@xyaoinum, could you PTAL? Had a question about how best to write this (see comment). Thanks!
Also note that the spec build is failing due to some missing exports, but I have a different PR to fix that in the PAA repo that I'll land first.

Wasn't sure how to evaluate this properly (in spec language) unless we decide that returning a non-integer should count as an uncaught exception for aggregate error reporting

A non-integer will often be implicitly converted to an integer without error, see test case SelectURL_NonNumericStringConvertedTo0. AFAICT, the only possible integer conversion failure is to return an object that defines a custom toString() method that throws, e.g. SelectURL_ReturnValueToUint32Error. I think it's fine to simply assume 'uncaught exception' here.

Ah interesting -- I've updated this PR to reflect that / remove the unnecessary if clause. I'll try to add a test case for this situation in the implementation too. Thanks!

Adds support for the new Private Aggregation error reporting feature to Shared Storage. See the related PAA spec change: patcg-individual-drafts/private-aggregation-api#172 Also see the explainer: https://github.com/patcg-individual-drafts/private-aggregation-api/blob/main/error_reporting.md Slightly reorganizes the PAA integration with this spec for readability.

Thanks for the review! Fixed the build and updated the 'uncaught exception' test. |
Adds support for the new feature and its contributeToHistogramOnEvent() method. Requires plumbing the cause of a Shared Storage operation completing to the PrivateAggregation object to support contributions conditional on an uncaught exception.
