I just discovered that struct packs pointers from objects with an
__index__() method. Is that intentional?

 import struct
 class IDX(object):
... def __init__(self, value):
... self.value = value
... def __index__(self):
...  return self.value
... 
 struct.pack('P', IDX(9))
b'\t\x00\x00\x00\x00\x00\x00\x00'

[issue6715] xz compressor support

Nadeem Vawda nadeem.va...@gmail.com added the comment:

Ah, sorry about that. It probably wasn't necessary to regenerate the
patch after I addressed the comments in each review. The patch should be
stable now; I don't plan to make any further changes for a while.

(At some point I'll want to add a few more tests, and get the module to
compile on Windows. But that can wait.)

[issue12876] Make Test Error : ImportError: No module named _sha256


Wong Wah Meng wahm...@freescale.com added the comment:

I revert to this after I got my HP-UX ANSI-C compiler installed on my server 
(HP-UX 11.31 ia64). 

1.) Going back to SSL question, here is the software and version that is found 
on my server. I am not sure if this is the header only or the full file. 
However, since I am not using this module in my application, I am going to 
bypass correcting this error for time being:

  openssl -- A.00.09.08g.031 Secure Network Communications Protocol 
  fips_1_1_2 -- FIPS-OPENSSL-1.1.2.031 Secure Network Communications Protocol

2.) Ok I got my HP C compiler and the build outcome gives me more headaches. I 
am going to open a new thread of discussion just talk about the build options. 
Thanks guys for answering to this earlier. 

Regards,
Wah Meng

[issue12991] Python 64-bit build on HP Itanium - Executable built successfully but modules failed with HP Compiler

New submission from Wong Wah Meng wahm...@freescale.com:

Server Info: HP-UX B.11.31 Itanium ia64.
Evaluation copy is used however the license is being purchased, hopefully this
are not these errors are not caused by evaluation copy.

# swlist -l product | grep Compiler
ACXX C.06.26.EVAL HP C/aC++ Compiler
C-ANSI-C C.06.26.EVAL HP C/aC++ Compiler
COMPLIBS B.11.31Compiler Support Libraries

I encountered more failures in module build with my HP-UX ANSI C Compiler
versus gcc. I wonder why. I need a Oracle plug-in later, i.e. cx_Oracle and the
reason I do not want to ignore these errors now because I thought cx_Oracle
will have to (or, better) be built using HP compiler, not gcc for support from
Oracle.

I read through the README file, I followed the instruction to set the required
environment variables before the configure is run, and unset them before make
is run, also edited Makefile to remove Optimization and the -Olimit 1500.
However, it gives me a lot more modules that are failed to be built versus 2
when gcc is used. At the bottom of the mail we can see what failed to be built.

I have summarized my inquiry as follow:-
1.) Despite following the instruction to edit the Makefile before make is run,
I am surprise to see that the Makefile content is changed again when the
executable is generated. The changed I edited is restored. Is this expected and
did the compiler make use of the content that I edited when it did the build
and link?

$ diff Makefile Makefile_Original
61,62c61,62
OPT= -DNDEBUG -O
BASECFLAGS= +DD64 -Olimit 1500
---
OPT= -DNDEBUG
BASECFLAGS= +DD64

2.) A lot of failed module and I suspected it is due +DD64 nopt recognized by
the compiler. Why the HP-UX compiler did not recognize the option?

ld -b +DD64 -lxnet
build/temp.hp-ux-B.11.31-ia64-2.7/home/r32813/Build/2.7.1/Python-2.7.1/Modules/mathmodule.o

build/temp.hp-ux-B.11.31-ia64-2.7/home/r32813/Build/2.7.1/Python-2.7.1/Modules/_math.o
-L/usr/local/lib -lm -o build/lib.hp-ux-B.11.31-ia64-2.7/math.so
ld: Unrecognized argument: +DD64
Fatal error.

3.) This is a general question, in the README file there isn't specific
instruction on how to enable gcc for 64-bit build. Does gcc support 64-bit
build and how to?

4.) These are warning message. I have seen a lot of them. Am I right I can
ignore them? I don't see them when I use gcc though.

cc -Ae -c +DD64 -g -DNDEBUG -I. -IInclude -I./Include
-DPy_BUILD_CORE -o Modules/python.o ./Modules/python.c
Include/pyfpe.h, line 8: warning #3750-D: \ followed by white space is not

Thanks in advance for your input. Here is the output of my make using HP C
compiler.

[issue12974] array module: deprecate 'int' conversion support for array elements


Mark Dickinson dicki...@gmail.com added the comment:

Yes, that's intentional.  When use of __int__ was deprecated, a bug report 
popped up from someone who wanted to be able to have their own objects treated 
as integers for the purposes of struct.pack.  (I don't recall which issue;  
Meador, do you remember?)  So we added use of __index__ at that point.

I think __index__ is the right interface for something to expose if it wants to 
be usable as an integer, and this usage is consistent with the original 
__index__ PEP.

[issue12992] Python build finished, but the necessary bits to build these modules were not found: _tkinter


New submission from Wong Wah Meng wahm...@freescale.com:

Hello there,

I am building python on HP-UX 11.31 (Itanium ia64). I would like to utilize the 
_tkinter module in my application however I failed to build it. I think this 
module requires additional tcl + tk source code placed into certain directory 
and the configure will do the build accordingly. Can someone let me know what 
files are needed and where should I place them in terms of directory structure, 
so that I can build python with that built-in module successfully? Thanks!

(PS: I am able to build tcl tk 8.5.9 successfully on the same box however I am 
not sure how to link that piece of work into python build)

[issue12993] prepared statements in sqlite3 module

2011-09-16 Thread Mayur Angela Patel-Lam


New submission from Mayur  Angela Patel-Lam patel.lam.fam...@gmail.com:

The sqlite3 module is wonderful, but the one advantage that C/C++ coders have 
using that system is the ability to use precompiled/prepared SQL statements.  
Some SQL databases like Postgresql allow you to precompile statements using 
special SQL statements (e.g. PREPARE), so there is no need to change the python 
DBI for those database systems.  But unfortunately, sqlite3 only offers a C/C++ 
function, which returns a handle to the prepared statement.  I have sought a 
way to call this from the python DBI, but I simply don't think it's exposed.

Since my application interleaves several SQL commands, depending on the results 
of the last iteration, I can't immediately use executemany() to obtain maximum 
performance on my code.  Precompiled statements offer me the best opportunity 
to optimize.  I can prepare the 2 or 3 most expensive queries in my loop and 
call them in whatever order I need.  There are some estimates that prepared 
statements can accelerate complex queries by an order of magnitude, as the 
parser and optimizers don't need to come into play for every call.

Would you consider an extension to the sqlite3 DBI to expose prepared 
statements?  Thanks.

  So we added use of __index__ at that point.

Yes, I think that's #1530559, and the bug report was about PyCUDA. I can
see why 'bBhHiIlLqQ' allow __index__(), since they previously allowed
__int__().

I specifically meant the 'P' format. As far as I can see, PyLong_AsVoidPtr()
never allowed __int__(), but now index objects can be packed as pointers.
It isn't a big deal, I just have to know for features/pep-3118.

To illustrate, this is python2.5.0; INT is an object with an __int__() method:

'\x07\x00\x00\x00\x00\x00\x00\x00'
 struct.pack('P', INT(7))
Traceback (most recent call last):
  File stdin, line 1, in module
