As a few of you will know, there's been some issues recently with Singular
failing to build in parallel due to incorrect dependencies in the Makefiles.
To test the latest Singular:
http://trac.sagemath.org/sage_trac/ticket/9946
A script called "gcc" was created, which waited for a random time before it
called the real gcc. This was in an attempt to find race conditions. The code I
wrote used /dev/urandom as a source of random numbers, and nanosleep() to sleep
for a random time. I've built Singular 500 times, and had no failures.
Today I decided to try to build the whole of Sage whilst inserting random delays
to gcc, g++ and gfortran. This was on a machine where I've built Sage 100's of
times (quite literally) with no problems at all. (It's a Sun Ultra 27 running
OpenSolaris 06/2009).
Anyway, when random delays were inserted in front of gcc, boehm_gc-7.1.p6 failed
to build. It looks to me like there's a race condition here. See below.
I note this package is called version 7.1, but the latest stable release is 6.8
as far as I can see from
http://www.hpl.hp.com/personal/Hans_Boehm/gc/
I find it quite annoying that we are using an unstable release, probably taken
from a CVS snapshot, but the package names gives no evidence of this.
Is there a good reason to use an unstable release?
I can hardly report this upstream, given it was a CVS snapshot taken at some
unknown date.
Note, the Sage package uses "make" and not "$MAKE" so it's not clear exactly
what happens in parallel here, but clearly something has gone wrong - see below.
When I removed the random delays, so the package built fine. So I'm pretty sure
I've uncovered a bug here.
