How to delete a branch in git

Use gitmerge --no-ff to force Git to create merge commits, even if you can fast forward. 1. Use the --no-ff parameter to preserve branch history and clarify the source of change; 2. This method is particularly useful during code review or auditing, and is often used in strict branch strategies such as GitFlow; 3. This operation can be automated by configuring alias or scripts, such as gitconfig--globalalias.merge-noff'!gitmerge-no-ff', thereby simplifying the process.

The reason for setting up the upstream branch is to let Git know the default pull and push targets, simplifying operations and avoiding confusion. When you create a new local branch, Git will not automatically associate the remote branch, resulting in manually specifying the remote branch every time you execute gitpull or gitpush; by running gitpush-uoriginfeature-branch, you can set up the upstream branch on the first push, where the -u parameter makes Git remember the connection, and then pull or push can be performed without additional parameters; if it has been pushed but has not set up the upstream or needs to change, you can use the gitbranch--set-upstream-to=origin/feature-branch command to adjust it.

The steps to add submodules to the Git repository are as follows: 1. Use the gitsubmoduleadd[URL][Path] command to add submodules, which will clone the repository and create the .gitmodules file; 2. When cloning the repository of the submodule, you need to run gitsubmoduleupdate-init-recursive to initialize and update the submodule; 3. You can specify the trace of a specific branch through the -b option, and use gitsubmoduleupdate--remote to update to the latest commit of the branch. In addition, submodules have independent .git directories. Modifications need to be submitted within the submodule. Deletion needs to be initially

The key to using Git on a team is to follow basic practices and maintain good communication. 1. Determine the shared repository and branch policies, the main branch is used to stabilize the code, and the feature branch is used to develop new functions or fix problems; 2. Communicate before merging or pushing changes, pulling the latest code first to avoid conflicts; 3. Use pull requests (PR) and code review process to ensure that all changes have been discussed and confirmed; 4. Actively handle merge conflicts, pulling updates regularly, and carefully resolving and testing when conflicts are encountered. These practices help to improve teamwork efficiency and reduce errors.

To revoke a commit that has been pushed to a repository but keeps history, use gitrevert to create a new commit to reverse the changes to the specified commit. 1. Use gitlog--oneline to find the hash value of the target commit; 2. Execute gitrevert or such as gitrevertHEAD~2 to revoke a specific commit; 3. If there is a conflict, manually resolve it and continue with gitrevert--continue, or abort; 4. Submission information can be edited and confirmed; 5. For merged commits, the -m1 parameter needs to be added. This method is safe for shared branches and avoids problems caused by rewriting history.

To delete stashes that are no longer needed in Git, use the command to accurately delete specific stashes or clear all. 1. Delete a specific stash: Delete the stash of the specified index through gitstashdropstash@{n}, such as gitstashdropstash@{1} to delete the second entry; 2. Clear all stash: Use gitstashclear to delete all stash at once, but this operation is irreversible; 3. Recover the wrong stash: If you just deleted, try to use gitfsck--unreachable to find danglingcommit and create branch recovery, but it is only valid before the object is garbage collected. Be sure to operate
