Guido van Rossum 2c69336507 On second though, NEXITFUNCS should be defined in pythonrun.c and not
here; pystate.h doesn't use it (I thought I wanted to move the array
there but that won't work).

Guido van Rossum ee0a63bec5 Move 'dict' struct member to end of struct. This ensures binary
compatibility for shared libraries.

Guido van Rossum 204751b127 Add dict struct member and PyThreadState_GetDict() prototype. 1998-04-10 20:19:01 +00:00
Guido van Rossum 29e46a9a12 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.

Guido van Rossum 59943ba718 Added Py_PROTO macros for SunOS 4.x /bin/cc. 1997-05-20 22:07:46 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.
