[issue1542677] IDLE shell gives different len() of unicode strings compared to Python shell
Santiago Gala sg...@apache.org added the comment:
Updating the components as the error surfaces in the compile builtin.
the compile builtin works when given unicode, but fails when using a
utf8 (local input encoding) string.
Rather than adding a coding string to compile, my guess is that
compile should be fixed or fed a unicode string. See the effects on the
shell:
print len('à')
2
print len(u'à')
1
exec compile(print len('à'),'test', 'single')
2
exec compile(print len(u'à'),'test', 'single')
2
exec compile(print len('à').decode(utf8),'test', 'single')
2
exec compile(print len(u'à').decode(utf8),'test', 'single')
1
So the error disappears when the string fed to exec compile is properly
decoded to unicode.
In idlelib there is an attempt to encode the input to
IOBindings.encoding, but IOBindings.encoding is broken here, as
locale.nl_langinfo(locale.CODESET) gives 'ANSI_X3.4-1968', which looks
up as 'ascii', while locale.getpreferredencoding() gives 'UTF-8' (as it
should).
If I comment the whole attempt, idle works (for this test, not fully
tested):

[issue5736] Add the iterator protocol to dbm modules
Akira Kitada akit...@gmail.com added the comment:
Here's another patch which addsd iter to dbm and gdbm.
Note that dbm and gdbm C API is a little different.
gdbm_nextkey requires key for its argument, dbm_nextkey don't.
So I had to use for gdbm an static variable that points to the current
position.
Now iterator in gdbm and dbm works differently.
import dbm
d = dbm.open('foo', 'n')
d['k1'] = 'v1';d['k2'] = 'v2';
for i in d: print i; break
...
k1
for i in d: print i
...
k2
for i in d: print i

gd = gdbm.open('foo.gdbm', 'n')

[issue1542677] IDLE shell gives different len() of unicode strings compared to Python shell
Naoki INADA songofaca...@gmail.com added the comment:
utf-8 is not locale encoding.
f = open('á.txt')
If this line compiled into utf-8 and locale encoding is not utf-8, can't
open 'á.txt'.
IMHO, in case of Python 2.x, correct approach is fix IOBindings.encoding
and compile() with pep0263.

[issue5741] SafeConfigParser incorrectly detects lone percent signs
New submission from Márcio Faustino m.faust...@gmail.com:
The SafeConfigParser class incorrectly detects lone percent signs,
for example, it doesn't accept 100%% as a valid value. The cause of
this is the _badpercent_re regular expression:
- The first alternative %[^%] fails with the string %%_, because it
matches %_.
- The second alternative %$ fails with the string %%, because it
matches %.

[issue5730] setdefault speedup
Dan Schult dsch...@colgate.edu added the comment: On Apr 11, 2009, at 8:15 AM, Martin v. Löwis rep...@bugs.python.org@psf.upfronthosting.co.za @psf.upfronthosting.co.za wrote: Martin v. Löwis mar...@v.loewis.de added the comment: By the way, defaultdict is NOT like setdefault--it is like get(). Missing entries do no get set. Why do you say that? __missing__(...) __missing__(key) # Called by __getitem__ for missing key; pseudo-code: if self.default_factory is None: raise KeyError((key,)) self[key] = value = self.default_factory() return value In all cases of setdefault that I know of, replacing this with a defaultdict would be appropriate. The only case where it wouldn't work is if the default value depends on the key. The missing key reports the default object, but doesn't set that key or value object in the dict. So you cannot then call up that object and do something that depends on the key. So the default value may not depend on the key but still need to be different for each key due to later changes. For example, to represent a graph structure, it is helpful to use a dict-of-dicts. The first time a node is looked up you want to add it as a key in the graph dict with an empty nbr dict as the value. the nbr dict is keyed by neighbor to the edge weight/object. So the default object is always a fresh nbr dict... but what gets added to that nbr dict depends on which node it is. I can come up with examples for lists too... But as you pointed out before, using a list or dict in setdefault requires creating the object before the call anyway... I'm beginning to question whether setdefault should ever be used... Still comes back to--why have it there inefficiently. Besides I'm still interested in being able to do this sort of thing at least through the C-API... Raymond Hettinger rhettin...@users.sourceforge.net added the comment: from my perspective creating an internal SetItem adds another function handling the data structure just as setdefault would Incorrect comparison. Your in-lining manipulated the ep structure directly (not a good thing). In contrast, adding an alternative _PyDict_SetItemWithHash uses the insertdict() function, fully isolating itself of from the table implementation. The whole purpose of having insertdict() and lookdict() is to isolate the data structure internals from all externally visible functions. Good... I am understanding better what you mean by handling the data structure. I agree that lookdict, insertdict and resizedict should be the three that change the data structure. But the way those 3 are currently written, you can't change an entry without looking it up. insertdict_clean almost does it, but it assumes there aren't any dummy entries. The double call to a very simple user defined __hash__ adds .07 to call that takes on .05 with the double call to builtin object hash. So, we could save half of the the .07 just by elimating the double call to __hash__. With more complex hash functions the overall speedup is huge (essentially cutting the total work almost in half). This is a good example because it shows how the hash can matter. I think there are similar examples where the lookup is most of the time of dict access. I don't know enough about what causes collisions and how dicts are optimized to quickly come up with such an example. But such an example must exist or Tim Peters wouldn't have spent so much effort optimizing lookup besides his comments at the top of lookup suggest that we do exactly what I am suggesting to do. Get the entry from lookup and then the caller can (if it wishes) add the key, value pair to the returned PyDictEntry*. Presently there is no way to do this with C-API except to write my own data structure manipulation. Wouldn't it be better to encapsulate this in the C-API in a standard way instead of having everybody writing their own C-extension doing setdefault the right way? (ok..ok.. everybody here refers to probably one person (me)... but others have thought of it. I've even seen the double lookup as a justification for never using setdefault) I'll look for an example that has lots of collisions. Maybe that would help justify a lookup-less insertdict.

[issue3440] Starting any program as a subprocess fails when subprocess.Popen has env argument
Lenard Lindstrom le...@telus.net added the comment:
notepad.exe forms a side-by-side assembly with COMCTL32.DLL. So
SystemRoot must be included in the environment. The following example
works with Python 2.5.2 on Windows XP.
===
import struct, subprocess
import os
command = 'C:\\WINDOWS\\NOTEPAD.EXE'
env = {'FOO': 'bar', 'SystemRoot': os.environ['SystemRoot']}
p = subprocess.Popen(command, env=env)
p.wait()
err = struct.unpack('I', struct.pack('i', p.returncode))[0]
print '%x (%d)'%(err, err)
===
I would suggest Popen adds SystemRoot to env if it is not present.
