Always defer *sql.Rows.Close and consult with Err (#844)
* Always defer *sql.Rows.Close and consult with Err

database/sql.Rows.Next() makes sure to call Close only after exhausting
result rows which would NOT happen when returning early from a bad Scan.
Close being idempotent makes it a great candidate to get always deferred
regardless of what happens later on the result set.

This change also makes sure call Err() after exhausting Next() and
propagate non-nil results from it as the documentation advises.

Closes #764

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.
