Hi!
In AssetMapper, we throw a
CircularAssetsExceptionif you ask for theapp.jsasset, but it's still being created. This circular situation only happens via asset compilers: if, while compilingapp.js, we ask forother.js... and then while compiling that, we ask forapp.js.However, JS modules do allow for circular references - e.g.
app.jsimportsother.jswhich importsapp.js. Before this PR, this situation would trigger theCircularAssetsException. After, it is handled correctly.JavaScriptImportPathCompilercalls$assetMapper->getAsset()only to populate theMappedAsset.javaScriptImportsproperty. So, allowing for the half-createdMappedAssetis safe here: we do not use any of the not-yet-populated properties.Cheers!
