cloning only the default branch and with a depth of 1 speeds up the clone time greatly

I will try to take a look at this sometime but any mistake here can brick Krew installations forever, and our commit history is not particularly bloated so it's not top priority right now. Let me know if there's a particular reason you're pushing for it.

[slimm609]

thanks @ahmetb. With larger private repos for plugins, it can take a very long time to install or update because it downloads the entire history of the repo just to install and all branch references just to install from the main branch. This changes to only download the most recent commit (no history) and only the repo's main branch instead of the main branch plus all additional branches.

Sorry for the delay here. I have a follow up question: doesn't the subsequent "git fetch origin && git reset -hard @{upstream}" command re-download the repository anyway?

If that's the case, I don't think this optimization is worth doing (and may end up being worse) for long-term installations that install/update plugins on the same machine over time.

git reset --hard @{upstream} will just reset but git fetch -v can be updated to git fetch -v origin HEAD to only apply to the that branch
