Jack Jansen | 26d7c14 | 2000-09-11 22:47:12 +0000 | [diff] [blame] | 4 | These release notes refer to Mac-specific changes only. See NEWS (in the Misc folder) |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 5 | for machine-independent changes. Changes that are new in 2.2b2 are flagged as such. |

Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 8 | - The main change is that all toolbox modules have moved to a package called Carbon. |
| 9 | So things like "import Res" should be changed to "from Carbon import Res", and |
| 10 | "from Res import *" to "from Carbon.Res import *". Please see the readme file for |
| 11 | some open questions and join the discussions on pythonmac-sig if you have anything |
| 12 | to contribute. Aside from reducing clutter this change will also benefit the |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 13 | port to Mach-O/OSX Python later. |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 14 | - On input MacPython now accepts either \n (unix style) or \r (mac style) newlines |
Jack Jansen | f7e5714 | 2001-09-08 21:38:26 +0000 | [diff] [blame] | 15 | for text files. This behaviour can be turned off with a preference. |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 16 | This is an experimental feature; again: feedback is requested. |
| 17 | - Command-dot handling has been improved a lot: scripts are now much easier to interrupt, |
| 18 | and they only scan for cmd-. while in the foreground. [2.2b2] |
| 19 | - "Copy" from the MacPython console window was always disabled. Fixed. [2.2b2] |
| 20 | - This release should run on MacOS 8.1 again. [2.2b2 build 116] |
| 21 | - A new, rather different GUSI I/O library is used. Please report any strange behaviour |
| 22 | with I/O to the pythonmac-sig mailing list! [2.2b2] |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 23 | - There is a new module macresource which makes it easier to open a resource file |
| 24 | accompanying your script when the script is not (yet) converted to an applet. |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 25 | This module will later also do the right thing in Mach-O/OSX Python. |
| 26 | - A new, experimental module hfsplus is included, which gives access to some of the |
| 27 | functionality of the HFS+ API. [2.2b2] |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 28 | - Threads had a stack that was too small for many serious Python applications (20K). |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 29 | They now get 64K. There is still no overflow check, though. |
| 30 | - Garbage collection and the gc module have (finally) been enabled. |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 31 | - EasyDialogs.ProgressBar now has indeterminate progressbars if you specify maxval=0. |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 32 | This is also the new default. Patch supplied by Dean Draayer. |
Jack Jansen | f7e5714 | 2001-09-08 21:38:26 +0000 | [diff] [blame] | 33 | - There are new preferences for enabling old-style division warnings and for |
| 34 | accepting unix-style newlines in text input files. These can also be set during |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 35 | startup, and in addition you can select very verbose import tracing. |
| 36 | - The NavServices override for StandardFile has moved from early startup to the |
| 37 | time you import macfs. This speeds up MacPython startup. |
| 38 | - Various outdated scripts have been moved to :Mac:Unsupported. |
| 39 | - Various outdated items from :Mac:Lib:test have been removed. |
Jack Jansen | 5d528b7 | 2001-10-23 22:22:09 +0000 | [diff] [blame] | 40 | - C Developers: you know have control over the Python console if you are embedding |
| 41 | MacPython in another application, thanks to Alexandre Parenteau. :Mac:Demo:embed.html |
| 42 | has very minimal documentation. |
| 43 | - BuildCGIApplet works again. |
| 44 | - The CodeWarrior OSA suite missed quit(). It is back. |
| 45 | - Contrib:morefindertools is gone, the functionality has been integrated into |
| 46 | the standard module findertools.py. |

| 49 | -------------------------------- |
| 50 | |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 51 | - Stackless Python/microthreads hasn't been ported to 2.2 yet. If/when it becomes available |
Jack Jansen | de51909 | 2000-10-12 21:21:43 +0000 | [diff] [blame] | 52 | Just will undoubtedly announce it on pythonmac-sig and the MacPython homepage. |
Jack Jansen | 028f2d5 | 2001-08-29 22:04:08 +0000 | [diff] [blame] | 53 | - The toolbox modules have not been updated to Universal Header 3.4 or CarbonLib 1.4 yet. |

| 57 | |
Jack Jansen | c1218bc | 2001-04-25 22:11:24 +0000 | [diff] [blame] | 58 | This list is probably incomplete, more problems may be listed on the MacPython homepage, |

| 60 | |
Jack Jansen | b3be216 | 2001-11-30 14:16:36 +0000 | [diff] [blame] | 61 | - MacPython 2.2b2 (and MacPython 2.1) will not run correctly on a multiprocessor MacOS X |
Jack Jansen | cbed91b | 2001-08-03 13:31:36 +0000 | [diff] [blame] | 62 | machine, it will quickly deadlock during I/O operations. The GUSI I/O library is suspected, |
| 63 | hints/clues/workarounds are solicited. |
Jack Jansen | 9de05f4 | 2001-03-20 23:30:38 +0000 | [diff] [blame] | 64 | - Tkinter does not work under Carbon. |
Jack Jansen | 26d7c14 | 2000-09-11 22:47:12 +0000 | [diff] [blame] | 65 | - The IDE and Tkinter do not work together. Run tkinter programs under PythonInterpreter. |
Jack Jansen | 4c52203 | 2001-03-08 23:07:16 +0000 | [diff] [blame] | 66 | - Tkinter file events do not work, unless you have opened the file through Tcl (but then |
| 67 | you cannot access it from Python). |
Jack Jansen | c1218bc | 2001-04-25 22:11:24 +0000 | [diff] [blame] | 68 | - Aliases may not work in sys.path entries. |
Jack Jansen | 4c52203 | 2001-03-08 23:07:16 +0000 | [diff] [blame] | 69 | - PythonInterpreter used interactively will eat a lot of processor cycles. You should use |
Jack Jansen | c1218bc | 2001-04-25 22:11:24 +0000 | [diff] [blame] | 70 | PythonIDE for interactive work and PythonInterpreter for scripts only. This is especially |
| 71 | true under OSX. |
Jack Jansen | cbed91b | 2001-08-03 13:31:36 +0000 | [diff] [blame] | 72 | - AliasMenu 2.2 conflicts with the Carbon version of Python. This is most likely a problem |
| 73 | with AliasMenu (which is from 1999, and thus predates Carbon altogether). |
