* SF bug #910986: copy.copy fails for array.arrayRaymond Hettinger2004-03-133-0/+24
| | | | Added support for the copy module.
* Make PySequence_Fast_ITEMS public. (Thanks Skip.)Raymond Hettinger2004-03-122-4/+4

* LIST_APPEND is predicably followed by JUMP_ABSOLUTE.Raymond Hettinger2004-03-121-1/+5
| | | | Reduces loop overhead by an additional 10%.
* * Eliminate duplicate call to PyObject_Size().Raymond Hettinger2004-03-121-3/+3
| | | | | | | (Spotted by Michael Hudson.) * Now that "selflen" is no longer inside a loop, it should not be a register variable.
* 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')).
* Use a new macro, PySequence_Fast_ITEMS to factor out code common toRaymond Hettinger2004-03-124-16/+19
| | | | | three recent optimizations. Aside from reducing code volume, it increases readability.
* - Added a downloader using urllib2 in stead of curl, based on codeJack Jansen2004-03-111-51/+137
| | | | | | | donated by Kevin Ollivier. This is now the default downloader. - Added a watcher mechanism, whereby downloaders and unpackers (and, later builders) can give status feedback to the user. When running pimp as a command line tool in verbose mode print this output.
* Now that list.extend() is at the root of many list operations, it becomesRaymond Hettinger2004-03-111-3/+9
| | | | | | | worth it to in-line the call to PyIter_Next(). Saves another 15% on most list operations that acceptable a general iterable argument (such as the list constructor).
* Eliminate a big block of duplicate code in PySequence_List() byRaymond Hettinger2004-03-113-54/+13
| | | | exposing _PyList_Extend().
* list_inplace_concat() is now expressed in terms of list_extend() whichRaymond Hettinger2004-03-111-14/+13
| | | | | | | | avoids creating an intermediate tuple for iterable arguments other than lists or tuples. In other words, a+=b no longer requires extra memory when b is not a list or tuple. The list and tuple cases are unchanged.
* Make buffer objects based on mutable objects (like array) safe.Neil Schemenauer2004-03-112-82/+154

* Document one of the many problems with the buffer object.Neil Schemenauer2004-03-111-2/+9
|
* Rename static functions, they should not have the _Py prefix.Neil Schemenauer2004-03-111-11/+10
|
* Make test_coercion.py less sensitive to platform fp quirks. ClosesNeil Schemenauer2004-03-102-333/+348
| | | | SF bug #678265.
* Use memcpy() instead of memmove() when the buffers are known to be distinct.Raymond Hettinger2004-03-101-2/+2
|
* Tidied up the implementations of reversed (including the custom onesRaymond Hettinger2004-03-104-28/+58
| | | | | | | | | | | | | | | | | for xrange and list objects). * list.__reversed__ now checks the length of the sequence object before calling PyList_GET_ITEM() because the mutable could have changed length. * all three implementations are now tranparent with respect to length and maintain the invariant len(it) == len(list(it)) even when the underlying sequence mutates. * __builtin__.reversed() now frees the underlying sequence as soon as the iterator is exhausted. * the code paths were rearranged so that the most common paths do not require a jump.
* Eliminate the double reverse option. It's only use caseRaymond Hettinger2004-03-102-17/+2
| | | | was academic and it was potentially confusing to use.
* Optimize inner loops for subscript, repeat, and concat.Raymond Hettinger2004-03-092-36/+59
|
* Optimize slice assignments.Raymond Hettinger2004-03-091-16/+17
| | | | | | | | | | | | | * Replace sprintf message with a constant message string -- this error message ran on every invocation except straight deletions but it was only needed when the rhs was not iterable. The message was also out-of-date and did not reflect that iterable arguments were allowed. * For inner loops that do not make ref count adjustments, use memmove() for fast copying and better readability. * For inner loops that do make ref count adjustments, speed them up by factoring out the constant structure reference and using vitem[] instead.
* SF Patch #912462: Relocate \end tag to the right place.Hye-Shik Chang2004-03-091-1/+2
| | | | (Submitted by George Yoshida)
* 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.
* Remove calls to currentThread() in _Condition methods that were side-effect.Brett Cannon2004-03-081-2/+0
| | | | | | | | | Side-effects were deemed unnecessary and were causing problems at shutdown time when threads were catching exceptions at start time and then triggering exceptions trying to call currentThread() after gc'ed. Masked the initial exception which was deemed bad. Fixes bug #754449 .
* The copy module now handles sets directly. The __copy__ methods are noRaymond Hettinger2004-03-081-4/+0
| | | | longer needed.
* SF patch #907403: Improvements to cStringIO.writelines()Raymond Hettinger2004-03-081-0/+5
| | | | | | | The writelines() method now accepts any iterable argument and writes the lines one at a time rather than using ''.join(lines) followed by a single write. Results in considerable memory savings and makes the method suitable for use with generator expressions.

* Optimize tuple_slice() and make further improvements to list_slice()Raymond Hettinger2004-03-083-18/+28
| | | | | | and list.extend(). Factoring the inner loops to remove the constant structure references and fixed offsets gives speedups ranging from 20% to 30%.
* Refactor the copy dispatcher code in copy.py. Simplifies and shortensRaymond Hettinger2004-03-081-35/+17
| | | | the code by grouping common cases together.
* Small optimizations for list_slice() and list_extend_internal().Raymond Hettinger2004-03-081-9/+20
| | | | | | | | * Using addition instead of substraction on array indices allows the compiler to use a fast addressing mode. Saves about 10%. * Using PyTuple_GET_ITEM and PyList_SET_ITEM is about 7% faster than PySequenceFast_GET_ITEM which has to make a list check on every pass.
* Factor out code common to PyDict_Copy() and PyDict_Merge().Raymond Hettinger2004-03-081-20/+6

* Deal with possible case of having time.tzname[1] containing UTC or GMT.Brett Cannon2004-03-071-2/+2
| | | | | | Since it is known ahead of time that UTC and GMT always have no DST adjustment then just set the isdst value to 0 even if tzname[0] == tzname[1] . Fixes bug #897817 .
* SF patch #910929: Optimize list comprehensionsRaymond Hettinger2004-03-076-3/+20
| | | | | 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.
* update version at top of fileSkip Montanaro2004-03-051-2/+2
|
* SF #904720: dict.update should take a 2-tuple sequence like dict.__init_Raymond Hettinger2004-03-0411-55/+91
| | | | | | | | (Championed by Bob Ippolito.) The update() method for mappings now accepts all the same argument forms as the dict() constructor. This includes item lists and/or keyword arguments.
* Special case endpoint access for speed.Raymond Hettinger2004-03-041-10/+18
|
* 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.
* * explain flags in doc stringsSkip Montanaro2004-03-033-15/+37
| | | | | * reverse order of files on the command line in pickle2db.py to make it symmetrical with db2pickle.py in the two-arg case (src, then dest)
* Fixed invalid syntax.Sjoerd Mullender2004-03-033-3/+3
|
* typoSkip Montanaro2004-03-031-1/+1
|
* Added license notices that are required to be included in theRaymond Hettinger2004-03-031-1/+331
| | | | documentation as well as the source code.
* Have strftime() check its time tuple argument to make sure the tuple's valuesBrett Cannon2004-03-026-4/+112
| | | | | | | | | | are within proper boundaries as specified in the docs. This can break possible code (datetime module needed changing, for instance) that uses 0 for values that need to be greater 1 or greater (month, day, and day of year). Fixes bug #897625.
* Replace left(), right(), and __reversed__() with the more general purposeRaymond Hettinger2004-03-014-148/+110
| | | | | | | __getitem__() and __setitem__(). Simplifies the API, reduces the code size, adds flexibility, and makes deques work with bisect.bisect(), random.shuffle(), and random.sample().
* Add pystack definition to Misc/gdbinit with some explanation of its behaviorSkip Montanaro2004-03-013-0/+30
| | | | | and add flag comments to ceval.c and main.c alerting people to the coupling between pystack and the layout of those files.
* Make deque_type static so namespace is not polluted.Neal Norwitz2004-02-291-2/+2
