I've answered him personally about the first part -- but the second part is interesting (and even troubling)

Hi,

when I compile version 1.6b1 on HP-UX-10, I get a few compilation errors in Python/getargs.c (undefined UCHAR_MAX etc). The following patch fixes this:

*** Python/getargs.c.orig Mon Aug 7 10:19:55 2000 --- Python/getargs.c Mon Aug 7 10:20:21 2000 *************** *** 8,13 **** --- 8,14 ---- #include "Python.h"
#include <ctype.h> + #include <limits.h>

int PyArg_Parse Py_PROTO((PyObject *, char *, ...));

I also have a suggestion to improve the speed on the HP-UX platform. By tuning the memory allocation algorithm (see the patch below), it is possible to obtain a speed improvement of up to 22% on non-trivial Python scripts, especially when lots of (small) objects have to be created. I'm aware that platform-specific features are undesirable for a multi-platform application such as Python, but 22% is quite a lot for such a small modification ... Maybe similar tricks can be used on other platforms too.

*** Modules/main.c.orig Mon Aug 7 10:02:09 2000 --- Modules/main.c Mon Aug 7 10:02:37 2000 *************** *** 83,88 **** --- 83,92 ---- orig_argc = argc; /* For Py_GetArgcArgv() / orig_argv = argv;
+ #ifdef __hpux + mallopt (M_MXFAST, 512); + #endif / __hpux */ + if ((p = getenv("PYTHONINSPECT")) && *p != '\0') inspect = 1; if ((p = getenv("PYTHONUNBUFFERED")) && *p != '\0')

Regards,

Eddy
