This commit fixes an issue where events in threads would occasionally
disappear.
Previously, the computation of parent events and reply events depended
on EventCache and had to be manually computed upon event selection
change. This may lead to inconsistencies if the computation is not
re-done after a new event that leads to a change in the model, or if certain
events are not yet on the cache. Instead, these are now computed
properties inside ThreadModel, and relies exclusively on the events
already in the ThreadModel.
Several other smaller improvements were made around the affected class,
including:
- Removing unused code for simplicity
- Configuring the class external interface with more intent, avoiding
misusage
- Adding more documentation on the usage of things, as well as
implementation notes on why certain design decisions were taken.
- Moving things to explicit actors, to integrate more structured concurrency
- Improving code efficiency to lower computational overhead on the main
actor
- Splitting concerns between objects with more intent and thoughful
design.
