4a2a621907 Write a str() function for class objects that returns 
"modulename.classname" instead of returning the same as repr().

320ac331d1 dict_get(): Fixed a couple of stupid mistakes which caused crashes. 
Also got rid of some unnecessary code.

04d73c495e Check that all base classes are indeed class objects, rather than 
expecting the caller to do so.

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.

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.

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.

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).

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).

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.

1f39c5c666 Added separate free list for cfunction (builtin method) objects, for a 
few percent speed up.  Also add PyCFunction_Fini() to discard it.

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.

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).

eb46d67ce5 Avoid function calls to access the current thread state and builtins

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.

in methodobject.h) to 'func'.  /bin/cc on SunOS 4.x didn't grok this.

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.

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().)

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.
