Guido van Rossum ea46e4d93c Fix mixup about PyErr_NoMemory() prototype. 1997-08-12 14:54:54 +00:00
Guido van Rossum 83f9ad8399 Fix bug in comparing function objects detected by Sjoerd: 
SystemError: bad argument to internal function

caused by comparing NULL pointer default args.
 1997-08-05 16:51:05 +00:00
Guido van Rossum 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.
 1997-08-05 02:15:12 +00:00
Guido van Rossum 1f39c5c666 Added separate free list for cfunction (builtin method) objects, for a 
few percent speed up.  Also add PyCFunction_Fini() to discard it.
 1997-08-05 02:11:41 +00:00
Guido van Rossum 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.
 1997-08-05 02:09:46 +00:00
Guido van Rossum a0d349f46a Added separate free list for instance method objects, for a few 
percent speed up.  Also add PyMethod_Fini() to discard it.
 1997-08-05 02:06:53 +00:00
Guido van Rossum 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).
 1997-08-05 02:04:34 +00:00
Guido van Rossum eb46d67ce5 Avoid function calls to access the current thread state and builtins 
-- the thread state is passed in as an argument and the builtins are a
member thereof.
 1997-08-02 02:59:08 +00:00
Guido van Rossum 8cf0476474 Added internal routine PyString_Fini() which deletes all interned 
strings.  For use in Py_Finalize() only.
 1997-08-02 02:57:45 +00:00
Guido van Rossum f6ca6aa869 New build procedure. 1997-07-19 19:39:57 +00:00
Guido van Rossum 5d8123f34a Reordered list of methods to hopefully put the most frequently used 
ones near the front.
 1997-07-13 03:58:01 +00:00
Guido van Rossum 74ba24758e Reordered list of methods to hopefully put the most frequently used 
ones near the front.

Also added a missing "return -1" to PyFile_WriteString.
 1997-07-13 03:56:50 +00:00
Guido van Rossum 71160aaffe Use #include "mymath.h" instead of declaring fabs() explicitly. 
This should solve a weird problem on the Mac for Jack.
 1997-06-03 18:03:18 +00:00
Guido van Rossum a8d5131d57 Renamed dict.absorb() (too spungy) to dict.update(). 1997-06-02 17:13:37 +00:00
Guido van Rossum 80c2a1674e American spelling in doc string. 1997-06-02 14:43:07 +00:00
Guido van Rossum e3f5b9c8d1 Added dict.absorb() and dict.copy(). 1997-05-28 19:15:28 +00:00
Guido van Rossum c8b6df9004 PyObject_Compare can raise an exception now. 1997-05-23 00:06:51 +00:00
Guido van Rossum 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.
 1997-05-23 00:01:41 +00:00
Guido van Rossum 27a60b147c PyFile_WriteString now returns an error indicator instead of calling 
PyErr_Clear().
 1997-05-22 22:25:11 +00:00
Guido van Rossum e9eec54798 Fix typo in error checking spotted by Just... 1997-05-22 14:02:25 +00:00
Guido van Rossum a9040ec5d9 Renamed a local variable from 'PyCFunction' (which is also a typedef 
in methodobject.h) to 'func'.  /bin/cc on SunOS 4.x didn't grok this.
 1997-05-20 22:09:08 +00:00
Guido van Rossum 037b2205e8 Moved PyObject_{Get,Set}Attr to object.c. 
Fixed two 'return NULL' that should be 'return -1'.
 1997-05-20 18:35:19 +00:00
Guido van Rossum 98ff96adba Moved PyObject_{Get,Set}Attr here (from dictobject) and add PyObject_HasAttr. 1997-05-20 18:34:44 +00:00
Guido van Rossum 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.
 1997-05-20 18:21:34 +00:00
Guido van Rossum 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.
 1997-05-16 14:23:33 +00:00
Guido van Rossum d0c87ee6c4 Oops, another forgotten renaming: varobject -> PyVarObject. 1997-05-15 21:31:03 +00:00
Guido van Rossum e61093c218 Fix reversed test for failure in PySequence_List() and PySequence_Tuple(). 
This broke cPickle.
 1997-05-14 18:43:29 +00:00
Guido van Rossum 9637432265 Renamed mappingobject.c to dictobject.c. 1997-05-13 21:05:38 +00:00
Guido van Rossum a9e7a81137 Renamed from mappingobject.c to dictobject.c. 
(Sorry Jack, all your projects will have to be changed again. :-( )
 1997-05-13 21:02:11 +00:00
Guido van Rossum 93ad0df06c Faster floating point allocator, same idea as the int allocator. 
By Aaron Watters.
 1997-05-13 21:00:42 +00:00
Guido van Rossum 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
Guido van Rossum 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.
 1997-05-09 22:27:31 +00:00
Guido van Rossum 0add15f6a5 removed last #ifdef SUPPORT_OBSOLETE_ACCESS bits. 1997-05-09 01:07:15 +00:00
Guido van Rossum b819914263 Fix by Mark Hammond to enable truncate() on Windows. 1997-05-06 15:23:24 +00:00
Guido van Rossum fdf95dd525 Checkin of Jack's buffer mods. 
Not really checked, but didn't fail any tests either...
 1997-05-05 22:15:02 +00:00
Guido van Rossum a027efa5bf Massive changes for separate thread state management. 
All per-thread globals are moved into a struct which is manipulated
separately.
 1997-05-05 20:56:21 +00:00
Guido van Rossum c0b618a2cc Quickly renamed the last directory. 1997-05-02 03:12:38 +00:00
Guido van Rossum 1875247549 Quickly renamed. 1997-04-29 14:49:28 +00:00
Guido van Rossum 3648884490 (Jack:) Align mapping entries to 4-words if USE_CACHE_ALIGNED is defined. 1997-04-11 19:14:07 +00:00
Guido van Rossum 2095d24842 Tweaks to keep the Microsoft compiler quiet. 1997-04-09 19:41:24 +00:00
Guido van Rossum 8017767420 Remove unused variable. 1997-04-09 18:22:28 +00:00
Guido van Rossum 6191551ad6 Remove a redundant XINCREF(value). This caused the reference count of 
all locals to be upped by one when `from <module> import <whatever>'
was executed.
 1997-04-03 18:31:43 +00:00
Guido van Rossum 4669fb474b Several fixes reported by jim F. 1997-04-02 05:31:09 +00:00
Guido van Rossum c054d70aee Get rid of .conj pseudo data attribute for complex numbers. 
Add __members__ attribute.
 1997-04-01 03:12:33 +00:00
Guido van Rossum fb8f1cadb2 Add clear() method to dictionary objects. 1997-03-21 21:55:12 +00:00
Guido van Rossum f2e499b1d7 New long_lshift, without restriction on size of shift count, by Tim Peters. 
This makes it possible to write 1L<<1000000, memory permitting.
 1997-03-16 00:37:59 +00:00
Guido van Rossum 45b83915f8 New form of PyFPE_END_PROTECT macro. 1997-03-14 04:32:50 +00:00
Guido van Rossum 19700b6a98 Add casts to CMPERROR macro to silence SunPro compiler warnings about 
integer overflow in << operator.
