Description Michael Catanzaro 2015-07-20 17:16:49 PDT

I don't understand Perl nor what is going on here, but it looks bad:

Nothing has changed here recently, so I have no clue why I am only now seeing the warnings.

I could only find two changes to IDLParser.pm near July 2015:

https://github.com/WebKit/WebKit/commit/05fa8411002fefbd0a66859046f0ac4a78e3bb2f

https://github.com/WebKit/WebKit/commit/1d068a4b1cc7149de5fc6fc443950fb085d004ed

First one seems to be more about fixing these type of warnings. Just wanted to share what I could fine and I could be completely but just wanted to update. Thanks!

Comment 2 Alexey Proskuryakov 2022-08-19 16:49:27 PDT

Yes, 167542@main was the fix.
