If it does, it is broken and should be fixed by using mktemp.

Interestingly, some stuff within src/lib/librumpuser uses
$RANDOM and assumes that it does what it says, deleting
old content in new supposedly random directory.

(lib/librumpuser/build-aux/install-sh, newest version still
does it, though.)

That wouldn't work too well for us - I wonder if that has
anything to do with the failures.

As far as I know nobody's sure what's causing those failures. There's
no errors during the build. Last I remember hearing it's thought to be
something wrong with tmpfs :(

Random build failures (rump)

2016-10-16 Thread coypu 
Hi,

There are sometimes build failures that seem to be from race conditions,
I've seen rump do it, maybe others too.

e.g. 
http://releng.netbsd.org/builds/netbsd-6/201610160430Z/ews4800mips.build.failed
http://releng.netbsd.org/builds/netbsd-6-1/201610122020Z/evbmips-mips64el.build.failed

It seems:

{src/sys/rump} % grep '\-l' */Makefile*
dev/Makefile.rumpdevcomp:RUMPDEVLDADD+=-lrumpdev_${var}
fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpfs_${var}
fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpvfs_${var}fs
fs/Makefile.rumpfscomp:RUMPFSLDADD+=-lrumpvfs_${var}
kern/Makefile.rumpkerncomp:RUMPKERNLDADD+=-lrumpkern_${var}
net/Makefile.rumpnetcomp:RUMPNETLDADD+=-lrumpnet_${var}

% ls librump
... rumpdevrumpkern   rumpnetrumpvfs

{src/sys/rump} % cat Makefile

SUBDIR= include
SUBDIR+=librump
SUBDIR+=dev fs kern net
SUBDIR+=share


Would adding
SUBDIR+=.WAIT dev fs kern net

be the right thing to resolve this dependency?

thanks.
