[Guido van Rossum]

Update of /cvsroot/python/python/dist/src/Demo/embed
In directory usw-pr-cvs1:/tmp/cvs-serv2697

Modified Files:
	Makefile README 
Added Files:
	loop.c 
Log Message:
Add loop.c -- a test program for repeatedly calling Py_Initialize()
and Py_Finalize().  It seems to dump core right now...


--- NEW FILE: loop.c ---
/* Simple program that repeatedly calls Py_Initialize(), does something, and
   then calls Py_Finalize().  This should help finding leaks related to
   initialization. */

		fprintf(stderr, "usage: loop <python-command>\n");
		exit(2);

	Py_SetProgramName(argv[0]);

	while (1) {
		Py_Initialize();
		PyRun_SimpleString(command);
		Py_Finalize();

+ 
+ An additional test program, loop.c, is used to experiment with memory
+ leakage caused by repeated initialization and finalization of the
+ interpreter.  It can be build by saying "make loop" and tested with
+ "make looptest".  Command line usage is "./loop <python-command>",
+ e.g. "./loop 'print 2+2'" should spit out an endless number of lines
+ containing the number 4.
