Comment 1 by julius@soundcloud.com:

Correction: several other net.Lookup*() functions (net.LookupIP(), net.LookupMX(), etc.)
seem to all use lookup() in the backend as well, so they should also be affected by this
problem.

Comment 2:

Are you using the net package with cgo enabled (the default) or disabled ?
If cgo is being used then shouldn't this be handled directly by the libc resolver ?

Comment 3 by julius@soundcloud.com:

I am simply building Go from source via src/all.bash. How do I enable using the cgo
versions of those functions? I don't think they're using cgo right now, since local
changes I made to the Go version of lookup() took effect after rebuilding.
Right now my go version is the latest tip:
go version devel +ae79f385177d Wed Jun 12 14:05:13 2013 +1000 linux/amd64

Comment 4:

cgo is enabled by default on all platforms. You can check the status
of cgo with `go env`

go env reports:

So this is the version I just built. I added a panic() just before the Dial("udp", ...)
in net.tryOneName() and sure enough, it panics when I do LookupSRV().
Maybe there is no CGO version of this functionality yet?

Comment 6:

i confirm that there isn't cgo version for this yet.
does getaddrinfo(3) support SRV lookup?
(AI_SRVLOOKUP??)

Comment 7:

Even if we get cgo doing this, the pure Go version should be fixed.

Labels changed: added priority-later, go1.2, removed priority-triage.

Status changed to Accepted.

Comment 8 by fish@soundcloud.com:

Seems like it's not supported: http://sourceware.org/bugzilla/show_bug.cgi?id=2099

Comment 9:

Let's get the pure DNS version working, but no cgo fallback to it.

Labels changed: added go1.2maybe, removed go1.2.

Comment 10 by fish@soundcloud.com:

Considered including https://github.com/miekg/dns in the core? Might be too heavy, but
it's a great, idiomatic library in a similar style to net/http.
