Subject: Core dumps on freebsd8
While running the Yars 0.83_03 test suite, a couple of core dumps appeared on my system: $ ls -1 /tmp/yars.test.1023.*/* /tmp/yars.test.1023.0Fz1ND/perl.core /tmp/yars.test.1023.1NYpNU/perl.core /tmp/yars.test.1023.4shWdT/perl.core /tmp/yars.test.1023.4uPECA/perl.core /tmp/yars.test.1023.66aL5Q/perl.core /tmp/yars.test.1023.6d1NYp/perl.core /tmp/yars.test.1023.6dExlf/perl.core /tmp/yars.test.1023.8hP06N/state.txt /tmp/yars.test.1023.AZmw_1/state.txt /tmp/yars.test.1023.Cckktm/perl.core /tmp/yars.test.1023.ESCxAE/perl.core /tmp/yars.test.1023.EeVKnw/perl.core /tmp/yars.test.1023.FCi8_j/perl.core /tmp/yars.test.1023.IIVRyT/perl.core /tmp/yars.test.1023.JoDRPX/perl.core /tmp/yars.test.1023.JrgJFu/state.txt /tmp/yars.test.1023.MaV1Sn/perl.core /tmp/yars.test.1023.NWUqbf/perl.core /tmp/yars.test.1023.RBwXga/state.txt /tmp/yars.test.1023.TSd5aC/perl.core /tmp/yars.test.1023.UKuS2G/perl.core /tmp/yars.test.1023.VdTjhG/state.txt /tmp/yars.test.1023.WO77nR/state.txt /tmp/yars.test.1023._IJ4B5/state.txt /tmp/yars.test.1023.aYihF_/perl.core /tmp/yars.test.1023.c0szC1/perl.core /tmp/yars.test.1023.cU8z64/perl.core /tmp/yars.test.1023.d1NYpN/perl.core /tmp/yars.test.1023.dExlfq/state.txt /tmp/yars.test.1023.dTjhGc/perl.core /tmp/yars.test.1023.ekIHEa/state.txt /tmp/yars.test.1023.k7Twqe/perl.core /tmp/yars.test.1023.qjZ4sN/perl.core /tmp/yars.test.1023.rgJFu0/perl.core /tmp/yars.test.1023.rkS5TG/state.txt /tmp/yars.test.1023.s3DZiS/state.txt /tmp/yars.test.1023.sE2IGn/perl.core /tmp/yars.test.1023.uPECAd/perl.core /tmp/yars.test.1023.umnuCu/perl.core /tmp/yars.test.1023.vG6Ro8/perl.core /tmp/yars.test.1023.xZdnx6/state.txt /tmp/yars.test.1023.zcU8z6/state.txt /tmp/yars.test.1023.zp5z78/state.txt BTW: the test suite shouldn't use hardcoded /tmp here. On this system the TMPDIR environment variable is set to another directory. Best to use File::Temp::tempdir, which obeys all the best practices regarding temporary directories. Regards, Slaven

I removed the hard coded /tmp in 0.83_04 just now. Running the test suite on FreeBSD 9 was able to see a core dump, despite the test suite completing successfully, so I think one of the sub-processes is probably running out of memory. I think it is too aggressive about forking off too many threads. The test suite succeed?

With 0.83_05 the test passes on my freebsd9 system, but not on the older freebsd8 system. See: http://matrix.cpantesters.org/?dist=Yars;os=freebsd;reports=1#sl=5,1 Regards, Slaven

Just installed FreeBSD 8 in a VM (i386) wasn't able to reproduce this. Are there any other differences that may be relevant? Thanks, Graham

Are you still seeing any core dumps with version 0.84_02? I have substantially reworked the test suite.

No more core dumps, it seems. Looks good now. Regards, Slaven -- Slaven Rezic - slaven <at> rezic <dot> de Berlin Perl Mongers - http://berlin.pm.org
