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  out-of-date and did not reflect that iterable arguments were allowed.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 .

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.

Raymond Hettinger ebedb2f773 Factor out code common to PyDict_Copy() and PyDict_Merge(). 2004-03-08 04:19:01 +00:00
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] .
Fixes bug #897817 .

Raymond Hettinger dd80f76265 SF patch #910929: Optimize list comprehensions
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.

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().

Neal Norwitz 9a8d55e4a1 Cleanup: remove test file after it is used. 2004-02-29 15:37:50 +00:00
Raymond Hettinger 738ec90ca1 Improvements to collections.deque():
* Add doctests for the examples in the library reference.
* Add two methods, left() and right(), modeled after deques in C++ STL.
* Apply the new method to asynchat.py.
* Add comparison operators to make deques more substitutable for lists.
* Replace the LookupErrors with IndexErrors to more closely match lists.

Jack Jansen afd63b9c40 Started on version 0.4: better scheme for finding correct database:
- Try not only "darwin-7.X.Y" but also "darwin-7.X" and "darwin-7",
  so far we've never had to create anew database for a minor release.
- Distinguish between the various different installs (user-installed
  MacPython, apple-installed MacPython, other).

Gregory P. Smith a7befda8d8 Fixes SF bug # 778421
* Fixed a bug in the compatibility interface set_location() method
   where it would not properly search to the next nearest key when
   used on BTree databases.  [SF bug id 788421]
 * Fixed a bug in the compatibility interface set_location() method
   where it could crash when looking up keys in a hash or recno
   format database due to an incorrect free().

Jeremy Hylton b3ee6f9921 Fix two bugs in the new do_open() implementation for HTTPHandler.
Invoke the standard error handlers for non-200 responses.

Always supply a "Connection: close" header to prevent the server from
leaving the connection open.  Downstream users of the socket may
attempt recv()/read() with no arguments, which would block if the
connection were kept open.
