Clone arguments --depth 1 not working with lg.callMain(['clone', url, dir, '--depth', '1'])

Currently trying to experiment the performance of wasm-git for not-so-small Git repositories, but using --depth 1 on a clone call doesn't seem to have any effect. Any idea what could be happening?

What I did was I modified the githttpserver to not add an Authorization header to HTTP requests and used Isomorphic Git's CORS proxy to bypass CORS restrictions to GitHub. So from my localhost, I try to download any fairly-sized GitHub repository, and it takes forever, even with --depth 1.

Let me know if I can help fixing this!

Looks like I had some reading to do before opening this issue :)

Just found that lg.callMain is actually deferring to examples/lg2.c's main, which then calls libgit2's clone function. Also, shallow clones are not supported by libgit2 (as per libgit2/libgit2#3058), so closing this issue.

sorry for not seeing this before now, but thanks for going into the depths of this. I wasn't aware of the missing support for shallow clones myself.

Shallow clone is now supported in libgit2 =)

And btw, is there any solution to clone with --single-branch option?

wasm-git is now up to date with the latest libgit2

Where I can see api docs? I tried to use lg.callMain(["clone", url, dir, "--depth", "1"]), and it looks like it's not working.

at this point wasm-git expose the examples from libgit2, and then you need to modify this file here: https://github.com/libgit2/libgit2/blob/main/examples/clone.c so that it can accept the depth argument ( or just set the clone_opts.fetch_opts.depth property directly to what you want ).

however there's also a new cli in libgit2 that I would like to add support for and it seems it also does handle depth:

https://github.com/libgit2/libgit2/blob/main/src/cli/cmd_clone.c

CLI support is on my todo list.
