Please share some aloha 🌸 for the 27 daring riders who contributed to Rails (and world happiness) this week, including 4 committers who caught their first wave 😍😎! You can, too! Check out the current issues if you'd like to paddle out, make new friends and join the fun 💙
MariaDB is a community-developed open source fork of MySQL. Notable users include Wikipedia, Facebook, Google and, yes, Basecamp 3! Here is a good Wikipedia article about MariaDB and MySQL history. Game on!
Everybody out of the pool! 🏊 It was getting crowded in the water, but luckily our experienced Baywatch lifeguards Matthew, Sean and Jeremy 🏋 were on hand to, er, pool their efforts to ensure your database connections are managed automatically when Action Cable is involved! Synchronized water ballet, anyone?
No Strings are better than NoSQL, right? Ankit noticed that the number_to_delimited and number_to_rounded helper methods were creating duplicate strings. Check out the pull request to see how he improved it using derailed_benchmarks to check object allocations 🍰
Rails has the need for speed 💨 and surfers Blake and Xavier managed a crowd-pleasing acceleration maneuver in AS::FileUpdateChecker using a single loop memoization rather than multiple loops, benchmarked using benchmark-ips. It's good stuff; see the PR for more! 🍦
Faster than relocating to San Francisco ✈️ (and much more fun), sun-drenched rider Lihan was able to speed up attribute_changed? by setting the default options parameter to nil instead of a hash, and checking the result with benchmark-ips 😎
Lifeguard Jeremy came across a common, hard-to-detect 🐞 in the water: Local message changes weren't being enqueued with the delivery job when using #deliver_later. This now raises a friendly exception to make sure your message modifications are made in either (a) the mailer method or (b) using a custom Active Job. Nice catch! 🌊
While surfing Mongoid's test suite, an error alerted our champion Emily 🏄🏾 to a change of behavior in ActiveSupport#symbolize_keys: Rails 4.1 returned a Hash but 4.2/5.0 returned self.class. This launched an interesting discussion on the merits of expected behavior versus matching Ruby's behavior. Have a look! 🍎
🌞 Wrapping Up 🌞
That's all for This Week on the Beach with Rails™ 🌴. There were many more improvements (and great waves) than we have room to cover here, so don't hesitate to jump in and check them out yourself... the water's warm and the locals are friendly! 👣🐾
