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.

Option C is the correct implementation for the Sling Model. Option C uses the @Model annotation with the adaptables parameter set to Resource.class. This allows the Sling Model to adapt from a resource object and access its properties using the ValueMap interface. Option C also uses the @Inject annotation with the name parameter set to “./name” and “./occupations” to inject the values of the name and occupations properties into the name and occupations fields. Option C also uses the @Named annotation with the value parameter set to “byline” to specify the name of the Sling Model that can be used in HTL scripts. 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.

When performing an in-place upgrade to the latest version of AEM, there are several potential disadvantages to consider:

Long and Arduous Process:

The complexity and duration of the upgrade process can be significant, especially if there is a considerable version difference between the old and new AEM instances. This is because the upgrade process must account for all the changes and improvements made over multiple versions, including content structures, APIs, and underlying technologies.

Complex Developer Setup and Automation:

Upgrading AEM involves setting up and configuring the environment, updating custom code, and ensuring that all integrations work seamlessly. Automating these tasks can be complex and time-consuming, requiring significant developer effort to script and validate the upgrade process.

These disadvantages highlight the potential challenges and resource investments needed for an in-place upgrade.
