Martin v. Löwis ac93bc2501 When decoding UTF-16, don't assume that the buffer is in native endianness 
when checking surrogates.
 2001-06-26 22:43:40 +00:00
Tim Peters 208efe5640 Windows build broke from recent Unicode changes -- need to #define 
SIZEOF_SHORT by hand here.
Also added dynamic check that SIZEOF_SHORT is correct for the platform (in
_testcapimodule).
 2001-06-26 22:40:47 +00:00
Tim Peters e77f2e2798 gen_getattr: make the gi_running and gi_frame members discoverable (but 
not writable -- too dangerous!) from Python code.
 2001-06-26 22:24:51 +00:00
Martin v. Löwis 0ba70cc3c8 Support using UCS-4 as the Py_UNICODE type: 
Add configure option --enable-unicode.
Add config.h macros Py_USING_UNICODE, PY_UNICODE_TYPE, Py_UNICODE_SIZE,
                    SIZEOF_WCHAR_T.
Define Py_UCS2.
Encode and decode large UTF-8 characters into single Py_UNICODE values
for wide Unicode types; likewise for UTF-16.
Remove test whether sizeof Py_UNICODE is two.

Jack Jansen ff1cc902fe Added a Parser_OSX class that can parse new-style (C-only) headers, 
such as the Core Foundation ones.
 2001-06-26 21:53:25 +00:00
Jack Jansen f4b9fb719a Added CF module build and project generation (carbon only). 2001-06-26 21:52:08 +00:00
Jack Jansen 686f9c344c First small step towards bgen-generated CoreFoundation. there is hardly any real functionality yet, but method chains seem to work, and so do Retain/Release semantics. 2001-06-26 21:51:18 +00:00
Tim Peters d8e1c9e177 Add "gi_" (generator-iterator) prefix to names of genobject members. 
Makes it much easier to find references via dumb editor search (former
"frame" in particular was near-hopeless).
 2001-06-26 20:58:58 +00:00
Fredrik Lundh ee13dba1aa more unicode tweaks: fix unicodectype for sizeof(Py_UNICODE) > 
sizeof(int)
 2001-06-26 20:36:12 +00:00
Barry Warsaw e9218a1a8e Remove the restriction on a mapping's .update() method. 2001-06-26 20:32:59 +00:00
Barry Warsaw 51acc8d363 Add an item about the extension to {}.update() to allow generic 
mapping objects as an argument.
 2001-06-26 20:12:50 +00:00
Barry Warsaw 41775385df Add a bunch of tests for extended dict.update() where the argument is 
a non-dictionary mapping object.  Include tests for several expected
failure modes.
 2001-06-26 20:09:28 +00:00
Barry Warsaw 66a0d1d9b9 dict_update(): Generalize this method so {}.update() accepts any 
"mapping" object, specifically one that supports PyMapping_Keys() and
PyObject_GetItem().  This allows you to say e.g. {}.update(UserDict())

We keep the special case for concrete dict objects, although that
seems moderately questionable.  OTOH, the code exists and works, so
why change that?

.update()'s docstring already claims that D.update(E) implies calling
E.keys() so it's appropriate not to transform AttributeErrors in
PyMapping_Keys() to TypeErrors.

Patch eyeballed by Tim.
 2001-06-26 20:08:32 +00:00
Fredrik Lundh 0dcf67e56d more unicode tweaks: make unichr(0xdddddddd) behave like u"\Udddddddd" 
wrt surrogates.  (this extends the valid range from 65535 to 1114111)
 2001-06-26 20:01:56 +00:00
Fredrik Lundh 5b97935604 experimental UCS-4 support: don't assume that MS_WIN32 implies 
HAVE_USABLE_WCHAR_T
 2001-06-26 17:46:10 +00:00
Fredrik Lundh 1294ad0c59 experimental UCS-4 support: added USE_UCS4_STORAGE define to 
unicodeobject.h, which forces sizeof(Py_UNICODE) == sizeof(Py_UCS4).
(this may be good enough for platforms that doesn't have a 16-bit
type.  the UTF-16 codecs don't work, though)
 2001-06-26 17:17:07 +00:00
Fredrik Lundh 45714e9ecb experimental UCS-4 support: made compare a bit more robust, in case 
sizeof(Py_UNICODE) >= sizeof(long).  also changed surrogate expansion
to work if sizeof(Py_UNICODE) > 2.
 2001-06-26 16:39:36 +00:00
Fredrik Lundh 3083163dc1 experimental UCS-4 support: don't assume that MS_WIN32 implies 
HAVE_USABLE_WCHAR_T

Jack Jansen ba18673045 Added a note about recompiling OSAm before distributing. 2001-06-26 08:06:59 +00:00
Just van Rossum 639a740e50 Fixed typo in doc string. 2001-06-26 06:57:12 +00:00
Just van Rossum 0297dca941 Fixed bug that prevented shared libs that are submodules of a 
package to be loaded from a PYD resource.
 2001-06-26 06:54:33 +00:00
Tim Peters b6c3ceae79 SF bug #436207: "if 0: yield x" is ignored. 
Not anymore <wink>.  Pure hack.  Doesn't fix any other "if 0:" glitches.
 2001-06-26 03:36:28 +00:00
Tim Peters 3e7b1a04a0 Teach the types module about generators. Thanks to James Althoff on the 
Iterators list for bringing it up!
 2001-06-25 19:46:25 +00:00
Just van Rossum ae1f65ff82 Return self.trace_dispatch from dispatch_return() to enable stepping through generators. (An alternative would be to create a new "yield" debugger event, but that involves many more changes, and might break Bdb subclasses.) 2001-06-25 18:01:24 +00:00
Fred Drake b037d33245 Updated link to zlib's home page. 2001-06-25 15:30:13 +00:00

Add a temporary driver to help track down remaining leak(s).

Tim Peters fee69d0313 Changed some comments. Removed the caution about clearing globs, since 
clearing a shallow copy _run_examples() makes itself can't hurt anything.
 2001-06-24 20:24:16 +00:00
Tim Peters d4ad59e1eb Clear the copy of the globs dict after running examples. This helps to 
break cycles, which are a special problem when running generator tests
that provoke exceptions by invoking the .next() method of a named
generator-iterator:  then the iterator is named in globs, and the
iterator's frame gets a tracekback object pointing back to globs, and
gc doesn't chase these types so the cycle leaks.

Also changed _run_examples() to make a copy of globs itself, so its
callers (direct and indirect) don't have to (and changed the callers
to stop making their own copies); *that* much is a change I've been
meaning to make for a long time (it's more robust the new way).

Here's a way to provoke the symptom without doctest; it leaks at a
prodigious rate; if the last two "source" lines are replaced with
    g().next()
the iterator isn't named and then there's no leak:

source = """\
def g():
    yield 1/0

k = g()
k.next()
"""

code = compile(source, "<source>", "exec")

def f(globs):
    try:
        exec code in globs
    except ZeroDivisionError:
        pass

while 1:
    f(globals().copy())

After this change, running test_generators in an infinite loop still leaks,
but reduced from a flood to a trickle.
 2001-06-24 20:02:47 +00:00
Tim Peters 77f2d504c3 doctest systematically leaked memory when handling an exception in an 
example (an obvious trackback cycle).  Repaired.
Bugfix candidate.
 2001-06-24 18:59:01 +00:00
Tim Peters b2bc6a93df Added a "generate k-combinations of a list" example posted to c.l.py. 2001-06-24 10:14:27 +00:00
Tim Peters ea2e97a08a New tests to provoke SyntaxErrors unique to generators. Minor fiddling 
of other tests.
 2001-06-24 07:10:02 +00:00
Tim Peters 08bba953ea doctest doesn't handle intentional SyntaxError exceptions gracefully, 
because it picks up the first line of traceback.format_exception_only()
instead of the last line.  Pick up the last line instead!
 2001-06-24 06:46:58 +00:00
Tim Peters ee30927b45 Another variant of the 2-3-5 test, mixing generators with a LazyList class. 
Good news:  Some of this stuff is pretty sophisticated (read nuts), and
I haven't bumped into a bug yet.
Bad news:  If I run the doctest in an infinite loop, memory is clearly
leaking.
 2001-06-24 05:47:06 +00:00
Tim Peters 7e82b9cc6b Pure brute-force hackery to allow Python to build on Windows again, 
because I need to make progress and don't have time now to think about
whatever it is the new code is trying to accomplish.
 2001-06-24 05:08:52 +00:00
Tim Peters b9e9ff1288 More tests. 2001-06-24 03:44:52 +00:00
Tim Peters 0f9da0acde Add a recursive Sieve of Eratosthenes prime generator. Not practical, 
but it's a heck of a good generator exerciser (think about it <wink>).
 2001-06-23 21:01:47 +00:00
Tim Peters 6ba5f79674 Add all the examples from PEP 255, and a few email examples. 2001-06-23 20:45:43 +00:00
Tim Peters 1def351b45 New std test for generators, initially populated with doctests NeilS put 
together.
