bd3a527f93 Two patches by Jason Harper:
- Faster conversion to string for binary bases: linear instead of quadratic!

- Allocate smaller result for certain masking ops, e.g. (1L<<30000) & 1.

ac6a37ae55 Fix a potential problem in PyLong_FromString(): could fall through the
for loop with z==NULL but continue to reference z later.

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.)

152d8173a3 Fix a memory leak -- the cached values of __getattr__ etc. were never
freed.

52ddc0e756 PyFile_FromString(): If an exception occurs, pass in the filename that
was used so it's reflected in the IOError.  Call
PyErr_SetFromErrnoWithFilename().

b4db1944c4 When comparing objects, always check that tp_compare is not NULL
before calling it.  This check was there when the objects were of the
same type *before* coercion, but not if they initially differed but
became the same *after* coercion.

0fd00334c6 Avoid using calloc(). This triggered an obscure bug on multiprocessor
Sparc Solaris 2.6 (fully patched!) that I don't want to dig into, but
which I suspect is a bug in the multithreaded malloc library that only
shows up when run on a multiprocessor.  (The program wasn't using
threads, it was just using the multithreaded C library.)

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.)

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.)

d4ba73c75b Move the definition of PyMethodObject to classobject.h, so it can define
macros for more efficient access to the fields.

8a92c627d9 New feature: if the object's type has a non-NULL tp_doc field, that
is returned as the object's __doc__ attribute.

(If only the list of methods would be referenced from the type...)

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...

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.

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.)

cd5a5f627a When comparing objects of different types (which is done by comparing
the type names), make sure that numeric objects are considered smaller
than all other objects, by forcing their name to "".

4a0144c0de Should check that PyObject_Str() really returned a string! 1998-06-09 15:08:41 +00:00
Guido van Rossum
a63eff6e6a Allow assignments to special class attributes -- with typechecks, and
not in restricted mode.

__dict__ can be set to any dictionary; the cl_getattr, cl_setattr and
cl_delattr slots are refreshed.

__name__ can be set to any string.

__bases__ can be set to to a tuple of classes, provided they are not
subclasses of the class whose attribute is being assigned.

__getattr__, __setattr__ and __delattr__ can be set to anything, or
deleted; the appropriate slot (cl_getattr, cl_setattr, cl_delattr) is
refreshed.

(Note: __name__ really doesn't need to be a special attribute, but
that would be more work.)
