stage_fixed: Couldn't stage fixed files:fork/exec C:\Program Files\Git\mingw64\bin\git.exe: The filename or extension is too long. on Windows

[ValentinGurkov]

🔧 Summary

When I have a lot of staged files that got changed and must be re-added, the list of files git add seems to be too long and results in the error:

Couldn't stage fixed files:fork/exec C:\Program Files\Git\mingw64\bin\git.exe: The filename or extension is too long.

For reference, the command I am running is:

prettier:
    glob: '*.{yml,md,gql,hbs,ts,js,json}'
    run: pnpm prettier --write {staged_files}
    stage_fixed: true

With around 452 files, the length of the git add ... command is 33852 characters long in my use case, which triggers the error,

I gradually removed some files and at around 435 files, the git add ... command was 32549 characters long in my use case and the command executed successfully.

Lefthook version

1.6.8 96d2b329e43a04c9ea3f7fb138f1606e8c33cb41

Steps to reproduce

Have a lot of staged files that get changed during hook execution and have stage_fixed: true set for the command that will execute.
With around 452 files, the length of the git add ... command is 33852 characters long in my use case, which triggers the error.

Expected results

git add during stage_fixed should work regardless of the amount of staged files.

Actual results

git add can become too long and will not be executed.

Possible Solution

I imagine like with #666 for the command length, git add can also be chunked.

However, I cannot determine whether there will be any impact when tasks are run in parallel, hopefully, somebody else knows better.

Thank you for creating this issue. I will try to figure out how to split the git add command in chunks

Please, check 1.6.9 release. I've added batching to implicit git commands. If it doesn't work, please, write back or create a new issue.
