Previously, in each of our fuzz tests we had a dummy test which
had a hard-coded hex string which it passed into the fuzz target
so that when a failing test case was found, its hex could be
copied into the test and you could run cargo test to analyze the
failure. However, this was somewhat unwieldy as converting large
tests back and forth between hex and raw files is quite annoying.
Instead, we replace each of those tests with a test in each target
that looks for files in fuzz/test_cases and runs each file it finds.
Since we're editing every bin target anyway, we also automate adding
no_main to libfuzzer builds with #![cfg_attr].
The Features::new() method is nonsense and doesn't describe what
features were being set - we introduce an empty() and supported()
constructors instead.
This merges local and global features into one struct, which is
parameterized by where it appers. The parameterization restricts
which queries can be made and which features can be set, in line
with the latest BOLT 9.
Closes#427.
Simplify interfaces between ChannelMessageHandler and PeerManager,
by switching all ChannelMessageHandler errors to HandleError sent
internally instead of being return. With further refactors in Router
and PeerChannelEncryptor, errors management on the PeerManager-side
won't be splitted between try_potential_handleerror and HandleError
processing.
Inside ChannelManager, we now log MsgHandleErrInternal and send
ErrorAction to PeerManager.
On a high-level, it should allow client using API to be more flexible
by polling events instead of waiting function call returns.
We also update handle_error macro to take channel_state_lock from
caller which should avoid some deadlock potential for some edges
cases.
Filter out IgnoreError in handle_error macro, update test in
consequence.
Instead of having in-memory access to the list of private keys
associated with a channel, we should have a generic API which
allows us to request signing, allowing the user to store private
keys any way they like.
The first step is the (rather mechanical) process of templating
the entire tree of ChannelManager -> Channel impls by the
key-providing type. In a later commit we should expose only public
keys where possible.
