The right answer for FileTree is to re-architect the implementation. The code is currently liberally sprinkled with FileDirectoryisms as FileTree does a lot of directory traversal ... Cami made a pass at replacing the FileDirectory calls with Filesystem calls[1] so I have a good blueprint for building an implementation neutral directory structure traversal class that can isolate the FileDirectory/Filesystem calls into a manageable location (right now there are just too many places that are different) ... So given time (and as I mentioned elsewhere I have to start preparing my ESUG talk because that's a hard deadline) I can get a handle on this. Eventually I plan to port Filesystem to GemStone, so moving away from FileDirectory is in my future plans as well, it's just the timing that is an issue, not the direction. I think that Sport should eventually end up with a port to Pharo-2.0, but for FileTree I don't think I want to require Sport. The FileTree implementation will benefit by the removal of the FileDiretoryisms, so that's the route I will take. [1] https://github.com/dh83/filetree/commit/4232898d4dbdd9712f4276f69c9404e14a6… | 4) Should we integrate Metacello in the image with our changes until | you have time and find a good solution that works everywhere? Maybe | if we do 1) it is not very necessary. If you decide to stick with your decision to drop FileDirectory, then a fork or Metacello will be a good choice for the near term ... you can freely make the most efficient changes to Metacello to keep it running and focus your energies on making Pharo-2.0 better ... I can take my time to port FileTree. If you rename FileDirectory or decide to keep it for a while longer, then I will be able to start immediate work on getting the Metacello Preview running on top of Pharo-2.0 (which shouldn't take too much work)... | | | Thanks for considering this a friendly and positive thread. | It was good that you made a point of focussing on the technical solutions to the problem.

SystemChangeNotification is used in the tests...The tests (obviously) do a whole lot of loading and unloading of packages and suppressing change notifications during some tests has a significant impact on how long it takes to run the tests ... The solution for me is to add some code to the platform packages to hide SystemChangeNotification and use my own variant of silentlyDo: ... The real sticky problem is with FileDirectory...

Re: [Pharo-project] 'self halt' safety net

by Fernando Olivero
