git filter-repo is not deleting all records from git log

54 views Asked by At

I have an example git which contains 2 folders, t1 and t2, with 3 empty files each.

The log from creating the git is this:

            new file:   t2/t2.txt

The task is to delete folder t1 and all its content from git and it's history, including the log. Ie. the git should look like as if t1 and its content never existed. For that I am using

git filter-repo --invert-paths --path t1

Afterwards, the folder t1 is gone, but the log looks like this:

            new file:   t2/t2.txt

It appears as if only the committes are erased where only folder t1 is was affected.

What I would like to see is that also all other commits are cleaned. Is this possible??

Thanks
