feat: add initial types/logic to observe SQLite#32
Merged
Conversation
- We need a clean and reliable way to know when a SQLite
database has been updated (written to). SQLite provides
hooks which describe changes that have been committed
- Which table
- Which rowid
- Old and new values when applicable
- Phase 1 includes:
- The hooks part of the library which is the code that
communicates with the SQLite C ABI. We register for:
- Preupdate hook
- Commit hook (fires for implicit and explicit tx commits
- Rollback hook
- The `TableChange` and `ColumnValue` types
and helpers
- The broker API which takes subscriptions and manages
the buffer of change events
- Details about what's to come in the next two phases,
in the README
- Use of this feature requires that we bundle a version of
SQLite which supports these hooks, which we planned
to do anyway.

There was a problem hiding this comment.
@pmorris-dev Looks good, just a couple minor questions.
- It's the PK that the user really needs and that might not be the rowid - If the table schema includes WITHOUT ROWID, the first/only column making up the PK is returned. That's hokey. So now we return None for rowid in that case - Needed to add some introspection logic to find which column(s) make up the PK and whether the table was created using WITHOUT ROWID
