Thank you @nicolas-grekas. |

Thanks @nicolas-grekas - hopefully that does solve this very sneaky issue. Sounds to me like it'd be worth a bug report to curl too though, if you have enough details to send them. |

With this change, I don't reproduce the failures that I describe in composer/composer#9481 when running the script in #38690
Apparently curl has an issue when both h1.1 and h2 connections are open to the same host.
Instead of switching to HTTP/1.1 when retrying requests that failed because of an HTTP/2 stream error, I propose to close the http/2 connection when issuing a retry.
With this change, running the mirroring script of packagist works like a charm.
No need to investigate your mirrors @Seldaek, this was definitely a data corruption issue.
