![]() ![]() It also means the main branch will never contain broken code, which is a huge advantage for continuous integration environments.Įncapsulating feature development also makes it possible to leverage pull requests, which are a way to initiate discussions around a branch. This encapsulation makes it easy for multiple developers to work on a particular feature without disturbing the main codebase. In the unlikely case of the above algorithm resulting in equality of 2 branch names, a simple string comparison is performed on the whole branch name.The core idea behind the Feature Branch Workflow is that all feature development should take place in a dedicated branch instead of the main branch.If both tokens are non-numeric, a simple ASCII comparison is used.When comparing a numeric token with an ASCII token, the numeric is ranked higher (that is, it is considered as being a newer version). Branches are ordered by number, if a given token is numeric.Matching means that every token before the first numeric token must be equal to the corresponding tokens of the target branch's name. Only branches matching the name of the pull request target are added into the merge path.Branch names are split into tokens using any of these characters: underscore '_', hyphen '-', plus '+', or period '.'.the target of the pull request for the merge). Branches are selected and ordered on the basis of the name of the branch that started the cascade (i.e.Ordering is based on semantic versioning in the naming pattern for branches.īitbucket uses the following ordering algorithm to determine the branches in the merge chain: To cascade changes to newer release branches, Bitbucket must be able to determine the ordering of branches. In the Cascading merge section, select On and then select Save.To enable cascading merge for an individual repository (requires repository admin permission): Learn more about how project admins can restrict changes to repository settings If the project admin hasn't restricted repository-level changes, you can customize settings for individual repositories. In the Cascading merge section, select On, and then select Save.Ĭonfigure cascading merge for a single repository.To enable cascading merge for all repositories in a project (requires project admin permission) : Configure cascading merge for all repositories in a project Repository admins can either inherit the project-level branch settings or override the settings at the repository level. This means that any merging is blocked because of the open pull request downstream.īy default, branch settings (including cascading merge settings) from the project level are inherited by the repositories. Blocked from merging until the pull request that was opened for the merge conflict is resolved. ![]() This means that the next time a merge is attempted, there will be a warning stating that there is an open pull request downstream. Allowed to merge but only to the pull request opened for the merge conflict.You can choose from these two options on how pull requests from the upstream merge conflict should behave: Conflicts will need to be resolved and there are chances you may not even see that there was a pull request created. The pull request is assigned to you because you attempted to perform the merge. Bitbucket then opens a pull request from R3 to R4. If you merge to R1, then Bitbucket merges to R2 and R3, but cannot merge to R4 because of the conflict. With automatic merging on, let's then say that there is a merge failure with R4. I.e., If you merge a pull request to R2, it will automatically merge R3 and R4 until you get to the development branch. For example, if you have multiple release branches, R1, R2, R3, and R4, they can all automatically merge into one another with automatic merging enabled. ![]()
