I was working on branch A when suddenly everything crashed and stopped working. I thought I might broken something in my code so I committed my changes and created new branche B from branch A to keep it as a backup. then I revert branch A to the last working commit, and start trying to fix any possible bugs. I realised later that the server had a problem not my code. So I deleted branch A and contenue working in branch B.
I did this because I'm no git expert so I sorted things out with my little knowledge. I believe there should be much easer, cleverer and more appropriate ways to solve such a problem than my "very stupid" way :)
Any suggestion?
You could have reset A branch to the last working commit again,
git checkout branch_A
git reset --hard last_working_commit_id
merged the "unbroken" code from B back to A branch,
git merge branch_B
then delete B branch and continue working with A branch.
git branch -d branch_B
