Thanks for bringing this up, Anssi. The diff between the REC and the latest Editor’s Draft[1] indicated at least two normative changes, so I’d like to propose a second edition of Web Storage. What do you say?
Here’s my analysis for the current mutex. All your comments are welcome. * ED L174, L283 - WEBIDL Updated. The getter of the Storage interface and the key of the StorageEvent are Nullable; - The test suite has been update for these changes[2][3] . These changes are widely implemented by the browsers. - These changes are normative and should be accepted in the second edition. * ED L187 - The supported property names on a Storage object should be "in the order that the keys were last added to the storage area”(added). - I wrote a test case[4] for this but the implementation doesn’t seem to follow this instruction. It’s more likely to be *in the order of keys that was defined by the user-agent*. - Giving the fact this change is non-normative, we should either ignore it or update the instruction to be *in the order of keys that was defined by the user-agent*. * ED L262 - Remove 4.3.1 (LocalStorage) Security. - The former section claimed that user agents must throw a SecurityError whenever any of the members of a Storage object originally returned by the localStorage attribute are accessed by scripts whose effective script origin is not the same as the origin of the Document of the Window object on which the localStorage attribute was accessed. - There was discussion[5] that this section wasn’t clear enough, dating back to 2012. I couldn’t find any related topics in the mailing list about why the editor removed this section after the Rec. - My test case[6] indicates none of Chrome/Firefox/Safari throws the SecurityError in that case. - This is a normative change and should be accepted in the second edition. Other changes are more editorial and can be kept in the second edition, imo. Moreover, the archives of the Issue section need to be updated in the new document because the formal archives are no longer available. A draft second edition of WebStorage[7](diff[8]) is available in GitHub. Please feel free to raise issues or PRs there. FYI, according to the 2014 process document[9], to modify a Rec, we can either go through FPWD->CR->PR->REC, or if we can prove wide review for the changes, things will be easier, i.e., CR->PR->REC.
