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.)

6c57e4a648 Add parse_dsn module function
Calls PQconninfoParse to parse the dsn into a list of keyword and value
structs, then constructs a dictionary from that.  Can be useful when one
needs to alter some part of the the connection string reliably, but
doesn't want to get into all the details of parsing a dsn string:
quoting, URL format, etc.

d66165232e OpenSSL deadlock fix noted in NEWSfile 2015-05-03 12:27:37 +01:00

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.

296caa4556 More tests tweaks
Named cursors on old server versions have a different prefetch behaviour.
This has hidden me the supported range of the 24:00 time format.
Let's have another go at full testing...

5af5fb4cc6 Allow pickling of cursor.description
This is for people using dtuple.py; a dtuple.DatabaseTuple instance
keeps a reference to cursor.description, which is not picklable because
psycopg2 doesn't export the Column namedtuple it uses.

This commit exports the Column namedtuple, and includes a test to verify
the pickle/unpickle works after exporting Column.

e490e3bfa3 Accept overflow errors testing for LO64 funcs
It is raised on 32 bits by PyArg_ParseTuple. We may work around on
truncate (maybe parsing a py_ssize_t) but we would have the same problem
on seek as the offset is signed.

2f862972c9 Guard against overflows when using the lo32 api
If psycopg supports lo64 but the server doesn't the user may pass values
that would overflow the api range, resulting in:

    lo.seek((2<<30))
    *** OperationalError: ERROR:  invalid seek offset: -2147483648

Also improved the error messages and guard against INT_MIN for negative
seek offsets.
