Andrew M. Kuchling 74042d6e5d Patch from /F:
this patch introduces PySequence_Fast and PySequence_Fast_GET_ITEM,
and modifies the list.extend method to accept any kind of sequence.

Guido van Rossum 9e896b37c7 Marc-Andre's third try at this bulk patch seems to work (except that
his copy of test_contains.py seems to be broken -- the lines he
deleted were already absent).  Checkin messages:


New Unicode support for int(), float(), complex() and long().

- new APIs PyInt_FromUnicode() and PyLong_FromUnicode()
- added support for Unicode to PyFloat_FromString()
- new encoding API PyUnicode_EncodeDecimal() which converts
  Unicode to a decimal char* string (used in the above new
  APIs)
- shortcuts for calls like int(<int object>) and float(<float obj>)
- tests for all of the above

Unicode compares and contains checks:
- comparing Unicode and non-string types now works; TypeErrors
  are masked, all other errors such as ValueError during
  Unicode coercion are passed through (note that PyUnicode_Compare
  does not implement the masking -- PyObject_Compare does this)
- contains now works for non-string types too; TypeErrors are
  masked and 0 returned; all other errors are passed through

Better testing support for the standard codecs.

Misc minor enhancements, such as an alias dbcs for the mbcs codec.

Changes:
- PyLong_FromString() now applies the same error checks as
  does PyInt_FromString(): trailing garbage is reported
  as error and not longer silently ignored. The only characters
  which may be trailing the digits are 'L' and 'l' -- these
  are still silently ignored.
- string.ato?() now directly interface to int(), long() and
  float(). The error strings are now a little different, but
  the type still remains the same. These functions are now
  ready to get declared obsolete ;-)
- PyNumber_Int() now also does a check for embedded NULL chars
  in the input string; PyNumber_Long() already did this (and
  still does)

Followed by:

Looks like I've gone a step too far there... (and test_contains.py
seem to have a bug too).

I've changed back to reporting all errors in PyUnicode_Contains()
and added a few more test cases to test_contains.py (plus corrected
the join() NameError).

Guido van Rossum 4c08d554b9 Many changes for Unicode, by Marc-Andre Lemburg. 2000-03-10 22:55:18 +00:00
Guido van Rossum 9611e0b462 Patch by Moshe Zadka: remove the string special case in
PySequence_Contains() now that string objects have this code in their
tp_contains.

Guido van Rossum 46c6b20392 Patch by Mozhe Zadka, for __contains__ (overloading 'in'). This
patches PySequence_Contains() to check for a valid sq_contains field.
More to follow.

Andrew M. Kuchling 0f223d2418 Allow using long integers as arguments to PyObject_GetItem(), _SetItem(),
and _DelItem().
In sequence multiplication by a long, only call PyErr_Occurred() when the
    value returned is -1.

Guido van Rossum 031d0e5feb Patch by Charles Waldman -- remove unneeded and even harmful test for
float to the negative power (which is already and better done in
floatobject.c.)

Guido van Rossum f5046d1aea Remove prototype for PyOS_strtol -- Chris Herborth. 1998-12-10 16:54:48 +00:00
Guido van Rossum 9d904b9389 Believe it or not, Solaris 2.6 strtod() can move the end pointer
*beyond* the null byte at the end of the input string, when the input
is inf(inity).  Discovered by Greg Ward.

Guido van Rossum 21308243ca Better error messages when a sequence is indexed with a non-integer.
Previously, this said "unsubscriptable object"; in 1.5.1, the reverse
problem existed, where None[''] would complain about a non-integer
index.  This fix does the right thing in all cases (for get, set and
del item).
1998-08-13 16:44:44 +00:00
Guido van Rossum df3d8756b7 Better error messages when raising ValueError for int and long
literals.  (The previous version of this code would not show the
offending input, even though there was code that attempted this.)
1998-08-04 15:02:01 +00:00
Guido van Rossum 5dba9e8aef Add special case to PySequence_List() so that list() of a list is
faster (using PyList_GetSlice()).  Also added a test for a NULL
argument, as with PySequence_Tuple().  (Hmm...  Better names for these
two would be PyList_FromSequence() and PyTuple_FromSequence().  Oh well.)
1998-07-10 18:03:50 +00:00
Guido van Rossum bfc725bf64 Changed PySequence_List() and PySequence_Tuple() to support
"indefinite length" sequences.  These should still have a length, but
the length is only used as a hint -- the actual length of the sequence
is determined by the item that raises IndexError, which may be either
smaller or larger than what len() returns.  (This is a novelty; map(),
filter() and reduce() only allow the actual length to be larger than
what len() returns, not shorter.  I'll fix that shortly.)
1998-07-10 16:22:44 +00:00
Guido van Rossum 3b2b34790f Fix the tests for various anomalies in the string-to-numbers
conversions.  Formerly, for example, int('-') would return 0 instead
of raising ValueError, and int(' 0') would raise ValueError
(complaining about a null byte!) instead of 0...
1998-06-22 03:54:15 +00:00
Guido van Rossum ed6219b116 Fix a whole bunch of error return NULL that should be return -1. 1998-05-29 02:59:33 +00:00
Guido van Rossum 08570decb7 Uses PyErr_ExceptionMatches() instead of comparing PyErr_Occurred(). 1998-05-28 19:24:35 +00:00
Guido van Rossum fa0b6ab01a Address some gcc -Wall warnings (e.g. include <ctype.h>).
Make sure that no tp_as_numbers->nb_<whatever> function is called
without checking for a NULL pointer.  Marc-Andre Lemburg will love it!
(Except that he's just rewritten all this code for a different
approach to coercions ;-( )
1998-05-22 15:23:36 +00:00
Guido van Rossum cea1c8ca22 Completely reformatted, standardizing indentation as well as
programming style.

Recoded many routines to incorporate better error checking, and/or
better versions of the same function found elsewhere
(e.g. bltinmodule.c or ceval.c).  In particular,
Py_Number_{Int,Long,Float}() now convert from strings, just like the
built-in functions int(), long() and float().

Sequences and mappings are now safe to have NULL function pointers
anywhere in their tp_as_sequence or tp_as_mapping fields.  (A few
places in other files need to be checked in too.)

Renamed PySequence_In() to PySequence_Contains().

Guido van Rossum f7d590c93d This was the reason a numeric array to a real power was not working. 1998-04-03 23:38:59 +00:00
Guido van Rossum a9040ec5d9 Renamed a local variable from 'PyCFunction' (which is also a typedef
in methodobject.h) to 'func'.  /bin/cc on SunOS 4.x didn't grok this.

Guido van Rossum e61093c218 Fix reversed test for failure in PySequence_List() and PySequence_Tuple().
This broke cPickle.

Guido van Rossum 4669fb474b Several fixes reported by jim F. 1997-04-02 05:31:09 +00:00
Barry Warsaw f90eddef5d PySequence_Index(): set exception when object is not found in
sequence, otherwise

operator.indexOf([4, 3, 2, 1], 9) would raise a SystemError!

Note: it might be wise to double check all these functions.  I haven't
done that yet.

Guido van Rossum 3c5936afc5 Added missing PySequence_List.
Correct typo in error msg (expec[t]ed).
Make gcc -Wall happy.
