<p class="MsoNormal">Hi Marcel, all,</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Jakob spotted an issue with Squot after introducing the revised #suspend semantics (prim 578) and the latest version of #terminate.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I found a pattern in Squot where you suspend and resume a process: if the process was on a semaphore the new #suspend semantics would change the behavior of the computation; however we don’t know yet whether this is the cause of Squot’s
issue.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The same pattern:</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"> oldUIProcess suspend.</p>
<p class="MsoNormal"> Project resumeProcess: oldUIProcess.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">is used in InstallerSqueakMap >> #update so I wonder whether this might be an issue too. I have no experience with SqueakMap and don’t know how to find out whether InstallerSqueakMap >> #update works as intended or whether a fix is necessary;
could possibly somebody experienced verify?</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The fix should be straightforward: use #suspendAndUnblock instead of #suspend to revert to the previous semantics (prim 88) in this particular case.</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks for your help.</p>
<p class="MsoNormal">Best,</p>
