ANNOUNCE: awstats_reader 0.5
ABOUT THE MODULE
AwstatsReader is a pythonic interface to AWStats data cache files. Using
it, you can access year and month via dict-like subscripts, and and
individual data points via both dict-like subscripts and attribute-like
accessors.
As of version 0.5, it includes a script for merging AWStats Cache files.

ABOUT THE AUTHOR
Joshua Kugler (jos...@azariah.com) is a programmer and system administator
with over 10 years of industory experience. He is currently looking for a
job. Happen to have one you could offer him? :)
Resume at: http://jjncj.com/papers/KuglerResume.pdf
DISCLAIMER
==
This is an early-beta release. There are 43 tests which cover most, if not
all of the functionality, but not much documentation. The interface should
be considered stable, but not in concrete. The usage of this project in
a "real world" situation (awstats_cache_merge.py) led to many improvements
to the API.
I wrote this via examples from an AWStats cache file, so I'm sure there are
sections for which I do not have definitions. If you would send me those
sections, I'll be sure to add them.
Right now, this will parse and display cache files from AWStats 6.5. I've
not tested other versions yet, as 6.5 is the only version I've had access
to so far.

What is the contents of 'mykey'? Is it a file object? A string containing
the contents of ~/.ssh/id_rsa? The Paramiko docs indicate mykey should be a
subclass of PKey, probably RSAKey.
So, you'd need to do:
mykey = RSAKey.from_private_key_file('/path/to/private/key/id_rsa')
transport.connect(username = username, pkey = mykey)
Beyond that, I"m not sure. Of course, I've never used Paramiko before.

Yes, but most likely not with pysqlite. The python sqlite3 module in the standard library, and the pysqlite module are both DB-API compliant, which means they probably do not have a method to open the DB read only (as that is usually enforced at the user permission level). If you want to use that flag, take a look at APSW. It is a very thin layer on top of the SQLite C API, and thus supports everything that the C API supports. It is not, however, DB API compliant, but is very close so not hard to pick up. BTW, APSW is written by the same author as pysqlite. j -- http://mail.python.org/mailman/listinfo/python-list

There is a function call to get only one value. I think it's get_first() or some such. Well, the CGI module hasn't had many changes. There was this bug fix a few months back: http://svn.python.org/view?rev=64447&view=rev Diff to previous: http://svn.python.org/view/python/trunk/Lib/cgi.py?rev=64447&r1=58218&r2=64447 For all revisions: http://svn.python.org/view/python/trunk/Lib/cgi.py?rev=67528&view=log It is possible that by fixing a bug, they brought the behavior in line with what it *should* be. Or maybe the browser behavior changed? The server does not care about an "action" attribute. That only tells the browser where to send the data. It is possible the browser did not properly format a request when there was no "action" attribute. Can you provide more details? j -- http://mail.python.org/mailman/listinfo/python-list

Disputing Cookie.py's definition of valid characters
Some investigation today revealed that Cookie.py thinks these are valid
characters for names and values of cookies:
_LegalCharsPatt = r"[\w\d!#%&'~_`><@,:/\$\*\+\-\.\^\|\)\(\?\}\{\=]"
The rest, presumably being encoded via %NN.
I notice that (), {}, and others made the list, but not [].
Is there a reason for that? I didn't find a list of valid characters
anywhere in the cookie RFC (disclaimer: I didn't read the HTTP 1.1 RFC).
The reason this got brought up:
I'm parsing some cookies that have been set by a PHP app (out of my control,
no flames please) and it has cookies of the form name[0], name [1], and so
on which get transformed to arrays on the server side such that:
$_COOKIES['name']
Will be a list with values from name[0], name[1].
Well, when these are parsed by Cookie.py, they simply vanish because it
doesn't like the [ and ] in the cookie names. But these are set
successfully and the browser side, and are sent back to the server
successfully.
Since this is a CherryPy app, it's not as easy as just subclassing the
cookie class I want. I suppose I could sub class and then monkey patch
CherryPy, but that feels nasty. Hmm...local copy of Cookie.py that comes
before /usr/lib/python2.5 in the site path would work too.
Thoughts? Is this a bug in Cookie.py, or is PHP out of spec to send cookies
with [ and ] in the name?

I tried looking through re.py and sre_compile.py, but I can't really see an answer to my question. Experimenting has shown me that re.findall() will return a list with the matches in the order it found them. Am I lucky so far, or does the _sre.c's logic dictate the items will be added in order found? http://svn.python.org/view/python/tags/r25c1/Modules/_sre.c?rev=51334&view=auto (search for "pattern_findall") seems to indicate they will be added in order, but can someone with a better handle on Python internals (and quite frankly, C) confirm this?

Setting an attribute without calling __setattr__()
OK, I'm sure the answer is staring me right in the face--whether that answer
be "you can't do that" or "here's the really easy way--but I am stuck. I'm
writing an object to proxy both lists (subscriptable iterables, really) and
dicts.
My init lookslike this:
def __init__(self, obj=None):
if type(obj).__name__ in 'list|tuple|set|frozenset':
self.me = []
for v in obj:
self.me.append(ObjectProxy(v))
elif type(obj) == dict:
self.me = {}
for k,v in obj.items():
self.me[k] = ObjectProxy(v)
and I have a __setattr__ defined like so:
def __setattr__(self, name, value):
self.me[name] = ObjectProxy(value)
You can probably see the problem.
While doing an init, self.me = {} or self.me = [] calls __setattr__, which
then ends up in an infinite loop, and even it it succeeded
self.me['me'] = {}
is not what I wanted in the first place.
Is there a way to define self.me without it firing __setattr__?
If not, it's not a huge deal, as having this class read-only for now won't
be a problem, but I was just trying to make it read/write.
Thanks!

We've been using Matplotlib for a while, but are looking for alternatives.
I recently came across Chaco (http://code.enthought.com/chaco/) and am
quite impressed with what I see so far.
It's API is very clean, not requiring the "magic functions" (can we say
setp()?) that is required by matplotlib. Very OO, and from what I see of
example code, the API complies with PEP 8 conventions.
Installation was easy (easy_install), but for a couple packages, you will
need GCC, python-dev, and swig.
I haven't dug into it much, but it looks really, really promising.

Not understanding lamdas and scoping
I am trying to use lamdba to generate some functions, and it is not working
the way I'd expect. The code is below, followed by the results I'm
getting. More comments below that.
patterns = (
('[sxz]$', '$','es'),
('[^aeioudgkprt]h$', '$', 'es'),
('[^aeiou]y$', 'y$', 'ies'),
('$', '$', 's'),
)
def z(*a):
print a
def make_pattern(pattern, search, replace):
def compare(word):
z(pattern, search, replace)
return compare
rules = [make_pattern(pattern, search, replace)
for (pattern, search, replace) in patterns]
print 'make pattern'
for rule in rules:
rule('noun')
rules = [lambda word: z(pattern, search, replace)
for (pattern, search, replace) in patterns]
print 'lambda/list comprehension'
for rule in rules:
rule('noun')
rules = []
for pattern, search, replace in patterns:
rules.append(lambda word: z(pattern, search, replace))
print 'lamda/for loop'
for rule in rules:
rule('noun')
Ouptut:
make pattern
('[sxz]$', '$', 'es')
('[^aeioudgkprt]h$', '$', 'es')
('[^aeiou]y$', 'y$', 'ies')
('$', '$', 's')
lambda/list comprehension
('$', '$', 's')
('$', '$', 's')
('$', '$', 's')
('$', '$', 's')
lamda/for loop
('$', '$', 's')
('$', '$', 's')
('$', '$', 's')
('$', '$', 's')
Of course, in my real code, I'm not calling z(), but a couple of RE
search/replace functions (yes, I'm working on the Dive Into Python
pluralizer).
The first result is obviously the correct one. But the next two don't make
sense. Why do all the functions returned by lamda have the last input
values?
What am I missing?
OK, I figured out if I did this:
def make_pattern(pattern, search, replace):
return lambda word: z(pattern, search, replace)
it would give correct results. So, is there some scoping issue with lambda
that I'm not seeing?
Thanks!

What is the import path? The current directory in PSP might not be the

import your helper module to see what paths you're dealing with.

What you probably don't realize, is that in 99.9% of the situations you've come across, PHP is already a process running all the time. It's called mod_php, and it's a PHP interpreter running inside of apache, thus a "long running process." It's just not as obvious. You can do the same thing with Python via the mod_python module, thus putting the python interpreter (instead of the PHP interpreter) inside the Apache process. Other web servers have similar setups.

I found (at least) two areas where lots of code is unavoidable:
configuration handling and error handling. That said, you could use
configparse (or configobj) to set the defaults of all your command line
options, like so:
cfg = configobj.ConfigObj('file.ini', file_error=True)
parser.add_option('--opt', dest='opt', default=cfg.get('opt', None)

No, I haven't, but I do know for a fact that the only location of the module
found is where I think it is. There are no other modules on the system (or
in the search path) named _modulename.

That was in the original code to silently ignore things like a README file
or a directory that didn't have a __init__.py file. The code I posted was
from my benchmarking script. The code in the framework does a listdir()
and goes through that list trying to import. We'll probably "smarten up"
that code a bit, but for now it works.

A directory and a file that aren't referenced in my test, but are
in the framework's import attempts (see listdir() comment above).
Regardless, setting sys.path to just one directory speeds up both the
benchmark and the framework.

As I said above, no I haven't, but I will just to double check.
On Linux, print x, x.__name__ produces the expected result whether I have
one element in sys.path or all of them. On Windows, same result.

I don't know, but it does. Right now, we're just importing empty modules.
Once those modules have imports of their own, my "fix" will probably fall
apart, and we'll be back to square one.
> What directory tree walking?? Should be none

I know, that's the crazy thing...there should be no directory tree walking
or other filesystem activity after finding the module. But setting
sys.path to one element does make a difference; that can be seen. I don't
know the internal implementation of __import__, so I can't really comment
beyond my results. Maybe I need to strace a python run.

'' would be whereever I start the benchmark script (~/bin), or whereever the
framework is started from, probably from the web server's home directory,
or from ~/bin when I'm profiling the framework.

(More) Re: Is __import__ known to be slow in windows?
Ok, so we have this code:
t = timeit.Timer(stmt='r()', setup='from __main__ import r')
sys.path.insert(0,'/path/to/code')
def r():
for m in ['three','module','names']:
try:
x = __import__(m)
except ImportError, e:
if not e.message.startswith('No module named'):
raise
x = None
Each of those three module names is a directory under /path/to/code with an
empty __init_.py.
On Linux, the run of that code for 1000 iterations takes 0.014 CPU seconds
with 0.007 of that spent in __import__().
On Windows (with on-access checking turned off), 1000 iterations takes 7.9
seconds, with 7.851 seconds of that spent in __import__().
Let's try something...let's modify the code a bit:
sys.path = ['/path/to/code']
def r():
for m in ['three','module','names']:
x = __import__(m)
x = None
cProfile.run('t.timeit(number=%s)' % number, 'stat_file')
p = pstats.Stats('stat_file')
p.sort_stats('time', 'cum').print_stats(.5)
Now, with only my directory in sys.path, the run times are:
Linux: 0.0013 (0.006 spent in __import__)
Windows: 0.0012 (0.007 spent in __import__)
So, it appears walking the directory trees is what is costing the time.

So, not identical (actually, longer on linux) but similar.
Interesting, at any rate.

Re: Is __import__ known to be slow in windows?
> What modules are you __import__ing, and what is platform-dependent in > each? The only thing we're importing __import__ are some modules of ours, with no sytem dependent code in them at all. Some of them are even empty modules, as was suggested by one response (for benchmarking purposes). Turning off Symantec's on-access checking shaved about a bunch of time off the time spent in __import__ (10 seconds vs 16), but still too high. Commenting out the import of the only system dependent code we have in our project (which we don't "manually" import via an __import__ call) produced no change in run time. So, we've found a major culprit. I'll see if I can find more. Thanks for the pointers so far. j -- http://mail.python.org/mailman/listinfo/python-list
Is __import__ known to be slow in windows?
[I tried googling for this, didn't find anything relevant.] We've recently been doing some profiling on a project of ours. It runs quite fast on Linux but *really* bogs down on Windows 2003. We initially thought it was the simplejson libraries (we don't use the C extensions) but profiling proved otherwise. We have a function that does some runtime imports via calls to __import__. We ran 1000 iterations (we used cProfile) of the application (web app). There were eight calls to __import__ per iteration, so 8000 calls total. Identical hardware, by the way. On Linux (Debian Etch, Python 2.5.1) Total time was 2.793 CPU seconds, with __import__ using 1.059 seconds of that. So, 37% of the time was spent in import. Not great, but not a show stopper. On Windows 2003 (R2, Python 2.5.1) Total time was 18.532 CPU seconds, with __import__ using 16.330 seconds (88%) of that. So, Linux spends 1.734 seconds on non-import activities, and Windows spends 2.202 seconds on non-import activities. Pretty close. But 16.3 seconds on import!? Is this a known deficiency in Windows' Python import calls, or is there something deeper going on here? Pointers, suggestions, and URLs welcome. j -- http://mail.python.org/mailman/listinfo/python-list
