Description:
When you install perl-xml-sax it adds itself to its own config file, listing parsers, located at: /usr/share/perl5/vendor_perl/XML/SAX/ParserDetails.ini It doesn't remove itself from the list when the package is removed. This is a low priority, because when you uninstall perl-xml-sax there is nothing to read the ParserDetails.ini file any longer :). The bigger problem is other perl-xml-sax- modules copying the .install file from this package. Additional info: * perl-xml-sax version 0.96-2 * http://perl-xml.sourceforge.net/faq/#parserdetails.ini Background Info Rant: The link above gives a good description of the ParserDetails.ini problem. It says to update the ParserDetails.ini in a post-install script (as we do with post-xml-sax.install). Yet it says not to do this unconditionally, because you don't want to overwrite a better parser with the default one that comes with XML::SAX. This seems illogical, because perl-xml-sax is a pre-requisite to parsers like perl-xml-sax-expat. This means perl-xml-sax will be installed first and need not worry about another parser being installed before it. Nevertheless I don't want to rock the boat and keep the file readability (-r) checks in my bugfix snippet below. Steps to reproduce: pacman -S perl-xml-sax pacman -R perl-xml-sax cat /usr/share/perl5/vendor_perl/XML/SAX/ParserDetails.ini Fix: Add an entry for removal inside the perl-xml-sax.install file, like so: pre_remove() { if [ -r /usr/share/perl5/vendor_perl/XML/SAX/ParserDetails.ini ] ; then perl -MXML::SAX \ -e "XML::SAX->remove_parser(q(XML::SAX::PurePerl))->save_parsers()" &>/dev/null fi } PS: I don't think the post_upgrade() function in the perl-xml-sax.install file is necessary. PPS: I will try to remember to report this for perl-xml-sax-expat etc... |
