Changes in 2.1 since 2.0
|
|
--------------------------
|
|
|
|
These release notes refer to Mac-specific changes only. See NEWS (in the Misc folder)
|
|
for machine-independent changes. Changes since 2.1b2 are
|
|
marked with [*] and at the bottom of the list.
|
|
|
|
- This release is optionally Carbon-based, so it runs natively on MacOS 8.1 or
|
|
later and MacOSX. (Note that on MacOSX MacPython will run as a normal Mac application,
|
|
if you want to run Python from the BSD commandline get a unix-Python distribution
|
|
from www.python.org).
|
|
- Alternatively there is a classic PPC interpreter as well. There are two reasons you
|
|
might want to use this: (a) you have a pre-MacOS9 system and don't want to install
|
|
CarbonLib, or (b) you need Tkinter, for which no Carbon version is available yet.
|
|
- Distutils is included and seems to work. On 8.1 you may want to get Apple's
|
|
CarbonLib installer even if you plan to run classic, it contains the newer Appearance
|
|
Mgr which Python needs (according to rumour).
|
|
- There's a new module (package, actually) mkcwproject which builds CodeWarrior
|
|
projects from simple templates. See Distutils or :Mac:scripts:genpluginprojects.py
|
|
for examples of use.
|
|
- The Numerical extension has moved to :Lib:site-python from :Extensions. As Numerical
|
|
is now distutils-based you can easily install newer versions when they become
|
|
available.
|
|
- The Help and ctb modules are not available under Carbon because that functionality is
|
|
not in Carbon.
|
|
- Windows and Dialogs can now be different beasts, so you may have to call
|
|
dlg.GetDialogWindow() where you used to be able to call window methods straight
|
|
on the dialog. This also has consequences for code using FrameWork.DialogWindow.
|
|
THIS IS AN INCOMPATIBLE CHANGE.
|
|
- ctl.GetControlDataHandle() has been renamed to GetControlData_Handle(), and similarly
|
|
for the other variants of GetControlData and SetControlData. This was needed
|
|
because Carbon defines a completely different routine with the name GetControlDataHandle.
|
|
THIS IS AN INCOMPATIBLE CHANGE.
|
|
- Method mac.xstat() has disappeared. THIS IS AN INCOMPATIBLE CHANGE.
|
|
- Menu.SetPopupData() and GetPopupData() are gone. Use SetPopupMenuHandle() and
|
|
SetPopupMenuID() (and the getters) in stead. THIS IS AN INCOMPATIBLE CHANGE.
|
|
- Various methods have disappeared when running under Carbon. The script
|
|
:Mac:scripts:missingcarbonmethods.py can check your sources, but you need unix to run
|
|
it. Or use it as documentation and search by hand. THIS IS AN INCOMPATIBLE CHANGE.
|
|
- The good news is that "direct access to toolbox structs" still works from Python,
|
|
so Python programmers have a lot less to fix than C programmers.
|
|
That's because the lowlevel code simply uses the accessors internally. The accessors
|
|
are available both in Carbon and Classic MacPython.
|
|
- Scrap under Carbon is, you guessed it, the Carbon Scrap Manager. Some workarounds are
|
|
provided, though. THIS IS AN INCOMPATIBLE CHANGE.
|
|
- The Internet Config routines that are missing from Carbon have been removed. This
|
|
is no problem if you use the "ic" module, but may be if you use "icglue" directly.
|
|
THIS IS AN INCOMPATIBLE CHANGE.
|
|
- Various old toolbox names (CountMItems, EnableItem, etc) have disappeared. Use the
|
|
new forms (CountMenuItems, EnableMenuItem, etc). THIS IS AN INCOMPATIBLE CHANGE.
|
|
- Waste now uses Waste 2.0.
|
|
- The default memory size for the interpreter has been upped again.
|
|
- The MacOS error messages have been updated to reflect the current state of
|
|
things. This was long overdue.
|
|
- The crash in BuildApplication has been fixed.
|
|
- struct.pack related problems (in Audio_Mac, for example) have been fixed.
|
|
- (src/dev/cvs only): The project files now use the .mcp extension in stead of .prj.
|
|
Projects for almost all plugins and the img modules are automatically generated
|
|
with :Mac:scripts:genpluginprojects.py (also called by fullbuild). The .mcp files
|
|
are not in the repository, if you don't want to use genpluginprojects you can import
|
|
the .mcp.xml files in CodeWarrior.
|
|
- ConfigurePython has been replace by two applets: ConfigurePythonClassic and
|
|
ConfigurePythonCarbon. These will select either execution model for machines
|
|
supporting both, and it will also build all the standard applets.
|
|
- PythonInterpreterCarbon and PythonInterpreterClassic are now files of type "Atmp", not
|
|
"APPL", so there should not be any confusion as to what the real application is
|
|
(PythonInterpreter).
|
|
- A BBEdit language module by Chris Stern is included in the :Mac:Contrib folder.
|
|
- The ConfigurePython applets will now detect if the preference file refers to a different
|
|
folder than where they live. They offer to remove the preference file in this case.
|
|
- Import case-check was broken in 2.1b1, this is fixed.
|
|
- A side-effect of the previous fix is that getpass works again.
|
|
- BuildApplication was broken under Carbon. Fixed.
|
|
- Morefindertools functionality integrated into findertools. [*]
|
|
- ped.py from Mac:Demo crashed, this has been fixed by making Win.WhichWindow more robust. [*]
|
|
- Tkinter mainloop is now a little less aggressive in eating events. [*]
|
|
- The Python console window is raised to the front when input is read. This fixes a hang
|
|
(for Carbon only) when crashing with a modal dialog open. [*]
|
|
- The menu bar is (again) restored when Python is terminating. [*]
|
|
|
|
|
|
What is not in this distribution
|
|
--------------------------------
|
|
|
|
- The garbage collection mods have not been enabled, mainly due to lack of test-time.
|
|
- Stackless Python/microthreads hasn't been ported to 2.1 yet. If/when it becomes available
|
|
Just will undoubtedly announce it on pythonmac-sig and the MacPython homepage.
|
|
|
|
Known problems
|
|
--------------
|
|
|
|
This list is probably incomplete, more problems may be listed on the MacPython homepage,
|
|
http://www.cwi.nl/~jack/macpython.html.
|
|
|
|
- Tkinter does not work under Carbon.
|
|
- The IDE and Tkinter do not work together. Run tkinter programs under PythonInterpreter.
|
|
- Tkinter file events do not work, unless you have opened the file through Tcl (but then
|
|
you cannot access it from Python).
|
|
- Aliases may not work in sys.path entries.
|
|
- Under Carbon on OS9 only you may occasionally see a spurious KeyboardInterrupt. I have absolutely
|
|
no clue as to what is causing this.
|
|
- PythonInterpreter used interactively will eat a lot of processor cycles. You should use
|
|
PythonIDE for interactive work and PythonInterpreter for scripts only. This is especially
|
|
true under OSX.
