[#521782] unreliable file.read() error handling
* Objects/fileobject.c
(file_read): Clear errors before leaving the loop in all situations,
and also check if some data was read before exiting the loop with an
EWOULDBLOCK exception.
* Doc/lib/libstdtypes.tex
* Objects/fileobject.c
Document that sometimes a read() operation can return less data than
what the user asked, if running in non-blocking mode.
* Misc/NEWS
Document the fix.
[#448679] Left to right
* Python/compile.c
(com_dictmaker): Reordered evaluation of dictionaries to follow strict
LTR evaluation.
* Lib/compiler/pycodegen.py
(CodeGenerator.visitDict): Reordered evaluation of dictionaries to
follow strict LTR evaluation.
* Doc/ref/ref5.tex
Documented the general LTR evaluation order idea.
* Misc/NEWS
Documented change in evaluation order of dictionaries.
[#636769] Fix for major rexec bugs
* Lib/rexec.py
(FileBase): Added 'xreadlines' and '__iter__' to allowed file methods.
(FileWrapper.__init__): Removed unnecessary self.f variable, which gave
direct access to the file object.
(RExec): Added 'xreadlines' and '_weakref' to allowed modules.
(RExec.r_open): Convert string subclasses to a real string classes
before doing comparisons with mode parameter.
* Lib/ihooks.py
(BasicModuleImporter.import_module/reload/unload): Convert the module
name to a real string before working with it.
(ModuleImporter.import_module/import_it/reload): Convert the module
name to a real strings before working with it.
* Misc/NEWS
Document the change.

Idlefork SF Bug 440383 - IDLE goes into beep loop
Fix loop in EditorWindow.newline_and_indent_event() and
in addition fix submission of >>> prompt to PyParse.Parser
Eliminate extra attribute EditorWindow.auto_indent
way to get various alias creation routines as methods of FSSpec or FSRef
objects (which is the logical thing, from a Python POV). Also started on
the code that will contain all the macfs functionality, so macfs can
becode a Python module, to be used mainly for backward compatibility.
M IOBinding.py
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
PyMapping_Check() doesn't guarantee that PyMapping_Size() won't raise
an exception, nor that keys and values are lists.
Also folded some long lines and did a little whitespace normalization.
Probably a 2.2 backport candidate.
