Debugging with Git Bisect - Find Bugs Fast

Tracking down a bug in a large codebase can be frustrating. **Git bisect** helps by using a binary search to quickly find the exact commit that introduced the issue.


## Step 1: Start Git Bisect

Begin by starting bisect mode:

```sh

git bisect start

```


## Step 2: Mark a Good and Bad Commit

Specify a known working commit:

```sh

git bisect good a1b2c3d

```

Mark the current commit (where the bug exists) as bad:

```sh

git bisect bad

```


## Step 3: Test and Mark Commits

Git checks out a middle commit. Run your app and test it:

```sh

./gradlew bootRun

```

If the bug exists:

```sh

git bisect bad

```

If the bug is not present:

```sh

git bisect good

```


## Step 4: Find the Bad Commit

Once Git finds the problematic commit, it displays:

```sh

1234567 is the first bad commit

```


## Step 5: Reset Git Bisect

Once the issue is identified, reset bisect mode:

```sh

git bisect reset

```


## Conclusion

Using **git bisect** can save you hours when debugging! Instead of checking each commit manually, bisect efficiently pinpoints the issue in just a few steps.

Mastering Java Logging: A Guide to Debug, Info, Warn, and Error Levels

Comprehensive Guide to Java Logging Levels: Trace, Debug, Info, Warn, Error, and Fatal Comprehensive Guide to Java Logging Levels: Trace, Debug, Info, Warn, Error, and Fatal Logging is an essential aspect of application development and maintenance. It helps developers track application behavior and troubleshoot issues effectively. Java provides various logging levels to categorize messages based on their severity and purpose. This article covers all major logging levels: Trace , Debug , Info , Warn , Error , and Fatal , along with how these levels impact log printing. 1. Trace The Trace level is the most detailed logging level. It is typically used for granular debugging, such as tracking every method call or step in a complex computation. Use this level sparingly, as it can generate a large volume of log data. 2. Debug The Debug level provides detailed information useful during dev...

Choosing Between Envoy and NGINX Ingress Controllers for Kubernetes

As Kubernetes has become the standard for deploying containerized applications, ingress controllers play a critical role in managing how external traffic is routed to services within the cluster. Envoy and NGINX are two of the most popular options for ingress controllers, and each has its strengths, weaknesses, and ideal use cases. In this blog, we’ll explore: How both ingress controllers work. A detailed comparison of their features. When to use Envoy vs. NGINX for ingress management. What is an Ingress Controller? An ingress controller is a specialized load balancer that: Manages incoming HTTP/HTTPS traffic. Routes traffic to appropriate services based on rules defined in Kubernetes ingress resources. Provides features like TLS termination, path-based routing, and host-based routing. How Envoy Ingress Controller Works Envoy , initially built by Lyft, is a high-performance, modern service proxy and ingress solution. Here's how it operates in Kubernetes: Ingress Resource : You d...
