Git’s graph model
A graph is a way to model connections and consists of edges and nodes.
Types of graphs:
- Directed Graph: Nodes are connected in a particular direction.
2. Acyclic Graph: Graphs having no cycles.
3. Directed Acyclic Graph: Nodes are connected in a particular direction with no cycles within the graph.
Branches
A branch occurs if a commit has more than one child.
In the above graph, we can see that there are 2 new branches 1 & 2 carrying new commits.
Types of Branches :
- Topic branches: A feature, bug fix, configuration change.
- Long-lived branches: master branch, develop are some examples of long-lived branches.
Creating branches:
Command:
git branch <branch_name>To change the branch
git checkout <branch_name>A shortcut way to create as well as change the branch is using the “-b” flag
git checkout -b <branch_name>
# -b flag creates and chekouts the branchDeleting branches
Command
git branch -d <branch_name>
#-d flag is used to delete a branchgit branch -D <branch_name>
#This will delete the branch but the commit associated to that branch will not be deleted. That commit is stored as garbadge value.
This is called as dangling.
