Example 19 with RepositoryApi

use of org.gitlab4j.api.RepositoryApi in project legend-sdlc by finos.

the class GitLabWorkspaceApi method attemptToSquashAndRebaseWorkspace.

/**
 * This method is called when we failed to rebase the workspace branch on top of master branch. This implies that either
 * the whole change is causing a merge conflict or one of the intermediate commits have conflicts with the change in master branch
 * <p>
 * To handle the latter case, this method will squash all commits on the workspace branch and attempt rebase again.
 * If this fails, it implies that rebase fails because of merge conflicts, which means we have to enter conflict resolution route.
 * <p>
 * NOTE: based on the nature of this method, we have an optimization here where we check for the number of commits on the current
 * branch, if it is less than 2 (not counting the base), it means no squashing is needed and we can just immediately tell that there
 * is merge conflict and the workspace update should enter conflict resolution route
 * <p>
 * So following is the summary of this method:
 * 1. Create a temp branch to do the squashing on that branch
 * 3. Attempt to rebase the temp branch on master:
 * - If succeeded: re-create current workspace branch on top of the temp branch
 * - If failed -> implies conflict resolution is needed
 *
 * @return a workspace update report that might have status as UPDATED or CONFLICT.
