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.

avoid blowing commandline/env limits
* VERSION (_MAKE_VERSION): 20240101
o util.c: flesh out more of strftime

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
Update import.sh to generate below
ChangeLog since bmake-20230622
2023-09-09 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20230909
Merge with NetBSD make, pick up
o main.c: allow -j to compute a multiple of ncpu
If _SC_NPROCESSORS_ONLN is supported; and -j arg is a floating
point number or ends in 'C' compute .MAKE.JOBS as a multiple of
_SC_NPROCESSORS_ONLN
.MAKE.JOBS.C will be "yes" if -jC is supported
2023-08-20 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20230820
Merge with NetBSD make, pick up
o make.1: note that :localtime is better for %s
o parse.c: improve error messages for invalid input.
o var.c: fix for %s:L:gmtime - set TZ=UTC and use localtime to get
correct result, it is still better to use %s:L:localtime.
2023-08-18 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20230818
Merge with NetBSD make, pick up
o meta.c: meta_ignore - check raw path against metaIgnorePaths
to potentially skip call to realpath.
o var.c: be strict when parsing the argument of the ':mtime' modifier
o unit-tests/varmod-mtime.mk: document why '${%s:L:localtime}'
should be used to get an equivalent value to time(3).
2023-08-16 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20230816
Merge with NetBSD make, pick up
o cond.c: clean up multiple-inclusion guards
2023-07-25 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* boot-strap op_test: ensure we set TEST_MAKE as we want it.
mk/ChangeLog since bmake-20230622
2023-09-09 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* now_utc: %s only works with :localtime
2023-07-14 Simon J Gerraty <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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 <sjg@beast.crufty.net>
* 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.
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

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.
Changes of interest
o unit-tests: use private TMPDIR to avoid errors from other users
o avoid strdup in mkTempFile
o always use vfork
o job.c: do not create empty shell files in jobs mode
reduce unnecessary calls to waitpid
o cond.c: fix debug output for comparison operators in conditionals
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
from ChangeLog:
o filemon/filemon_dev.c: use O_CLOEXEC rather than extra syscall
o meta.c: target flagged .META is out-of-date if meta file missing
o cond.c: fix for compare_expression when doEval=0
o unit-tests/Makefile: rework
o filemon/filemon_dev.c: ensure filemon fd is closed on exec.
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
