1-92: Consider enhancing error handling and message construction.The function could benefit from some structural improvements:
- Error handling could be more specific using custom error types instead of generic
Error::msg- Message construction for buyer and seller is duplicated and could be extracted into a helper function
- Status updates and notifications could be wrapped in a transaction to ensure consistency
Consider refactoring like this:
// Add at the top with other uses use anyhow::Context; // Helper function for sending notifications async fn notify_parties( order_id: i64, buyer: &PublicKey, seller: &PublicKey, request_id: Option<String>, ) { let buyer_peer = Peer::new(seller.to_string()); let seller_peer = Peer::new(buyer.to_string()); // Notify seller (no request_id needed) send_new_order_msg( None, Some(order_id), Action::FiatSentOk, Some(Content::Peer(seller_peer)), seller, ).await; // Notify buyer with request_id send_new_order_msg( request_id, Some(order_id), Action::FiatSentOk, Some(Content::Peer(buyer_peer)), buyer, ).await; } // In the main function let order_id = msg .get_inner_message_kind() .id .context("Order ID is required")?; let order = Order::by_id(pool, order_id) .await? .context("Order not found")?; let seller_pubkey = PublicKey::from_str( order.seller_pubkey .as_ref() .context("Seller pubkey not found")?, )?; // Wrap status update and notifications in a transaction let mut tx = pool.begin().await?; if let Ok(order_updated) = update_order_event(my_keys, Status::FiatSent, &order).await { order_updated.update(&mut *tx).await?; notify_parties( order.id, &event.sender, &seller_pubkey, msg.get_inner_message_kind().request_id, ).await; tx.commit().await?; }src/app.rs (5)
39-43: LGTM! Consider adding more detailed documentation.The helper function provides consistent error logging. Consider adding documentation about the error format and when this helper should be used.
/// Helper function to log warning messages for action errors +/// +/// # Arguments +/// * `action` - The action that caused the error +/// * `e` - The error that occurred during action processing fn warning_msg(action: &Action, e: anyhow::Error) { tracing::warn!("Error in {} with context {}", action, e); }
46-54: Consider grouping related parameters into a context structThe function takes many parameters which could be grouped into a context struct for better maintainability and cleaner function signatures.
struct ActionContext<'a> { event: &'a UnwrappedGift, my_keys: &'a Keys, pool: &'a Pool<Sqlite>, ln_client: &'a mut LndConnector, rate_list: Arc<Mutex<Vec<Event>>>, }

124-129: Consider making the event age threshold configurableThe 10-second threshold for discarding old events is hardcoded. Consider making this configurable through settings, similar to how POW is handled.
+ // Get event age threshold from config + let event_age_threshold = Settings::get_mostro().event_age_threshold; let since_time = chrono::Utc::now() - .checked_sub_signed(chrono::Duration::seconds(10)) + .checked_sub_signed(chrono::Duration::seconds(event_age_threshold)) .unwrap() .timestamp() as u64;
133-146: Improve error handling specificityThe error handling could be more specific about what part of the action processing failed.
- if let Err(e) = handle_message_action( + let action_result = handle_message_action( &action, msg, &event, &my_keys, &pool, ln_client, rate_list.clone(), - ) - .await - { - warning_msg(&action, e) + ).await; + if let Err(e) = action_result { + warning_msg(&action, e.context("Failed to process message action")) }
Line range hint
108-152: Consider refactoring nested conditionsThe deeply nested if conditions make the code harder to follow. Consider extracting the validation logic into a separate function.
async fn validate_and_process_event( event: &Event, pow: u8, my_keys: &Keys, ) -> Result<Option<(Message, UnwrappedGift)>> { if !event.check_pow(pow) { tracing::info!("Not POW verified event!"); return Ok(None); } if event.verify().is_err() { tracing::warn!("Error in event verification"); return Ok(None); } let unwrapped = unwrap_gift_wrap(my_keys, event)?; // Check event age let since_time = chrono::Utc::now() .checked_sub_signed(chrono::Duration::seconds(10)) .unwrap() .timestamp() as u64; if unwrapped.rumor.created_at.as_u64() < since_time { return Ok(None); } let message = Message::from_json(&unwrapped.rumor.content)?; if !message.get_inner_message_kind().verify() { return Ok(None); } Ok(Some((message, unwrapped))) }

69-69: LGTM! Removing request_id for seller notification is correct.
The seller didn't initiate this action, so they don't need a request_id in their notification. This change aligns with the message handling refactoring.
Line range hint 14-92: Verify error handling in upstream code.
The function returns Ok(()) in several error cases (order not found, invalid status) instead of propagating errors. This might hide issues from upstream error handlers.
Let's check how errors are handled in the calling code:
src/app/admin_take_dispute.rs (3)
Line range hint 129-134: LGTM! Consistent message handling for both parties.
The message construction maintains symmetry between buyer and seller notifications, properly including the solver's public key in both messages.
Line range hint 136-143: LGTM! Robust error handling implementation.
The error handling for missing pubkeys is well-structured, using idiomatic Rust pattern matching and providing clear error messages.
122-127: Verify the impact of removing request_id from message construction.
The change to set request_id to None might affect message tracking. Let's verify if this change is consistent with the message handling across the codebase.
✅ Verification successful
Based on the shell script results, I can now make a definitive assessment. The request_id parameter in Message::new_order is used consistently across the codebase for message tracking and correlation. However, in the specific case of admin_take_dispute.rs, setting it to None is correct because:
- The code shows that other admin actions (
admin_settle.rs,admin_cancel.rs) use therequest_idfrom the incoming message for their responses. - In
admin_take_dispute.rs, these messages (msg_to_buyerandmsg_to_seller) are notifications sent to both parties about the dispute being taken, not responses to any specific request. - The pattern of using
Noneforrequest_idis consistent with other notification-style messages in the codebase where there isn't a direct request-response relationship.
The change to set request_id to None is correct for notification messages.
The modification aligns with the codebase's message handling patterns where notifications don't require request correlation.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Search for other instances of Message::new_order to verify consistency
ast-grep --pattern 'Message::new_order($$$)'
# Search for any request_id usage in message handling
rg -A 3 'request_id'

Critical: Replace todo!() with proper error handling
The PayInvoice action will cause a runtime panic. This should be properly handled or marked as unimplemented.
- Action::PayInvoice => todo!(),
+ Action::PayInvoice => {
+ tracing::warn!("PayInvoice action not implemented yet");
+ Ok(())

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🛠️ Refactor suggestion
Consider proper error handling for unknown actions
The catch-all pattern silently logs unknown actions at info level. Consider whether this should be a warning or error level log, and whether it should return an error result.
_ => {
- tracing::info!("Received message with action {:?}", action);
+ tracing::warn!("Received unknown action: {:?}", action);
+ Err(anyhow::anyhow!("Unsupported action type"))

@grunch ,
i was playing a bit with Cursor AI, on
app.rsit compacted the big loop in a nicer way imo.Take a look...
