Subject: [capi-sig] Triggering a KeyboardInterrupt in a PyObject_CallObject
Message-ID: <5BF122F9-EC04-430F-A45E-A273B72B26F1@apple.com>

Hi list.
I have a situation where I make a PyObject_CallObject call on one thread, and then I watch for keyboard input on a separate thread.
When the user hits CTRL-C, this second thread will see it and needs to make it so that the callable being run on the first thread gets "stopped" with a KeyboardInterrupt exception
I tried calling Py_AddPendingCall() on the second thread, and passing it a pointer to a function foo.

My first attempt was to make foo call PyErr_SetInterrupt() and PyErr_CheckSignals().

Since this did not work, I rewrote foo to explicitly set the KeyboardInterrupt exception with PyErr_SetString() and returning -1
This worked in the sense that I saw the KeyboardInterrupt come out on screen as a traceback, but it did not stop the function from running.

Am I doing something wrong? Is there even a way to raise an exception "inside" a PyObject_CallObject without the callee doing anything?
It would be much preferable that the called python object did not have to do anything in order to be interruptible, but I would be willing to compromise on some simple "make me interruptible" pattern, provided it really is simple.

Thanks for any help.

Maybe this is what you're looking for:

Tho, I'm not sure if it's a good idea for your particular case?

This depends a bit on what the library expects as input elsewhere and
whether the memory area allocation is being managed elsewhere or not.

You could use a PyBuffer_FromReadWriteMemory() or a PyString_FromStringAndSize()
with Python 2.4.

Subject: [capi-sig] Embedded Python seems broken on Mac OS X Mountain LIon
Message-ID: <50886465.50208@llnl.gov>

I am trying to work with Apple Mountain Lion's install of Python 2.7. I 
have a language interoperability tool, Babel 
http://www.llnl.gov/CASC/components/, that used embedded Python when 
other languages are calling Python (c.g., C++ calling Python). My 
fundamental problem is that sys.path is not being initialized the same 
when I dlopen(libpython2.7.dylib) and initialize Python compared with 
how the sys.path is set when the Python executable is called directly. 
This causes Python to fail to load the numpy module used by Babel.

bash-3.2$ /usr/bin/python2.7 -c "import sys; print sys.path; import 
numpy" > /tmp/out1
bash-3.2$ /usr/bin/python -c "import sys; print sys.path; import numpy" 
 > /tmp/out2
bash-3.2$ cat /tmp/out1

Presumably, this C program that uses dlopen(), Py_Initialize, and 
Py_SimpleString should have exactly the same output.

/** foo.c */
#include <dlfcn.h>
#include <stdio.h>

int
main(int argc, char **argv)
{
   // void *lptr = 
dlopen("/System/Library/Frameworks/Python.framework/Python", RTLD_NOW | 
RTLD_GLOBAL);
   void *lptr = 
dlopen("/System/Library/Frameworks/Python.framework/Versions/2.7/lib/libpython2.7.dylib", 
RTLD_NOW | RTLD_GLOBAL);
   if (lptr) {
     void (*pyinit)(void) = dlsym(lptr, "Py_Initialize");
     if (pyinit) {
       int (*runSimple)(const char *);
       (*pyinit)();              /* initialize Python */
       runSimple = dlsym(lptr, "PyRun_SimpleString");
       if (runSimple) {
         (*runSimple)("import sys ; print sys.path; import numpy");
       }
     }
     else {
       fprintf(stderr, "Unable to locate Py_Initialize: %s\n", dlerror());
     }
   }
   else {
     fprintf(stderr, "Error loading Python shared library: %s\n", 
dlerror());
   }
}

bash-3.2$ gcc foo.c ; ./a.out
['/usr/lib/python27.zip', '/usr/lib/python2.7', 
'/usr/lib/python2.7/plat-darwin', '/usr/lib/python2.7/plat-mac',

'/usr/lib/python2.7/lib-old', '/usr/lib/python2.7/lib-dynload']
Traceback (most recent call last):
   File "<string>", line 1, in <module>
ImportError: No module named numpy

However as you see, it has a completely different sys.path. I can't seem 
to find a way to get it to initialize Python with the same sys.path. It 
seems like the libpython2.7.dylib is broken. I am at a loss on how to 
fix this or even who to ask for help.

Tom Epperly

Subject: [capi-sig] Universal setter function not in docs?
Message-ID: <CAL-VaPfW-Wsb4O0Op8GpDszCeEO+68bLaU7=sLR3Er0Z7wGh8g@mail.gmail.com>

Hello Gang, I am fresh to this list so, hello gang!
========================================
I have the need for a universal setter function to set objects.
The documentation suggests that there is a way to use a void pointer
to define object data for comparison. Unfortunately, there does not
seem to be any examples on how to do this.

This snippet only works with the `last` attribute of the object -->

static int
Noddy_setlast(Noddy *self, PyObject *value, void *closure)
{
  if (value == NULL) {
    PyErr_SetString(PyExc_TypeError, "Cannot delete the last attribute");
    return -1;
  }
  if (! PyString_Check(value)) {
    PyErr_SetString(PyExc_TypeError,
                    "The last attribute value must be a string");
    return -1;
  }
  Py_DECREF(self->last);
  Py_INCREF(value);
  self->last = value;
  return 0;
}

Is there any examples of a universal setter function for
`PyGetSetDef` that would check a attribute type with the 3 argument in
 Noddy_setlast?
Thank you.

*From the docs* [http://docs.python.org/extending/newtypes.html]
> `The getter function is passed a Noddy object and a ?closure?, which is void pointer. In this case, the closure is ignored. (The closure supports an advanced usage in which definition data is passed to the getter and setter. This could, for example, be used to allow a single set of getter and setter functions that decide the attribute to get or set based on data in the closure.)`

You are not very clear about what you want to achieve. What's "universal" 
about that setter function? Could you give an example?

For an example of getset using the 3rd argument, sometimes I use this
so single get/set functions can be used to access different flags.

Message-ID: <CAL-VaPco9VpQB+Hy-cskKOBA6gGNOJopeF02U4naiu=NQFCryg@mail.gmail.com>

Hello Gang, I am asking that one of you can point me into the correct direction.
I have a python module which has two objects with many methods and
attributes in each.
The two hypothetical objects are "house" and "tree".
E.g. Used like below:
import my_mod
h = my_mod.house()
t = my_mod.tree()

They also contain attributes like:
h.color
t.height


I would like to pass the t object to a house.attach() method
e.g. h.attach(t)
and modify the attributes of t within the house object methods. What
is the best practice to reference separate objects in a module
which are passed in at the interpreter? Any thoughts are appreciated
as keywords and ideas
are easy to Google.

Thank you, Robert.

Alright, disregard this message. This appears to be easy enough with
the use structs.
