Until now, Rails only droped compatibility with older
rubies on new majors, but I propose to change this policy
because it causes us to either keep compatibility with long
EOLed rubies or to bump the Rails major more often, and to
drop multiple Ruby versions at once when we bump the major.
In my opinion it's a bad alignments of incentives. And we'd
be much better to just drop support in new minors whenever they
go EOL (so 3 years).
Also Ruby being an upstream dependency, it's not even
a semver violation AFAICT.
Since Rails 7.2 isn't planned before a few months, we
can already drop Ruby 3.0 as it will be EOL in March.
Fix: https://github.com/rails/rails/issues/45017
Ref: https://github.com/rails/rails/pull/29333
Ref: https://github.com/ruby/timeout/pull/30
Historically only raised errors would trigger a rollback, but in Ruby `2.3`, the `timeout` library
started using `throw` to interupt execution which had the adverse effect of committing open transactions.
To solve this, in Active Record 6.1 the behavior was changed to instead rollback the transaction as it was safer
than to potentially commit an incomplete transaction.
Using `return`, `break` or `throw` inside a `transaction` block was essentially deprecated from Rails 6.1 onwards.
However with the release of `timeout 0.4.0`, `Timeout.timeout` now raises an error again, and Active Record is able
to return to its original, less surprising, behavior.
We had a discussion on the Core team and we don't want to expose this information
as a JSON endpoint and not by default.
It doesn't make sense to expose this JSON locally and this controller is only
accessible in dev, so the proposed access from a production app seems off.
This reverts commit 8eaffe7e89719ac62ff29c2e4208cfbeb1cd1c38, reversing
changes made to b6e4305c3bca4c673996d0af9db0f4cfbf50215e.
Generally followed the pattern for https://github.com/rails/rails/pull/32034
* Removes needless CI configs for 2.4
* Targets 2.5 in rubocop
* Updates existing CHANGELOG entries for fewer merge conflicts
* Removes Hash#slice extension as that's inlined on Ruby 2.5.
* Removes the need for send on define_method in MethodCallAssertions.
Without this change, bundler will resolve a gemfile which is pointing at
Rails master and not arel master. The error message that someone will
get from doing this will be incredibly unhelpful, as it'll be the result
of ActiveRecord being in a half-loaded that halted at `require
"arel/collectors/composite"`, which was subsequently rescued in
`"rails/all"`
