* Reorganize the Handler architecture to a pipeline architecture with plugins.Barry Warsaw2008-02-171-1/+1
| | | | | | | | | | | | | | | | Now plugins can define additional handlers and the handlers can be organized into named pipelines. Modules are no longer the unit of a handler, now we use classes so we can assert interface conformance. The GLOBAL_PIPELINE is gone, replaced by the 'built-in' pipeline. The OWNER_PIPELINE is not yet replaced. I still need a few more tests of the basic pipeline architecture, although the individual handlers have pretty good coverage. Added the IHandler and IPipeline interfaces. Still broken, but not yet removed: Mailman/pipeline/moderate.py.
* SpamDetect is gone, so the chains/rules implementation experiment is deemed aBarry Warsaw2008-02-011-8/+7
| | | | | | | | | | | | | | | | | | | | success and will now be merged into the trunk. Move the Truth rule into the built-in rules package in a separate module, and add a test. Modify IChainLink so that the rule and chain attributes are not names but indeed the actual ILink or IChain object directly. Update the chains.process() function accordingly. Remove the IChain.get_rule() method. Don't derive BuiltInChain from Chain and don't make it an IMutableChain. It's now just an IChain, and is implemented concretely. Refactor the HeaderMatchChain and friends so that it can be used with both the global HEADER_MATCHES variable and the list-specific header_matches variable, which has exactly the same semantics. Oh yeah, get rid of the list's header_filter_rules attribute and replace it with header_matches so that the semantics match, it's easy to explain, and it's all nice and clean.

| | | | | | | | | | | Create a Mailman.chains package and move a bunch of the Mailman.apps.chains classes to separate modules under this package. Also, separate out iteration from chain management. In other words, IChain and IChainIterator are separate, and the latter is retrieved from the former by the .get_links() method. This latter takes the mailing list, message, and metadata dictionary so that links can be targetted specifically to the task at hand.

| | | | | | | | | | | | | | | variable to the new chain processing system. Create a header-matching chain which handles global site header matching rules defined by HEADER_MATCHES. Rip this logic out of the SpamDetect handler; really this entire handler needs to go away but the rest of it isn't ported yet. IChains now have a get_rule() method which allows them to return private (i.e. not globally registered) rules. This is used by the header matching chain. Mailman.app.chains.process() has had its parameter list reordered to be more like all other function signatures that take a mailing list, message, and message metadata.
* More changes to rules and chains.Barry Warsaw2008-01-231-58/+105
| | | | | | | | | | | | | Now a link has a rule, action, chain, and function, not all of which needs to be specified. The action is a LinkAction enum adn specifies what to do should the rule match. The use of the chain or function depends on what the action is. Several interface changes now make it easier to jump to other chains, push (i.e. detour) to chains, etc. Rules can also now specify that they should not be recorded in X-* headers. Added a TruthRule which always matches.
* More updates to rules and chains, especially by adding additional tests.Barry Warsaw2008-01-211-24/+67
| | | | | | | | | | | | | | | - Remove the Emergency.py handler. This is now covered by the emergency.py rule. - Remove the hold.txt doctest. This is now covered by the chains.txt and emergency.txt doctests. - Added a chains.txt doctest. - Extend the pending db to handle list values, although only lists that contain nothing but strings. - Rename the 'adminapproved' message metadata key (for the emergency rule) to 'moderator_approved'. Also, backport a change to the Decorate handler where message metadata on the 'decoration-data' key ca be used in the header and footer.
