sqlite: fixes from sytest (#872)
* bugfix: fix panic on new invite events from sytest

I'm unsure why the previous code didn't work, but it's
clearer, quicker and easier to read the `LastInsertID()` way.
Previously, the code would panic as the SELECT would fail
to find the last inserted row ID.

* sqlite: Fix UNIQUE violations and close more cursors

- Add missing `defer rows.Close()`
- Do not have the state block NID as a PRIMARY KEY else it breaks for blocks
  with >1 state event in them. Instead, rejig the queries so we can still
  have monotonically increasing integers without using AUTOINCREMENT (which
  mandates PRIMARY KEY).

* sqlite: Add missing variadic function

* Use LastInsertId because empirically it works over the SELECT form (though I don't know why that is)

* sqlite: Fix invite table by using the global stream pos rather than one specific to invites

If we don't use the global, clients don't get notified about any invites
because the position is too low.

* linting: shadowing

* sqlite: do not use last rowid, we already know the stream pos!

* sqlite: Fix account data table in syncapi by commiting insert txns!

* sqlite: Fix failing federation invite

Was failing with 'database is locked' due to multiple write txns
being taken out.

* sqlite: Ensure we return exactly the number of events found in the database

Previously we would return exactly the number of *requested* events, which
meant that several zero-initialised events would bubble through the system,
failing at JSON serialisation time.

* sqlite: let's just ignore the problem for now....

* linting

This component roughly corresponds to "Client Room Send" and "Client Sync" on the WIRING diagram. This component produces multiple binaries.

Internals

  • HTTP routing is done using gorilla/mux and the routing paths are in the routing package.

Writers

  • Each HTTP "write operation" (/createRoom, /rooms/$room_id/send/$type, etc) is contained entirely to a single file in the writers package.
  • This file contains the request and response struct definitions, as well as a Validate() bool function to validate incoming requests.
  • The entry point for each write operation is a stand-alone function as this makes testing easier. All dependencies should be injected into this function, including server keys/name, etc.
