I will add that behavior but not with that name.. It does not say anything to me I think it would work out of the box with just one variable... origin would denote the logical place the method has been defined: normal method: the class trait method: the trait class extension method: the package I think that would make things quite clear...

origin is not the same as package in CompiledMethod origin refers to the class or trait that actually defines the method we do not have that in Ring. I will add that behavior but not with that name..

Hi Sean. I am still seing the problem :( It is difficult to make it YOU to reproduce it, but it is easy that tomorrow I show it to you :) Basically, what is happening is that ZnClient >> executeRequestResponse self logRequest. ZnSignalProgress enabled ifTrue: [ HTTPProgress signal: 'Writing request' ]. request writeOn: connection. connection flush. ZnSignalProgress enabled ifTrue: [ HTTPProgress signal: 'Reading response' ]. response := request method = #HEAD ifTrue: [ ZnResponse readHeaderFrom: connection ] ifFalse: [ self streaming ifTrue: [ ZnResponse readStreamingFrom: connection ] ifFalse: [ ZnResponse readFrom: connection ] ]. self logResponse throws a mustBeBoolean in the first line "ZnSignalProgress enabled ". It seems that such expression answered the SmallINteger 30 the first time. If I take the debugger and I evaluate ZnSignalProgress enabled again, it answers me false, which is the correct value. Ahh yes, this in latest 2.0. Thanks! On Fri, Aug 17, 2012 at 10:32 PM, Mariano Martinez Peck < marianopeck(a)gmail.com> wrote: > Hi Frank and Sean. The problem was quite hard to reproduce.

Re: [Pharo-project] 'self halt' safety net

you can open .changes file in another image to rescue your code. also you can patch the image's bytecode to avoid entering an offending method (like a method which enters the drawing , just see its bytecode in another image, and the find same byte sequence in crashing image, and put return self bytecode) On 25 August 2012 03:42, Ben Coman <btc(a)openinworld.com> wrote: > Igor Stasenko wrote: >> >> On 4 August 2012 04:11, Ben Coman <btc(a)openinworld.com> wrote: >> >>> >>> As probably many newbies do from time to time, I am learning the system >>> splattering 'self halt' around, and once again slipped one into the wrong >>> place where I should have used 'haltOnce' and had a massive number of >>> pre-debugger windows come up.

This is not 'halt' related but just a typo... (which suddenly makes the whole system feel a bit fragile) Working on a small new feature in the drawing loop of Roassal, I would guess "all" that I did was leave out a full stop at the end a line. So the image locked and crashed after about 20 seconds. Unfortunately now the image is crashing every time I try to open it. Some mechanism to throttle and temporarily ignore the error to allow me to rectify the problem would have been immensely useful. In this case, perhaps something like blocking the main UI loop and presenting a modal window of a very basic self contained text editor on the offending method. At this moment, another immensely useful tool would be able to diff the source code between a running image and an offline image, and import the changes. Is there any other way I might recover recent changes? Previously I have not had much luck mixing a new image with the changes file fromt he crashed image. regards -ben ---------------------------------------- THERE_BE_DRAGONS_HERE MessageNotUnderstood: SmallInteger>>Transcript 25 August 2012 8:58:18.345 am VM: Win32 - IX86 - 6.1 - CoInterpreter VMMaker-oscog-EstebanLorenzano.158 uuid: 82eded98-68af-4c80-a472-4f6de293adcf May 1 2012, StackToRegisterMappingCogit VMMaker-oscog-EstebanLorenzano.158 uuid: 82eded98-68af-4c80-a472-4f6de293adcf May 1 2012, https://git.gitorious.org/cogvm/blessed.git Commit: 6aa3fd0f1188078d3167dec1a53031a61b97b688 Date: Tue May 1 20:28:14 2012 +0200 By: Esteban Lorenzano <estebanlm(a)gmail.com> Image: Pharo1.4 [Latest update: #14457] SmallInteger(Object)>>doesNotUnderstand: #Transcript Receiver: 1 Arguments and temporary variables: aMessage: Transcript exception: MessageNotUnderstood: SmallInteger>>Transcript resumeValue: nil Receiver's instance variables: 1 ROOrthoVerticalLineShape>>lineSegmentsFor: Receiver: a ROOrthoVerticalLineShape Arguments and temporary variables: --------------------------------------------------------------------- Sat Aug 25 09:15:38 2012 Error in the VM thread Reason: out of memory Hardware information: Manufacturer: Unknown Model: Unknown Number of processors: 4 Page size: 4096 Memory Information (upon launch): Physical Memory Size: 4194303 kbytes Physical Memory Free: 4194303 kbytes Page File Size: 4194303 kbytes Page File Free: 4194303 kbytes Virtual Memory Size: 2097024 kbytes Virtual Memory Free: 2030848 kbytes Memory Load: 21 percent Processor 0: AMD A10-4600M APU with Radeon(tm) HD Graphics Identifier: AMD64 Family 21 Model 16 Stepping 1 ~MHZ: 2295 Processor 1: AMD A10-4600M APU with Radeon(tm) HD Graphics Identifier: AMD64 Family 21 Model 16 Stepping 1 ~MHZ: 2295 Processor 2: AMD A10-4600M APU with Radeon(tm) HD Graphics Identifier: AMD64 Family 21 Model 16 Stepping 1 ~MHZ: 2295 Processor 3: AMD A10-4600M APU with Radeon(tm) HD Graphics Identifier: AMD64 Family 21 Model 16 Stepping 1 ~MHZ: 2295 Operating System: Windows 7 Home Premium (Build 7601 Service Pack 1) Registered Owner: Ben Registered Company: Toshiba SP major version: 1 SP minor version: 0 Suite mask: 300 Product type: 1 Display Information: Graphics adapter name: AMD Radeon HD 7660G Primary monitor resolution: 1366 x 768 Device: RDPDD Chained DD Adapter String: ???
