d6806f69d maintain a way to access the correlations in relation to the correlation keys
065a86cde BPMN Parser was returning all retrieval expressions, rather than the ones specific to a correlation property, as was intended. Adding a correlation cache - so we have a reference of all the messages and properties (though still lacking a description of keys) Adding yet another migration, maybe should squash em.

72a7e535a BPMN.io -- Just show the message names not the ids - to assure we are only exposing the names. SpiffWorkflow - - start_messages function should return message names, not ids. - don't catch external thrown messages within the same workflow process - add an expected value to the Correlation Property Model so we can use this well defined class as an external communication tool (rather than building an arbitrary dictionary) - Added a "get_awaiting_correlations" to an event, so we can get a list of the correlation properties related to the workflows currently defined correlation values. - workflows.waiting_events() function now returns the above awaiting correlations as the value on returned message events Backend - Dropping MessageModel and MessageCorrelationProperties - at least for now. We don't need them to send / receive messages though we may eventually want to track the messages and correlations defined across the system - these things (which are ever changing) should not be directly connected to the Messages which may be in flux - and the cross relationships between the tables could cause unexpected and unceissary errors. Commented out the caching logic so we can turn this back on later. - Slight improvement to API Errors - MessageInstances are no longer in a many-to-many relationship with Correlations - Each message instance has a unique set of message correlations specific to the instance. - Message Instances have users, and can be linked through a "counterpart_id" so you can see what send is connected to what recieve. - Message Correlations are connected to recieving message instances. It is not to a process instance, and not to a message model. They now include the expected value and retrieval expression required to validate an incoming message. - A process instance is not connected to message correlations. - Message Instances are not always tied to a process instance (for example, a Send Message from an API) - API calls to create a message use the same logic as all other message catching code. - Make use of the new waiting_events() method to check for any new recieve messages in the workflow (much easier than churning through all of the tasks) - One giant mother of a migration.
cb2ff8a93 * SpiffWorkflow event_definitions wanted to return a message event's correlation properties mested within correlation keys. But messages are directly related to properties, not to keys - and it forced a number of conversions that made for tricky code. So Messages now contain a dictionary of correlation properties only. * SpiffWorkflow did not serialize correlations - so they were lost between save and retrieve.
d4852a1a5 * Re-work message tests so I could wrap my simple head around what was happening - just needed an example that made sense to me. * Clear out complex get_message_instance_receive how that many-to-many works. * Create decent error messages when correlations fail * Move correlation checks into the MessageInstance class * The APIError could bomb out ugly if it hit a workflow exception with not Task Spec.
