Re: [Pharo-project] invalid utf8 input detected

May 17, 2009

      Hi,

I ran the snippet you sent on both 304cl and 306cl and I get the  
following list:

Object->#doesNotUnderstand:
SystemNavigation->#browseMethodsWhoseNamesContain:
Utilities class->#changeStampPerSe
Utilities class->#methodsWithInitials:

Indeed, most of the annoyances are due to the  
Object>>doesNotUnderstand: because when I get a DNU I am stuck (and I  
feel like in Java :)).

I am not sure I understand if there is a fix to the problem.

Cheers,
Doru

There's something weird... If you hit var (UndefinedObject)
doesNotUnderstand: #value: that means there were a problem the first
time.
Unfortunately, due to bug in MethodContext tempNames, we don't know
the class and selector guilty.
From the set of selectors I can see this is Object.
From the source file position, I cannot say anything because I do not
have same change log history (sorry, own image).
You could try
(SourceFiles at: 2) readOnlyCopy position: 10007336; nextChunk

sorry for not checking either.
When I run this code I indeed do not have a problem on 10306cl

when I run your script on the license looking for image
I got using 10306cl
I get the following error:

One solution would be to use getSource rather than
getSourceFromFile.
However, with following code I detected no problem in my pharo- 
core
copy (10281 updated to 10306)

problems := OrderedCollection new.
total := 0.
SystemNavigation default allBehaviorsDo: [:cl | total := total +

Hi,
Recently I encounter a strange error:
- I sometimes get a debugger due to some problems in my code
- when I try to investigate the trace, I get another debugger
saying
that "Invalid utf8 input detected'"
This second debugger I can investigate, the previous not. It  
looks
like something got messed up with the text conversion of the
sources.
I am working on 10306 using the 4.1.1b2 VM on Mac. The code I am
working on is loaded from squeaksource (Moose, Glamour,  
Mondrian).
Anyone can confirm this problem?
Cheers,
Doru
