[issue5730] setdefault speedup

[Martin v. Löwis]

Martin v. Löwis  added the comment:

> The missing key reports the default object, but doesn't set that key  
> or value object in the dict.

That's just not true. Re-read the line in the doc string where it
puts the default value into the dict, under the key being accessed.

> For example, to represent a graph structure, it is helpful to use a  
> dict-of-dicts.

No problem:

py> from collections import defaultdict
py> weights=defaultdict(dict)
py> weights['a']['b']=17
py> weights['a']['c']=5
py> weights['a']
{'c': 5, 'b': 17}

See? It remembered the default value, and the value for the 'a'
key got changed and can now be modified. The whole point of defaultdict
was to replace setdefault, so that setdefault can eventually be
eliminated, see

http://mail.python.org/pipermail/python-dev/2006-February/061169.html
http://mail.python.org/pipermail/python-dev/2006-February/061261.html

Apparently, the plan for removing setdefault is now forgotten. Perhaps
this would be a good time to revive it, with a proper deprecation
procedure. If it is to be removed, I'm -1 for "fixing" anything about
it.

[issue5741] SafeConfigParser incorrectly detects lone percent signs

[Márcio Faustino]

Márcio Faustino  added the comment:

Shouldn't the "replace('%%', '')" take place before 
"_interpvar_re.sub"? For example, the value "%%(test)s" should be 
accepted as valid but it isn't because "_interpvar_re" has already 
changed it to "%".

[issue5736] Add the iterator protocol to dbm modules

[Martin v. Löwis]

I agree with Skip that using a static variable is not appropriate. The

[issue5736] Add the iterator protocol to dbm modules

[Akira Kitada]

Akira Kitada  added the comment:

Yes, using a static variable there is wrong and
actually I'm now working on "dbm_iterobject" just as Martin suggested.

dbm iterator should behave just like one in dict.
I think I can use Objects/dictobject.c as a good example for this.

Attached is minimal tests for dbm iterator.

[issue5747] knowing the parent command

[Tarek Ziadé]

New submission from Tarek Ziadé :

Right now there's no way in a command to know that it was launched as a
subcommand from another command.

For instance every install_* command knows explicitely that it is
launched as a subcommand of 'install' and takes back its options in
finalize_options() using set_undefined_options().

For commands that might be used as subcommands of several commands, we
need to pass the name of the parent command to finalize_options() so 
we can call set_undefined_options() without knowing explicitely the name
of the parent command.

This will be done by adding an optional parameter called
'parent_command', to run_command(), then to ensure_finalized() and to
finalized_options().

The first use case of this will be the check command, that will be used
by "register" and "sdist".

This change will be backward compatible with the existing commands and
ths new parameter optional

[issue5746] socketserver problem upon disconnection (undefined member)

[Victor Godoy Poluceno]

Victor Godoy Poluceno  added the comment:

Can you provide a small example of this error?

This problem seems only occurer when a subclass of
socketserver.StreamRequestHandler provide a blank method "setup".

In your log error:

>> AttributeError: 'RequestHandler' object has no attribute 'wfile'

The class 'RequestHandler' is a subclass of
socketserver.StreamRequestHandler?

[issue5746] socketserver problem upon disconnection (undefined member)

[Eric Blond]

Eric Blond  added the comment:

That's it actually.

I forgot to call base class' setup() method when I redefined it in my 
subclass. When I properly call StreamRequestHandler.setup() on my 
derived class' setup(), everything works fine.

I'm not a socketserver specialist, but I would have expected 
StreamRequestHandler to derive from RequestHandler and not the other 
way round, although it makes little difference to me as a user's point 
of view.

Thanks a lot for pointing my mistake!

Cheers,
-Eric

[issue3440] Starting any program as a subprocess fails when subprocess.Popen has env argument

[R. David Murray]

R. David Murray  added the comment:

As I said, if you replace the environment it is your responsibility to
supply a working environment.  I've attached a doc patch that adds a
warning about this with the information that a valid SystemRoot is
needed to run a side-by-side assembly (whatever that is :).

If you think the doc patch is accurate I will commit it (unless Georg
objects).

[issue5748] Objects/bytesobject.c should include stringdefs.h, instead of defining its own macros

[Eric Smith]

New submission from Eric Smith :

All of the macros it defines around line 565 should either already be in
stringdefs.h, or they should be added there.

The same issue exists in Objects/bytearrayobject.c. I haven't looked in
2.7, but I assume the same problem exists there.

You are welcome.  If you want something to happen, though,
you'll have to get support from the community and submit
a patch.

Is there some way in which sys.stdout.flush() is not equivalent to "an
fflush implementation that will enable print()'s buffers to be flushed"?

> Maybe I should raise another "fflush() support required" bug ?

If it's a real issue, yes.  But I don't think it is.

[issue5749] Allow bin() to have an optional "Total Bits" argument.

[MechPaul]

New submission from MechPaul :

As it stands right now, bin() only shows the minimum number of bits to
display the number, however I think having a "Total Bits" argument would
be very, very useful for bin().

bin(value, [Total bits to display])

"Total bits to display" is an integer.

Here's how it should work:

>>> bin(0x7F)
'0b111'
>>> #Note, there are seven 1's there to represent the value 127
>>> bin(0x7F, 8)
'0b0111'
>>> #Now there are eight bits displayed.
>>> bin(0xFF, 16)
'0b'
>>> #This makes it a lot easier to read and compare binary numbers!

[issue5730] setdefault speedup

[Dan Schult]

Dan Schult  added the comment:

Thank you... I stand corrected
That's actually very helpful!

Of course using defdict makes the default assignment take two hashes,  
two lookups, an attribute/function lookup (__missing__) and the extra  
function call, plus doesn't allow arguments to the object factory...  
but it means that there is a hook into the dict API that allows us to  
create something when GetItem/subscript gives a KeyError...  I  
understand much more what I should be doing and where to look for it.

Thanks very much!

I still would prefer that the C-API allow PyDict_SetItem to be called  
without a hash or lookup.  Maybe a method called PyDict_SetEntry().   
But I haven't really looked at it, don't have a patch and am not sure  
if it is worth it.  I am willing to spend time doing looking into  
that kind of thing if you think that might be helpful.  Otherwise I  
will put it on my list of fun-projects-for-hazy-summer-weekends and  
get to it when I get to it.

Dan
