Recovering Deleted commits

• Git has two types of logs
  • log
  • ref-log: This is a permanent log but available only in .git folder
• Watch classroom video for steps

Detached Head

• Detached Head refers to a state where HEAD is pointed towards a commit rather than a branch.
• We can use this for verifying changes but never start committing changes in this case, as changes might be lost.
• Best Practice: If you want to work on the older commit,
  • checkout to that commit
  • create a branch from there git switch -c "<branch-name>"
  • Now make changes in this branch
  • if the changes are required any where else use merge or cherry-pick.

Remote

• Git remote is another repo which is ideally containing the same code as yours.
• Git Remote can be hosted
  • locally on your system for local usage (This doesnot make sense)
  • Organizations hosting git on servers owned by them (Self Hosted Git)
    • Gitolite
    • Gerrit (Hosting + Code Reviews)
    • Gitlab Self Hosted Version
    • GitHub Enterprise (SelfHosted)
  • Cloud Hosted Git Remotes
    • GitHub
    • Azure Source Repos
    • AWS Code Commit
    • Atlassian Bit Bucket
    • GitLab

Fourth Area of Git

• Remote Repo
  

Terms

• Clone: When you donot have local copy of the repo and want it on your system you perform clone
• pull: to get the latest commits into your local repo (need to dive more)
• push: to send the commits from your local repo to remote repo
• Every remote repo has a url and a name. origin is the default remote repo name.
