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
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)
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.
