fix#7947
move `BasicHost.AutoNat` to a private field (it has no public method and shouldn't be accessed afaik.
Instead add a setter for config that sets it while holding the address mutex to prevent reads of the
field at the same time.
This patch updates go-libp2p for the stream interface changes in go-libp2p-core
0.7.0. This is a _significant_ breaking change to streams and all users should
read https://github.com/libp2p/go-libp2p-core/releases/tag/v0.7.0. In practice,
this change should remove a significant footgun.
TL;DR:
* `Stream.Close` now behaves like `net.TCPConn.Close`.
* There is a new `Stream.CloseWrite` (send an EOF) and `Stream.CloseRead` (close
for reading), behaving like their counterparts in `net.TCPConn`.
Previously, we'd construct addresses like `/ip4/.../udp/...` instead of
`/ip4/.../udp/.../quic` because we'd use mapped addr (ip + transport + port)
instead of the full external address (ip + transport + port + other
transports...).
* fix: use all interface addresses when we can't find the default route
* fix: don't add advertise unspecified addresses
* fix: resolve addresses before looking up observed addresses
* fix: only advertise global unicast
* fix: filter link-local addresses from advertisement
* test: fix basic host addr tests
We switched `listenAddrs` from the _interface_ addresses to the raw addresses we
were listening on. Unfortunately, we needed the resolved addresses later in the
function when resolving port mappings.
0. NEVER call `peerstore.SetProtocols(p)` (clear the protocol set). Given the
new identify events, if someone looked in the peerstore at the wrong time, they
could decide that the peer no longer speaks some protocol.
1. Reliably wait for identify before trying to open a stream. The old logic was
_really_ racy.
2. Avoids potentially calling identify on the same connection multiple times.
3. Calls identify as early as possible. Previously, we'd invoke identify on
inbound connections using an event that was only invoked _after_ all `Connected`
event handlers completed. Now we invoke identify from a `Connected` handler.
Instead of using a global variable.
This also:
* Adds an option to the identify service to set the user agent.
* Removes the ability to pass an identify service to NewHost as any reasonable
Identify service already needs to be constructed with an instance of the host.
