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

# Tests for parsing expressions with modifiers.
|
|
|
|
# As of 2020-10-02, the below condition does not result in a parse error.
|
|
# The condition contains two separate mistakes. The first mistake is that
|
|
# the :!cmd! modifier is missing the closing '!'. The second mistake is that
|
|
# there is a stray '}' at the end of the whole condition.
|
|
#
|
|
# As of 2020-10-02, the actual parse result of this condition is a single
|
|
# expression with 2 modifiers. The first modifier is
|
|
# ":!echo "\$VAR"} !". Afterwards, the parser optionally skips a ':' (at the
|
|
# bottom of ApplyModifiers) and continues with the next modifier, in this case
|
|
# "= "value"", which is interpreted as a SysV substitution modifier with an
|
|
# empty left-hand side, thereby appending the string " "value"" to each word
|
|
# of the expression.
|
|
#
|
|
# As of 2020-10-02, some modifiers ensure that they are followed by either a
|
|
# ':' or the closing brace or parenthesis of the expression. The modifiers
|
|
# that don't ensure this are (in order of appearance in ApplyModifier):
|
|
# :@var@replacement@
|
|
# :_
|
|
# :L
|
|
# :P
|
|
# :!cmd!
|
|
# :gmtime=...
|
|
# :localtime=...
|
|
# :M (because '}' and ')' are treated the same)
|
|
# :N (because '}' and ')' are treated the same)
|
|
# :S
|
|
# :C
|
|
# :range=...
|
|
# On the other hand, these modifiers ensure that they are followed by a
|
|
# delimiter:
|
|
# :D
|
|
# :U
|
|
# :[...]
|
|
# :gmtime (if not followed by '=')
|
|
# :hash (if not followed by '=')
|
|
# :localtime (if not followed by '=')
|
|
# :t
|
|
# :q
|
|
# :Q
|
|
# :T
|
|
# :H
|
|
# :E
|
|
# :R
|
|
# :range (if not followed by '=')
|
|
# :O
|
|
# :u
|
|
# :sh
|
|
# These modifiers don't care since they reach until the closing character
|
|
# of the expression, which is either ')' or '}':
|
|
# ::= (as well as the other assignment modifiers)
|
|
# :?
|
|
#
|
