Fix bug discovered by John W. Shipman -- when the width of a format
...
specifier came from an int expression instead of a constant in the
format, a negative width was truncated to zero instead of taken to
mean the same as that negative constant plugged into the format. E.g.
"(%*s)" % (-5, "foo") yielded "(foo)" while "(%-5s)" yields "(foo )".
Now both yield the latter -- like sprintf() in C.

what len() returns, not shorter. I'll fix that shortly.)

+ Exploited the now-safe ability to cache values in the partitioning loop.
Makes no timing difference on my flavor of Pentium, but this machine ran out

instead of testing whether the list changed size after each

purposes but disallows all operations that can change it in any way.
(Changes to the internals of list items are not caught, of cause;
that's not possible to detect, and it's not necessary to protect the
sort code, either.)

Subject: Buglet in PyLong_AsLong
...
From: "Tim Peters" <tim_one@email.msn.com>
To: "Guido van Rossum" <guido@CNRI.Reston.VA.US>
Date: Sat, 23 May 1998 21:45:53 -0400
Guido, the overflow checking in PyLong_AsLong is off a little:
1) If the C in use sign-extends right shifts on signed longs, there's a
spurious overflow error when converting the most-negative int:
Python 1.5.1 (#0 , Apr 13 1998, 20:22:04) [MSC 32 bit (Intel)] on win32

>>> x
-2147483648L
>>> int(x)
Traceback (innermost last):
File "<stdin>", line 1, in ?
OverflowError: long int too long to convert
>>>
2) If C does not sign-extend, some genuine overflows won't be caught.
The attached should repair both, and, because I installed a new disk and a C
compiler today, it's even been compiled this time <wink>.

Add internal routine _PyModule_Clear(), which does approximately what

clear_carefully() used to do in import.c. Differences: leave only
__builtins__ alone in the 2nd pass; and don't clear the dictionary (on
the theory that as long as there are references left to the
dictionary, those might be destructors that might expect __builtins__
to be alive when they run; and __builtins__ can't normally be part of
a cycle).

Add a new function PyNumber_CoerceEx() which works just like
...
PyNumber_Coerce() except that when the coercion can't be done and no
other exceptions happen, it returns 1 instead of raising an
exception.
Use this function in PyObject_Compare() to avoid raising an exception
simply because two objects with numeric behavior can't be coerced to a
common type; instead, proceed with the non-numeric default comparison.
Note that this is a somewhat questionable practice -- comparisons for
numeric objects shouldn't default to random behavior like this, but it
is required for backward compatibility. (Case in point, it broke
comparison of kjDict objects to integers in Aaron Watters' kjbuckets
extension.) A correct fix (for python 2.0) should involve a different
definiton of comparison altogether.

f3e85a0356
Changes that appear to give another 12% speedup.
...
Rather than allocating a list object for the fast locals and another
(extensible one) for the value stack and allocating the block stack
dynamically, allocate the block stack with a fixed size (CO_MAXBLOCKS
from compile.h), and stick the locals and value stack at the end of
the object (this is now possible since the stack size is known
beforehand). Get rid of the owner field and the nvalues argument --
it is available in the code object, like nlocals.
This requires small changes in ceval.c only.

Comment out extend_stack() -- it is no longer needed.
1997-01-17 21:07:57 +00:00

6f72f97c03
Increased buffer sizes used by hex() and oct() -- on 64-bit or 128-bit
...
machines, the string may get longer than 20 characters!
1997-01-14 15:43:41 +00:00
ebee0256f3
Changed hex() and oct() again, to never emit a '-' sign.
1997-01-12 19:48:03 +00:00
919cf1aff1
New, better hash for floating point and complex
1997-01-11 19:26:21 +00:00
80dd9b6672
Subtle change to hex/oct formatting so the largest negative number
...
does not receive a minus sign.
1997-01-10 17:39:30 +00:00
541cdd84ac
Fix overflow test for multiply to catch some cases it missed.
...
Added warning about dependency of float/complex hash on int hash.
1997-01-06 22:53:20 +00:00
53756b1097
Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong().
1997-01-03 17:14:46 +00:00
babab6869f
Removed all traces of accessobject.c.
1996-12-25 19:22:49 +00:00

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.
1996-12-18 19:32:18 +00:00
0969ad213d
Better tuple hash function.
1996-12-16 17:55:46 +00:00
cc15b42e59
Change comment about MINSIZE -- 10 is optimal for Python.
1996-12-16 03:32:39 +00:00

Some more tuning of quicksort: use pointers instead of indexing.
1996-12-11 23:57:39 +00:00
3f236dee3a
Added new quicksort implementation, tailored to sorting arrays of
...
object pointers. Should be a bit faster than the C library's qsort(),
and doesn't have the prohibition on recursion that Solaris qsort() has
in the threaded version of their C library.
Thanks to discussions with Tim Peters.
1996-12-10 23:55:39 +00:00

Make gcc -Wall happy
1996-12-05 21:58:58 +00:00
472c04f18f
Fix newlongobject so it will work for 64-bit as well as 32-bit hardware
...
(although for 32-bit hardware it's a bit slower than it was).
Make gcc -Wall happy.
1996-12-05 21:57:21 +00:00
a0a69b8b42
Experimental new implementation of dictionary comparison. This
...
defines that a shorter dictionary is always smaller than a longer one.
For dictionaries of the same size, the smallest differing element
determines the outcome (which yields the same results as before,
without explicit sorting).
1996-12-05 21:55:55 +00:00
685a38ea94
Make gcc -Wall happy.
1996-12-05 21:54:17 +00:00

Better implementation of PyCObject_AsVoidPtr().

Yet more elaborate message for exception in __del__.
...
Make gcc -Wall happy.
1996-12-05 21:52:32 +00:00
3c5936afc5
Added missing PySequence_List.
...
Correct typo in error msg (expec[t]ed).
Make gcc -Wall happy.
1996-12-05 21:51:24 +00:00

Make Py_ReturnNullError() statis as it should be.
1996-11-11 15:08:19 +00:00
08ef9d98b2
Only call sq_length in Sequence_GetItem for negative index.
1996-11-09 22:32:05 +00:00
8dbcdd0a4c
correct typo in return variable for PySequence_Index()
1996-11-06 15:31:46 +00:00

New permission notice, includes CNRI.
1996-10-25 14:44:06 +00:00
fde7a75b78
Fixed compare function to do first char comparison in unsigned mode,
...
for consistency with the way other characters are compared.
1996-10-23 14:19:40 +00:00
8bcf369cf9
Support passing in an empty dictionary of keywords to newinstanceobject.
1996-10-21 15:12:32 +00:00
e449af7da9
Ellipses -> Ellipsis rename (the dictionary really says that it should
...
be Ellipsis!).
Bumped the API version because a linker-visible symbol is affected.
Old C code will still compile -- there's a b/w compat macro.
Similarly, old Python code will still run, builtin exports both
Ellipses and Ellipsis.
1996-10-11 16:25:41 +00:00

Fix subtle bug detected by Jim F.

Oops... Need to clear c_error before calling c_quot().
1996-09-12 21:02:02 +00:00

Properly(?) implemented remainder and divmod (Tim Hochberg)
1996-09-12 20:56:18 +00:00
d4ab3cde8e
Raise exception instead of dropping imag part for conversion to int,
...
long, float.
Raise exception instead of dumping core for remainder and divmod.
1996-09-11 22:54:37 +00:00
22a85e5308
More detailed error message about exception in __del__
1996-09-11 22:51:57 +00:00
b7fc304109
Correct typo in setattr: return -1 for error, not NULL
1996-09-11 22:51:25 +00:00

Multiply by 1000003 instead of 3 in string hach
1996-09-11 20:22:48 +00:00

Get rid of bogus MSC_VER undef of CHECK()
1996-09-11 20:21:41 +00:00

Don't dump core on complex % or divmod -- raise a TypeError exception.
1996-09-11 13:55:55 +00:00

Use getstringsize where available instead of strlen.
1996-08-26 14:58:03 +00:00

Be a bit more careful with printing a warning for a failed __del__.
1996-08-22 23:15:42 +00:00
6cdc6f4146
Added PyObject_DelItem and PySequence_Del{Item,Slice}.
1996-08-21 17:41:54 +00:00

More efficient handling of "__doc__" lookup.
1996-08-21 14:54:28 +00:00

Write warning about exception in __del__ to stderr, not stdout.
1996-08-20 19:54:29 +00:00

Changes to make the file acceptable to K&R C compilers (HPUX, SunOS 4.x).
1996-08-19 19:30:45 +00:00
