* This closes patch:Michael W. Hudson2004-07-071-1/+1
| | | | | | | | | | | | | | | | | [ 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.
* SF Bug #215126: Over restricted type checking on eval() functionRaymond Hettinger2004-07-021-4/+16
| | | | | | 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.
* Patch #966493: Cleanup generator/eval_frame exposure.Martin v. Löwis2004-06-271-14/+6

* Get ceval.c to compile again by moving declarations before other statments.Raymond Hettinger2004-06-261-1/+2

* Install two code generation optimizations that depend on NOP.Raymond Hettinger2004-06-211-0/+3
| | | | Reduces the cost of "not" to almost zero.
* Performance tweak: allow stack_pointer and oparg to be register variables.Armin Rigo2004-06-171-7/+16
| | | | SF patch #943898
* Patch #510695: Add TSC profiling for the VM.Martin v. Löwis2004-06-081-2/+150
|
* SF bug #963956: Bad error mesage when subclassing a moduleRaymond Hettinger2004-06-051-0/+9
| | | | | | 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).
* Patch #957398: Add public API for Generator Object/Type.Martin v. Löwis2004-06-011-138/+8

* Some (but not all) of the why code bitfield tests ran faster asRaymond Hettinger2004-04-111-3/+4
| | | | separate equality tests. Now, all are set to their best timing.
* Revert 2.393, elimination of pre-decrementing, whichRaymond Hettinger2004-04-101-17/+13
| | | | did not stand-up to additional timings.
* Use continue instead of break whereever possible.Raymond Hettinger2004-04-071-2/+8
|
* * Improve readability and remove data dependencies by convertingRaymond Hettinger2004-04-071-14/+18
| | | | | | | | 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.
* Small code improvements for readability, code size, and/or speed.Raymond Hettinger2004-04-071-58/+54
| | | | | | | | | | | | | | | | | | | | | | | 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
* Simplify previous checkin (bitfields for WHY codes).Raymond Hettinger2004-04-061-12/+14
| | | | Restores the self-documenting enum declaration.
* Coded WHY flags as bitfields (taking inspiration from tp_flags).Raymond Hettinger2004-04-061-20/+16
| | | | | This allows multiple flags to be tested in a single compare which eliminates unnecessary compares and saves a few bytes.
* Since the fast_yield branch target was introduced, it appears that mostTim Peters2004-04-051-41/+41
| | | | | | | 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).

* Cancelled checkin, sorry.Armin Rigo2004-03-201-10/+6

* A 2% speed improvement with gcc on low-endian machines. My guess is that thisArmin Rigo2004-03-201-6/+10
| | | | | new pattern for NEXTARG() is detected and optimized as a single (*short) loading.
* LIST_APPEND is predicably followed by JUMP_ABSOLUTE.Raymond Hettinger2004-03-121-1/+5
| | | | Reduces loop overhead by an additional 10%.
* Move the code for BREAK and CONTINUE_LOOP to be near FOR_ITER.Raymond Hettinger2004-03-121-9/+9
| | | | | Makes it more likely that all loop operations are in the cache at the same time.
* Speedup for-loops by inlining PyIter_Next(). Saves duplicate testsRaymond Hettinger2004-03-121-8/+10
| | | | | and a function call resulting in a 15% reduction of total loop overhead (as measured by timeit.Timer('pass')).
* Refactor and optimize code for UNPACK_SEQUENCE.Raymond Hettinger2004-03-081-27/+13
| | | | | | | | | | * 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.
* SF patch #910929: Optimize list comprehensionsRaymond Hettinger2004-03-071-0/+9
| | | | | Add a new opcode, LIST_APPEND, and apply it to the code generation for list comprehensions. Reduces the per-loop overhead by about a third.
* Add pystack definition to Misc/gdbinit with some explanation of its behaviorSkip Montanaro2004-03-011-0/+4
| | | | | and add flag comments to ceval.c and main.c alerting people to the coupling between pystack and the layout of those files.
* This is my patch #876198 plus a NEWS entry and a header frob.Michael W. Hudson2004-02-121-1/+1
| | | | | Remove the ability to use (from C) arbitrary objects supporting the read buffer interface as the co_code member of code objects.
* remove support for missing ANSI C header files (limits.h, stddef.h, etc).Skip Montanaro2004-02-101-11/+0

* SF patch #884022: dynamic execution profiling vs opcode predictionRaymond Hettinger2004-02-081-0/+9
| | | | | | | | | (Contributed by Andrew I MacIntyre.) disables opcode prediction when dynamic execution profiling is in effect, so the profiling counters at the top of the main interpreter loop in eval_frame() are updated for each opcode.
* SF patch #864059: optimize eval_frameRaymond Hettinger2004-02-061-5/+6
| | | | | | Simplified version of Neal Norwitz's patch which adds gotos for opcodes that set "why". This skips a number of tests where the outcome of the tests are known in advance.
* Getting rid of all the code inside #ifdef macintosh too.Jack Jansen2003-11-201-5/+1

| | | | | SF patch 825639 http://mail.python.org/pipermail/python-dev/2003-October/039445.html
* oh dear. Wrong manipulation. Committed a version of ceval.c from myArmin Rigo2003-10-251-28/+20
| | | | | | no-cyclic-comparison patch at the same time as errors.c. Reverting ceval.c to the previous revision.
* Made function declaration a proper C prototypeArmin Rigo2003-10-251-20/+28
|
* Simplify and speedup uses of Py_BuildValue():Raymond Hettinger2003-10-121-3/+3
| | | | | | * Py_BuildValue("(OOO)",a,b,c) --> PyTuple_Pack(3,a,b,c) * Py_BuildValue("()",a) --> PyTuple_New(0) * Py_BuildValue("O", a) --> Py_INCREF(a)
* Fix SF #762455, segfault when sys.stdout is changed in getattrNeal Norwitz2003-06-291-0/+6
| | | | Will backport.
* Add PyThreadState_SetAsyncExc(long, PyObject *).Guido van Rossum2003-06-281-1/+17
| | | | | | | | | A new API (only accessible from C) to interrupt a thread by sending it an exception. This is not always effective, but might help some people. Requested by Just van Rossum and Alex Martelli. It is intentional that you have to write your own C extension to call it from Python. Docs will have to wait.
* Use fast_next_opcode shortcut for forward jump opcodes (it's safe andNeil Schemenauer2003-06-011-5/+5
| | | | gives a small speedup).
* SF bug #733667: kwargs handled incorrectlyRaymond Hettinger2003-05-311-1/+1
| | | | | The fast_function() inlining optimization only applies when there are zero keyword arguments.
* Don't use fast_next_opcode for JUMP_* opcodes. This fixes the problemNeil Schemenauer2003-05-301-6/+6
| | | | reported by Kurt B. Kaiser.
* Armin Rigo's fix & test forMichael W. Hudson2003-04-291-9/+10
| | | | | | [ 729622 ] line tracing hook errors with massaging from me to integrate test into test suite.
* Revert the previous enhancement to the bytecode optimizer.Raymond Hettinger2003-04-241-3/+0
| | | | The additional code complexity and new NOP opcode were not worth it.
