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.
it's (more) consistent in the tree; this, along with changing tools/compat's
autoconf detection from AC_CHECK_FUNCS to AC_CHECK_DECLS makes the vast
majority of htobe16 and friends' redefinition errors bite the dust.
Tested with -current and FreeBSD.
Similarly for dkswap().
Allows code to only call one of these.
Rename struct _disk to _vminfo to be nearer its contents.
Change 'systat vm' so that it always shows the 'current' cpu times, even
after ':run' or ':boot' commands. The code in vmstat.c doesn't support :run.
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.
This adds a -e option to progress which causes the progress bar to be
sent to stderr. This allows using progress mid-pipe, such as:
tar -cf . | progress -e bzip -1c | ssh host "cat > file"
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.
