Summary: failed to load tuxedo libs
Initial Comment:
we have a tuxedo(BEA) python extension, the extension
works very well under solaris/AIX, it has issue with
HPUX(PA-RISC or ITANINM)
with python 2.3.2 and 2.3.5

_tuxedowsnmodule.so is our python interface lib,
from 'ldd -r' output, the lib itself should not have
any issue,
but when we tried to load it to python, it complained,

(/usr/lib/hpux64/libc.so.1)
we looked at the python source code, and think we
found the cause of the issue:
case $ac_sys_system/$ac_sys_release in
AIX*) DYNLOADFILE="dynload_aix.o";;
BeOS*) DYNLOADFILE="dynload_beos.o";;
hp*|HP*) DYNLOADFILE="dynload_hpux.o";;
Darwin/*) DYNLOADFILE="dynload_next.o";;
atheos*) DYNLOADFILE="dynload_atheos.o";;
*)
# use dynload_shlib.c and dlopen() if we have it;
otherwise stub
# out any dynamic loading
if test "$ac_cv_func_dlopen" = yes
then DYNLOADFILE="dynload_shlib.o"
else DYNLOADFILE="dynload_stub.o"
fi
where on hpux the file dynload_hpux is used. Looking
inside Python/dynload_hpux.c;
flags = BIND_FIRST | BIND_DEFERRED;
if (Py_VerboseFlag) {
flags = BIND_FIRST | BIND_IMMEDIATE |
BIND_NONFATAL | BIND_VERBOSE;
printf("shl_load %s\n",pathname);
}
lib = shl_load(pathname, flags, 0);
/* XXX Chuck Blake once wrote that 0 should be
BIND_NOSTART? */
if (lib == NULL) {
char buf[256];
if (Py_VerboseFlag)
perror(pathname);
PyOS_snprintf(buf, sizeof(buf), "Failed to load
%.200s",
pathname);
PyErr_SetString(PyExc_ImportError, buf);
return NULL;
}
We looked through the shl_load man page and found
that Python should be using the option
BIND_TOGETHER. I tried it and it loads the tuxedo
module.
shl_load man page;
BIND_TOGETHER When used with BIND_FIRST, the
library being mapped and its dependent libraries will
be bound together. This is the default behavior for
all shl_load() requests not using BIND_FIRST.
So we changed the /Python-
2.3.2/Python/dynaload_hpux.c to;
flags = BIND_FIRST | BIND_DEFERRED |
BIND_TOGETHER;
if (Py_VerboseFlag) {
flags = BIND_FIRST | BIND_IMMEDIATE |
BIND_TOGETHER |
BIND_NONFATAL | BIND_VERBOSE;
printf("shl_load %s\n",pathname);
}
Not sure if there is version of python without the
bug, and if it is possible to patch 2.3.2 and 2.3.5
OS tested:
B.11.23 U 9000/800 (PA-RISC and ITANIUM)
