Assistance Disclosure
AI was used. I used Claude Code to help draft PR message and understand the codebase. I worked as a peer-programmer.
What this does
In
HTTPTransport's customdialContextclosure (modules/caddyhttp/reverseproxy/httptransport.go), the connection is established viadialer.DialContextand then, whenproxy_protocolis configured, several error paths returned without closing the already-open connection, leaking the socket:This closes
connon each of those paths. The dial-failure return (where no connection exists yet) and the success path are unchanged.Addresses the reverse proxy item in #7833. Per the maintainer's suggestion in that issue, the other reported leaks are left for separate PRs by area.
Testing
go build ./...go test -race ./modules/caddyhttp/reverseproxy/passes
