CVE-2022-3037 Use After Free in GitHub repository vim/vim prior to 9.0.0322.
After using the file scm command in a repository, you may encounter error message “cannot open remote connection” when attempting to edit the file.
This is because you are editing the file in the remote repository and not the local one. To fix this, run the following command in your local repository after creating it:
git remote add origin your_repository_url>
After this, you can edit the file in the remote repository and commit it.
If you are using GitHub Enterprise, you can do the same thing through the GitHub Support Portal. There, you can create a GitHub project and add the remote repository as a remote.
Git Workflow
A git workflow is a series of commands that you use to manage your code in the repository. In general, a git workflow consists of two parts: initializing and committing. Git workflows are an alternative to using version control software such as Subversion, which manages version control through files with timestamps.
To initialize a new repository, run the following command:
git init
This creates an empty history and staging areas for future commits. You can then add one or more files to the staging area by running the following command:
git add file_name
This will keep track of all changes and commit them when you are done editing them. To commit your changes, run the following command:
git commit -m "message" .
The message can be anything you want it to be; for example, "added a bunch of new features."
How to fix “cannot open remote connection” error in Git
A problem may occur when you try to edit a file in a remote repository and run the scm command. The error is displayed as “cannot open remote connection”. This can happen if you are editing the file on the project's master branch, but trying to commit it back to the project's main branch, or if you are trying to commit a local file into the project's master branch.
To fix this problem, first make sure that your repository is set up correctly. If it is not, then follow these steps:
1. Login into your GitHub Enterprise instance using SSH.
2. After logging in, run this command: git config --global core.editor "vi"
3. Make sure that Git is configured properly for your GitHub Enterprise instance by running this command in your local repository after creating it: git config --global core.editor vi
Run these commands in the local repository git remote add origin your_repository_url>
git push -u origin master
Check if there is a known issue with Git and the file
git status
If there is a known issue with Git and the file, then you will get a message like this:
- fatal: This repository appears to have moved or changed location permanently. Please contact the original Git project for help.
