The `tmpctx` is free'd before the error is read out/sent over the wire;
there's a call that will copy the array before sending it, let's use
that instead and take() the object?

This adds the `cln_parse_rpcversion` helper that is already used in
various plugins to pyln-client, so it does not need to be copied
around anymore.
Changelog-None
The htlc_budget only exists iff the hint is a 'local' one; we were
failing to write to the htlc_budget field for non-local cases.
To avoid this, we make `local` into a struct that contains the fields
that pertain to local-only payments (in this case, `htlc_budget`).

In various circumstances we can start a reconnection while one is
already going on. These can stockpile if the node really is unreachable.

Fixes: #5654
Changelog-Fixed: lightningd: we no longer stack multiple reconnection attempts if connections fail.

1. Allow 'any' as an option to zeroconf-selective.py plugin so we can use
it in line_graph where we don't know ids yet.
2. Use modern helpers like line_graph and remove debugging statement.
3. Don't use listchannels(): it's true that it shows local channels as well,
but that's a quirk I'd like to remove.
4. Make flake8 happy.
5. Rename to be more specific now it's a more narrow test.
I manually tested that the test still failed with the fixes removed, too,
so it is still the same test!

If we only specify the node_id, we get the "first" channel.
Closes: #5803
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
Changelog-Fixed: Plugins: `pay` uses the correct local channel for payments when there are multiple available (not just always the first!)
We fixed most of them. Now hone in to the case which fails: `pay`
when it needs to use the direct zero-conf channel.

Modifications from issue #5803 to work here:
1. import json
2. Add xfail
3. Increase channel sizes by 10x so we can open them
4. Fix plugin path

We can actually catch l2 with HTLCs still closing and mine blocks,
then it force closes due to HTLC timeout.

I noticed that our subtables were not being cleaned, despite being "ON
DELETE CASCADE". This is because foreign keys were not enabled, but
then I got foreign key errors: rowid cannot be a foreign key anyway!
So create a real "rowid" column. We want "ON DELETE CASCADE" for
nodes and channels (and other tables in future) where we update
partially.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
When doing the updates on the plugin repo, I discovered that
this helper function got broken by the `listpeerchannels` upgrade.
Its rarely used in the main repo, just at the end of the pyln-testing
'pay' helper.
If unfixed, this bug may result in test flakes when using the `pay`
helper, because its not correctly waiting for all HTLCs to be resolved
before returning.
Changelog-None
The leak-detector can't find unconnected_htlcs_in on the stack and
incorrectly flags this as a leak. However, it is appropriately tal
allocated and freed.
Changelog-None
Valgrind correctly reports it as uninitialized for this log message, and
the only way this can happen is channel_hints_update() when we receive a
temporary_channel_failure. Put a dummy value here in this case.

There were cases where address it's empty, and this cases are not right if the
field is considered optional.
This makes it required and add the field also when `--offline` is set.

Changelog-None
The sections on SQLite Litestream, sqlite3 .dump and VACUUM INTO commands
were to be removed six months after 0.10.3, due to issues observed in #4857.
We now recommend using --wallet=sqlite3://${main}:${backup} instead.
Also, put the "added" lines in the request schemas for new commands:
this doesn't do anything (yet?) but it keeps `make schema-added-check` happy.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This *would* be a 1-line change (add it to Makefile) except that we
previously assumed a "list" prefix on commands.
These use the default refreshing, but they could be done better using
the time-range parameters.

We now add tables to the strmap as we allocate them, since we don't

For now, we ignore every deprecated field, but put in the logic so
that future deprecations will work as expected.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
`"deprecated": true` is obsolete; we don't document them anyway.
Where it would have otherwise changed the GRPC wrappers, I actually put the
version number in.
We allow "listchannels" to have "satoshis" since we have some tests
that run in deprecated-api mode.
