Summary

Bitbucket Data Center and Server versions 5.1.0 and later provide the ability to delete pull requests. This feature is enabled by default 

Users who can delete pull requests

By default, the following users can delete pull requests:

• Pull request authors - authors can delete their own pull requests
• Repository administrators - repository admins can delete anyone else's pull request within the repository they have admin access to

In case you want to disable the feature to delete pull requests, or change which permission is required to delete pull requests, please follow the steps below:

Solution

The configuration settings listed below are set in the <BITBUCKET-HOME>/shared/bitbucket.properties file. See Bitbucket config properties for more information.

Disable the feature to delete pull requests

To disable the feature to delete pull requests, add the following property:

feature.pull.request.deletion=false 

Note that disabling this feature will prevent pull request deletion globally.

Change which permission is required to delete pull requests

To change which permission is required to delete the pull requests, set the following property:

# Determines which users can delete pull requests.
# Valid values are:
#     - `AUTHOR` pull request authors and repository admins can delete pull requests
#     - `REPO_ADMIN` repository admins can delete pull requests
pullrequest.deletion.role=REPO_ADMIN

• If the property is set to AUTHOR, pull request authors and repository admins can delete pull requests. This is the default setting.
• If the property is set to REPO_ADMIN, only repository admins can delete pull requests. Pull request authors will not be able to delete their pull requests.
  
  Note: Please make sure that users to whom you would like to restrict from deleting the pull requests, do not have admin or system admin permissions globally under the Administration → Global Permissions section otherwise they should be able to delete the pull request.
