# The main() function has been replaced by a whole class, in order to
|
|
# address the constraint that only one process can sit on the port
|
|
# hard-coded into the loader.
|
|
|
|
# It attempts to load the RPC protocol server and publish itself. If
|
|
# that fails, it assumes that some other copy of IDLE is already running
|
|
# on the port and attempts to contact it. It then uses the RPC mechanism
|
|
# to ask that copy to do whatever it was instructed (via the command
|
|
# line) to do. (Think netscape -remote). The handling of command line
|
|
# arguments for remotes is still very incomplete.
|
|
|
|
# Default behavior (no command line options) is to open an editor window
|
|
# instead of starting the Python Shell. However, if called as
|
|
# Pyshell.main(0), the Shell will be started instead of the editor window.
|
|
|
|
# In the default editor mode, if files are specified, they are opened.
|
|
|
|
# If any command line options are specified, a shell does appear, and if
|
|
# the -e option is used, both a shell and an editor window open.

IDLE needs to use a specific TCP/IP port (7454) in order to execute and

debug programs. IDLE is unable to bind to this port, and so cannot

|
start. Here are some possible causes of this problem:

1. TCP/IP networking is not installed or not working on this computer
|
|
2. Another program is running that uses this port

3. Another copy of IDLE stopped responding but is still bound to the port

|
4. Personal firewall software is preventing IDLE from using this port

|
|
|
IDLE makes and accepts connections only with this computer, and does not
|
|
communicate over the internet in any way. It's use of port 7454 should not

be a security risk on a single-user machine.
