Fred Drake 017778332f Extend some comments on the order of values in the returns from
dict.items/keys/values/iteritems/iterkeys/itervalues().

Guido van Rossum 45ec02aed1 SF patch 576101, by Oren Tirosh: alternative implementation of
interning.  I modified Oren's patch significantly, but the basic idea
and most of the implementation is unchanged.  Interned strings created
with PyString_InternInPlace() are now mortal, and you must keep a
reference to the resulting string around; use the new function
PyString_InternImmortal() to create immortal interned strings.

Guido van Rossum d8dbf847b6 Add a warning comment to the LOAD_GLOBAL inline code. 2002-08-19 21:17:53 +00:00
Guido van Rossum 3a4dfc87e6 Another ugly inlining hack, expanding the two PyDict_GetItem() calls
in LOAD_GLOBAL.  Besides saving a C function call, it saves checks
whether f_globals and f_builtins are dicts, and extracting and testing
the string object's hash code is done only once.  We bail out of the
inlining if the name is not exactly a string, or when its hash is -1;
because of interning, neither should ever happen.  I believe interning
guarantees that the hash code is set, and I believe that the 'names'
tuple of a code object always contains interned strings, but I'm not
assuming that -- I'm simply testing hash != -1.

On my home machine, this makes a pystone variant with new-style
classes and slots run at the same speed as classic pystone!  (With
new-style classes but without slots, it is still a lot slower.)

Guido van Rossum e3a8e7ed1d Call me anal, but there was a particular phrase that was speading to
comments everywhere that bugged me: /* Foo is inlined */ instead of
/* Inline Foo */.  Somehow the "is inlined" phrase always confused me
for half a second (thinking, "No it isn't" until I added the missing
"here").  The new phrase is hopefully unambiguous.

Guido van Rossum 056fbf422d Another modest speedup in PyObject_GenericGetAttr(): inline the call
to _PyType_Lookup().
2002-08-19 19:22:50 +00:00
Guido van Rossum 492b46f29e Make PyDescr_IsData() a macro. It's too simple to be a function.
Should save 4% on slot lookups.

Michael W. Hudson 69734a5272 Check in my ultra-shortlived patch #597220.
Move some debugging checks inside Py_DEBUG.

They were causing cache misses according to cachegrind.
2002-08-19 16:54:08 +00:00
Guido van Rossum c66ff4441e Inline call to _PyObject_GetDictPtr() in PyObject_GenericGetAttr().
This causes a modest speedup.

Guido van Rossum 0b650d7565 Fix typo in __slots__ of ImmutableSet. 2002-08-19 16:29:58 +00:00
Guido van Rossum d8ab35c933 News about sets. (There's no documentation; if someone wants to
convert the doc strings to LaTeX, be my guest.)

Guido van Rossum d6cf3af8f7 Set classes and their unit tests, from sandbox. 2002-08-19 16:19:15 +00:00
Guido van Rossum c588e9041a Simple but important optimization for descr_check(): instead of the
expensive and overly general PyObject_IsInstance(), call
PyObject_TypeCheck() which is a macro that often avoids a call, and if
it does make a call, calls the much more efficient PyType_IsSubtype().
This saved 6% on a benchmark for slot lookups.

Raymond Hettinger f2f2a2c130 Fix spelling errors and note the addition of operator.pow() 2002-08-19 14:25:03 +00:00
Jack Jansen 0281512b87 Merged the MacPython thanks list into the general acknowledgements.
There's really no point in a separate list of thank-you notes.
2002-08-19 13:17:39 +00:00
Raymond Hettinger 5959c559df Added __pow__(a,b) to the operator module. Completes the pattern of
all operators having a counterpart in the operator module.

Closes SF bug #577513.

Tim Peters 7dca21e59f SF bug 595919: popenN return only text mode pipes
popen2() and popen3() created text-mode pipes even when binary mode
was asked for.  This was specific to Windows.

Jack Jansen 58ba80a6a6 Refuse to run if the last bit of the destination path contains a # character.
This is a silly workaround for a rather serious bug in MacOSX: if you take
a long filename and convert it to an FSSpec the fsspec gets a magic
cooky (containing a #, indeed). If you then massage the extension of this
fsspec and convert back to a pathname you may end up referring to the
same file. This could destroy your sourcefile. The problem only occcurs
in MacPython-OS9, not MacPython-OSX (I think).

Closes bug #505562.

Raymond Hettinger f2e45dd9dd Modify splituser() method to allow an @ in the userinfo field.
Jeremy reported that this is not allowed by RFC 2396; however,
other tools support unescaped @'s so we should also.

Apply SF patch 596581 closing bug 581529.

Andrew MacIntyre 1d0eeec279 OS/2 EMX behaves like Windows where file permissions are concerned 2002-08-18 06:47:19 +00:00
Andrew MacIntyre 1adbcebbec update contact info 2002-08-18 06:32:46 +00:00
Andrew MacIntyre 1994c7f1cf Prep for 2.3:
- update DLL version number
 - add files required for 2.3 (no changes to modules though)
 - restructure build of pgen.exe

NOTE:  As I don't have the VACPP compiler, these changes are untested.
Apart from slightly re-ordering some file lists, and matching file name
casing, I believe these changes are the minimum necessary to build 2.3
with VACPP.

Andrew MacIntyre ffcf899554 make port notes current 2002-08-18 06:28:21 +00:00
Andrew MacIntyre 4fffdff2be Build process updates:
- the security fixes to tempfile have lead to test_tempfile wanting
   to create 100 temporary files.  as the EMX default is only 40,
   the number of file handles has been bumped (up to 250).
 - changes to pgen have required restructuring its build support.
2002-08-18 06:26:33 +00:00
Guido van Rossum e888cdc683 Get rid of _once(); inlining it takes less code. :-)
Also, don't call gettempdir() in the default expression for the 'dir'
argument to various functions; use 'dir=None' for the default and
insert 'if dir is None: dir = gettemptir()' in the bodies.  That way
the work done by gettempdir is postponed until needed.
2002-08-17 14:50:24 +00:00
Guido van Rossum 787410680b Patch by Zack W to make test_noinherit() more robust: spawn a Python
subprocess that does the right checks.  This now works on Windows as
well.

Neal Norwitz b898d9fc9a Get this to compile again if Py_USING_UNICODE is not defined.
com_error() is static in Python/compile.c.

Neal Norwitz 68ee0128a2 Drop the number of test files to 100 for all the tests 2002-08-16 19:28:59 +00:00
Jeremy Hylton 192690e2d2 Inline fast_cfunction() in new call_function().
Also, don't handle METH_OLDARGS on the fast path.  All the interesting
builtins have been converted to use METH_NOARGS, METH_O, or
METH_VARARGS.

Result is another 1-2% speedup.  If I can cobble together 10 of these,
it might make a difference.
2002-08-16 18:36:11 +00:00
Guido van Rossum aca139d17d Remove the outdated PLAN.txt file. 2002-08-16 18:32:53 +00:00
Jeremy Hylton e8c0432403 Move body of CALL_FUNCTION opcode into helper function.
This makes the code much easier to ready, because it is at a sane
indentation level.  On my box this shows a 1-2% speedup, which means
nothing, except that I'm not going to worry about the performance
effects of the change.

Guido van Rossum 84b2bed435 Squash a few calls to the hideously expensive PyObject_CallObject(o,a)
-- replace then with slightly faster PyObject_Call(o,a,NULL).  (The
difference is that the latter requires a to be a tuple; the former
allows other values and wraps them in a tuple if necessary; it
involves two more levels of C function calls to accomplish all that.)
2002-08-16 17:01:09 +00:00
Guido van Rossum c13f724af0 Streamline the fast track for CFunction calls a bit more: there was
nothing special done if keyword arguments were present, so test for
that earlier and fall through to the normal case if there are any.
This ought to slow down CFunction calls with keyword args, but I don't
care; it's a tiny (1%) improvement for pystone.

Jack Jansen 49931887d7 Regenerated with PyDoc_STR() around docstrings. 2002-08-16 09:09:31 +00:00
Jack Jansen 44b99e0a1f iUse PyDoc_STR() around docstrings. 2002-08-16 09:07:42 +00:00
Guido van Rossum c7903a13d2 A nice little speed-up for filter():
- Use PyObject_Call() instead of PyEval_CallObject(), saves several
  layers of calls and checks.

- Pre-allocate the argument tuple rather than calling Py_BuildValue()
  each time round the loop.

- For filter(None, seq), avoid an INCREF and a DECREF.
2002-08-16 07:04:56 +00:00
Guido van Rossum 8e829200b1 Fix SF bug 595838 -- buffer in type_new() should not be static. Moved
to inner scope, too.

Tim Peters 9146f27b77 SF bug 594996: OverflowError in random.randrange
Loosened the acceptable 'start' and 'stop' arguments so that any
Python (bounded) ints can be used.  So, e.g., randrange(-sys.maxint-1,
sys.maxint) no longer blows up.
2002-08-16 03:41:39 +00:00
Tim Peters 012c0a393a Newly-relaxed limits on random.randrange(). Also added some info about
Karatsuba's better cache behavior with extremely large multiplicands.
2002-08-16 03:40:07 +00:00
Guido van Rossum f808b891d6 Mention warnings about defining None. 2002-08-16 03:38:10 +00:00
Guido van Rossum b7164621fa Add warnings for arguments named None. All set. (I could add a
warning for 'global None', but that's either accompanied by an
assignment to None, which will trigger a warning, or not, in which
case it's harmless. :-)
2002-08-16 02:48:11 +00:00
Tim Peters 80703c8930 check_events(): This was failing under -O, due to not expecting any
LINE events when not __debug__.  But we get them anyway under -O now,
so just stop special-casing non-__debug__ mode.
2002-08-16 02:27:15 +00:00
Guido van Rossum 63dd79ac04 Add warning for None used as keyword argument name in function call.
Still to do: function definition arguments (including *None and
**None).
2002-08-16 02:24:56 +00:00
Guido van Rossum 3ac99d4910 Add warnings for assignment or deletion of variables and attributes
named 'None'.  Still to do: function definition parameter lists, and
function call keyword arguments.
2002-08-16 02:13:49 +00:00
Guido van Rossum b081e0c74c Minor cleanup of parsename() and parsestr(): the 'struct compiling *'
argument should be called 'c', like everywhere else.  Renamed a
complex variable 'c' to 'z' and moved it inside the only scope where
it's used.
2002-08-16 01:57:32 +00:00
Barry Warsaw 0a51b58e6b base64.decodestring('') should return '' instead of raising an
exception.  The bug fix for SF #430849 wasn't quite right.  This
closes SF bug #595671.  I'll backport this to Python 2.2.
2002-08-15 22:14:24 +00:00
Jack Jansen 7ca993ed37 Fixed the bugs in the constant definitions, and in the code to test
them.
The FutureWarnings are still there, until a way has been found to
say "I know what I'm doing here when I say 0xff000000".
2002-08-15 22:05:58 +00:00
Jack Jansen 87eea88b5a After generating the Python file with definitions try to run it, so
we catch errors during the build process in stead of later during runtime.
2002-08-15 21:48:16 +00:00
Jack Jansen 81204152d4 Try to cater for a source tree checked out with MacCVS in stead of
unix cvs. In this case the resource files are actual resource files
in stead of AppleSingle encoded files.
