61e52ce879 Rework replication protocol 
This change exposes lower level functions for operating the
(logical) replication protocol, while keeping the high-level
start_replication function that does all the job for you in
case of a synchronous connection.

A number of other changes and fixes are put into this commit.

e32e1b834e Add support for streaming replication protocol 
Introduce ReplicationConnection and ReplicationCursor classes, that
incapsulate initiation of special type of PostgreSQL connection and
handling of special replication commands only available in this special
connection mode.

The handling of stream of replication data from the server is modelled
largely after the existing support for "COPY table TO file" command and
pg_recvlogical tool supplied with PostgreSQL (though, it can also be
used for physical replication.)

d66165232e OpenSSL deadlock fix noted in NEWSfile 2015-05-03 12:27:37 +01:00
Jan Urbański
a59704cf93 Make sure libcrypto threadsafety callbacks are properly set up 
Multithreaded programs using libcrypto (part of OpenSSL) need to set up
callbacks to ensure safe execution. Both Python and libpq set up those
callbacks, which might lead to a conflict.

To avoid leaving dangling function pointers when being unloaded, libpq sets up
and removes the callbacks every time a SSL connection it opened and closed. If
another Python thread is performing unrelated SSL operations (like connecting
to a HTTPS server), this might lead to deadlocks, as described in
http://www.postgresql.org/message-id/871tlzrlkq.fsf@wulczer.org

Even if the problem will be remediated in libpq, it's still useful to have it
fixed in psycopg2. The solution is to use Python's own libcrypto callbacks and
completely disable handling them in libpq.
