`port -b` or `buildfromsource never` do not prevent local compilation if Portfile clears archive_sites

[burner1024 (Ilya Ivanov)]

Both "-b" option and "buildfromsource never" don't work for me.

OSX 10.10.5

Fresh MacPorts installation (from .pkg)

# port version
Version: 2.3.4

# grep buildfromsource /opt/local/etc/macports/macports.conf
buildfromsource     	never

# port installed
No ports are installed.

# port -b -v install gmp

That's odd, the url in the output above does not exist.

http://jog.id.distfiles.macports.org/macports/mpdistfiles/gmp

But this does:

The rsync module used to be called mpdistfiles. It was changed to just distfiles some years ago. The administrator of the jog.id mirror must have changed their server to match. Fixed mirror_sites.tcl in r146625 and updated wiki:Mirrors. This is tangential to the issue reported in this ticket, however.

I'm not able to reproduce the problem reported here. buildfromsource never and the -b flag both work for me on MacPorts 2.3.4. I can't explain this. I'm on 10.11, not 10.10, and I do already have some ports installed, but that shouldn't matter.

Note that gmp clears archive_sites in order to deliberately prevent installing from an archive. You should still get an error in binary-only mode though.

[burner1024 (Ilya Ivanov)]

Strange: another port (ansible) does fail installation with the very same config and command.

(Edit: and I'm not sure if that's correct, too, since ansible doesn't need any compilation)

That doesn't sounds strange; that sounds like it's working as you intend. Sounds like the only reason why gmp is being handled differently is because it deliberately disabled the use of prepackaged archives, and MacPorts base may not have accounted for that situation.

Compilation no, but assembly yes. There are still instructions in the portfile for what to install where, that must still be followed, if a prepackaged archive is not available. And one is not available for ansible, because its license does not allow it:

"ansible" is not distributable because its license "gpl" conflicts with license "OpenSSL" of dependency "openssl"

All right. I'm not sure what would be the correct behaviour for MacPorts in this situation, so I guess I'll just leave it in your hands. If I can assist somehow, please let me know.
