[Pythonmac-SIG] macostools.copytree() problems...

[Jack Jansen]

After looking at this for a long time I think I have a possible solution.
If NOVELL_SERVER:Home:User:Whatever exists, and let's say for sake of argument 
that there's nothing in there at the moment, then it's OK to copy something 
into NOVELL_SERVER:Home:User:Whatever:bla but it is NOT ok to copy something 
into NOVELL_SERVER:Home:User:Whatever:bla:bletch. Or, in other words: copytree 
will create the destination but it will not create the whole path leading up 
to the destination.

You can use mkdirs to do this, something like this just before the copytree 
call:
    parent_d = os.path.split(d)[0]
    macostools.mkdirs(parent_d)

But note that this is all from just thinking about the problem a bit, so it 
could be wildly off.

PS: here's a tip: if you run this thing under the IDE you get a chance to 
inspect the variables after the crash. If you can't run under the IDE for some 
reason: <option>drag the script to PythonInterpreter, set the "interactive 
mode after script" flag, run, watch it crash and at the >>> prompt do "import 
pdb" and "pdb.pm()" and you're also able to inspect things. In your case 
srcfss and dstfss should be interesting, both printed as-is and with 
.as_pathname().
>  f=open('backuplist', 'r+')
