I recently upgraded from 5.9 to 5.12.
My init.sage file loads/attaches a .sage file that I often use. In 5.9, that file was still attached when I started up a worksheet in the notebook. In 5.12, it is attached in the terminal, but when I then start open a worksheet in the notebook, it seems to be no longer attached since none of my functions are known any more and give a NameError when tried.
What can I do to fix this?
Hello! The problem is in file
$SAGE_ROOT/spkg/bin/sage-env
>>import os
>>os.environ['SAGE_STARTUP_FILE']
/home/andrei/.sage//init.sageFirst, what OS are you using? Second, what is the bug here? (Having multiple slashes in a row doesn't actually affect the path: `/home/andrei/.sage/init.sage` and `/home/andrei/.sage//init.sage` point to the same file.) Third, making your change doesn't seem to have any effect: the file will still be loaded from the command-line, and not from the notebook.

What is the exact syntax you used? This has recently changed (though I thought it was before 5.9) and conceivably affected things.
It looks to me as though this broke between Sage 5.10 (where it works) and 5.11 (where it doesn't). I think the problem was introduced in http://trac.sagemath.org/ticket/14523.
This bug has now been reported at http://trac.sagemath.org/ticket/15308.
I have a problem that may be related. I use load_attach_path followed by attach. I get the error "NameError: name 'var' is not defined" from within the attached file. I am using Ubuntu 12.04 x64 and using the Sage notebook. This worked in 5.10 and stopped working in 5.11.
I've also reported this upstream at https://github.com/sagemath/sagenb/issues/251
