pythonalgorithms.directory key is still used in GUI dialog

[Martyn Gigg]

From James Lord,

I had a directory with a few Mantid algorithms of my own ready to load on start up.

Starting Mantid 2.5 I get an orange warning error:

"The Python algorithms key 'pythonalgorithms.directories' in 'C:\MantidInstall\bin\Mantid.user.properties' has been deprecated. Please add 'C:/MantidInstall/UserAlgorithms/AutoLoaded' to the 'user.python.plugins.directories' key instead. Future release will not check the old key."

I looked in Mantid.user.properties and temporarily commented out the line

#pythonalgorithms.directories=C:/MantidInstall/UserAlgorithms/AutoLoaded

and restarted Mantid. Now no error, but no User algorithms auto loaded either.

So I went to View-Preferences-Mantid-Directories where the "Python Algorithms" box is now empty. I put my directory back in, then "OK" and restart Mantid.

The orange warning is back! And in the properties file, Mantid has written a new pythonalgorithms.directories line for me. (my commented out one is still there too, and my algorithms are back in the list)

Finally I reopened Mantid.user.properties in Notepad and manually edited the key name of the offending line to 'user.python.plugins.directories' as it asks. Now I have algorithms and no warnings. So maybe it's the Preferences dialog box that is obsolete?

This was resolved under #7103

I tested this as part of the release 2.5.3 code review.
