Don't translate non-database exceptions.
|
| | |/ / /
| | | |
| | | |
| | | | |
The AbstractAdapter will translate all StandardErrors generated during the course of a query into ActiveRecord::StatementInvalids. Unfortunately, it'll also mangle non-database-related errors generated in ActiveSupport::Notification callbacks after the query has successfully completed. This should prevent it from translating errors from ActiveSupport::Notifications.

Improve the performance of writing attributes
|
| | | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | |
| | | | | |
This name more accurately describes what the method does, and also
disambiguates it from `_write_attribute`, which ignores aliases.
We can also make the method private, since it's not public API and only
called from one place - `update_columns` - without an explicit receiver.

Using a similar approach to 08576b94ad4f19dfc368619d7751e211d23dcad8,
this change adds a new internal `_write_attribute` method which bypasses
the code that checks for attribute aliases and custom primary keys.
We can use this method instead of `write_attribute` when we know that we
have the name of the actual column to be updated and not an alias.
This makes writing an attribute with `attribute=` about 18% faster.
Benchmark:
```

require "bundler/inline"
rescue LoadError => e
$stderr.puts "Bundler version 1.10 or later is required. Please update your Bundler"
raise e

end
end

end
post = Post.new(id: 1)
Benchmark.ips do |x|
x.report("attribute=") { post.id = post.id + 1 }
end

Let's say you have a nested transaction and both records are saved.
Before the outer transaction closes, a rollback is performed. Previously
the record in the outer transaction would get marked as not persisted
but the inner transaction would get persisted.
```ruby
Post.transaction do
post_one.save # will get rolled back
Post.transaction(requires_new: true) do
post_two.save # incorrectly remains marked as persisted
end
raise ActiveRecord::Rollback
end
```
To fix this the PR changes transaction handling to have the child
transaction ask the parent how the records should be marked. When
there are child transactions, it will always be a SavpointTransaction
because the stack isn't empty. From there we pass the parent_transaction
to the child SavepointTransaction where we add the children to the parent
so the parent can mark the inner transaction as rolledback and thus mark
the record as not persisted.
`update_attributes_from_transaction_state` uses the `completed?` check to
correctly mark all the transactions as rolledback and the inner record as
not persisted.
```ruby
Post.transaction do
post_one.save # will get rolled back
Post.transaction(requires_new: true) do
post_two.save # with new behavior, correctly marked as not persisted
on rollback
end
raise ActiveRecord::Rollback
end
```

`set_state` was directly setting the transaction state instance
variable. It's better to set the state via specific methods (`rollback!`
and `commit!` respectively.
While undocumented and untested, it's possible someone is using
`set_state` in their app or gem so I've added a deprecation notice to
it.
No where in the app do we use `nullify!` but I wanted to keep existing
behavior while replacing the method with a better pattern.

Active Record doesn't rely delegating to `arel` in the internal since
425f2ca. The delegation is a lower priority than delegating to `klass`,
so it is pretty unclear which method is delegated to `arel`.
For example, `bind_values` method was removed at b06f64c (a series of
changes https://github.com/rails/rails/compare/79f71d3...b06f64c). But a
relation still could respond to the method because `arel` also have the
same named method (#28976).
Removing the delegation will achieve predictable behavior.
