DevMode: Allow the API to return a preferred server#325
Conversation
|
""" WalkthroughThe Server struct now includes a separate hostname field, which is set from the connection response if available. The ConnectionResponse struct's data also supports an optional Hostname field in its JSON output. Connection logic was updated to use this hostname for TLS connections, and a minor syntax correction was made. Changes

252-252: Consider updating this log message to use hostnameFor consistency with the warning message on line 232, consider updating this success log to also use the hostname variable instead of serverAddr.
-s.logger.Debug("connection established to %s", s.serverAddr) +s.logger.Debug("connection established to %s", hostname)
74-74: Consider adding documentation for the hostname fieldTo help future developers understand the purpose of this field and its relationship to serverAddr, consider adding a comment explaining that the hostname is used for TLS connections and can be dynamically provided by the API.
+ // hostname is the server hostname used for TLS connections, can be dynamically set from API response hostname string

74-74: LGTM: Added hostname field to Server structAdding this field allows the server to maintain a separate hostname from the server address, which is necessary for supporting the API's ability to return a preferred server.
102-102: LGTM: Added Hostname field to ConnectionResponse.DataThe field is correctly added with the
omitemptyJSON tag, making it backward compatible with existing responses that don't include this field.
150-150: LGTM: Storing the hostname from connection responseThe code now correctly captures the hostname from the connection response, if provided.
216-219: LGTM: Added fallback mechanism for hostnameGood implementation of the fallback logic - if the API doesn't provide a hostname, the system will continue to use the serverAddr as before.
221-227: LGTM: Updated localhost and port checks to use hostnameCorrectly updated the checks that were previously applied to serverAddr to now use the hostname variable.
229-233: LGTM: Using hostname for TLS connectionThe code now correctly uses the hostname for both the TLS dial operation and in the warning log message, ensuring consistent behavior.
439-439: LGTM: Removed semicolon from traceState.InsertMinor syntax fix that improves code consistency.
216-219: Verify fallback behavior with automated testsEnsure you have test coverage for both scenarios - when the API provides a hostname and when it doesn't (falling back to serverAddr).
You might want to create unit tests that verify:
- When ConnectionResponse includes a Hostname, it's used for the TLS connection
- When ConnectionResponse doesn't include a Hostname, the serverAddr is used instead
