Dear maintainer, in the context of Reproducible Builds, we noticed that eztrace can't reliably be built because it (can?) generate very huge files that fills the entire file system (and we have a 200GB file system). For example: mattia@profitbricks-build5-amd64 /srv/workspace/pbuilder % sudo lsof 2>/dev/null | grep deleted | grep eztrace sh 64627 1111 1w REG 0,34 205408100352 2360061294 /srv/workspace/pbuilder/3308/build/eztrace-1.1/build-mpich/test/automake/testlog0.txt (deleted) litl_prin 64628 1111 1w REG 0,34 205408100352 2360061294 /srv/workspace/pbuilder/3308/build/eztrace-1.1/build-mpich/test/automake/testlog0.txt (deleted) litl_prin 64628 1111 3r REG 0,34 570 2360034123 /srv/workspace/pbuilder/3308/tmp/pbuilder1_eztrace_log_rank_1 (deleted) mattia@profitbricks-build5-amd64 /srv/workspace/pbuilder % That means a ~200GB file got written (actually is still getting written), then removed but the process keeping it open (for writing) is still open. This is the 3rd time I have to kill extrace after having messed up with our builders (and now I'm going to blacklist it from testing...). That's not the only file, the other day I noticed that after killing those 2 processes keeping that file opened 2 other started growing very fast (like 1GB every 30 seconds), and in very little time they reached 50+ GB. I noticed this only happens in amd64, not in armhf, I believe this is some kind of issue with highly parallelized builds, since we build with parallel=16. Furthermore the tests are not considered in the build process, so they are actually completely useless, so I even wonder what's the whole point on running them... override_dh_auto_test: -dh_auto_test -Bbuild-mpich -- -k Thanks for maintaining eztrace. -- regards, Mattia Rizzolo GPG Key: 66AE 2B4A FCCF 3F52 DA18 4D18 4B04 3FCD B944 4540 .''`. more about me: http://mapreri.org : :' : Launchpad user: https://launchpad.net/~mapreri `. `'` Debian QA page: https://qa.debian.org/developer.php?login=mattia `-
