WSL2 环境中的 git 推送在写入对象步骤期间挂起

Question

Symptoms

I have a git workspace in WSL2 environment. The workspace is located under /mnt/c/workspace/repo where is also visible from Windows by the path C:\workspace\repo .

When I do git push from WSL2 side in the workspace, Git hang up with this message.

Enumerating objects: 39, done.
Counting objects: 100% (39/39), done.
Delta compression using up to 16 threads
Compressing objects: 100% (24/24), done.
Writing objects:  34% (9/26)

This is the other observed behavior and environment information in this context.

• I can push these files from Windows side with git for windows without any problems.
• I can push several times just after cloning files. It won't work after some of my push operations.
• This repository just contains text files. The entire repository size is less than 1MB
• I've used this environment for several months but I observed this issue just only for this repository
• This problem also happened when I copied entire folder to ~/workspace/repo where is not exposed to Windows directly.
• The remote is configured to connect with SSH and use the key under /home/<username>/.ssh

Environment information

• Linux image in WSL: 20.04.2 LTS (Focal Fossa)
• Git version: 2.25.1
• Windows version: Microsoft Windows [Version 10.0.19042.844]

$ git config --global --list
user.email=<my mail address>
user.name=<my name>
http.postbuffer=524288000

Tried workarounds

Configureing http.postBuffer

git config --global http.postBuffer 524288000

I've followed this answer in different question in stackoverflow. https://stackoverflow.com/a/26663047/3200358

This workaround won't work for me.

Windows permission change attrib -r +s

I've followed this workaround to fix some permission problem in Windows side. https://stackoverflow.com/a/63483040/3200358

attrib -r +s C:\workspace\repo

This workaround won't work for me.

Tried sudo git push

I've tried sudo git push for in case when git command can't access some lock files.

sudo GIT_SSH_COMMAND='ssh -i /home/<username>/.ssh/id_rsa' git push origin master

This workaround won't work for me.

Using https to push

The error message was changed. But this workaround won't work for me.

$ git push --set-upstream origin master -vvvv

Have you tried invoking Windows' git from WSL by using the path to the Windows git.exe ? In fact you could set up an alias in your .bashrc :

alias wgit='/mnt/c/path\ to\ git/Git/git.exe`

This way, you have a Windows executable dealing with Windows files instead of a Linux executable dealing with Windows files, though I'm a little fuzzy on how things work with the mounting.

However, I'm not sure how user-friendly this may be when entering paths.

Assuming that works, there's probably even a way to write a smart wrapper function in bash that detects which file system the repo is on and invokes the right git executable...

As an alternative, you may have more luck maintaining 2 separate repos (WSL & Windows) and then syncing via push/pulls from a server.
