bfg fails to strip objects

[marscher]

Trying to cleanup this repo https://bitbucket.org/cmb_fu/stallone.git

eg. bfg -D *.o

after re investigating the biggest blobs, the same ids are still present and are still referenced by something, because git gc --aggressive --prune=now does not remove those blobs.

btw:

  bfg -B 1 --no-blob-protection

tries to remove the same object over and over, if executed multiple times.

Are you sure that you've followed the BFG usage instructions? In particular, this line seems to be missing in the report you made earlier to the Git mailing list:

git reflog expire --expire=now --all

The Git reflog retains references to 'old' branch positions, so unless you clear the reflog, git gc can't dispose of the referenced junk.

Thanks for providing a link to your repo - I ran the BFG on a copy locally, and git gc seemed to work fine:

$ du -h objects/
15M objects/pack
4.0K    objects/info
15M objects/
$ java -jar bfg-1.11.8.jar -D *.o
...
In total, 216 object ids were changed - a record of these will be written to:

    /tmp/tmp.Yun2EygWIA.bfg-report/2014-12-08/17-14-14/object-id-map.old-new.txt

BFG run is complete!
$ reflog expire --expire=now --all
$ git gc --prune=now --aggressive

Compressing objects: 100% (3670/3670), done.
Writing objects: 100% (3968/3968), done.
Total 3968 (delta 2726), reused 985 (delta 0)
$ du -h objects/
11M objects/pack
8.0K    objects/info
11M objects/

As you can see, the pack size has been reduced by 4MB.

I've pushed the results up to https://github.com/bfg-repo-cleaner-demos/stallone - no problems (or *.o files) that I could see.

doh :) I just forgot this step. Thanks
