Bug #1868 for XML-Parser: use strict problem in XML::Parser

Wed Dec 11 16:09:26 2002 Guest - Ticket created

Subject:

use strict problem in XML::Parser

I'm seeing an error in my SOAP logs regarding XML/Parser/Expat.pm at line 456. I'm using Perl 5.6.1 on a stock RedHat 7.3 box, with XML::Parser 2.31 and SOAP::Lite 0.55. Here's the error: Can't use string ("<?xml version="1.0" encoding="UT") as a symbol ref while "strict refs" in use at /usr/lib/perl5/site_perl/5.6.1/i386-linux/XML/Parser/Expat.pm line 456. Not doing anything special with the SOAP client -- just defining URI and PROXY and calling my service. Have you ever seen this error? Adding no strict refs seems to fix it. Line: 456 eval { no strict 'refs'; $ioref = *{$arg}{IO}; }; Your thoughts? PaulM

My thoughts are that strict complained for a reason and this bug should not have been fixed by disabling strict. Debian seems to have patched their copy using your suggestion, but that introduced a severe memory leak that renders the module unusable in persistent Perl environments.

Since submitting this bug, have learned a lot. Fully agree with you about not disabling strict; I did it because I saw it done elsewhere in the code. As you indicate, it produces all kinds of evilness. The problem, as it turned out, was a die SIG handler in the code that was using XML::Parser. Dies in XML::Parser were getting handled by this handler. That seems unfortunate. The solution was to localize the handler (this was possible because the handler was installed in a subroutine -- don't know what people would do if their SIG handler is global). Anyway, thanks for the response. Anybody reading this: don't disable strict!
