De-optimise the getting of a job token so we don't re-order the job
list when there are no tokens.
This might have helped etc/Makefile, but isn't enough.
of trying to de-jobify the make.
You can now put .NOTPARALLEL in a submake of a recursive make (where it is
using a job-token pipe from the outer make and have it only run a single job.
You can also specify .NOTPARRALEL in the root makefile of a large recursive
make and have the submakes run multiple commands.
Add some diagnostics printfs (enabled with -dp) to the parser.
the first one for each make. This significantly speeds up the detection
of errors in other branches of the make (ie those running in a different
make process). The cost of reading and writing a byte from the pipe
should be insignificant.
Defer replacing job tokens until we've decided there is an error.
If we detect an error in another branch of the make, then call Fatal(),
setting 'aborting' and failing to return a token leads to infinite loops.
Now parallel makes actually stop with the failing command on the screen.
job_pipe and collect another one for the next job.
If we are aborting, remove all the 'normal' job tokens and add an 'error' one.
If we get an 'error' token, remove any other tokens, re-insert the error
token and exit (with error 'cos that is easier).
Add the current pid to some of the DEBUG(JOB) traces.
Combined effect is that parallel makes actually stop some fairly shortly
after an error, rather than running on long enough to fill the scrollback.
output in parallel makes.
After all with -s you wouldn't know the command for a non-parallel make.
Makes (sic) the output of parallel NetBSD build fathomable.
loop expansions, when the expanded variable ends in backslash and
the backslash is the last character on the line. While this fix is
ugly (detect the condition and append a space), it is the least
intrusive for now.
to document the behaviour that is currently in use (the "./obj" and
"/usr/obj/`pwd`" behaviour).
Hopefully the existing .OBJDIR behaviour is clearer now.
./obj.${MACHINE}
./obj
/usr/obj/${PWD}
The rules for the default .OBJDIR setting are now simplified to
(and documented as) trying the chdir to the following
(if the appropriate variable is defined):
${MAKEOBJDIRPREFIX}${.CURDIR}
${MAKEOBJDIR}
${.CURDIR}
.OBJDIR can be overridden in the makefile.
<bsd.obj.mk> uses this to provide the "culled" .OBJDIR semantics
for NetBSD's /usr/src builds.
MAKEOBJDIRPREFIX & MAKEOBJDIR still can only be provided
in the environment or on make(1)'s command line.
Per discussion on tech-toolchain.
This should reduce a lot of lossage people have experienced over
the years with various .OBJDIR setups.
mode, use the ignErr template for the command as shell doesn't like an empty
construct of the form { } || <something>. Fixes build breakage on cats
distrib where a command ends up expanding to nothing.
* Explicitly goto default_case for unknown chars encountered after
various : modifiers, rather than multiple FALLTHRUs.
* Appease gcc -Wuninitialized for sv_name and v_ctxt.
