[Pharo-project] [BUG]UndefinedObject(Object)>>doesNotUnderstand: #update

by Ben Coman

I was using DrGeo for the first time from the bundled release 11.08 on Windows 7. About 30 minutes in I drew three equally intersecting circles, added a reflection line with each circle reflected. I added a free point with a middle (I think to a circle) and was trying to add a locus. When moving any of the points defining the circles I am getting a dozen or more cascading MNUs down the screen. Moving the reflection line still works okay. The error occurs in following method... DrGeo>>updateDirtyCostumes self presenter tool costumes do: [ :each | each update ]. self area changed In the debugger inspecting "self presenter tool costumes" returns nil. While I can't judge whether returning nil is valid here, as a Smalltalk newbie what I am really interested in is: 1. The semantics of sending a "do:" message to nil. By the principle of least surprise I would expect that it would do ...nothing, whereas here it tries later sending the "update" method to it. 2. Why in lines 0027 and 0641 is the "do:" method received by OrderedCollection and not UndefinedObject? Actually I can't see "do:" in the hierarchy of UndefinedObject, so why does UndefinedObject not raise a MNU for "do:" ? The image with the error is available at... http://blog.openinworld.com/miscfiles/DrGeo-updateDirtyCostumes-MNU-2011-10… The stack trace generated by the <Mail out bug report> menu item is below. I wasn't sure how much of it to cut or leave, so I've left it all. ------------------8<------------------------- 00000001 22 October 2011 10:27:03 pm 00000002 00000003 VM: Win32 - IX86 - NT -

NullStream new is unprintable which seems to trigger the emergency evaluator when entering the debugger. Since the inspector can live with unprintable objects, so should the debugger. Has this already been turned into an issue ? If not, I will do it. Sven

That's helpful to illustrate the problem. Of course, the concern is not that the code is wrong (no argument there), it's the fact that 1.3 goes nuts rather than simply displaying a walkback. 1.4 exhibits the same defect. My 1.1.1 image "gets it right," (goes directly to the walkback), but that is using a non-Cog vm. ________________________________________ From: pharo-project-bounces(a)lists.gforge.inria.fr [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of mmimica [milan.mimica(a)gmail.com] Sent: Saturday, October 22, 2011 5:33 AM To: pharo-project(a)lists.gforge.inria.fr Subject: Re: [Pharo-project] [ANN 1.3] One-Click #13315 Schwab,Wilhelm K wrote: > > I still get the error handling failure when attempting > > HtmlParser parse:Clipboard default clipboardText readStream. > > Again, the expression is wrong, but it should give only a walkback, not > the preceding error. > Oh I can reproduce this one easily: Just do this: | buf out | buf := ByteArray new: 1024. out := NullStream new.
