Hi, Florian!

There was some discussion on this previously. I did some research,
and it appears that the service discovery mechanism currently
standardized by the IETF do not fulfill the needs of GNU arch, due to
its multi-protocol support. Maybe DNS-SD/Rendezvous is better in this
regard, I haven't looked at it.
No, this is definitely an issue: presumably arch itself has no way of
knowing whether an archive you create is publicly accessible or not due
precisely to not caring whether it's on an FTP site, a web site, etc.
So "public registry via DNS-SD" is clearly an orthogonal issue. In
addition to that, "services" are presumed to own their port, but it
clearly doesn't make sense to say "there's an arch service on port
XXX," when the port in question is an HTTP port, FTP port, SSH port...
Conversely, on the receiving side, we might consider a daemon process
that listens for new repositories and, when it finds them, "registers"
them (in the arch sense) automagically, vs. requiring the user to run
tla to discover them. OTOH, perhaps it would suffice to have "tla
archives" lazily search the space, although that seems to have a lot of
potential for performance issues.
The point is that this is exactly the kind of conversation I want to
have: here's an idea. What are the issues surrounding implementing the
idea? Are they surmountable? If not, why not, and what might we do
instead?
Anyway, I think it's premature to standardize a naming/directory
service for arch archives at the moment. At least for me, the most
relevant usage patterns are not yet clear enough. Some more
experience in this area should enable us to come up with better
requirements.
Experience in what area? Using arch, using naming/directory
services...? It seems to me fairly apparent that, while having a
"global distributed namespace" is nice, having to define names in the
namespace by hand doesn't scale. Given that there's a technology that's
included in one popular OS, is available for others, and has been
deployed in at least one CVS client/server pair, it seems worthy to at
least consider how arch might follow suit. Note that I'm not saying
"accept me as a commiter or else;" I'm merely saying that a reasonable
discussion as to how such an endeavor might (or might not!) work would,
I think, be beneficial to the arch community. At least, it would
certainly be appreciated by me.
Best regards,
Paul
