DbPool

Create a connection pool.

Get the pool name.

Get a connection from the pool.

Release a connection back to the pool.

Discard a borrowed connection from the pool.

Close idle connections while the total managed count exceeds the configured minimum.

Check one idle connection and discard it when unhealthy.

Close the database pool and clear its shared resources.

Determine if the pool is closed.

Get the current number of connections managed by the pool.

Get the pool configuration options.

Get the number of connections currently available in the pool.

Initialize pool options from configuration.

Create a new pooled connection.

Pop and validate one idle connection.

Return an idle connection without changing its activity timestamps.

Destroy a managed connection and release its capacity.

Report a pool maintenance or cleanup failure without throwing.

Get the logger instance if available.

Convert seconds to nanoseconds without overflowing integer arithmetic.

Build a monotonic deadline without overflowing at long durations or uptimes.

Get the shared PDO for in-memory SQLite, or null for other drivers/configurations.

Create the shared PDO for in-memory SQLite via the factory.

Uses the normal factory pipeline to get all config parsing, driver extensions, and connection setup. We then extract the PDO and let the Connection object be garbage collected.

Check if this pool is for an in-memory SQLite database.

Ensure a derived read pool does not point at an in-memory SQLite database.

Start the heartbeat timer if configured.

Clear the heartbeat timer.

Run one heartbeat sweep over currently idle connections.
