crates/torii/migrations/20240923155431_last_block_timestamp.sql (1)
1-2: Ohayo, SQL sensei! Your migration looks solid, but let's level up!The addition of the
last_block_timestampcolumn is a great move for TPS calculations. Here are some thoughts to make it even more sugoi:
- Consider adding a NOT NULL constraint with a DEFAULT value. This ensures data integrity for existing and new rows.
- If you need precise timing, a TIMESTAMP type might be more appropriate than INTEGER.
- Depending on your query patterns, an index on this column could boost performance if it's used in WHERE clauses or joins.
What do you think, sensei? Want to power up this migration even further?
Here's a potential power-up for your consideration:
-- Add last_block_timestamp column for TPS calculation ALTER TABLE contracts ADD COLUMN last_block_timestamp TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP; CREATE INDEX idx_contracts_last_block_timestamp ON contracts(last_block_timestamp);This version uses TIMESTAMP, adds a NOT NULL constraint with a default value, and creates an index for potential performance benefits.

88-94: Ohayo, sensei! The newIndexerUpdatestruct looks good!The addition of the
IndexerUpdatestruct aligns well with the PR objective of adding a TPS metric to the contracts table. The fields chosen are appropriate for tracking indexer updates.A few suggestions to consider:
- If this struct will be used in database operations or API responses, you might want to derive
Serialize,Deserialize, andFromRowtraits.- Consider adding documentation comments to explain the purpose of each field, especially
tpsandhead.Would you like me to provide an example of how to add these traits and documentation, sensei?
crates/torii/grpc/proto/world.proto (1)
49-55: Ohayo, sensei! This message is packed with goodies!The
SubscribeIndexerResponsemessage is well-structured and provides comprehensive indexer status information. Great job including thetps(transactions per second) field - it's a valuable addition that wasn't explicitly mentioned in the PR objectives.Consider adding a brief comment for each field to explain their purpose, especially for
headandtps, as their meanings might not be immediately clear to all developers.crates/torii/grpc/src/types/mod.rs (2)
19-25: Ohayo, sensei! TheIndexerUpdatestruct looks great!The new
IndexerUpdatestruct is well-designed and contains all the necessary fields for representing indexer updates. The choice of types for each field is appropriate, and the derived traits provide useful functionality.Consider adding a brief doc comment to explain the purpose of this struct and possibly describe each field. For example:
/// Represents an update from an indexer. /// /// # Fields /// * `head` - The current head block number. /// * `tps` - Transactions per second. /// * `last_block_timestamp` - Timestamp of the last processed block. /// * `contract_address` - The address of the contract being indexed. #[derive(Debug, Serialize, Deserialize, PartialEq, Hash, Eq, Clone)] pub struct IndexerUpdate { // ... existing fields ... }This will help other developers understand the purpose and usage of this struct at a glance.
27-36: Ohayo again, sensei! TheFromimplementation looks solid!The implementation for converting
proto::world::SubscribeIndexerResponsetoIndexerUpdateis straightforward and correct. It properly maps all fields and handles the conversion ofcontract_addressfrom bytes to aFelt.Consider adding error handling for the
contract_addressconversion. While it's likely that the input will always be valid, it's generally a good practice to handle potential errors. You could useTryFrominstead ofFromto allow for error handling. Here's an example:impl TryFrom<proto::world::SubscribeIndexerResponse> for IndexerUpdate { type Error = &'static str; fn try_from(value: proto::world::SubscribeIndexerResponse) -> Result<Self, Self::Error> { Ok(Self { head: value.head, tps: value.tps, last_block_timestamp: value.last_block_timestamp, contract_address: Felt::from_bytes_be_slice(&value.contract_address) .map_err(|_| "Invalid contract address")?, }) } }This approach allows for more robust error handling and makes it clear that the conversion might fail.

44-46: Clarify Comment Regarding Unlock Issue with BrowsersOhayo sensei! The comment
// NOTE: unlock issue with firefox/safarilacks context, making it difficult for others to understand its significance.Please expand the comment to explain the specific issue with Firefox and Safari browsers and how sending an initial empty response resolves it. For example:
// NOTE: Sending an initial response to prevent connection hang in Firefox and Safari. // These browsers expect an immediate response to establish the stream properly.This clarification aids in maintaining the code by providing necessary background.

Potential Resource Exhaustion Due to Unbounded Task Spawning
Ohayo sensei! In the poll method, spawning a new task for every event without limit could exhaust system resources if events are frequent.
Consider implementing a concurrency limit or processing events within a fixed-size thread pool. This can be achieved using tokio::spawn with a semaphore or utilizing tokio::sync::mpsc channels to control task spawning.

🛠️ Refactor suggestion
Optimize Subscriber Lookup for Improved Performance
Ohayo sensei! Iterating over all subscribers to match the contract_address can become inefficient as the subscriber count grows.
To enhance performance, consider indexing subscribers by contract_address. Modify the subscribers structure as follows:
-pub struct IndexerManager {
- subscribers: RwLock<HashMap<usize, IndexerSubscriber>>,
+pub struct IndexerManager {
+ subscribers: RwLock<HashMap<Felt, HashMap<usize, IndexerSubscriber>>>,
}Update the add_subscriber and publish_updates methods to accommodate this new structure. This change allows for quicker access to relevant subscribers based on the contract_address.

Potential ID Collision with Random Subscriber IDs
Ohayo sensei! Generating subscriber IDs using rand::thread_rng().gen::<usize>() may lead to collisions, causing unexpected behavior if duplicate IDs are assigned.
Consider using an atomic counter to ensure unique subscriber IDs. Apply this diff to address the issue:
+use std::sync::atomic::{AtomicUsize, Ordering};
+static SUBSCRIBER_ID_COUNTER: AtomicUsize = AtomicUsize::new(1);
-let id = rand::thread_rng().gen::<usize>();
+let id = SUBSCRIBER_ID_COUNTER.fetch_add(1, Ordering::Relaxed);This change guarantees that each subscriber receives a unique ID, preventing potential collisions.

Ohayo! Potential underflow and division by zero in TPS calculation
Sensei, in the calculation of tps, subtracting previous_block_timestamp from set_head.last_block_timestamp without checking for underflow may lead to incorrect results or panic in debug mode. If set_head.last_block_timestamp is less than previous_block_timestamp, the subtraction will underflow. Consider using checked_sub to safely handle this scenario.
Apply this diff to prevent underflow:
+let time_diff = set_head.last_block_timestamp.checked_sub(previous_block_timestamp).unwrap_or(0);
+let tps: u64 = if time_diff != 0 {
+ set_head.txns_count / time_diff

Ohayo, sensei! Should world_txns_count and contract_address be included in the SQL update?
Currently, the SQL statement only updates head and last_block_timestamp in the contracts table. If world_txns_count and contract_address need to be persisted in the database, consider including them in the update query.

1-2: Ohayo, sensei! The new column looks good, but let's think about existing data.The addition of the
last_block_timestampcolumn is a solid move for TPS calculation. However, we might want to consider how this affects existing rows in thecontractstable.Consider adding a DEFAULT value or updating existing rows to ensure consistency across all records. For example:
ALTER TABLE contracts ADD COLUMN last_block_timestamp INTEGER DEFAULT 0; -- And then update existing rows if needed UPDATE contracts SET last_block_timestamp = /* some appropriate value */ WHERE last_block_timestamp IS NULL;
3-3: Ohayo again, sensei! The TPS column is a nice addition, but let's make it crystal clear.Adding the
tpscolumn is a great idea for tracking performance metrics. However, we can improve on this a bit.Consider these enhancements:
- Add a comment explaining the purpose of the
tpscolumn, similar to thelast_block_timestampcolumn.- Specify a DEFAULT value to handle existing and new rows consistently.
- Consider using a more precise data type if decimal precision is needed for TPS.
Here's an example of how you might implement these suggestions:
-- Add TPS (Transactions Per Second) column for performance tracking ALTER TABLE contracts ADD COLUMN tps INTEGER DEFAULT 0; -- Or if decimal precision is needed: -- ALTER TABLE contracts ADD COLUMN tps NUMERIC(10, 2) DEFAULT 0.0;

1-3: Ohayo once more, sensei! Let's zoom out and look at the big picture.These changes are laying the groundwork for some cool TPS tracking functionality. Nice work! However, let's consider a few things to ensure smooth sailing:
- Application Code: Make sure any related application code is updated to use these new columns effectively.
- Data Migration: Consider how to handle existing data. You might want to backfill these columns with appropriate values.
- Performance Impact: Keep an eye on how these additional columns affect query performance, especially if the
contractstable is large or frequently accessed.- Documentation: Update any relevant documentation to reflect these new columns and their purpose.
To ensure we're not missing any important details, let's run a quick check on the existing schema:
This will help us understand the current state of the schema and ensure we're not duplicating any existing functionality.

17-18: Ohayo! LGTM for the import changes, sensei!The import statements have been updated correctly to include
Contract as ContractUpdated. This change aligns with the new functionality being added.
34-34: Ohayo! New BrokerMessage variant looks good, sensei!The addition of
SetHead(ContractUpdated)to theBrokerMessageenum is spot-on. It's a necessary change to support the new blockchain head update functionality.
49-56: Ohayo! New SetHeadQuery struct is well-crafted, sensei!The
SetHeadQuerystruct is a solid addition. It contains all the necessary fields for setting the blockchain head, with appropriate types for each field. Nice work on structuring this data!
59-59: Ohayo! QueryType enum update is on point, sensei!The addition of
SetHead(SetHeadQuery)to theQueryTypeenum is a perfect complement to the newSetHeadQuerystruct. This change enables the system to handle the new query type for setting the blockchain head.

Ohayo! Watch out for that sneaky i64 to u64 conversion, sensei!
The conversion from i64 to u64 for previous_block_timestamp could fail if the value is negative. Consider using a safe conversion method or handling potential errors. Here's a suggestion:
let previous_block_timestamp: u64 = sqlx::query_scalar::<_, i64>(
"SELECT last_block_timestamp FROM contracts WHERE id = ?"
)
.bind(format!("{:#x}", set_head.contract_address))
.fetch_one(&mut **tx)
.await?
.try_into()
.map_err(|_| anyhow::anyhow!("Last block timestamp is negative or doesn't fit in u64"))?;This approach will provide a more informative error message if the conversion fails.

| set_head.txns_count / (set_head.last_block_timestamp - previous_block_timestamp) | ||
| } else { | ||
| set_head.txns_count | ||
| }; |

🛠️ Refactor suggestion
Ohayo! Let's make that TPS calculation more robust, sensei!
The current TPS calculation might not handle edge cases well. Consider using a more precise calculation method that avoids potential issues with integer division. Here's a suggestion:
let time_diff = set_head.last_block_timestamp.saturating_sub(previous_block_timestamp);
let tps = if time_diff > 0 {
(set_head.txns_count as f64 / time_diff as f64).round() as u64
} else {
0 // or another appropriate default value
};This approach uses floating-point division for more precise results and handles the case where time_diff is zero or when set_head.last_block_timestamp is less than previous_block_timestamp.

694-701: LGTM with suggestion: Newsubscribe_indexermethod added.Ohayo, sensei! The new
subscribe_indexermethod looks good and matches the description in the summary. However, we should improve the error handling when converting thecontract_address.Consider adding explicit error handling for the
Felt::from_bytes_be_sliceconversion. Here's a suggested improvement:async fn subscribe_indexer( &self, contract_address: Felt, ) -> Result<Receiver<Result<proto::world::SubscribeIndexerResponse, tonic::Status>>, Error> { - self.indexer_manager.add_subscriber(&self.pool, contract_address).await + self.indexer_manager + .add_subscriber(&self.pool, contract_address) + .await + .map_err(|e| Error::Custom(format!("Failed to add indexer subscriber: {}", e))) }This change will provide more context if the subscription fails.
1027-1059: LGTM with suggestion: New indexer subscription functionality added.Ohayo once more, sensei! The new type alias and implementation of
subscribe_indexerfor theWorldtrait look good. They're consistent with the new indexer functionality we're adding. However, we should improve the error handling when converting thecontract_address.Consider adding explicit error handling for the
Felt::from_bytes_be_sliceconversion. Here's a suggested improvement:async fn subscribe_indexer( &self, request: Request<SubscribeIndexerRequest>, ) -> ServiceResult<Self::SubscribeIndexerStream> { let SubscribeIndexerRequest { contract_address } = request.into_inner(); + let contract_felt = Felt::from_bytes_be_slice(&contract_address) + .map_err(|e| Status::invalid_argument(&format!("Invalid contract address: {}", e)))?; let rx = self - .subscribe_indexer(Felt::from_bytes_be_slice(&contract_address)) + .subscribe_indexer(contract_felt) .await .map_err(|e| Status::internal(e.to_string()))?; Ok(Response::new(Box::pin(ReceiverStream::new(rx)) as Self::SubscribeIndexerStream)) }This change will provide more specific error information if the contract address is invalid.

1-22: LGTM! Imports and constant look good.Ohayo sensei! The imports cover all the necessary dependencies for the implemented functionality. The
LOG_TARGETconstant is well-defined for logging purposes.
24-30: LGTM! IndexerSubscriber struct is well-defined.Ohayo sensei! The
IndexerSubscriberstruct is nicely designed with acontract_addressof typeFeltand asenderfor responses. This structure should effectively manage individual subscriptions.
77-87: LGTM! Service struct is well-designed.Ohayo sensei! The
Servicestruct is nicely defined with anArc<IndexerManager>for shared ownership and a boxed stream for flexibility. Thenewmethod provides a clean initialization process.
1-140: Overall, a well-implemented subscription system with room for optimization.Ohayo sensei! The implementation of the indexer subscription system is solid and makes good use of async Rust features. The code is well-structured and handles concurrency appropriately.
There are a few areas for potential optimization:
- Subscriber ID generation could be made deterministic.
- Subscriber lookup could be optimized for better performance with large numbers of subscribers.
- Concurrency limits could be implemented in the
Futureimplementation to prevent potential resource exhaustion.These optimizations would further enhance the robustness and scalability of the system. Great work overall!
32-74:⚠️ Potential issueConsider using a deterministic ID generation method.
Ohayo sensei! The
IndexerManagerstruct and its implementation look good overall. However, there's a potential issue with the subscriber ID generation:let id = rand::thread_rng().gen::<usize>();This random ID generation could lead to collisions, especially as the number of subscribers grows. Consider using a deterministic method, such as an atomic counter:
use std::sync::atomic::{AtomicUsize, Ordering}; static SUBSCRIBER_ID_COUNTER: AtomicUsize = AtomicUsize::new(1); // In add_subscriber method let id = SUBSCRIBER_ID_COUNTER.fetch_add(1, Ordering::Relaxed);This approach ensures unique IDs and avoids potential collisions.
89-120: 🛠️ Refactor suggestionConsider optimizing subscriber lookup.
Ohayo sensei! The
publish_updatesmethod looks good overall, but there's room for performance improvement:for (idx, sub) in subs.subscribers.read().await.iter() { if sub.contract_address != Felt::ZERO && sub.contract_address != contract_address { continue; } // ... rest of the code }This approach iterates over all subscribers, which could become inefficient as the number of subscribers grows. Consider indexing subscribers by
contract_addressto allow for quicker lookups:pub struct IndexerManager { subscribers: RwLock<HashMap<Felt, HashMap<usize, IndexerSubscriber>>>, }You'll need to update the
add_subscriberandpublish_updatesmethods accordingly, but this change could significantly improve performance for large numbers of subscribers.
123-140:⚠️ Potential issueConsider implementing a concurrency limit.
Ohayo sensei! The
Futureimplementation forServicelooks good, but there's a potential issue:while let Poll::Ready(Some(event)) = pin.simple_broker.poll_next_unpin(cx) { let subs = Arc::clone(&pin.subs_manager); tokio::spawn(async move { // ... task code }); }Spawning a new task for every event without limit could exhaust system resources if events arrive frequently. Consider implementing a concurrency limit or processing events within a fixed-size thread pool. You could use
tokio::spawnwith a semaphore ortokio::sync::mpscchannels to control task spawning.crates/torii/grpc/src/server/mod.rs (5)
20-21: LGTM! New imports added.Ohayo, sensei! The new imports for
RetrieveEntitiesRequestandRetrieveEntitiesResponselook good. They're likely related to new entity retrieval functionality.
32-32: LGTM! New import for IndexerManager.Ohayo again, sensei! The new import for
IndexerManagerlooks good. It seems we're adding some indexer management functionality to our codebase.
51-51: LGTM! New imports for indexer subscription.Ohayo once more, sensei! The new imports for
SubscribeIndexerRequestandSubscribeIndexerResponseare in line with the indexer functionality we're adding. Everything looks good here.
Line range hint
89-131: LGTM! IndexerManager added to DojoWorld.Ohayo, sensei! The addition of
indexer_managerto theDojoWorldstruct and its initialization look good. The new task spawned for the indexer service follows the existing pattern for other managers. These changes are consistent with the new indexer functionality we're implementing.
137-137: LGTM! Method renamed frommetadatatoworld.Ohayo, sensei! The renaming of the method from
metadatatoworldlooks good and aligns with the summary provided. However, we should ensure that all calls to this method are updated throughout the codebase.Let's verify the usage of this method across the codebase:
