You are importing the time module first, then import some symbols from the 
time module. This seems redundant to me. Note that after the "import 
time", the name "time" refers to the module you imported...

> time = config.get("myvars", "time")

...but after this line it refers to something else, because you rebound it 
to the object returned by "config.get(...)".

You're on the right track...

...because this time here doesn't refer to the time module but to the 
output of "config.get(...)"! This object is a string object (type "str"), 
and Python complains:

> AttributeError: 'str' object has no attribute 'sleep'


I Hope that clarifies something! ;)

That's what function parameters are for:

def safe_copy(fname):
 

for x in fname:
safe_copy(x)

That way fname is a filename inside safe_copy() and a list of filenames on 
the global module level. "fname" for a list and "files" for a single file 
are still badly chosen names because they confuse the reader instead of 
clarifying what's going on.

I strongly recommend that you work through a python tutorial for non-
programmers before you continue with your efforts.

os.stat bug?

[Laszlo Nagy]

  Hi All,

I have a Python program that goes up to 100% CPU. Just like this (top):

  PID USERNAME   THR PRI NICE   SIZERES STATE   C   TIME   WCPU 
COMMAND
80212 user1   2  440 70520K 16212K select  1   0:30 100.00% 
/usr/local/bin/python process_updates_ss_od.py -l 10


I have added extra logs and it turns out that there are two threads. One 
thread is calling "time.sleep()" and the other is calling "os.stat" 
call. (Actually it is calling os.path.isfile, but I hunted down the last 
link in the chain.) The most interesting thing is that the process is in 
"SELECT" state. As far as I know, CPU load should be 0% because "select" 
state should block program execution until the I/O completes.


I must also tell you that the os.stat call is taking long because this 
system has about 7 million files on a slow disk. It would be normal for 
an os.stat call to return after 10 seconds. I have no problem with that. 
But I think that the 100% CPU is not acceptable. I guess that the code 
is running in kernel mode. I think this because I can send a KILL signal 
to it and the state changes to the following:



  PID USERNAME   THR PRI NICE   SIZERES STATE   C   TIME   WCPU 
COMMAND
80212 user1   2  440 70520K 15256K STOP5   1:27 100.00% 
/usr/local/bin/python process_updates_ss_od.py -l 10


So the state of the process changes to "STOP", but the program does not 
stop until the os.stat call returns back (sometimes for 30 seconds).


Could it be a problem with the operation system? Is it possible that an 
os.stat call requires 100% CPU power from the OS? Or is it a problem 
with the Python implementation?


(Unfortunately I cannot give you an example program. Giving an example 
would require giving you a slow I/O device with millions of files on it.)


OS version: FreeBSD 8.1-STABLE amd64
Python version: 2.6.6

Thanks,

What's your operating system and file system? A better file system or
system setting may increase your performance a lot. XFS or ext3 / ext4
with hashed directory index increases the file lookup part from O(n) to
O(1).

It's mostly likely a problem with the OS, hardware and/or your
configuration. Python doesn't come with its own stat() implementation.
os.stat() just wraps the libc's stat() function. The heavy lifting is
done inside libc and the kernel.

Proxy authentication required

You really seemed to know what you are talking about. :)

I'm sorry if I offended you in any way. I had to clarify the meaning of
st_ctime many times in the past because people confused it for the
creation ts of the file.

For instance this confusing has lead to a confusing bug in our code base
a while ago. After I fixed the ownership of a bunch of files, the ctime
was newer than the mtime. A library couldn't handle that and we got
ourself a nice exception.

There is a chance that the CPU usage actually comes from the thread
doing sleep(). If you have a very short sleep time, and a loop around
it, it may spin in this loop.

If it's not that, and if it's not any other unrelated application that
uses CPU that you didn't mention, then chances are high that it's indeed
the file system code of your operating system that consumes that much
CPU time.

Yes. top shows 2 thread in this process, and full 100% CPU time is

No. What I am saying is the code is written has been well tested and

there is potential for bugs. I think I am just been practical here,
evidently I can't think of everything, but there are some clear and

this in the terms of the code (sorry)...but for example the model
estimates plant photosynthesis and then allocates the carbon. So one
clear example is that the model cuts back carbon production if there
is water stress for the plant. This involves "removing" carbon from
the state. Clearly if you ended up in a situation where there is
negative carbon in a leaf, i.e. the leaf doesn't exist well this is
not physically possible and would be a code issue. Whilst this is
unlikely I think it would be nice to have a catch for it. Another
example would be the amount of soil water available to the plant,
again there can be zero but not negative soil water. It wouldn't be
meaningful. I hope that makes sense?

Not that much. You'll spot bugs where negative numbers will be set to 
some attribute but what if 42 is put instead of 43 in one of your 
attribute ? Same consequence, it will mess up with your model but none 
of your check will spot that error.


Try to identify those complicated functions you mentioned, and write 
unitary tests for them. Use a set of input parameters with the expected 
function return value. That way you'll be able to spot errors, whether 
the attribute is negative or not.

Hi,

Yes you make a good point. I think what I was trying to get across is
there are certain scenarios which can't physically happen and they are
straight forward to check for. I just thought it might be nice to add
a check for these. However you make a good case and I definitely take
your point. I guess I should look into unitary tests then (any
suggestions?)

It's the OS kernel. If it was Python or the C library, sending SIGKILL
would result in immediate termination.

Is the disk interface operating in PIO mode? A slow disk shouldn't cause
100% CPU consumption; the OS would just get on with something else (or
just idle) while waiting for data to become available. But if it's
having to copy data from the controller one word at a time, that could
cause it (and would also make the disk appear slow).

Oh don't be obtuse, dude. GUI automation is much used for webbots and data

difficult if not impossible. With scriptable OSes, sites and browsers you can

 Most other tools are not object oriented you end up writing stuff

Remember that backslash is used for string escapes in Python; so that
should be "domain\\username" in order to get 1 literal backslash. I
suspect this is the cause of your proxy authentication problem.

> opener = urllib.request.build_opener(hc, hp)

Are you sure that's the right order for the handlers? (I don't know myself.)

The setup.py code is trying to be too clever and the released package is 
missing files it requires.  The easiest way to fix it is to simply get the 
latests code from the VCS which contains all the required files.  That's what I 
did anyway:

brz branch lp:txjsonrpc

Then just do your usual favourite incantation of "python setup.py install 
--magic-options-to-make-setuptools-sane-for-you".

Decorator Syntax

[Mike Patterson]

In my Python class the other day, the professor was going over
decorators and he briefly mentioned that there had been this huge
debate about the syntax and using the @ sign to signify decorators.

I read about the alternative forms proposed here (http://
www.python.org/dev/peps/pep-0318/#syntax-alternatives).

Has anyone thought about just using dec to declare a decorator?

For example:
dec dec2
dec dec1
def func(arg1, arg2, ...):
pass

did this a long time ago when behind a corporate proxy server worked
then might be a start for you
I am fuzzy on the details.

import httplib
import base64
import getpass
def getWebPage(userName='YourUserName',httpPage='http://
weather.noaa.gov/weather/current/KRIC.html',outFilePath=None):
# 1. connect to the proxy
h1 = httplib.HTTP("proxyconf",)

# 2. give the absolute URL in the request
h1.putrequest('GET', 'http://weather.noaa.gov/weather/current/
KRIC.html')

h1.putheader('Accept', 'text/html')
h1.putheader('Accept', 'text/plain')
password = getpass.getpass()
# 3. set the header with a base64 encoding of user-id:passwd
userString = "%s:%s" % (userName,password)
auth = "Basic " + base64.encodestring(userString)
h1.putheader('Proxy-Authorization', auth)
h1.endheaders()

# 4. get the page
errcode, errmsg, headers = h1.getreply()

print errcode
print errmsg
print headers

f=h1.getfile()
if(not outFilePath):
for line in f.readlines():
print line
else:
try:
outFile = open(outFilePath,'w')

dec and def look too similar. It would get confusing. Also, it
wouldn't be immediately obvious that the line is associated with the
function declaration below. The whole point in the decorators is that
it makes it easier to tell that the function is being wrapped.

Hi all, my name is Juan and I suscribed to this website called "Free
Software University", opened recently. One of the goals of this
website is making some free high quality courses, one of them about
Python.

I want to say this message is not SPAM, is a call for every one who
can and wants help us to make several good courses about Python, those
will be in english and spanish languages (and any other translation if
is aviable). We're allways open to new suggets, changes, contents,
etc...

Best regads.

Also "dec" would then have to become a keyword.  Unnecessary
keywording is frowned upon because it breaks any script that happens
to use the keyword as a name, thus creating backward
incompatibilities.  And I'm willing to bet that there are plenty of
scripts out there that use "dec" as a name for Decimal objects.

Reasonably sure it does, with slight modification. Change "python" to
the full path of your pythonw.exe executable.
If it still doesn't work, please include the error message you're getting.

Problem with keyboard up/down arrows in Python 2.4 interpreter

[Julien]

Hi,

I'm having problems when typing the up/down arrows in the Python 2.4
interpreter (exact version: Python 2.4.6 (#1, Mar  3 2011, 15:45:53)
[GCC 4.2.1 (Apple Inc. build 5664)] on darwin).

When I press the up arrow it outputs "^[[A" and when I press the down
arrow it outputs "^[[B".

I've google it and it looks like it might be an issue with the
readline not being installed or configured properly. Is that correct?
If so, how can I fix this issue?

Many thanks.

Kind regards,

Julien

How did you install Python? If you used Macports, it looks like
readline support is a separate port for 2.4. Try installing
py-readline.
