08:15 chm CHM/PDL-2.013_01.tar.gz released to CPAN: http://sourceforge.net/p/pd​l/mailman/message/34500541/
08:16 chm sivoais, mohawk: tests and feedback welcome.  I think we need a better t/bigmem.t strategy
08:17 chm We're getting lots of FAIL reports due to OOM.  Apparently, some CPAN Testers are not setting AUTOMATED_TESTING
11:27 lungching joined #pdl
14:29 preaction hmm... someone in #cpantesters-discuss might be able to help with that. i'd be interested to know why myself
14:58 jberger chm: are you sure that they are CPAN Testers and not just people installing with a reporter plugin?
15:27 sivoais that's a good point
15:30 sivoais is there a module on CPAN to portable determine how much memory a system has?
15:35 sivoais I can't find one, surprisingly. Though, I didn't check for long.

22:38 chm joined #pdl
22:38 chm jberger: the OOM fails are from slaven who has been running testers for quite some time
22:39 chm I have an email to him asking if he could re-enable AUTOMATED_TESTING in the env
22:40 chm sivoais: I did some research into this but the key is to use a separate process so the perl test harness doesn't die on OOM
22:40 chm The only foolproof way to get an idea of the amount of memory is to try.
22:41 chm Basically, in a separate command we malloc/free by increasing sizes until failure.
22:41 chm Then back off from that by some amount.
22:42 chm The could be a simple c program that outputs how big works by iteration.
22:42 chm From perl we just read the output and use the last output value for the estimate.
22:42 chm With that info, we can just make bigmem not use more than 1/2 the available memory.
22:43 chm That should avoid many FAILs while still allowing tests to proceed if possible.
22:43 chm We could even skip tests if the available memory was too small to make a difference.
