Bastian Köcher f4b287c7c4 Disable log reloading by default (#9966)
* Disable log reloading by default

This disables the log reloading that was enabled by default. The problem
is that the log reload implementation of `tracing` is using a lock to
make the layer replaceable. This lock needs to be locked every time we
need to check if a particular target is enabled (assuming the log level
is high enough). This kills the performance when for example
`sometarget=trace` logging is enabled.

Bastian Köcher c09d52ead7 Use tokio runtime handle instead of TaskExecutor abstraction (#9737)
* Use tokio runtime handle instead of TaskExecutor abstraction

Before this pr we had the `TaskExecutor` abstraction which theoretically
allowed that any futures executor could have been used. However, this
was never tested and is currently not really required. Anyone running a
node currently only used tokio and nothing else (because this was hard
coded in CLI). So, this pr removes the `TaskExecutor` abstraction and
relies directly on the tokio runtime handle.

Besides this changes, this pr also makes sure that the http and ws rpc
server use the same tokio runtime. This fixes a panic that occurred when
you drop the rpc servers inside an async function (tokio doesn't like
that a tokio runtime is dropped in the async context of another tokio
runtime).

As we don't use any custom runtime in the http rpc server anymore, this
pr also removes the `rpc-http-threads` cli argument. If external parties
complain that there aren't enough threads for the rpc server, we could
bring support for increasing the thread count of the tokio runtime.

* Fix tracing spans are not being forwarded to spawned task (#8009)

* Fix tracing spans are not being forwarded to spawned task

There is a bug that tracing spans are not forwarded to spawned task. The
problem was that only the telemetry span was forwarded. The solution to
this is to use the tracing provided `in_current_span` to capture the
current active span and pass the telemetry span explictely. We will now
always enter the span when the future is polled. This is essentially the
same strategy as tracing is doing with its `Instrumented`, but now
extended for our use case with having multiple spans active.

Bastian Köcher d698d01378 Inform sync explicitly about new best block (#7604)
* Inform sync explicitly about new best block

Instead of "fishing" the new best block out of the processed blocks, we
now tell sync directly that there is a new best block. It also makes
sure that we update the corresponding sync handshake to the new best
block. This is required for parachains as they first import blocks and
declare the new best block after being made aware of it by the relay chain.

* Adds test

* Make sure async stuff had time to run

Max Inden bd2dbc055c client/network: Remove option to disable yamux flow control (#7358)
With the `OnRead` flow control option yamux "send[s] window updates only
when data is read on the receiving end" and not as soon as "a Stream's
receive window drops to 0".

Yamux flow control has proven itself. This commit removes the feature
flag. Yamux flow control is now always enabled.

* client: Replace `unsafe_rpc_expose` with an `RpcMethods` enum

which can be either Default, Safe or Unsafe. The idea is to have the
following:
|                       | --rpc-external=false  | --rpc-external=true   |
|---------------------  |-------------------    |-----------------      |

| --rpc-methods=Safe    | unsafe calls denied   | unsafe calls denied   |
| --rpc-methods=Unsafe  |                       |                       |
Since the previous `unsafe-rpc-expose` option was confusing.

* client: Only warn against exposing externally unsafe RPC method set

* Apply suggestions from code review

Co-Authored-By: Cecile Tonglet <cecile.tonglet@cecton.com>

* cli: Rephrase doc comment for rpc_methods config

* Improve debuggability of build_spec_works

...by printing to stderr the stderr of the command. This is normally
suppressed for succesful tests but not for failing ones - if that's the
case then it's useful to see the test failure reason inline rather than
having to execute the command separately ourselves.

* Rename RpcMethods::{Default => Auto} variant

* Update bin/node/cli/tests/build_spec_works.rs

Toralf Wittner 421ef498f4 network: Only insert global addresses into the DHT. (#5735)
* network: Only insert global addresses into the DHT.

Currently every address reported via libp2p-identify is inserted into
the DHT which thus contains a multitude of unreachable addresses such
as from 127.0.0.0/8 or 10.0.0.0/8.

Issue #5099 suggested a dedicated service over UDP to gauge the
reachability of an address, which would however incur extra I/O costs
and be of limited use.

As an alternative and simpler tactic, this PR only allows global IP
addresses to be inserted into the DHT unless an explicit command-line
flag `--allow-non-global-addresses-in-dht` is given or a node is
started with `--dev`. This opt-in behaviour is meant to allow
site-local networks to still make use of a DHT.

* Enable non-global in more test setups.

* Replace command-line option with different name.

* Another test fix.
