EZ-Merge

What is EZ-Merge?

Merging is simply putting a forked history back together again. Say we have a new branch feature based on the master branch. We now want to merge this feature branch into the master. Using the merge process in AutoRABIT will merge the specified branch feature into the current branch...we'll assume the master. 

Before you begin

Before a merge, several preparation steps must be taken to ensure the merge goes smoothly.

1. Register your Version Control Repository in AutoRABIT: An Admin can only perform this step. Register your Version Control Repositories, such as GIT, SVN, or TFS, in AutoRABIT. 
2. Register your Salesforce Organization in AutoRABIT: AutoRABIT connects to your Salesforce Org using the secure OAuth method or username/password connections. An Admin can only perform this step. 
3. Set Up a Branch: Instead of directly making changes to the code base, you can branch off from the mainline and work on a specific feature in an isolated branch. An Admin can only perform this step. 
4. Mapping the users with the Version Control and Salesforce Orgs in the "My Profile" section: Set up the permissions to create a project in AutoRABIT. 
5. Fetch the latest remote commits: Ensure the receiving branch and the merging branch are up to date with the latest remote changes.

How do I merge my changes to a branch?

The merge process is generally performed when a feature is ready for user testing in Salesforce Orgs and usually involves code review by other development team members.

1. Hover your mouse over the Version Control module and select Commits.
   
2. Click on the New EZ-Merge button.
   
   The New EZ-Merge screen is best viewed when the zoom setting is set to 80% on your Chrome/Firefox browser.
3. You can also reach the New Merge screen directly by selecting Create New > New EZ-Merge from the top navigation bar.
4. In the New EZ-Merge screen, select the version control repository from where the metadata components will be fetched.
5. Select your source (base) branch and the target branch.
   
6. Select the Merge Type from the dropdown:
   • Entire Branch 
   • Single Revision
   • Commit Label
   • Release Label
   • ALM Label

Merge Type

A. Entire Branch

This option will merge the entire change from one branch to another branch. 

Different options for "Entire Branch" merge type 

• Delete Source Branch: Once you have successfully merged the changes from the source branch to another, you can permanently delete the source branch. Select the Delete Source Branch checkbox to delete the source branch, which auto-populates whenever Entire Branch as a merge type is selected.
  

B. Single Revision

Merge a Single Revision from the Commits that you have performed. You can either enter the revision number (in case you remember it) or use the Search () button next to the Single Revision field to pull a list of revisions from which you can choose which revision to use in the deployment.
 

There could be a situation where you have entered an incorrect revision number and hit the Search button. In this case, an error message indicates that the revision number entered is incorrect.

You can also use the 'Get All Revisions' button to try and get all the revisions and check for your revision from the list.

C. Commit Label

Select the commit labels created while committing to Version Control System. The commit labels created during the EZ-Commit or Merge process will be fetched in the Commit Label field.

For example, DXTES-19_EZ-Commit, here DXTES-19 indicates the commit label name, and EZ-Commit denotes the label created during the EZ-Commit process.

Click on the View Revisions link to view the list of revisions for the commit label. A new dialog box appears with the revisions, date/time stamp, comments, and author details. There is a provision to search for specific revisions using the Revision Search filter on the top right corner of the dialog box.

D. Release Label

You can select the release labels created using the committed revisions and the labels.

1. Select the Merge Type as Release Label.
2. The Release Labels field populates with all the available release labels in that repository/branch. If no release label is created for the above repository/ branch, an error notification states, "No Release Labels found."
3. Select your Release Label. 
4. Click on the View Revisions link to view the list of revisions for the release label. A new dialog box appears with the revisions, date/time stamp, comments, and author details. There is a provision to search for specific revisions using the Revision Search filter on the top right corner of the dialog box.
   

E. ALM Label

This allows you to choose and promote the ALM user stories to a higher or lower branch.

1. Select the Merge Type as ALM Label.
2. The Work Item will gather all the user stories for which the ALM commits happened in the Source Branch of chosen Version Control Repository. Click on the Search () icon to find the list of user stories or work items fetched.
   
   Note:

   You will not have the option to enter the work item details manually, you need to select the work item from the list fetched.
3. Select one of the work items from the list fetched, and click OK.
   

More Options:

1. Conflict Resolution Strategy: This field allows you to select how to resolve the conflicts. If you and another user change the same file in different sandboxes or on different branches, a conflict arises when you try to commit your modified files. When the conflict occurs, AutoRABIT will use the below resolve method:
   1. Manually resolve conflicts: Resolve the conflicts manually.
   2. Choose the file from the source: Replaces the copy of the file in your workspace with the version in the repo, discarding your changes. 
   3. Choose the file from the destination: Accept the file in your workspace, overwriting the version in the repo when you submit the file.
2. Enter the Merge Label name and comment (if any).
3. Enter the Email ID(s) to send an email notification of the merge reports.
4. Create Commit Label: To create a commit label for the merge operation, select this checkbox.
5. Create a GIT Tag: GIT tags are a simple and effective way to ensure you can keep track of the different versions of your code and the critical quality of Git's version control. GIT Tag operation allows meaningful names to a specific version in the repository.
6. Skips Profile/ Perm. Set Access-Setting Duplicity Check: If you do not want AutoRABIT to list all duplicate entries for your profile/permission sets, please select this checkbox. (Learn More)
7. Review Artifact: Select this checkbox to see the list of the changed files staged for commit (during merge conflicts). This allows you to preview the changes, review them or edit the files before pushing them into your version control. (Learn More)

Prevalidate Merge

In this section, you can assign certain pre-validation merge operations (such as deployment validation with another Salesforce Org, choosing the Apex test class to run, selecting the static code analysis tool, generating difference reports, etc) before merging it to your target branch.

Different Prevalidate Merge Criteria:

1. Generate Diff Report: Select this option to auto-generate a code difference report on completion of the commit.
2. Run Static code Analysis: Select this option if you want to run a static code analysis tool to identify potential software quality issues before the code moves to production. Similar to "Generate Diff Report," this option will also be auto-selected by default if the criteria are set globally (under the My Account > Commit Validation - Approval Settings section).
   • For ApexPMD, Checkmarx, CodeScan, and SonarQube: AutoRABIT allows you to set the criteria for running the SCA tool, whether to run on all supported metadata types from the full source or to run on the newly added components.
     
     Important Note:

     Whenever a code analysis is triggered, ARM will wait up to 5 hours for a response. If the code analysis is not completed within 5 hours, ARM will throw a timeout exception error. This applies to all SCA tools.
3. Validate Deployment: Choose a Salesforce org to validate a future deployment. Further, there are different options to choose from:
   1. Run Destructive Changes: Here, you can specify whether to run pre or post-destructive changes while carrying out the merge process.
   2.  Ignore Missing Visibility: With this option, differences in visibility settings between the source and destination branches will not cause the merge to fail. AutoRABIT will compare the source and destination branches and keep only the common settings between both branches.
      
      Important Note

      Standard fields are not supported for Ignore Missing Visible Settings.

      
      
      
      
   3. Ignore installed components: When selected, AutoRABIT will scan for the components that are deployed, and if there are any managed package components located in the destination branch, these components will be excluded from the metadata.zip files while the remaining components are deployed. 
   4. Apex Test Level: Choose your Apex Test level to validate your merge.
      

ALM Integration

You can update the status of the ALM work item through the ALM Integration section (below the Pre-validate Merge section), and the same gets reflected in your ALM system.

1. Select the ALM label.
2. Select the Project and the sprint for which the commit is planned.
3. Select the Work Item, and the Current Status for the work item gets auto-populated. This allows you to update the ALM for the Merge operation with or without changing the current work item status. Click on the + icon to add another work item and update its status.
   

Click on either Dry Run or Validate & Merge.

• A notification appears that the merge request has been submitted for Entire Branch and Single Revision merge types. Click OK, and you will be auto-redirected to the Commits screen, where you can find the status of the initiated merge.
  
• A confirmation dialog box will ask you to approve the requested operation for Release Label, Commit Label, and ALM Label merge types. Click OK, and you will be auto-redirected to the Commits screen, where you can find the status of the initiated merge.
  

Troubleshooting

For merge labels that are either in progress or have some conflicts, in such a scenario, you will find a popup that will appear as shown below when you press the Validate & Merge button. These merge conflict statuses will only be shown for the merges created within seven days.

Resolution: To prevent this, first, resolve current merge conflicts or allow the in-progress merge status to move to the completed state and then restart the merge process again.
