4dbda02145 Cast time into timetz when the tzinfo field is set. 2014-11-13 17:32:06 +09:00
Daniele Varrazzo
1b48033345 Don't try to close the server cursor in error state 
`close()` is implicitly called by `__exit__()`, so an exit on error
would run a query on a inerr connection, causing another exception
hiding the original one. The fix is on `close()`, not on `__exit__()`,
because the semantic of the latter is simply to call the former.

Closes #262.

2d601ef157 Fixed memory leak with large objects 
Deallocating closed large objects failed to decrement the connection
refcount. The fact the lobject is closed doesn't matter for refcount.
Issue detected by the always useful scripts/refcounter.py

With an extra bit of unrequested whitespace love.

54d904138d Don't import psycopg2.tz into the C extension 
This makes possible to import _psycopg directly, after adding the
package directory to the pythonpath. This enables hacks such as:

    sys.path.insert(0, '/path/to/psycopg2')
    import _psycopg
    sys.modules['psycopg2._psycopg'] = _psycopg
    sys.path.pop(0)

which can work around e.g. the problem of #201, freeze that cannot
freeze psycopg2. Well, freeze cannot freeze it because it's just not
designed to deal with C extensions. At least now the frozen application
can hack the pythonpath and work around the limitation by importing
_psycopg as above and then doing the rest of the imports normally.

Keeping long-lived references to python objects is bad anyway: the
tz module couldn't be reloaded before.

1d729ab40e Dropped HAVE_PQFREEMEM flag

68a4308c3d Dropped PSYCOPG_NEW_BOOLEAN flag 
Introduced in 2.0 beta 8, 2006 A.D. Went absolutely untouched in 8 years
of refactoring, when Python 2.5 and PostgreSQL 8.1 roamed the earth.

I would say it has stood the test of the time.

6e841a41e6 Dropped PSYCOPG_EXTENSIONS flag 
Building without extensions has been long broken and nobody really cares
about a pure-DBAPI implementation (which could be created using a wrapper
instead).

Also, don't start an implicit transaction when fetching with

a2b01cdf42 Dropped simple type wrapper functions 
These functions don't need to exist: exposing the type in the module is
enough. It is actually better as one may use isinstance and such.

<TypeName object at 0xADDR>.

they deserve it.

connection closed.

3b8abf3fc4 Clean the C members of Error in tp_dealloc instead of tp_clear 
tp_clear should only be used to break the reference cycles. tp_clear was
causing a segfault because it was called twice (by the gc and by _dealloc) so
self->codec was freed twice.

Amazingly the double free was only causing a segfault on Python 3.3 (released
in late 2012) talking to Postgres 8.1 (released in 2005) in async mode... no
other combination crashed. Thank you buildbot.

53b1c70f3a Attempt to fix issue #113. 
If the network is down, trying to read blocking will hang the process hard
(ctrl-c not working). Send a cancel signal instead (as suggested in
http://archives.postgresql.org/pgsql-hackers/2012-07/msg00903.php) and go
back into a green polling: this should allow a further error (e.g. another
ctrl-c) to break the loop. In this case we cannot assume anything about
the state of the connection, so we close it.

The function is always called in the context of functions grabbing the

(ticket #55) as the notices are a psycopg structure, not libpq. However the
change allows again processing notices/notifies in the same place,
which makes sense conceptually, plus we save some lock dance.

The encoding can be set by PGCLIENTENCODING, which may be an alternative

At this point the idea of considering one of the random spellings such as
EUC_CN as somewhat "blessed" is debunked. So just store the cleaned-up
version of the encoding in the mapping table. Note that the cleaned-up
version was needed by the unicode adapter: this requirement has been
surpassed as the connection now contains a copy of the Python codec name
set whenever the client encoding is set.

4bc47d47a5 Python 3.2 hash() return value is arch dependant 
Python 3.2 hash() function will now return a 64bit value when run on a 64bit
architecture, where as previously, it would always return a 32bit value.
Modified the code to use the now Py_hash_t typedef and for Python versions
less than 3.2, hard code Py_hash_t to long and Py_uhash_t to unsigned long.

99b3c72312 Some cleanup in mogrify 
- Raise an exception on incomplete placeholders.
- Minor speedups.
- Don't change the string in place (??!!) if the placeholder is not s
  and the value is null.

The latter point can be done because downstream we don't accept anything
different from s anyway (in the Bytes_Format function).

Notice that now the format string is constant whatever the arguments.
This means that executemany is still more inefficient than it should be
as mogrify may work only on the parameters. However this is an
implementation only worthwhile if we start supporting real parameters.

Let's talk about that for the next release.

Daniele Varrazzo
77c0ab02d8 The Notify type is hashable. 
If there is no payload, hash the same way the equivalent 2-tuple does.
Otherwise hash on the payload too.

9c58c01e0f Added comparison between Notify objects and Notify or tuple. 
Explicit comparison with the tuple is required if we want to make
Notify() == (pid, channel) work: item access is not enough (and a test
in the suite fails if we get this wrong).

either when the object is in an ARRAY construct.

roundtrip without context.

73db6bee01 Keep the connection in blocking mode unless it is not async. 
Dropped set/unset nonblocking mode for copy and lobject operations:
lobjects don't work in nonblocking mode so they will hardly be supported
in green/async branches.  Support for copy is still feasible, but it
will be done in other code paths (called by poll).

7af0bf0b54 Set the async_status to ASYNC_DONE after a query with wait callback. 
Failing in doing that broke notifications reception.

The responsibility for changing the async_status has been moved to the

implemented.

With this commit all the test suite passes in "green" mode.
