ldap search and Tuple

[Alejandro Decchi]

Dear,
I am writing to ask you which is the most profitable way, to get the last
uidNumber.
With ldap search create a tuple with a lot of values as follows:

('dc=xxx,dc=xxx,dc=xx', {'uid': ['pepe'], 'objectClass': ['inetOrgPerson',
'mailUser', 'shadowAccount', 'amavisAccount', 'shell', 'wiki'],'uidNumber':
['']}]

I hope you can guide me and suggest any method.

Thank you

Package data distribution and installation

[Alejandro Dubrovsky]

I've got a script that is an executable and it reads template files that 
should be packaged with the script.  How do I tell the script where to 
find the templates?

In distutils, there's a package_data option, but that installs the 
templates under the /usr/lib/pythonX.XX/...  directory, which seems like 
the wrong directory in the unix hierarchy.  Traditionally, this kind of 
data goes under /usr/share. There's also the data_files option, but that 
can be overridden on the install command line with --install-data 
directory, and the scripts/modules don't get informed (or do they? if so, 
how?)

Googling around, people seem to write big install scripts to get around 
this, subclassing from distutils/setuptools and "manually" replacing 
certain tags in their modules with the final data directory.  Is that the 
only way to do this properly?  Is there a pre-packaged solution not in 
Python's library that takes care of it, maybe similarly to the auto-tools 
config.h.in substitution?  If so, could someone point me to it?

Thanks

Nope i gives:

Need help from someone that have PIL installed

[alejandro]

Can please someone run this little script that should output characters like 
¾æè¹ð in an image.
If it does it correctly can you tell me what OS, python version & PIL 
version you have?
Or better if someone can tell me why this is not working properly on my PC? 
(Win XP, PIL 1.1.6., Python 2.6...)
I don't recive any error it's just that the characters outputed in the image 
are not characters... more like symbols...

# encoding:utf-8

from PIL import Image
import ImageDraw
import ImageFont


img = Image.new("RGBA",(250,40))

#--- making the image transparent
pixdata = img.load()

for y in xrange(img.size[1]):
for x in xrange(img.size[0]):
if pixdata[x, y] == (255, 255, 255, 255):
pixdata[x, y] = (255, 255, 255, 0)

#- drawing text
draw = ImageDraw.Draw(img)
arial = ImageFont.truetype("arial.ttf",32)  # needs path to font, my font 
was in the same folder as the script
string = "proba test ¾æèð¹"
draw.text((20,8),string ,font=arial, fill="red")

# write
img.save("img2.png", "PNG")

Re: Printing plain text with exact positioning on Windows

[alejandro]

Did you mean borderless printing?
Every printer needs his margins, some more some less. Some printers have the 
ability to do borderless printing but usualy they can do it only on special 
or photo paper. So you can adjust the pdf as you wish, even with no margins, 
and then try to find under printer options "borderless printing". That is 
why I didn't understand :-)) it is a printer thing not pdf!

Re: Printing plain text with exact positioning on Windows

[alejandro]

Don't remember much.. but maybe you could play with canvas?
I think i don't undertand(i am a croatian so english is not my mother 
language). If you have the need that the pdf and the printer setup have lets 
say the same paper size, sorry but can't help.
If you want lets say different printer margins for different documents/pages 
just calculate them.
A4 is 210x297mm and you have need for a margin of 10mm..
width = 210 - margin
height = 297 - margin
now for positioning use the variables instead the absolute positioning..

i think that reportlab has some methods that alow you to position 
text/photos from the left top corner instead the normal positioning.

Don't know if I helped you in any way...

Good luck!

Ok, thanks. In that scenario I would also need to be able to

Re: Got undefined symbol: _PyUnicodeUCS2_AsDefaultEncodedString on OpenSuSE 11.1

[Alejandro Valdez]

Hello Mark, thank you a lot for your hints, I compiled python using
the --enable-unicode=ucs4 parameter in configure and I could
successfully install setuptools (Anyway I'm a little suspicious about
my compiled binaries...).

You are right about the environment variables, I have set PYTHONPATH
and PYTHONHOME to:
PYTHONPATH=$HOME/python/lib/python2.6/site-packages
PYTHONHOME=$HOME/python

The compiler issued some warnings, two of them (related to Unicode)
called my attention:

Should I ignore them?

WinAppDbg module v1.1 is out!

[Mario Alejandro Vilas Jerez]

What is WinAppDbg?
==

The WinAppDbg python module allows developers to quickly code
instrumentation
scripts in Python under a Windows environment.

It uses ctypes to wrap many Win32 API calls related to debugging, and
provides
an object-oriented abstraction layer to manipulate threads, libraries and
processes, attach your script as a debugger, trace execution, hook API
calls,
handle events in your debugee and set breakpoints of different kinds (code,
hardware and memory). Additionally it has no native code at all, making it
easier to maintain or modify than other debuggers on Windows.

The intended audience are QA engineers and software security auditors
wishing to
test / fuzz Windows applications with quickly coded Python scripts. Several
ready to use utilities are shipped and can be used for this purposes.

Current features also include disassembling x86 native code (using the open
source diStorm project, see http://ragestorm.net/distorm/), debugging
multiple
processes simultaneously and produce a detailed log of application crashes,
useful for fuzzing and automated testing.


Where can I find WinAppDbg?

The WinAppDbg project is currently hosted at Sourceforge, and can be found
at:

http://winappdbg.sourceforge.net/

It's also hosted at the Python Package Index (PyPi):

According to this document (http://heather.cs.ucdavis.edu/~matloff/

"Here each thread really is a process, and for example will show up on
Unix systems when one runs the appropriate ps process-list command,

If you look at my original post, pstree does show different PIDs for
the threads.

Get thread pid

[Alejandro]

Hi:

I have Python program running under Linux, that create several
threads, and I want to now the corresponding PID of the threads.

In each of the threads I have

def run(self):
pid = os.getpid()
logger.critical('process ID: %s', pid)

However, the reported PID is the father number, not the PID of the new
thread. Is there a way to get the PID of the thread?

To illustrate this further, this is the output of pstree when the PID
of the main Python thread is 9197:

$pstree -p 9197
python(9197)─┬─{python}(9555)
 ├─{python}(9556)
 ├─{python}(9557)
 ├─{python}(9558)

 ├─{python}(9560)
 ├─{python}(9561)
 ├─{python}(9562)
 ├─{python}(9563)
 └─{python}(9564

I want each thread to report its PID number, in this case 9555, 9556,
etc., but with os.getpid() is get 9197.

Finding multiple of a decimal number in a floating point list

[Alejandro]

Hi:

I need to find the multiples of a decimal number in a floating point
list. For instance, if a have the list [0,0.01,0.02,...1], I want the
multiples of 0.2: [0, 0.2,0.4,0.6,0.8,1].

With integers this problem is easy, just test for (i%n == 0), where i
is the number I am testing, and n is the multiple. Given the finite
resolution of floating point numbers, this is more complicated for
float.

I came with this solution:

from numpy import arange
from math import modf, fabs

float_range = arange(0, 1, 0.01)
for f in float_range:
m = modf(f / 0.2)[0]
if m<1e-13 or fabs(1-m)<1e-13:
print f
# Do something else

This code works, however, I found it a little ugly. Is there a better
way to do the same?

exec and closures

[Alejandro Dubrovsky]

About a month ago, there was a thread on auto-assigning decorators for 
__init__.  One by André Roberge is here:
http://groups.google.com/group/comp.lang.python/browse_frm/
thread/32b421bbe6caaeed/0bcd17b1fa4fb07c?#0bcd17b1fa4fb07c

This works well for simple cases, but doesn't take keyword arguments or 
set default values.  I wrote a more extensive version implementing python 
call semantics, but it seemed awkard to be repeating something the 
compiler does already, so I tried execing a function definition on the 
fly with the right parameters that would function as the decorator.  Like 
this  (adjust the indentation variable if it throws a syntax error)

def autoassign(_init_):
import inspect
import functools

argnames, _, _, defaults = inspect.getargspec(_init_)
argnames = argnames[1:]

indentation = ''
settings = ['self.%s = %s' % (arg[1:], arg) for arg in argnames 
if arg[0] == '_']

if len(settings) <= 0:
return _init_

if defaults is None:
args = argnames[:]
else:
args = argnames[:-len(defaults)]
for key, value in zip(argnames[-len(defaults):],defaults):
args.append('%s=%s' % (key, repr(value)))

template = """def _autoassign(self, %(args)s):
%(setting)s
_init_(self, %(argnames)s)
""" % {'args' : ", ".join(args), 'setting' : "\n".join(['%s%s' % 
(indentation, setting) for setting
in settings]), 'argnames' : ', '.join(argnames)}

try:
exec template
except SyntaxError, e:
raise SyntaxError('%s. line: %s. offset %s:\n%s' % 
(e.msg, e.lineno, e.offset, template))
return _autoassign


Which creates what looked like the right template, but when instantiating 
a class that uses that (eg
class A(object):
@autoassign
def __init__(self,_a):
pass
a = A(3)

it throws a
NameError: global name '_init_' is not defined

Is there a way to bind the _init_ name at exec time?

Thanks,

How to modify the content of an email

Hello, I'm trying to make a python script that take an email in (raw)
text format, and add a footer to the text (or html) body of the email.

I'm aware of the email and email.mime modules, but I can't figure out
how to identify 'the main text (or html) content' from the email, and
how to be sure that I don't incorrectly identify a txt (or html)
attach as the main content of the email.

By 'main text (or html) content' I mean the text (or html) that is
showed by a Mail User Agent when it display the email to the

wxpython: Redirect the stdout to a textctrl

[Alejandro]

Hi:

I want to redirect stdout to a textctrl I have. From what I read in
the wxpython documentation, I can use the wxLogTextCtrl class to do
this. I am doing the following:

class MyGui(gui.MyFrame):  #gui.MyFrame generated by wxGlade
def __init__(self, *args, **kwds):
gui.MyFrame.__init__(self, *args, **kwds)
# ... code removed ...
wx.Log_SetActiveTarget(wx.LogTextCtrl(self.text_ctrl_2))
print 'foo' #to test the redirection

if __name__ == "__main__":
app = wx.App(redirect=wx.LogTextCtrl)
wx.InitAllImageHandlers()
gui = MyGui(None, -1, "")
app.SetTopWindow(gui)
gui.Show()
app.MainLoop()

However, the output instead of going to my textctrl, goes to a new
window named "xwPython: stdout/stderr".

What am I missing?

Just guessing (since I haven't tested this), switching from doing it line by
line to big chunks (whatever will fit in memory) at a time would help, but
I don't think you can get close to the speed of grep  (eg 
while True:
chunk = thefile.read(1))
if not len(chunk): break
for x in theRE.findall(chunk):
.  
)
Function calls in python are expensive.

I'm new to this list(this is my first message) and to Python also (I'm

you can create an myStr object on the fly, something like:

If you are using python 2.5, then you can use functools.partial, otherwise
lookup one of the many curry implementations, like the ones found in
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/52549

One found in the comments of that page by Scott David Daniels:

def curry(*args, **kwargs):
function, args = args[0], args[1:]
def result(*rest, **kwrest):
combined = kwargs.copy()
combined.update(kwrest)
return function(*args + rest, **combined)
return result


so, in your case:

f = lambda x,y: (x,y)
f2 = functools.partial(f,1)
>>> f2(3)
1,3

You are right. For instance, the 485COSR converter, from B&B

urllib2 through basic auth'ed proxy

[Alejandro Dubrovsky]

I see from googling around that this is a popular topic, but I haven't seen
anyone saying "ah, yes, that works", so here it goes.

How does one connect through a proxy which requires basic authorisation?
The following code, stolen from somewhere, fails with a 407:

proxy_handler = urllib2.ProxyHandler({"http" :
"http://the.proxy.address:3128"})
proxy_auth_handler = urllib2.ProxyBasicAuthHandler()
proxy_auth_handler.add_password("The name of the realm sniffed from
telnetting to the proxy and doing a
get",'the.proxy.address','theusername','thepassword')
opener = urllib2.build_opener(proxy_handler, proxy_auth_handler)
urllib2.install_opener(opener)
f = urllib2.urlopen('http://www.google.com/')


I still get a 407 if I set the realm to None, I change host to the
'http://the.proxy.address/' form or even 'http://the.proxy.address:3128'
form.

The proxy is squid.  Python version is 2.3.4 (I read that this version has a
problem in that it introduces an extra return after the authorisation, but
it isn't even getting to that bit). And yes, going through firefox,
everything works fine.

Can anyone explain me why this fails, or more importantly, code that would
work? 

Thanks,
alejandro

I know it can be difficult/impossible. By the way, I am coding in
Linux, but want my code to be portable between Windows and Linux(!).

I will rethink the whole issue. May be I will use the time.sleep
alternative, taking a good margin to manage the uncertainty of the

pySerial: write in a blocking mode

[Alejandro]

Hi:

I'm using pySerial to talk to a RS232 to RS485 converter. In order to
control the converter, I need to control the DTR line to enable/disable
de RS485 driver. In particular, I need to :

write a character to the serial port
set the DTR line to level 1 _after_ the last bit of the character is
send

So I tried this (ser is the serial port object):

ser.write(x)
ser.setDTR(1)

The problem with this is that the ser.write function returns before the
character is send, and thus, the DTR line is set too soon. (I checked
this behaivour with an osciloscope).

I thought that seting the writeTimeout parameter could help, but then I
realized that the write function wait "up to this time", so it doesn't
work.

Then I tried waiting some time with time.sleep() after ser.write, but
the shortest time for time.sleep is to big, and non deterministic, so I
think this is not an option.

Does anybody know how to do a ser.write() in a blocking way?

Alejandro.

Take a look at PyMite :

http://www.python.org/pycon/papers/pymite/

 From the abstract :

"PyMite is a flyweight Python interpreter written from scratch to 
execute on 8-bit microcontrollers as well as desktop computers..."

Look at pyParallel (http://pyserial.sourceforge.net/pyparallel.html) 
to control the parallel port. From the parallel port you can control 
external devices. Please note that you will need to add a transistor 
to control a relay.

There is also pySerial, (http://pyserial.sourceforge.net/) to control 
the serial port. If you know how to use a microcontroller (AVR, PIC, 
8031, etc) you can communicate with it through the sereial port, and 
let the micro control the "real world".

Then you add the necesary hand crafted code to the automatic 
generated code. At least is what I did when I needed.

I was in the same shoes a time ago. I started with Tkinter since is 
the standard GUI for Python. I read some tutorials, but didn't go to 
far, and didn't like the Tkinter looks too much. Then I tried 
wxPython, and things were better. And were much better when I started 
using wxGlade.

IMO, wxPython has a softert learning curve (specially if you use 
wxGlade), is portable between unix/windows/mac, with the advantage 
over Tkinter that it has a native look. Regarding documentation, 
there is plenty of it.

I must admit that my background regarding GUIs comes from Delphi, so 
that might bias my opinion.

In case you take the Tkinter route, I founded this tutorial useful :

Try with CRNG, it may have what you need, or be able to adapt it to
what you want. http://www.sbc.su.se/~per/crng/
