This week (10/2022) on the Pharo Issue Tracker

by Marcus Denker

We merged 3 PRs and fixed 4 Issue tracker entries. Especially #10972 is important: with this the bug that lead to an overly huge image size is fixed. Now one can actually see that Pharo10 is smaller than Pharo9 due to: - code cleanup: removal of dead code, simplifications, cleanups - sharing of literals across all methods as part of the image build - first small improvement of size of the data structures of the code (related to Protocol) (much more possible here, but it has to wait for Pharo11) There are more PRs ready for Pharo10 that just need a review to be merged: https://github.com/pharo-project/pharo/pulls Fixes ==== 10667-Installed-breakpoints-not-shown-in-UI-after-AST-cache-reset-during-image-saving #10962 https://github.com/pharo-project/pharo/pull/10962 ensure no literal is kept pinned in memory when building an image #10972 https://github.com/pharo-project/pharo/pull/10972 Extend class comment of Dictionary #10973 https://github.com/pharo-project/pharo/pull/10973

[ANN] UTF8String

by Sven Van Caekenberghe

Hi, I recently revised some code that I wrote in 2019 and prepared it for publication. UTF8String is a proof of concept / prototype alternative String implementation for Pharo using a variable length UTF8 encoded internal representation. There is a writeup with more details in the README on GitHub: https://github.com/svenvc/UTF8String The public methods are commented and there are some basic unit tests. Just like the experiment of a SubString class that is just a [from,to] pair on an existing (readonly) String (which I believe someone once did, but I can't remember the details), this is another idea that might maybe one day be useful.

Re: Migration of ReferenceFinder

by pmissech

Oh, I was not aware. I have been loading it every time I've needed it from the smalltalkhub directory ! I guess i'll remove the repository then, issues for it should probably be on the Pharo repository !

The ReferenceFinder class is the one I wrote for the Refactoring Browser and then converted to Pharo. It is under the MIT license. It is already part of the Pharo image (https://github.com/pharo-project/pharo/tree/Pharo10/src/ReferenceFinder-Core) John Brant > On Feb 27, 2022, at 10:03 PM, Pierre Misse Chanabier <pierre.misse-chanabier(a)inria.fr> wrote: > > I'm assuming you're talking about https://github.com/pavel-krivanek/RefsHunter ? > (That's the only one I saw on Pavel's account) > > From a quick look, it seems like a different implementation which rely on a snapshot of the memory. > But I haven't looked very deep at all. > > Pierre > > On 2/27/2022 9:23 PM, stephane ducasse wrote: >> Thanks Pierre >> Do you know how it compares with the port of Pavel Krivanek? >> >> S >> >>> On 25 Feb 2022, at 15:20, pmissech <pierre.misse-chanabier(a)inria.fr> wrote: >>> >>> Hello, >>> >>> I've migrated the small repository of Reference Finder to github: https://github.com/hogoww/ReferenceFinder/ from Smalltalk-hub. >>> If someone is aware of another migration of the repository, licensing or others, please let me know. >>> >>> Pierre
