Hotpatch refers to the process of fixing online problems by modifying code instead of releasing a version. The hotpatch management page is the background for fixing urgent client problems. On this page, you can create release tasks and perform multi-dimensional hotpatch configuration.

About this task

On the hotpatch management page, you need to complete the following operations:

  1. Add a hotpatch: Add the hotpactch package on the mPaaS console.
  2. Release a hotpatch package: According to best practices, you need to complete three release tasks for a hotpatch package: whitelist gray release, time-window gray release, and official release.
    Note: If a code defect occurs in the process of releasing a hotpatch package, you can roll back the release.
  3. Manage a release task: Involves modifying, pausing, and ending a release task.

A hotpatch package can be either an Android or an iOS hotpatch package. For Android clients, only one hotpatch package is allowed for one version. If two problems are found in a version of the Android client, you should merge the hotpatch packages for the two problems into one, and then upload the merged hotpatch package.

Add a hotpatch

  1. Log in to the mPaaS console, and choose Mobile Delivery Service > Hotpatch management in the left-side navigation pane. The hotpatch release list is displayed.

  2. Click Add hotpatch resource, and complete hotpatch configuration in the Add hotpatch resource dialog box.

    Note: For Android platforms, Target version in this dialog box refers to the version number of the Portal package.

    Note:

    • If a hotpatch package has never been released, it does not have any release tasks and remains in “To be released” state. A hotpatch resource can have only one valid release task at a time.
    • If a hotpatch package has been released, it has release tasks and remains in the release status defined in the latest release task.
