git filter branch - Remove contents of a commit from a git repo after its already been git -rm'ed and pushed -

-

so had user add , remove large directory of files in workspace 2 distinct commits. pushed changes central repo , end user looks noop. problem our central repo has jumped 50x in size because of this. have tried several things filter branch , not working.

so folder added @ root level. name of .core

i have tried following filter-branch based on links:

http://www.somethingorothersoft.com/2009/09/08/the-definitive-step-by-step-guide-on-how-to-delete-a-directory-permanently-from-git-on-widnows-for-dumbasses-like-myself/

http://dound.com/2009/04/git-forever-remove-files-or-folders-from-history/

remove directory permanently git

the final commands have tried looks this:

git filter-branch -f --index-filter "git rm -rf --cached --ignore-unmatch .core" --prune-empty --tag-name-filter cat -- --all rm -rf .git/refs/original rm -rf .git/refs/logs git reflog expire --expire=now --all && git gc --prune=now --aggressive

the resulting output says ref unchanged. have tried changing reference of .core various variations such ./.core, *.core/*, ..... nothing getting removed.

thanks.

use the bfg, simpler, faster alternative git-filter-branch, designed removing unwanted files git history.

carefully follow bfg's usage instructions - core part this:

$ java -jar bfg.jar  --delete-folders .core  my-repo.git

any folder named .core (that isn't in latest commit) removed git repository's history. can use git gc clean away dead data:

$ git reflog expire --expire=now --all && git gc --prune=now --aggressive

the bfg typically @ least 10-720x faster running git-filter-branch, , easier use.

full disclosure: i'm author of bfg repo-cleaner.
