ESUG deadline for Presentation
by stephane ducasse June 3, 2022

June 3, 2022

Hi Happy Smalltalkers Two important points - We are starting to work on the program of ESUG 2022 and we will accept some more talks but do not wait too long. https://esug.github.io/2022-Conference/call2022.html <https://esug.github.io/2022-Conference/call2022.html> - The registration is open and the early rate is nicer than the late one :) https://registration.esug.org <https://registration.esug.org/> But you can sponsor ESUG by registering with late fees from 6th of July. But this is more expensive. S

Summary: SelectorTable improvements
by Marcus Denker June 3, 2022

June 3, 2022

Hi, Here is a short summary of all the improvements related to the SelectorTable (which allows the tools to quickly check if a symbol is used as a selector): - It is reset at image build (#cleanUp) - re-creating is fast (#bench shows '16.902 per second' on my machine for rebuildSelectorTable) (we can even think about resetting it on #shutDown: now) - Recording happens at method installation, not compilation - this means we call it far less on code loading - not called anymore for doIts and FFI method creation - optimized: #isSelectorSymbol is ~3.5 times faster in Pharo11 compared to Pharo10 - most speedup due to using a identity dictionary, avoiding costly string comparing - all users of #findInternedSelector: have been changed to send #isSelectorSymbol to the symbol - #findInternedSelector: will be deprecated Marcus

[Issue Tracker] issues with proposed fixes
by Marcus Denker June 2, 2022

June 2, 2022

Hi, Sometimes it happens that a *description* of a fix is added to the issue tracker entry. We try to tag them with âFix Proposed" https://github.com/pharo-project/pharo/labels/Fix%20proposed <https://github.com/pharo-project/pharo/labels/Fix%20proposed> In practice, it is either astonishingly hard to turn a description into a fix, or it is so trivial that it feels as if nothing has to be done. (It feels sometimes that finding the solution is the real contribution, while actually doing it feels like boring work). - add, if possible, the code of the whole changed method, too (I often wonder if it is all correct after doing the steps described by a textual description, especially if the method got changed in between) - Make it *really* clear in the issue tracker entry that a fix has been proposed. Sometimes it gets lost in the discussion. - Doing a PR from an issue that already has a description is very valuable This can a nice way to contribute for beginners. âIt donât understand if it is good, but I made a PR for the solution described in the issue" Marcus
