Reason for revert: Test failures: https://chromegw.corp.google.com/i/client.v8/builders/V8%20Linux64/builds/3829 Original issue's description: > Promise assimilation fix. > > Let x be a fulfilled promise and y be another promise. |x.then(() => y)| > should call |y.then|, but the current implementation calls PromiseChain. > We can see the difference when we set a custom function to |y.then|. > > This CL fixes the spec violation, but as a result |then| is no longer > a wrapper of |chain| and in some cases it does not work well with > |accept| or |chain|. That is not a problem for ES6 promise users because > ES6 promise doesn't have them. > > LOG=N > BUG=477921 > > Committed: https://crrev.com/2f57dff3ea0c45e1a61b334fda962460f89d71bc > Cr-Commit-Position: refs/heads/master@{#28926} TBR=arv@chromium.org,caitpotter88@gmail.com,rossberg@chromium.org,yhirano@chromium.org NOPRESUBMIT=true NOTREECHECKS=true NOTRY=true BUG=477921 Review URL: https://codereview.chromium.org/1176163004 Cr-Commit-Position: refs/heads/master@{#28927} |
