but if the file in question is one that needs to be compiled (.c or .cc),
it still hands the bogus name to the compiler.
If Dir_MTime() cannot find such a file (gn->iParents is not empty),
see if the basename can be found via .PATH, and if so set gn->path to
the found file. This prevents the stale path being given to the
compiler.
In meta_oodate(), if a referenced file no longer exists, consider the
target out-of-date.
Also, if meta_oodate() decides a target is out-of-date, and it
it uses .OODATE in its commands, we need .OODATE recomputed.
Undo our call to Make_DoAllVar() so that the call from Make_OODate()
will do the right thing.
In this mode, a .meta file is created for each target, capturing
the expanded commands used, any command output, and if filemon(9)
is available, a record of system calls which are of interest.
Not enabled unless USE_META=yes is set when building make.
Also, if FILEMON_H exists, meta.c will be compiled to use filemon(9).
If we encounter an error and run the .ERROR target, we may
reap a pid which jobs is waiting for. Ensure that we
cleanup so that make isn't left waiting for an already
deceased child.
As the comment says in JobPrintJob set JOB_IGNERR with - commands. Fix
whitespace so that the output is consistent, although there are two separate
execution logic implementations (command.c, job.c)
defined even in cases where the suffix search logic is skipped, such
as .PHONY targets, and fixes PR 43534.
Note: because .PHONY targets do not get suffix searching, .PREFIX will
not have any suffixes removed. This seems vaguely logical, although
it's not the only reasonable interpretation.
We may also want to reconsider whether suffix rules are skipped for
phony targets, too. That behavior is somewhat counterintuitive.
but not to track it - as is done for .export
This allows the variable to be updated without affecting what was put
into the environment.
Older versions of make will simply treat this as .export
realpath(3). Consider: touch Makefile; mkdir make; make. This will set $MAKE
to $PWD/make so further attempts to use ${MAKE} will try to execute the
directory. This needs $ORIGIN to be fixed properly, or alternatively one
can duplicate the logic for execvp(3) and search the path for the make
executable. Not worth it. It was working just fine before!
SunPro compiler defines __SVR4
We need to check both to ensure that on SunOS signal is hooked into
sigaction - otherwise we do not pass the unit-tests due to missing
a SIGCHLD
Reviewed by:
Reduced the "expected to exist" dirs in path to just
/ /bin and /tmp
and change the "not expected to exist" dir to something
even less likely.
Add a comment to suggest why.
Reviewed by:
modmisc: since we apply an exists() test to $paths, be conservative
in what we expect.
Run the unit tests with -r -m / so that we do not fail if there
is no sys.mk present.
