Apparently the cgo typechecks get better on tip, so use C.int instead
of Go integers.
Build tip as part of the Travis build, so we can ensure that any
errors are resolved before they get released to a wider audience.
sql.Driver, sql.Conn, sql.Tx sql.Stmt, and sql.Rows are not interfaces.
Updated the comments to refer to the correct interfaces: driver.Driver,
driver.Conn, driver.Tx, driver.Stmt, and driver.Rows.
Because the closed property of the SQLiteRows's *SqliteStmt
was not guarded, it was causing an issue during context
cancellation.
be424d27ac/sqlite3.go (L1785-L1796)
When a statement is performing a query(), if it determines that
the context has been canceled, it will launch a goroutine that
closes the resulting driver.Rows if it's not already completed.
If the driver.Rows is not done (and the context has been canceled),
it will interrupt the connection and more importantly, perform
a rows.Close(). The method rows.Close() guards the closed bool with
a sync.Mutex to set it to true.
If a reader is reading from the SqliteRow, it will call Next()
and that performs this check:
be424d27ac/sqlite3.go (L1915-L1917)
Because this is not guarded, a data race ensues, and this was
actually caught by the Go race detector recently.
I didn't include a test case here because the fix seemed
straightforward enough and because race conditions are hard
to test for. It's been verified in another program that this
fixes the issue. If tests should be provided I'm more than
happy to do so.
