How to build your own Gitlab library

To add a subtree to a Git repository, first add the remote repository and get its history, then merge it into a subdirectory using the gitmerge and gitread-tree commands. The steps are as follows: 1. Use the gitremoteadd-f command to add a remote repository; 2. Run gitmerge-srecursive-no-commit to get branch content; 3. Use gitread-tree--prefix= to specify the directory to merge the project as a subtree; 4. Submit changes to complete the addition; 5. When updating, gitfetch first and repeat the merging and steps to submit the update. This method keeps the external project history complete and easy to maintain.

To force delete an unmerged Git branch, use the gitbranch-D command. This command ignores the merge status of the branch and deletes it directly. It is suitable for useless branches after testing, abandoned feature branches, or local old branches that need to be recreated from remotely. However, it should be noted that the submission record will still exist locally after deletion and will eventually be cleaned up by the garbage collection mechanism; after mistaken deletion, it can be restored through gitreflog, but the window period is short. Therefore, before execution, be sure to confirm that the branch is useless, uncooperated and the name is correct to avoid data loss.

Yes, you can use a command to create and switch to a new Git branch, the specific method is as follows: 1. Use gitswitch-c: This is a more modern and clear way, for example, gitswitch-cnew-feature will create and switch to a branch named new-feature immediately; 2. Use gitcheckout-b: This is an older but commonly used method, for example, gitcheckout-bnew-feature has the same effect as the former. Note: gitswitch was introduced in Git2.23, and old versions need to use gitcheckout. You can specify the branch based on other branches, such as gitswitch-cnew-

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 method to set the Git username and mailbox is to use the gitconfig--globaluser.name and gitconfig--globaluser.email commands to configure the identity information globally. The specific steps are as follows: 1. Set the username: Run gitconfig--globaluser.name "YourName"; 2. Configure the mailbox: Run gitconfig--globaluser.email "your.email@example.com"; 3. Verify the settings: pass gitconfiguser.name and gitco
