Note: I've split this change into two commits to allow for moving the second commit to the 3.0.0 release if so desired.


WPQueryParams: sniff for exclude array key being set

This:

  • Switches the WordPressVIPMinimum.Performance.WPQueryParams sniff over to use the WordPressCS AbstractArrayAssignmentRestrictionsSniff as the parent sniff.
  • Adds sniffing for the exclude array key via the AbstractArrayAssignmentRestrictionsSniff sniff logic.

Includes unit test.

Fixes #369

WPQueryParams: defer to the parent sniff

This changes over the existing keys being sniffed for by this sniff to use the logic from the new AbstractArrayAssignmentRestrictionsSniff parent instead of custom logic.

Note: this is a BC-break as the error codes for the existing checks change!

  • WordPressVIPMinimum.Performance.WPQueryParams.PostNotIn is now WordPressVIPMinimum.Performance.WPQueryParams.PostNotIn_post__not_in
  • WordPressVIPMinimum.Performance.WPQueryParams.SuppressFiltersTrue is now WordPressVIPMinimum.Performance.WPQueryParams.SuppressFilters_suppress_filters

Since post__not_in and exclude are the same, should we punt it into one group?

I considered that, but we'd need to have a careful think about the warning message in that case as using the existing message would be confusing (which is why they are in separate groups now).

We can definitely revamp the warning message to something more ambiguous.

I'll have a think about it. Suggestions welcome.

Maybe something like...
"Using exclusionary parameters should be done with caution, see https://wpvip.com/documentation/performance-improvements-by-removing-usage-of-post__not_in/ for more information."

We can even re-vamp the documentation a bit to account for it as well.

As noted in #369, I'd prefer the second commit to be punted to 3.0 - thanks for thinking ahead and splitting out the code into the two commits!

This:
* Switches the `WordPressVIPMinimum.Performance.WPQueryParams` sniff over to use the WordPressCS `AbstractArrayAssignmentRestrictionsSniff` as the parent sniff.
* Adds sniffing for the `exclude` array key via the `AbstractArrayAssignmentRestrictionsSniff` sniff logic.

Includes unit test.

@GaryJones I've removed the second commit from the PR (kept locally with a "wait/3.0" annotation).

@rebeccahum I've changed the group key for exclude to PostNotIn so those two keys can be joined in one group with one message when we address part 2 of this issue.

Once this PR is merged, a new issue should be opened for 3.0 as a reminder that the rest of the sniff still needs to be switched over to the new abstract.
