Guido van Rossum 474b19e2ab Make sure that PyDict_GetItem[String]() *never* raises an exception.
If the argument is not a dictionary, simply return NULL.  If the
hash() on the key fails, clear the error.

Guido van Rossum 9b00dfae75 If USE_STACKCHECK is defined use PyOS_CheckStack() in the repr and str
routines. This catches a slightly different set of crashes than the
recursive-repr fix.

Guido van Rossum fb376dee55 Use Py_Repr{Enter,Leave} to display recursive lists in finite space.

Guido van Rossum 240c35aac0 Subtle fix in the read() code which could cause a read broken up in
several pieces to fail...

Guido van Rossum f8b4de02a4 When we have no setvbuf(), make the file totally unbuffered using
setbuf() if a buffer size of 0 or 1 byte is requested.
1998-03-06 15:32:40 +00:00
Guido van Rossum dcb5e7f389 Of course, I shouldn't have used lseek() to find out the file's
position in new_buffersize(); the correct function to use is ftell().
Thanks to Ben Jackson.
1998-03-03 22:36:10 +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)
1998-02-25 17:50:03 +00:00
Guido van Rossum f1dc0615e9 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).
1998-02-19 20:51:52 +00:00
Guido van Rossum bde6ff7984 Vladimir Marangozov' performance hack: copy f_builtins from ancestor
if the globals are the same.

Also, when creating a dummy builtins dictionary, add "None" to it,
just to be kind.

Guido van Rossum 3da3fcef96 Check ferror(), not errno, for fread() error. 1998-02-19 20:46:48 +00:00
Guido van Rossum db9351643d Instead of "attribute-less object", issue an error message that
contains the type of the object and name of the attribute.
1998-01-19 22:16:36 +00:00
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 b7f1afe4a8 Change the default repr() and str() of class instance objects to look
like <modulename.classname instance at ...> (to match the repr() of
class objects.
1997-12-03 00:06:02 +00:00
Guido van Rossum 242c64256c 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.
1997-11-19 16:03:17 +00:00
Guido van Rossum 3931df9250 Undo another glitch of the automatic not-so-Grand Renaming; some local
variables called 'coerce' were accidentally renamed to
'PyNumber_Coerce'.  Rename them back to coercefunc.
1997-11-18 19:23:07 +00:00
Guido van Rossum f51815426e Fix problem discovered by Barry: if you hit ^C to
sys.stdin.readline(), you get a fatal error (no current thread).  This
is because there was a call to PyErr_CheckSignals() while there was no
current thread.  I wonder how many more of these we find...  I bnetter
go hunting for PyErr_CheckSignals() now...
1997-11-07 19:20:34 +00:00
Guido van Rossum 6345ac6d61 Add cast to realloc/malloc call to shut up AIX compiler. (Vladimir Marangozov) 1997-10-31 20:32:13 +00:00
Guido van Rossum 3c03fa87b6 Hack suggested by Matthias Klose to pull in all relevant entry points
in libmath.a so they are available to mathmodule.so (in case it is
shared).  While this still gets triggered on Solaris 2.x, this appears
to be harmless there.
1997-10-31 17:00:30 +00:00
Guido van Rossum 1f84449fd8 New CObject from Jim Fulton, adds PyCObject_FromVoidPtrAndDesc() and
PyCObject_GetDesc().
1997-10-21 19:48:35 +00:00
Guido van Rossum 4a2a621907 Write a str() function for class objects that returns
"modulename.classname" instead of returning the same as repr().
1997-10-20 23:26:11 +00:00
Guido van Rossum 6fcfa72c63 Correct Barry's fix -- take care of {}.get(0). 1997-10-20 20:10:00 +00:00
Barry Warsaw 320ac331d1 dict_get(): Fixed a couple of stupid mistakes which caused crashes.
Also got rid of some unnecessary code.
1997-10-20 17:26:25 +00:00
Guido van Rossum 04d73c495e Check that all base classes are indeed class objects, rather than
expecting the caller to do so.
1997-10-07 14:54:11 +00:00
Barry Warsaw c38c5da5d0 dict_get(): New method for item access with different semantics than
__getitem__().  This method never raises an exception; if the key is
not in the dictionary, the second (optional) argument is returned.  If
the second argument is not provided and the key is missing, None is
returned.

mapp_methods: added "get" method.
1997-10-06 17:49:20 +00:00
Guido van Rossum 4f3bf1e383 Don't intern the key string for getitem and delitem. 1997-09-29 23:31:11 +00:00
Guido van Rossum 7cc56eb524 When creating a class, set its __module__ attribute to the module
whose name is in the current globals' __name__ variable.  If __name__
is not set, ignore this.
1997-09-12 20:04:46 +00:00
Guido van Rossum 045e688f6f Patch submitted by Brad Howes (with one bug fixed by me): allow
arbitrary nested parens in a %(...)X style format.
#Also folded two lines and added more detail to the error message for
#unsupported format character.
1997-09-08 18:30:11 +00:00
Guido van Rossum b2173c3146 Allow assignments to instance.__dict__ and instance.__class__. The
former lets you give an instance a set of new instance vars.  The
latter lets you give it a new class.  Both are typechecked and
disallowed in restricted mode.

For classes, the check for read-only special attributes is tightened
so that only assignments to __dict__, __bases__, __name__,
__getattr__, __setattr__, and __delattr__ (these could be made to work
as well, but I don't know if that's useful -- let's see first whether
mucking with instances will help).
1997-08-25 21:23:56 +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).
1997-08-25 18:36:23 +00:00
Guido van Rossum 36f8e2d1db Use lseek instead of ftell; compensate by adding BUFSIZE 1997-08-21 02:31:25 +00:00
Guido van Rossum fd7a0b871f Made lookdict nearly twice as fast, resulting in a 5% overall
improvement of pystone.  Vladimir Marangozov.

Guido van Rossum 787bdd37a0 PyTuple_SetItem should require that the tuple's refcnt is one! 1997-08-17 16:25:45 +00:00
Guido van Rossum ea46e4d93c Fix mixup about PyErr_NoMemory() prototype. 1997-08-12 14:54:54 +00:00
Guido van Rossum 83f9ad8399 Fix bug in comparing function objects detected by Sjoerd:
SystemError: bad argument to internal function

caused by comparing NULL pointer default args.
1997-08-05 16:51:05 +00:00
Guido van Rossum fbbd57e4ca Added _Fini() routines to free up some memory 1997-08-05 02:16:08 +00:00
Guido van Rossum 971a7aaeac Change the Fini function to only remove otherwise unreferenced strings
from the interned table.  There are references in hard-to-find static
variables all over the interpreter, and it's not worth trying to get
rid of all those; but "uninterning" isn't fair either and may cause
subtle failures later -- so we have to keep them in the interned
table.

Also get rid of no-longer-needed insert of None in interned dict.
1997-08-05 02:15:12 +00:00
Guido van Rossum 1f39c5c666 Added separate free list for cfunction (builtin method) objects, for a
few percent speed up.  Also add PyCFunction_Fini() to discard it.
1997-08-05 02:11:41 +00:00
Guido van Rossum 404b95d9ba Provide a dummy empty directory as f_builtins instead of failing, when
no valid directory is passed in.  This prevents __del__ to fail when
invoked after __builtins__ has already been discarded.

Also add PyFrame_Fini() to discard the cache of frames.
1997-08-05 02:09:46 +00:00
Guido van Rossum a0d349f46a Added separate free list for instance method objects, for a few
percent speed up.  Also add PyMethod_Fini() to discard it.
1997-08-05 02:06:53 +00:00
Guido van Rossum e09fb55f29 Added _Py_ResetReferences(), if tracing references.
In _Py_PrintReferences(), no longer suppress once-referenced string.

Add Py_Malloc and friends and PyMem_Malloc and friends (malloc
wrappers for third parties).
1997-08-05 02:04:34 +00:00
Guido van Rossum eb46d67ce5 Avoid function calls to access the current thread state and builtins
-- the thread state is passed in as an argument and the builtins are a
member thereof.
1997-08-02 02:59:08 +00:00
Guido van Rossum 8cf0476474 Added internal routine PyString_Fini() which deletes all interned
strings.  For use in Py_Finalize() only.
1997-08-02 02:57:45 +00:00
Guido van Rossum f6ca6aa869 New build procedure. 1997-07-19 19:39:57 +00:00
Guido van Rossum 5d8123f34a Reordered list of methods to hopefully put the most frequently used
ones near the front.
1997-07-13 03:58:01 +00:00
Guido van Rossum 74ba24758e Reordered list of methods to hopefully put the most frequently used
ones near the front.

Also added a missing "return -1" to PyFile_WriteString.
1997-07-13 03:56:50 +00:00
Guido van Rossum 71160aaffe Use #include "mymath.h" instead of declaring fabs() explicitly.
This should solve a weird problem on the Mac for Jack.
1997-06-03 18:03:18 +00:00
Guido van Rossum a8d5131d57 Renamed dict.absorb() (too spungy) to dict.update(). 1997-06-02 17:13:37 +00:00
Guido van Rossum 80c2a1674e American spelling in doc string. 1997-06-02 14:43:07 +00:00
Guido van Rossum e3f5b9c8d1 Added dict.absorb() and dict.copy(). 1997-05-28 19:15:28 +00:00
Guido van Rossum c8b6df9004 PyObject_Compare can raise an exception now. 1997-05-23 00:06:51 +00:00
Guido van Rossum 5b2121b25f PyObject_Compare can now return an error. Unfortunately, there are a
few places where we don't know how to test for them without losing
speed; don't know yet how to handle that.
1997-05-23 00:01:41 +00:00
Guido van Rossum 27a60b147c PyFile_WriteString now returns an error indicator instead of calling
PyErr_Clear().
1997-05-22 22:25:11 +00:00
Guido van Rossum e9eec54798 Fix typo in error checking spotted by Just... 1997-05-22 14:02:25 +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.
1997-05-20 22:09:08 +00:00
Guido van Rossum 037b2205e8 Moved PyObject_{Get,Set}Attr to object.c.
Fixed two 'return NULL' that should be 'return -1'.
1997-05-20 18:35:19 +00:00
Guido van Rossum 98ff96adba Moved PyObject_{Get,Set}Attr here (from dictobject) and add PyObject_HasAttr. 1997-05-20 18:34:44 +00:00
Guido van Rossum 967839473a Got rid of c_error in favor of errno (and EDOM/ERANGE).
Assume that errno usage is thread-safe -- most vendors do this by
making in a macro that refers to a per-thread storage area.
1997-05-20 18:21:34 +00:00
Guido van Rossum 3cca24570e Got rid of all the last_name_* bogosities. I don't think the
complexity saved much any more.  A simple benchmark (grail) showed
that there were 3 times as many misses as hits, and the same number of
times again the code was bypassed altogether due to the existence of
setattro/getattro.
1997-05-16 14:23:33 +00:00
Guido van Rossum d0c87ee6c4 Oops, another forgotten renaming: varobject -> PyVarObject. 1997-05-15 21:31:03 +00:00
Guido van Rossum e61093c218 Fix reversed test for failure in PySequence_List() and PySequence_Tuple().
This broke cPickle.
1997-05-14 18:43:29 +00:00
Guido van Rossum 9637432265 Renamed mappingobject.c to dictobject.c. 1997-05-13 21:05:38 +00:00
Guido van Rossum a9e7a81137 Renamed from mappingobject.c to dictobject.c.
(Sorry Jack, all your projects will have to be changed again. :-( )
1997-05-13 21:02:11 +00:00
Guido van Rossum 93ad0df06c Faster floating point allocator, same idea as the int allocator.
By Aaron Watters.
1997-05-13 21:00:42 +00:00
Guido van Rossum 789a1613a0 Add optional 'sizehint' argument to readlines(). After approximately
this many bytes have been read, readlines stops.  Because of
buffering, the amount of bytes read is usually at least 8K more than
the hint.

Also changed read() and readline() to use PyArg_ParseTuple().

(Note that the *previous* checkin also fixed error handling and
narrowed the range of thread unblocking for all methods using
fread().)
1997-05-10 22:33:55 +00:00
Guido van Rossum 6263d5451c Rewrite readlines() to speed it up -- about a factor of 2 on my
Indigo2, reading a 9Meg file from the local disk.
1997-05-10 22:07:25 +00:00
Guido van Rossum 5449b6e123 Speed up read() (i.e. read till EOF) considerably by doing a stat() to
see if we can guess the #bytes until the end of the file.  If we
can't, increment the buffer size increments up to 0.5Meg to avoid
realloc'ing too much.
1997-05-09 22:27:31 +00:00
Guido van Rossum 0add15f6a5 removed last #ifdef SUPPORT_OBSOLETE_ACCESS bits. 1997-05-09 01:07:15 +00:00
Guido van Rossum b819914263 Fix by Mark Hammond to enable truncate() on Windows. 1997-05-06 15:23:24 +00:00
Guido van Rossum fdf95dd525 Checkin of Jack's buffer mods.
Not really checked, but didn't fail any tests either...
1997-05-05 22:15:02 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management.
All per-thread globals are moved into a struct which is manipulated
separately.
1997-05-05 20:56:21 +00:00
Guido van Rossum c0b618a2cc Quickly renamed the last directory. 1997-05-02 03:12:38 +00:00
Guido van Rossum 1875247549 Quickly renamed. 1997-04-29 14:49:28 +00:00
Guido van Rossum 3648884490 (Jack:) Align mapping entries to 4-words if USE_CACHE_ALIGNED is defined. 1997-04-11 19:14:07 +00:00
Guido van Rossum 2095d24842 Tweaks to keep the Microsoft compiler quiet. 1997-04-09 19:41:24 +00:00
Guido van Rossum 8017767420 Remove unused variable. 1997-04-09 18:22:28 +00:00
Guido van Rossum 6191551ad6 Remove a redundant XINCREF(value). This caused the reference count of
all locals to be upped by one when `from <module> import <whatever>'
was executed.
1997-04-03 18:31:43 +00:00
Guido van Rossum 4669fb474b Several fixes reported by jim F. 1997-04-02 05:31:09 +00:00
Guido van Rossum c054d70aee Get rid of .conj pseudo data attribute for complex numbers.
Add __members__ attribute.
1997-04-01 03:12:33 +00:00
Guido van Rossum fb8f1cadb2 Add clear() method to dictionary objects. 1997-03-21 21:55:12 +00:00
Guido van Rossum f2e499b1d7 New long_lshift, without restriction on size of shift count, by Tim Peters.
This makes it possible to write 1L<<1000000, memory permitting.
1997-03-16 00:37:59 +00:00
Guido van Rossum 45b83915f8 New form of PyFPE_END_PROTECT macro. 1997-03-14 04:32:50 +00:00
Guido van Rossum 19700b6a98 Add casts to CMPERROR macro to silence SunPro compiler warnings about
integer overflow in << operator.
1997-03-05 00:45:43 +00:00
Guido van Rossum 09e6ad0c1e Changes for Lee Busby's SIGFPE patch set.
Surround various f.p. operations with  PyFPE_{START,END}_PROTECT macros.
1997-02-14 22:54:21 +00:00
Guido van Rossum 0f4bbd2f34 Keep gcc -Wall happy. 1997-02-14 21:12:56 +00:00
Guido van Rossum 36b9f7908a Slight tweak: in string_hash(), if the hash hasn't been computed yet,
and if there's a pointer to an interned version of the string, use its
hash and store its hash in this object, rather than recomputing it.
1997-02-14 16:29:22 +00:00
Guido van Rossum 7582bfb60a Kill all local variables when the frame is deallocated (moved here
from ceval.c).

Wrapped a long line.
1997-02-14 16:27:29 +00:00
Guido van Rossum efb4609c4a Small lookmapping nits:
- remove bogus initialization using uninitialized i
- derive initial incr from hash
- copy mp->ma_table into a local variable
1997-01-29 15:53:56 +00:00
Guido van Rossum 4acdc2327f Fix bug reported by Per Lindqvist: "%#06x" % 1 stuck the 0 padding
in front of the 0x, like such: "0000x1".
1997-01-29 06:00:24 +00:00
Guido van Rossum 9e5656ca3f Final three poly table entries corrected by Tim Peters.
Reindented the whole table.
1997-01-29 04:45:16 +00:00
Guido van Rossum 16e93a8d59 Changed the lookup algorithm again, based on Reimer Behrends's post.
The table size is now constrained to be a power of two, and we use a
variable increment based on GF(2^n)-{0} (not that I have the faintest
idea what that is :-) which helps avoid the expensive '%' operation.

Some of the entries in the table of polynomials have been modified
according to a post by Tim Peters.
1997-01-28 00:00:11 +00:00
Guido van Rossum 747596a491 When a recycled frame has more local+stack slots than needed,
give the extra slots to the stack rather than than forgetting about
them (this reduces the number of reallocs done).
1997-01-24 04:00:21 +00:00
Guido van Rossum ca756f2a1d Forget keeping track of whether a dictionary contains all interned
string keys.  Just doing a pointer compare before the string compare
(in fact before the hash compare!) is just as fast.

Guido van Rossum e0e696282f Added PyCObject_Import. 1997-01-22 20:48:48 +00:00
Guido van Rossum a04d47b319 Don't use static buffers internally for formatstring(). 1997-01-21 16:12:09 +00:00
Guido van Rossum 3bb63a8dbe Bugfix: remove ref to fast before it's defined. 1997-01-20 04:29:16 +00:00
Guido van Rossum 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.

Guido van Rossum a412d24be0 Intern the various string objects created to speed up lookups. 1997-01-18 07:59:12 +00:00
Guido van Rossum b56933ed2e Intern the strings "__builtins__". 1997-01-18 07:58:41 +00:00

Guido van Rossum 2a61e7428d String interning. 1997-01-18 07:55:05 +00:00
Guido van Rossum 792fd435ec Comment out extend_stack() -- it is no longer needed. 1997-01-17 21:07:57 +00:00
Guido van Rossum 7d18159614 Rewrote lookmapping() according to suggestions by Jyrki Alakuijala. 1997-01-16 21:06:45 +00:00
Guido van Rossum 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
Guido van Rossum ebee0256f3 Changed hex() and oct() again, to never emit a '-' sign. 1997-01-12 19:48:03 +00:00
Guido van Rossum 919cf1aff1 New, better hash for floating point and complex 1997-01-11 19:26:21 +00:00
Guido van Rossum 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
Guido van Rossum 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
Guido van Rossum 53756b1097 Added PyLong_FromUnsignedLong() and PyLong_AsUnsignedLong(). 1997-01-03 17:14:46 +00:00
Guido van Rossum babab6869f Removed all traces of accessobject.c. 1996-12-25 19:22:49 +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.
1996-12-18 19:32:18 +00:00
Guido van Rossum 0969ad213d Better tuple hash function. 1996-12-16 17:55:46 +00:00
Guido van Rossum cc15b42e59 Change comment about MINSIZE -- 10 is optimal for Python. 1996-12-16 03:32:39 +00:00
Guido van Rossum 3176bb1df2 Some more tuning of quicksort: use pointers instead of indexing. 1996-12-11 23:57:39 +00:00
Guido van Rossum 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.

Guido van Rossum 067998f35e Add const to error and newstring functions 1996-12-10 15:33:34 +00:00
Guido van Rossum 9478dd40c2 Fix core dump from pow(x,y,0).
Make gcc -Wall happy.

Guido van Rossum 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
Guido van Rossum 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
Guido van Rossum 685a38ea94 Make gcc -Wall happy. 1996-12-05 21:54:17 +00:00
Guido van Rossum 04f95d5238 Better implementation of PyCObject_AsVoidPtr(). 1996-12-05 21:53:15 +00:00
Guido van Rossum cbd1e4eb5f Yet more elaborate message for exception in __del__.
Make gcc -Wall happy.
1996-12-05 21:52:32 +00:00
Guido van Rossum 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
Guido van Rossum 052b7e1cfb Make Py_ReturnNullError() statis as it should be. 1996-11-11 15:08:19 +00:00
Guido van Rossum 08ef9d98b2 Only call sq_length in Sequence_GetItem for negative index. 1996-11-09 22:32:05 +00:00
Guido van Rossum 8dbcdd0a4c correct typo in return variable for PySequence_Index() 1996-11-06 15:31:46 +00:00
Guido van Rossum d266eb460e New permission notice, includes CNRI. 1996-10-25 14:44:06 +00:00
Guido van Rossum 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
Guido van Rossum 8bcf369cf9 Support passing in an empty dictionary of keywords to newinstanceobject. 1996-10-21 15:12:32 +00:00
Guido van Rossum 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
Guido van Rossum 336c699236 Fix subtle bug detected by Jim F. 1996-09-30 22:00:50 +00:00

Guido van Rossum 3be12e97cd Properly(?) implemented remainder and divmod (Tim Hochberg) 1996-09-12 20:56:18 +00:00
Guido van Rossum d4ab3cde8e Raise exception instead of dropping imag part for conversion to int,
long, float.

Raise exception instead of dumping core for remainder and divmod.
