shelve seg error
Hi,
I just installed (compiled) Python 2.4.2 under Suse 10.
The following code generates a seg error:
import shelve
print shelve.open ('test')
I assume this has to do with the db behind shelve.
How do I go about tracing/fixing the problem ?

many pins as 0's or 1's but should it be that hard to do with python.
I've looked through how python does serial with the serial module but
it just uses Java's javax.comm libraries. Is there anyway to do very
low level device writing to COM ports?
In summary I'm looking for something like:
ser = serial.Serial(0)
ser.pin0 = 1
ser.pin1 = 1
ser.pin2 = 1
or
ser.write('0xFF')
which would set 8 pins on the RS232 cable to 1's

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

My C stub callback does get called but crashes when it tries to call the
python function.

Re: user account logon from python
Hi Mike,
Mike Meyer wrote:
1- I cannot find getpwent in the documentation
getpwent is a Unix library call. For python, you want the pwd
module. The docs are URL: http://docs.python.org/lib/module-pwd.html .
I must be blind but still do not see it - do you mean getpwnam ?
2- crypt will not work if the system does not have shadow pw
Rubbish. crypt doesn't know anything about passord files. It just
knows how to encrypt a password. It's up to you to get the password
attempt from the user, and the encrypted password from the password
file (or the shadow password file). The pwd module doesn't deal with
shadow passwords. Maybe you meant system does have shadow pw. But
it's pwd that doesn't work, not crypt - and that depends on the
system. For instance:
I meant that the code form the documentation fails on the raise, with the
error Sorry, currently no support for shadow passwords
What should I understand ?
import os
import crypt, getpass, pwd
def login():
username = raw_input('Python login: ')
cryptedpasswd = pwd.getpwnam(username)[1]
print cryptedpasswd
if cryptedpasswd:
if cryptedpasswd == 'x' or cryptedpasswd == '*':
raise Sorry, currently no support for shadow passwords
cleartext = getpass.getpass()
return crypt.crypt(cleartext, cryptedpasswd) == cryptedpasswd
else:
return 1
bhuda% cat tp.py
#!/usr/bin/env python
import pwd, os
p = pwd.getpwnam(os.environ['USER'])
print p[1]
bhuda% ./tp.py
*
But:
bhuda# ./tp.py
$1$cKJbUtaY$y.e7GRjo8ePxgiBzskyRX0
I.e. - as me, the pwd routines won't return passwords. As root, it
returns the encrypted password.
3- Even as root I get Operation not permitted using setuid and setgid
... but I assume it is because I cannot get 1 and/or 2 to work.
They shouldn't have anything to do with it. Are you sure the process
is running as root? For instance, most modern Unices won't honor the
the setuid bit on script executables. You have to write a setuidj
wrapper that runs the interpreter with the appropriate privileges.

Thanks and regards,

Tkinter and X11
Hi, Is there anything that prevents tkinter from running prior to login to an X11 session: as the X server is already up ? Regards, Philippe -- http://mail.python.org/mailman/listinfo/python-list
Re: Tkinter and X11
Thanks jeff, I actually want that Tkinter application to be the greater: replace gdm Still feasible as far as Tkinter is conserned ? Thanks and regards, Philippe [EMAIL PROTECTED] wrote: There should be no problem with this. After all, even the greeter is just an X application. Depending on which login manager you use (xdm/kdm/gdm/whatever) the details of getting your Tkinter app to actually be run will vary, though. In gdm, it looks like adding it to the file /etc/X11/gdm/Init/default may be the ticket. It is probably best to run app.tk.call(rename, send, ) in your program, for the reasons outlined in the send(n) manpage: SECURITY The send command is potentially a serious security loophole. On Unix, any application that can connect to your X server can send scripts to your applications. These incoming scripts can use Tcl to read and write your files and invoke subprocesses under your name. Jeff -- http://mail.python.org/mailman/listinfo/python-list

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, ).

The major browsers already have smart card interfaces (Windows CAPI for MSIE, or PKCS11 for Netscape/Moz*) so you shouldn't need a plugin. On the other hand, smart cards are very slow. The typical approach is as follows (MSIE version). Stop using special smart card programs and just use a card that implements CAPI with a from the vendor and that can sign against an X509 certificate. The CSP will have a special signature that makes it less scary to install than a browser plugin. You'll have to issue a cert for the smart card and there's various approaches to that, so I'll skip that part. Set up a TLS server to require a client cert from the CA that signed the smart card. The browser should recognize the challenge and select the right cert. The CSP will have its own interface for the user entering a PIN along with inserting the card. Once you have the TLS connection established, set a secure cookie in the client session and then redirect the browser to another URL that doesn't require the smart card (because otherwise the card will have to re-authenticate every click, which is very slow). From then on, use the cookie for authentication (it can have a timeout or whatever). -- http://mail.python.org/mailman/listinfo/python-list

Well not in this case actually: the user triggers the plugin which in turn open the url, so the connection is owned by the plugin That won't work very well. HTML goes to the client to display. The server can put data in hidden form elements that code running on the client side can get to - and change - via the document object model (DOM). However, the only way to send the changed data back to the server is to get the client to submit the form. You can automate that, but the results will be disconcerting to the user: they load a page, and it reloads multiple times as the plugin exchanges data with the server. Here again, I'm not dying for any page data to be visible: cannot the cgi script and the plugin do their business before that ? The problem with this is that the apache-browser connection isn't a connection, it's a series of HTTP request/repsonse pairs. Originally, this implied tearing down and setting up a TCP connection for every request. Modern software will leave the link open and reuse it - but modern software also tends to have multiple connetions open, so it can fetch images and other embedded objects in parallel. I'm lost here, better do some more reading You can make this work, but doing it like that requires making multiple HTTP requests via the browser, which will be disconcerting. I'd recommend taking the browser out of the loop. Have the plugin talk directly to the server to do the authentication. That's what the latest web buzzword (AJAX) does: client-side software makes independent requests of the server (or *any* server) to get data, and possibly updates the document the browser is viewing as a result of that. Here I think it's OK as the plugin can talk to server prior to the browser showing anything. So here's a scenario: the first cgi script gets info from the smart card that puts it in a hidden form element and sends the page to the browser. The plugin - started when the page loads - uses the DOM to get that data, then makes an *independent* HTTP request to the server, thus passing whatever it generated from the data in the form field to a second cgi script. This happens several times, then the plugin changes the HTML form to put whatever the cgi script generated into the form, so that when the user finally submits the form, the third cgi script - the one that handles the submitted form - sees the data from the second script. Actually, the exchanges between the plugin and the server don't need to be HTTP requests. If you've got this working over some other TCP protocol, there's no reason you can't keep doing it that way. Maybe that's my clue: can a cgi script, once triggered by a (let's say) POST request, use back and forth file transfer with the client ? through the _existing_ connection. A word of warning: authentication protocols are fragile; they tend to stop being resistant to attacks after even relatively minor changes, so you want to be very carefull about changing the protocol. Web-based things are very open. You can't really do much to prevent the client end from doing *whatever they want* with the HTML you send them, or you generate for them on the fly. This also has serious security implications. Think carefully about what happens when the user pulls one of your forms out of the browser history, or bookmarks a page. Then make sure you get a thorough audit of the resulting system/protocol done by people who know what they're doing. Even if the data when seen, there would not be any security breach as the cards have the keys + algo to understand the data.

Well not in this case actually: the user triggers the plugin which in turn open the url, so the connection is owned by the plugin I think we don't mean the same thing when we say plugin. To me, a plugin is a bit of code that gets executed when the page is rendered to provide custom content with it's own behavior. Flash is probably the most popular example. Like I said, I don't know much about plugins, so they may be usable in other ways. That won't work very well. HTML goes to the client to display.

Modern software will leave the link open and reuse it - but modern software also tends to have multiple connetions open, so it can fetch images and other embedded objects in parallel. I'm lost here, better do some more reading HTTP is a stateless protocol. Every HTTP request goes the same: the client sends a request saying what object it wants from the server. The server reads the request, and sends back the response, which is a collection of HTTP headers and a string of bytes. There's lots more details invovled, and various things you can do to enhance the performance of the system, but functionally they all boil down to that. You can make this work, but doing it like that requires making multiple HTTP requests via the browser, which will be disconcerting. I'd recommend taking the browser out of the loop. Have the plugin talk directly to the server to do the authentication. That's what the latest web buzzword (AJAX) does: client-side software makes independent requests of the server (or *any* server) to get data, and possibly updates the document the browser is viewing as a result of that. Here I think it's OK as the plugin can talk to server prior to the browser showing anything. If you say so. But certainly not through the browser. So here's a scenario: the first cgi script gets info from the smart card that puts it in a hidden form element and sends the page to the browser. The plugin - started when the page loads - uses the DOM to get that data, then makes an *independent* HTTP request to the server, thus passing whatever it generated from the data in the form field to a second cgi script. This happens several times, then the plugin changes the HTML form to put whatever the cgi script generated into the form, so that when the user finally submits the form, the third cgi script - the one that handles the submitted form - sees the data from the second script. Actually, the exchanges between the plugin and the server don't need to be HTTP requests. If you've got this working over some other TCP protocol, there's no reason you can't keep doing it that way. Maybe that's my clue: can a cgi script, once triggered by a (let's say) POST request, use back and forth file transfer with the client ? through the _existing_ connection. I honestly don't know. HTTP does a strict onetime turnaround - the client sends, then the server sends, then you're done. There are hooks in the protocol to allow a connection to be resused, but that's a different request/response pair, and generally handled by the server, not the cgi script. After all, the next request from the client may be for some static file instead of the output of a cgi script. Having a cgi script start two
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 ?)

Re: How to protect Python source from modification
Hi, Why not just releasing the *.pyc ? Regards, Philippe Frank Millman wrote: Hi all I am writing a multi-user accounting/business system. Data is stored in a database (PostgreSQL on Linux, SQL Server on Windows). I have written a Python program to run on the client, which uses wxPython as a gui, and connects to the database via TCP/IP. The client program contains all the authentication and business logic. It has dawned on me that anyone can bypass this by modifying the program. As it is written in Python, with source available, this would be quite easy. My target market extends well up into the mid-range, but I do not think that any CFO would contemplate using a program that is so open to manipulation. The only truly secure solution I can think of would involve a radical reorganisation of my program, so I am writing to see if anyone has a simpler suggestion. Here is the idea. 1. Write a socket server program that runs on the server. The socket server is the only program that connects to the database. The client program connects to the server, which authenticates the client against the database and then listens for requests from the client. 2. Devise my own protocol for communication between client and server. For selects, the client sends a request, the server checks permissions, then retrieves the data from the database and passes it to the client. For updates, the client passes up the data to be updated, the server checks it against its business logic, and then updates the database. There is the question of where state should be maintained. If on the server, I would have to keep all the client/server connections open, and maintain the state of all the sessions, which would put quite a load on the server. If on the client, I would have to reorganise my thinking even more, but this would have an advantage - I will eventually want to write a browser interface, and this would be much closer in concept, so the two approaches would be quite similar. This raises the question of whether I should even bother with a gui client, or bite the bullet and only have a browser based front end. Judging from recent comments about new technologies such as Ajax, a lot of the disadvantages have been overcome, so maybe this is the way to go. It would be a shame to scrap all the effort I have put into my wxPython-based front end. On the other hand, it would be pointless to continue with an approach that is never going to give me what I want. Any advice which helps to clarify my thinking will be much appreciated.

pywin32 com server cash question
Hi,
I just got the pywin32 hello world COM server to install and I did manage
to use it from VB 6.0.
However, there are some glitches I do not comprehend:
1) at one point I got a python runtime error telling me the testcomserver
was not found - I got rid of that problem by deleteting the appropriate (I
hope) registry and reregistering the server
2) If I change the source of the server
from:
return Hello +
to:
return Hello my friend +
I still get Hello BINGO only in my VB message box. this even if I try to
re-register (which does not seem necessary) the server.
Q.1) What could that error have meant ?
Q.2) is there a way to flush whatever so my new code Hello my friend
shows up ?
The VB looks like this:
Private Sub Command1_Click()
Dim shdemo = CreateObject(Python.TestServer)
MsgBox (shdemo.Hello(BINGO))
End Sub
The Python server :
class HelloWorld:
_reg_clsid_ = {7CC9F362-486D-11D1-BB48-E838A65F}
_reg_desc_ = Python Test COM Server
_reg_progid_ = Python.TestServer
_public_methods_ = ['Hello']
_public_attrs_ = ['softspace', 'noCalls']
_readonly_attrs_ = ['noCalls']
#_reg_class_spec_ = testcomserver.HelloWorld
def __init__(self):
self.softspace = 1
self.noCalls = 0
def Hello(self, who):
self.noCalls = self.noCalls + 1
# insert softspace number of spaces
return Hello My Friend + * self.softspace + str(who)
if __name__=='__main__':
# ni only for 1.4!
