Relevant/interesting changes:
o parse.c: don't print null filename in stack traces
o for.c: skip syntactically wrong .for loops
o var.c: allow for :gmtime=${mtime}
add :mtime[=timestamp] where timestamp is used if stat(2)
fails, if :mtime=error stat(2) failure causes error.
o make.1: fix documentation of .PREFIX to match reality and POSIX
o unit-tests: improved var-scope-local
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
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/interesting changes:
o parse.c: fix out-of-bounds read when parsing an invalid line
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
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.
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.
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.
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

* Makefile (_MAKE_VERSION): 20161126
Merge with NetBSD make, pick up
o make.c: Make_OODate: report src node name if path not set

* Makefile (_MAKE_VERSION): 20160926
Merge with NetBSD make, pick up
o support for .DELETE_ON_ERROR: (remove targets that fail)

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 (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
Relevant items from ChangeLog:
o [Makefile.in:] protect syntax that only bmake parses correctly.
o compat.c: ignore empty commands - same as jobs mode.
o make.1: document meta chars that cause use of shell
