Neal Norwitz	5f5153e871	Fix some mods that got dropped from the AST merge	21 years ago
Jeremy Hylton	3e0055f8c6	Merge ast-branch to head This change implements a new bytecode compiler, based on a transformation of the parse tree to an abstract syntax defined in Parser/Python.asdl. The compiler implementation is not complete, but it is in stable enough shape to run the entire test suite excepting two disabled tests.	21 years ago
Armin Rigo	1c2d7e5363	clean-up tracing of C functions. In particular, don't call the trace func with an exception currently set!	21 years ago
Barry Warsaw	e2eca0b709	Port from the Python 2.4 branch, patches for SF bug # 900092, hotshot.stats.load.	21 years ago
Phillip J. Eby	0d6615fd29	PEP 342 implementation. Per Guido's comments, the generator throw() method still needs to support string exceptions, and allow None for the third argument. Documentation updates are needed, too.	21 years ago
Brett Cannon	c9371d4a1b	Fix signedness of various char variables to stop causing a warning under gcc 4.	21 years ago
Brett Cannon	55fa66dd45	Add comments about PyThreadState and the usage of its fields.	21 years ago
Hye-Shik Chang	b6fa2814f7	Make a handy macro, Py_DEFAULT_RECURSION_LIMIT to allow to define a default value of recursion limit from build systems. 1000 levels are still too high for some 64bit systems.	21 years ago
Michael W. Hudson	75eabd2944	Change the name of the macro used by --with-tsc builds to the less inscrutable READ_TIMESTAMP.	21 years ago
Skip Montanaro	c9a4762bd6	comment tweak	21 years ago
Kurt B. Kaiser	4c79a83e0c	Hye-Shik Chang's fix for Bug 875692. Improve signal handling, especially when using threads, by forcing an early re-execution of PyEval_EvalFrame() "periodic" code when things_to_do is not cleared by Py_MakePendingCalls(). M Misc/NEWS M Python/ceval.c	22 years ago
Tim Peters	7f468f29f4	SF patch 1044089: New C API function PyEval_ThreadsInitialized(), by Nick Coghlan, for determining whether PyEval_InitThreads() has been called. Also purged the undocumented+unused _PyThread_Started int.	22 years ago
Raymond Hettinger	cfc3192677	SF bug #1014215 : Unspecific errors with metaclass High level error message was stomping useful detailed messages from lower level routines. The new approach is to augment string error messages returned by the low level routines. The provides both high and low level information. If the exception value is not a string, no changes are made. To see the improved messages in action, type: import random class R(random): pass class B(bool): pass	22 years ago
Martin v. Löwis	87fa785f0f	Centralize WITH_TSC processing.	22 years ago
Michael W. Hudson	800ba2375a	This is my patch: [ 1005891 ] support --with-tsc on PPC plus a trivial change to settscdump's docstring and a Misc/NEWS entry.	22 years ago
Armin Rigo	618fbf5469	This was quite a dark bug in my recent in-place string concatenation hack: it would resize interned strings in-place! This occurred because their reference counts do not have their expected value -- stringobject.c hacks them. Mea culpa.	22 years ago
Raymond Hettinger	52a21b8e65	SF patch #980695 : efficient string concatenation (Original patch by Armin Rigo).	22 years ago
Michael W. Hudson	a3711f73c1	Fix for the unfortunate fact that PyDict_GetItem and PyObject_GetItem have differing refcount semantics. If anyone sees a prettier way to acheive the same ends, then please go for it. I think this is the first time I've ever used Py_XINCREF.	22 years ago
Raymond Hettinger	66bd233225	Completed the patch for Bug #215126 . * Fixes an incorrect variable in a PyDict_CheckExact. * Allow general mapping locals arguments for the execfile() function and exec statement. * Add tests.	22 years ago
Neal Norwitz	93468eac72	Remove unused macros in .c files	22 years ago
Michael W. Hudson	30ea2f223f	This closes patch: [ 960406 ] unblock signals in threads although the changes do not correspond exactly to any patch attached to that report. Non-main threads no longer have all signals masked. A different interface to readline is used. The handling of signals inside calls to PyOS_Readline is now rather different. These changes are all a bit scary! Review and cross-platform testing much appreciated.	22 years ago
Raymond Hettinger	214b1c3aae	SF Bug #215126 : Over restricted type checking on eval() function The builtin eval() function now accepts any mapping for the locals argument. Time sensitive steps guarded by PyDict_CheckExact() to keep from slowing down the normal case. My timings so no measurable impact.	22 years ago
Martin v. Löwis	8d97e33bb7	Patch #966493 : Cleanup generator/eval_frame exposure.	22 years ago
Raymond Hettinger	a7f56bc0cc	Get ceval.c to compile again by moving declarations before other statments.	22 years ago
Nicholas Bastin	d858a7763a	Massive performance improvement for C extension and builtin tracing code	22 years ago
Nicholas Bastin	941b8bc41a	Less ugly #ifdefs for C profiling fix	22 years ago
Nicholas Bastin	bbffbd1983	One forgotten C profiling #ifdef	22 years ago
Nicholas Bastin	4c70b69fb1	Making C profiling a configure option (at least temporarily)	22 years ago
Raymond Hettinger	9c18e81fb2	Install two code generation optimizations that depend on NOP. Reduces the cost of "not" to almost zero.	22 years ago
Armin Rigo	8817fcdba5	Performance tweak: allow stack_pointer and oparg to be register variables. SF patch #943898	22 years ago
Martin v. Löwis	f30d60edbc	Patch #510695 : Add TSC profiling for the VM.	22 years ago
Raymond Hettinger	f2c0830585	SF bug #963956 : Bad error mesage when subclassing a module Add a more informative message for the common user mistake of subclassing from a module name rather than another class (i.e. random instead of random.random).	22 years ago
Martin v. Löwis	e440e47e91	Patch #957398 : Add public API for Generator Object/Type.	22 years ago
Raymond Hettinger	c8aa08b172	Some (but not all) of the why code bitfield tests ran faster as separate equality tests. Now, all are set to their best timing.	22 years ago
Raymond Hettinger	5bed456056	Revert 2.393, elimination of pre-decrementing, which did not stand-up to additional timings.	22 years ago
Raymond Hettinger	7eddd78a15	Use continue instead of break whereever possible.	22 years ago
Raymond Hettinger	d3b836d202	* Improve readability and remove data dependencies by converting pre-increment forms to post-increment forms. Post-incrementing also eliminates the need for negative array indices for oparg fetches. * In exception handling code, check for class based exceptions before the older string based exceptions.	22 years ago
Raymond Hettinger	467a698bd2	Small code improvements for readability, code size, and/or speed. BINARY_SUBSCR: * invert test for normal case fall through * eliminate err handling code by jumping to slow_case LOAD_LOCALS: * invert test for normal case fall through * continue instead of break for the non-error case STORE_NAME and DELETE_NAME: * invert test for normal case fall through LOAD_NAME: * continue instead of break for the non-error case DELETE_FAST: * invert test for normal case fall through LOAD_DEREF: * invert test for normal case fall through * continue instead of break for the non-error case	22 years ago
Raymond Hettinger	7c9586545e	Simplify previous checkin (bitfields for WHY codes). Restores the self-documenting enum declaration.	22 years ago
Raymond Hettinger	06032cb664	Coded WHY flags as bitfields (taking inspiration from tp_flags). This allows multiple flags to be tested in a single compare which eliminates unnecessary compares and saves a few bytes.	22 years ago
Tim Peters	8a5c3c76be	Since the fast_yield branch target was introduced, it appears that most tests of "why" against WHY_YIELD became useless. This patch removes them, but assert()s that why != WHY_YIELD everywhere such a test was removed. The test suite ran fine under a debug build (i.e., the asserts never triggered).	22 years ago
Nicholas Bastin	e5662aedef	Changed random calls to PyThreadState_Get() to use the macro	22 years ago
Nicholas Bastin	c69ebe8d50	Enable the profiling of C functions (builtins and extensions)	22 years ago
Armin Rigo	bf57a14522	Fix SF bug #765624 .	22 years ago
Armin Rigo	9dbf9084e8	Cancelled checkin, sorry.	22 years ago
Armin Rigo	1515fc2a01	A 2% speed improvement with gcc on low-endian machines. My guess is that this new pattern for NEXTARG() is detected and optimized as a single (*short) loading.	22 years ago
Raymond Hettinger	fba1cfc49a	LIST_APPEND is predicably followed by JUMP_ABSOLUTE. Reduces loop overhead by an additional 10%.	22 years ago
Raymond Hettinger	2d783e9b16	Move the code for BREAK and CONTINUE_LOOP to be near FOR_ITER. Makes it more likely that all loop operations are in the cache at the same time.	22 years ago
Raymond Hettinger	db0de9e7ca	Speedup for-loops by inlining PyIter_Next(). Saves duplicate tests and a function call resulting in a 15% reduction of total loop overhead (as measured by timeit.Timer('pass')).	22 years ago
Raymond Hettinger	f114a3ae63	Refactor and optimize code for UNPACK_SEQUENCE. * Defer error handling for wrong number of arguments to the unpack_iterable() function. Cuts the code size almost in half. * Replace function calls to PyList_Size() and PyTuple_Size() with their smaller and faster macro counterparts. * Move the constant structure references outside of the inner loops.	22 years ago
