optimizing the space occupied for .repo/project-objects

[Dmitry]

Hi,

I'm wondering is it possible to save some space occupied by .repo/project-objects?

Is it possible to link these repositories to some local "mirror"?

There is a mirror option in repo tool, but it seems just copies .repo/project-objects from a local mirror.

I would just link this folder to a local "mirror" but I seems to be very careful to avoid mixing it for AOSP and Cyanogen manifests. Is it possible to place repos in .repo/project-objects under corresponding remote ("aosp" or "github", for example)?

I think a simplest way is to add a --share-objects option, and make make .repo/project-objects a symbol link to ~/.project-objects

If a user init many manifest projects, it will save a lot in git related transfer and local storage.

And because in project-objects, we don't store any reference, so there is no chance to conflict even we mix aosp and github git because of the paths are same.

I make a local prototype of repo, after try I found that the different projects share project-objects directory but don't share pack files.

For example, I create 3 repo projects contain frameworks/base, and I got one more pack file for each project:

```

zhangclb@zhangclb2:~/.project-objects/platform/frameworks/base.git/objects/pack$ ll

```

Why does this happen?

Prototype I made: https://github.com/zhangchunlin/git-repo/commit/0c16efd203f0b768c103362386f9ae67730bb78f

Still have no idea why the gc packfile cannot be reused.
