Subject: libxml-sax-perl: Problem installing package (conflicts with CPAN version of
 SAX.pm)
Date: Fri, 23 Jan 2004 14:47:34 +0000

Package: libxml-sax-perl
Version: 0.12-3
Severity: normal

Ardo,

I've been having some trouble installing the debian package libxml-sax-perl; the problem seems to be that XML/SAX.pm was already 
installed via CPAN (as a dependency for another module); the configuration stage of libxml-sax-perl runs the script 
/usr/bin/update-perl-sax-parsers, which calls XML::SAX->save_parsers_debian(..) (line 90). Now, if SAX.pm has already been installed 
by CPAN it will not contain save_parsers_debian, so the script will die (there is no check carried out for this function actually 
being present, nor does the script attempt to recover if the function is missing).

The CPAN version of SAX.pm *does* contain a function called save_parsers - my "solution" was simply to comment out line 90 in 
/usr/bin/save-perl-sax-parsers and replace it with 'XML::SAX->save_parsers( $add, $directory[0] );'

This will probably cause me pain at some point, but I couldn't find any other way (and I wasn't keen to simply delete the existing 
SAX.pm, in case it broke some other CPAN module).

I'm not sure quite what the way forward is here, especially since there isn't 100% overlap between CPAN and apt-get; is there any 
mileage in trying to modify the debian version of CPAN.pm, perhaps to install the relevant debian packages where the are available? I 
haven't checked to see if it already does this, or something like it, but given what happened with SAX.pm and libxml-sax-perl, I;d 
guess not.

Thanks,

Etienne Pollard

ardo,

> See /usr/share/doc/libxml-sax-perl/README.Debian.gz.

thanks for the pointer - I neglected to mention in the bug report that I 
had already read that file, and had noted the "please don't do this" 
comment with respect to CPAN installation of XML::SAX.

in the case where the module XML::SAX has already been installed via 
CPAN, being told after the fact that one shouldn't have installed the 
CPAN version isn't much help!

what is the recommended course of action here - simply deleting 
/usr/local/share/perl/<xx>/XML/SAX.pm, or something else? it might be 
useful if README.Debian reflected whatever you recommend (I could write 
a detailed entry if you let me know roughly what should happen).

>>The CPAN version of SAX.pm *does* contain a function called save_parsers - my "solution" was simply to comment out line 90 in 
>>/usr/bin/save-perl-sax-parsers and replace it with 'XML::SAX->save_parsers( $add, $directory[0] );'

for instance, noting that this change allows the package to be 
configured might be a good thing to have in README.Debian?

thanks,

etienne

[Message part 1 (text/plain, inline)]

Hi, All,

This old bug is the result of a number of people (including myself) who
have installed SAX.pm from CPAN and later attempted to install the
Debian libxml-sax-perl.  This behavior is discouraged in
/usr/share/doc/libxml-sax-perl/README.Debian, but as Etienne points out,
this message necessarily comes too late to people in our circumstances.

I did the following, and it might be worth suggesting in README.Debian.

First remove the CPAN version without removing any dependencies.  I
believe the script at:

http://www.cpan.org/misc/cpan-faq.html#How_delete_Perl_modules

accomplishes this.  It must be modified for the correct debian path to
perl (/usr/bin/perl).  Call the script remove.pl or something and do:

# ./remove.pl XML::SAX

Once the CPAN version is gone, the libxml-sax-perl package will install.

Hope this helps.  Of course it doesn't deal with the underlying problems of
having a mixed Debian/CPAN perl system.

Yours,

Streph

   * Move the /etc/perl/XML/SAX/ParserDetails.d directory under
     /var/lib/libxml-sax-perl, since it's not really configuration data.
   * Use ucf to manage local changes to /etc/perl/XML/SAX/ParserDetails.ini.
   * Remove the pre-sarge preinst cleanup of /etc/XML and /etc/perl/SAX
     introduced in 0.12-3.
     + Now survives systems with a leftover symlink /etc/perl/XML -> .
       (Closes: #240356)
   * Point to the compressed file in XML::SAX::save_parsers(). (Closes: #332440)
   * Recommend libxml-sax-expat-perl and explain this in the package
     description. (Closes: #420867)
   * Upgrade to debhelper compatibility level 5.

   * Various improvements in debian/rules.
     + remove generated files in the 'clean' target.
   * Update debian/watch.
   * Move the examples under debian/, they are Debian-specific.

       a non-free input file.
   * Move update-perl-sax-parsers under debian/ in the source package, it's
     Debian-specific.
   * Remove an unused Debian modification: XML::SAX->load_parsers() doesn't
     accept the '$file' argument anymore.
   * README.Debian: add a pointer to the CPAN FAQ entry on uninstalling local
     modules. Thanks to Streph Treadway <sbt@ginkwunk.net>. (Closes: #229178)
   * Make update-perl-sax-parsers bail out with an informative error message
     if there's a locally installed XML::SAX module breaking the installation.
     (See #229178)
   * Repackage the upstream tarball to remove the non-free
     testfiles/xmltest.xml file. (Closes: #452872)

     his DM powers :)
