Intersting/relevant changes since bmake-20240520 ChangeLog since bmake-20240520 2024-06-25 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240625 Merge with NetBSD make, pick up o job.c: ensure shellPath is always duped, avoid upsetting free() 2024-06-16 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240616 Merge with NetBSD make, pick up o clean up collection of context information for error messages o in warnings, move the word "warning" to the front o var.c: throw an error on attempt to override an internal read-only variable 2024-06-10 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240610 Merge with NetBSD make, pick up o for.c: remove redundant shortcut for building the .for loop body 2024-06-02 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240602 Merge with NetBSD make, pick up o rename some VarEvalMode constants to better match debug names. o var.c: avoid out-of-bounds read when parsing indirect modifiers. 2024-06-01 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240601 Merge with NetBSD make, pick up o add .export-all rather than allow .export with no argument which can happen accidentally. o if lua is available, run check-expect.lua after unit-tests o main.c: use snprintf rather than strncpy fix memory leak when purging realpath cache. 2024-05-28 Simon J Gerraty <sjg@beast.crufty.net> * VERSION (_MAKE_VERSION): 20240528 Merge with NetBSD make, pick up o fix a number of memory leaks o replace magic numbers with POSIX FILENO constants o hash.c: remove dead code from HashTable_DeleteEntry o main.c: when complaining about unusable .OBJDIR call PrintOnError if MAKE_DEBUG_OBJDIR_CHECK_WRITABLE is true. o parse.c: use fewer technical terms in debug message for dependency mk/ChangeLog since bmake-20240520 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 computed build dirs, since some filters cannot be easily expressed via DEP_DIRDEPS_FILTER. 2024-05-31 Simon J Gerraty <sjg@beast.crufty.net> * dirdeps.mk: move reset of DIRDEPS_EXPORT_VARS until after we a finished with it if building a cache.
