[ruby-talk:444168] gem mysql2 ruby 32, mysql server 8.0
by Tom Reilly 27 Mar '23

27 Mar '23

I've been able to use gem mysql2 and an older version of ruby without any problem. Updating both programs I've not been able to get them to work even though I have gone through everything I could find on the internet. With all the posts that mysql2 doesn't work is there another gem other than mysql2 that works? Is there something obvious that i am missing?

[ruby-talk:444163] [ANN] minitest 5.18.0 Released
by Ryan Davis 04 Mar '23

04 Mar '23

minitest version 5.18.0 has been released! * home: <https://github.com/seattlerb/minitest> * bugs: <https://github.com/seattlerb/minitest/issues> * rdoc: <https://docs.seattlerb.org/minitest> * vim: <https://github.com/sunaku/vim-ruby-minitest> * emacs: <https://github.com/arthurnn/minitest-emacs> minitest provides a complete suite of testing facilities supporting TDD, BDD, mocking, and benchmarking. "I had a class with Jim Weirich on testing last week and we were allowed to choose our testing frameworks. Kirk Haines and I were paired up and we cracked open the code for a few test frameworks... I MUST say that minitest is *very* readable / understandable compared to the 'other two' options we looked at. Nicely done and thank you for helping us keep our mental sanity." -- Wayne E. Seguin minitest/test is a small and incredibly fast unit testing framework. It provides a rich set of assertions to make your tests clean and readable. minitest/spec is a functionally complete spec engine. It hooks onto minitest/test and seamlessly bridges test assertions over to spec expectations. minitest/benchmark is an awesome way to assert the performance of your algorithms in a repeatable manner. Now you can assert that your newb co-worker doesn't replace your linear algorithm with an exponential one! minitest/mock by Steven Baker, is a beautifully tiny mock (and stub) object framework. minitest/pride shows pride in testing and adds coloring to your test output. I guess it is an example of how to write IO pipes too. :P minitest/test is meant to have a clean implementation for language implementors that need a minimal set of methods to bootstrap a working test suite. For example, there is no magic involved for test-case discovery. "Again, I can't praise enough the idea of a testing/specing framework that I can actually read in full in one sitting!" -- Piotr Szotkowski Comparing to rspec: rspec is a testing DSL. minitest is ruby. -- Adam Hawkins, "Bow Before MiniTest" minitest doesn't reinvent anything that ruby already provides, like: classes, modules, inheritance, methods. This means you only have to learn ruby to use minitest and all of your regular OO practices like extract-method refactorings still apply. Changes: ### 5.18.0 / 2023-03-04 * 2 major enhancements: * Added assert_pattern & refute_pattern for pattern matching. (flavorjones) * Added matching must_pattern_match & wont_pattern_match to minitest/spec. * 1 bug fix: * Support the new message format of NameError in Ruby 3.3 (mame)

[ruby-talk:444162] [ANN] ruby_parser 3.20.0 Released
by Ryan Davis 04 Mar '23

04 Mar '23

ruby_parser version 3.20.0 has been released! * home: <https://github.com/seattlerb/ruby_parser> * bugs: <https://github.com/seattlerb/ruby_parser/issues> * rdoc: <http://docs.seattlerb.org/ruby_parser> ruby_parser (RP) is a ruby parser written in pure ruby (utilizing racc--which does by default use a C extension). It outputs s-expressions which can be manipulated and converted back to ruby via the ruby2ruby gem. As an example: def conditional1 arg1 return 1 if arg1 == 0 return 0 end becomes: s(:defn, :conditional1, s(:args, :arg1), s(:if, s(:call, s(:lvar, :arg1), :==, s(:lit, 0)), s(:return, s(:lit, 1)), nil), s(:return, s(:lit, 0))) Tested against 801,039 files from the latest of all rubygems (as of 2013-05): * 1.8 parser is at 99.9739% accuracy, 3.651 sigma * 1.9 parser is at 99.9940% accuracy, 4.013 sigma * 2.0 parser is at 99.9939% accuracy, 4.008 sigma * 2.6 parser is at 99.9972% accuracy, 4.191 sigma * 3.0 parser has a 100% parse rate. * Tested against 2,672,412 unique ruby files across 167k gems. * As do all the others now, basically. Changes: ### 3.20.0 / 2023-03-04 * 1 major enhancement: * Added tentative 3.2 support. * 1 minor enhancement: * Change minimum ruby version to 2.6. (want higher) * 1 bug fix: * Fix up compare tasks for ruby 3.2 differences.

[ruby-talk:444157] Fixing Ruby gems installation part 2
by Felipe Contreras 01 Mar '23

01 Mar '23

Hi, This is the second part of my attempt at fixing gem installation, it's necessary because it's *not yet fixed*. https://felipec.wordpress.com/2023/02/27/fixing-ruby-gems-installation-part… The maintainers of rubygems continue to ignore my solution, despite being the only one that actually works. The patch is really simple: https://github.com/felipec/rubygems/commit/68c0127885bc80761eb948963f9d5733… And I created an Arch Linux package with the patch and proper overrides: https://aur.archlinux.org/packages/rubygems-user It works perfectly. It has been *twelve years* since the first issue regarding this was reported, hopefully it will get fixed before the end of this decade (could be fixed now if the maintainers simply applied my patch). Cheers. -- Felipe Contreras

[ruby-talk:444139] [ANN] Learning by Reversing: Native Gems, Parts 1 and 2
by Mohit Sindhwani 01 Mar '23

01 Mar '23

Hi Everyone, For a long time, I wanted to do a series of posts called "Learning by Reversing" where I look at something that exists and is useful, and try to work back and explain it. For this, my first series is about Native Gems in Ruby. So, I've picked a simple native Ruby gem called fast-polylines and am looking at all the code, how to develop it, how to test it, how it loads, how it works, etc. with the aim of helping people understand Native Ruby gems better. The first 2 parts are now online on my blog: * Part 1 - This covers the background to the gem we explore Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e1-native-gems/ * Part 2 - This goes into the details of how ruby loads the native gem and extension (and includes a nice sequence diagram of how all the bits happen together) Link: https://notepad.onghu.com/2023/learning-by-reversing-s1-e2-native-gems/ Future posts are planned to go into details like: * The interface between Ruby and C * The Makefile * A Makefile that also works on Windows * Running the specs * Running the performance benchmark * Enhancements: - Providing an executable - A gem that also works on JRuby - Making the gem ractor friendly - Patching an existing gem rather than a new module Comments on the posts or the plans welcome. Best regards, Mohit.

[ruby-talk:444156] Re: How to load ruby-openssl headers in a C extension
by Tiago Cardoso 27 Feb '23

27 Feb '23

Hi, thx for the suggestion. Unfortunately, it doesn't work with a bundled gem, at least in a mac: gems get distributed in .bundle packages, so: ```ruby spec = Gem::Specification.find_by_name("openssl") source_dir = File.join(spec.full_gem_path) Dir.glob(source_dir + "/*/**") => [] # ruby-install installs bundled gem extensions under /Users/tiagocardoso/src/ruby-3.2.1/.ext/x86_64-darwin21/ ``` I believe that Frank may be correct here, in that "openssl" does not declare its header files as external in extconf.rb .
