RAILS PATCHES NUMBER FORMATTING AND COMPARISON BUGS OVERNIGHT

By RepoJournal · Filed · About Rails · Composed from the cited sources · methodology

Three critical fixes landed in Rails core to stop InheritableOptions from crashing on equality checks and number_to_delimited from corrupting signed integers.

Rails merged a fix [1] for InheritableOptions#== that was violating Ruby's equality contract by raising NoMethodError when compared to non-Hash objects like strings or integers. That same violation was surfacing through implicit equality checks everywhere the class appeared, turning what should be a boolean into a crash. The team also landed a fix [2] for number_to_delimited corrupting numbers with leading signs, a formatter bug that would have broken any code stringifying currency or percentages with negative values. A third merge [3] corrected a URL fragment in the Active Record Migrations guide. These are the kind of silent failures that ship to production unnoticed until they don't: your test suite passes, your app boots, then a customer hits the right code path and everything stops. The migrations guide fix [4] is documentation only, but the other two are live bugs in widely-used Rails utilities.
