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.

When creating a class, set its __module__ attribute to the module

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

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).

Rename roundup() to roundupsize(), as there's a macro roundup() in the

SystemError: bad argument to internal function

fbbd57e4ca
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
1f39c5c666
Added separate free list for cfunction (builtin method) objects, for a

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.

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

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.

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.

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

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

1997-05-10 22:07:25 +00:00
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.

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

Reindented the whole table.
1997-01-29 04:45:16 +00:00
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.

When a recycled frame has more local+stack slots than needed,

Forget keeping track of whether a dictionary contains all interned

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.

PySequence_Index(): set exception when object is not found in

Some more tuning of quicksort: use pointers instead of indexing.
1996-12-11 23:57:39 +00:00
3f236dee3a
Added new quicksort implementation, tailored to sorting arrays of

Experimental new implementation of dictionary comparison. This

Ellipses -> Ellipsis rename (the dictionary really says that it should

...
- define tp_getattro, tp_setattro
- use precreated string objects for most common exceptions and method names

Fix obscure bug in string%mapping where the mapping creates its items

Added __name__ attribute to class instance method objects.
...
Removed im_doc attribute; __name__ and __doc__ are now handled by
