TreePyO 0.1 - Object Hierarcy Tree Navigator for Python - Initial Release
I'd like to announce the initial release of TreePyO: Object Hierarcy Tree Navigator for Python https://github.com/imrn/TreePyO GENERAL === TreePyO enables visual navigation of full object hierarcy within a Python runtime. It is ideal for grasping the internals an application. Objects, members, classes, functions, modules, lists, dicts, etc; namely, any object hierarcy can be navigated as they are alive. SCREENSHOT == https://github.com/imrn/TreePyO/blob/master/treepyo.jpg LICENSE === TreePyO is released under the terms of MIT license. Please see LICENSE.txt REQUIREMENTS - Python = 3.2 - GObject Introspection (GIR) - Python GIR bindings - GTK3 On Debian or Ubuntu systems issue the following command. (Adjust versions for current releases if needed):: apt-get install python3-gi gir1.2-gtk-3.0 USAGE DETAILS === - For a demo, just run the file 'treepyo.py'. Object tree will appear with two root nodes: 1) '__main__' module 2) the window itself. Browsing the tree is trivial. However, familarity with Python internals is recommended. Please see: http://docs.python.org/3.2/reference/datamodel.html - Find as you type search is available for expanded nodes. - Collapsing and reexpanding an object node refreshes the children. - TreePyO class inherits from Gtk.ScrolledWindow. You can use it like any other widget in your projects. TO-DOs PROGRESS (%) = - Decide on the standard view of a Python Environment. (40%) - A primitive context menu is provided. Decide on its use for standard view. (10%) - Compile use cases as a widget. Provide patterns for customizing the tree, context menu and actions. (0%) Forks are welcome..

I don't see where my comments suggested that this group is only for serious programmers. I simply believe that the UNIX platform, in whatever form, is better placed and designed for all sorts of computing and engineering projects. The history of UNIX speaks for itself. Many Universities that offer respected and credible science based degree programmes, namely engineering and computing programmes, strongly encourage students to become competent with UNIX systems. Windows in my opinion is really for those who use the internet on a casual basis or in a commercial environment where its staff are not necessarily computer literate and therefore need a platform that they can use which doesn't require them to learn more complex techniques and protocols. But, having said that, I'm not against Windows at all. I use it frequently and enjoy using it most of the time. serious is also a matter of opinion. I have some serious programmer friends who maintain, in complete sincerity, that serious programmers should not waste time on slow, script-kiddie languages like Python, but should be developing their skills with serious professional languages like Java, C#, etc. That is a narrow minded approach. different languages serve different purposes and it's down to the developer to use which language she needs to achieve what it is they've set out to do. Sometimes, basic shell scripts can be extremely powerful for certain tasks; other needs will require something different. I certainly wouldn't describe Python as a script-kiddie language. It's extremely powerful and modern. So there ;-P lol Real programmers (can) write in assembler. -- http://mail.python.org/mailman/listinfo/python-list

Google spreadsheets - getting started
I want to mess around with my online Google spreadsheets from my Linux box programmatically. I am TOTALLY confused.

OK, maybe the p12 file is useful after all (?)

OK, the story so far:
import gdata
import gdata.auth
import gdata.gauth
import gdata.docs.service
import OpenSSL.crypto
tokenfile = privatekey.p12
#f = open(tokenfile, 'r')
#blob = f.read()
#f.close()
#if blob:
p12 = OpenSSL.crypto.load_pkcs12(file(tokenfile, 'rb').read(), 'notasecret')
print p12.get_certificate()
#token = gdata.gauth.token_from_blob(p12)
#print token: , token

Actually, for many applications, the space savings may actually be
*costs*, since interning forces Python to hold onto strings even after
they would normally be garbage collected. CPython interns strings that
look like identifiers. It really wouldn't be a good idea for it to
automatically intern every string.
You can make your own intern system with a simple dict:
interned_strings = {}
Then, for every string you care about, do:
s = interned_strings.set_default(s, s)
to ensure you are always working with a single string object for each
unique value. In some applications that will save time at the expense of
space.
And there is no need to write is instead of ==, because string
equality already optimizes the strings are identical case. By using ==,
you don't get into bad habits, you defend against the odd un-interned
string sneaking in, and you still have high speed equality tests.

The bottom line is: __getitem__ must always *PASS* len( seq ) to slice()
each *time* the slice() object is-used. Since this is the case, it would
have been better to have list, itself, have a default member which takes the
raw slice indicies and does the conversion itself. The size would not need
to be duplicated or passed -- memory savings, speed savings...
And then tuple would need to duplicate the same code. As would deque.
And str. And numpy.array, and anything else that can be sliced,
including custom sequence classes.
I don't think that's true. A generic function can be shared among
different objects without being embedded in an external index data
structure to boot!
If *self* were passed to an index conversion function (as would
naturally happen anyway if it were a method), then the method could take
len( self ) without knowing what the object is;
Should the object be sliceable -- the len() will definitely return the
required piece of information.
Numpy arrays are very different internally from lists.
Of course! (Although, lists do allow nested lists.)
I'm not understanding what this is meant to demonstrate. Is MyClass

We could also require the user to explicitly declare when they're
performing arithmetic on variables that might not be floats. Then we
can turn off run-time type checking unless the user explicitly
requests it, all in the name of micro-optimization and explicitness.
:) None of those would help micro-optimization that I can see.
Seriously, whether x is usable as a sequence index is a property of x,
not a property of the sequence.
Yes, but the *LENGTH* of the sequence is a function of the *sequence*.

cost anything. (The source does refer to immortal interned strings,

find it in help(sys.intern) which is the obvious place to look.)
You can make your own intern system with a simple dict:
interned_strings = {}

s = interned_strings.set_default(s, s)
to ensure you are always working with a single string object for each

Doing it manually like this _will_ leak like that, though, unless you
periodically check sys.getrefcount and dispose of unreferenced
entries.

equality already optimizes the strings are identical case. By using ==,
you don't get into bad habits, you defend against the odd un-interned

This one I haven't checked the source for, but ISTR discussions on

unicodeobject.c#l6128
I don't think it does, although I could be wrong, I find reading C to be
quite difficult.
The unicode_compare function compares character by character, true, but
it doesn't get called directly. The public interface is
PyUnicode_Compare, which includes this test before calling
unicode_compare:
/* Shortcut for empty or interned objects */
if (v == u) {
Py_DECREF(u);
Py_DECREF(v);
return 0;
}
result = unicode_compare(u, v);
where v and u are pointers to the unicode object.
So it appears that the test for strings being equal length have been
dropped, but the identity test is still present.
Comparing strings char for char is really not that big a deal though.
Depends on how big the string and where the first difference is.
This has been discussed before: you don't need to compare very many
characters to conclude that strings are unequal (if I remember correctly
you were part of that discussion).
On average. Worst case, you have to look at every character.

There's a shortcut if they're the same. There's no shortcut if they're
both interned and have different pointers, which is a guarantee that
they're distinct strings. They'll still be compared char-for-char
until there's a difference.
But it probably isn't enough of a performance penalty to be concerned
with. It's enough to technically prove the point that 'is' is faster
than '==' and is still safe if both strings are interned; it's not
enough to make 'is' better than '==', except in very specific
situations.

[issue16218] Python launcher does not support unicode characters
Stefan Krah added the comment:
I think this is what went wrong on Windows in the previous test (see
Lib/test/test_cmd_line_script.py:43):
s = '\udcf1\udcea\udcf0\udce8\udcef\udcf2'
f = open(s, w)
f.write(print('%s\\n' % __file__))
f.close()
C:\Users\stefan\pydev\cpythonPCbuild\amd64\python_d.exe ï�
encoding error
So __file__ isn't set correctly, which looks like a bug to me. I'm not sure
whether it should be part of this issue or if we should open a new one.

[issue16218] Python launcher does not support unicode characters
Serhiy Storchaka added the comment:
Andrew, you shod a flea.
1. Now the test skipped on non Cyrillic-compatible locales (such as
en_US.ISO-8859-1).
2. On UTF-8 locale the test does not test the bug (it passed even without the
patch).
Here is a new patch. It should fail on FreeBSD with ASCII locale (because there
is a yet not fixed bug), and I don't know how it will behave on Windows.
Temporary you can explicitly skip the test for such case:
@unittest.skipIf(sys.platform.startswith('freebsd') and
sys.getfilesystemencoding() == 'ascii',
'skip on FreeBSD with ASCII filesystem encoding')

[issue16353] add function to os module for getting path to default shell
Christian Heimes added the comment:
which('sh') isn't correct here. 'which' searches in all PATH environ parts.
However the shell must be looked up in CS_PATH only.
From man sh(1posix):
Applications should note that the standard PATH to the shell cannot be
assumed to be either /bin/sh or /usr/bin/sh, and should be determined by
interrogation of the PATH returned by getconf PATH , ensuring that the
returned pathname is an absolute pathname and not a shell built-in.
'getconf PATH' queries confstr(_CS_PATH).
I suggest that you modify the POSIX part to:
path = os.confstr(CS_PATH)
which('sh', path=path)

[issue16389] re._compiled_typed's lru_cache causes significant degradation of the mako_v2 bench
mike bayer added the comment: in response to ezio, I poked around the source here, since I've never been sure if re.compile() cached its result or not. It seems to be the case in 2.7 and 3.2 also - 2.7 uses a local caching scheme and 3.2 uses functools.lru_cache, yet we don't see as much of a slowdown with 3.2. so it seems like the caching behavior is precedent here, but I would revert re.py's caching scheme to the one used in 2.7 if the functools.lru_cache can't be sped up very significantly. ideally lru_cache would be native. also does python include any kind of benchmarking unit tests ? over in SQLA we have an approach that fails if the call-counts of various functions, as measured by cProfile, fall outside of a known range. it's caught many issues like these for me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16389 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16389] re._compiled_typed's lru_cache causes significant degradation of the mako_v2 bench
Nick Coghlan added the comment: Now that Brett has a substantial portion of the benchmark suite running on Py3k, we should see a bit more progress on the PyPy-inspired speed.python.org project (which should make it much easier to catch this kind of regression before it hits a production release). In this case, as I noted in my earlier comment, I think the 3.3 changes to make_key broke an important single-argument fast path that the re module was previously relying on, thus the major degradation in performance on a cache hit. I haven't looked into setting up the benchmark suite on my own machine though, so we won't know for sure until either I get around to doing that, or someone with it already set up tries the change I suggested above. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue16389 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16383] Python 3.3 Permission Error with User Library on Windows
Jim Pattee added the comment: You have been in contact with my friends at Mensa. Further information: Just branching into the library causes a problem with permissions when opening files, even if the library just immediately returns.
