[mp2] mod_perl2 + XML::LibXML = OK ?
Hi, Are there any problems using XML::LibXML and XML::LibXSLT with mod_perl 2 (perl 5.8)? (everything is the latest versions as grabbed from Randy's site ;) win32). My primary concern is thread-safety (is XML::LibXML thread-safe?), but anything I should be aware about would be nice to know. Thanks, -Kurt. __ kurt george gjerde [EMAIL PROTECTED] intermedia uib, university of bergen I don't work here.
Re: [MP2] bug report startup and XML::LibXML
Hi !
and as suggested :
LIBXML2.DLL VERSION 2.4.26
XML::LibXML version 1.52
I've tested with libxml2-2.4.23 and XML::LibXML 1.53 on linux
and it works
just fine.
I tested it with libxml2-2.4.23 and XML::LibXML 1.52
and it still segfaults.
this looks suspicious as address: 0xabababab, as you have
traced it. So it
could be a bug in the ActiveState's perl or is it a standard
one?
it is perl 58 cpan source I have rebuilt all myself debug
but the bug also happens with asperl 58
here is more precicion, I have followed the trace starting with
perl_croak :

Though the good thing is that it happens on croak (something went wrong). So
perhaps you can check why does it happen in first place. I'd at the above frame.

[ MP2] startup problem with XML::LibXML
PROBLEM :
APACHE SEGFAULT WITH XML::LibXML on
WIN32
I use all in one perl + apache + modperl2 RK
binaries
but I replace c:\perl\bin\perl58.dll with
perl58.dll obtained after separately(and succesfully) compiling perl with vc6
DEBUG so that I get symbols in
perl58.dll
so the call stack gives line number in source (see
below)
everything works normally as far as I tried
prepared scripts in RK distribution, but my test.pm makes an APACHE

USE from a registry CGI works
USE from a modperl handler (mason)
works
!!! use test(); from startup.pl output ok BUT

Sorry about that - the ARCHITECTURE in the .ppd file wasn't set properly, which has now been fixed. This particular package contains a post-install script which installs the needed libxml2.dll - if that doesn't work, grab the accompanying .tar.gz under the x86/ subdirectory which, when unpacked, has this dll. -- best regards, randy

XML::LibXML
Hi, sorry for this question that is not directly related to mod_perl, rather to perl itself. I use XML::LibXML, that I found on http://www.xml.com, and it matches my needs. Because it might (surely!) be good code structure examples, I had a look at the module. There comes my question : I do not understand how it works. I know (guess?) my answer in somwhere linked with Dynaloader. But I do not find the link between XML::LibXML and libxml2. Do not man have to specify it somewhere? Where is the link between C libs and Perl? How come can calls to undefined methods like $self-_parse_file() (in method XML::LibXML-parse_file()) can be found? Where is the inheritance defined? Well, I have to say that I did not investigate much on Dynaloader. I thing I missed a step before reading perldoc Dynaloader. If somebody has an hint (or an URL?, manpage?) for me starting at understanding this process, I would be grateful ! Thanks, Fred
