Git Pull执行完全卡住（Git 2.13.5/Apple Git-94）求助

Hey there, let’s work through this stuck git pull issue you’re facing. Older Apple-distributed Git versions like 2.13.5 (Git-94) can have quirky behavior with connections or local state, so here’s a step-by-step approach to fix it:

1. First, terminate the stuck Git process #

If git pull is frozen, hit Ctrl+C to kill the running command. If that doesn’t work, open a new terminal window and run:

ps aux | grep git

Look for the git pull or related Git processes, note their PID numbers, then terminate them with:

kill <PID_NUMBER>

2. Diagnose the root cause with verbose fetch #

git pull combines git fetch and git merge, so isolating the fetch step can tell you if the issue is network-related or a merge problem. Run:

git fetch --verbose

• If this hangs too: The problem is likely a network connection issue with your remote repository.
• If this completes successfully: The issue is with the merge step, which we’ll address later.

3. Fix network connection issues #

If git fetch hangs, try these checks:

• Test SSH connectivity (if you use SSH for repo access):

  ssh -T git@<YOUR_REPO_HOST>  # e.g., git@github.com
  

  You should get a friendly confirmation message if the connection works. If not, check your SSH keys or firewall settings.
• Check for proxy interference: Older Git versions can misbehave with proxies. Run these commands to see if a proxy is configured:

  git config --global --get http.proxy
  git config --global --get https.proxy
  

  If output returns a proxy URL, unset them temporarily:

  git config --global --unset http.proxy
  git config --global --unset https.proxy
  

• Test HTTPS connectivity (if using HTTPS):

  curl -v https://<YOUR_REPO_URL>
  

  This will show you if the remote server is reachable and if there are SSL or redirect issues.

4. Resolve merge-related hangs #

If git fetch works but git pull still hangs, the issue is likely with the merge step:

• Run merge manually: Instead of using git pull, execute the two steps separately:

  git fetch origin
  git merge origin/<YOUR_BRANCH_NAME>  # e.g., origin/main
  

  If there are merge conflicts, Git will prompt you to resolve them instead of hanging.
• Check for stale lock files: Sometimes a previous failed operation leaves a lock file. Delete it with:

  rm -f .git/index.lock
  

5. Clean up local Git state #

Older Git versions can accumulate stale objects that cause hangs. Run this to clean up:

git gc --prune=now

This removes unreachable objects, optimizes the repository, and clears cached connections.

6. Consider upgrading Git (optional but recommended) #

Apple’s bundled Git 2.13.5 is quite outdated (released in 2017). Many connectivity and stability issues have been fixed in newer versions. If you can, install a newer Git via Homebrew:

brew install git

Then verify the new version is active:

git --version

Start with the earliest steps and work your way down—most stuck git pull issues in this version are either network-related or stale local state problems.
