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 (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.
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
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
