This bug, henceforth designated Freddy, was due to the mistaken
elimination of the KeyboardInterrupt exception at the previous revision.
PyShell's unix_terminate hammer was masking the problem on Linux. On W2K
the subprocess MainThread was trying to print the exception after the
SockThread had ceased to service the socket. The subprocess would then
detach and spin when the GUI created the new subprocess.
Modified Files: run.py
2. run.py: move exception printing to toplevel to allow access from main()

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.)

1. Clarify that rpc.SocketIO._getresponse() currently blocks on socket.
2. Improve exception handling in subprocess when GUI terminates abruptly.

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().

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.

- Removed the File Path from the Additional Help Sources scrolled list.
- Add capability to access Additional Help Sources on the web if the
Help File Path begins with //http or www. (Otherwise local path is
validated, as before.)
- Additional Help Sources were not being posted on the Help menu in the
order entered. Implement sorting the list by [HelpFiles] 'option'
number.
- Add Browse button to New Help Source dialog. Arrange to start in
Python/Doc if platform is Windows, otherwise start in current directory.
- Put the Additional Help Sources directly on the Help menu instead of in
an Extra Help cascade menu. Rearrange the Help menu so the Additional
Help Sources come last. Update help.txt appropriately.

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

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.

M setup.py
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.

M PyShell.py
M idlever.py
M setup.py
1. Update MANIFEST.in to include all non-pure Python files
2. PyShell and idlever reflect Rev 0.9a0
3. setup.py modified to install IDLE as a collection of modules with
a .pth file living at the idlelib level in site-packages. This was
done to make it easier to run from the source directory prior to
installing IDLE. This approach may change back to the package
technique depending on what happens with the Mac installation
development.

IDLE was called.
Insert the current working directory in the path if it isn't there
already.
M idle
M setup.py
To be able to run from the source directory or from an installed version
of IDLE, and also to allow the subprocess to find run(), Python needs to
have the idlelib package on its path.
1. Modify setup.py to supply a .pth file living at same level as idlelib
2. Move boolcheck to PyShell.py
3. Remove boolcheck and path setting code from the "idle" script
1. Make it easier to change the package and script installation names.
2. Update the text files transferred to include the .def and new .txt
files.
3. Update the description and long description, change email to
python-dev, update the url to point at sourceforge.
4. Rename the build and install classes for clarity.
Another applet mechanism has been developed for Python on Mac OS X and
trying to use the -c "__import__('run').main()" trick is just not working.
macosx_main.py is a new file which should be used as the startup file for
Mac OS X applet bundles. This startup file understands a -p option, which
when seen will start run.main(). When running as an applet, this seems like
the best approach.

1. Update ScriptBinding.py to highlight a syntax error in the Edit window,
and place the cursor on the error. Add a syntax check to the
Run Script event instead of waiting until the script tries to run and
raises a syntax error in the shell, forcing the user to navigate back
to the Edit window to fix it.

M PyShell.py
* Could not remove last set of saved breakpoints from a file
* Starting with empty edit window, could not load a file
* Multiple adjacent breakpoints were saved as one breakpoint
* Storing breakpoints whenever a file is closed can get them out
of synch with the saved version of a file. Only store them when the
file is saved.
* Add comment on current limitations on file editing in the presence of
breakpoints.
* Replace get_current_breaks() with update_breakpoints(), add an update to
PyShellEditorWindow.breakpoints, which is the master breakpoint data
structure, and which is used to reload the subprocess debugger.
* Revert Debugger.Debugger.load_breakpoints() to use editwin.breakpoints.
It is easier to debug the debugger if the breakpoint list in IDLE is
identical to the list in the subprocess debugger and is transferred when
the subprocess debugger is restarted, because this list can be easily
queried.
* Cleanup some linespacing and comments in IOBinding.py
M CallTips.py
Calltip fetch was erroring when an Edit window was used without a Shell.

5. Pass string exception arg as a string rather than a tuple.

Rev 1.6 gvanrossum
(partially merged previously, move line outside try: block)
Provisional fix for writefile() [SF bug # 541730].
The problem was that an exception can occur in the text.get() call or
in the write() call, when the text buffer contains non-ASCII
characters. This causes the previous contents of the file to be lost.
The provisional fix is to call str(self.text.get(...)) *before*
opening the file, so that if the exception occurs, we never open the
file.
Two orthogonal better solutions have to wait for policy decisions:
1. We could try to encode the data as Latin-1 or as UTF-8; but that
would require IDLE to grow a notion of file encoding which requires
more thought.
2. We could make backups before overwriting a file. This requires
more thought because it needs to be fast and cross-platform and
configurable.

Restart the execution server with a clean environment and execute the
active module from scratch upon activation of Run/F5.
Add functionality to PyShell.py to restart the execution server in a new

block of code to be executed.
Modify ScriptBinding.py to restart the subprocess upon Run/F5, assuming that
an execution is not currently in progress. Remove Import Module functionality,
not required now that the code is executed in a clean environment.
If the Debugger is active, also restart the subprocess side of the split
debugger. Add functionality to RemoteDebugger.py to support this.
At this time breakpoints will be lost in the subprocess if Run/F5 is activated.
A subsequent checkin of PyShell.py will implement reloading of the breakpoints
into the subprocess debugger. I'm keeping this separate as the design may
change.

idles: Removed the idles script, not needed
******************

Added a patch which modifies idlefork so that it can co-exist with
"official" IDLE in the site-packages directory. This patch is not
necessary if only idlefork IDLE is installed. See INSTALLATION for further
details.
The default behaviour of idlefork idle is to open an editor window instead
of a shell. Complex expressions may be run in a fresh environment by
selecting "run". There are times, however, when a shell is desired.
Though one can be started by "idle -t 'foo'", this script is more
convenient. In addition, a shell and an editor window can be started
in parallel by "idles -e foo.py".

"Amazing. A very subtle change in policy in descr-branch actually
found a bug here. Here's the deal: Class PyShell derives from class
OutputWindow. Method PyShell.close()
wants to invoke its parent method, but because PyShell long ago was
inherited from class PyShellEditorWindow, it invokes
PyShelEditorWindow.close(self). Now, class PyShellEditorWindow itself
derives from class OutputWindow, and inherits the close() method from
there without overriding it. Under the old rules,
PyShellEditorWindow.close would return an unbound method restricted to
the class that defined the implementation of close(), which was
OutputWindow.close. Under the new rules, the unbound method is
restricted to the class whose method was requested, that is
PyShellEditorWindow, and this was correctly trapped as an error." --GvR
