Wrong CPANPLUS::Backend::parse_module() result with GRICHTER/HTML-Embperl-1.2.1.tar.gz

Dear Jos Boumans, Hi. This is imacat from Taiwan. I found that the parse_module() method of CPANPLUS-0.84 returns a wrong module with GRICHTER/HTML-Embperl-1.2.1.tar.gz. imacat@rinse ~ % /opt/perl/testers/5.8.8/bin/perl -mCPANPLUS::Backend -e'@_ = CPANPLUS::Backend->new->parse_module("module" => "GRICHTER/HTML-Embperl-1.2.1.tar.gz"); print $_[0]->package;'; echo [MSG] Checking if source files are up to date [MSG] Retrieving /home/imacat/.cpanplus/sourcefiles.2.18.stored Embperl-1.2.1.tar.gz imacat@rinse ~ % As the above shows, it returns Embperl-1.2.1.tar.gz, but not HTML-Embperl-1.2.1.tar.gz. As a result, CPANPLUS fails download when trying to test or install GRICHTER/HTML-Embperl-1.2.1.tar.gz, creating dummy Makefile.PL in the current working directory of the user, and doing non-sense make and install there. Hope that this helps. Please tell me if you need any more information, or if I could be of any help. Thank you.

This is actually correct. If you look at the file that's been uploaded to CPAN, it's indeed Embperl-*.tar.gz: CPAN Terminal> l HTML::Embperl [MSG] Checking if source files are up to date [MSG] Retrieving /Users/kane/.cpanplus/sourcefiles.2.16.stored [MSG] Adding packages from custom source 'file:///tmp' Details for 'HTML::Embperl' Author Gerald Richter (richter@ecos.de) Description Build dynamic Websites (e.g. embed Perl) Development Stage Released Interface Style plain Functions, no references used Language Used C and perl, a C compiler will be needed Package Embperl-2.3.0.tar.gz Public License Standard-Perl: user may choose between GPL and Artistic Support Level Mailing-list Version on CPAN 2.003000 Contains: Apache::Embperl Embperl The Embperl package happens to contain HTML::Embperl as well, which may not be quite standard, but it is the way it is.

When trying this on my machine, when asked to fetch HTML::Embperl, it downloads the proper Embperl-*.tar.gz file, so i can not reproduce this. Show quoted text

If you have a way to reproduce this error, please let me know.

Thank you for your reply. HTML::Embperl is http://search.cpan.org/dist/HTML-Embperl/ where Embperl is http://search.cpan.org/dist/Embperl/ Maybe they are a same distribution which has changed its distribution name. However, when I specify I want to download G/GR/GRICHTER/HTML-Embperl-1.3.6.tar.gz with CPANPLUS, it tries to download G/GR/GRICHTER/Embperl-1.3.6.tar.gz instead, which does not exists at all. (Of course, the final "Successfully fetched" message is another problem here. It did not succeed.) imacat@rinse ~ % /opt/perl/testers/5.8.8/bin/cpanp -d G/GR/GRICHTER/HTML-Embperl-1.3.6.tar.gz [MSG] Checking if source files are up to date [MSG] Retrieving /home/imacat/.cpanplus/sourcefiles.2.18.stored [MSG] Trying to get 'ftp://cpan.cdpa.nsysu.edu.tw/Unix/Lang/CPAN/authors/id/G/GR/GRICHTER/Embperl-1.3.6.tar.gz' Fetch failed!

This is where the information differs. we base everything on the 02packages file from the CPAN mirror, and that says: HTML::Embperl 2.003000 G/GR/GRICHTER/ Embperl-2.3.0.tar.gz And that's why you get this result, plain and simple. If that's in error, we should report this eitehr to the pause indexer, or to the author. Show quoted text

Hmm... So CPANPLUS discards the user-specified full distribution path, decomposes it into scratches, and recomposes it with internal distribution path rules? That does not make sense. I thought user-specified distribution path should be respected first, and recomposition should only happen when the user specifies a module name (or something looks like a module name). Though I understand it now.

WIth this directive, the point is to find the module *from cpan* that matches your criteria. To do that, we need to look at the meta data provided. If you want to go completely outside that, provide a full path to the archive you want installed, ie: http://foo.com/GRICHTER/HTML-Embperl-1.2.1.tar.gz And no logic will be applied.
