This reverts commit 4e05bfb8e254c3360a3ca4a6cb332995314338fe.
Reason: BlankTopic#blank? should not be removed to check that dynamic finder with a bang can find a model that responds to `blank?`
The native JSON library bypasses the `to_json` overrides in
active_support/core_ext/object/to_json.rb by calling its native
implementation directly. However `ActiveRecord::Store` uses a
HWIA so `JSON.dump` will call our `to_json` instead with a
`State` object for options rather than a `Hash`. This generates
a warning when the `:encoding`, `:only` & `:except` keys are
accessed in `Hash#as_json` because the `State` object delegates
unknown keys to `instance_variable_get` in its `:[]` method.
Workaround this warning in the test by using a custom coder that
calls `ActiveSupport::JSON.encode` directly.
If we set encoding latin1 for a PostgreSQL database, it calls
PostgreSQLAdapter::create_database with options that have,
among other things:
{ 'encoding' => 'latin1' }
Then, we use reverse_merge(:encoding => "utf8") to setup the default
encoding. In the end, the hash looks like:
{ :encoding => 'utf8', 'encoding' => 'latin1' }
The call to options.symbolize_keys calls to_sym on each_key of this
Hash. It usually means that the encoding passed overwrites the default
utf8, but it's not guaranteed. So, we shouldn't rely on it.
The same was happening in ActiveRecord::ConnectionHandling.
This reverts commit 1fc294f988e93ac59057a16b0e44b9cf93af9720, reversing
changes made to fb9ac47c286fbdfe05263d4d0346e50892090603.
Reason: these tests should run fine independent of database, since they
should only take into account the configuration options. The problem was
related to a change in the way "nil" is handled by the rescue clause, in
Ruby 2.0 it raises an exception asking for class or module, in 1.9 it
passes.
When running tasks such "rake db:setup", instead of showing messages
like "db_development already exists", it was showing a big stack trace
and a message "Couldn't create database for ..." with the configuration
options, a very confusing message with a big trace.
This brings back the functionality present in 3-2, showing the same
message.
in a default_scope.
`Model.joins(...).where(condition_on_joined_table).update_all` /
`delete_all` worked, but the same operation implemented with a
default_scope generated a SQL error because ActiveRecord ignored the
join but implemented the where condition anyways.
