Hi! today I started to look at of why my benchmark in the CI stalled/didn't complete and I see three separate issues and wonder how to address them properly? I have a truncated log attached Issues: * In my CI script I disable Deprecation warnings but this has no influence on Deprecation>>#transform. This means that it will try to write the changes?! To scale we start the same image multiple times. * Somehow writing the log fails (and the TCP connection fails the same time?!) with a primitive error. * Errors "recurse". So while we try to exit the image it seems to fail the same way and tries again.. which fails again.. which fails again..at some point no new context will be allocated. Solutions? * Prevent new errors in NonInteractiveUIManager>>#unhandledErrorDefaultAction:? * Check in >>#transform if transformation is disabled and then return early? * ??? No idea.. I will strace to see what happens to the Debug log.. but ideally I would like this file writing to be disabled. :) Should I create tickets? holger dispatch failed on "[ self doExpire. statsdClient flush ]". an OrderedCollection(MultiByteFileStream(Object)>>primitiveFailed: MultiByteFileStream(Object)>>primitiveFailed MultiByteFileStream(StandardFileStream)>>primFlush: MultiByteFileStream(StandardFileStream)>>flush MultiByteFileStream(WriteStream)>>nextChunkPut: SourceFileArray>>writeSource:preamble:onSuccess:onFail: CompiledMethod>>putSource:withPreamble: CompiledMethod>>putSource:class:category:withStamp:priorMethod: VODescriptionBuilder class(ClassDescription)>>logMethodSource:forMethod:inCategory:withStamp: VODescriptionBuilder class(ClassDescription)>>compile:classified:withStamp:notifying:logSource: VODescriptionBuilder class(ClassDescription)>>compile:classified:withStamp:notifying: VODescriptionBuilder class(ClassDescription)>>compile:classified:notifying: VODescriptionBuilder class(ClassDescription)>>compile:classified: [ aMethod origin compile: aMethod ast formattedCode classified: aMethod protocol ] in Deprecation>>transform BlockClosure>>ensure: Author>>useAuthor:during: Author class>>useAuthor:during: Deprecation>>transform Pragma(Object)>>deprecated:transformWith: Pragma>>selector) <snip log about lost TCP connection> PrimitiveFailed: primitive #primClose: in MultiByteFileStream failed MultiByteFileStream(Object)>>primitiveFailed: MultiByteFileStream(Object)>>primitiveFailed MultiByteFileStream(StandardFileStream)>>primClose: MultiByteFileStream(StandardFileStream)>>close SmalltalkImage>>closeLog: [ self closeLog: logStream ] in SmalltalkImage>>logDuring: in Block: [ self closeLog: logStream ] BlockClosure>>ensure: SmalltalkImage>>logDuring: NonInteractiveUIManager(CommandLineUIManager)>>inform: STCommandLineHandler(Object)>>inform: STCommandLineHandler>>handleError:reference: [ :e | self handleError: e reference: aReference ] in STCommandLineHandler>>handleErrorsDuring:reference: in Block: [ :e | self handleError: e reference: aReference ]...etc...
