I ran into the issues described here when trying to install necessary
gems to contribute:

brianmario/mysql2#1350

Upgrading seems to have resolved the issue.

Closes #422. Thanks to @salmonsteak1 for spotting this.

Upgrade mysql2 gem

Co-authored-by: Rosa Gutierrez <rosa.ge@gmail.com>

Add helper method to query the latency on the Queue object

Closes #382 and #420.

* Adds to RVM .ruby-gemset to .gitignore for RVM and gemset holdouts.
* Updates Gemfile.lock to include arm64-darwin-24 (weird that it's
  missing)
* Adds 4 development dependencies to quiet deprecation warnings
* Updates rubocop to allow Ruby 3.3 syntax, matching .ruby-version

SolidQueue has excellent built-in error reporting. While this is
fantastic for SQ users, it is less than ideal for testing
SolidQueue because any test that deliberately uses or triggers an
exception produces voluminous error reporting.

This error reporting is hugely valuable when the exception is
not expected, but distracting and of limited value for expected
use-cases, especially when the test confirms the correct outcomes
via assertions.

This commit adds:
* A generic test-specific Exception class: ExpectedTestError
  This allows testing for specific exceptions while retaining
  all error reporting infrastructure for unexpected exceptions.

* Two helper methods for silencing on_thread_error output
  These methods accept an Exception or Array(Exception)
  and simply does not call the output mechanism if the
  exception passed to on_thread_error matches.
  This way, any unexpected error during test still
  reports in a highly visible manner while the exceptions
  being tested are validated via assertions.

* Replaces the stock on_thread_error with one that ignores
  ExpectedTextError.  Updated several tests from using
  the ruby stock RuntimeError to ExpectedTestError.

* Configures tests to run with YJIT enabled
  This is to test under likely production deployment configuration,
  not for performance reasons.

  Note: With the very recent reporting on M4's crashing on Mac's
  with YJIT enabled, we might want to either defer this change
  or add a conditional to opt in until the problem is resolved.

* Replaces a little Unix cleverness with a standard Ruby class.
  This pushes the responsibiity for meeting the SQ requirements
  from SQ to stock Ruby

* Delivers equivelent performance, identical API, and API behaviors
  with the original implementation (see note below on Futures)

* Mostly fixes a *platform / version dependent* issue with
  MySQL (see below)

* Meets 100% of SQ's functional requirements:

  * interruptible_sleep: a potentially blocking operation
    interruptible via either a "wake_event" (possibly requested
    prior to entering interruptible_sleep) or blocking until a
    timeout.

  * wake_up / interrupt: a Signal#trap and thread-safe method that
    does not require user-level synchronization (with the risk of
    not fully understanding all of the complexities required) code
    that either interrupts an inflight-interruptible_sleep or enqueues
    the event to processed in the invocation of interruptible_sleep

* Interruptible's API is trivially reproduceable via Thread::Queue
  * interruptible_sleep => Queue.pop(timeout:) where pushing anything
    into the queue acts as the interrupt event and timeout is reliable
    without any extra code or exception handling.

  * wake_up / interrupt => Queue.push(Anything) is thread, fiber, and
    Signal.trap safe (can be called from anywhere) and captures
    all wake_up events whenever requested, automaticall caching any
    "event" not processed by a currently executing interruptible_sleep
    matching existing functionality exactly.

Why the Future in #interruptible_sleep?

While Thread::Queue micro benchmarks as having the same performance on
the main thread Vs. any form of a sub-thread (or Fiber) and self-pipe,
when running the SQ test suite we see a 35% slow down Vs. the original
self-pipe implenentation.  One assumes this slowdown would manifest
in production. By moving the just the Queue#pop into a separate thread via
Concurrent::Promises.future we get +/- identical performance to the original
self-pipe implementation.

I'm assuming this root causes to Ruby main-thread only housekeeping and/or
possibly triggering a fast/slow path issue.

Why a Future Vs. Thread#new for each interruptible_sleep call?

Every other threaded operation in SQ is implemented using Concurrent
Ruby. Using a Future is for code and architectual consistency. There is
no difference in performance or functionality between the two.

MySQL *only* issues:

There seems to be a *platform specific* or *version specific* problem
with MySQL database connectivity and/or broken self-pipes leading to
randomly failing tests and a stream of distracting backtraces *even
with successful* tests.  Adding to the complexity sometimes, the lost
database connection can self-heal -- HOWEVER -- this takes time and given
how much of the test suite has time based assertions, leads to
additional random test failures.

These, or similar, issues have been observed in the past when changes to
the MySQL client library forced changes in the mysql2 gem.

With the Thread::Queue based implementation of the Interruptible concern,
the random failures and amount of spurious output are dramatically
improved (but not eliminated).

The previous version of this gem was struggling with reline.

Or, in other words, make the install generator idempotent.

Inspired by #349

* Streamlined a comment in the code
* Removed unneeded gemspec developer_dependencies that we get handled
  via the upgrade to Rails 7.1.4.1
* Added a gemspec version dependency required for keyword argument
  support
* Rebase to main

Reimplement Interruptible
