The select_all method always returns ActiveRecord::Result instance,
and the ActiveRecord::Result includes Enumerable mixin.
If #empty?, #first method returns nil. Thus we can simplify this method.
content tag already knows which tags are boolean and the values that
should generate them when a truthy value is passed, so leave this logic
for it instead of duplicating when generating options tags.
Showing welcome page in production can expose information, which should
not be visible on production if people don't override the default root
route.
This reverts commit b0caea29c2da9f4c8bb958019813482da297067d.
Previously, the cache size of `ActiveSupport::Cache::MemoryStore` was calculated
as the sum of the size of its entries, ignoring the size of keys and any data
structure overhead. This could lead to the calculated cache size sometimes being
10-100x smaller than the memory used, e.g., in the case of small values.
The size of a key/entry pair is now calculated via `#cached_size`:
def cached_size(key, entry)
key.to_s.bytesize + entry.size + PER_ENTRY_OVERHEAD
end
The value of `PER_ENTRY_OVERHEAD` is 240 bytes based on an [empirical
estimation](https://gist.github.com/ssimeonov/6047200) for 64-bit MRI on
1.9.3 and 2.0.
Fixes GH#11512 https://github.com/rails/rails/issues/11512
Some adapters require column information to do their job properly.
By enforcing the provision of the column for this internal method
we ensure that those using adapters that require column information
will always get the proper behavior.
This includes fixing typos in changelog, removing a deprecated
mocha/setup test require, and preferring the `column_for_attribute`
accessor over direct access to the columns_hash in the new code.
When calling quote_value the underlying connection sometimes requires
more information about the column to properly return the correct quoted
value.
I ran into this issue when using optimistic locking in JRuby and the
activerecord-jdbcmssql-adapter. In SQLSever 2000, we aren't allowed to
insert a integer into a NVARCHAR column type so we need to format it as
N'3' if we want to insert into the NVARCHAR type. Unfortuantely, without
the column type being passed the connection adapter cannot properly return
the correct quote value because it doesn't know to return N'3' or '3'.
This patch is fairly straight forward where it just passes in the column
type into the quote_value, as it already has the ability to take in the column,
so it can properly handle at the connection level.
I've added the tests required to make sure that the quote_value method
is being passed the column type so that the underlying connection can
determine how to quote the value.
Fixes#11497
As `ActiveRecord::ConnectionAdapters::ConnectionManagement` middleware does not rescue from Exception (but only from StandardError),
the Connection Pool quickly runs out of connections when multiple erroneous Requests come in right after each other.
Recueing from all exceptions and not just StandardError, fixes this behaviour.
