Example #3

File: xid_type.c Project: psycopg/psycopg2

/* Return the PostgreSQL transaction_id for this XA xid.
 *
 * PostgreSQL wants just a string, while the DBAPI supports the XA standard
 * and thus a triple. We use the same conversion algorithm implemented by JDBC
 * in order to allow some form of interoperation.
 *
 * The function must be called while holding the GIL.
 *
 * see also: the pgjdbc implementation
 *   http://cvs.pgfoundry.org/cgi-bin/cvsweb.cgi/jdbc/pgjdbc/org/postgresql/xa/RecoveredXid.java?rev=1.2
