do we need sparse checkouts?

[MarcWeber]

VundleVim/Vundle.vim#252

sparse checkouts seem to allow checking out subdirectories of repositories.
The rust repository https://github.com/mozilla/rust referenced there is 35M in size (shallow clone depth=1)

This is related to runtime key

You should not use this feature.
Neobundle have implemented it, but I removed it.

Shougo/neobundle.vim#81

sparse checkouts are different from shallow clones. Sparse checkout allow to checkout a subdirectory. In the rust case it might make a big difference. Who wants to have 35M in ~/.vim if some kb would be enough? ..

[Shougo]

OK. I get it.
But sparse checkouts does not save your diskspace. I think it is not useful feature.

[MarcWeber]

thanks :)

sparse checkouts are not smaller in size (.git) - but the size of checked out files could be less. In the rust case its 35 (all) vs 5MB (.git) 40K (vim directory). So it might still be worth it.

[Shougo]

Do you want to save disk usage instead of download size?
Yes, disk usage is smaller than default checkout but download size from remote repository is same.

You made a statement: "But sparse checkouts does not save your diskspace" and the example I gave proofs your statement wrong. In the rust case you get approx 5MB instead of 35MB disk usage.

A lot of changes/fixes were made to sparse checkouts with git 1.9

So its possible both of you are right depending on what version you're using.

Yes, it is my mistake. Sorry.
