Summary: This diff replaces the participant text fields with ones based on TokenizingTextField, a new core component that handles autocompletion, drag and drop of tokens, etc. Fix large queries overloading SQLite size limits New general purpose tokenized text field with token selection, copy paste, etc Move pre-send logic to the view since DraftStore requests from db, which may not have settled Tests - still a WIP Support for contextual menus instead of X Test Plan: Run new tests. Needs many more, but have higher priority things to fix Reviewers: evan Reviewed By: evan Differential Revision: https://review.inboxapp.com/D1142

# As the user interacts with the draft, changes are accumulated in the

# DraftChangeSet associated with the store proxy. The DraftChangeSet does two things:
|
|
#
|
|
# 1. It debounces changes and calls Actions.saveDraft() at a reasonable interval.
|
|
#
|
|
# 2. It exposes `applyToModel`, which allows you to optimistically apply changes
|
|
# to a draft object. When the proxy vends the draft, it passes it through this
|
|
# function to apply uncommitted changes. This means the Draft provided by the
|
|
# DraftStoreProxy will always relfect recent changes, even though they're
|
|
# written to the database intermittently.

# DraftStoreProxy is a small class that makes it easy to implement components
|
|
# that display Draft objects or allow for interactive editing of Drafts.
|
|
#
|
|
# 1. It synchronously provides an instance of a draft via `draft()`, and
|
|
# triggers whenever that draft instance has changed.
|
|
#
|
|
# 2. It provides an interface for modifying the draft that transparently
|
|
# batches changes, and ensures that the draft provided via `draft()`
|
|
# always has pending changes applied.
