Subject:

'cpan install LWP' fails due to circular dependency

With a fresh perl-5.21.8 I'm trying to install libwww-perl, but can't (without user intervention) due to it depending on LWP-Protocol-https, which in turn depends on LWP::UserAgent, which is part of libwww-perl. In particular, the tests for LWP-Protocol-https require LWP::UserAgent, which obviously isn't installed yet. Complete output of 'cpan install LWP' is attached.

In fact, the installation of LWP still fails even after a forced installation of LWP-Protocol-https because its own test suite fails to run, complaining "Can't open perl script "t": Permission denied". Output of 'cpan install LWP' after manually installing LWP-Protocol-https attached.

For me, the test suite fails: robot/ua-get.t ...... 2/8 HTTP Server terminated robot/ua.t .......... 2/7 HTTP Server terminated and more of those failures. I'm using Strawberry Perl 5.20.1 64-bit. I *think* this might be a Perl 5.20 failure rather than a perl failure, I remember having built 6.06 before on Windows and can't remember having seen the isuse before. Right now, also 6.06 fails with these errors. Do you experience the same? ActiveState perl seems to work OK. -- Michiel

Just an idea: is recommends_policy enabled in your CPAN.pm's configuration? LWP-Protocol-https is listed as "recommends", see https://metacpan.org/source/MSCHILLI/libwww-perl-6.08/META.yml#L22 If this is the case, then probably LWP-Protocol-https should not list LWP as a prereq, and the test suite should be skipped if LWP is not yet installed, similar to the DateTime <-> DateTime::TimeZone combo.

Yes, I did indeed have 'recommends_policy' => q[1], in my .cpan/CPAN/MyConfig.pm. I wasn't aware of that setting; it was just its default value. If I change that to 'recommends_policy' => q[0], then the output (attached) is much as before, but stops after the LWP test failures, without then attempting (and failing) to install LWP-Protocol-https. So yes, I think your suggestion would fix the main subject of this ticket. The failure of the LWP test suite is a separate issue, which I will log a new ticket for.
