Cool!  I better look at the spec for that first.

*looks at the previous patch*

Oh, there is no documented spec. :/  I'll muddle through this instead,
then.

This is the 'list' command, right?  Since we expect the client to run
'stateless-connect' instead, can we make it error out?

Can this have a comment describing what it is/does?  It's not obvious
to me at first glance.

It doesn't have to go in a lot of detail since this is an internal
implementation detail, but something saying e.g. that this represents
a connection to an HTTP server (that's an example; I'm not saying
that's what it represents :)) would help.

Looks sensible.

Can this have a comment describing the interface?  (E.g. does it read
a single pkt_line?  How is the caller expected to use it?  Does it
satisfy the interface of some callback?)

libcurl's example https://curl.haxx.se/libcurl/c/ftpupload.html just
calls this read_callback.  Such a name plus a pointer to
CURLOPT_READFUNCTION should do the trick; bonus points if the comment 
says what our implementation of the callback does.

Is this about having peek ability?

Can this overflow?  st_mult can avoid having to worry about that.

This is a number of bytes, but CURLOPT_READFUNCTION expects a number
of items, fread-style.  That is:

	if (avail < eltsize)
		... handle somehow, maybe by reading in more? ...

	avail_memb = avail / eltsize;
	memcpy(buffer,
	       p->request_buffer.buf + p->pos,
	       st_mult(avail_memb, eltsize));
	p->pos += st_mult(avail_memb, eltsize);
	return avail_memb;

But https://curl.haxx.se/libcurl/c/CURLOPT_READFUNCTION.html says

	Your function must then return the actual number of bytes that
	it stored in that memory area.

Does this mean eltsize is always 1?  This is super confusing...

... ok, a quick grep for fread_func in libcurl reveals that eltsize is
indeed always 1.  Can we add an assertion so we notice if that
changes?

	if (eltsize != 1)
		BUG("curl read callback called with size = %zu != 1", eltsize);
	max = nmemb;

Nice.  Same questions about st_mult or just asserting on eltsize apply
here, too.

What does this function do?  Can it get a brief comment?

HTTP_OK is 0 but kind of obscures that.  How about something like the
following?

	if (run_slot(slot, NULL))
		return -1;
	return 0;

or

	if (run_slot(slot, NULL) != HTTP_OK)
		return -1;
	return 0;

That way it's clearer that this always returns 0 or -1.

Interesting.  I wonder if we can make remote-curl less smart and drive
this more from the caller.

E.g. if the caller could do a single stateless request, they could do:

	option git-protocol version=2
	stateless-request GET info/refs?service=git-upload-pack
	[pkt-lines, ending with a flush-pkt]

The git-protocol option in this hypothetical example is the value to
be passed in the Git-Protocol header.

Then based on the response, the caller could decide to keep using
stateless-request for further requests or fall back to "fetch".

That way, if we implement some protocol v3, the remote helper would
not have to be changed at all to handle it: the caller would instead
make the new v3-format request and remote-curl would be able to oblige
without knowing why they're doing it.

What do you think?

Thanks,
Jonathan
