Walkthrough

The changes in this pull request involve significant refactoring of the TransactionAspect class to enhance database operation handling within transactional contexts. New methods for managing read operations have been introduced, while existing logic has been modularized for clarity. Additionally, two new constants have been added to the FieldNameCE class to standardize action names across the application. Overall, the modifications improve the organization and maintainability of the code.

    • 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 gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
    • @coderabbitai read src/utils.ts and generate unit testing code.

    • @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.

32-32: Declare OBJECTID_PATTERN as static final

To avoid unnecessary instance creation and indicate that it's a constant, declare OBJECTID_PATTERN as private static final.

Apply this change:

-    Pattern OBJECTID_PATTERN = Pattern.compile("^[0-9a-fA-F]{24}$");
+    private static final Pattern OBJECTID_PATTERN = Pattern.compile("^[0-9a-fA-F]{24}$");

49-51: Extract MethodSignature to a local variable

You're casting joinPoint.getSignature() to MethodSignature multiple times. Extract it to a variable to improve readability and efficiency.

Example:

MethodSignature methodSignature = (MethodSignature) joinPoint.getSignature();
if (isReadOp(entityData, methodSignature)) {
    // ...
}

218-218: LGTM! Good addition for read operations.

The GET constant follows the naming pattern of other operation constants and aligns with the transaction read operations being implemented.

app/server/appsmith-server/src/main/java/com/appsmith/server/aspect/TransactionAspect.java (1)

67-67: Verify the default return when no conditions are met

Currently returning Mono.empty() or Flux.empty() if no conditions match. Confirm if this is intended or if you should proceed with the original method invocation.

⚠️ Potential issue

Remove duplicate constant SAVE.

The constant SAVE duplicates the existing CREATE constant (line 217) with the same value "save". Having two constants for the same operation can lead to inconsistent usage.

Apply this diff to remove the duplicate:

-    public static final String SAVE = "save";

And update any new code to use the existing CREATE constant.

⚠️ Potential issue

Add null check before updating transactionContext

Ensure id is not null before adding to transactionContext to prevent potential NullPointerException.

Apply this change:

-    transactionContext.putIfAbsent(id, dbOps);
+    if (id != null) {
+        transactionContext.putIfAbsent(id, dbOps);
