CI build failing for some ext repos due to PhanUndeclaredClassMethod "undeclared class \Block"
Closed, ResolvedPublic⚠
Actions

Description

For all PageTriage commits, and possibly other extensions as well. Currently blocking ability to merge masters in those master branches.

<file name="includes/Hooks.php">
  <error line="518" severity="warning" message="Parameter $block has undeclared type \Block" source="PhanUndeclaredTypeParameter"/>
</file>
<file name="includes/PageTriageUtil.php">
  <error line="361" severity="warning" message="Parameter $block has undeclared type \Block" source="PhanUndeclaredTypeParameter"/>
  <error line="376" severity="error" message="Call to method getTarget from undeclared class \Block" source="PhanUndeclaredClassMethod"/>

It seems for some reason Phan isn't understanding the class alias for Block.

Wikimedia production calls to fix: https://codesearch.wmflabs.org/deployed/?q=(new%20Block%5C(%7C%5CbBlock%3A%3ATYPE_%7C%40(param%7Cvar%7Creturn)%20Block%5Cb)&i=nope&files=&repos=

The Block class is only defined as an alias:

class_alias( DatabaseBlock::class, 'Block' );

My guess is that because Phan is a static analyser it can't guarantee it will be able to read the second argument as a class name, so it doesn't try. I'm guessing updating Block to DatabaseBlock (or AbstractBlock) in the affected extensions will fix this.

We can update the affected extensions.

Is this the first class alias Phan has had to deal with?

Apparently we can use enable_class_alias_support in Phan config somehow, but there are only thirteen prod repos creating a Block class, so…

Thanks @Jdforrester-WMF and @Umherirrender. The extensions that document @param Block, @var Block and @return Block should now have patches updating all their references to Block, tagged with this task.

We'll update the extensions that aren't causing Phan to fail too, but won't tag them here.

We've been doing this for the Wikimedia\Rdbms classes for a while which Phan seems to be fine with. (e.g. ResultWrapper, IDatabase and Database, are global aliases.) I took a quick look at how those are set up and it seems identical to the way you've done it for Block, so I'm not sure why Phan complained about these but not the others.

It's possible that something has regressed in newer Phan versions and/or our configuration of it, and that it might now be broken for IDatabase as well. However, we're not likely to find out about that because we've since fixed it in most of the active repos. It's possible that the older repos still using IDatabase are also broken, in which case we'd find out next time someone proposes a commit for those repos.
