Introducing silent_stream

ActiveSupport’s Stream Silencing - Without ActiveSupport SilentStream is an extraction of some parts of ActiveSupport’s Kernel Reporting Core Extentions. Since July 2014 silence_stream, silence_stderr, capture, silence, and quietly have been deprecated because they are not thread safe. See that discussion in the PR where it all went down. I rely on them a lot in single threaded code, and so I plan to keep them alive. With the exception of silence, which was just an alias of capture.

Introducing anonymous_active_record

ActiveRecord Without a Database? Replacement for broken Class.new(ActiveRecord::Base). Very useful in testing Rails apps, and even more so for testing gems without having to specify full blown models.

Maintaining oauth2

A Ruby wrapper for the OAuth 2.0 protocol UPDATE 2018-10-13: Version 1.4.1 has been released! I am now the lead maintainer of the oauth2 gem. I will work toward getting a version 2.0.0 released, which will not drop support for any currently supported Rubies. After that a 3.0.0 release will drop support for EOL Rubies. Oauth2 gem is looking for additional maintainers. See #307. A Ruby wrapper for the OAuth 2.

Introducing activerecord-tablefree

ActiveRecord Without a Database? ActiveRecord Tablefree Models provides a simple mixin for creating models that are not bound to the database. This approach is useful for taking advantage of the features of ActiveRecord such as validation, relationships, nested_attributes, etc. This can also be very useful in testing where a mock-like object will suffice. This gem is exceptionally hacky. For an alternative solution, primarily aimed at testing, that is less hacky, see my other gem anonymous_active_record!

Introducing resque-unique_at_runtime

Ensures that only one job for a given queue will be running concurrently. A semanticaly versioned Resque plugin which ensures for a given queue, that only one worker is working on a job at any given time. Resque::Plugins::UniqueAtRuntime differs from resque-lonely_job in that it is compatible with, and can be used at the same time as, resque-solo. Resque::Plugins::UniqueAtRuntime differs from resque_solo in that resque-solo offers queue-time uniqueness, while resque-unique_at_runtime offers runtime uniqueness.

Gemfile Specs! New for gem_bench v1.0.2

Gemfile Specs! New for 1.0.2 Version constraints are important. Give the Gemfile some love in your CI build Create a spec/gemfile_spec.rb like: Rspec.describe "Gemfile" do it("has version constraint on every gem") do requirements = GemBench::StrictVersionRequirement.new({verbose: false}) expect(requirements.list_missing_version_constraints).to eq([]) end end Then your build will fail as soon as a gem is added without a proper constraint: Failures: 1) Gemfile has version constraint on every gem Failure/Error: expect(requirements.list_missing_version_constraints).to eq([]) expected: [] got: ["puma"] (compared using ==) # .

Introducing resque-unique_by_arity

Magic hacks which allow integration of job multiple Resque plugins providing different types of job uniqueness Because some jobs have parameters that you do not want to consider for determination of uniqueness. resque_solo and resque-unique_at_runtime (a resque-lonely_job rewrite) will now work together! Without this gem they are fundamentally incompatible. I’ll put something here soon.
