问题
I've a repo on https://bitbucket.org/
Few days ago by a mistake big number of image files were pushed in the repo. then files were deleted via another push. after that repo worked ok, but today when i try to pull from the repo:
$ git pull
Password for 'https://repo@bitbucket.org':
warning: no common commits
remote: Counting objects: 4635, done.
remote: Compressing objects: 100% (1710/1710), done.
fatal: Out of memory, malloc failed (tried to allocate 4266852665 bytes)
fatal: index-pack failed
I've tried:
1) git config --global pack.windowMemory 1024m
2)
$ git count-objects -v
count: 9
size: 48
in-pack: 4504
packs: 1
size-pack: 106822
prune-packable: 0
garbage: 0
No luck there, not sure what actions should i take next...
The size of the repo should be around 10-20m of code. what actions should i take next?
UPDATE 1
i executed these commands:
$ git filter-branch --index-filter 'git rm --cached --ignore-unmatch public/images/*' HEAD
Rewrite a1c9fb8324a2d261aa745fc176ce2846d7a2bfd7 (288/288)

and
$ git push --force --all

To https://repo@bitbucket.org/repo.git
+ 203e824...ed003ce demo -> demo (forced update)
+ d59fd1b...a1c9fb8 master -> master (forced update)
Pull then works ok:
$ git pull
Already up-to-date.
But when i try to clone repo i get
~/www/clone$ git clone git@bitbucket.org:repo.git
Cloning into 'clone'...
remote: Counting objects: 5319, done.
remote: Compressing objects: 100% (1971/1971), done.
fatal: Out of memory, malloc failed (tried to allocate 4266852665 bytes)
fatal: index-pack failed
UPDATE 2
Sadly enough i didn't find all of the large files. some are still left. So i asked support to kill all the logs of the repo
UPDATE 3
In the end i had to kill old & create new repo.
回答1:
If you are the only one using this repo, you can follow the git filter-branch option described in "How to purge a huge file from commits history in Git?"
The simpler option is cloning the repo to an old commit, and force push it, as described in "git-filter-branch to delete large file".
Either one would force any collaborator to reset his/her own local repo to the new state you are publishing. Again, if you are the only collaborator, it isn't an issue.

In my case it was something as simple as trying to pull a big repo in a 1GB RAM box without swap.
I followed this tutorial https://www.digitalocean.com/community/tutorials/how-to-add-swap-on-ubuntu-14-04 to create some swap space on the server and worked.
Their "faster" way:
sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
You can make these changes permanent by adding to /etc/fstab:
/swapfile none swap sw 0 0
They recommend adding to /etc/sysctl.conf:
vm.swappiness=10
vm.vfs_cache_pressure = 50

Even if the big image files have been deleted after having being pushed, they do stay in the git history.
I would suggest to forcibly remove them from the git history (I think that is possible, but it involves a delicate procedure that I don't know).
Alternatively, pull the repository before the mistakenly added files, patch the repository to make the relevant small patches, clone that, and use that (perhaps with a dump/restore) as your master git.
I don't know well the details, but I did read it could be possible

I recently encountered this issue with one of my repositories. Similar error, hinting at a large file hidden in the repo somewhere.
Cloning into 'test_framework'...
remote: Counting objects: 11889, done.
remote: Compressing objects: 100% (5991/5991), done.
Receiving objects: 66% (7847/11889), 3.22 MiB | 43 KiB/sremote: fatal: Out of memory, malloc failed (tried to allocate 893191377 bytes)
remote: aborting due to possible repository corruption on the remote side.
fatal: early EOFs: 66% (7933/11889), 3.24 MiB
fatal: index-pack failed
To get around this I temporarily created a large swap drive (in excess of the 893191377 bytes the server was asking for) following Method 2 from here: http://www.thegeekstuff.com/2010/08/how-to-add-swap-space/
This allowed me to successfully clone and then remove the culprit (someone had checked in an sql dumpfile). You can use:
git filter-branch --tree-filter 'rm -rf dumpfile.sql' HEAD
to remove the file from the git repo.
