whether to exec with cache for Postgresql adapter
Reduces creating unused objects, with the most dramatic reduction in select_values which used to map(&:first) an array of single element arrays.

This was a common pattern:
```
query = author.posts.select(:title)
connection.select_one(query)
```
However `.select` returns a ActiveRecord::AssociationRelation, which has
the bind information, so we can use that to get the right sql query.
Also fix select_rows on postgress and sqlite3 that were not using the binds

This is to be consistent with the way the mysql2 adapter times queries
|
| | |
|
| | |
|
| | |
|
| |
|
|
|
|
|
|
|
| |
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
disabled.
Fixes #12023

This reverts commit 521035af530482d6d9ad2dae568eaeb0ab188e1c, reversing
changes made to 222011dbee842bbc60d3aaaa3145356b90a30fd1.
Reason: This broke the tests

* dependencies/autoload
* concern
* deprecation
|
| | |
|
| |
|
|
| |
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.

If your database supports setting the isolation level for a transaction,
you can set it like so:
Post.transaction(isolation: :serializable) do
# ...
end
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:
* http://www.postgresql.org/docs/9.1/static/transaction-iso.html
* https://dev.mysql.com/doc/refman/5.0/en/set-transaction.html
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
(http://bugs.mysql.com/bug.php?id=39170) which means the isolation level
gets persisted outside the transaction.

This method was first seen in 045713ee240fff815edb5962b25d668512649478,
and subsequently reimplemented in
fb2325e35855d62abd2c76ce03feaa3ca7992e4f.
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
only.
