Applying and testing a patch in Talend Studio

About this task

Before applying the patch on a Talend Studio production branch, Talend recommends to first create and use a test branch for the patch testing.
Information noteNote: The following best practices only apply to projects managed with Talend Administration Center.
In the following steps:
  • Studio_1 refers to the current Talend Studio instance used for production.
  • Studio_2 refers to the Talend Studio instance used for testing the patch.

Apache Subversion is deprecated from 7.3.1 R2021-08 release onwards

Procedure

  1. Open Talend Administration Center and select the project you want to test the patch on.
  2. Create a new branch named patch_testing (or any other name) based on the production branch via Talend Administration Center. For more information on how to use Talend Administration Center to create a Git or SVN branch, see Create a Git or SVN branch. You can also create the patch_testing branch without Talend Administration Center using Git/SVN.
  3. Install another Talend Studio instance (Studio_2) to test the patch.
  4. Apply the patch in the Studio_2 instance manually and launch it. For more information, see Applying a patch to Talend Studio / Talend CommandLine.
  5. Select the project in the patch_testing branch.
    Information noteNote: If the project has reference projects, you need to log into the main project with the first Talend Studio instance (Studio_1) to change the project reference to your test branch (in this example, patch_testing) to make sure all the projects you test are on the patch_testing branch. Then, use the Studio_2 to migrate the reference projects before the main project.
  6. A warning window appears, click OK to migrate the project to the new patch version.

Results

You applied the patch to Studio_2 and migrated your projects in the patch_testing branch. You can now test the patch.

If the test is successful, you can apply the patch to the Talend Studio instance used for production (Studio_1) and migrate other production branches via Talend Administration Center, see Applying a patch to Talend Studio via Talend Administration Center.

If the test is not successful, please contact Talend Support.
