* Revert the previous enhancement to the bytecode optimizer.Raymond Hettinger2003-04-241-2/+0
| | | | The additional code complexity and new NOP opcode were not worth it.
* Improved the bytecode optimizer.Raymond Hettinger2003-04-221-0/+2
| | | | | | | | | | | | | | * Can now test for basic blocks. * Optimize inverted comparisions. * Optimize unary_not followed by a conditional jump. * Added a new opcode, NOP, to keep code size constant. * Applied NOP to previous transformations where appropriate. Note, the NOP would not be necessary if other functions were added to re-target jump addresses and update the co_lnotab mapping. That would yield slightly faster and cleaner bytecode at the expense of optimizer simplicity and of keeping it decoupled from the line-numbering structure.
* New PyGILState_ API - implements pep 311, from patch 684256.Mark Hammond2003-04-192-0/+48

* _Py_PrintReferences(): Changed to print object address at start of eachTim Peters2003-04-171-0/+1
| | | | | | | | | | | | | | | new line. New pvt API function _Py_PrintReferenceAddresses(): Prints only the addresses and refcnts of the live objects. This is always safe to call, because it has no dependence on Python's C API. Py_Finalize(): If envar PYTHONDUMPREFS is set, call (the new) _Py_PrintReferenceAddresses() right before dumping final pymalloc stats. We can't print the reprs of the objects here because too much of the interpreter has been shut down. You need to correlate the addresses displayed here with the object reprs printed by the earlier PYTHONDUMPREFS call to _Py_PrintReferences().
* SF # 595026: support for masks in getargs.c.Thomas Heller2003-04-172-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New functions: unsigned long PyInt_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyInt_AsUnsignedLongLongMask(PyObject *); unsigned long PyLong_AsUnsignedLongMask(PyObject *); unsigned PY_LONG_LONG) PyLong_AsUnsignedLongLongMask(PyObject *); New and changed format codes: b unsigned char 0..UCHAR_MAX B unsigned char none ** h unsigned short 0..USHRT_MAX H unsigned short none ** i int INT_MIN..INT_MAX I * unsigned int 0..UINT_MAX l long LONG_MIN..LONG_MAX k * unsigned long none L long long LLONG_MIN..LLONG_MAX K * unsigned long long none Notes: * New format codes. ** Changed from previous "range-and-a-half" to "none"; the range-and-a-half checking wasn't particularly useful. New test test_getargs2.py, to verify all this.
* - New C API PyGC_Collect(), same as calling gc.collect().Guido van Rossum2003-04-171-0/+3
| | | | | - Call this in Py_Finalize(). - Expand the Misc/NEWS text on PY_LONG_LONG.
* Changes from Jonathan Riehl to allow his pgen extension (PEP 269) toGuido van Rossum2003-04-172-0/+22
| | | | | | work. This includes some more code that used to be part of pgen in the main parser; I'm okay with that. I'll see if the Windows build needs work next.
* - New function sys.call_tracing() allows pdb to debug codeGuido van Rossum2003-04-091-0/+2
| | | | | | recursively. - pdb has a new command, "debug", which lets you step through arbitrary code from the debugger's (pdb) prompt.

* Improved new Py_TRACE_REFS gimmicks.Tim Peters2003-03-231-1/+1
| | | | | | | | | | | Arranged that all the objects exposed by __builtin__ appear in the list of all objects. I basically peed away two days tracking down a mystery leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because the object leaking the references didn't appear in the sys.getobjects(0) list. The object happened to be False. Now False is in the list, along with other popular & previously missing leak candidates (like None). Alas, we still don't have a choke point covering *all* Python objects, so the list of all objects may still be incomplete.
* Refactored some of the Py_TRACE_REFS code. New private API functionTim Peters2003-03-231-0/+1
| | | | | | | _Py_AddToAllObjects() that simply inserts an object at the front of the doubly-linked list of all objects. Changed PyType_Ready() (the closest thing we've got to a choke point for type objects) to call that.
* New private API functions _PyFloat_{Pack,Unpack}(4,8}. This is aTim Peters2003-03-201-0/+42
| | | | | refactoring to get all the duplicates of this delicate code out of the cPickle and struct modules.
* Fixed SF bug #663074. The codec system was using global staticGustavo Niemeyer2003-03-191-0/+4
| | | | | | | | | variables to store internal data. As a result, any atempts to use the unicode system with multiple active interpreters, or successive interpreter executions, would fail. Now that information is stored into members of the PyInterpreterState structure.
* Renamed PyObject_GenericGetIter to PyObject_SelfIterRaymond Hettinger2003-03-171-1/+1
| | | | | | to more accurately describe what the function does. Suggested by Thomas Wouters.
* Created PyObject_GenericGetIter().Raymond Hettinger2003-03-171-0/+1
| | | | Factors out the common case of returning self.
* - The extended type structure used for heap types (new-styleGuido van Rossum2003-03-071-0/+22
| | | | | classes defined by Python code using a class statement) is now exported from object.h as PyHeapTypeObject. (SF patch #696193.)
* Fix SF bug #697256, PyMarshal_WriteShortToFile() documented, but not implementedNeal Norwitz2003-03-061-1/+0
| | | | Remove prototype and doc. Backport candidate.
* Moved the Apple workaround for the guard define for wchar_t out ofJack Jansen2003-02-281-1/+2
| | | | | the #ifdef HAVE_NCURSES_H: the same problem exists on OSX 10.1 with a fink-installed curses (which uses curses.h as the include file name).
* Fix spelling and grammar.Raymond Hettinger2003-02-281-5/+5

* Update PY_VERSION to indicate that we're beyond 2.3a2 now.Guido van Rossum2003-02-201-1/+1
|
* As far as I can tell PyEval_GetOwner was removed in 1997 (when it wasMichael W. Hudson2003-02-201-1/+0
| | | | | called something else!). I can't imagine removing the prototype is going to hurt, but put it back if *you* can.
* - PyEval_GetFrame() is now declared to return a PyFrameObject *Guido van Rossum2003-02-192-2/+6
| | | | instead of a plain PyObject *. (SF patch #686601 by Ben Laurie.)
* Bump version # to 2.3a2.Tim Peters2003-02-181-2/+2
|
* - Finally fixed the bug in compile() and exec where a string endingGuido van Rossum2003-02-132-0/+3
| | | | | | | | | with an indented code block but no newline would raise SyntaxError. This would have been a four-line change in parsetok.c... Except codeop.py depends on this behavior, so a compilation flag had to be invented that causes the tokenizer to revert to the old behavior; this required extra changes to 2 .h files, 2 .c files, and 2 .py files. (Fixes SF bug #501622.)
* Make comments agree with code (I think).Michael W. Hudson2003-02-101-3/+4

* patch #683515: "Add unicode support to compile(), eval() and exec"Just van Rossum2003-02-101-0/+1
| | | | Incorporated nnorwitz's comment re. Py__USING_UNICODE.
* Small function call optimization and special build option for call stats.Jeremy Hylton2003-02-052-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | -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.
* Provide __module__ attributes for functions defined in C and Python.Jeremy Hylton2003-01-312-1/+8
| | | | | | | | | | | | | | __module__ is the string name of the module the function was defined in, just like __module__ of classes. In some cases, particularly for C functions, the __module__ may be None. Change PyCFunction_New() from a function to a macro, but keep an unused copy of the function around so that we don't change the binary API. Change pickle's save_global() to use whichmodule() if __module__ is None, but add the __module__ logic to whichmodule() since it might be used outside of pickle.
* _PyLong_NumBits(): The definition of this was too specific to the quirkyTim Peters2003-01-311-5/+11
| | | | | | | | | needs of pickling longs. Backed off to a definition that's much easier to understand. The pickler will have to work a little harder, but other uses are more likely to be correct <0.5 wink>. _PyLong_Sign(): New teensy function to characterize a long, as to <0, ==0, or >0.
* Added new private API function _PyLong_NumBits. This will be used at theTim Peters2003-01-281-0/+11
| | | | | | | start for the C implemention of new pickle LONG1 and LONG4 opcodes (the linear-time way to pickle a long is to call _PyLong_AsByteArray, but the caller has no idea how big an array to allocate, and correct calculation is a bit subtle).
* SF bug #670229: doc improvement for cStringIO.hRaymond Hettinger2003-01-191-5/+12
| | | | Gernot Hillier added more detail to the internal API documentation.
* It turns out that some calls return AEDesc records that are "borrowed",Jack Jansen2003-01-171-0/+1
| | | | | | | the AEDesc data shouldn't be disposed when the Python object is. Added a C call AEDesc_NewBorrowed() to create these objects and a Python method old=AEDesc.AutoDispose(onoff) to change auto-dispose state.

* Minor fiddling to make the next part easier. Introduced an internalTim Peters2003-01-111-21/+41

* Got rid of the timetz type entirely. This was a bit trickier than ITim Peters2003-01-101-12/+17
| | | | | | | hoped it would be, but not too bad. A test had to change: time.__setstate__() can no longer add a non-None tzinfo member to a time object that didn't already have one, since storage for a tzinfo member doesn't exist in that case.
* Patch #661760: Cygwin auto-import module patchJason Tishler2003-01-061-1/+5
| | | | | | | | | | | | The attached patch enables shared extension modules to build cleanly under Cygwin without moving the static initialization of certain function pointers (i.e., ones exported from the Python DLL core) to a module initialization function. Additionally, this patch fixes the modules that have been changed in the past to accommodate Cygwin.
* Move _PyInt_Init() into pythonrun.h, since all the other _Init()Neal Norwitz2003-01-012-1/+1

* SF #561244, Micro optimizationsNeal Norwitz2002-12-302-0/+2
| | | | | | Initialize the small integers and __builtins__ in startup. This removes some if conditions. Change XDECREF to DECREF for values which shouldn't be NULL.
* PEP 302 + zipimport:Just van Rossum2002-12-301-0/+1
| | | | | | | | | | | | | - new import hooks in import.c, exposed in the sys module - new module called 'zipimport' - various changes to allow bootstrapping from zip files I hope I didn't break the Windows build (or anything else for that matter), but then again, it's been sitting on sf long enough... Regarding the latest discussions on python-dev: zipimport sets pkg.__path__ as specified in PEP 273, and likewise, sys.path item such as /path/to/Archive.zip/subdir/ are supported again.
* Apparently FreeBSD enables some HW floating-point exceptions by default.Tim Peters2002-12-281-5/+10
| | | | | | | This can cause core dumps when Python runs. Python relies on the 754- (and C99-) mandated default "non-stop" mode for FP exceptions. This patch from Ben Laurie disables at least one FP exception on FreeBSD at Python startup time.

* Provide mechanism to deprecate functions, types, and struct members.Neal Norwitz2002-12-191-0/+13
| | | | It would be nice to support other compilers besides gcc.
