PyEval_EvalCode()
by Tino Lange Oct. 17, 2002

Oct. 17, 2002

Hi! This prototype is not available when including "Python.h" (Using v2.1.3) Why did you exclude it from the "official" API prototypes? I found it in "eval.h", which has to be included manually, besides "Python.h". Isn't that PyEval_EvalCode() the regular API function to run CodeObjects from Py_CompileString() ? Cheers, Tino

Dropping support for Tcl 8.0 and 8.1
by Martin v. Loewis Oct. 17, 2002

Oct. 17, 2002

In _tkinter.c, there is currently special code for Tcl 8.0 (no Tcl objects) and Tcl 8.1 (no Unicode type). Tcl 8.2, 8.3, and 8.4 are supported uniformly. Can we drop support for those two releases, in Python 2.3? Regards, Martin

Memory size overflows
by Armin Rigo Oct. 16, 2002

Oct. 16, 2002

Hello everybody, All around the C code there are potential problems with objects of very large sizes (http://www.python.org/sf/618623). The problem is that to allocate a variable-sized object of type 't' with 'n' elements we compute 'n*t->tp_itemsize', which can overflow even if 'n' is a perfectly legal value. If the truncated result is small, the subsequent malloc() suceeds, and we run into a segfault by trying to access more memory than reserved. The same problem exists at other places … [View More]

buffer('abc') == 'abc' is False ?!
by M.-A. Lemburg Oct. 16, 2002

Oct. 16, 2002

I was wondering whether this is an oversight or intended. Buffer objects can certainly be compared to strings on a byte-by-byte basis, so the compare result looks like a (long standing) bug to me. -- Marc-Andre Lemburg CEO eGenix.com Software GmbH _______________________________________________________________________ eGenix.com -- Makers of the Python mx Extensions: mxDateTime,mxODBC,...

Stackless for 2.2.2 ready!
by Christian Tismer Oct. 16, 2002

Oct. 16, 2002

Hi Python-community, The Stackless Python beta has been ported to the Python 2.2.2 release, one day after the announce. It could have been even faster, but I had to work a lot on typeobject.c, which had been backported from 2.3. My own patches to that are now very tiny and will be submitted, soon. Changes to Stackless: The option to build statically has been re-enabled. Supported platforms are now Windows, Mac OS X, Linux-X86, Cygwin, SunOS Sparc with gcc, PPC Unix, S390 & … [View More]

[win32] Killing MSVC's _alloca
by Gerhard Haering Oct. 15, 2002

Oct. 15, 2002

Trying to get around to my mingw32 port again. I currently don't have Visual C++ installed, but why is this nonstandard _alloca needed? Can't it simply be replaced by alloca? Doesn't MSVC have alloca? For the moment, I'm as far as building posixmodule.c, which I succeeded by doing a #define _alloca alloca If there's a way to kill MSVC peculiarities, could this please be done? -- Gerhard

(Jack, mail me ASAP if you do!) I realize this is a little late, but I was wondering if 2.2.2 will support VC7 (important for us Python-in-a-tie people ;-) I searched the mailing list, but the only thing I found were messages that it was fixed on the 2.3 branch... -- bjorn
