* Add const to several API functions that take char *.Jeremy Hylton2005-12-101-4/+6
| | | | | | | | | | | | | | | | | | | In C++, it's an error to pass a string literal to a char* function without a const_cast(). Rather than require every C++ extension module to put a cast around string literals, fix the API to state the const-ness. I focused on parts of the API where people usually pass literals: PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type slots, etc. Predictably, there were a large set of functions that needed to be fixed as a result of these changes. The most pervasive change was to make the keyword args list passed to PyArg_ParseTupleAndKewords() to be a const char *kwlist[]. One cast was required as a result of the changes: A type object mallocs the memory for its tp_doc slot and later frees it. PyTypeObject says that tp_doc is const char *; but if the type was created by type_new(), we know it is safe to cast to char *.

* Small function call optimization and special build option for call stats.Jeremy Hylton2003-02-051-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | -DCALL_PROFILE: Count the number of function calls executed. When this symbol is defined, the ceval mainloop and helper functions count the number of function calls made. It keeps detailed statistics about what kind of object was called and whether the call hit any of the special fast paths in the code. Optimization: When we take the fast_function() path, which seems to be taken for most function calls, and there is minimal frame setup to do, avoid call PyEval_EvalCodeEx(). The eval code ex function does a lot of work to handle keywords args and star args, free variables, generators, etc. The inlined version simply allocates the frame and copies the arguments values into the frame. The optimization gets a little help from compile.c which adds a CO_NOFREE flag to code objects that don't have free variables or cell variables. This change allows fast_function() to get into the fast path with fewer tests. I measure a couple of percent speedup in pystone with this change, but there's surely more that can be done.

* Part way to allowing "from __future__ import generators" to communicateTim Peters2001-07-161-1/+5
| | | | | | | | | | that info to code dynamically compiled *by* code compiled with generators enabled. Doesn't yet work because there's still no way to tell the parser that "yield" is OK (unlike nested_scopes, the parser has its fingers in this too). Replaced PyEval_GetNestedScopes by a more-general PyEval_MergeCompilerFlags. Perhaps I should not have? I doubted it was *intended* to be part of the public API, so just did.
* Revise the interface to the profiling and tracing support for theFred Drake2001-06-271-0/+3
| | | | | | | | | | | | | | | Python interpreter. This change adds two new C-level APIs: PyEval_SetProfile() and PyEval_SetTrace(). These can be used to install profile and trace functions implemented in C, which can operate at much higher speeds than Python-based functions. The overhead for calling a C-based profile function is a very small fraction of a percent of the overhead involved in calling a Python-based function. The machinery required to call a Python-based profile or trace function been moved to sysmodule.c, where sys.setprofile() and sys.setprofile() simply become users of the new interface.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* PyEval_SaveThread() and PyEval_RestoreThread() now return/take aGuido van Rossum1997-07-181-3/+6
| | | | | | | | | | | | | | | | PyThreadState pointer instead of a (frame) PyObject pointer. This makes much more sense. It is backward incompatible, but that's no problem, because (a) the heaviest users are the Py_{BEGIN,END}_ ALLOW_THREADS macros here, which have been fixed too; (b) there are very few direct users; (c) those who use it are there will probably appreciate the change. Also, added new functions PyEval_AcquireThread() and PyEval_ReleaseThread() which allows the threads created by the thread module as well threads created by others (!) to set/reset the current thread, and at the same time acquire/release the interpreter lock. Much saner.
