Intersting/relevant changes since bmake-20240309 ChangeLog since bmake-20240309 2024-04-30 Simon J Gerraty * VERSION (_MAKE_VERSION): 20240430 Merge with NetBSD make, pick up o main.c: ensure '.include ' respects MAKESYSPATH. Dir_FindFile will search .CURDIR first unless ".DOTLAST" is seen. 2024-04-28 Simon J Gerraty * 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 * 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 * VERSION (_MAKE_VERSION): 20240424 Merge with NetBSD make, pick up o clean up comments, code and tests 2024-04-23 Simon J Gerraty * 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 * 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 * 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 * 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 * 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 * meta.autodep.mk: do not override start_utc 2024-04-18 Simon J Gerraty * 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 * 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 * install-mk (MK_VERSION): 20240314 * add sys/Cygwin.mk from Christian Franke

Interesting/relevant changes since bmake-20230909 * VERSION (_MAKE_VERSION): 20240106 Merge with NetBSD make, pick up o fix duplicate progname when reporting an unknown target o unit tests for Cmd_Exec using temp file * VERSION (_MAKE_VERSION): 20240105 Merge with NetBSD make, pick up o main.c: Cmd_Exec write cmd to a file if too big avoid blowing commandline/env limits * VERSION (_MAKE_VERSION): 20240101 o util.c: flesh out more of strftime * configure.in: add --with-bmake-strftime it is not a full implementation but enough to pass all the unit-tests. * parse.c: LoadFile do not append \n to empty buffer. * VERSION (_MAKE_VERSION): 20231230 Merge with NetBSD make, pick up o simplify memory allocation for string buffers o fix declared types of list nodes o suff.c: clean up freeing of suffixes o var.c: simplify debug message for the ':@var@...@' modifier clean up variable handling * VERSION (_MAKE_VERSION): 20231226 Merge with NetBSD make, pick up o compat.c: ensure make's output is correctly ordered with that of the target when not going to a tty o main.c: check for shellPath whether to call Shell_Init() * VERSION (_MAKE_VERSION): 20231224 Merge with NetBSD make, pick up o compat.c: check for shellPath whether to call Shell_Init() tweak the unit test to detect the bug thus fixed. o make.1: do not claim .SHELL is only used by jobs mode. * VERSION (_MAKE_VERSION): 20231220 Merge with NetBSD make, pick up o str.c: speed up pattern matching in the ':M' modifier o var.c: fix confusing debug logging when deleting a variable use consistent debug messages style when ignoring variables * VERSION (_MAKE_VERSION): 20231210 Merge with NetBSD make, pick up o var.c: avoid segfault on empty :C match expression explain in debug log why variable assignment is ignored. * VERSION (_MAKE_VERSION): 20231208 Merge with NetBSD make, pick up o var.c: ensure fromCmd is set correctly for variables set on command line. * VERSION (_MAKE_VERSION): 20231124 Merge with NetBSD make, pick up o main.c: cleanup processing of -j 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

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

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.

2021-02-11T01:51:11Z

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

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.
