What happened

While analyzing the data gathered from our GitHub integration, I stumbled upon an anomaly in a minor subset of deployments. Oddly enough, some deployments were reporting a deployment of incosistent time (in my example 30 weeks).
Given my familiarity with our GitHub operations, I was certain this wasn't accurate, prompting me to dig deeper. My investigation points towards a potential issue with the getDeploymentCommit function, particularly in relation to EnrichPrevSuccessDeploymentCommit.

To illustrate, I've attached an example PR

{

As you can see this PR was merged 2024-04-05 09:00:16 yet the deployment linked is incorrect, as it belongs to a different deployment.

Manually checking in the cicd_deployment_commits for the merge_commit_sha (b297c73092685c4b1a0ee62c2326d77115a86e94) I can see that the deployment is there:

Upon inspection, I've noticed that the prev_success_deployment_commit_id field is empty in our data. I suspect this might be influencing the results of the query in the change_lead_time_calculator.go module.

I'm uncertain if the query should return null when faced with this condition, given that prev_success_deployment_commit_id is consistently empty for the first deployment recorded for the cicd_scope_id/repo_url/env grouping, as per code.

Interestingly, the linked "deployment_commit_id" : "github:GithubRun:4:435823930:11612162783 is the final entry in the cicd_deployment_commits table for the cicd_scope_id/repo_url/env grouping.

What do you expect to happen

PR deployment should be linked to the proper run for this example (github:GithubRun:4:435823930:8567339272:https:\/\/github.com\/l*****\/****)

How to reproduce

I will just describe what the status of that repo is, GitHub, deployment through CI/CD workflow, explore for the first PR deployment recorded by Devlake and evaluate the linked deployment.
This issue is only related to the first deployment for each cicd_scope_id/repo_url/env grouping.

Hello @kostas-petrakis! I'm here to help you with any bugs, questions, or contributions you have. Let me know how I can assist you while we wait for a human maintainer.

The issue you're encountering seems to be related to how the getDeploymentCommit function handles cases where the prev_success_deployment_commit_id is empty. This situation typically occurs for the first deployment in a cicd_scope_id/repo_url/env grouping, as the EnrichPrevSuccessDeploymentCommit function resets this field to an empty string for the first deployment in a new set of consecutive deployments [1].

In the change_lead_time_calculator.go module, the logic for selecting the deployment commit might not be correctly handling cases where prev_success_deployment_commit_id is empty, leading to incorrect deployment references being linked. This could explain why the deployment time is inaccurately reported as 30 weeks.

To address this, you might need to adjust the logic in the getDeploymentCommit function to ensure it correctly identifies and links the first deployment in such groupings. This could involve modifying the query to account for cases where prev_success_deployment_commit_id is empty and ensuring it selects the appropriate deployment commit for the first deployment scenario.

Since this issue is specific to the first deployment in each grouping, reviewing and potentially updating the logic in both the getDeploymentCommit and EnrichPrevSuccessDeploymentCommit functions to handle these edge cases more effectively would be a good starting point.
