What this hour is for
How to Undo Things in Git drafts an undo. Do not reset a commit you have pushed. Do not force-push. Do not rewrite published history during the reading. If the helper offers a hard reset, write why a safer undo is enough.
Write the account, project, or repository you administer, the name of this change, and the time. A second change waits until this line has been read back.
The browser tool drafts text or reads a paste you already hold. It does not log in, it does not scan, and it does not apply.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced.
The change you can finish
Apply nothing while you are writing the note. When the lab window opens, it is one change on the account named in the ticket. Read the draft, then the account, then decide.
Rollback is the previous file, the previous plan, or the lab resource you can delete because it was only a lab.
- Write the repository and the commit you mean.
- Write whether that commit was pushed.
- Pick the undo that does not rewrite shared history.
- Do not run it during the reading.
- Stop.
Mistakes that outlive the statement
How to Undo Things in Git goes wrong in a small set of ways. The list is here so the ticket can forbid them before the window.
- A pushed commit reset.
- A force-push.
- Published history rewritten during the reading.
- The wrong repository.
Decisions to write down
One decision for How to Undo Things in Git: The commit is named. Pushed or not is written. Nothing runs during the reading. Shared history stays. And one undo is the window.
Checks before you call it done
Confirm this before you call the change done: The repository is written. Nothing was run. No force-push was used. No shared history was rewritten. And a second person can say whether it was pushed. If one of those fails, stop.
# Git undo draft. Do not run it during the reading.
# Do not reset a branch you have pushed.
# Do not force-push.
Before you leave the account
How to Undo Things in Git ends when the account in the note is the account in the ticket. If it is not, stop.
The draft stays a draft until a person has read the names in it. A generator does not log in, does not apply, and does not scan.
192.0.2.10/24, gateway 192.0.2.1, 198.51.100.0/24, 203.0.113.0/24, and 2001:db8::/32 are documentation. example.com is a documentation name. A sample password is replaced. It is not a password you keep. 10.0.0.0/16 is a sample prefix, not a network you publish unless you already use it.
prompt-for-this is a reminder that a secret is missing. It is not an access key, a token, or a password you save. An Azure secret draft may contain a sample password. Replace it. Do not file it.
One change is the window. If two things move and the result is wrong, you will not know which one did it.
If the same step fails twice, stop for the day. Restore the copy you took first.
A second person reads the account and the change aloud. If they cannot find them in the ticket, the note is not done.
