* Decref all if ensure_fromlist fails. Fixes #876533.Martin v. Löwis2004-03-231-2/+3
| | | | Backported to 2.3.

* Improve byte coding for multiple assignments.Raymond Hettinger2004-03-211-3/+74
| | | | Gives 30% speedup on "a,b=1,2" and 25% on "a,b,c=1,2,3".
* 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 Hettinger2004-03-072-3/+10
| | | | | 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.
* SF Patch #902444: Use process scope thread on FreeBSD. System scopeHye-Shik Chang2004-03-041-1/+1
| | | | | is too expensive on FreeBSD's KSE threading infrastructure and even test_threadedimport fails on default setting.
* typoSkip Montanaro2004-03-031-1/+1
|
* 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 Montanaro2004-02-103-21/+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.
* Remove support for systems defining Py_PTHREAD_D[467] inSkip Montanaro2004-02-071-72/+0
| | | | Python/thread_pthread.h.
* 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.
* Fix input() builtin function to respect compiler flags.Hye-Shik Chang2004-02-021-1/+4
| | | | (SF patch 876178, patch by mwh, unittest by perky)
* Remove support for DYNIX, IRIX 4, --with-sgi-dl, --with-dl-dldSkip Montanaro2004-01-171-4/+0
|
* remove DGUX support.Skip Montanaro2004-01-172-14/+2

* Apply pre-sizing optimization to a broader class of objects.Raymond Hettinger2004-01-041-8/+4
| | | | | Formerly, the length was only fetched from sequence objects. Now, any object that reports its length can benefit from pre-sizing.
* Apply map/zip pre-sizing optimization to a broader class of objects.Raymond Hettinger2004-01-041-11/+7
| | | | | Formerly, the length was only fetched from sequence objects. Now, any object that reports its length can benefit from pre-sizing.

* Py_Finalize(): disabled the second call of cyclic gc, and added extensiveTim Peters2003-12-011-2/+27
| | | | | | | comments about why both calls to cyclic gc here can cause problems. I'll backport to 2.3 maint. Since the calls were introduced in 2.3, that will be the end of it.
* - Removed FutureWarnings related to hex/oct literals and conversionsGuido van Rossum2003-11-291-13/+1
| | | | | | | | | | and left shifts. (Thanks to Kalle Svensson for SF patch 849227.) This addresses most of the remaining semantic changes promised by PEP 237, except for repr() of a long, which still shows the trailing 'L'. The PEP appears to promise warnings for operations that changed semantics compared to Python 2.3, but this is not implemented; we've suffered through enough warnings related to hex/oct literals and I think it's best to be silent now.
