Do not allow installing ports with non-numerical revision

[ballapete (Peter "Pete" Dyballa)]

ort outdated
The following installed ports are outdated:
cmake                          3.7.1_0 < 3.7.2_0         
can't use non-numeric string as operand of "-"
    while executing
"expr {$installed_revision - $latest_revision}"
    (procedure "action_outdated" line 84)
    invoked from within

    (procedure "process_cmd" line 103)
    invoked from within
"process_cmd $remaining_args"
    invoked from within
"if { [llength $remaining_args] > 0 } {

    # If there are remaining arguments, process those as a command
    set exit_status [process_cmd $remaining..."
    (file "/opt/local/bin/port" line 5286)

and similarly:

It sounds like maybe you have a port installed whose revision is not a number. revision is supposed to always be a number, but nothing prevents portfile authors from committing revisions that are not numbers.

Does port installed work? If so, can you show us its output?

Replying to ryandesign:

Yes, it does! It lists over 300 active packages.

[ryandesign (Ryan Carsten Schmidt)]

Please show us the output. Perhaps put it into a file (e.g. port installed > ~/Desktop/installed_ports.txt) and attach that file to this ticket.

The ports installed on my Mac

So the culprit would be emacs @25.1_2a+imagemagick+x11 (active). It doesn't look like the emacs port in the official ports tree ever had that revision; is your emacs Portfile locally modified? Either way, you should be able to fix the problem by uninstalling emacs.

Yes, that modified package, to allow GNU Emacs to use local init files and calendar, was indeed the culprit. Port was too fast upgrading so that I chose that version number.

Everything is working fine now. The ticket can be closed. Thank you!

I consider this a bug in base. port should fail and abort when trying to install a port with a non-numerical revision. The best fix would be to stop that early on and reject such an invalid revision.

In that case, dupe of #26486.
