in reply to New Module Announcement: Object::InsideOut

I tried to build this on AS810 (5.8.4) and I am getting test failures in 03-threads.t.

NMAKE : fatal error U1077: 'C:\Perl\bin\perl.exe' : return code '0x2' Stop.

Tracing the testscript through, the failure appears to be when the test for is_sharing() is called at InsideOut.pm(388):

# Share the hash, if applicable if (is_sharing($pkg)) { threads::shared::share($hash) }

and

sub is_sharing : PRIVATE { my $class = $_[0]; # If not 'use threads::shared;', return false if (! $threads::shared::threads_shared) { return; } return ($IS_SHARING{$class}->[0]); }

The if suceeds, so the function returns undef with the result that the hash is not shared.

Without claiming to have read or traced every line, I cannot see anywhere in InsideOut.pm where threads::shared is ever used or required. What am I missing?

    All the failures you received were due to your not having Exception::Class installed ("Can't locate Exception/Class.pm in @INC"), and had nothing to do with the presense or absense of threads::shared.

    As to your question concerning threads::shared, it is documented in the POD, namely, the application must use threads::shared;. t/03-threads.t is testing threads without object sharing and thus does not use threads::shared. However, t/04-shared.t does. Hope that helps.

      I do apologise, it appears I c&p'd the wrong log. This is the one I should have posted

NMAKE : fatal error U1077: 'C:\Perl\bin\perl.exe' : return code '0xff' Stop.

      As you can see, I have installed Exception::Class, but I am still getting failures from 03threads.t

        This looks to be a bug in Perl and may be related to this bug fix reported in perl585delta.pod:
        Creating a new thread when weak references exist was buggy, and would often cause warnings at interpreter destruction time.
        I'll investigate this further. Thanks.

        Update:
        After further investigation, I'm fairly sure this is a Perl bug. I could not reproduce the error you received under Cygwin or Solaris, but I did reproduce the warnings mentioned in the quote above. Further, 03-threads.t and 04-shared.t are nearly the same, and 04-shared.t successed for you. I can only recommend upgrading to Perl 5.8.7 if you can.

        I'll make note of these sorts of issues in the bug section of the POD.
