| * Action Cable owns database connection, not Active RecordJon Moss2017-03-251-8/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, the database connection used in Action Cable's PostgreSQL adapter was "owned" by `ActiveRecord::Base.connection_pool`. This meant that if, for example, `#clear_reloadable_connections!` was called on the pool, Active Record would "steal" the database connection from Action Cable, and would cause all sorts of issues. This became evident during file reloads; despite Action Cable trying its hardest to return its borrowed database connection to Active Record via `@pubsub.shutdown`, Active Record calls `#clear_reloadable_connections!` on the connection pool, and due to the order of callbacks, Active Record's callback was being executed first. This meant that if you tried to rerender a view after a file was reloaded, you would have to wait through Active Record's timeout and such. Now, Action Cable takes direct ownership of the database connection it uses. It removes the connection from the pool to avoid the situation described above. Action Cable also makes sure to call `#disconnect!` on the connection when appropriate, to match the previous behavior of Active Record. [ Jon Moss & Matthew Draper]
* | PostgreSQL: Allow pg-1.0 gem to be used with ActiveRecordLars Kanis2018-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | pg-1.0.0 is just released and most Gemfiles don't restrict it's version. But the version is checked when connecting to the database, which leads to the following error: Gem::LoadError: can't activate pg (~> 0.18), already activated pg-1.0.0 See also this pg issue: https://bitbucket.org/ged/ruby-pg/issues/270/pg-100-x64-mingw32-rails-server-not-start Preparation for pg-1.0 was done in commit f28a331023fab, but the pg version constraint was not yet relaxed.

| | | | | | | | | | | | | | Inserted spaces in the name of Rails components. Since I was on it, also used PostgreSQL instead of Postgres because albeit Postgres is an accepted alias, PostgreSQL is the official name and the actual name of the adapter. See https://wiki.postgresql.org/wiki/ProjectName with regard to PostgreSQL vs Postgres.
