Pharo 8 Image blows up after restart
by Sabine Manaa Dec. 9, 2020

Dec. 9, 2020

Hi, I have the following problem: sometimes, after restarting my Pharo 8 image on mac, it is not responsive and it blows up the memory. I tried with commandline handler eval "self halt" and with Smalltalk addToStartUpList: but both is too late - the Image starts and blows up and is not responsive. I can not interrupt it and it grows to several GB memory (eg after 20 seconds 10 GigaByte! ) and I have to kill it. Anyone having an idea what I can do to find the reason for this?

This week (49/2020) on the Issue Tracker
by Marcus Denker Dec. 7, 2020

Dec. 7, 2020

Spec v0.5 ========== New Inspector is now default in Pharo! - Inspector Introduces concept of "inspection concept" which allows to configure how the presentation will be show (and if it will be shown). For now it does not do much, but potential is huge. - Inspector uses SpMillerPaginatorPresenter. - Inspector uses popover to allow command expansion in the toolbar (otherwise is too big). - Inspector panes are closeable now. - Inspector, Playground now understand <meta+g> command - Playground pages now can "open in new page". - Activation in single click (which triggers column expansion) is now default for inspections (it was double click, but it felt weird). - Added several inspections (extensions to objects) to match what we had before. - Most commands now delegate its behavior to their contexts to allow better handling of them. - Introduce "icon providers" to handle how icons are provided in applications. - Refactor the way icons are used in StPharoApplication to allow switching of icon sets and the gradual transition from current naming to a better, semantic way of name icons. - Fixes #128 - Fixes pharo-project/pharo#7700 - Fixes #123 - Several bugfixes. Small Speed Improvements ======== Some tiny improvements, but the morph related code (like #hasDropShadow) is called in the main rendering loop. - optimize-hasDropShadow #7917 https://github.com/pharo-project/pharo/pull/7917 - Cleanup code for Morph properties #7903 https://github.com/pharo-project/pharo/pull/7903 - Do not allocate a block when executing #isInstalled #7936 https://github.com/pharo-project/pharo/pull/7936 Fixes ===== - Fix #7898 #7918 https://github.com/pharo-project/pharo/pull/7918 - Fix infinite recursion upon send of not-understood message to nil #7902 https://github.com/pharo-project/pharo/pull/7902 - [fix] fixes selector extraction when asking for it at the first charaâ¦ #7881 https://github.com/pharo-project/pharo/pull/7881 Improvements / New Features =========================== - Improve-isHaltNode #7919 It was detecting all sends to Halt, now it filters for selectors in the right category there. https://github.com/pharo-project/pharo/pull/7919 - Implementing hasProperty in Behavior and RPackage. #7875 https://github.com/pharo-project/pharo/pull/7875 - Add ExternalAddress class>>#allocate:bytesDuring: #7727 https://github.com/pharo-project/pharo/pull/7727 - No "inconsistent method classification" for methods in deprecated method category #7868 https://github.com/pharo-project/pharo/pull/7868 Cleaning unused Variables ========================= After all vars are cleaned, we will add a ReleaseTest so this can never happen again. - Remove unused ivars from HeuristicCompletion packages #7943 https://github.com/pharo-project/pharo/pull/7943 - Care on unreferenced variables in OpalCompiler packages #7944 https://github.com/pharo-project/pharo/pull/7944 - Remove unused environment ivar from BuilderManifestTest #7940 https://github.com/pharo-project/pharo/pull/7940 - Removed unused instance variable traitDefinition in CDTraitParserTest #7886 https://github.com/pharo-project/pharo/pull/7886 Halt Cleanups ============= There should be no #halt (and similar) sends in the code, Iif it is used for testing, this should be tagged. The goal then is to add a ReleaseTest to make sure the code stays clean. This makes the "Browse Breakpointsâ feature more usable, too - tag more tests with <haltOrBreakpointForTesting> #7926 https://github.com/pharo-project/pharo/pull/7926 - 7927-halt-left-in-OmBlockrefreshIfNeededStartingAtsince #7931 https://github.com/pharo-project/pharo/pull/7931 Cleanups: remove Code ====================== - 7830-DummyFindReplaceService-not-documented-not-used-Can-be-removed #7891 https://github.com/pharo-project/pharo/pull/7891 - Remove DeprecatedFileStream package #7885 https://github.com/pharo-project/pharo/pull/7885 - shouldDisplayOnTopContext-seems-to-be-not-needed #7873 https://github.com/pharo-project/pharo/pull/7873 Cleanups ======== And again lots of small cleanupsâ¦ think about them not as how important one of them is.

[ANN] New inspector as default in your Pharo9 image!
by Esteban Lorenzano Dec. 3, 2020

Dec. 3, 2020

Hi all, Today we are introducing our new inspector based on NewTools. This is part of our effort to replace all old tools (some based on Glamour, some based on Spec1 and some others in plain Morphic) to meet same design guidelines and prepare them for the future of the Pharo IDE. Next weeks we will integrate the new Spotter, which will be the end of the Glamour migration effort. Some work on migrating Iceberg and other Spec1 tools are on its way (and they will be merged as soon as work reach beta status) The most important changes for the new inspector are the inclusion of object-centric breakpoints, that apply only for the inspected object: - Right click on any instance variable in the raw view shows a menu to install a breakpoint on accesses to that variable: the execution will break whenever this variable is read, written or both (this is configurable) but only for the inspected object. - Right click on any method in the "Meta" view shows a menu to install a breakpoint on that method: the execution will break when that method is called but only for the inspected object. - The toolbar shows a button to configure a breakpoint on state access for the inspected object: the execution will break whenever any instance variable of the object is accessed (read, write or both and configurable) but only for the inspected object. - The breakpoint pane shows all breakpoints installed for the inspected object and for all other instances of the object's class. Use this pane to deactivate or to uninstall object-centric breakpoints. Cheers! Esteban ps: Yes, there will be bugs (maybe a lot) and missing inspector extensions. I'm counting on you to report (or/and helping implement it)

[ANN] New UI renderer with Hi-DPI support (Beta testing)
by Ronie Salgado Nov. 30, 2020

Nov. 30, 2020

Hello, The last months I have been working in a new UI rendering framework for Pharo based on adding an intermediate scene graph with the purpose of improving rendering speed, and with the side effect of making the whole UI scalable and adding support for Hi-DPI rendering. We would appreciate that people could start testing this so that we can find bugs and stabilize it. For using this the latest Pharo 9 image and headless vm is required. Form Scene Graph repo, installation and settings repository: https://github.com/ronsaldo/form-scene-graph Known issues: - Iceberg is hanging on fetches and pushes only when using the Athens backend. No segmentation fault or debugger is being launched here so this is difficult to fix. When having to deal with this issue we recommend using the OSWindowGenericRenderer backend (SDL2). Best regards, Ronie
