+### Intermittently pipelines fail by `fatal: reference is not a tree:` error

+## Persistent pipeline refs
+
+> [Introduced](https://gitlab.com/gitlab-org/gitlab/merge_requests/17043) in GitLab 12.4.
+
+Previously, you'd have encountered unexpected pipeline failures when you force-pushed
+a branch to its remote repository. To illustrate the problem, suppose you've had the current workflow:
+
+1. A user creates a feature branch named `example` and pushes it to a remote repository.
+1. A new pipeline starts running on the `example` branch.
+1. A user rebases the `example` branch on the latest `master` branch and force-pushes it to its remote repository.
+1. A new pipeline starts running on the `example` branch again, however,
+   the previous pipeline (2) fails because of `fatal: reference is not a tree:` error.
+
+This is because the previous pipeline cannot find a checkout-SHA (which associated with the pipeline record)
+from the `example` branch that the commit history has already been overwritten by the force-push.
+Similarly, [Pipelines for merged results](merge_request_pipelines/pipelines_for_merged_results/index.md)
+might have failed intermittently due to [the same reason](merge_request_pipelines/pipelines_for_merged_results/index.md#intermittently-pipelines-fail-by-fatal-reference-is-not-a-tree-error).
+
+As of GitLab 12.4, we've improved this behavior by persisting pipeline refs exclusively.
+To illustrate its life cycle:
+
+1. A pipeline is created on a feature branch named `example`.
+1. A persistent pipeline ref is created at `refs/pipelines/<pipeline-id>`,
+   which retains the checkout-SHA of the associated pipeline record.
+   This persistent ref stays intact during the pipeline execution,
+   even if the commit history of the `example` branch has been overwritten by force-push.
+1. GitLab Runner fetches the persistent pipeline ref and gets source code from the checkout-SHA.
+1. When the pipeline finished, its persistent ref is cleaned up in a background process.
+
+NOTE: **NOTE**: At this moment, this feature is off dy default and can be manually enabled
+by enabling `depend_on_persistent_pipeline_ref` feature flag, however, we'd remove this
+feature flag and make it enabled by deafult by the day we release 12.4 _if we don't find any issues_.
+If you'd be interested in manually turning on this behavior, please ask the administrator
+to execute the following commands in rails console.
+
+```shell
+> sudo gitlab-rails console                                        # Login to Rails console of GitLab instance.
+> project = Project.find_by_full_path('namespace/project-name')    # Get the project instance.
+> Feature.enable(:depend_on_persistent_pipeline_ref, project)      # Enable the feature flag.
