Walkthrough

The changes in this pull request focus on the VerificationServer class within VerificationServer.js. The start method has undergone significant modifications to enhance error handling, introducing a retry mechanism for container creation upon encountering a name conflict (409 error) and refining the logic for handling existing containers and error responses.

102-109: Consider adding exponential backoff between retries

While the retry logic is solid, adding a small delay between retries could help in scenarios where the container cleanup takes longer than expected.

 const MAX_RETRIES = 3;
+const RETRY_DELAY_MS = 1000;
 while (!this.container && retries <= MAX_RETRIES) {
   try {
     this.container = await this.docker.createContainer(opts);
   } catch (e) {
     // Throw any other error except container name conflict
     if (e.statusCode !== 409) {
       throw e;
     }
+    // Add exponential backoff
+    await new Promise(resolve => setTimeout(resolve, RETRY_DELAY_MS * Math.pow(2, retries)));

100-102: LGTM! Well-structured retry mechanism

The implementation of a retry mechanism with a reasonable maximum retry count (3) is a good approach to handle container name conflicts.

111-126: LGTM! Robust error handling for container cleanup

The error handling for container removal and waiting is well implemented:

• Properly handles dangling container removal
• Correctly distinguishes between 404 (container not found) and other errors
• Uses force removal to ensure cleanup succeeds
