    Check if the SQL is not a prepared statement

    rafaelfranca committed
    When the adapter is with prepared statement disabled and the binds array
    is not empty the connection adapter will try to set the binds values and
    will fail. Now we are checking if the adapter has the prepared statement
    Fixes #12023

    Provide a call stack for deprecation warnings where needed.

    nikitug committed
    It's sometimes hard to quickly find where deprecated call was performed, especially in case of migrating between Rails versions. So this is an attempt to improve the call stack part of the warning message by providing caller explicitly.

    Support for specifying transaction isolation level

    jonleighton committed
    If your database supports setting the isolation level for a transaction,
    you can set it like so:
      Post.transaction(isolation: :serializable) do
        # ...
    Valid isolation levels are:
    * `:read_uncommitted`
    * `:read_committed`
    * `:repeatable_read`
    * `:serializable`
    You should consult the documentation for your database to understand the
    semantics of these different levels:
    An `ActiveRecord::TransactionIsolationError` will be raised if:
    * The adapter does not support setting the isolation level
    * You are joining an existing open transaction
    * You are creating a nested (savepoint) transaction
    The mysql, mysql2 and postgresql adapters support setting the
    transaction isolation level. However, support is disabled for mysql
    versions below 5, because they are affected by a bug
    ( which means the isolation level
    gets persisted outside the transaction.

    Remove our use of #outside_transaction?

    jonleighton committed
    This method was first seen in 045713e,
    and subsequently reimplemented in
    According to @jeremy, this is okay to remove. He thinks it was added
    because at the time we didn't have much transaction state to keep track
    of, and he viewed it as a hack for us to track it internally, thinking
    it was better to ask the connection for the transaction state.
    Over the years we have added more and more state to track, a lot of
    which is impossible to ask the connection for. So it seems that this is
    just a relic of the passed and we will just track the state internally
