"""Replace hardcoded `localhost` URLs in the imported XVI checkers with self.url().
|
||
|
|
|
||
|
|
Why: the imported checkers connect to `http://localhost:{self.port}`. The
|
||
|
|
receiver does run on the same host as the published team ports, so this happens
|
||
|
|
to work, but it is fragile (breaks the moment a receiver runs in a container or
|
||
|
|
the port is bound to a specific interface). Challenge.url() builds the URL from
|
||
|
|
self.host (default 127.0.0.1, overridable with RECEIVER_HOST) plus self.port.
|
||
|
|
|
||
|
|
Idempotent; rewrites only the f-string form, leaving class-level constants that
|
||
|
|
pin a *fixed* port (GemasNotes/Pasta/S3) alone — those are handled separately.
