This week (10/2022) on the Pharo Issue Tracker
by Marcus Denker March 11, 2022

March 11, 2022

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 March 9, 2022

March 9, 2022

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.

[ANN] Pharo Oracle Call Interface
by Sven Van Caekenberghe Feb. 27, 2022

Feb. 27, 2022

Hi, Pharo Oracle Call Interface (https://github.com/Ironirc/Pharo-Oracle-Call-Interface) is a new project that is currently under development. It was started and implemented by Ivo Roefs. This library allows you to connect to an Oracle SQL RDBMS from Pharo (versions 8 and up). It provides a binding with Oracle's OCI (also known as the Oracle Call Interface) using FFI. Usage Once correctly installed on your local computer, you use OciClient to interact with the Oracle database: | client rows | client := OciClient new environmentString: 'pharotst202112_medium'; username: 'SCOTT'; password: 'TIGER'; yourself. rows := client query: 'SELECT * FROM emp'. client close. rows. Installation To install this library you clone the repository and load BaselineOfPharoOracleCallInterface. This can be done using the Iceberg UI tools or with the following script: Metacello new baseline: 'PharoOracleCallInterface'; repository: 'github://Ironirc/Pharo-Oracle-Call-Interface:main/'; load. You have to make sure that the Pharo VM can access/load the necessary native library for your client side OS platform. The easiest way to get started is using Oracle Instant Client and an Oracle Cloud account. You also have to set up and configure access, contact your DBA for help. Status This project is new and currently under development. It should not be used for production applications. Basic queries are working on 32 and 64 bit Windows and 64 bit macOS. We are looking for collaborators, fellow developers who can help. Ivo & Sven
