The example in the comment now blocks the UI... I'm attaching a simplified version of the previous proposal just in case... but frankly, I barely know what I'm doing... it's so interrelated and I can't foresee possible impact of even a small change, sorry if I missed something.<o:p></o:p> <o:p> </o:p> One more question: in your previous update #5346 you changed the return value from UIProcess to oldUIProcess: I can't figure out why... in case you have a spare minute :)<o:p></o:p> <o:p> </o:p> > [...] it is no longer possible to have 2 different worlds running in different processes. <o:p></o:p> > Well the UIProcess class variable already precludes this. When we work on enabling multiple worlds, each with its own running process, we'll see.<o:p></o:p> <o:p> </o:p> yes, that's what I thought... no harm done at the moment; later, each world might need to have it's own "UIProcess" variable.<o:p></o:p> <o:p> </o:p> Thanks again,<o:p></o:p> best,<o:p></o:p> Jaromir<o:p></o:p> <o:p> </o:p> <o:p> </o:p> <div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"> From: <a href="mailto:JuanVuletich@zoho.com">Juan Vuletich</a> Sent: Monday, July 4, 2022 22:43 To: <a href="mailto:cuis-dev@lists.cuis.st">Discussion of Cuis Smalltalk</a> Cc: <a href="mailto:JuanVuletich@zoho.com">Juan Vuletich</a>; <a href="mailto:mail@jaromir.net"> Jaromir Matas</a> Subject: Re: [Cuis-dev] FW: Freezing UI - can't interrupt via Alt+.<o:p></o:p> </div> <o:p> </o:p> On 7/4/2022 5:38 PM, Juan Vuletich via Cuis-dev wrote: <o:p></o:p> <blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"> On 7/4/2022 5:01 PM, Juan Vuletich via Cuis-dev wrote: <o:p></o:p> <blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"> On 7/4/2022 4:47 PM, Jaromir Matas via Cuis-dev wrote: <o:p></o:p> <blockquote style="margin-top:5.0pt;margin-bottom:5.0pt"> Hi Juan,<o:p></o:p> I’m attaching a changeset that would evaluate the following examples identically, i.e. regardless of whether the code runs in the UI or a non-UI process (simulated by wrapping into fork); please let me know what you think if you find some time.<o:p></o:p> <o:p></o:p> s := Semaphore new.<o:p></o:p> [[1/0] ensure: [s signal]] fork.<o:p></o:p> s wait.<o:p></o:p> self error: 'error'<o:p></o:p> <o:p></o:p> [s := Semaphore new.<o:p></o:p> [[1/0] ensure: [s signal]] fork.<o:p></o:p> s wait.<o:p></o:p> self error: 'error'] fork<o:p></o:p> <o:p></o:p> I’m still just trying to analyze what is a reasonable requirement as for the semantics and the suggested code I just a rough idea for your review; I don’t have enough experience to see the bigger picture.<o:p></o:p> <o:p></o:p> Thanks a lot,<o:p></o:p> jaromir<o:p></o:p> <o:p></o:p> --<o:p></o:p> Jaromír Matas<o:p></o:p> <a href="mailto:mail@jaromir.net">mail@jaromir.net</a><o:p></o:p> </blockquote> Hi Jaromir, This code doesn't account for what I said when you were writing this message ( :) !!! ), but it doesn't add complexity, it is perhaps more robust, and could be of use for some use case I can't foresee. I'll integrate it, with a little change to improve readability, but keeping your authorship. Thanks a lot,<o:p></o:p> <pre>-- </pre> <pre>Juan Vuletich</pre> </blockquote> Done. Now, when scheduling a new Morphic process there's no need to remember to terminate the old one. Gosh, as I write this I now realiza that it is no longer possible to have 2 different worlds running in different processes. Mhhhh. Back to the drawing board. Thanks, <o:p></o:p> <pre>-- </pre> <pre>Juan Vuletich</pre> </blockquote> Well the UIProcess class variable already precludes this. When we work on enabling multiple worlds, each with its own running process, we'll see. I'll leave it there for now.
