Lukas, You are correct to question "what is Pharo?" We cannot hope to ensure that everything anyone ever does with Pharo will work - those kinds of promises are made only during political campaigns :) But, note the recent discussion of package integrity. It should be as easy as possible to install anything one wants, but the things that Pharo invites the user to install should be solid. Certainly, the development tools should fall into that category. For example, I have a love/hate relationship with the RB, but I certainly hope to see it integrated into Pharo. But given a choice between a polished presentation of the RB commands and a stable system, I'll go for the stable system. We should have both. Bill Wilhelm K.

Lukas, My understanding is that the OB tool set is the presumptive choice for Pharo - unless I'm wrong, that makes this a Pharo related topic, if only to reopen the choice in light of your position. Do as you want, but Object Arts had this idea and very quickly decided the simpler notifier had a very essential role. They left the option, activated the notifier by default, and strongly warned against deactivating it. That was based on being bitten by the kinds of concerns I have documented here. Bill Wilhelm K.

That would be better than the current situation, but, among other questions I'm probably not going to think of, it might be easy to decide how many debuggers are open when the error occurs, but how many are trying to open? Maybe a shared queue would suffice. Anyway, I get a vote, and it's in favor of notifiers; if there is further a preference to skip that step, that's fine by me. Bill Wilhelm K.

Stef, Under ordinary circumstances, it's ok, but OA tried this and then quickly decided it was a bad idea. Imagine a budding recursive chain of errors; the extra load of opening the debugger can prevent a rescue that might be possible given a lightweight notifier. Bill Wilhelm K.

Hi john Gwenael told that: SystemImage current getSystemAttribute: 1 returns well the image name SystemImage current getSystemAttribute: 2 does not return the other arguments passed Apparently this is working under linux. Then apparently when he launches the vm from the command line he cannot click but the mouse scrolling works. I asked to send a report but he is away. So sorry for the fuzzyness of my report. I prefer to report is than to forget. He will complement it if you need more info Stef

[Pharo-project] Notifiers

Dec. 20, 2008

Hello all, One change I do not like is that errors bring up a debugger vs. starting with a notifier. Beyond a "we fear change" <g> reaction, it can get expensive if things are bad enough to create errors in rapid succession. Is there a preference I can set to get the previous behavior?

Stef, This appears to be deliberate in the new OB tools. I'm all for it as a preference, but recommend disabling it as a default - it's a long way from error to open debugger, so a safe landing along the way is a good idea IMHO. Bill Wilhelm K.
