How reduce size in Bitbucket repo after clean it-CodePudding

I have a repository in Bitbucket that has ~160MB used, I deleted all branches. The repo is totally clear it continues saying that i have 160 MB used.

How can i real delete all the files in my repo. I dont want to create a new repo.

As adittion. If i add some files , for example "file.mp3" to the repo, then i delete it, it increase the Repo Size and i cannot reduce it again. I tried some post like this Atlassian Help.

Best,

EDIT: Im trying to use BFG. When i made a "bfg --strip-blobs-bigger-than 1M" i got:

These are your protected commits, and so their contents will NOT be altered:

In total, 9 object ids were changed.

Once you add the object to the object DB, it will stay there for at least a while if the object is not pointed by something like a current branch/tag. Even if the object is not pointed by a branch/tag, it can still be held for a while by the reflog which can take a little bit to allow a revision to be cleared up. Git does garbage-collection every so often... and you can force to run it with git gc. Check its options and have fun with it.

CodePudding user response：

The thing is git stores hashes perpetually, so you have to work a bit harder to remove stuff. By deleting branches, you're really just deleting references to patches stored in the repository.

I recommend you try using bfg. It is very fast and very simple to use.

git clone --mirror git://example.com/some-big-repo.git
java -jar bfg.jar --strip-blobs-bigger-than 100M some-big-repo.git
cd some-big-repo.git
git reflog expire --expire=now --all && git gc --prune=now --aggressive
git push --force

These settings will need to change to suit you needs, but this will actually rewrite the contents of the blobs in the repository.

Verification

To verify these steps, I did the following:

mkdir bfg-test
cd bfg-test
echo "Test bfg cleanup in bitbucket." > README.md
git init
git remote add origin [email protected]:theherk/bfg-test.git
git add README.md
git commit -m "Initial commit."
git push origin main
# size in bitbucket.org: 57.94 KB
dd if=/dev/urandom bs=1048577 count=1 | base64 > garbage
git add garbage
git checkout -b garbage-branch
git commit -m "Add garbage file."
git push origin garbage-branch
# size in bitbucket.org: 1.12 MB
git checkout main
git branch -D garbage-branch
git push origin -d garbage-branch
# size in bitbucket.org: 1.12 MB
cd ..
git clone --mirror [email protected]:theherk/bfg-test.git
java -jar ~/bin/bfg.jar --strip-blobs-bigger-than 1K bfg-test.git

At this point, I found no large blobs. If it were there, it would have been stripped. So I checked the size of the repo mirror. 88 KB; as opposed to 1.12 MB reported by bitbucket.org. Turns out, bitbucket did prune the file and the repository actually is smaller, their interface just lies and reports usage including dangling files that will be cleaned up at a later date.

Bottom line, if your clone is smaller, then don't trust the information in your repository settings.
