Sudden death of PDF::API2
I have an Intel MacPro running Mac OS X 10.5.6 (Perl 5.8.8) and a copy of PDF::API2. This has worked flawlessly for a long time. Suddenly it has failed. There have been no changes at all to the machine apart from a recent 'Security Update', which I think had to do mostly with a loophole in Safari. This minimal script: my $pdf_in = PDF::API2-open($file_in) or die $!\n; my $pdf_out = PDF::API2-new or die $!\n; $page = $pdf_out-page; $page-mediabox(595, 842); $gfx = $page-gfx; #$xo = $pdf_out-importPageIntoForm($pdf_in, 1); #$gfx-formimage($xo, 0, 0, 1); fails with the error message: Undefined subroutine Compress::Zlib::compress called at /Library/Perl/ 5.8.8/PDF/API2/Content.pm line 103. However the folder 'Compress' is there, (alongside the folder 'PDFwhich contains the module), the file 'Zlib' in that folder, and Zlib has a subroutine named 'compress'. So what can possibly have gone wrong here? If the last two lines above are uncommented, the error message becomes: Can't call method infilt on an undefined value at /Library/Perl/ 5.8.8/PDF/API2/Util.pm line 667. presumably as a result of failure to access Zlib subroutines? I have run 'repair permissions' which has not altered the situation and run out of ideas of what to do next. I would be most grateful if anyone could help. Alan Fry
Re: Sudden death of PDF::API2
I did also had problems with perl scripts after installing the security patch. Strategy for fixing has been worked out and reported here: http://bulknews.typepad.com/blog/2009/02/mac-os-x-security-update-2009001-br eaks-perl-cpan.html As well as in Apple forum http://discussions.apple.com/thread.jspa?threadID=1905157tstart=0 This recipe worked for me so far.

--As of February 15, 2009 11:10:33 AM +, Alan Fry is alleged to have said: I have an Intel MacPro running Mac OS X 10.5.6 (Perl 5.8.8) and a copy of PDF::API2. This has worked flawlessly for a long time. Suddenly it has failed. There have been no changes at all to the machine apart from a recent 'Security Update', which I think had to do mostly with a loophole in Safari. --As for the rest, it is mine. From the notes on the recent Security Update: perl CVE-ID: CVE-2008-1927 Available for: Mac OS X v10.4.11, Mac OS X Server v10.4.11, Mac OS X v10.5.6, Mac OS X Server v10.5.6 Impact: Using regular expressions containing UTF-8 characters may lead to an unexpected application termination or arbitrary code execution Description: A memory corruption issue exists in the handling of certain UTF-8 characters in regular expressions. Parsing maliciously crafted regular expressions may lead to an unexpected application termination or arbitrary code execution. This update addresses the issue by performing additional validation of regular expressions. So, they definitely updated Perl. Likely any/all XS modules will need to be recompiled. I'd _hope_ that Apple updated the ones they shipped, but you'll still have to update any you've installed yourself. (I haven't gotten around to installing the update myself yet...) Daniel T.
