Hi,

thank you for the answer.

I understand that the core of git is to make people work together when
writing code.
To get a tree of the source files is not directly part of that, but
pure informational. That is also the intent of my fuse fs: provide the
user information about the source files.

Now I have a working ssh connection to the server, and open a channel
for running the upload-pack on the server using the exec channel
request:

https://datatracker.ietf.org/doc/html/rfc4254#section-6.5

So in my program I do not have to do something like:

ssh -x git@server "git-upload-pack 'simplegit-progit.git'"

It is only the sending of an exec message with the right command.
Via the SSH_MSG_CHANNEL_DATA message the server will return the
output. In my program I have to write a parser to get the
tree/direntries.

Now you suggest the git clone --depth 1 --filter=blob:none
--single-branch -b $branch
command. How does that look when writing it in lowlevel git messages
as described in

https://git-scm.com/book/en/v2/Git-Internals-Transfer-Protocols

?
I'm programming at this low level, so I have to write the messages to
send to the server myself.

And you mention the api github has for a git tree object. But git2 has
already the git_tree object?
