Martin v. Löwis 8d494f3241 Patch #1015021: Stop claiming that coerce can return None.
Will backport to 2.3.

Martin v. Löwis fd39ad4937 Patch #1005468: Disambiguate "min() or max()" exception string. 2004-08-12 14:42:37 +00:00
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.

Michael W. Hudson 52db519faa for some reason, the lack of adherence to Python's C whitespace rules
must have annoyed me at some point.

Raymond Hettinger 66bd233225 Completed the patch for Bug #215126.
* Fixes an incorrect variable in a PyDict_CheckExact.
* Allow general mapping locals arguments for the execfile() function
  and exec statement.
* Add tests.

Neil Schemenauer 3a313e3655 Check the type of values returned by __int__, __float__, __long__,
__oct__, and __hex__.  Raise TypeError if an invalid type is
returned.  Note that PyNumber_Int and PyNumber_Long can still
return ints or longs.  Fixes SF bug #966618.

Michael W. Hudson 30ea2f223f This closes patch:
[ 960406 ] unblock signals in threads

although the changes do not correspond exactly to any patch attached to
that report.

Non-main threads no longer have all signals masked.

A different interface to readline is used.

The handling of signals inside calls to PyOS_Readline is now rather
different.

These changes are all a bit scary!  Review and cross-platform testing
much appreciated.

Raymond Hettinger 513ffe8112 * Fix missing return after error message is set.
* Add a test case that would have caught it.

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.

Formerly, the length was only fetched from sequence objects.
Now, any object that reports its length can benefit from pre-sizing.

Guido van Rossum 28e83e3a66 Some errors from range() should be TypeError, not ValueError. 2003-04-15 12:43:26 +00:00
Guido van Rossum 817d6c9c9e Prompted by Tim's comment, when handle_range_longs() sees an
unexpected type, report the actual type rather than 'float'.  (It's
hard to even reach this code with a float. :-)
2003-04-14 18:25:04 +00:00
Tim Peters 874e1f7ed3 handle_range_longs(): refcount handling is very delicate here, and
the code erroneously decrefed the istep argument in an error case.  This
caused a co_consts tuple to lose a float constant prematurely, which
eventually caused gc to try executing static data in floatobject.c (don't
ask <wink>).  So reworked this extensively to ensure refcount correctness.
2003-04-13 22:13:08 +00:00
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.)

Raymond Hettinger ff41c48a77 SF patch #701494: more apply removals 2003-04-06 09:01:11 +00:00
Tim Peters 7571a0fbcf Improved new Py_TRACE_REFS gimmicks.
Arranged that all the objects exposed by __builtin__ appear in the list
of all objects.  I basically peed away two days tracking down a mystery
leak in sys.gettotalrefcount() in a ZODB app (== tons of code), because
the object leaking the references didn't appear in the sys.getobjects(0)
list.  The object happened to be False.  Now False is in the list, along
with other popular & previously missing leak candidates (like None).
Alas, we still don't have a choke point covering *all* Python objects,
so the list of all objects may still be incomplete.

Neal Norwitz 3e59076b1d Fix SF bug #690435, apply fails to check if warning raises exception
(patch provided by Greg Chapman)
2003-02-23 21:45:43 +00:00
Guido van Rossum 4b499dd3fb - Finally fixed the bug in compile() and exec where a string ending
with an indented code block but no newline would raise SyntaxError.
  This would have been a four-line change in parsetok.c...  Except
  codeop.py depends on this behavior, so a compilation flag had to be
  invented that causes the tokenizer to revert to the old behavior;
  this required extra changes to 2 .h files, 2 .c files, and 2 .py
  files.  (Fixes SF bug #501622.)
2003-02-13 22:07:59 +00:00
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
Tim Peters 2c646c9fc1 Squashed compiler wng about signed/unsigned clash in comparison. 2003-02-10 14:48:29 +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).
2003-02-10 13:19:13 +00:00
Just van Rossum b9b8e9cf6d My previous checkin caused compile() to no longer accept buffers, as noted
my MAL. Fixed. (Btw. eval() still doesn't take buffers, but that was so
even before my patch.)

Just van Rossum 3aaf42c613 patch #683515: "Add unicode support to compile(), eval() and exec"

Walter Dörwald c3da83fcd7 Make sure filter() never returns tuple, str or unicode
subclasses. (Discussed in SF patch #665835)
2003-02-04 20:24:45 +00:00
Walter Dörwald 531e000d2e PyUnicode_Resize() doesn't free its argument in case of a failure,
so we can jump to the error handling code that does.
(Spotted by Neal Norwitz)
2003-02-04 16:57:49 +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.
