Georg Brandl 7e3ba2a699 Bug #1535165: fixed a segfault in input() and raw_input() when
sys.stdin is closed.

Martin Blais 215f13dd11 Normalized a few cases of whitespace in function declarations.
Found them using::

  find . -name '*.py' | while read i ; do grep 'def[^(]*( ' $i /dev/null ; done
  find . -name '*.py' | while read i ; do grep ' ):' $i /dev/null ; done

(I was doing this all over my own code anyway, because I'd been using spaces in
all defs, so I thought I'd make a run on the Python code as well.  If you need
to do such fixes in your own code, you can use xx-rename or parenregu.el within
emacs.)

Tim Peters 696cf43b58 Heavily fiddled variant of patch #1442927: PyLong_FromString optimization.
``long(str, base)`` is now up to 6x faster for non-power-of-2 bases.  The
largest speedup is for inputs with about 1000 decimal digits.  Conversion
from non-power-of-2 bases remains quadratic-time in the number of input
digits (it was and remains linear-time for bases 2, 4, 8, 16 and 32).

Speedups at various lengths for decimal inputs, comparing 2.4.3 with
current trunk.  Note that it's actually a bit slower for 1-digit strings:

Tim Peters b713ec2531 Bug #1334662 / patch #1335972: int(string, base) wrong answers.
In rare cases of strings specifying true values near sys.maxint,
and oddball bases (not decimal or a power of 2), int(string, base)
could deliver insane answers.  This repairs all such problems, and
also speeds string->int significantly.  On my box, here are %
speedups for decimal strings of various lengths:

length speedup
------ -------
 1       12.4%
 2       15.7%
 3       20.6%
 4       28.1%
 5       33.2%
 6       37.5%
 7       41.9%
 8       46.3%
 9       51.2%
10       19.5%
11       19.9%
12       23.9%
13       23.7%
14       23.3%
15       24.9%
16       25.3%
17       28.3%
18       27.9%
19       35.7%

Note that the difference between 9 and 10 is the difference between
short and long Python ints on a 32-bit box.  The patch doesn't
actually do anything to speed conversion to long:  the speedup is
due to detecting "unsigned long" overflow more quickly.

This is a bugfix candidate, but it's a non-trivial patch and it
would be painful to separate the "bug fix" from the "speed up" parts.

Brett Cannon c3647ac93e Make subclasses of int, long, complex, float, and unicode perform type
conversion using the proper magic slot (e.g., __int__()).  Also move conversion
code out of PyNumber_*() functions in the C API into the nb_* function.

Raymond Hettinger aa241e0149 Checkin Tim's fix to an error discussed on python-dev.
Also, add a testcase.

Formerly, the list_extend() code used several local variables to remember
its state across iterations.  Since an iteration could call arbitrary
Python code, it was possible for the list state to be changed.  The new
code uses dynamic structure references instead of C locals.  So, they
are always up-to-date.

After list_resize() is called, its size has been updated but the new
cells are filled with NULLs.  These needed to be filled before arbitrary
iteration code was called; otherwise, that code could attempt to modify
a list that was in a semi-invalid state.  The solution was to change
the ob->size field back to a value reflecting the actual number of valid
cells.

Jeremy Hylton 4c989ddc9c Subclasses of string can no longer be interned. The semantics of
interning were not clear here -- a subclass could be mutable, for
example -- and had bugs.  Explicitly interning a subclass of string
via intern() will raise a TypeError.  Internal operations that attempt
to intern a string subclass will have no effect.

Added a few tests to test_builtin that includes the old buggy code and
verifies that calls like PyObject_SetAttr() don't fail.  Perhaps these
tests should have gone in test_string.

Raymond Hettinger 214b1c3aae SF Bug #215126: Over restricted type checking on eval() function
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.

Guido van Rossum 6c9e130524 - Removed FutureWarnings related to hex/oct literals and conversions
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.

Raymond Hettinger a690a9967e * Migrate set() and frozenset() from the sandbox.

Guido van Rossum efbbb1c602 Patch by Chad Netzer (with significant change):
- range() now works even if the arguments are longs with magnitude
  larger than sys.maxint, as long as the total length of the sequence
  fits.  E.g., range(2**100, 2**101, 2**100) is the following list:
  [1267650600228229401496703205376L].  (SF patch #707427.)

Walter Dörwald 8dd19321bb Change filtertuple() to use tp_as_sequence->sq_item
instead of PyTuple_GetItem, so an overwritten __getitem__
in a tuple subclass works. SF bug #665835.
2003-02-10 17:36:40 +00:00
Walter Dörwald 1918f7755e Change filterstring() and filterunicode(): If the
object is not a real str or unicode but an instance
of a subclass, construct the output via looping
over __getitem__. This guarantees that the result
is the same for function==None and function==lambda x:x

This doesn't happen for tuples, because filtertuple()
uses PyTuple_GetItem().

(This was discussed on SF bug #665835).

Walter Dörwald c3da83fcd7 Make sure filter() never returns tuple, str or unicode

2003-02-04 20:24:45 +00:00
Walter Dörwald 5e61e24d55 Add a test that checks that filter() honors the sq_item slot for
str and unicode subclasses not just for generating the output
but for testing too.
2003-02-04 17:04:01 +00:00
Walter Dörwald 903f1e0c40 filterstring() and filterunicode() in Python/bltinmodule.c
blindly assumed that tp_as_sequence->sq_item always returns
a str or unicode object. This might fail with str or unicode
subclasses.

This patch checks whether the object returned from __getitem__
is a str/unicode object and raises a TypeError if not (and
the filter function returned true).

Furthermore the result for __getitem__ can be more than one
character long, so checks for enough memory have to be done.
