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.
- 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.
The value is used to control the number of records to fetch per network
roundtrip in named cursors iteration. Used to avoid the inefficient
arraysize default of 1 without giving this value the magic meaning of
2000.
Failing to do so, the real cause of the _psycopg import failed may get
hidden and people may get a misleading error such as "cannot import name
tz" instead.
Supporting this interface is required to adapt memoryview on Python 2.7 as they
don't support the old style. But because the old style is long deprecated it
makes sense to start supporting the new one.
The feature in itself is not extremely useful and instead PostgreSQL is
not always able to cast away from text[], which is a regression see
(ticket #42).
With test_concurrent_execution test, checking two threads issuing a pg_sleep
of 2 seconds and and check if they complete in under 3 seconds occasionally
fails when the test is run in a virtual machine on a VM Server with other
virtual machines running. Increased the sleep to 4, and the check to 7,
giving 3 seconds buffer instead of 1 second.
Initial compiler check was only checking two python versions. Changed the
check not to check python version, but compiler version, to be compatible
with more versions of python.
Windows is not able to create a tempfile with NamedTemporaryFile and then
open it with a second file handle without closing the first one. Added
code to close the handle, and keep the file around a little longer so it
can be reopened and rewritten to again.
Apparently, using * for the architecture has the potential to not work on
on some amd64 systems. Added checks and split the manifest based upon
architecture.
Added a change at the end of the build process that would reinsert the VC library manifest. This patch will fix issues when an embedded program does not have a manifest pointing to the VC 2008 runtime library, such as in an apache/mod_python situation.
