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).

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).

Added _Fini() routines to free up some memory
1997-08-05 02:16:08 +00:00
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

Added separate free list for cfunction (builtin method) objects, for a

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.

In _Py_PrintReferences(), no longer suppress once-referenced string.

Avoid function calls to access the current thread state and builtins

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

Renamed a local variable from 'PyCFunction' (which is also a typedef

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.

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.

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().)

Rewrite readlines() to speed it up -- about a factor of 2 on my

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.
