Bug #56942 for IO-Compress: Testsuite fails when being run in parallel

Mon Apr 26 12:29:05 2010 rafl [...] debian.org - Ticket created

Subject:	Testsuite fails when being run in parallel
Date:	Mon, 26 Apr 2010 18:28:43 +0200
To:	bug-IO-Compress [...] rt.cpan.org
From:	Florian Ragwitz <rafl [...] debian.org>

The attached log shows how the IO-Compress testsuite fails miserably when being run in parallel, i.e. with prove -j2. Running the tests in order and one by one makes everything pass again. It'd be nice if the order dependencies between the tests could be eliminated so the tests can be run in a reasonable time on modern machines with more than one cpu. -- BOFH excuse #185: system consumed all the paper for paging

Hmmm, I'll see if I can sort that out.

Florian - was looking at this bug report you filed last year. Can you give me some details on how you ran the tests in parallel. I tried "make -j test" an that worked fine for me. cheers, and sorry for the delay in following up on this. Paul

after building, 'prove -b -j3 t/*.t' should do the trick. Also, if you have a recent enough test harness, setting the HARNESS_OPTIONS environment variable to 'j3' will also make 'make test' run its tests in parallel.

Hi Florian - setting HARNESS_OPTIONS did the trick. I'm seeing a pile of failures. I think they are all caused by using hard-wired filenames for temporary files. Should be easy to sort out. Paul

I've just uploaded a new version (2.034) of the module to CPAN that addresses the issue. Paul
