Duplicate options are allowed in sections of trac.ini — at Initial Version
|Reported by:||Ryan J Ollos||Owned by:|
The sections of trac.ini allow duplicate options, with later values overwriting those that come first. Two patterns are possible, which could lead to confusing behavior when the user doesn't realize there the value is being redefined later in the file:
- Duplicate sections with the same option.
[trac] default_handler = WikiModule ... [trac] default_handler = TicketModule
- Duplicate options within a section.
[trac] default_handler = WikiModule ... default_handler = TicketModule
While Python 3.x has a much improved configparser module with a
strict mode that raises an error when an option is redefined, I'm not sure there is much we can do in Python 2.x using
SO:5396653 suggests using a
dict_type that allows multiple values with the same key, however
dict_type is only supported in Python 2.6.
