Hey folks,
I've been reading the code for portupgrade and have come across =
something I don't understand at all.
In the lib/portsdb.rb, the glob method starts on line 757.
On line 773, as part of the glob method, we have the following:
<---snip--->
# shortcut
if portinfo =3D port(pattern)
if block_given?
yield(portinfo)
return nil
else
return [portinfo]
end
end
end
<---/snip--->
Won't the condition "if portinfo =3D port(pattern)" always evaluate to =
true, as it's an assignation not a test? Is it meant to read if portinfo =
=3D=3D port(pattern)?
If so, there are then a fair few tests which use =3D instead of =3D=3D
If not, what's the purpose?
Thanks!
