Cheap/free Seaside site hosting (urgent)?
by lucasrodriguesoficial5＠gmail.com June 22, 2022

June 22, 2022

Hello there. Iâve just finished a website which, aside from a simple storage in Mongo/Voyage permanence layer, is otherwise very small and simple. But Seaside Hosting and Pharo Cloud are down, and international transactions are impossible in Digital Ocean. My country doesnât have any of the less complex cloud storages, making it all more difficult. At this point, Iâm willing to pay 17 dollars (max I have now) so that someone sets the image up for me at a DO droplet only once, as the app is technically static. This is urgent because the site is an effort to find a job (as a portfolio), and I donât have any additional money for nothing fancier. If no one can do that, what are the alternatives?

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

[ Review needed] Some easy to review PRs

Some easy to review small improvements (which in turn makes them easier to review): 1) use #isSelectorSymbol instead of #findInternedSelector: https://github.com/pharo-project/pharo/pull/11313 2) Improve: Symbol class>>#internSelector: can just record the symbol https://github.com/pharo-project/pharo/pull/11315 3) optimize MorphExtension>>#valueOfProperty: a little https://github.com/pharo-project/pharo/pull/11314 Marcus

Question about MethodDictionary in TraitedClass (methodDict/localMethodDict)
by Andrei Chis May 30, 2022

May 30, 2022

Hi, We were profiling the loading of code that uses many Traits. We saw something like this (this is a tally for `TraitedMetaclass>>#addAndClassifySelector:withMethod:inProtocol:`): [image: Screenshot 2022-05-11 at 17.17.37.png] >From what we saw in `TraitedMetaclass>>#addAndClassifySelector:withMethod:inProtocol:` a method is first added to `localMethodDict` and then it calls the super method that adds the selector to the `methodDict` of the actual class in `Behaviour>>addSelectorSilently:withMethod: `. Because of this we basically get an overhead as a method is added to two method dictionaries and adding a method to a MethodDictionary is slower, as it does operations like `flushCache` and `cachePragmas`. Should the `localMethodDict` also be an instance of MethodDictionary or could it be a simple dictionary? Cheers, Andrei
