Jack Jansen c32cec14b4 Don't use "dict" as a variable, it shadows the builtin. Spotted by
Bob Ippolito.
2004-03-13 23:32:47 +00:00
Skip Montanaro 6e098a15a3 compile.h and eval.h weren't being included which kept a fair bit of the
public API from being exposed by simply including Python.h (as recommended).

Jack Jansen 0576d0a48a Force option should be applied to a single package, not recursively
to its dependencies. Fixes #733819.

Raymond Hettinger 3aa82c07f7 SF bug #910986: copy.copy fails for array.array
Added support for the copy module.

Raymond Hettinger 42bec93e5c Make PySequence_Fast_ITEMS public. (Thanks Skip.) 2004-03-12 16:38:17 +00:00
Raymond Hettinger fba1cfc49a LIST_APPEND is predicably followed by JUMP_ABSOLUTE.
Reduces loop overhead by an additional 10%.

Raymond Hettinger 6e058d70ef * Eliminate duplicate call to PyObject_Size().
(Spotted by Michael Hudson.)

* Now that "selflen" is no longer inside a loop, it should not be a
  register variable.

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.

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')).
2004-03-12 08:41:36 +00:00
Raymond Hettinger c1e4f9dd92 Use a new macro, PySequence_Fast_ITEMS to factor out code common to
three recent optimizations.  Aside from reducing code volume, it
increases readability.

Jack Jansen 989ddc0709 - Added a downloader using urllib2 in stead of curl, based on code
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.

Raymond Hettinger 57c4542bcd Now that list.extend() is at the root of many list operations, it becomes
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).
2004-03-11 09:48:18 +00:00
Raymond Hettinger 8ca92ae54c Eliminate a big block of duplicate code in PySequence_List() by
exposing _PyList_Extend().
2004-03-11 09:13:12 +00:00
Raymond Hettinger 97bc618229 list_inplace_concat() is now expressed in terms of list_extend() which
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.

Raymond Hettinger 66d31f8f38 Use memcpy() instead of memmove() when the buffers are known to be distinct. 2004-03-10 11:44:04 +00:00
Raymond Hettinger ef9bf4031a Tidied up the implementations of reversed (including the custom ones
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.
2004-03-10 10:10:42 +00:00
Raymond Hettinger d2c36261a2 Eliminate the double reverse option. It's only use case
was academic and it was potentially confusing to use.

Raymond Hettinger a6366fe085 Optimize inner loops for subscript, repeat, and concat. 2004-03-09 13:05:22 +00:00
Raymond Hettinger f889e10c19 Optimize slice assignments.
* 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.

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.

Brett Cannon 4b6b7f1515 Remove calls to currentThread() in _Condition methods that were side-effect.
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 .
2004-03-08 22:18:57 +00:00
Raymond Hettinger 3fd500b4a5 The copy module now handles sets directly. The __copy__ methods are no
longer needed.

Raymond Hettinger 3e47f65e28 SF patch #907403: Improvements to cStringIO.writelines()
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.

Raymond Hettinger b7d05db0be Optimize tuple_slice() and make further improvements to list_slice()
and list.extend().  Factoring the inner loops to remove the constant
structure references and fixed offsets gives speedups ranging from
20% to 30%.

Raymond Hettinger f0e3569a28 Refactor the copy dispatcher code in copy.py. Simplifies and shortens
the code by grouping common cases together.
2004-03-08 05:59:33 +00:00
Raymond Hettinger 99842b6534 Small optimizations for list_slice() and list_extend_internal().
* 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.

Brett Cannon 8172ac3d15 Deal with possible case of having time.tzname[1] containing UTC or GMT.
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] .

Raymond Hettinger 31017aed36 SF #904720: dict.update should take a 2-tuple sequence like dict.__init_
(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.

Brett Cannon d1080a3418 Have strftime() check its time tuple argument to make sure the tuple's values
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.

Raymond Hettinger 0a4977c2f3 Replace left(), right(), and __reversed__() with the more general purpose
__getitem__() and __setitem__().

Simplifies the API, reduces the code size, adds flexibility, and makes
deques work with bisect.bisect(), random.shuffle(), and random.sample().
