Errors "list must have an even number of elements"

[vinc17@…]

I often get errors "list must have an even number of elements". For instance:

$ port list
Error: search for portname .+ failed: list must have an even number of elements
$ port list all
Error: /opt/local/bin/port: search for portname * failed: list must have an even number of elements
$ port echo maintainer:vincent-opdarw@vinc17.org
Error: /opt/local/bin/port: search for portname vincent-opdarw@vinc17.org failed: list must have an even number of elements

Can you please try running any of those commands with the -d switch? That should give a stack trace.

Sounds like you have a damaged PortIndex file. If you have an svn checkout of the dports tree, do an svn update and make sure your PortIndex file isn't modified. Otherwise do a sudo port sync.

[vinc17@…]

That was the problem (I sometimes run portindex manually, and after a svn update, it gets corrupted... it seems that I forgot to revert it or rerun it). Shouldn't the port command detect corrupted PortIndex files and provide a meaningful error message?

Ok, r26040 adds a warning when it thinks your PortIndex file is corrupt.
