Description Aakash Jain 2021-08-19 10:14:41 PDT

Noticing this intermittent build failure on windows in InspectorCSSAgent.cpp 'Backdrop': undeclared identifier.

WebCore\inspector/agents/InspectorCSSAgent.cpp(453,41): error C2838: 'Backdrop': illegal qualified name in member declaration
WebCore\inspector/agents/InspectorCSSAgent.cpp(453,49): error C2065: 'Backdrop': undeclared identifier

This is causing false positives on windows-ews.

e.g.:
https://ews-build.webkit.org/#/builders/10/builds/101698
https://ews-build.webkit.org/#/builders/10/builds/101870
https://ews-build.webkit.org/#/builders/10/builds/101867
https://ews-build.webkit.org/#/builders/10/builds/101855
https://build.webkit.org/#/builders/56/builds/4022

Presumably this is related to https://trac.webkit.org/changeset/281229/webkit?

Comment 2 Ryan Haddad 2021-08-19 15:15:57 PDT

There hasn't been a build failure on trunk bots since the one linked above, so maybe this had something to do with incremental builds?
