* to meta_ignore()
so we can call it before adding entries to missingFiles.
Thus we do not track files we have been told to ignore.
o meta_oodate: apply .MAKE.META.IGNORE_FILTER (if defined) to
pathnames, and skip if the expansion is empty.
Useful for dirdeps.mk when checking DIRDEPS_CACHE.
o meta.c: remove all missingFiles entries that match a deleted
dir.
o main.c: set .ERROR_CMD if possible.
Interesting items from ChangeLog:
o cached_realpath(): avoid hitting filesystem more than necessary.
o meta.c: refactor need_meta decision, add knobs for
missing meta file and filemon data wrt out-of-datedness.
o meta.c: missing filemon data is only relevant if we read a
meta file.
Also do not return oodate for a missing metafile if gn->path
points to .CURDIR
Interesting changes (from ChangeLog):
o meta.c: ignore paths that match .MAKE.META.IGNORE_PATTERNS
this is useful for gcov builds.
o propagate errors from filemon(4).
o meta.c: apply realpath() before matching against metaIgnorePaths
o allow makefile to set .MAKE.JOBS
