ProtectedFile
A special file-object class that automatically does a 'chmod +w' when
needed.
XXX: for now, the way it is done allows 'normal file-objects' to be
created during the ProtectedFile object lifetime.
One way to circumvent this would be to chmod / unchmod on each
write operation.
One other way would be to :
- catch the IOError in the __init__
- if IOError, then create a StringIO object
- each write operation writes in this StringIO object
- on close()/del(), write/append the StringIO content to the file and
do the chmod only once
