5888b03608 Fixed "historical" reference leak in TimestampFromTicks 
Added an internal function with C signature to avoid the creation of a
tuple to be later unpacked. When the tuple was decref'd, Python 2.4 64
bits regularly segfaulted; Python 2.5 less regularly; don't know about
other versions.

30921b58a8 Dropped conversion from None to NULL in adapter. 
It was an error as the string is not conform to the protocol. The error
is masked by the None fast path in _mogrify, but surfaces when adapting
a tuple contains a None.

ac25816962 Use the same Bytes_Format function for both Python 2 and 3. 
This makes the behaviour between the two versions similar. It also have
the effect of a more specific error message in case an user specifies a
placeholder different from 's'.

bc28cc8b00 Use unicode keys as strings in Py3. 
This fixes pyformat style argument passing. Unicode and bytes don't
compare equal (even if they hash the same).

Daniele Varrazzo
061079c918 In Py3, decode the tuple values before passing to the typecaster. 
Not sure this is the best way to go: it is now impossible to write a
binary typecaster in Python; furthermore it is the opposite approach of
the codecs, which should return bytes.

cb6b52945b The library can be compiled with Python 3. 
Just compiled! No test run yet and many points to review, marked in the
code.

The patch is largely Martin von Löwis work, simplified after refactoring
in the previous commits and adapted to the new code (as the patch was
originally for Psycopg 2.0.9)
 2010-12-21 04:24:36 +00:00

89f70bdb3c Changed Python const RO -> READONLY. 2010-12-12 13:39:32 +00:00
Daniele Varrazzo
6d7916cfe1 Internal imports simplified. 
.c files only need to import psycopg.h: it will in turn import
dependencies from Python and libpq and configure.h. psycopg.h should be
the first to be imported, so the basic imports are not required in
the .h's

As a guideline I'm trying to import from the most specific to the most
generic to detect missing imports in the .h's.

Daniele Varrazzo
557e28d744 Dropped interface for two private functions. 
Note: the functions are private because typecast.c imports the .c's of
typecast_[mx]datetime, not the .h's.

Work around the warning for 'skip_until_space' not used with an #ifdef.
Furthermore, those functions are now static.

e1a04bec0e Don't inconditionately run a query at connection to set datestyle to ISO.

something different.
 2010-11-16 18:15:00 +00:00
Daniele Varrazzo
15bba2966f Don't run a query at connection to detect client encoding. 
Use PQparameterStatus() instead. This is only guaranteed in protocol 3.
 2010-11-16 10:16:52 +00:00
Daniele Varrazzo
a88d7ab424 Dropped support for protocol 2. 
Dropped both the setup constant allowing conditional compiling and the
code specific to V2 protocol (mostly COPY and error handling).
 2010-11-16 01:08:50 +00:00
Daniele Varrazzo
73265e7ece Refuse connection with server with protocol version 2. 
This cuts off server whose version is older than 7.4. But enables us to
remove large portions of code rarely used and tested (e.g. p2 copy) and
will allow us to drop the query we do at each connection to establish
the client encoding and the datestyle.

Daniele Varrazzo
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).

bf1c76b792 Explicit cast of the SQL representation of time-related objects. 
Allow the objects to be recognized as the proper type by Postgres in not
strong contexts: problem reported by Peter Eisentraut.

Added tests to check the types are respected in a complete Py -> PG ->
Py roundtrip without context.

c8aef26e15 Adapt buffer objects using an explicit cast on the string literal. 
Don't rely on Postgres casting the literal according to the context:
this doesn't work e.g. passing the object as function argument where a
function with the same name but taking a text exists. It doesn't work
either when the object is in an ARRAY construct.

Added test to check the type is respected in a complete Py -> PG -> Py
roundtrip without context.

Bug and solution reported by Peter Eisentraut.

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).

Async mode and large object are not compatible, albeit I haven't found
an authoritative source yet.

a function that also checks for is presence and dismiss it after its
usage.

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
poll function: this is consistent with how the async branch is
implemented.

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

8fed0aa57d Forbid COPY-related methods in green mode. 
With the current implementation, at best they would silently block. They
actually hang everything.

Implementation posponed after some refactoring of the polling system,
because it will be probably possible to provide an implementation for
'poll()' during COPY which is good for both async and green modes.

0ec73a18b4 'pq_execute_command_locked()' calls the wait callback if set. 
The function is called without holding the GIL. Because it is necessary
to execute the Python callback if set, we need to re-acquire the GIL and
tnen release it again. In order to correctly bookkeep the thread state,
the pointer of the _save variable is passed to the function.
