Re: [Pharo-dev] Traits methods flattened

Epicea browser not starting when image is crashed

by Rajula Vineet

The method openBrowserIfLostChanges in the class EpLostChangeDetector not opening the Epicea browser when the image is crashed. I have tried the following. I changed a method, deleted some comment and I quit without saving. Epicea did not open. I also tried crashing the image using Ctrl+C. But the Epicea browser didn`t open. I also tried adding a new method, and quitting without saving. Versions: Pharo version 6.0 Image version #60649 VM Version vmLatest60 -- View this message in context: http://forum.world.st/Epicea-browser-not-starting-when-image-is-crashed-tp4… Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Yes, this is the reason. In the case of Epicea in the latest image, the last version is 8.1.3, but ConfigurationOfEpicea>>#currentVersion returns 7.8p4. 7.8p4 is the highest version for which there is a dependency on the STON project, dependency which is respected in the image (version requested is 0.17, version present is 0.23). 7.8p4 and all higher versions also have a dependency on Smark, which isn't loaded. Would that mean that: - If one of the project in requirements is present in the image, then the version is considered current (here, for 7.8p4, Ston is present, Smark is not) if, for the packages of the project, all are present with versions higher than the current configuration version spec? - If none of the projects in requirements are present in the image, then the version is not considered current (in 8.1.3, Smark is not present but I see no dependency on Ston[*]) ? I have a feeling this is a strange result, and I'd prefer 8.1.3 to have the same validity as 7.8p4. Is this MetacelloProject>>#currentVersion used to determine if a project should be upgraded? Another question, related to the original topic: if the current configurations in the image are in this state, is it a good idea to leave them in? Would it have a chance of triggering incorrect updates or suspicious errors[**] if we start using them to load Metacello projects that depends on them?
