I agree. I just copied this line from models/article.php
https://github.com/joomla/joomla-cms/blob/staging/components/com_content/models/article.php#L55

At work it does not affect. Perhaps double parentheses were made for better code performance ?

Remove double parenthesis in line 61 or leave?

The $advClause param should probably be part of the key here as that will alter the query result, so what's cached can't really be re-used here.

@mbabker I thought about that. But that key can turn out too long

Current key

com_content|#__content|com_content.item|1

Key with $advClause

com_content|#__content|com_content.item|1|c2.access IN (1,1,5)|c2.language != 'en-GB'|(c2.publish_up = '0000-00-00 00:00:00' OR c2.publish_up <= '2018-04-25 11:39:07')|(c2.publish_down = '0000-00-00 00:00:00' OR c2.publish_down >= '2018-04-25 11:39:07')|c2.state = 1

Key with all arguments

com_content|#__content|com_content.item|1|id|alias|catid|c2.access IN (1,1,5)|c2.language != 'en-GB'|(c2.publish_up = '0000-00-00 00:00:00' OR c2.publish_up <= '2018-04-25 11:40:39')|(c2.publish_down = '0000-00-00 00:00:00' OR c2.publish_down >= '2018-04-25 11:40:39')|c2.state = 1

Choose, in this issue I do not have a principled position

The key with all the parameters is the most accurate if we talk about caching, but I'm not sure that such precision is needed

Personally I'm not concerned with key length, I'm more concerned with ensuring accuracy in the code. I do think having the id, alias, and catid column names in the key is redundant because it's not like the table schema is going to change in the middle of the request (and the table is already part of the key) so dropping those are a good idea.

Make this the key:

$queryKey = md5(serialize(array_merge(array($extension, $tablename, $context, $id), $advClause)));

The key length is now consistent and has enough entropy that if you run this method with two different $advClause parameters that your result won't be affected because that param isn't considered as part of the cache and inherently the second or later calls ignore it completely.
