About AnObsoleteSunitNameResolver

Hi all,        
   some day until now everytime I run a test (written by me or not) I got
this error message (in debug )

AnObsoleteSUnitNameResolver class>> classNamed (messageNotUnderstand).

This class (AnObsoleteSunitNameResolver) cannot be found in SystemBrowser...

As last thing before this I done a massive update by SqueakMap...

Anyone has any idea about this or how to debug this error
 (as said I cannot find this class nowhere :( )

thanks in advance.

Save your image and in a backup copy you could do:

SmalltalkImage current fixObsoleteReference

If still have obsoletes , you could try:

| outputStream arreglar|
Transcript open.
    outputStream _ ReferenceStream fileNamed: 'clasesObsoletas.txt'.
arreglar _ (Smalltalk obsoleteClasses).
Transcript show: arreglar size;cr.
  1 to: arreglar size do: [:c | (arreglar at:c )
 allInstancesDo: [ :i | i becomeForward: nil].
outputStream nextPut: (arreglar at:c ) printString.
Transcript show: (arreglar at:c ) printString  ;cr.
(arreglar at:c )  becomeForward: nil.].
outputStream close.
3 timesRepeat: [Smalltalk garbageCollect].

And beg you image don't blow :=)

    Lic> Edgar

is there a method to remove only one Obsolete? (most of them are
etoy related, I'm interested in having sunit working again...)

Also, what's these obsolete stuff?

thanks

how can I do that? If search for AnObsoleteSunitNameResolver I don't
find anything...

Using "SystemNavigation default obsoleteClasses" or "Smalltalk
obsoleteClasses" you will see the list of obsoleteClasses. Then you
can continue with the hunt.

(SystemNavigation default obsoleteClasses detect: [:c | c name =
#AnObsoleteSunitNameResolver]) allInstances inspect

or then

(Utilities pointersTo: (SystemNavigation default obsoleteClasses
detect: [:c | c name = #AnObsoleteSunitNameResolver])) inspect

or (in <= 3.8)

(Smalltalk pointersTo: (Smalltalk obsoleteClasses detect: [:c | c name
= #AnObsoleteSunitNameResolver])) inspect

In the inspectors you can find next references using "object pointing
to this value"

using this I got an Array inspector with seven elements

    Pavel> In the inspectors you can find next references using
    Pavel> "object pointing to this value"

doing this I got new inspectors... but I cannot understand how culd I
remove (or rebuild or... I don't know) this reference and subtisute them
with newer.

I suppose there are old references (to object which doesn't exists anymore
in the system) which must be substituted with newer. How could I do that?

thanks very much for your support.

See what in your directory , the "bad cure" should produce a .txt file named
clasesObsoletas.txt.
So , here you could do a forensic analysis of if any obsolete go caught

The complete is  replace ' AnObsoleteUrl' by what was the last in your image
(the last saved to clasesObsoletas.txt)

| outputStream arreglar|
Transcript open.
    outputStream _ ReferenceStream fileNamed: 'clasesObsoletas.txt'.
arreglar _ (Smalltalk obsoleteClasses).
Transcript show: arreglar size;cr.
  1 to: arreglar size do: [:c | (arreglar at:c )
 allInstancesDo: [ :i | i becomeForward: nil].
>>>(arreglar at:c ) printString = 'AnObsoleteUrl' ifTrue: [self halt].
outputStream nextPut: (arreglar at:c ) printString.
Transcript show: (arreglar at:c ) printString  ;cr.
(arreglar at:c )  becomeForward: nil.].
outputStream close.
3 timesRepeat: [Smalltalk garbageCollect].

Instead of "nil" , you could put String new, but the image could blow also.
Sometimes if you change to arreglar _ (Smalltalk obsoleteClasses) reverse,
all obsolete goes.
Or you could need put a self halt and do class by class
It's black art, and we have different spells.
I do many times and if the procedure completes, never have problem again.

> Also, what's these obsolete stuff?
Sounds like someone delete class badly,

I don't know what Squeak are using you
> SmalltalkImage current fixObsoleteReference
>

So if you save in this point, you have a cleaner system .

I afraid what the Pavel tip is more tedious but safer.
Could send mail whit what Smalltalk obsoleteClasses prints ?

Good luck

Edgar

done :) all references are substituted with new ones :))
