I've reduced it to "perl -MPDL::Core -MCrypt::Random -e ''" and I still = get the error in Crypt::Random, so it isn't Net::SSH::Perl related. = That's not to say that I or someone else on the list won't help you = figure it out, of course; I'll keep looking into it. It looks like the issue involves Exporter (possibly the export cache), = perhaps PDL is doing evil things? -----Original Message----- From: ssh...@li... on behalf of Sean = Quinlan Sent: Wed 2/23/2005 2:35 PM To: ssh...@li... Cc: pe...@ja... Subject: [Ssh-sftp-perl-users] 'new' breaks if using PDL. I have a function in a module which executes a long process (blast) on a remote server via Net::SSH::Perl (NSP). This function is used by a number of different programs quite successfully (thanks!). However it recently started failing spectacularly in a program after I started using a module based on PDL (pdl.perl.org). The Perl version, OS and errors are below. I'm using NSP version 1.27 and PDL version 2.4.0. I've confirmed this as best I can by first stripping out use of my PDL based modules, then adding them back piece by piece. The error below doesn't occur until I have to add C<use PDL;> back in. I've also done a trial case by adding C<use PDL;> to a program that uses the blast function without error, and adding just the use statement causes the same errors as below. My first guess is this is from a namespace conflict of some kind? I'm hoping someone on these lists can help narrow down and resolve this issue with far more alacrity than I, although I am digging.

This is (I think) actually a more general issue related to the UNIVERSAL package that comes with Perl. It's discussed here: http://www.xray.mpe.mpg.de/mailing-lists/perl5-porters/2003-10/msg00163.html I had to modify UNIVERSAL.pm on my system to get rid of these errors. ---- Steve Sapovits |

I'll look at it more closely in the morning. I notice that Crypt::Random uses *import =3D \&Exporter::import; Which is mentioned in the docs the email your referred to quotes. Is that what is the source of the error? I'd never seen that before. Do you have a guess why that conflicts with PDL when PDL doesn't seem to have a 'makerandom'? Personally I'd rather patch the modules than mess with UNIVERSAL, but if you could provide you patch so I could test it (rather than poke around myself for a bit ;) I'd appreciate it.

W00T!!
Thanks Christian! That patch does seem to have fixed the problem. :) It
has moved past that point on to another bug! I'll look over the
UNIVERSAL fix Steve referred to JIK I need that later anyway. But unless
PDL starts to fail because of this patch (I'll let you know immediately
if it does), I seem to be back to debugging our own code.
Thanks everyone!

I don't remember the details -- it's been a while since I patched it. What I do remember is that trying to patch the modules reporting the error just kept moving it to new modules and that only making the UNIVERSAL.pm change fixed it. I believe once I fixed it in the Crypt modules, it moved to something entirely unrelated. In part of the thread I referenced, there is a simple fix to UNIVERSAL.pm that fixes it for everyone. If you have more issues I'll see if I can find any remains of what I did in email threads, etc. ---- Steve Sapovits |

Having now read the source for Crypt::Random, that's looking more likely to be the case. I'm trying to find anything in PDL that might indicate culpability. I didn't grep any instances of 'makerandom' in the PDL source, which is too bad. I was really hoping it might be some odd namespace clash that could be found relatively easily. I did find this: /usr/local/lib/perl5/site_perl/5.8.3/alpha-dec_osf-thread-multi/auto/Crypt/Random/.packlist:/usr/local/bin/makerandom But I don't see how that would be the source of conflict. > -----Original Message----- > From: ssh...@li... on behalf of Sean Quinlan > Sent: Wed 2/23/2005 2:35 PM > To: ssh...@li... > Cc: pe...@ja... > Subject: [Ssh-sftp-perl-users] 'new' breaks if using PDL. > I have a function in a module which executes a long process (blast) on a > remote server via Net::SSH::Perl (NSP).
