Advice needed for Python packaging - can't find required library during installation
Hello all, I am trying to package up a very simple python app. In my setup.py file I have a couple of lines that include the following: from setuptools import setup setup( name='ban', version='0.1', packages=['ban',], description='Python Distribution Utilities', author='Ban', author_email='[email protected]', package_data={'ban': ['data/*.dat']}, long_description=open('README.txt').read(), install_requires=['Google-Safe-Browsing-v2-Lookup'], ) The error I see when running: $> python setup.py install *** running install running bdist_egg running egg_info writing requirements to ban.egg-info/requires.txt writing ban.egg-info/PKG-INFO writing top-level names to ban.egg-info/top_level.txt writing dependency_links to ban.egg-info/dependency_links.txt reading manifest file 'ban.egg-info/SOURCES.txt' writing manifest file 'ban.egg-info/SOURCES.txt' installing library code to build/bdist.linux-x86_64/egg running install_lib running build_py creating build creating build/lib.linux-x86_64-2.6 creating build/lib.linux-x86_64-2.6/ban copying ban/analyzer.py -> build/lib.linux-x86_64-2.6/ban copying ban/__init__.py -> build/lib.linux-x86_64-2.6/ban creating build/bdist.linux-x86_64 creating build/bdist.linux-x86_64/egg creating build/bdist.linux-x86_64/egg/ban copying build/lib.linux-x86_64-2.6/ban/analyzer.py -> build/bdist.linux-x86_64/egg/ban copying build/lib.linux-x86_64-2.6/ban/__init__.py -> build/bdist.linux-x86_64/egg/ban byte-compiling build/bdist.linux-x86_64/egg/ban/analyzer.py to analyzer.pyc byte-compiling build/bdist.linux-x86_64/egg/ban/__init__.py to __init__.pyc creating build/bdist.linux-x86_64/egg/EGG-INFO copying ban.egg-info/PKG-INFO -> build/bdist.linux-x86_64/egg/EGG-INFO copying ban.egg-info/SOURCES.txt -> build/bdist.linux-x86_64/egg/EGG-INFO copying ban.egg-info/dependency_links.txt -> build/bdist.linux-x86_64/egg/EGG-INFO copying ban.egg-info/requires.txt -> build/bdist.linux-x86_64/egg/EGG-INFO copying ban.egg-info/top_level.txt -> build/bdist.linux-x86_64/egg/EGG-INFO zip_safe flag not set; analyzing archive contents... creating dist creating 'dist/ban-0.1-py2.6.egg' and adding 'build/bdist.linux-x86_64/egg' to it removing 'build/bdist.linux-x86_64/egg' (and everything under it) Processing ban-0.1-py2.6.egg removing '/usr/local/lib/python2.6/dist-packages/ban-0.1-py2.6.egg' (and everything under it) creating /usr/local/lib/python2.6/dist-packages/ban-0.1-py2.6.egg Extracting ban-0.1-py2.6.egg to /usr/local/lib/python2.6/dist-packages ban 0.1 is already the active version in easy-install.pth Installed /usr/local/lib/python2.6/dist-packages/ban-0.1-py2.6.egg Processing dependencies for ban==0.1 Searching for Google-Safe-Browsing-v2-Lookup Reading http://pypi.python.org/simple/Google-Safe-Browsing-v2-Lookup/ No local packages or download links found for Google-Safe-Browsing-v2-Lookup error: Could not find suitable distribution for Requirement.parse('Google-Safe-Browsing-v2-Lookup') ** Issue #1 Apparently the setup script cannot find the package - Google-Safe-Browsing-v2-Lookup .

newbie: popen question
hello everyone :-), I am a newbie to python. I am trying to run a bash script from within a python program. I would greatly appreciate any pointers/comments about how to get around the problem I am facing. I want to run bash script: code.sh from within a python program. code.sh needs to be run like so from the command line [code] $ sudo code.sh arg1 arg2 [/code] I read up on some documentation but am not very clear about how to use popen. I want to relegate the shell to a background process, but it needs to accept the sudo passwd too! I have tried [code] p = subprocess.Popen(['/bin/bash', 'sudo '+mypath+'code.sh '+arg1+' '+arg2], stdout=subprocess.PIPE, stderr=subprocess.STDOUT) [/code] I tried some code from stackoverflow.com/questions/694000/why-doesnt- subprocess-popen-always-return nothing really happens when this executes, the PIPE option pshes it to the background and I can't push in the sudo passwd. Can someone please give me an idea of how to go about this. To recap, I want to run a shell script, which needs to be started with sudo, and then push it into the background. Thanks, -A -- http://mail.python.org/mailman/listinfo/python-list

Thanks guys for helping out! very good answers :-)
Before I saw your answers, I tried the following,
output = subprocess.Popen(["sudo","-b", "code.sh", "arg1"],
stdout=subprocess.PIPE).communicate()[0]
This seemed to push the shell execution process to the background and
because my python program was invoked initially with sudo, it seems I
did not need to enter a passwd again.
Any comments about this..any issues that you see will crop up?
Thanks a ton again.

problem with sockets and transferring binary files
Dear all,
I am a python newbie. I am now progressing to writing a
network app in python to learn more about it. I have a client and a
server in python. The client sends a msg to the server asking it to
tar a binary .dbxml file and then send it over to it. The steps are:
from the
1. Client sends msg to server
2. Server tars up binary file and Encrypts it using ezpycrypto
3. Server sends it to client
4. Client receives file and decrypts it and untars it
Surprisingly, the sha1 hash of the encrypted data before it is sent
from server is different from the encrypted file data received by the
client. I post some code below to provide more info about what I am
doing.
[code]
#client after sending initial msg
#get server replywhich sends back the .dbxml file
myHost = '127.0.0.1'
myPort = 20001
s1 = socket(AF_INET, SOCK_STREAM)# create a TCP socket
s1.bind((myHost, myPort))# bind it to the server
port
s1.listen(1) # allow 1 simultaneous
# pending connections
connection, address = s1.accept() # connection is a new socket
while 1:
data = connection.recv(1000) # receive up to 1000
bytes
if data:
info=decryptfile(data)
#we have recieved a compressed .tar.gz file
#write out info to a file
buf = open(currentpath+'received-container.tar.gz', 'w')
buf.write(info)
buf.close()
#testing code: must be removed
os.system('sudo sha1sum '+currentpath+'received-xml-
container.tar.gz')
#uncompress
os.system('sudo tar -xvzf '+currentpath+'received-xml-
container.tar.gz')
[/code]
[code]
#the server after receiving the msg from client
#dump the binary file
os.system('sudo cp '+'/'+path+'1.binary '+currentpath
+'1.binary')
#compress the file
os.system('sudo tar -cvzf '+currentpath+'1.bin.tar.gz
'+currentpath+'1.binary')
#encrypt the file specified in command line
cipher=encryptfile(secretkey, currentpath+'1.bin.tar.gz')
#send it over to sender
send_to_sender(cipher, senderaddress)
#testing code: needs to be removed
buf = open(currentpath+'cipher', 'w')
buf.write(cipher)
buf.close()
os.system('sudo sha1sum '+currentpath+'cipher')
[/code]
[code]
#function code
def send_to_sender(cipher, servername):
PORT = 20001
BUFF = 1000
clientSocket = socket(AF_INET, SOCK_STREAM)
HOST = servername
ADDR = (HOST, PORT)
clientSocket.connect(ADDR)
clientSocket.send(cipher)
clientSocket.close()
[/code]
What I see at the client side is
7105b60d3167f2424d9e2806c49cca86c00577ba received-container.tar.gz
gzip: stdin: unexpected end of file
tar: Unexpected EOF in archive
tar: Unexpected EOF in archive
tar: Error is not recoverable: exiting now
da39a3ee5e6b4b0d3255bfef95601890afd80709 received-container.tar.gz
gzip: stdin: unexpected end of file
tar: Child returned status 1
tar: Error exit delayed from previous errors
It seems two file pieces are received! but why? The buffer size is big
enough to accept the whole thing in one go. The binary file is about
460K in size.
Any pointers, comments will be greatly appreciated :-).
Thanks
