requestStorageAccess not yet working #7

Closed hilnius closed 11 months ago

hilnius commented 1 year ago

Hello If i understand correctly : When site a.com includes an iframe on b.com, if I control both sites, and wish to share b.com's data (the iframe) with a.com (the parent window), I should call requestStorageAccess from my b.com page and then use postMessage to transfer data to a.com. Is that correct ?

If it is, then at the moment, it's pretty hard to test that "Experimental third-party storage partitioning." flag in Chrome. Indeed, in order to share data through an iframe (and some postMessages checking the correct origins), with that new flag on, there needs to be a way for the child iframe to actually access the storage of b.com (a correct workaround). and currently requestStorageAccess doesn't work as expected - so I can't really keep this flag enabled.

So just saying : I don't think that this feature can be rolled out without a correct workaround for this use case - using the requestStorageAccess would be the favorite candidate from what I can understand - but it's still not ready so it's hard to test this feature yet.

Apologies to miss this issue. We're prototyping a mode for requestStorageAccess to request a handle to unpartitioned storage. There should be an origin trial you can test soon: https://groups.google.com/a/chromium.org/g/blink-dev/c/SEL7N-xIE5s/m/8puhB8T1BgAJ
