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.
* User Authentication Implementation
* Rename file to conform to fileformat `sqlite3_*_omit.go`
* Updated sqlite3-binding.* with new upgrade tool
* Add: callbackRetNil required for error type return because of adding `RegisterFunc`s directly on the connection.
* Add: TestCreateAuthDatabase
* Conform keys to match PRAGMA
* UPD: README
* Fix error of _auto_vacuum
* Fix error of _case_sensitive_like
* Fix error of _locking_mode
* Fix error of _secure_delete
Fix: Placed all +build tags in the same location
Fix: Split CFLAGS, LDFLAGS into seperate lines for readability and lookup
Fix: Placed empty line between copyright comments and build tags for readability
Fix: Placed OS specfic cgo flags at the end if the cgo sections contains multiple lines.
