#
# It's often suggested that the SIGHUP signal should be ignored before
# the second fork to avoid premature termination of the process. The
# reason is that when the first child terminates, all processes, e.g.
# the second child, in the orphaned group will be sent a SIGHUP.
#
# "However, as part of the session management system, there are exactly
# two cases where SIGHUP is sent on the death of a process:
#
# 1) When the process that dies is the session leader of a session that
# is attached to a terminal device, SIGHUP is sent to all processes
# in the foreground process group of that terminal device.
# 2) When the death of a process causes a process group to become
# orphaned, and one or more processes in the orphaned group are
# stopped, then SIGHUP and SIGCONT are sent to all members of the
# orphaned group." [2]
#
# The first case can be ignored since the child is guaranteed not to have
# a controlling terminal. The second case isn't so easy to dismiss.
# The process group is orphaned when the first child terminates and
# POSIX.1 requires that every STOPPED process in an orphaned process
# group be sent a SIGHUP signal followed by a SIGCONT signal. Since the
# second child is not STOPPED though, we can safely forego ignoring the
# SIGHUP signal. In any case, there are no ill-effects if it is ignored.

"""
BitBake 'Data' implementations
Functions for interacting with the data structure used by the
BitBake build tools.
The expandData and update_data are the most expensive
operations. At night the cookie monster came by and
suggested 'give me cookies on setting the variables and
things will work out'. Taking this suggestion into account
applying the skills from the not yet passed 'Entwurf und
Analyse von Algorithmen' lecture and the cookie
monster seems to be right. We will track setVar more carefully
to have faster update_data and expandKeys operations.
This is a treade-off between speed and memory again but
the speed is more critical here.

BitBake 'Fetch' implementations
This implementation is for Secure Shell (SSH), and attempts to comply with the
IETF secsh internet draft:
http://tools.ietf.org/wg/secsh/draft-ietf-secsh-scp-sftp-ssh-uri/
Currently does not support the sftp parameters, as this uses scp
Also does not support the 'fingerprint' connection parameter.

We have the following windows:
1.) Main Window: Shows what we are ultimately building and how far we are. Includes status bar
2.) Thread Activity Window: Shows one status line for every concurrent bitbake thread.
3.) Command Line Window: Contains an interactive command line where you can interact w/ Bitbake.
Basic window layout is like that:

"""
This module implements an xmlrpc server for BitBake.
Use this by deriving a class from BitBakeXMLRPCServer and then adding
methods which you want to "export" via XMLRPC. If the methods have the
prefix xmlrpc_, then registering those function will happen automatically,
if not, you need to call register_function.
Use register_idle_function() to add a function which the xmlrpc server
calls from within server_forever when no requests are pending. Make sure
that those functions are non-blocking or else you will introduce latency
in the server's main loop.
