Important

Ensure dependencies are installed on project load by updating DBTProject and DBTCloudProjectIntegration classes.

  • Behavior:
    • DBTProject now installs dependencies on project load by calling installDeps() in rebuildManifest().
    • DBTCloudProjectIntegration's deps() method now executes dbt deps command and throws an error if stderr is present.
  • Functions:
    • rebuildManifest() in DBTCloudProjectIntegration no longer accepts retryCount parameter.
    • installDeps() in DBTProject is now asynchronous.
  • Misc:
    • Fix typo: pathsInitalized to pathsInitialized in DBTCloudProjectIntegration.

    • 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.

    Corrected a typo in the variable name from pathsInitalized to pathsInitialized. This change improves code readability and consistency.
  • Reason this comment was not posted:
    Confidence changes required: 10%
    The typo in the variable name 'pathsInitalized' was corrected to 'pathsInitialized'. This change is consistent with the rest of the code and improves readability.
2. src/dbt_client/dbtCloudIntegration.ts:395
  • Draft comment:
    Removed the unused retryCount parameter from rebuildManifest function, simplifying the function signature.
  • Reason this comment was not posted:
    Confidence changes required: 10%
    The rebuildManifest function had an unused retryCount parameter which was removed. This is a good change as it simplifies the function signature.
3. src/dbt_client/dbtCloudIntegration.ts:564
  • Draft comment:
    Updated the deps function to execute the command and handle errors properly, ensuring correct functionality.
  • Reason this comment was not posted:
    Confidence changes required: 10%
    The deps function was updated to execute the command and handle errors properly. This change aligns with the intended functionality of executing dbt commands and handling their output.
4. src/manifest/dbtProject.ts:658
  • Draft comment:
    Changed installDeps to be asynchronous, which is appropriate for handling I/O operations efficiently.
  • Reason this comment was not posted:
    Confidence changes required: 10%
    The installDeps function was changed to be asynchronous, which is appropriate given that it likely involves I/O operations that can benefit from async handling.
5. src/dbt_client/dbtCloudIntegration.ts:395
  • Draft comment:
    Please specify a return type for the rebuildManifest function to improve code readability and maintainability.
  • Reason this comment was not posted:
    Comment was on unchanged code.
6. src/dbt_client/dbtCloudIntegration.ts:233
  • Draft comment:
    Use an early return to simplify the logic in refreshProjectConfig by returning immediately if pathsInitialized is true.
  • Reason this comment was not posted:
    Comment was on unchanged code.
7. src/dbt_client/dbtCloudIntegration.ts:401
  • Draft comment:
    Use an early return after cancelling rebuildManifestCancellationTokenSource to reduce nesting in rebuildManifest.

🧹 Nitpick comments (1)
src/manifest/dbtProject.ts (1)

526-534: Consider enhancing error handling and logging.

While the dependency installation logic is sound, the error handling could be improved:

  1. The warning message could be more descriptive
  2. The error should be logged through the terminal service for consistency
  3. Consider notifying the user about dependency installation failures

Apply this diff to improve error handling:

  if (!this.depsInitialized) {
    try {
      await this.installDeps();
    } catch (error: any) {
-     // this is best effort
-     console.warn("An error occured while installing dependencies", error);
+     this.terminal.warn(
+       "DbtProjectDepsInstallation",
+       "Failed to install dependencies. Some features may not work correctly.",
+       true,
+       error
+     );
+     window.showWarningMessage(
+       "Failed to install dbt dependencies. Some features may not work correctly."
+     );
    }
    this.depsInitialized = true;
  }

src/dbt_client/dbtCloudIntegration.ts (3)

195-195: LGTM! Fixed typo in variable name.

The spelling correction from pathsInitalized to pathsInitialized improves code readability while maintaining the same functionality.

Also applies to: 236-240


398-398: LGTM! Simplified method signature.

The removal of the unused retryCount parameter simplifies the interface while maintaining the core functionality.


567-571: LGTM! Implemented deps command support.

The method now properly executes the deps command instead of throwing an unsupported error. This change enables dependency management in dbt cloud, which is essential for the PR's objective of performing db deps on project load.

src/manifest/dbtProject.ts (2)

111-111: LGTM! Added state tracking for dependency initialization.

The depsInitialized flag helps prevent redundant dependency installations by tracking the initialization state.


Line range hint 658-663: LGTM! Clean implementation of dependency installation.

The installDeps method is well-implemented with:

  • Proper telemetry tracking
  • Clear command creation and execution
  • Async/await pattern for handling promises
