What is a branching strategy?
A release branching strategy involves creating a branch for a potential release that includes all applicable stories.
When a team starts working on a new release, the branch is created.
For teams that need to support multiple releases and patch versions over time, a release branching strategy is required..
How do merge commits work?
Whether branches are created for testing, bug fixes, or other reasons, merging commits changes to another location. To be more specific, merging takes the contents of a source branch and integrates them with a target branch. In this process, only the target branch is changed. The source branch history remains the same.
How do you abort a merge?
On the command line, a simple “git merge –abort” will do this for you. In case you’ve made a mistake while resolving a conflict and realize this only after completing the merge, you can still easily undo it: just roll back to the commit before the merge happened with “git reset –hard ” and start over again.
Why do we fast forward merge?
A fast-forward merge can occur when there is a linear path from the current branch tip to the target branch. Instead of “actually” merging the branches, all Git has to do to integrate the histories is move (i.e., “fast forward”) the current branch tip up to the target branch tip.
Why do merge conflicts happen?
A merge conflict is an event that occurs when Git is unable to automatically resolve differences in code between two commits. … However, when there are conflicting changes on the same lines, a “merge conflict” occurs because Git doesn’t know which code to keep and which to discard.
What is a merge commit?
Recall that when you merge one branch into another, a new merge commit is created that points to both branches. In fact, a merge commit may have two or more parents as it’s possible to merge multiple branches into one at the same time. But in most cases a merge commit has exactly two parents.
What is git merge no fast forward?
The Git merge –no-ff command merges the specified branch into the command in the current branch and ensures performing a merge commit even when it is a fast-forward merge. It helps in record-keeping of all performed merge commands in the concerning git repo.
How do you avoid a merge conflict?
Below I list steps to avoid merge conflicts all together.Use A diff tool. Its always a good idea to compare branches with a diff tool this can help spot potential trouble spots before merging. … Use git fetch. … Use git rerere.
How do I continue git merge?
If the merge ever seems to be stuck, use $ git merge –continue, to nudge it along. Git should tell you if it can’t continue, and if so why not. If you feel you loused up the merge at some point, you can do $ git merge –abort, and any merging will undo and you can start over.
Are merge commits bad?
The explicit merge commits are usually perfectly fine. You usually even enforce those kind of merge commits by saying git merge –no-ff . … – But even in this case maybe a rebase might be better, as it makes the changes against the first commit more explicit and therefore less error-prone.
What does it mean to merge code?
Merging code allows multiple software developers to integrate changes into their codebase. Developers start this process by branching from a shared codeline, often referred to as a mainline. Then once work the work is completed and tested, the branch is merged back into the codebase.
What is the difference between a fast forward and recursive merge?
Note: There is nothing right or wrong of either one of the strategies but with fast forward merge you have a straight line of history and with the recursive merge, it is of multiple lines.
What is difference between Merge and rebase?
Git rebase and merge both integrate changes from one branch into another. … Git rebase moves a feature branch into a master. Git merge adds a new commit, preserving the history.
What command would we use to throw away a merge and start over?
1, you can use git reset –merge . Also, as @Michael Johnson mentions, if your git version is >= 1.7. 4, you can also use git merge –abort . As always, make sure you have no uncommitted changes before you start a merge.
Why is rebase better than merge?
The Rebase Option But, instead of using a merge commit, rebasing re-writes the project history by creating brand new commits for each commit in the original branch. The major benefit of rebasing is that you get a much cleaner project history. First, it eliminates the unnecessary merge commits required by git merge .
