Real handling of network errors.
Fix for correctly ignoring net errors: It seems that (at least in
my installed Debian version of python2.4) socket.error does not have an
errno attribute but is simply a tuple of (errno, strerror). So we now
try to get errno first and if this fails we try to use err [0]. This
works for a simple test-script to which I can connect with telnet on
port 4711 -- it will correctly detect errno.EPIPE if I terminate the
telnet session:
#!/usr/bin/python2.4
import socket
import errno
from SocketServer import TCPServer, BaseRequestHandler
class Server (BaseRequestHandler) :
def handle (self) :
self.file = self.request.makefile ()
try :
while True :
print >> self.file, "Testing..."
except socket.error, err :
print getattr (err, 'errno', "Has no errno")
print err [0]
print err [0] == errno.EPIPE
raise
# end def handle
# end class Server
server_address = ('', 4711)
s = TCPServer (server_address, Server)
s.serve_forever ()
Sorry for the verbose log-message but I hope to document my debugging
activities

This is a simple-to-use and -install issue-tracking system with command-line, web and e-mail interfaces. Roundup manages a number of issues (with properties such as "description", "priority", and so on) and provides the ability to (a) submit new issues, (b) find and edit existing issues, and (c) discuss issues with other participants. The system will facilitate communication among the participants by managing discussions and notifying interested parties when issues are edited. Roundup's structure is that of a cake:: _________________________________________________________________________ | E-mail Client | Web Browser | Detector Scripts | Shell | |------------------+-----------------+----------------------+-------------| | E-mail User | Web User | Detector | Command | |-------------------------------------------------------------------------| | Roundup Database Layer | |-------------------------------------------------------------------------| | Hyperdatabase Layer | |-------------------------------------------------------------------------| | Storage Layer | ------------------------------------------------------------------------- 1. The first layer represents the users (chocolate). 2. The second layer is the Roundup interface to the users (vanilla). 3. The third and fourth layers are the internal Roundup database storage mechanisms (strawberry). 4. The final, lowest layer is the underlying database storage (rum). These are implemented in the code in the following manner:: E-mail User: roundup-mailgw and roundup.mailgw Web User: cgi-bin/roundup.cgi or roundup-server over roundup.cgi.client and roundup.cgi.template Detector: roundup.roundupdb and templates/<template>/detectors Command: roundup-admin Roundup DB: roundup.roundupdb Hyper DB: roundup.hyperdb, roundup.date Storage: roundup.backends.* Additionally, there is a directory of unit tests in "test". For more information, see the original overview and specification documents written by Ka-Ping Yee in the "doc" directory. If nothing else, it has a much prettier cake :) ''' __docformat__ = 'restructuredtext' __version__ = '1.3.2' # vim: set filetype=python ts=4 sw=4 et si
