e.g. further improve subprocess interrupt, exceptions, and termination.
2. Remove the workarounds in PyShell.py and ScriptBinding.py involving
interrupting the subprocess prior to killing it, not necessary anymore.
3. Fix a bug introduced at PyShell Rev 1.66: was getting extra shell menu
every time the shell window was recreated.

sys.path, prepend it. This allows the module to import other modules
in the same directory. Do the same for a script run from the command
line.
2. Tweak the IDLE usage message a bit more.

2. Remove the shell menu and associated bindings when running
without the subprocess.
3. Update the IDLE Help and usage text.
4. Update display_port_binding_error to suggest using -n

2. Add an indicator to the shell startup notice when running w/o
subprocess.
3. Improve exception reporting when running a command or script from the
command line.
4. Clarify the fact that breakpoints set or cleared after a file is
saved will revert to the saved state if the file is closed without
re-saving.
5. If user tries to exit or restart when user code is running, interrupt
the user code. This helps to eliminate occasional hanging
subprocesses on Windows (except for Freddy :).

2. Tweak signal.signal() wait parameters as called by various methods
to improve I/O response, especially on Windows.
3. Debugger is disabled at this check-in pending further development.

1. Move subprocess socket handling to a subthread - "SockThread".
2. In the subprocess, implement a queue and global completion and exit
flags. Execute code after it is passed through the queue. (Currently,
user code is executed in SockThread. The next phase of development will
move the tail of the queue to MainThread.)
3. Implement an RPC message used to shut down the execution server.
4. Improve normal and exception subprocess exits.
(At this checkin a "pass loop" interrupt doesn't work on any platform. It
will be restored for all platforms once user code execution is moved to
MainThread.)

Clean up the way IDLEfork handles termination of the subprocess, restore
ability to interrupt user code in Windows (so long as it's doing terminal
I/O).
1. Handle subprocess interrupts in Windows with an RPC message.
2. Run/F5 will restart the subprocess even if user code is running.
3. Restart the subprocess if the link is dropped.
4. Exit IDLE cleanly even during I/O.
4. In rpc.py, remove explicit calls to statelock, let the condition
variable handle acquire() and release().
M rpc.py
SF Bug 676398 Doesn't handle non-built-in exceptions
1. Move exception formatting to the subprocess; allows subclassing of
exceptions, including subclasses created in the shell without
introducing excessive complexity in the RPC mechanism.
2. Provide access to linecache from subprocess to support this.
M RemoteDebugger.py
M rpc.py
Fix the incorrect shell exception tracebacks generated when running
under debugger control:
1. Use rpc.SocketIO.asynccall() instead of remotecall() to handle the
IdbProxy.run() command.
2. Add a 'shell' attribute to RemoteDebugger.IdbProxy to allow setting
of ModifiedInterpreter's active_seq attribute from RemoteDebugger code.
3. Cleanup PyShell.ModifiedInterpreter.runcode() and remove ambiguity
regarding use of begin/endexecuting().
4. In runcode() and cleanup_traceback() use 'console' instead of 'file' to
denote the entity to which the exception traceback is printed.
5. Enhance cleanup_traceback() so if the traceback is pruned entirely away
(the error is in IDLE internals) it will be displayed in its entirety
instead.
6. ModifiedInterpreter.runcode() now prints ERROR RPC returns to both
console and __stderr__.
7. Make a small tweak to the rpc.py debug messages.

1. Clear any un-entered characters from input line before printing the
restart boundary.
2. Restore the Debug menu: There are now both Shell and Debug menus.
3. Add Control-F6 keybinding to Restart Shell.
4. Clarify PyShell.cancel_check() comment.
5. Update doc string for Bindings.py and re-format the file slightly.

1. Annotate the shell window with last restart boundary upon restart.
2. Provide a shell menu entry and hot key (F6) to jump to the last
restart boundary.
3. Add a new shell menu feature to restart the shell.
4. Update the help menu to add these features.
5. Update the help menu to put text in same order as the menus.
6. Correct a capitalization inconsistency on the Edit menu: Expand Word
7. Rename the "Debug" menu to be "Shell": it's doing more now.
8. Rearrange the "Shell" menu to make the StackViewer entries adjacent.
9. Add a get_geometry method to EditorWindow, which may be of use in
making window positions persisent.
10. Make <ctrl-v> the "Classic Windows" paste key.
11. Restore decorum on the Help menu by removing "Advice". As Guido said,
things will never be the same. Thanks, David!
M PyShell.py
1. PyShell Rev 1.39, EditorWindow Rev 1.37 fix was not handling a
multiline prompt.
2. The same fix introduced a bug where hitting <enter> at a previous
prompt-only line would copy the prompt to the iomark.
3. Move the setting of sys.ps1 earlier, into PyShell.main(), to allow
this code to work before a shell is started up.
4. If cursor is on the input line in the prompt, and you hit <enter>,
process the line instead of complaining.
5. If line has no stdin range (this includes the last line before shell
restart) strip any prompt before recalling.

Switch back to installing IDLE as a package. The IDLE GUI and the
subprocess will both attempt to start up via the package mechanism, but if
IDLE is not yet installed it is possible to run by calling python idle.py
in the IDLE source directory, or to add the source directory to sys.path.
One advantage of doing it this way is IDLE stays off sys.path.
Developed in collaboration with Tony Lownds.
