Intersting/relevant changes since bmake-20251111 ChangeLog since bmake-20251111 2026-03-12 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260313 Merge with NetBSD make, pick up o make: ensure .MAKE.SAVE_DOLLARS is initialized so makefiles like sys.vars.mk can test its value to know how to deal with macros that need to save '$' during ':='. * Makefile: default MAKE_SAVE_DOLLARS_DEFAULT to "no" for traditional behavior. 2026-03-10 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260310 Merge with NetBSD make, pick up o unit-tests ensure TEST_MAKE is absolute path and tests that make symlink for ${MAKE} can run in parallel. 2026-03-03 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260303 Merge with NetBSD make, pick up o job.c: MaybeSubMake: Look for expansion of ${.MAKE} and if necessary its basename, and only match if at start of line or preceded by space. 2026-02-28 Simon J Gerraty <sjg@beast.crufty.net> * Makefile: mark ${PROG} and ${OBJS} as .META MaybeSubMake will otherwise mistake them for sub-makes * VERSION (_MAKE_VERSION): 20260301 Merge with NetBSD make, pick up o job.c: MaybeSubMake: skip control chars [@+-] at start of line when checking for ${MAKE} 2026-02-22 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260222 o mk file update 2026-02-16 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260216 Merge with NetBSD make, pick up o minor cleanups 2026-02-10 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260210 Merge with NetBSD make, pick up o document that multiple variables can be set on command line. o move MaybeSubMake to job.c so it can be called on expanded commands for more accuracy and less overhead. o main.c: set .MAKE.VERSION as read-only. * unit-tests/opt-{chdir,where-am-i}.mk: use MAKEOBJDIRPREFIX=/ to avoid tripping over an unreadable /usr/obj 2026-02-04 Simon J Gerraty <sjg@beast.crufty.net> * unit-tests/varname-make_stack_trace.mk: for FreeBSD and similar set .MAKE.ALWAYS_PASS_JOB_QUEUE=no to ensure we get the expected errors. * VERSION (_MAKE_VERSION): 20260202 Merge with NetBSD make, pick up o on error avoid duplicate stack trace to stderr 2026-01-11 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260111 Merge with NetBSD make, pick up o var.c: add explicit check for empty re as not all regex libs throw an error as expected, in this case. 2026-01-10 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20260110 Merge with NetBSD make, pick up o minor cleanups mk/ChangeLog since bmake-20251111 2026-03-12 Simon J Gerraty <sjg@beast.crufty.net> * install-mk (MK_VERSION): 20260313 * sys.vars.mk: use .MAKE.VERSION M_type can simply use '$x' 2026-02-22 Simon J Gerraty <sjg@beast.crufty.net> * install-mk (MK_VERSION): 20260222 * dirdeps.mk, sys.mk: add dependent option UPDATE_DIRDEPS_CACHE/DIRDEPS_CACHE. It can be useful to use -DWITHOUT_UPDATE_DIRDEPS_CACHE to temporarily treat dynamic DIRDEPS_CACHE as static. 2026-01-10 Simon J Gerraty <sjg@beast.crufty.net> * meta.autodep.mk (${_DEPENDFILE}): add .NOMETA 2026-01-08 Simon J Gerraty <sjg@beast.crufty.net> * rust.mk: better accommodation for RUST_LIBS. Set RUST_{LIBS,PROGS}_CARGO_BUILD_OUTPUT_LIST to simplify staging. 2025-12-08 Simon J Gerraty <sjg@beast.crufty.net> * install-mk (MK_VERSION): 20251207 * sys.vars.mk: replace MAKE_POSIX_SHELL usage with isPOSIX_SHELL Using ${isPOSIX_SHELL:U:Nfalse} provides a boolean for make and ${isPOSIX_SHELL:Ufalse} does the same for target scripts. Both will be false if isPOSIX_SHELL is not set or set to false. This has the advantage that if only POSIX shells are expected sys.mk (or something it includes) can simply do isPOSIX_SHELL?=:
