Users who want to use lightning-block-sync's init module would
be reasonable in wanting to use it in a multithreaded environment,
however because it takes a list of listeners as dyn chain::Listen
without any Send or Sync bound they fail in doing so.
Here we make the type bounds on `chain::Listen` generic across
`chain::Listen + ?Sized`, which the existing bound of `&dyn
chain::Listen` satisfies. Thus, this is strictly less restrictive
and allows for the use of `&dyn chain::Listen + Send + Sync`.
To ensure no-std is honored across dependencies, add a crate depending
on lightning crates supporting no-std. This should ensure any
regressions are caught. Otherwise, cargo doesn't seem to catch some
incompatibilities (e.g., f64::log10 unavailable in core) and seemingly
across other dependencies as describe here:
https://blog.dbrgn.ch/2019/12/24/testing-for-no-std-compatibility/
This makes tests slightly more realistic by delivering
`channel_update`s to `ChannelManager`s, ensuring we have
forwarding data stored locally for all channels, including public
ones.
In 2d3a210897, we increased the
default ping timer in `lightning-background-processor` to ten
seconds from five. However, we didn't change the timer count at
which we disconnect peers if they're not responding, which we
likely should have done. We do so here, as well as update the
documentation for `PeerManager::timer_tick_occurred` to suggest
always ticking the timer every ten seconds instead of five.
Its very confusing to have multiple fields that do the same thing,
one of which isn't even used for its stated purpose anymore after
the previous few commits.
There are currently two issues with
`bolt2_open_channel_sending_node_checks_part1` which counteract
each other and hide that the test isn't testing what it should be.
First of all, the final `create_channel` call actually fails
because we try to open a channel with ourselves, instead of
panicing as the test is supposed to check for.
However, when we fix the create_channel call to panic, when we
drop `nodes[1]` after `create_channel` panics, we fail the
no-pending-messages test as it as an expeted `accept_channel` in
its outbound buffer. This causes a double-panic.
Previously, these two offset each other - instead of panicing in
`create_channel` we'd panic in the Node drop checks.
This fixes both by fetching the `accept_channel` before we go into
the panic'ing `create_channel` call (who's arguments were
corrected).
... by calling it both before and after every chain event in
testing and fuzzing.
This requires fixing some blockchain inconsistencies in
`do_test_onchain_htlc_reorg`, `do_retry_with_no_persist`, and
`do_test_dup_htlc_onchain_fails_on_reload` where we'd connect
conflicting transactions in the same chain.
When handling the broadcast of a local commitment transactions
(with associated CSV delays prior to spendability), we incorrectly
handled the CSV delays on HTLC transactions. This caused us to miss
spendable outputs for HTLCs which were awaiting a CSV delay.
Further, because of this, we could hit an assertion as
`get_claimable_balances` asserted that HTLCs were resolved after
the funding spend was resolved, which was not true if the HTLC did
not have a CSV delay attached (due to the above bug or due to it
being an HTLC claim by our counterparty).
This fixes both bugs, also converting some assertions to
`debug_assert`s to avoid future issues as balance mis-calculation
is not currently an indication of potential funds loss.
Thanks to Cash App for reporting this bug.
This doesn't (appear) to change behavior, however if we have a
non-public node, we assign an A* heuristic of max-u32 fees, which
may result in us de-prioritizing the path in some rare cases around
multi-hop route hints which compete with public nodes.
When we added support for routing through a multi-hop invoice hint
we failed to remove an assertion that we always are able to fill
in features for each hop except the last one. However, when a
multi-hop invoice hint is used, we will not have features for any
of the hinted hops, causing us to panic.
Failing an HTLC with onion error channel_disabled requires encoding a 'flags' field into the failure
packet. However, we were encoding this 'flags' field for all failures packets that were failing on
update_add_htlc with an update (error 0x1000 UPDATE).
Discovered in the course of adding phantom payment failure tests, which also added testing for this bug
In any place where fail_htlc_backwards_internal was called for a phantom payment
failure, we weren't encoding the onion failure as if the phantom were the one
failing. Instead, we were encoding the failure as if it were coming from the
second-to-last hop. This caused our failures to not be parsed properly on the
payer's side.
Places we were encoding failures incorrectly include:
* on failure of a call to inbound_payment::verify
* on a user call to fail_htlc_backwards
Also drop some unnecessary panics when reading OnionHopData objects. This also
enables one of the phantom failure tests because we can construct OnionHopDatas
with invalid amounts.
Lastly, remove a bogus comment
This also fixes a bug where we were failing back phantom payments with the
wrong scid, causing them to never actually be failed backwards (L3022 in
channelmanager.rs)
This new field will be used in upcoming commit(s) to encrypt phantom payment failure
packets.
If we are in the middle of persisting an update to a
`ChannelMonitor` when we shutdown (or crash), we'll start up with
a .tmp file lying around. We should ignore it, as failure to
return from the update call should have prevented the
`ChannelManager` from taking any irrevocable action based on the
update.
We're somewhat protected from any filesystem inconsistency behavior
as the `ChannelManager` will refuse to load if we're outright
missing `ChannelMonitor`s.
Fixes#1330.

The take-self-return-Self idiom in Rust is substantially less
usable than it is in Java, where its more common. Because we have
to take self by move, it prevents using the update methods to
actually update features, something we occasionally want to do.
See, eg, the change in lightning-invoice where we previously had
to copy and re-create an entire vec of fields just to update the
features field, which is nuts.
There are a few places where this makes things a little less clean,
but the tradeoff to enable more effecient and broader uses of the
update methods seems worth it.
