Review display

During a code review, reviewers spend most of their time using the review interface.

By default, when you open the Review page for the first time, the file list panel and the information panel are hidden. Use the Show more context buttons to view the file list panel and the information panel.

For more information about the show more context buttons, see File diff panel.

Swarm supports stream specs in your workspace using the Private editing of streams feature. If a changelist or review contains a stream spec, it will be displayed first in Files with the prefix stream: //, for example: stream://MyStreamDepotName/MyStreamSpecLocationName. A changelist/review can only contain one stream spec.

The review interface is very similar to the changelist interface; and provides largely the same functionality, but has several notable differences that are described in the following sections.

Review state

The state of the review is displayed in the review description header. A review can be in one of the following states:

• Needs review: The review has started and the changes need to be reviewed.
• Needs revision: The changes have been reviewed and the reviewer has indicated that further revisions are required.
• Approved: The review has been approved. The changes may need to be committed.

• Rejected: The review has been completed. The changes are undesirable and should not be committed.
• Archived: The review has been completed for now but it is not rejected, or approved. The review has been filed away in case it is needed in the future.

For information about review states, see States.

Vote buttons

The vote buttons are in the review description header. Click a vote button to vote the review up or down. If you have already voted on the review, the vote button you clicked is highlighted. Clicking the button again, clears your vote. If you are not a member of a review, voting on the review adds you as a reviewer.

Stale votes

When a review is updated, if the review's list of files, file content, or file-types changes, any votes cast on the review become stale. The vote counts are reset, and the vote indicators become muted.

If you hover your mouse over a reviewer with a stale vote, a tooltip appears displaying the userid, how they voted, and on which version of the review; each version is represented as a point on the Select review versions to view.

Change state button

The Change state button is also used to change the state of the review. Click to select a new state from the dropdown menu. State change options are only displayed if you are authorized to make the state change:

• Needs revision: Select to request changes to the files in the review.
• Needs review: Select to request further review of the changes.
• Approve (only available if the voting requirements for the review are satisfied. For information on voting requirements, see Required reviewers): select to approve the review.
• Commit (only available for pre-commit reviews that have been approved): Select to commit the review.

For information about changing the state of a review, see States.

Review actions button

The Review actions button gives you access to more actions you can perform on the review. Not all of these actions are available to you, the actions available to you depend on your role on the review, the review type, and what is enabled on your Swarm system:

• Add change

• Download zip

• Change the review author

• Obliterate a review

• Join or leave a review

• Mark all comments for the review as read

• Mark all comments for the review as unread

• Refresh projects

• Disable notifications

• Deployment status

Add change

Once a review has been started you can add a changelist to the review. It can be useful to add changelists to an existing review. For example, if follow up changes are made to files in a review or if you need to group a number of changelists under a single review.

By default, for a pre-commit or a post-commit review, when a changelist is updated, all of the files in the review are replaced with the files in the changelist you are adding to the review. See Replace review with a pending changelist.

The Add change option in the Review actions button is used to add a changelist to an existing review. The option is not available if the review is in a state that is protected from change by the review workflow rules. For details of the On update of a review in an end state rule, see Workflow rules.

The options available for the Add change option depend on whether the review is pre-commit or post-commit:

• Pre-commit reviews:
  • Append pending changelist: when you add a pending changelist to a review, the files in the changelist are appended to the existing files in the review. See Append a pending changelist to a review.
  Note

  A review can only contain 1 stream spec. If you append a changelist with a stream spec to a review that already contains a stream spec, the spec in the changelist replaces the original one in the review. If it is a different spec from the original spec in the review, Swarm cannot display the diff between them and displays File content unchanged.

  • Replace with pending changelist: when you add a pending changelist to a review, all of the files in the review are replaced with the files in the changelist you are adding to the review. See Replace review with a pending changelist.
  • Replace with committed changelist: when you add a committed changelist to a review, all of the files in the review are replaced with the files in the changelist you are adding to the review. See Replace review with a committed changelist.
  Note

  If you replace a pre-commit review with a committed changelist, the new version of the review will be a post-commit review.

• Post-commit reviews:
  • Replace with pending changelist: when you add a pending changelist to a review, all of the files in the review are replaced with the files in the changelist you are adding to the review. See Replace review with a pending changelist.
  Note

  If you replace a post-commit review with a pending changelist, the new version of the review will be a pre-commit review.

  • Replace with committed changelist: when you add a committed changelist to a review, all of the files in the review are replaced with the files in the changelist you are adding to the review. See Replace review with a committed changelist.

Download zip

The Download zip option is available from the Review actions button and is used to download a ZIP archive containing all of the files in the review. The file revisions of the downloaded files are the file revisions in the most recent review version selected in the review version selector. See Select review versions to view.

When you select the Download zip option, Swarm performs the following steps:

1. Scans the files/folders:
   • Checks that you have permission to access their contents, according to the Helix Core Server protections.
   • Checks that the total file size is small enough to be processed by Swarm.
2. Syncs the file contents to the Swarm server from the Helix Core Server.
3. Creates the ZIP archive by compressing the file content.
4. Starts a download of the generated ZIP archive.

Change the review author

If the author of a review is no longer available, or ownership of a review is passed to a different developer, it is useful to be able to change the author of that review.

To change the author of a review:

1. Click the Review actions button.

2. Select Change author.

3. Select the new review author from the user list.

4. Click Save to change author of the review.

Obliterate a review

Obliterate is used to permanently delete reviews that have been created by mistake. For instance, if a review is associated with the wrong changelist, or a review contains sensitive information that should not be openly available.

For information on what happens to a review when it is obliterated, see When you obliterate a review.

To obliterate a review:

1. Navigate to the review.
2. Click the Review actions button and select Obliterate Review.
3. Click Yes on the confirmation dialog to complete the obliterate action.
4. The review is obliterated.

Join or leave a review

The option available depends on whether you are a reviewer on the review or not.

Join a review

1. Open the review you want to join.

2. Click the Review actions button.

3. Select Join review from the dropdown menu. Alternatively, you can Vote Up or Vote Down the review.

Your name is added to the Reviewers list in the Information panel, and you are now a reviewer.

Leave a review

1. Log in, if you have not already done so.

2. Open the review you want to leave.

3. Click the Review actions button.

4. Select Leave review from the dropdown menu.

   Your name is removed from the Reviewers list in the Information panel, and you are no longer a reviewer.

3. The content of all of the comments in the review are expanded.

Refresh projects

When a review is created or updated, Swarm checks to see what projects the review files are associated with and links the review to the projects it finds. If at a later date a new project is created or a new branch is added to a project, Swarm does not check to see if existing reviews are associated with new projects or project branches.

The Refresh projects option is used to check if the review files are associated with any projects created or updated after the review was last updated. If any projects are found that are not already associated with the review, the review is linked to them.

Disable notifications

When you become a review participant, by joining the review or being @mentioned in a comment or in the review's description, you receive notifications for any events associated with the review. If you find that the notifications become more of a burden than benefit and you wish to continue being a review participant, you can disable notifications:

1. Click your avatar in the reviewers area to display your reviewer options.
2. Click Disable Notifications.

Once notifications are disabled, you no longer receive notifications. However, if you are @mentioned in a subsequent review comment, you do receive a notification for that comment; regular notifications remain disabled. This approach ensures that you don't miss anything that other reviewers or the review author deems important.

Deployment status

When automated deployment has been configured for a project, the deployment success or failure is indicated in the review's heading. If your deployment program can provide a URL that provides details of the deployment, the indicator becomes linked; click the indicator to see the deployment results.

Information panel

By default, when you open the Review page for the first time, the file list panel and the information panel are hidden. Use the Show more context buttons to view the file list panel and the information panel.

For more information about the show more context buttons, see File diff panel.

Blocking Approval or Blocking Commit

Shows the total number of items that are blocking approval or commit for a review. Click to see details about the items that are blocking approval for a review. Once a review has been approved, the Blocking Approval section is not displayed.

For pre-commit reviews, if a user adds a new requirement to an approved review, then that requirement is displayed in the Blocking Commit section. For example, if a project initially has the Minimum up votes requirement set to one and this requirement is satisfied, and the review is in approved state. Now, if the Minimum up votes requirement changes to two then this requirement is displayed in the Blocking Commit section. Only when this requirement is satisfied the user can do a commit.

The Blocking Approval or Blocking Commit list consists of:

• Pending Comment Tasks: Provides a list of pending review comments that are flagged as tasks. The pending comment tasks are shown only when the disable_approve_when_tasks_open configurable is set to true in the SWARM_ROOT/data/config.php file.

  Note

  If Swarm is configured to prevent approval of reviews with open tasks and a review has open tasks, the Approve, and Approve and commit options will not be available for the review. This option is configured by an administrator. See Disable approve for reviews with open tasks.

  To approve, or approve and commit a review with open tasks, you must address the tasks first and then set them to Task Addressed, or Not a Task. See Set a task to Task addressed or Not a task for details.

  For more information about approving a review with pending tasks, see Approve a review with open tasks.

• Required Reviewers: Provides a list of all the Individual and group reviewers that are required to vote on the review. A review can not be approved or committed until the required reviewers have voted up on the review.

  A required Individual reviewer has a star badge over their avatar. A required Group reviewer either has a star badge or a star badge with a 1 over their avatar.

• Blocking Tests: Provides a list of workflow tests that have Failed or have an In progress status that is blocking approval for a review. A review can not be approved or committed until the review author fixes all the failed tests. For more information about a failed test, see Tests.

• Minimum Up votes: Provides the number of Minimum Up votes required for each project that you have access to. This includes the maximum number of Minimum Up votes required for all branches in a project blocking approval or commit for a review. For more information about Minimum up votes for a project see, General Settings tab. For more information about Minimum up votes for a project branch, see Branches tab.

  For private project, the maximum number of Minimum Up votes for all private projects and their branches that is blocking approval for a review is displayed.

• Moderator Votes: Provides a list of branch moderators that are blocking approval or commit for a review. Depending on the configuration of moderator_approval configurable in the SWARM_ROOT/data/config.php file, the branch moderator approval is required. Ensure that the branch moderator approves the review and not just up votes it.

  By default, when a review spans multiple branches that have different moderators, only one moderator from any one of the branches needs to approve the review.

  Swarm can be configured to require that one moderator from each branch must approve the review, this is a global setting. If a moderator belongs to more than one of the branches spanned by the review, their approval will count for each of the branches they belong to. For instructions on how to configure moderator behavior, see Moderator behavior when a review spans multiple branches.
