I have a 4 day old image that just froze. After restarting, I tried to recover the code changes since I saved my image yesterday, but the list of changes in the tool are an unordered list going back to February of this year. Even old code of mine from that time was in the list. After about an hour I managed to manually select the changes I've made since yesterday, and file them out. When I try to file them back in, I get an error from the debugger, and cannot continue. Anyone know what I can do to recover my source, or point me in the right direction to recover from this. This is the stacktrace from the debugger :- From: jt@parspro.com To: Pharo-project@lists.gforge.inria.fr Subject: [BUG]UndefinedObject(Object)>>doesNotUnderstand: #self here insert explanation of what you were doing, suspect changes you've made and so forth. 23 October 2009 4:19:05 pm VM: Mac OS - intel - 1058 - Squeak3.8.1 of '28 Aug 2006' [latest update: #6747] Squeak VM 4.1.1b2 Image: Pharo1.0beta [Latest update: #10477] SecurityManager state: Restricted: false FileAccess: true SocketAccess: true Working Dir /Users/jpt/Dev/repos/Dev-Images/PharoCore-1.0-10477-BETA Trusted Dir /foobar/tooBar/forSqueak/bogus Untrusted Dir /Users/jpt/Library/Preferences/Squeak/Internet/My Squeak UndefinedObject(Object)>>doesNotUnderstand: #self Receiver: nil Arguments and temporary variables: aMessage: self exception: MessageNotUnderstood: receiver of "self" is nil resumeValue: nil Receiver's instance variables: nil UndefinedObject>>DoIt Receiver: nil Arguments and temporary variables: Receiver's instance variables: nil Compiler>>evaluate:in:to:notifying:ifFail:logged: Receiver: a Compiler Arguments and temporary variables: textOrStream: 'publish self status: #Opened ' aContext: nil receiver: nil aRequestor: nil failBlock: [closure] in Compiler class>>evaluate:for:notifying:logged: logFlag: false methodNode: DoIt ^ publish self status: #Opened method: a CompiledMethod(982: UndefinedObject>>DoIt) value: nil toLog: nil itsSelection: nil itsSelectionString: nil Receiver's instance variables: sourceStream: a ReadStream 'publish self status: #Opened ' requestor: nil class: UndefinedObject category: nil context: nil parser: a Parser Compiler class>>evaluate:for:notifying:logged: Receiver: Compiler Arguments and temporary variables: textOrString: 'publish self status: #Opened ' anObject: nil aController: nil logFlag: false Receiver's instance variables: superclass: Object methodDict: a MethodDictionary(#compile:in:classified:notifying:ifFail:->a Comp...etc... format: 142 instanceVariables: #('sourceStream' 'requestor' 'class' 'category' 'context' 'p...etc... organization: ('deprecated' format:in:notifying:contentsSymbol:) ('error handli...etc... subclasses: nil name: #Compiler classPool: a Dictionary() sharedPools: nil environment: Smalltalk category: #'Compiler-Kernel' traitComposition: nil localSelectors: nil Compiler class>>evaluate:for:logged: Receiver: Compiler Arguments and temporary variables: textOrString: 'publish self status: #Opened ' anObject: nil logFlag: false Receiver's instance variables: superclass: Object methodDict: a MethodDictionary(#compile:in:classified:notifying:ifFail:->a Comp...etc... format: 142 instanceVariables: #('sourceStream' 'requestor' 'class' 'category' 'context' 'p...etc... organization: ('deprecated' format:in:notifying:contentsSymbol:) ('error handli...etc... subclasses: nil name: #Compiler classPool: a Dictionary() sharedPools: nil environment: Smalltalk category: #'Compiler-Kernel' traitComposition: nil localSelectors: nil Compiler class>>evaluate: Receiver: Compiler Arguments and temporary variables: textOrString: 'publish self status: #Opened ' Receiver's instance variables: superclass: Object methodDict: a MethodDictionary(#compile:in:classified:notifying:ifFail:->a Comp...etc... format: 142 instanceVariables: #('sourceStream' 'requestor' 'class' 'category' 'context' 'p...etc... organization: ('deprecated' format:in:notifying:contentsSymbol:) ('error handli...etc... subclasses: nil name: #Compiler classPool: a Dictionary() sharedPools: nil environment: Smalltalk category: #'Compiler-Kernel' traitComposition: nil localSelectors: nil [] in ChangeRecord>>fileIn Receiver: a ChangeRecord Arguments and temporary variables: <<error during printing> Receiver's instance variables: file: MultiByteFileStream: '/Users/jpt/Dev/repos/Dev-Images/PharoCore-1.0-10477...etc... position: 29712 type: #doIt class: nil category: nil meta: nil stamp: nil BlockClosure>>ensure: Receiver: [closure] in ChangeRecord>>fileIn Arguments and temporary variables: aBlock: [closure] in CursorWithMask(Cursor)>>showWhile: returnValue: nil b: nil Receiver's instance variables: outerContext: ChangeRecord>>fileIn startpc: 107 numArgs: 0 CursorWithMask(Cursor)>>showWhile: Receiver: ((CursorWithMask extent: 16@16 depth: 1 fromArray: #( 2r0 2r0 2r0 2r10000000010...etc...
