Is there a way to use StringIO buffer like pipe with lazy write? Is there a way to hook a function to be called when End Of File/String occurs on the StringIO object to append next lines that can be read? Already read lines should by disposed.
Or is available another object/library like StringIO? I don't want to use the operating system pipes and forking. I need to foist a file-like buffer to psycopg2.copy_from() but with behaviour like pipe.
Something like Efficient FIFO queue for arbitrarily sized chunks of bytes in Python and deque but line oriented.
