soap: do not overwrite the parsed host on a protocol-relative redirect#22431
Merged
Conversation
When a redirect Location is a protocol-relative reference (//host/path), the URI parser already fills new_uri->host, but the scheme-less redirect handling overwrote it with a copy of the request host without releasing the parsed one. That leaks a zend_string per such redirect and pins the redirect back to the original host instead of the one the server named. Inherit host and port from the request URI only when new_uri->host is NULL, mirroring the scheme guard directly above.

When a redirect Location is a protocol-relative reference (//host/path), the URI parser already fills new_uri->host, but the scheme-less redirect handling overwrote it with a copy of the request host without releasing the parsed one. That leaks a zend_string per such redirect (valgrind: 40 bytes definitely lost, traced to the Location parse) and pins the redirect back to the original host instead of the one the server named. Inherit host and port from the request URI only when new_uri->host is NULL, mirroring the scheme guard directly above. Follow-up to the scheme-less redirect handling added in #22341.
