a transaction can have side effects which can spawn a new transaction, in the meantime a new transaction group could have been started already. Just piggyback on the existing transaction group if it exists.

Walkthrough

The changes primarily involve modifying various onLoaded methods across multiple classes to remove the async keyword, indicating that these methods will now execute synchronously instead of returning promises. Additionally, the TransactionBundler class's onCommitted property has been updated to reflect synchronous function types, simplifying the transaction handling process. These adjustments streamline method signatures and control flow throughout the codebase.

28-28: Review: Synchronous Execution of onLoaded

The removal of async from onLoaded changes its execution context to synchronous. Ensure all dependent asynchronous operations within this method and its callbacks are adjusted accordingly to prevent potential race conditions or deadlocks.

68-69: Change to synchronous execution approved; verify error handling.

The method onLoaded has been correctly updated to synchronous execution. Ensure that this change does not affect error handling negatively, especially in scenarios where onLoaded might throw exceptions or errors.


101-102: Change to synchronous execution approved; verify error handling.

The method onSaved has been correctly updated to synchronous execution. Ensure that this change does not affect error handling negatively, especially in scenarios where onSaved might throw exceptions or errors.

packages/sdk/src/sync-agent/user/models/userMemberships.ts (1)

40-40: Visibility change to protected approved; verify access requirements.

The method onLoaded has been correctly updated to protected, promoting encapsulation. Ensure that this change does not restrict access where it might be needed by other parts of the application or by subclasses.

packages/sdk/src/sync-agent/river-connection/models/riverChain.ts (1)

37-37: Visibility change to protected override approved; verify access requirements and overriding behavior.

The method onLoaded has been correctly updated to protected override, promoting encapsulation and clarifying its role in the class hierarchy. Ensure that this change does not restrict access where it might be needed by other parts of the application or by subclasses, and verify that it correctly overrides a method from the parent class.

packages/sdk/src/sync-agent/spaces/spaces.ts (1)

37-37: Approved change to synchronous execution in onLoaded.

The removal of async from onLoaded is approved as the method's logic does not inherently require asynchronous handling. However, ensure that this change does not affect other components expecting asynchronous behavior.

Verification successful

Synchronous onLoaded execution is safe. The change from asynchronous to synchronous execution in onLoaded does not negatively impact other components, as there is no evidence of asynchronous handling or awaiting of this method in the codebase.

Scripts executed

The following scripts were executed for the analysis:

Script:

#!/bin/bash
# Description: Verify that no other components are negatively impacted by the synchronous execution of `onLoaded`.

# Test: Search for method calls to `onLoaded` to ensure they handle synchronous execution correctly.
rg --type python -A 5 $'onLoaded'

Length of output: 63


Script:

#!/bin/bash
# Description: Verify that no other components are negatively impacted by the synchronous execution of `onLoaded`.

# Test: Search for method calls to `onLoaded` in TypeScript files to ensure they handle synchronous execution correctly.
rg --type ts -A 5 'onLoaded'

The removal of async from onLoaded is approved as the method's logic does not inherently require asynchronous handling. However, ensure that this change does not affect other components expecting asynchronous behavior.

Verification successful

Synchronous onLoaded Execution Verified

The change to synchronous execution in the onLoaded method does not negatively impact other components. The usage patterns across the codebase do not indicate any dependencies on asynchronous behavior.

  • Instances of onLoaded in various files show no asynchronous handling requirements.

21-21: Approved: Simplified transaction completion handling.

The change to a synchronous onCommitted array simplifies the transaction handling by removing asynchronous complexities.


74-74: Approved: Enhanced error messaging in transaction conflicts.

Including the name of the conflicting transaction in the error message aids in clearer debugging and operational transparency.


108-111: Approved: Synchronous execution of onCommitted functions.

Executing onCommitted functions synchronously aligns with the overall simplification of transaction processing, ensuring predictable execution order.

packages/sdk/src/sync-agent/members/members.ts (1)

26-26: Approved but verify asynchronous impacts.

Removing async simplifies the method but ensure that all operations within onLoaded that previously relied on asynchronous execution are properly adjusted.

packages/sdk/src/sync-agent/river-connection/riverConnection.ts (1)

71-71: Approved: Enhanced method encapsulation.

Changing onLoaded to protected improves encapsulation and prevents misuse from outside the class hierarchy.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

  • Review comments: Directly reply to a review comment made by CodeRabbit. Example:
    • I pushed a fix in commit <commit_id>.
    • Generate unit testing code for this file.
    • Open a follow-up GitHub issue for this discussion.
  • Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
    • @coderabbitai generate unit testing code for this file.
    • @coderabbitai modularize this function.
  • PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
    • @coderabbitai generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @coderabbitai read src/utils.ts and generate unit testing code.
    • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
    • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
