Case 5959 - Broken process resume interaction with waiting semaphore

by Ben Coman

I went looking at the oldest cases, and found issue 5959 interesting and perhaps within my scope for my first foray into the VM. On build 40360 with the following test script... | sema proc | Transcript clear. sema := Semaphore new. proc := [ sema wait. Transcript crShow: 'signalled' ] proc priority: Processor highestPriority . proc resume. proc suspend. Transcript crShow: 1. proc resume. Transcript crShow: 2. sema signal. Transcript crShow: 'excessSignals=' ; show: sema excessSignals Prior loading attached changeset gives... 1 signalled 2 excessSignals=1 After loading attached changeset gives... 1 2 signalled excessSignals=0 btw, for the test script you need to add Semaphore>>excessSignals ^excessSignals The changeset loads on top of VMMaker updating: * CoInterpreterPrimitives>>primitiveSuspend * CoInterpreterPrimitives>>primitiveResume Now I probably have abused myList to keep the semaphore for primitiveResume to reactive, but I did poke around references to MyListIndex and it seemed myList was written to more than read from. ----------- In the issue there was mention that some libraries may rely on the broken semantics. Anyone know which those might be? cheers -ben https://pharo.fogbugz.com/default.asp?5959 'From Pharo3.0 of 18 March 2013 [Latest update: #30860] on 19 November 2014 at 12:59:04.381324 am'! !CoInterpreterPrimitives methodsFor: 'process primitives' stamp: 'BenComan 11/19/2014 00:34'! primitiveResume "Put this process on the scheduler's lists thus allowing it to proceed next time there is a chance for processes of it's priority level.

SciSmalltalk already provide the following basic functionalities: - complex and quaternions extensions, - random number generators, - fuzzy algorithms, - Didier Besset's numerical methods, - Ordinary Differential Equation (ODE) Solver. Version 0.16 includes updates from Werner Kassens to several packages, the work Nicolas Cellier about arbitrary precision floats. SciSmalltalk project web page is here: https://github.com/SergeStinckwich/SciSmalltalk All the code is available under the MIT licence. We have more than 563 green unit tests and we run a CI job here: https://ci.inria.fr/pharo-contribution/job/SciSmalltalk/ This version should work on Pharo 3.0/4.0 and also Squeak 4.5 (to be confirmed). We are looking for more code contributions and also tests, documentation !
