Bryan Boreham eef311ba69 Resolve name to IP address when removing connected targets 2014-10-10 11:45:10 +01:00
Matthias Radestock cf9c479727 check that the go stdlib was built with the required options 
AFAICT, go build tags are a compile-time only construct, so there is
no way to query whether a certain package was built with a specific
tag. However, the 'netgo' tag triggers conditional compilation of the
cgo_stubs.go file, and that file name ends up in the executable. (we
could have looked for specific symbols in the 'net.a' library instead,
but that requires locating it first, which is more hassle than it is
worth)

issue #93
 2014-10-09 20:57:56 +01:00
Matthias Radestock 7b02365de8 make dns resolution work in weave container 
by using go's internal DNS resolver.

NB: this relies on go's std library having been compiled with the
netgo build tag, e.g.

   sudo go install -tags netgo -a std

David Wragg c4c06a2dc0 Don't use /tmp for big files 
/tmp is on tmpfs on some systems, so it's better to use /var/tmp
for large files.

Matthias Radestock e7e7de2173 check whether a container has died with docker rather than ps

Cloning instructions
 2014-09-30 15:14:33 +01:00
Michael Bridgen 68c6ba7203 Simplified cloning instructions 
The package name and directory to clone into are almost the same.
(The previous revision also neglected to tell you to cd into the repo
dir)
 2014-09-30 14:51:16 +01:00
Michael Bridgen b3536859d2 Included where to put the repo in the instructions 
Just in case, like me, the person following the instructions does not
know go all that well. You can make it work without doing things
exactly this way, but you may not get what you expect (because it
might, for example, fetch the weave code from github instead of using
the directory you're in).

David Wragg cb0541078a Route multicast packets across the weave network 
Add a route to send multicast packets to ethwe and so across the weave
network.

Without that, multicast packets get sent to the default route, i.e.
to docker's eth0 interface, rather than across the weave network.
So IP multicast doesn't work between containers on different hosts,
even though weaver supports it.

Matthias Radestock 025315363d prevent CPU churn by setting long pcap timeout 
pcap timeouts are a mystery. Setting the timeout to -1 used to reduce
latency, but that was before we started setting immediate mode. And it
turns out that with that timeout, pcap chews through a lot of CPU
polling its file descriptor, checking timers, etc. However, the
behaviour of setting *no* timeout is defined as, err, undefined. So
instead we set a very long timeout indeed. And loop if it expires.
