Changes in 2.2 since 2.1.1
|
|
----------------------------
|
|
|
|
These release notes refer to Mac-specific changes only. See NEWS (in the Misc folder)
|
|
for machine-independent changes.
|
|
|
|
|
|
- The main change is that all toolbox modules have moved to a package called Carbon.
|
|
So things like "import Res" should be changed to "from Carbon import Res", and
|
|
"from Res import *" to "from Carbon.Res import *". Please see the readme file for
|
|
some open questions and join the discussions on pythonmac-sig if you have anything
|
|
to contribute. Aside from reducing clutter this change will also benefit the
|
|
port to Mach-O/OSX Python later.
|
|
- All toolbox modules have been updated to Universal Headers 3.4.
|
|
- Toolbox modules are weaklinked against InterfaceLib (for PPC builds) and raise
|
|
an exception when you call an unimplemented one on an old MacOS.
|
|
- On input MacPython now accepts either \n (unix style) or \r (mac style) newlines
|
|
for text files. This behaviour can be turned off with a preference.
|
|
This is an experimental feature; again: feedback is requested.
|
|
- The IDE looks better on OS X, but still not as good as on OS9.
|
|
- Command-dot handling has been improved a lot: scripts are now much easier to interrupt,
|
|
and they only scan for cmd-. while in the foreground.
|
|
- "Copy" from the MacPython console window was always disabled. Fixed.
|
|
- This release should run on MacOS 8.1 again.
|
|
- A new, rather different GUSI I/O library is used.
|
|
- time.time() returns positive values again.
|
|
- There is a new module macresource which makes it easier to open a resource file
|
|
accompanying your script when the script is not (yet) converted to an applet.
|
|
This module will later also do the right thing in Mach-O/OSX Python.
|
|
- (Carbon only) experimental modules Carbon.CG (CoreGraphics) and CarbonEvt have
|
|
been added.
|
|
- A new, experimental module hfsplus is included, which gives access to some of the
|
|
functionality of the HFS+ API.
|
|
- A new, experimental module gives access to Carbon Events.
|
|
- Threads had a stack that was too small for many serious Python applications (20K).
|
|
They now get 64K. There is still no overflow check, though.
|
|
- Garbage collection and the gc module have (finally) been enabled.
|
|
- EasyDialogs.ProgressBar now has indeterminate progressbars if you specify maxval=0.
|
|
This is also the new default. Patch supplied by Dean Draayer.
|
|
- There are new preferences for enabling old-style division warnings and for
|
|
accepting unix-style newlines in text input files. These can also be set during
|
|
startup, and in addition you can select very verbose import tracing.
|
|
- The NavServices override for StandardFile has moved from early startup to the
|
|
time you import macfs. This speeds up MacPython startup.
|
|
- Various outdated scripts have been moved to :Mac:Unsupported.
|
|
- Various outdated items from :Mac:Lib:test have been removed.
|
|
- C Developers: you know have control over the Python console if you are embedding
|
|
MacPython in another application, thanks to Alexandre Parenteau. :Mac:Demo:embed.html
|
|
has very minimal documentation.
|
|
- BuildCGIApplet works again.
|
|
- The CodeWarrior OSA suite missed quit(). It is back.
|
|
- Contrib:morefindertools is gone, the functionality has been integrated into
|
|
the standard module findertools.py.
|
|

|
Known problems
|
|
--------------
|
|
|
|
This list is probably incomplete, more problems may be listed on the MacPython homepage,
|
|
http://www.cwi.nl/~jack/macpython.html.
|
|
|
|
- MacPython 2.2 (and MacPython 2.1) will not run correctly on a multiprocessor MacOS X
|
|
machine, it will quickly deadlock during I/O operations. The GUSI I/O library is suspected,
|
|
hints/clues/workarounds are solicited. This problem also occurs intermittently on fast
|
|
OS X single-processor machines.
|
|
- 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).
|
|
- The IDE object and class browser look funny on OSX, but they work fine.
|
|
- Aliases may not work in sys.path entries.
|
|
- 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.
|
|
- AliasMenu 2.2 conflicts with the Carbon version of Python. This is most likely a problem
|
|
with AliasMenu (which is from 1999, and thus predates Carbon altogether).
