| Summary | 0007345: A VM changes allowing a language-side custom scheduler | |||||||||||
| Description |
This is a changes, which allows Squeak to use image-side scheduling. The VM-side changes is in new-scheduling-for-VM changeset. And image-side changes is in new-scheduling changeset. The image-side changes are safe to file-in into any 3.10 based image (not tested for others). To install a new scheduler , issue: AdvancedProcessScheduler install. Both VM and image side changes are backwards compatible. a) You can use old images with new VM b) You can safely run an image with new scheduler, on older VM - it will fall back to use old ProcessorScheduler. |

A 'new-scheduling-for-VM.2.cs' contains an updated #callbackEnter: method, which should now work correctly with callbacks in new-scheduler-aware image. |

(0013106 - 627 - 716 - 716 - 716 - 716 - 716) sig 05-02-09 02:35 edited on: 05-02-09 02:47 |
- added scheduler regression tests (in scheduling-tests). More recent image-side scheduler (new-scheduling.5.cs) changes: - added an image boot sequence. Now its cleverly picks an appropriate scheduler depending on VM. - a process termination is rewritten, - added a TerminateProcess exception , which could be used to perform additional actions during process termination [ .... ] on: TerminateProcess do: [:ex | .... ] - a process which is being terminated runs as active process. This is to ensure, that any #ensure: / #on:do: / #ifCurtailed: blocks will run in same environment as during normal execution. |
