Welcome to Depfu 👋

This is one of the first three pull requests with dependency updates we've sent your way. We tried to start with a few easy patch-level updates. Hopefully your tests will pass and you can merge this pull request without too much risk. This should give you an idea how Depfu works in general.

After you merge your first pull request, we'll send you a few more. We'll never open more than seven PRs at the same time so you're not getting overwhelmed with updates.

Let us know if you have any questions. Thanks so much for giving Depfu a try!

Release Notes

6.1.3 (from changelog)

• Fix the MySQL adapter to always set the right collation and charset to the connection session.

  Rafael Mendonça França

• Fix MySQL adapter handling of time objects when prepared statements are enabled.

  Rafael Mendonça França

• Fix scoping in enum fields using conditions that would generate an IN clause.

  Ryuta Kamizono

• Skip optimised #exist? query when #include? is called on a relation with a having clause

  Relations that have aliased select values AND a having clause that references an aliased select value would generate an error when #include? was called, due to an optimisation that would generate call #exists? on the relation instead, which effectively alters the select values of the query (and thus removes the aliased select values), but leaves the having clause intact. Because the having clause is then referencing an aliased column that is no longer present in the simplified query, an ActiveRecord::InvalidStatement error was raised.

  An sample query affected by this problem:

  Author.select('COUNT(*) as total_posts', 'authors.*')
        .joins(:posts)
        .group(:id)
        .having('total_posts > 2')
        .include?(Author.first)

  This change adds an addition check to the condition that skips the simplified #exists? query, which simply checks for the presence of a having clause.

  Fixes #41417

  Michael Smart

• Increment postgres prepared statement counter before making a prepared statement, so if the statement is aborted without Rails knowledge (e.g., if app gets kill -9d during long-running query or due to Rack::Timeout), app won't end up in perpetual crash state for being inconsistent with Postgres.
