Docs seem to indicate this should only be required for private
repos, but we have builds failing claiming this needs to be
specified, so just set it manually.
The commitment secret is sensitive - it can be used by an attacker to
steal funds if the node also signs the same transaction. Therefore,
only release the secret from ChannelKeys when we are revoking a
transaction.
For making debugging easy.
If the user gives a different node_secret for transport
layer (`PeerManager`) and for routing msg, internal_announcement_signatures
is the first place it causes an error.
By giving a detailed error message, user will be able to
fix the bug quickly.
... for ChannelError and APIMisuseError
Before this commit, When rl returns error, we don't know
The actual parameter which caused the error.
By returning parameterised `String` instead of predefined `&'static str`,
We can give a caller improved error message.
TestLogger now has two additional methods
1. `assert_log_contains` which checks the logged messsage
has how many entry which includes the specified string as a substring.
2. `aasert_log_regex` mostly the same with `assert_log_contains`
but it is more flexible that caller specifies regex which has
to be satisfied instead of just a substring.
For regex, tests now includes `regex` as dev-dependency.
We use them largely as indexes into a Vec<Transaction> so there's
little reason for them to be u32s. Instead, use them as usize
everywhere.
We also take this opportunity to add range checks before
short_channel_id calculation, as we could otherwise end up with a
bogus short_channel_id due to an output index out of range.
This was just an oversight when route calculation was split up into
parts - it makes no sense for get_route to require that we have a
full route message handler, only a network graph (which can always
be accessed from a NetGraphMsgHandler anyway).
Instead of making the filter_block fn in the ChainWatchInterface
trait return both a list of indexes of transaction positions within
the block and references to the transactions themselves, return
only the list of indexes and then build the reference list at the
callsite.
While this may be slightly less effecient from a memory locality
perspective, it shouldn't be materially different.
This should make it more practical to generate bindings for
filter_block as it no longer needs to reference Rust Transaction
objects that are contained in a Rust Block object (which we'd
otherwise just pass over the FFI in fully-serialized form).
non-mut references to primitives are only excess overhead, so
there's not much reason to ever have them. As a nice bonus, it also
is one less thing to worry about when generating C bindings
This is more consistent with the way we use std::cmp over the
codebase and avoids `use std`, which is only actually needed to
support older rustcs, so feels a bit awkward.
This isn't a big difference in the API, but it avoids needing to
wrap a given NetworkGraph in a RwLock before passing it, which
makes it much easier to generate C bindings for.
In general, we don't need an explicit lifetime when doing something
like:
fn get_thing(&self) -> &Thing { &self.thing }.
This also makes it easier to reason about what's going on in the
bindings generation.
... instead of only the txid.
This is another instance of it not being possible to fully
re-implement SimpleManyChannelMonitor using only public methods. In
this case you couldn't properly register outpoints for monitoring
so that the funding transaction would be matched.
Tests use sources of randomness to produce seeds, preimages, secrets,
and ephemeral data. However, this makes comparing logs between different
test runs difficult. Remove uses of random number generators and the
current time in favor of fixed values in order to make the test output
deterministic.
