Sorry, something went wrong.
Previously if an array of raw headers was provided to writeHead, and that array contained any duplicate keys, only the last value was recorded for that key and all others were lost. This changes bring the HTTP/2 compat logic in line with the logic for HTTP/1, so that writeHead headers overwrite any previous conflicting setHeader headers, but do not overwrite themselves.

CI failures all seem to have github actions setup errors where they fail to initialize entirely, unrelated to these changes. Looks like there was a brief GH outage as this ran that's now been resolved, should hopefully work if somebody can rerun them please. |

Looks like this is all passing & mergeable now @debadree25, so I'll skip the rebase for the moment. Thanks for rerunning those tests! Just waiting for somebody familiar with the HTTP/HTTP2 code to review now 😄 |

In both cases, the specific code is drawn almost directly from the existing HTTP/1 equivalent (I've mildly tweaked the phrasing in the H1 appendHeader docs en route, as the grammar was a bit off).
There will be some performance impact to this for some uses of the H2 compat API, but I think this should be relevant only in the case where you call setHeader on a response and then also pass a separate list of headers to writeHead for that response. Performance-sensitive code should not do this, and should just pass all headers directly to writeHead in one go instead. The same concerns already apply to HTTP/1.
