If you actually ran your node with the botched "last_invoice_created_index" typo migration
(fortunately, not release, just master) you can get a db with both the real "last_invoices_created_index" and the bad "last_invoice_created_index" entries.

Clean restart of daemon after a tx-abort is a nice way to work around
the 'persistent' disconnect that we t-bast noticed.
Changelog-Fixed: `dualopend`: Fix behavior for tx-aborts. No longer hangs, appropriately continues re-init of RBF requests without reconnction msg exchange.
Bug Report:
- initiate a channel open eclair -> cln
- wait for the transaction to be published
- eclair initiates rbf, and cancels it by sending tx_abort before exchanging commit_sig
- at that point everything looks good, cln echoes the tx_abort and stays connected
- eclair initiates another RBF attempt and sends tx_init_rbf: for some unknown reason,
cln answers with channel_reestablish (??) followed by an error saying
"Bad reestablish message: WIRE_TX_INIT_RBF"
Diagnosis:
CLN is doing a reconnect after a tx-abort is sent.
Extra Test:
Realized that if we abort, we won't correctly advanced to NORMAL if
blocks are mined while we're in hanging state. CLN should advance
after block containing channel open is mined.

Abstracts search and directory traversal. Adds support for installing
from a local git repository, a local directory, or a web hosted git repo
without relying on an api.
Changelog-Changed: Reckless can now install directly from local sources.
This cause of cascading failure was pointed out by @t-bast: if fees spike and
you don't timeout an outgoing onchain HTLC, you should nonetheless fail the incoming htlc
because otherwise the incoming peer will close on you.
Of course, there's a risk of losing funds, but this only happens if you weren't going to get the HTLC spend in time anyway. And it would also catch any other reason that the downstream onchain goes wrong, containing the damage.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Reported-by: @t-bast
Changelog-Fixed: Protocol: We will close incoming HTLCs early if the outgoing HTLC is stuck onchain long enough, to avoid cascating failure.
This commit addresses an issue to enhance the resilience of core
lightning when receiving node announcements.
According to BOLT 7 (The announcement_signatures Message),
if the node_signature OR the bitcoin_signature is NOT correct,
it is recommended to either send a warning and close the connection or send an error and fail the channel.
In this commit, we take a strict approach. If any error is detected, we
send an error and fail the open channel operation.
This is because the announcement_signatures operation is optional,
and we assume that it must be correct.

This is the simplest solution, not the best, but there's significant risk in try to remove the "we have a path" assumption in the code pay code.
Includes removing a `tal_steal` which was incorrect: the buffer has the same lifetime as the plugin, so if we steal it then things get messy when we free the struct payment.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Added: Plugins: `pay` will now pay your own invoices if you try.
Previously, the "payment" and "invoice" paths were completely separate, but this now calls both. It bypasses htlc_sets (and thus, cannot do MPP), and bypasses the hook too: the former is tied closely to HTLCs, and the hook is also very htlc-centric.
Includes finishing unfinished sentence in sendpay man page, as a bonus.

Changelog-Added: Plugins: `sendpay` now allows self-payment of invoices, by specifying an empty route.
