A Logging System for Python
Dear all, I have been looking for a logging system and have come across http://www.red-dove.com/python_logging.html. As the site refers to PEP 282, I assume this package is a potential contender for integration in the Python distribution. Am I correct and if so is there any trend to include it in Python 2.5 ?

http/urlib pos/get question (newbie)
Hi, (I am _very_ new to web programming) I am writing a client module (browser plugin) and server module (Python CGI) that need to exchange information. I want the transaction to be intiated when the client accesses the link. I need data to go back and forth between the client and the server (cgi script) with no impact on what the browser shows. In the end (when I get the above to work), the server will say OK and the actual page will appear or NOK and an ERROR page will appear. I'm pretty clear (I think) as to what to do on the javascript (client) side (XMLHttp) but am not certain if my cgi script must "urlib.open" its own link in order to open the pipe on its side (there'll be some HTML GET/POST tag I assume but where is the pipe/socket ?)

how to modify text in html form from python
Hi,
I am trying to change the data in a form field from python. The following
code does not crash but has no effect as if "form" is just a copy of the
original html form.
Must I recreate the form order to do that ?
My point is for the client to be able to re-read the modified data.
Thanks,
Philippe

import cgi
import os

import cgi

#logging.warning (form)

logging.exception("\nEXCEPTION 1")

Re: how to modify text in html form from python
PS: If my question is not clear, I am trying to "share" the form between the
client and server.
just as many sites out there allow you to modify existing data:
1) the server pops up a form with your data in it.
2) the client can modify it and submit.
I know this is a _basic_ question, sorry.

Thanks Paul but I was not clear: the html page is separate from the python script, it calls the python script when the button is clicked. The indentation error must be because of my cut and paste.

Re: how to modify text in html form from python
Mike,
Here is what I am trying to do:
WHAT
-) a client opens his/her browser and click on some button which triggers my
plugin
-) the plugin starts to communicate with a server on some URL.
-) the communication between the server and the client involves a few
exchanges: data from client to server, then from server to client,.
-) just for info (I do not think it's relevant to my problem) on each side
(server and client) there is a smart card (that's why I need a plugin) and
the information exchanged comes from/go to the smart cards
-) The smart card on the server side eventually decides whether or not the
smart client on the client side is OK and tells so to the cgi script which
acts accordingly
* HOW (if there's a better way let me know please) **
As I have not found any better solution yet, I am trying to do the following
(on the server there is an html file and a cgi file)
-) the plugging opens the correct url which has a form with a "click" button
-) the customer clicks on the button
-) the server "puts" some information in a hidden form field (info from
local smart card)
-) the pluggin fetches the information from the form field and gives it to
its local smart card
... (this a couple of time)
-) the cgi script gets the final verdict from the server smart card and acts
accordingly.
I hope that is clearer.
Regards,
Philippe

I am starting from existing applications (cross-platform - and in python 99% ) that work even through tcp-ip (sockets). I am just trying to apply them to a web environement. So prior to any user interaction with the page, I need some data exchange between the plugin and the server (authentication). So _if_ (I'm a web newbie) the server and the clien(plugin) could exchange data through some form field, my prototype would be much further along.

Re: how to modify text in html form from python
I feel fairly stupid ... but to my defense in the past 17 years of coding, i've only spent 3 days looking at web stuff: I now can understand how "writing" to an existing form field from a cgi script might not work: how would the browser know ?: unless there is a very sophisticated scheme there (as those used in image transfer), I assume the complete page would have to be sent back: so might as well regenerate/rewrite everything. Yes ? I so, I'm back to finding a way for a browser plugin and a server based cgi script to exchange information. Any idea welcome...

Re: how to modify text in html form from python
Paul, That won't cut it: The cards I use/code do not have RSA capabilities but only symmetrical algorithms (AES, 3DES, ). I use the same type of authentication you would see between a POS and a Smart Card (ex: B0' in France) So I cannot hookup to one of the standards (PKCS11 or CSP). Thanks anyway.

SCWEB 0.1 to be released
Dear all, I intend to release withing the next very few week the version 0.1 of SCWEB, a cross-platform web authentication platform _mostly_ written in Python and adaptable to most programming languages. SCWEB will come with server modules (cgi), client modules (Firefox extension/plugin and XPCOM modules) All modules are operational except for the XPCOM part. I whised to announce the coming SCWEB now because I have opened a blog (www.snakecard.com/WordPress) so I might potentially get important feedback prior to the release. SCWEB will be distributed under the GPL license. Comments are quite welcome: www.snakecard.com/WordPress Regards, Philippe Martin -- http://mail.python.org/mailman/listinfo/python-list

getting there, this sequence creates a file with the correct uid and gid

Crash in python while run from U3 device
Hi,
I am currently porting some of my applications to U3 (www.u3.com) and I do
get a crash in ...objects\frameobject.c: PyFrameObject *back =
tstate->frame.
The point of the current test is to get a python function called on a U3
device event. (U3 only work with Windows currently).
My C stub callback does get called but crashes when it tries to call the
python function.
***
This is the function that registers the callback (actual dll prototype in
header):
***
static PyObject *s_callback=NULL;
/**/
/**/
/* HRESULT dapiRegisterCallback( HSESSION hSession ,wchar_t*
pszConnectionString ,DAPI_CALLBACK pCallBack,void* pEx ,HCALLBACK*
hCallback) */
/**/
/**/
static PyObject *Py_dapiRegisterCallback(PyObject *p_self, PyObject *p_args)
{
HRESULT l_result;
HSESSION l_hSession;
wchar_t* l_pszConnectionString;
PyObject *l_tmp_cb;
//PyObject cs;
void* l_pEx;
HCALLBACK l_hCallback;
if
(!PyArg_ParseTuple(p_args,"iuOi",&l_hSession,&l_pszConnectionString,&l_tmp_cb,&l_pEx)
)
{
BAD_PARAM;
return NULL;
}
//l_pszConnectionString = PyObject_Unicode(cs);
Py_XINCREF(l_tmp_cb);
Py_XDECREF(s_callback);
s_callback=l_tmp_cb;
l_result =
dapiRegisterCallback(l_hSession,l_pszConnectionString,Stub_Callback,l_pEx,&l_hCallback);
CHECK_RESULT;
return Py_BuildValue("l",l_hCallback);
}
***
This is the stub callback that crashes:
***
void _stdcall Stub_Callback(HDEVICE p_dev, DWORD p_event, void *p_pEx)
{
PyObject *l_result;
PyObject *l_arg_list;
l_arg_list = Py_BuildValue("(iii)", p_dev,p_event,p_pEx);
l_result = PyEval_CallObject(s_callback, l_arg_list); /*No crash if I
comment this line*/
Py_DECREF(l_arg_list);
}
*
This is the python source
*
(cs, and s have a correct value ... I think )
import u3
def mf(a,b,c):
print 'CB'
h=u3.dapiRegisterCallback(s, cs, mf, 0)
Any help _greatly_ appreciated.
Regards,
Philippe

shelve seg error
Hi,
I just installed (compiled) Python 2.4.2 under Suse 10.

Tkinter: passing parameters to menu commands
Hi, I have he following need and do not find an easy way out: I have many menu items and would like them all to call the same method -However, I need the method called to react differently depending on the menu item selected. Since the menu command functions do not seem to receive any type of event style object, is there some type of Tkinter call that would let my method know the menu id selected ? Philippe -- *** Philippe C. Martin SnakeCard LLC www.snakecard.com *** -- http://mail.python.org/mailman/listinfo/python-list
Re: Tkinter: passing parameters to menu commands
>>menu.add_cascade(label="File", menu=filemenu)
>>filemenu.add_command(label="New", command=lambda: callback('New'))
>>filemenu.add_command(label="Open...", command=lambda:
callback('Open'))
>>filemenu.add_separator()
>>filemenu.add_command(label="Exit", command=lambda: callback('Exit'))
mainloop()
>>Of course you could do this with named forwarding functions if you

I'm not sure what 'named forwarding functions' are but I'm actually in a
class and when applying your suggestion in the following manner,
everything works (THANKS!)
def __Dec(self,p_string):
for i in p_string:
self.__Insert(i)
.
.
.
#menu creation
l_dec.add_command(label = 'ATR', command=lambda: self.__Dec('ATR'))
l_dec.add_command(label = 'IN', command=lambda:self.__Dec('IN'))
.
.
.
Yet I have a question:
If I replace the menu creation code as below, and since __Insert appends
the string p_string into a text widget that is created _after_ the menu
creation; the method __Dec seems to be called at the menu creation and
I get an error in __Insert because the test widget is equal to None.
My reflexes of C programmer tell me that command=self.__Dec just
passes a method pointer (sorry I said it) to add_command - yet it does
not seem to be so.
What is actually going on ?
#menu creation
l_dec.add_command(label = 'ATR', command=self.__Dec('ATR'))
l_dec.add_command(label = 'IN', command=self.__Dec('IN'))

Re: What's the best python web-developer's editor
>>Emacs >>For both discrete and mixed python and html code, and why? >>There's no reason to use anything else. Although I tested and will keep testing other editors/ide, I also went back to emacs and am quite happy with it. However, I sometimes use snavigator (http://sourceforge.net/projects/sourcenav) when I need to browse through a project (although I could use emacs TAGS, I find snavigator to be the best free solution out there to parse large projects) Regards, Philippe -- ******* Philippe C.

Re: What is print? A function?
Why don't you redirect stdout or stderr #*** class Debug_Stderr: __m_text = '' __m_log_text = None __m_dbg = None __m_refresh_count = 0 #*** def __init__(self): #*** def write(self,p_string): #your code here . . . my_debug = Debug_Stderr() sys.stderr = my_debug print >> sys.stderr, 'this will go into the above write method' -- ******* Philippe C.

RE:"private" variables a.k.a. name mangling (WAS: What is print? A function?)
I use "__"for private variables because I must have read on net it was the way to do so - yet this seems to have changed - thanks: http://www.network-theory.co.uk/docs/pytut/tut_77.html As far as the specific stderr reroute example - I just grabbed some of my code and forgot to get rid of that stuff Regards, Philippe -- *** Philippe C.

RE: Why I use private variables (WAS: RE:"private" variables a.k.a. name mangling?)
The real reason behind my using private variables is so they do not appear in the epydoc generated documentation and confuse my users. Regards, Philippe -- *** Philippe C. Martin SnakeCard LLC www.snakecard.com *** -- http://mail.python.org/mailman/listinfo/python-list
RE: Why I use private variables (WAS: RE:"private" variables a.k.a. name mangling?)
I used double underscore because I thought it was the correct way to name private variables/methods - I will have to change those to single underscore since that it the current methodology. A private variable to me: 1) is internal to the processing of a class and needs not be accessed by external or derivated objects. (I won't get into the potential need of "protected" variables/methods - Python creators have not made those distinctions for reasons that they believe are good and I'm not the one to discuss them) 2) Must not be documented to library users as they're using it would go againts 'law' 1). 3) I wish I had one, but there is only one Isaac Asimov after all :-) Regards, Philippe On Mon, 24 Jan 2005 11:45:34 -0500, Jeremy Bowers wrote: > On Mon, 24 Jan 2005 15:35:11 -0600, Philippe C.
