Add sniff to detect usage of deprecated $wgUser
Closed, DeclinedPublic


Tim said we can phase out $wgUser in favor of RequestContext::getMain()->getUser()

We could use a PHP CodeSniffer sniff to report $wgUser should be replaced.

Don't we already have a deprecation system in general? (both for methods and for globals). How is phpcs relevant?

With the proper configuration, accessing deprecated methods or globals, a PHP error is emitted.

And what is the "proper" configuration to react whenever $wgUser is referenced / accessed ?

referenced / accessed ?

The proper solution is to assert that no php errors/notices are emitted during our running of the installer, php unit tests and http requests.

Marking as wontfix and suggest further discussion be at bug 48002.

Timo that is not covering everything. We want to get rid of $wgUser and the easiest is to detect whether it is used in the code, a sniff is a trivial thing to add in.

Attaching for posterity's sake.


Umherirrender notified on the change:

There is a DeprecatedGlobals.php to get deprecation warnings on a global (used for $wgArticle), but $wgUser is not deprecated at the moment, so this is only for a hint to the developer and should not be a blocking sniff.

So I guess that needs to be done directly in core instead of phpcs as Timo pointed out. Moving bugs under MediaWiki product.

Change 69090 abandoned by Hashar:
Implement DeprecatedGlobalSniff for $wgUser

I do not knew about DeprecatedGlobals.php seems it would get the job done. I have moved the bug report under MediaWiki product.

There is no patch pending. Reseting bug status.

What is this DeprecatedGlobals.php file?

The following patch is probably rather relevant.

I am interested in working on this. Should the PHP CodeSniffer sniff for $wgUser and warn to use RequestContext::getMain()->getUser() instead? Also, should it be automatically replaceable using phpcbf?

@Addshore, I think that @hashar's patch with changes to the description and a few other changes is what I had in mind. May I amend @hashar's patch, or submit a new one? I am relatively new here, and would love some guidance.

@Aashaka my patch on is the wrong approach. Reviewer hinted at DeprecatedGlobals.php.

We need the wgUser config for static functions as you can't do $this on static functions.

You can use RequestContext::getMain()->getUser() directly if it's a static function

Oh, thanks.

So, what's the status here? Adding wgUser is trivial, do we want to do it?

I guess that will be achieved by actually deprecating $wgUser: T159299
