[squeak-dev] The Trunk: Tools-eem.1016.mczcommits at source.squeak.org commits at source.squeak.orgSat Nov 14 05:11:33 UTC 2020
Eliot Miranda uploaded a new version of Tools to project The Trunk: http://source.squeak.org/trunk/Tools-eem.1016.mcz ==================== Summary ==================== Name: Tools-eem.1016 Author: eem Time: 13 November 2020, 9:11:29.559774 pm UUID: 2bb4d3c0-32cd-49c7-b9c5-f04bed33c416 Ancestors: Tools-mt.1015 Have the ProcessBrowser maintain a stackDepth variable and allow moreStack to grow it by a factor of two (we can add lessStack too). fullStack can be dangerous for very deep stacks. Also allow the ProcessBrowser to suspend the UI propcess, spawning a new one if it does so. being able to suspend the UI process is a very useful facility I need right now in debugging the multi-threaded VM. =============== Diff against Tools-mt.1015 =============== Item was changed: Model subclass: #ProcessBrowser + instanceVariableNames: 'selectedProcess selectedContext methodText processList processListIndex stackList stackListIndex stackDepth sourceMap selectedClass selectedSelector searchString autoUpdateProcess lastUpdate startedCPUWatcher' - instanceVariableNames: 'selectedProcess selectedContext methodText processList processListIndex stackList stackListIndex sourceMap selectedClass selectedSelector searchString autoUpdateProcess lastUpdate startedCPUWatcher' classVariableNames: 'Browsers SuspendedProcesses WellKnownProcesses' poolDictionaries: '' category: 'Tools-Process Browser'! !ProcessBrowser commentStamp: '<historical>' prior: 0! Change Set: ProcessBrowser Date: 14 March 2000 Author: Ned Konz email: ned at bike-nomad.com This is distributed under the Squeak License. Added 14 March: CPUWatcher integration automatically start and stop CPUWatcher added CPUWatcher to process list menu Added 29 October: MVC version 2.8, 2.7 compatibility rearranged menus added pointer inspection and chasing added suspend/resume recognized more well-known processes misc. bug fixes Added 26 October: highlight pc in source code Added 27 October: added 'signal semaphore' added 'inspect receiver', 'explore receiver', 'message tally' to stack list menu added 'find context', 'next context' to process list menu added 'change priority' and 'debug' choices to process list menu 27 October mods by Bob Arning: alters process display in Ned's ProcessBrowser to - show process priority - drop 'a Process in' that appears on each line - show in priority order - prettier names for known processes - fix to Utilities to forget update downloading process when it ends (1 less dead process) - correct stack dump for the active process !
