Before this patch , the CURLE_PEER_FAILED_VERIFICATION(60) error was returned when there was a certificate error, and resources could be obtained after the server trust evaluation process. However, because the CURLE_RECV_ERROR error was returned, this process was not performed, and resources could not be obtained. The reason why CURLE_PEER_FAILED_VERIFICATION was returned was because CURLOPT_HTTP_VERSION was set to CURL_HTTP_VERSION_3. Normally, the decision on whether to use HTTP/3 communication should be based on the alt-svc settings, but when CURL_HTTP_VERSION_3 is set, the initial communication will be performed in HTTP/3 regardless of the alt-svc settings. The curl uses ngtcp2 internally when performing HTTP/3 communication, but ngtcp2 functions continue to be used even after falling down to HTTP/2 communication. In this case, an error occurs in the ngtcp2 function during processing after detecting a certificate error, which causes the CURLE_RECV_ERROR error to be returned. To follow the Alt-Svc settings, set CURLOPT_HTTP_VERSION to CURL_HTTP_VERSION_NONE. This will allow curl to communicate with the appropriate HTTP version based on information from ALPN, alt-svc, etc. 2119203 6 kenji.shukuwa 2025-05-22 22:43:31 -0700 Pull request: https://github.com/WebKit/WebKit/pull/45817 2119206 7 kenji.shukuwa 2025-05-22 23:09:10 -0700 Don, could you please assign a reviewer? 2120030 8 ews-feeder 2025-05-27 19:09:53 -0700 Committed 295483@main (be42ad9a0ba6): <https://commits.webkit.org/295483@main> Reviewed commits have been landed.
