2024-06-22 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240616
* dirdeps.mk: apply DEP_DIRDEPS_BUILD_DIR_FILTER after we have

2024-05-20 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION):
Merge with NetBSD make, pick up
o dir.c: in FindFile restore last search of .CURDIR even for
includes, as a number of existing makefiles are broken otherwise.

2024-05-07 Simon J Gerraty <sjg@beast.crufty.net>
* VERSION (_MAKE_VERSION): 20240508
Merge with NetBSD make, pick up
o make: ensure variables set on command line get added to
.MAKEOVERRIDES (even if they start with '.') so they are passed to
sub-makes.
mk/ChangeLog since bmake-20240430
2024-05-04 Simon J Gerraty <sjg@beast.crufty.net>
* install-mk (MK_VERSION): 20240504

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

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

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:
o optimize string matching for ':M' and ':N'
o warn about malformed patterns in ':M', ':N' and '.if make(...)'

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 @+-

https://bugs.freebsd.org/265119
fix memory leak in wildcard targets and sources
fix off-by-one error in buffer for .WAIT nodes
o allow to randomize build order of targets
.MAKE.MODE += randomize-targets can help uncover dependency bugs
Most relevant change:
o parse.c: try to include 'posix.mk' the first time
.POSIX: is encountered, to allow for beter POSIX compliance.
Others
o cond.c: make debug logging for comparisons less technical
o lst.c: fix mem leak in Lst_Remove
o job.c: fix echoing of command with '-' in silent target in jobs mode
o var.c: make debug logs more readable
prefer 'long long' over 'long' on 32-bit C99 platforms
fix crash on .undef of an environment variable
* unit-tests/Makefile: disable opt-debug-x-trace on Linux if there
is any chance we have dash as .SHELL
* meta.c: use a variable to hold command line to be filtered
to avoid any side effects from content of command line.
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.
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.
Lots more unit tests and code cleanup
Relevant changes from ChangeLog
o job.c: Print -de error information when running multiple jobs
o var.c: only report error for unmatched regex subexpression
when linting (-dL) since we cannot tell when an unmatched
subexpression is an expected result.
reduce memory allocations in the modifiers ':D' and ':U'
reduce memory allocation and strlen calls in modifier ':from=to'
in the ':Q' modifier, only allocate memory if necessary
improve performance for LazyBuf
reduce debug logging and memory allocation for ${:U...}
reduce verbosity of the -dv debug logging for standard cases
fix double varname expansion in the variable modifier '::='
o var.c: avoid evaluating many modifiers in parse only mode
in strict mode (-dL) many variable references are parsed twice,
the first time just to report parse errors early, so we want to
avoid side effects and wasted effort to the extent possible.
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
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
Change-Id: I4d3bcf08b4c864d98b343f602efe5a75dbfa7a94
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.

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.
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.
from ChangeLog:
(most of this by rillig@)
o lots of style and white-space cleanup
o lots more unit tests for variable modifiers
o simplified description of some functions
o str.c: refactor Str_Match
o var.c: debugging output for :@
constify VarModify parameter
fix :hash modifier on 16-bit platforms
remove unnecessary forward declarations
refactor ApplyModifier_SysV to have less indentation
simplify code for :E and :R
clean up code for :H and :T
refactor ApplyModifiers
* var.c: we need stdint.h on some platforms to get uint32_t
* unit-test/Makefile: we need to supress the specific error
for RE substitution error in modmisc, since it varies accross
different OS.
from ChangeLog:
o cond.c: do not eval unnecessary terms of conditionals.
o meta.c: report error if lseek in filemon_read fails
o str.c: performance improvement for Str_Match for multiple '*'
o dieQuietly: supress the failure output from make
when failing node is a sub-make or a sibling failed.
This cuts down greatly on unhelpful noise at the end of
build log. Disabled by -dj or .MAKE.DIE_QUIETLY=no
o unit test for :Or
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
o parse.c: ParseVErrorInternal use .PARSEDIR
and apply if relative, and then use .PARSEFILE
for consistent result.
o var.c: avoid SEGFAULT in .unexport-env
when MAKELEVEL is not set
Of relevance:
o job.c: skip polling job token pipe
o parse.c: be more cautious about detecting depenency line
rather than sysV style include.
also in mk:
* dirdeps.mk: include local.dirdeps-build.mk when .MAKE.LEVEL > 0
ie. we are building something.
* FILES: add dirdeps-options.mk to deal with optional DIRDEPS.
* ldorder.mk: describe how to use LDORDER_EXTERN_BARRIER
if needed.

* 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.

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
