[gentoo-dev] Global useflags zeroconf and avahi

[Andreas K. Huettel]

[-- Attachment #1: Type: Text/Plain, Size: 971 bytes --]


Hi everyone, 

first of all, I'm not really an expert in this stuff, so feel free to tell me 
about any mis-assumptions...

As far as I can see, we have two global useflags:
avahi - Add avahi/Zeroconf support
zeroconf - Support for DNS Service Discovery (DNS-SD)

"Zeroconf" describes a service autodiscovery and autoconfiguration standard, 
see [1]. Avahi is the implementation of that standard which we have in the 
portage tree [2]. Other implementations are mDNSResponder (which was in the 
tree some time ago but got kicked out) and Apple's Bonjour (which never was in 
the tree and probably never will be).

I would like to suggest unifying use-flag usage, and use "zeroconf" anywhere.

Opinions?

Cheers, 
Andreas

I thought this discussion was over last time it came around.

iirc the conclusion was what you wrote, use zeroconf unless there is a
special reason (none afaik in tree).

Parts of zeroconf (namely IPv4LL) are also implemented by dhcpcd and other
software without using avahi.

Sounds good. Do you think the same should apply to non-mDNS/DNS-SD based
zeroconf like UPnP/SSDP?

Heh. Indeed... see 
http://marc.info/?l=gentoo-dev&m=124578830315474

Seems like just noone actually did the work.

Below is the list of ebuilds declaring a use-flag "avahi". May I respectfully 
suggest you all start sorting this out then? :) 

As usual, be careful with use dependencies bla bla...

Kill zeroconf and use "dnssd", "upnp", "ssdp". Problem solved?

I very much like the approach in principle, though. Digging briefly into
Wikipedia[1], UPnP has several components:

* AutoIP (IPv4LL)
* SSDP (So, a separate "ssdp" USE flag may not be necessary)
* SOAP (If I read this correctly, this is the encoding of its RPC
  mechanism)
* GENA (A pub/sup architecture)

(For those that read the link, I'm obviously leaving out the
'Description' section...I don't know what that would be called, really.)

I don't know enough about real-world use of UPnP to say which of these
components are most fruitfully separated out of UPnP, USE-wise. If I had
to guess, I'd probably suggest:

* Break out SSDP and AutoIP,
* Have UPnP imply SOAP and GENA
* Have UPnP depend on the enabling of SSDP and AutoIP.

Or tie all of it into a single USE flag and be left with 'upnp' and 'ssdp'.

I'm not too enthusiastic about that.

USE=zeroconf on pulseaudio is a bit easier to understand than
USE=ssdp, for example.

The flags should be practical. I have no use for DNS-SD and other
magical junk, yet use UPnP/IGD for port forwarding. The flags should
let me just enable just that without pulling all other possible
variants I won't use.

That said, USE=upnp was cleaned up a while ago. I don't think it should
be integrated with zeroconf.

Ah don't worry I'll file one eventually. Just giving a kick here first... :)

Yeah I don't think it should be merged into zeroconf even though it
shares some of its technical base.

Imho, zeroconf == dnssd/mdns & ipv4ll and upnp/upnp-av are as described
in use.desc
