1 Changes in 2.1.1 since 2.1
2 --------------------------
4 These release notes refer to Mac-specific changes only. See NEWS (in the Misc folder)
5 for machine-independent changes.
7 - Handling non-ascii characters in sys.path on non-MacRoman systems should be fixed,
8 iff MacPython has a codec for the charset. Otherwise you should get an error, at least.
9 Pathnames in sys.path also retain their original case again.
10 - IDE could crash on corrupt preferences. Fixed.
11 - IDE will now work if you use either pre or sre as re.
12 - Evt.WaitNextEvent could give an error when bit 15 was set, which could cause a problem
13 with IDE in classic mode. Fixed.
14 - MacOS8.X users in classic mode had problems with Fm not loading, which also caused
15 IDE not working. Fixed.
16 - Fm.IsAntiAliasedTextEnabled and Fm.SetAntiAliasedTextEnabled have gone for now, to
17 fix the problem above.
18 - Disabled the Tkinter file I/O event handler, which was there but didn't work anyway.
19 - Problems with loading dynamic modules that are part of a package into BuildApplication-
20 generated programs were fixed.
21 - The order of the EasyDialogs yes/no/cancel buttons has been conformed to the Mac
22 standard.
23 - Handling of Dialogs and Windows that were not created by Python is a bit more graceful
24 now, which may fix some crashes.
25 - Ctl.SendControlMessage has gone. But it didn't work anyway.
26 - Various problems with the TextEdit and Waste demos have been fixed.
27 - Embedding/extending only: in preparation to allowing the use of MacPython modules in
28 unix-Python on OSX the xxx_New and xxx_Convert routines are now optionally vectored via
29 glue routines in macglue.c. The only change that may be needed for embedders/extenders is
30 that you may want to include pymactoolbox.h in your sources.
31 - Embedding/extending only: Most MacPython source is now much more Mach-O friendly, and
32 should work with Universal Headers 3.4.
33 - Experimental: an Mlte module has been added, an interface to the Multi Lingual Text
34 Engine. There is a minimal example in :Mac:Demos:mlte.
35 - Experimental: some support for FSRef objects has been added. You can do little more that
36 convert them to/from FSSpecs. Carbon only.
37 - Experimental: the CF module has some support for CoreFoundation types. CFString
38 and CFURL work, to a degree, and can be converted to/from Python strings and Unicode
39 objects. Carbon only.
41 What is not in this distribution
42 --------------------------------
44 - The garbage collection mods have not been enabled, mainly due to lack of test-time.
45 - Stackless Python/microthreads hasn't been ported to 2.1 yet. If/when it becomes available
46 Just will undoubtedly announce it on pythonmac-sig and the MacPython homepage.
48 Known problems
49 --------------
51 This list is probably incomplete, more problems may be listed on the MacPython homepage,
52 http://www.cwi.nl/~jack/macpython.html.
54 - MacPython 2.1.1 (and MacPython 2.1) will not run correctly on a multiprocessor MacOS X
55 machine, it will quickly deadlock during I/O operations. The GUSI I/O library is suspected,
56 hints/clues/workarounds are solicited.
57 - Tkinter does not work under Carbon.
58 - The IDE and Tkinter do not work together. Run tkinter programs under PythonInterpreter.
59 - Tkinter file events do not work, unless you have opened the file through Tcl (but then
60 you cannot access it from Python).
61 - Aliases may not work in sys.path entries.
62 - Under Carbon on OS9 only you may occasionally see a spurious KeyboardInterrupt. I have absolutely
63 no clue as to what is causing this.
64 - PythonInterpreter used interactively will eat a lot of processor cycles. You should use
65 PythonIDE for interactive work and PythonInterpreter for scripts only. This is especially
66 true under OSX.
67 - AliasMenu 2.2 conflicts with the Carbon version of Python. This is most likely a problem
68 with AliasMenu (which is from 1999, and thus predates Carbon altogether).
