filter() and reduce() only allow the actual length to be larger than
what len() returns, not shorter. I'll fix that shortly.)

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.

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.)

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>.

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.)

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.

Fix problem discovered by Barry: if you hit ^C to

Allow assignments to instance.__dict__ and instance.__class__. The

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).

Change the Fini function to only remove otherwise unreferenced strings

from the interned table. There are references in hard-to-find static

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.

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).

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.

1995-09-18 10:49:04 +00:00
6ec3c653da
Implemented two new functions in sys:
...
getcounts() returns a list of counts of allocations and
deallocations for all different object types.
getobjects(n [, type ]) returns a list of recently allocated
and not-yet-freed objects of the given type (all
objects if no type given). Only the n most recent
(all if n==0) objects are returned.
getcounts is only available if compiled with -DCOUNT_ALLOCS,
getobjects is only available if compiled with -DTRACE_REFS. Note that
everything must be compiled with these options!

entirely redone operator overloading. The rules for class

* Objects/floatobject.c: add overflow check when converting float
to int and implement truncation towards zero using ceil/float

write "lambda x: x+1".
* Xtmodule.c (checkargdict): return 0, not NULL, for error.

* timemodule.c: Add hack for Solaris 2.
...
* posixmodule.c: don't prototype getcwd() -- it's not portable...
* mappingobject.c: double-check validity of last_name_char in
dict{lookup,insert,remove}.
* arraymodule.c: need memmove only for non-STDC Suns.
* Makefile: comment out HTML_LIBS and XT_USE by default
* pythonmain.c: don't prototype getopt() -- it's not standardized
* socketmodule.c: cast flags arg to {get,set}sockopt() and addrbuf arg to
recvfrom() to (ANY*).
* pythonrun.c (initsigs): fix prototype, make it static
* intobject.c (LONG_BIT): only #define it if not already defined
* classobject.[ch]: remove all references to unused instance_convert()
* mappingobject.c (getmappingsize): Don't return NULL in int function.

* import.c (get_module): total rewrite, to ensure proper search order: for
...
each dir in sys.path, try each possible extension. (Note: C extensions
are loaded before Python modules in the same directory, to allow having
a C version used when dynamic loading is supported and a Python version
as a back-up.)
* import.c (reload_module): test for error from getmodulename()
* moduleobject.c: implement module name as dict entry '__name__' instead
of special-casing it in module_getattr(); this way a module (or
function!) can access its own module name, and programs that know what
they are doing can rename modules.
* stdwinmodule.c (initstdwin): strip ".py" suffix of argv[0].

Three micro fixes to formatstring
1993-11-11 14:51:57 +00:00
52f2c05401
* parsermodule.c, Makefile, config.c: rudimentary interface to the Python
...
parser.
* mappingobject.c (lookmapping): 'freeslot' was never used due to a bug in
the code.
1993-11-10 12:53:24 +00:00

* posixmodule.c: added set{uid,gid}.
...
* {tuple,list,mapping,array}object.c: call printobject with 0 for flags
* compile.c (parsestr): use quote instead of '\'' at one crucial point
* arraymodule.c (array_getattr): Added __members__ attribute
1993-11-10 09:23:53 +00:00
c600411755
* mpzmodule.c: removed redundant mpz_print function.
...
* object.[ch], bltinmodule.c, fileobject.c: changed str() to call
strobject() which calls an object's __str__ method if it has one.
strobject() is also called by writeobject() when PRINT_RAW is passed.
* ceval.c: rationalize code for PRINT_ITEM (no change in function!)
* funcobject.c, codeobject.c: added compare and hash functionality.
Functions with identical code objects and the same global dictionary are
equal. Code objects are equal when their code, constants list and names
list are identical (i.e. the filename and code name don't count).
(hash doesn't work yet since the constants are in a list and lists can't
be hashed -- suppose this should really be done with a tuple now we have
resizetuple!)

Added compare operations for functions and code objects.
...
(Also hash, but it doesn't work yet.)
