Enhanced & Extended Serial Port support.
by John M McIntosh 11 May '04

11 May '04

I've push a changeset and macintosh plugins onto the server, they should appear in a few days. The SerialExtendedMacOS9Plugin.sit goes in the mac 3.5 noncarbon plugin location The SerialExtendedUnixPlugin.bundle goes in the mac 3.5 carbon plugin location {yes the name implies unix, but os-x is unix...} The EnhancedSerialPorts-JMM changeset which is the classes and plugin interface logic you need to file in. I suspect usage will be limited but it enables you to do things with serial ports (and file handles, hint any file handle) that you can't do otherwise. I would think to compile this code on your favorite Linux box that would be a snap. Only one platform specific primitive or method exists serialPortFindNamesPlusKeysstorage which on os-x invokes the IOServiceGetMatchingServices() call to get path names to devices that support the serial protocols. This primitive call a common Linux box could be replaced by smalltalk code to iterate over /dev or read some sort of control file etc to figure out the path names to the serial devices. For mac os-9 this functionality was already part of the VM. I'm hoping that no platform specific C code will be required for unix boxes. Alas windows users require someone to do the dirty work if you want windows specific serial calls? Or will unix emulation somewhere/how etc work? Couldn't speak for parallel ports, never even occurred to me to investigate till now. I should point out that Dan Ingalls <Dan(a)SqueakLand.org> was kind enough to actually fund with real USA $ some of the work required to build this plugin, then willing to release it to the public. So enjoy, and thank Dan for motivating ($) me to write the code and for releasing it. PS I won't pass up an opportunity to point out if you've an obscure macintosh specific feature you would like and like Dan have a bit of cash to pay for it, then we should talk. -- ======================================================================== === John M.

[BUG][3.6] Resignalling an exception
by Avi Bryant 11 May '04

11 May '04

Try the following line of code in both 3.5 and 3.6: [1/0] on: Error do: [:e | e signal] In 3.5, when the debugger comes up, the top context is the send to #/. In 3.6, it is the handler block, with the send to #/ several frames down. Which is correct? I personally much prefer the 3.5 behavior. Another symptom of what I think is the same bug: [1/0. self inform: 'inner'] on: Error do: [:e | e defaultAction. self inform: 'outer']. Try this code. When the notifier pops up, click Proceed. In 3.5, you will see 'inner'. In 3.6, you will see 'outer'. Again, I would prefer the 3.5 behavior here. Does anyone know what exactly has changed, and how easy it is to fix?

"FileDirectory default directoryExists: FileDirectory default pathName" ^(self directoryNamed: filenameOrPath ) exists ++++++++++++++ Cheers, Bob

[FIX][KCP][3.6a] IfUnhandledError-nk
by ned＠bike-nomad.com 29 Apr '04

29 Apr '04

from preamble: "Change Set: IfUnhandledError-nk Date: 27 June 2003 Author: Ned Konz This changeset: - edits all callers of BlockContext>>ifError: to use something else, usually #ifUnhandledError: - adds BlockContext>>ifUnhandledError: (see below) - marks BlockContext>>ifError: as deprecated - edits all callers of Semaphore>>critical:ifError: to use something else. - marks Semaphore>>critical:ifError: as deprecated - edits most callers of on: Error do: [ ... ] to use something else, mostly #ifUnhandledError: - restores the behavior of removing step messages from the WorldState step list when the step messages have an error (the 'start stepping again' debug menu choice will restart them) I wrote #ifUnhandledError:, which allows enclosing scopes to handle exceptions. This behaves exactly the same as #ifError:, except that: - if there is an outer exception handler, that handler gets to handle the exception instead, and - there is now a one-argument form as well as the 0 and 2 argument forms that gets passed the exception itself.

[FIX] AddAllFix-ac
by andrew＠beta4.com 07 Apr '04

07 Apr '04

from preamble: "Change Set: AddAllFix-ac Date: 6 August 2003 Author: Andrew Catton Fixed bug where: someCollection addAll: someCollection causes an infinite loop. - #addAll*: methods now use a copy of the parameter if it is the same as the receiver. - The old behavior was moved to #basicAddAll*: variants. - #basicAddAll: is used by SortedCollection>>copy to avoid an #addAll:->#copy->#addAll: infinite loop when adding a collection to itself. - Removed OrderedCollection>>addAll: as it didn't actually change the semantics inherited from Collection>>addAll: and would have required a further override on SortedCollection had it remained."!

[BUG] Hidden Information/HyperText, alt-6 in GeeMail
by David Faught 26 Mar '04

26 Mar '04

In the TextPlus area of a GeeMail morph, the alt-6 menu comes up, but does not work properly. Specifically, entering: A Link<http://www.whatever.com> selecting all that text, doing alt-6 (on Windows), and selecting "be a Web URL Link" from the menu gives the following result: A Link<http://www.whatever.com>[No hidden info] and no link is inserted. This is in a 3.5 image. __________________________________ Do you Yahoo!? Yahoo! SiteBuilder - Free, easy-to-use web site design software http://sitebuilder.yahoo.com

[BUG] FileContentsBrowser doesn't filein 'all' protocol
by Tim Rowledge 10 Mar '04

10 Mar '04

Just noticed this; in a filecontents browser if you pick a class youcan filein all the stuff for that class. If you pick a protocol you can filein all the methods in that protocol. However, if you pick 'all' protocol, you don't get to filein all the methods visible.

[ENH] addHorzScrollbar
by sps2000＠mail.com 29 Feb '04

29 Feb '04

from preamble: "Change Set: scrollport Date: 28 December 2002 Author: Steven Swerling I was adding a horizontal scrollbar to the SimpleHierarchicalListMorph, but realized that many of the methods would be generic to any subclass of ScrollPane. And there were many methods. So I moved the changes up to ScrollPane. This changeset adds a horizontal scrollbar to ScrollPane, which appears as needed. I don't know if there is any demand for this, so I'm just running it up the flagpole. WARNING: The last thing you need is for a bug in ScrollPane. I don't know of any in this code, but better safe then sorry. So consider this a beta. Please tinker around with your applications to make sure everything is working ok before saving your image. Tested on a fresh 3.4 image w/ updates up to #5138. "!
