Package File and CHECKSUMS from Different Mirror Sources

Hi. This is imacat from Taiwan. I found that CPAN is NOT downloading CHECKSUMS alone with the package file (*.tar.gz) from the SAME source. This morning when I was updating the newly-updated DBI-1.53, it cannot match CHECKSUMS with DBI-1.53.tar.gz since they came from 2 different sources, and each has its own mirror schedule. The package file DBI-1.53.tar.gz came from a mirror that has it, but CHECKSUMS came from another that doesn't have it yet. Shouldn't they be downloaded from the same mirror source? The result is below. Please tell me if there is any problem. Thank you. root@odin~# cpan T/TI/TIMB/DBI-1.53.tar.gz CPAN: File::HomeDir loaded ok Going to read /root/.cpan/sources/authors/01mailrc.txt.gz CPAN: Compress::Zlib loaded ok Going to read /root/.cpan/sources/modules/02packages.details.txt.gz Database was generated on Wed, 01 Nov 2006 22:24:31 GMT CPAN: HTTP::Date loaded ok Going to read /root/.cpan/sources/modules/03modlist.data.gz CPAN: Storable loaded ok Going to write /root/.cpan/Metadata Running make for T/TI/TIMB/DBI-1.53.tar.gz CPAN: LWP::UserAgent loaded ok Fetching with LWP: ftp://cpan.cdpa.nsysu.edu.tw/Unix/Lang/CPAN/authors/id/T/TI/TIMB/DBI-1.53.tar.gz LWP failed with code[404] message[File 'DBI-1.53.tar.gz' not found] Fetching with Net::FTP: ftp://cpan.cdpa.nsysu.edu.tw/Unix/Lang/CPAN/authors/id/T/TI/TIMB/DBI-1.53.tar.gz Couldn't fetch DBI-1.53.tar.gz from cpan.cdpa.nsysu.edu.tw: Can't open DBI-1.53.tar.gz: No such file or directory Fetching with LWP: ftp://cpan.cs.pu.edu.tw/pub/CPAN/authors/id/T/TI/TIMB/DBI-1.53.tar.gz LWP failed with code[404] message[File 'DBI-1.53.tar.gz' not found] Fetching with Net::FTP: ftp://cpan.cs.pu.edu.tw/pub/CPAN/authors/id/T/TI/TIMB/DBI-1.53.tar.gz Couldn't fetch DBI-1.53.tar.gz from cpan.cs.pu.edu.tw: Can't open DBI-1.53.tar.gz: No such file or directory Fetching with LWP: ftp://ftp.stu.edu.tw/CPAN/authors/id/T/TI/TIMB/DBI-1.53.tar.gz CPAN: Digest::SHA loaded ok Fetching with LWP: ftp://cpan.cdpa.nsysu.edu.tw/Unix/Lang/CPAN/authors/id/T/TI/TIMB/CHECKSUMS Warning: No checksum for DBI-1.53.tar.gz in /root/.cpan/sources/authors/id/T/TI/TIMB/CHECKSUMS. The cause for this may be that the file is very new and the checksum has not yet been calculated, but it may also be that something is going awry right now. Proceed? [yes]

For young files there is often a short timespan within which there is no entry in the checksums file yet, even if they come from the same host. As you are always working with very young files, I'm surprised it doesn't happen more often to you. But in principle you are right, CPAN.pm should try to get checksums file from the same host because the likelihood is higher to get an uptodate one. I'll investigate if there is a chance. -- andreas

In fact you are right. It happens all the time for me, since I update my system very often. But this is the first time I decide to report it and work it out. I shouldn't ignore the warning forever. Show quoted text

Thank you for taking care of this issue.
