Uh oh. Why would you think that's a good idea? A configuration can have multiple repositories, so just copying all into into one is not always the right thing to do. At the very least this should warn that it's not just going to store a config, but copy versions over, too. - Bert - > =============== Diff against MonticelloConfigurations-bf.96 =============== > > Item was changed: > ----- Method: MCConfigurationBrowser>>checkDependencies (in category 'dependencies') ----- > checkDependencies > + | missing | > + missing := (self dependencies collect: > + [ : ea | ea versionInfo name ]) asSet. > + self repositories do: > + [ : eachRepository | eachRepository cacheAllFileNamesDuring: > + [ missing copy do: > + [ : eachVersionName | (eachRepository includesVersionNamed: eachVersionName) ifTrue: [ missing remove: eachVersionName ] ] ] ]. > + ^ missing isEmpty or: > + [ self selectDependency: missing anyOne. > + self confirm: > + (String streamContents: > + [ : strm | strm > + nextPutAll: 'No repository found for' ; > + cr. > + missing do: > + [ : r | strm > + nextPutAll: r ; > + cr ]. > + strm nextPutAll: 'Do you still want to store?' ]) ]! > - ^self checkModified and: [self checkMissing]! > > Item was removed: > - ----- Method: MCConfigurationBrowser>>checkMissing (in category 'dependencies') ----- > - checkMissing > - | missing | > - missing := (self dependencies collect: > - [ : ea | ea versionInfo name ]) asSet. > - self repositories do: > - [ : eachRepository | eachRepository cacheAllFileNamesDuring: > - [ missing copy do: > - [ : eachVersionName | (eachRepository includesVersionNamed: eachVersionName) ifTrue: [ missing remove: eachVersionName ] ] ] ]. > - ^ missing isEmpty or: > - [ self selectDependency: missing anyOne. > - self confirm: > - (String streamContents: > - [ : strm | strm > - nextPutAll: 'No repository found for' ; > - cr. > - missing do: > - [ : r | strm > - nextPutAll: r ; > - cr ]. > - strm nextPutAll: 'Do you still want to store?' ]) ]! > > Item was changed: > ----- Method: MCConfigurationBrowser>>store (in category 'actions') ----- > store > + (self checkRepositories and: [ self checkDependencies ]) ifFalse: [ ^ self ]. > + self pickName ifNotNil: > + [ : name | self configuration name: name. > + self pickRepository ifNotNil: > + [ : repo | repo cacheAllFileNamesDuring: > + [ self configuration dependencies do: > + [ : each | repo > + versionWithInfo: each versionInfo > + ifAbsent: [ repo storeVersion: (MCRepositoryGroup default versionWithInfo: each versionInfo) ] ] ]. > + repo storeVersion: self configuration ] ]! > - (self checkRepositories and: [self checkDependencies]) ifFalse: [^self]. > - self pickName ifNotNil: [:name | > - self configuration name: name. > - self pickRepository ifNotNil: [:repo | > - repo storeVersion: self configuration]].! > >

I just tried it again a minute ago and I still have the problem. If something was done earlier today to fix this it appears not to have worked for me. Note that in my case I just created my project yesterday, apparently between the last save and yesterday's crash. As a result when it restarted and I looked today there was no project, and hence no data in the image about the project at all. I'm assuming that it would have to know about the project to re-harvest the versions. Perhaps I'm wrong about that. Additionally earlier today I recreated the project under the same name. Perhaps that confused the issue? Anyway thanks for the info and if I should email somewhere else please let me know. Ken

SqueakSource.com package import problem
by Ken Causey 22 Aug '11

22 Aug '11

I'm having trouble importing package versions on SqueakSource.com today. Yesterday I created a project called GraphingService and configured it and uploaded 2 package versions. Today I checked to find that the project had disappeared. The result of a crash I suppose, annoying but... So today I am recreating the project and it seems to go fine up until I try to re-import the packages. When I try to do so it complains that there was a problem and specifically that the file I uploaded is not in mcz format. However first of all these are the exact same files I uploaded find yesterday and also I can open them just fine locally and Monticello seems to be fine with them. Note that this are files I uploaded yesterday. Given the little I know about SqueakSource I suspect that the old files are still in the filesystem and I wonder if they are not somehow interfering with this upload. Thanks, Ken

Hi, i just encountered a fixed price job on elance. Somebody needs a video game developer. Targetplatform may be Java, Squeak, Smalltalk or Python: http://www.elance.com/j/video-game-developer/25782784/ Maybe someone is interested to do this in Squeak before it will be done in Java ... I'm in no affiliation to the provider of that project. regards, Stefan -- http://krecher.com • http://twitter.com/stefcom https://www.xing.com/profile/Stefan_Krecher • http://www.facebook.com/krecher http://www.google.com/profiles/stefan.krecher
