Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads. References:

To debug a CQ HTML client library in the AEM author instance, you need to add the query parameter debugClientLibs set to true. This parameter instructs AEM to include additional debugging information for client libraries, making it easier to troubleshoot issues with JavaScript, CSS, and other assets.

Steps to enable client library debugging:

Open the AEM Page: Navigate to the AEM page where you want to debug the client libraries.

Append the Query Parameter: Add ?debugClientLibs=true to the URL. For example:

Reload the Page: Refresh the browser page. AEM will now include debugging information for client libraries.

This parameter helps in identifying issues with client library loading, dependencies, and other client-side resources.

To push a code fix into the current release candidate, the best practice is to cherry-pick the fix commit into the release candidate branch. Cherry-picking allows you to apply specific changes from one branch to another, ensuring that only the necessary fixes are included without introducing unrelated changes.

Here’s how to cherry-pick a commit:

Identify the Commit: Locate the commit hash of the fix you need to apply. This can be found in your version control system (e.g., Git).

Checkout the Release Candidate Branch:

git checkout release-candidate-branch

Cherry-pick the Commit:

git cherry-pick

Resolve Conflicts(if any): If there are conflicts, resolve them manually and then continue the cherry-pick process:

git add

git cherry-pick --continue

 Test the Changes: Ensure that the changes are tested thoroughly in the release candidate environment to confirm the fix works as expected.

 Push the Changes:

git push origin release-candidate-branch

Cherry-picking ensures that only the required changes are applied to the release candidate, maintaining the stability and integrity of the codebase.
