retitle 760841 pspp: random testsuite failures thanks Affects GNU/Linux too! It's odd the issue has only been seen yet on kfreebsd rather than linux buildds; I reproduced it on linux-amd64, and with similar ~2% probability:
> ~/pspp-0.8.3$ for i in $(seq 1 1000) ; do printf 'e\0n\0t\0r\0\351\0e\0\n\0' > | tests/libpspp/u8-istream-test read - Auto | xxd ; done | sort | uniq -c | > sort -bn > 21 0000000: 6500 6e00 7400 7200 c3a9 0065 000a 00 e.n.t.r....e... > 979 0000000: 656e 7472 c3a9 650a entr..e. For sanity, I've checked that printf is working correctly: > ~/pspp-0.8.3$ for i in $(seq 1 1000) ; do printf 'e\0n\0t\0r\0\351\0e\0\n\0' > | xxd ; done | sort | uniq -c | sort -bn > 1000 0000000: 6500 6e00 7400 7200 e900 6500 0a00 e.n.t.r...e... So it may be related to how the tests/libpspp/u8-istream-test program does its reads from stdin? I'm also curious why the read is truncated only sometimes - possibly a glibc issue there? A potential workaround in the pspp testsuite is to use a temporary file for the test input, this always seems to work correctly. (Please see attached). I'm hoping the test runs in its own, clean working directory so that a parallel-running test can't overwrite the input file, I haven't checked this. Regards, -- Steven Chamberlain ste...@pyro.eu.org
