Tim Peters 0e76ab2ecc Use METH_VARARGS instead of "1" in list method table. 2000-12-13 22:35:46 +00:00
Fred Drake d5fadf75e4 Rationalize use of limits.h, moving the inclusion to Python.h.
Add definitions of INT_MAX and LONG_MAX to pyport.h.
Remove includes of limits.h and conditional definitions of INT_MAX
and LONG_MAX elsewhere.

This closes SourceForge patch #101659 and bug #115323.

Guido van Rossum 8586991099 REMOVED all CWI, CNRI and BeOpen copyright markings.
This should match the situation in the 1.6b1 tree.

Thomas Wouters e289e0bd0c Support for the in-place operations introduced by augmented assignment. Only
the list object supports this currently, but other candidates are
gladly accepted (like arraymodule and such.)

Thomas Wouters 334fb8985b Use 'void' directly instead of the ANY #define, now that all code is ANSI C.
Leave the actual #define in for API compatibility.

Vladimir Marangozov 467a67e74d Fix in PyList_New(). With GC enabled and when out of memory,
free() the GC pointer, not the object pointer.

Jeremy Hylton c5007aa5c3 final patches from Neil Schemenauer for garbage collection 2000-06-30 05:02:53 +00:00
Jeremy Hylton d08b4c4524 part 2 of Neil Schemenauer's GC patches:
This patch modifies the type structures of objects that
participate in GC.  The object's tp_basicsize is increased when
GC is enabled.  GC information is prefixed to the object to
maintain binary compatibility.  GC objects also define the
tp_flag Py_TPFLAGS_GC.

Jeremy Hylton 8caad49c30 Round 1 of Neil Schemenauer's GC patches:
This patch adds the type methods traverse and clear necessary for GC
implementation.

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.

Fred Drake 56780257c6 Thomas Wouters <thomas@xs4all.net>:
The following patch adds "sq_contains" support to rangeobject, and enables
the already-written support for sq_contains in listobject and tupleobject.

The rangeobject "contains" code should be a bit more efficient than the
current default "in" implementation ;-) It might not get used much, but it's
not that much to add.

listobject.c and tupleobject.c already had code for sq_contains, and the
proper struct member was set, but the PyType structure was not extended to
include tp_flags, so the object-specific code was not getting called (Go
ahead, test it ;-). I also did this for the immutable_list_type in
listobject.c, eventhough it is probably never used. Symmetry and all that.

Fred Drake b6a9ada757 Michael Hudson <mwh21@cam.ac.uk>:
Removed PyErr_BadArgument() calls and replaced them with more useful
error messages.

Guido van Rossum b18618dab7 Vladimir Marangozov's long-awaited malloc restructuring.
For more comments, read the patches@python.org archives.
For documentation read the comments in mymalloc.h and objimpl.h.

(This is not exactly what Vladimir posted to the patches list; I've
made a few changes, and Vladimir sent me a fix in private email for a
problem that only occurs in debug mode.  I'm also holding back on his
change to main.c, which seems unnecessary to me.)

Jeremy Hylton 37b1a26c89 add list_contains and tuplecontains: efficient implementations of tp_contains 2000-04-27 21:41:03 +00:00
Guido van Rossum d724b23420 Christian Tismer's "trashcan" patch:
Added wrapping macros to dictobject.c, listobject.c, tupleobject.c,
frameobject.c, traceback.c that safely prevends core dumps
on stack overflow. Macros and functions in object.c, object.h.
The method is an "elevator destructor" that turns cascading
deletes into tail recursive behavior when some limit is hit.
2000-03-13 16:01:29 +00:00
Guido van Rossum ef93b87f1c Added Christian Tismer's patch to allow list.append(a,b,c) back --
with a twist: you have to define NO_STRICT_LIST_APPEND manually
to enable multi-arg append().
2000-03-13 15:41:59 +00:00
Guido van Rossum c00a938be8 OKOK, Greg's right, I should've used the :name option in the argument
format strings.
2000-02-24 21:48:29 +00:00
Guido van Rossum 4aa24f9979 Made all list methods use PyArg_ParseTuple(), for more accurate
diagnostics.

*** INCOMPATIBLE CHANGE: This changes append(), remove(), index(), and
*** count() to require exactly one argument -- previously, multiple
*** arguments were silently assumed to be a tuple.

Guido van Rossum bffd683f73 The rest of the changes by Trent Mick and Dale Nagata for warning-free
compilation on NT Alpha.  Mostly added casts etc.

Guido van Rossum fa71701d46 When deallocating a list, DECREF the items from the end back to the start. 1999-06-09 15:19:34 +00:00
Guido van Rossum 9bcd1d7931 Improve text of some error messages, as suggested by Sean Reifschneider. 1999-04-19 17:44:39 +00:00
Guido van Rossum 3aa23fdd47 Jim Ahlstrom patch: cutoff should be a long for machines with 16-bit
ints.  (In theory, other variables should be widened to long as well,
but this won't ever be needed, since the len of a list is still an
int.)

Barry Warsaw dedf6d6804 listextend(): New method which implements L.extend(L2). 1998-10-09 16:37:25 +00:00
Guido van Rossum 2ccaf6f2f9 Remove a redundant check from list_slice() and list_ass_slice().
Noted by Greg Stein.

Guido van Rossum 3dd7f3fef0 Added doc strings for methods and a new pop() method. 1998-06-30 15:36:32 +00:00
Guido van Rossum 4281258b5f Minor cleanup by Tim after my changes:
+ Took the "list" argument out of the other functions that no longer need
it.  This speeds things up a little more.

+ Small comment changes in accord with that.

+ 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
of registers 12 iterations ago.  It should yield a small speedup on a RISC
machine, and not hurt in any case.
1998-06-17 14:15:44 +00:00
Guido van Rossum 4c4e7df755 Tim's latest, with some of my changes (also a TP suggestion) added:
instead of testing whether the list changed size after each
comparison, temporarily set the type of the list to an immutable list
type.  This should allow continued use of the list for legitimate
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.)
1998-06-16 15:18:28 +00:00
Guido van Rossum a119c0dd5e Tim's revision of the previous patch. He also added some sparts to
the median-of-three code to get a few percent back.

(Jeremy will hardly recognize his patch :-)
1998-04-10 22:47:27 +00:00
Guido van Rossum 044b9dc1d7 Add back some safeguards on the index elements that were lost in the
last patch.  Dave Ascher found a case that dumps core without these:

def myComparison(x,y):
    return cmp(x%3,y%7)

z = range(12)
z.sort(myComparison)

Guido van Rossum 24e62e2c7c Modified quicksort by Raymund Galvin, after studying the GNU libg++
quicksort.  This should be much faster if there are lots of
duplicates, and otherwise at least as good.
1997-12-10 15:14:24 +00:00
Guido van Rossum a27d112213 Rename roundup() to roundupsize(), as there's a macro roundup() in the
sys/types.h header on many systems that may get pulled in (through
WANT_SIGFPE_HANDLER which pulls in signal.h).
