ANN : Karrigell-4.3.6 released
Hi, A new version of the Karrigell web framework for Python 3.2+ has just been released on http://code.google.com/p/karrigell/ One of the oldest Python web frameworks (the first version was released back in 2002), it now has 2 main versions, one for Python 2 and another one for Python 3. The Python 2.x version is available at http://karrigell.sf.net ; this branch is maintained, but no new feature is going to be developed All the development work is now focused on the version for Python 3. The first release was published in February and we are already at the 10th release Karrigell's design is about simplicity for the programmer and integration of all the web environment in the scripts namespace. For instance, the Hello world script requires 2 lines : def index(): return Hello world All the HTML tags are available as classes in the scripts namespace : def index(): return HTML(BODY(Hello world)) To build an HTML document as a tree, the HTML tags objects support the operators + (add brother) and = (add child) : def index(): form = FORM(action=insert,method=post) form = INPUT(name=foo)+BR()+INPUT(name=bar) form = INPUT(Type=submit,value=Ok) return HTML(BODY(form)) The scripts can be served by a built-in web server, or through the Apache server, either on CGI mode or using the WSGI interface The package obvioulsy has built-in support for usual features such as cookie and session management, localization, user login/logout/role management. It also includes a complete documentation, with tutorial and a set of how-to's A helpful and friendly community welcomes users at http://groups.google.com/group/karrigell Enjoy !

SSE4a with ctypes in python? (gcc __builtin_popcount)
Hi guys,
Here is the sample code
http://stackoverflow.com/questions/6389841/efficiently-find-binary-strings-with-low-hamming-distance-in-large-set/6390606#6390606
static inline int distance(unsigned x, unsigned y)
{
return __builtin_popcount(x^y);
}
Is it possible to rewrite the above gcc code in python using ctypes
(preferably Win/*nix compatible)?
TIA!

No; the (gcc-injected) functions starting with __builtin_* are not real functions in the sense that they can be called by calling into a library, but rather are converted to a series of assembler instructions by the compiler directly. Wrapping this (distance) primitive by writing a C-module for Python, thus exposing the respective gcc-generated assembler code to Python through a module, won't yield any relevant speedups either, because most of the time will be spent in the call sequence for calling the function, and not in the actual computation. -- --- Heiko. -- http://mail.python.org/mailman/listinfo/python-list

locate executables for different platforms

I would like to rewrite this thing being able to: - detect the OS - find the right executable version - get the path and run it It would be nice to still be able to use pkg_resources, but at that point I think I would need to store all the executables in another egg, is that correct?

Tweepy: Invalid arguments at function call (tweepy.Stream())

C API: Making a context manager
I am currently rewritting a class using the Python C API to improve performance of it, however I have not been able to find any documentation about how to make a context manager using the C API. The code I am working to produce is the following (its a method of a class): @contextlib.contextmanager def connected(self, *args, **kwargs): connection = self.connect(*args, **kwargs) try: yield finally: connection.disconnect() For this, my first question is: is there any built-in method to make this type of method in the C API? If not, is there a slot on the type object I am missing for __enter__ and __exit__, or should just be defined using the PyMethodDef struct on the class (presumably named the same as the Python functions)?

Efficient, built-in way to determine if string has non-ASCII chars outside ASCII 32-127, CRLF, Tab?
Wondering if there's a fast/efficient built-in way to determine if a string has non-ASCII chars outside the range ASCII 32-127, CR, LF, or Tab?

print out its speed. os.popen seems to be the right solution for the
ifconfig command, but it doesn't seem to like me passing the interface
variable as an argument. Code snippet is below:
#!/usr/bin/python
# Quick and dirty script to print out available interfaces and their
speed
# Initializations
output = Interface: %s Speed: %s
import os, socket, types
fp = os.popen(ifconfig -a)
dat=fp.read()
dat=dat.split('\n')
for line in dat:
if line[10:20] == Link encap:
interface=line[:9]
cmd = 'ethtool %interface'
print cmd
gp = os.popen(cmd)
fat=gp.read()
fat=fat.split('\n')
=
I'm printing out cmd in an attempt to debug, and interface seems
to be passed as a string and not a variable. Obviously I'm a newbie,
and I'm hoping this is a simple syntax issue. Thanks in advance!

No offense Dave, but do you really think that making a copy of as much as a terabyte of data is *more* efficient than merely scanning the data and stopping on the first non-ASCII character you see? There is no way of telling whether a string includes non-ASCII characters without actually inspecting each character. So in the event that the string *is* fully ASCII text, you have to check every character, there can be no shortcuts. However, there is a shortcut if the string isn't fully ASCII text: once you've found a single non-text character, stop. So the absolute least amount of work you can do is: # Define legal characters: LEGAL = ''.join(chr(n) for n in range(32, 128)) + '\n\r\t\f' # everybody forgets about formfeed... \f # and are you sure you want to include chr(127) as a text char? def is_ascii_text(text): for c in text: if c not in LEGAL: return False return True Algorithmically, that's as efficient as possible: there's no faster way of performing the test, although one implementation may be faster or slower than another. (PyPy is likely to be faster than CPython, for example.) But can we get better in Python? Yes, I think so. First off, CPython is optimized for local variable lookups over globals, and since you are looking up the global LEGAL potentially 1 times, even a 1% saving per lookup will help a lot. So the first step is to make a local reference, by adding this line just above the for loop: legal = LEGAL But we can do even better still. Each time we test for c not in legal, we do a linear search of 100 characters. On average, that will mean comparing 50 characters for equality at best. We can do better by using a set or frozenset, which gives us approximately constant time lookups: legal = frozenset(LEGAL) Finally, we can try to do as much work as possible in fast C code and as little as necessary in relatively slow Python: def is_ascii_text(text): legal = frozenset(LEGAL) return all(c in legal for c in text) Since all() is guaranteed to keep short-cut semantics, that will be as fast as possible in Python, and quite possibly just as fast as any C extension you might write. If that's still too slow, use smaller files or get a faster computer :) -- Steven -- http://mail.python.org/mailman/listinfo/python-list

return all(
(' ' = c = '\x7a') or

But Steven's main points are all spot on: (1) use an O(1) lookup;
(2) return at the first sign of trouble; and (3) push it into the
C implementation rather than a for-loop. (and the locals are
faster in CPython is something I didn't know)

Incidentally, on the Pentium family, there's a machine instruction for that, to do the whole loop in one instruction (with rep prefix). I don't know if the library version is done so. And with the delete option, it wouldn't be copying anything, if the data is all legal. As for processing a gig of data, I never said to do it all in one pass. Process it maybe 4k at a time, and quit the first time you encounter a character not in the table. But I didn't try to post any code, since the OP never specified Python version, nor the encoding of the data. He just said string. And we all know that without measuring, it's all speculation.

Are you arguing with me? I was agreeing with you, I thought, that
translate would be faster than a regex. I also pointed out that the
delete function was available as , but OTOH, that might be a little
slow because I think it does the deletion before the translate. I
think I'd just do something like this:
transtab = ''.join(' ' if 32 = x = 126 else chr(x) for x in range(256))
'abc\x05\def\x0aghi'.translate(transtab).replace(' ', '')

None of the above. It assumes nothing. It takes a string of characters,
end of story.
For reference the string is これは in the 'shift-jis' encoding.
No it is not. The way to get aunicodeliteralwith those characters is
to use aunicode-aware editor or terminal:
s = u'これは'

You are confusing characters with bytes. I believe that what you are
thinking of is the following: you start with a byte string, and then
decode it intounicode:
bytes = '\x82\xb1\x82\xea\x82\xcd' # not u'...'
text = bytes.decode('shift-jis')
print text
これは
If you get the encoding wrong, you will get the wrong characters:

If you start with theUnicodecharacters, you can encode it into various
byte strings:
s = u'これは'
s.encode('shift-jis')

If calling subprocess.Popen() is supposed to work from threads without any particular protection, then a lock is needed in subprocess.py: try: spawn_lock.acquire() gc.disable() try: os.fork() except: ... finally: spawn_lock.release() Such issues are very difficult to reproduce and to track. The documentation should at least mention that calling gc.enable() may cause subprocess() to hang!

[issue13302] Clarification needed in C API arg parsing
New submission from Sandro Tosi sandro.t...@gmail.com: Hello, given I can't fully comprehend the user request (sent on docs@ as of http://mail.python.org/pipermail/docs/2011-September/005791.html), I'm just echoing it : recently I embedded Python into one of my applications, which included some string parsing. In my opinion the doc page about parsing arguments (http://docs.python.org/c-api/arg.html) is missing the information, that you must not free the returned const char *, like e.g. said here (http://docs.python.org/c-api/string.html#PyString_AsString).

It could also be due to a firewall setting (e.g., drop incoming connections requests when the connection rate is too high). -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue11812 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue12797] io.FileIO and io.open should support openat
Antoine Pitrou pit...@free.fr added the comment: Updated patch: * checks for long overflow * raises original exception if opener returns null * makes it explicit that opener must return an open file descriptor. This looks good to me. You just need to add a versionchanged attribute in the documentation. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12797 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13295] html5 template for Lib/http/server.py
Martin v. Löwis mar...@v.loewis.de added the comment: I declare the original issue closed - there is no reason to switch to HTML 5 in this code. There are side issues, such as the HTML 3.2 perhaps being incorrect; people who want to commit patches in that respect can just go ahead. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13295 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue13303] Sporadic importlib failures: FileNotFoundError on os.rename()
Charles-François Natali neolo...@free.fr added the comment: (it does sound a bit overkill to me :-)) Well, it depends on what we want: - if having a stale bytecode file indefinitely is acceptable, then the '.tmp' suffix approach is OK - if not, then we should use pseudo-random files If you go that way, you should also modify Python/import.c to use a similar logic. I think I would use mkstemp(), but yes, that's the idea. So, what do you think? -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue13303 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
