Add warning mode for classic division, almost exactly as specified in PEP 238. Changes: - add a new flag variable Py_DivisionWarningFlag, declared in pydebug.h, defined in object.c, set in main.c, and used in {int,long,float,complex}object.c. When this flag is set, the classic division operator issues a DeprecationWarning message. - add a new API PyRun_SimpleStringFlags() to match PyRun_SimpleString(). The main() function calls this so that commands run with -c can also benefit from -Dnew. - While I was at it, I changed the usage message in main() somewhat: alphabetized the options, split it in *four* parts to fit in under 512 bytes (not that I still believe this is necessary -- doc strings elsewhere are much longer), and perhaps most visibly, don't display the full list of options on each command line error. Instead, the full list is only displayed when -h is used, and otherwise a brief reminder of -h is displayed. When -h is used, write to stdout so that you can do `python -h | more'. Notes: - I don't want to use the -W option to control whether the classic division warning is issued or not, because the machinery to decide whether to display the warning or not is very expensive (it involves calling into the warnings.py module). You can use -Werror to turn the warnings into exceptions though. - The -Dnew option doesn't select future division for all of the program -- only for the __main__ module. I don't know if I'll ever change this -- it would require changes to the .pyc file magic number to do it right, and a more global notion of compiler flags. - You can usefully combine -Dwarn and -Dnew: this gives the __main__ module new division, and warns about classic division everywhere else.

Mass checkin (more to follow for other directories). Introduce truly separate (sub)interpreter objects. For now, these must be used by separate threads, created from C. See Demo/pysvr for an example of how to use this. This also rationalizes Python's initialization and finalization behavior: Py_Initialize() -- initialize the whole interpreter Py_Finalize() -- finalize the whole interpreter tstate = Py_NewInterpreter() -- create a new (sub)interpreter Py_EndInterpreter(tstate) -- delete a new (sub)interpreter There are also new interfaces relating to threads and the interpreter lock, which can be used to create new threads, and sometimes have to be used to manipulate the interpreter lock when creating or deleting sub-interpreters. These are only defined when WITH_THREAD is defined: PyEval_AcquireLock() -- acquire the interpreter lock PyEval_ReleaseLock() -- release the interpreter lock PyEval_AcquireThread(tstate) -- acquire the lock and make the thread current PyEval_ReleaseThread(tstate) -- release the lock and make NULL current Other administrative changes: - The header file bltinmodule.h is deleted. - The init functions for Import, Sys and Builtin are now internal and declared in pythonrun.h. - Py_Setup() and Py_Cleanup() are no longer declared. - The interpreter state and thread state structures are now linked together in a chain (the chain of interpreters is a static variable in pythonrun.c). - Some members of the interpreter and thread structures have new, shorter, more consistent, names. - Added declarations for _PyImport_{Find,Fixup}Extension() to import.h.
