- New functions (each accepts a pgsql $connection resource):
. pg_connect_poll
. pg_socket
. pg_consume_input
. pg_flush
- Modified functions
The following functions now additionally return zero if the
underlying socket is set to non-blocking mode and the send
operation does not complete immediately. Previously these
functions returned only boolean TRUE/FALSE and blocked
execution while polling until all data was sent:
. pg_send_execute
. pg_send_prepare
. pg_send_query
. pg_send_query_params
- New constants
Used with pg_connect() to initiate an asynchronous connection
attempt:
. PGSQL_CONNECT_ASYNC
Used with pg_connection_status() to determine the current state
of an async connection attempt:
. PGSQL_CONNECTION_STARTED
. PGSQL_CONNECTION_MADE
. PGSQL_CONNECTION_AWAITING_RESPONSE
. PGSQL_CONNECTION_AUTH_OK
. PGSQL_CONNECTION_SSL_STARTUP
. PGSQL_CONNECTION_SETENV
Used with pg_connect_poll() to determine the result of an
async connection attempt:
. PGSQL_POLLING_FAILED
. PGSQL_POLLING_READING
. PGSQL_POLLING_WRITING
. PGSQL_POLLING_OK
. PGSQL_POLLING_ACTIVE
- Polling via returned pg_socket() stream
pg_socket() returns a read-only socket stream that may be
cast to a file descriptor for select (and similar) polling
operations. Blocking behavior of the pgsql connection socket
can be controlled by calling stream_set_blocking() on the
stream returned by pg_socket().
