Thanks! And thanks in general for your tireless documentation efforts. I know it can be a lonely pursuit but is soooo important :) ----- Cheers, Sean -- Sent from: http://forum.world.st/Pharo-Smalltalk-Developers-f1294837.html

I have wanted a clean explanation of semaphores and process scheduling for a long time. Thanks for this.

Hi Stef, here's my review/feedback On Sun, Feb 9, 2020 at 5:05 AM Stéphane Ducasse <stephane.ducasse@inria.fr>

In fig 1.1 there needs to be a back arrow from Executing to Runnable which is labelled "Preempted by a higher priority process" or similar. In the label for fig 1.2 the word "pending" should be replaced with "runnable". Page 8, section "Process Priorities" "At any time only one process is executed." should read "At any time only one process is executing." The line starting "Next table lists..." in the last paragraph on page 8 should read "The following table lists...". The section might want to state some thing like "there that the current implementation of the Pharo scheduler has process priorities from 1 to 100. Only some of these are named. But the programmer is free to use any priority within that range that they see fit." It would be good to include examples which did things like "forkAt: Processor userPriority + 1", etc. In the label for Fig 2.1 "ressources" should read "resources". But throughout that section I would word it that "processes need to share resources", but "the process is waiting to acquire the resource". So use the plural for the general case and the singular for the specific case. Sentences such as this: "P0 has finished to use the resources." should read "P0 has finished using the resource." In Section 2.1 Conclusion "Semaphores are the lower synchronisation mechanisms." should read "Semaphores are the lowest level synchronisation mechanisms." Chapter 3, "Scheduler's Principles" should state that "The Smalltalk scheduler is a real-time, cooperative, preemptive across priorities, non-preemptive within priorities, scheduler." The title to Chapter 4.5 "ShareQueue: a nice semaphore example" should read "Share*d*Queue: a nice semaphore example" Most of the paragraphs on page 49 in section 4.5 are still in French and need translating.
