Update activerecord requirement from ~> 6.0 to ~> 7.0

[dependabot]

Updates the requirements on activerecord to permit the latest version.

Release notes

Sourced from activerecord's releases.

7.0.0

Action Cable

• The Action Cable client now ensures successful channel subscriptions:

  • The client maintains a set of pending subscriptions until either the server confirms the subscription or the channel is torn down.
  • Rectifies the race condition where an unsubscribe is rapidly followed by a subscribe (on the same channel identifier) and the requests are handled out of order by the ActionCable server, thereby ignoring the subscribe command.

  Daniel Spinosa

• Compile ESM package that can be used directly in the browser as actioncable.esm.js.

  DHH

• Move action_cable.js to actioncable.js to match naming convention used for other Rails frameworks, and use JS console to communicate the deprecation.

  DHH

• Stop transpiling the UMD package generated as actioncable.js and drop the IE11 testing that relied on that.

  DHH

• Truncate broadcast logging messages.

  J Smith

• OpenSSL constants are now used for Digest computations.

  Dirkjan Bussink

• The Action Cable client now includes safeguards to prevent a "thundering herd" of client reconnects after server connectivity loss:

  • The client will wait a random amount between 1x and 3x of the stale threshold after the server's last ping before making the first reconnection attempt.
  • Subsequent reconnection attempts now use exponential backoff instead of logarithmic backoff. To allow the delay between reconnection attempts to increase slowly at first, the default exponentiation base is < 2.
  • Random jitter is applied to each delay between reconnection attempts.

  Jonathan Hefner

Action Mailbox

• Removed deprecated environment variable MAILGUN_INGRESS_API_KEY.

Changelog

Sourced from activerecord's changelog.

Rails 7.0.0 (December 15, 2021)

• Better handle SQL queries with invalid encoding.

  Post.create(name: "broken \xC8 UTF-8")

  Would cause all adapters to fail in a non controlled way in the code responsible to detect write queries.

  The query is now properly passed to the database connection, which might or might not be able to handle it, but will either succeed or failed in a more correct way.

  Jean Boussier

• Move database and shard selection config options to a generator.

  Rather than generating the config options in production.rb when applications are created, applications can now run a generator to create an initializer and uncomment / update options as needed. All multi-db configuration can be implemented in this initializer.
