[Pharo-project] latest update #10129 breaks FileList2 (NonBooleanReceiver: proceed for truth).

by John M McIntosh

After updating my test image and then attempting to open a file list browser I get a walkback This seems to be related to a change in FileList2>>initialize where showDirsInFileList _ false. was dropped by lr 10/29/2008 21:28 Unfortunately showDirsInFileList is not initialized anywhere else so the block then which uses the variable evaluates to nil... -- = = = ======================================================================== John M.

Re: [Pharo-project] Too much updates without an image

by Adrian Lienhard

I found the problem. Its a quite complex bug, actually, as it is not related to the update #120 but to #116. I inadvertently introduced the problem with the memory clean up script. It resets the update downloader, and this makes the update queue to get into an inconsistent state after consuming 5 more updates. This is why we did not see the problem earlier but only now that we update from 116 through to 120. I don't have time to fix that now, but I will try this evening.

Again: a newcomer to Pharo is not necessarily a newcomer to Smalltalk or Squeak. I am a case in point: I intermittently dabbled with Squeak, so I have a rough knowledge about the "kid stuff" living in the image. A clear statement that this (for me) irrelevant stuff and its supporting cruft is removed, is a plus. Just making Smalltalk, s.

I have prepared something on the wiki (not yet complete): http://code.google.com/p/pharo/wiki/GettingStartedWorkspaces I'm planning to move more of Torsten's text there. As of now it is in Wiki markup, so it is easier to edit / discuss. Later on one could convert that to in-workspace text automatically.
