When it is partially loaded and when World tries to refresh the opened browsers during loading (which I don't know how to avoid), then it might be that the opened browser crashes when trying to refresh as OB is not yet fully loaded and some loaded parts depend on not yet loaded parts. The only solution I see to prevent this is to close all OB browsers when updating it to a new version. In general, but in particular when updating to the version in which I changed the model.

Actually this is what we are doing now, we defer the update until World steps in. See OBCodeBrowser #event:, #noteChanges and #stepAt:in:. Or about what kind of deferring mechanism are you thinking?

In #someClassChanged: post a deferred message to update browser cache, so it will be handled just after file-in will be complete. This works bad, when you compiling code in background process , which having a lower priority than UI process. But in most cases squeak lives & compiling stuff in UI process. I'm not saying its good, but this is what we living with :) > David > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project > -- Best regards, Igor Stasenko AKA sig.

It has two components: One was that the package list is cached and updating of the unpackaged categories is not really possible as they are not first-class entities, so we can't get a notification when they change easily. This problem I fixed by not caching the unpackages categories. There is a second problem though, namely that OB only refreshes when it gets a step signal from World. In the case of file in the step signal doesn't get triggered automatically, so the browser won't update immediately. But after a while it will. Of course we could always update whenever there is a change in the system, but this would lead to a huge performance penalty, particular when loading or fileing in code, so I didn't change that.

[Pharo-project] mac carbon VM Squeak 3.8.20beta1U.app ships for testing.

by John M McIntosh

I've stuck a Squeak 3.8.20beta1U.app.zip file in my EXPERIMENTAL folder found via http://www.smalltalkconsulting.com/squeak.html This test VM contains the latest 32/64 bit integer fetch/set logic & fixes, Alien support and the Alien (IA32ABI) plugin, along with misc fixes to the VM consolidated by Tim and integrated into VMMaker by David T. Lewis in the last few months. If you want to explore Alien then you need this VM and it's plugin to continue. Hint if someone would like to run some benchmarks and compare Alien versus FFI calls that would be good. I note the Alien plugin is macintel only, no powerpc at this time (got funding?) -- = = = ======================================================================== John M.
