Recent FreeBSD versions use LLVM's lld as a linker, not the GNU ld.
Their behavior slightly differs, so adapt the build system to handle
either one.
* The LLVM's linker prints "undefined symbol:" instead of
"undefined reference to". Tweak tools/mockup.sh to also look for that
message.
* The LLVM's linker may only print the first dozen errors (omitting
the rest to avoid flooding the screen). tools/update-mocks.sh relies
on getting all errors as it extracts the missing symbols' names from
the error output and creates mocks for them. Detect if errors were
omitted and re-run, telling the linker to not omit any. The GNU linker
does not support -error-limit=0, so unfortunately we can't just run
with that option unconditionally from the first attempt.
* Nit: FreeBSD's sed(1) prints "t" for "\t" instead of a horizontal tab.
Use a verbatim tab in the command, instead of "\t" which works on
both.

Some Linux OSs impose a length limit on the path a Unix socket may have. This
is not an issue in `lightningd` since we `chdir()` into that directory before
opening the socket, however in pyln this became a problem for some tests,
since we use absolute paths in the testing framework. It's also a rather
strange quirk to expose to users.
This patch introduces a `UnixSocket` abstraction that attempts to work around
these limitations by aliasing the directory containing the socket into
`/proc/self/fd` and then connecting using that alias.
It was inspired by Open vSwitch code here https://github.com/openvswitch/ovs/blob/master/python/ovs/socket_util.py

We were indiscriminately accessing the `__annotations__` which could cause
issues if the function had been wrapped by some functions such as
`functools.partial`. This just checks that the access is safe before doing it.

If absolute, we can deduce the lightning_dir, the network, and the

This will change some `requirements.txt` of pyln-testing in a way that
it does not require different package version i.e. to `tests/requirements.txt`.
The reason for this is that users are not forced to hassle with pyenv
or virtualenv and could just use `--user`.
```bash
pip install --user -r tests/requirements.txt -r contrib/pyln-testing/requirements.txt

We still close the channel if we *send* an error, but we seem to have hit
another case where LND sends an error which seems transient, so this will
make a best-effort attempt to preserve our channel in that case.
Some test have to be modified, since they don't terminate as they did
previously :(
Changelog-Changed: quirks: We'll now reconnect and retry if we get an error on an established channel. This works around lnd sending error messages that may be non-fatal.

The upgrade here is a bit tricky: we map the two values into the
feerate_state. This is trivial if they're both the same, but if
they're different we don't know exactly what state they're in (this
being the source of the bug!).
So, we assume that the have received the update and not acked it,
as that would be the normal case.

This is an intermediary step: we still don't save it to the database,
but we do use the fee_states struct to track it internally.

The `channel_got_commitsig` we send the lightningd also implies we sent
the revoke_and_ack, as an optimization. It doesn't currently matter,
since channel_sending_revoke_and_ack doesn't do anything important to the
state, but that changes once we start uploading the entire fee_states.
So now we move our state machine *before* sending to lightningd, in
preparation for sending fee_states too.
Unfortunately, we need to marshall the info to send before we
increment the state, as lightningd expects that.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
This uses the same state machine as HTLCs, but they're only
ever added, not removed. Since we can only have one in each
state, we use a simple array; mostly NULL.
We could make this more space-efficient by folding everything into the
first 5 states, but that would be more complex than just using the
identical state machine.
One subtlety: we don't send uncommitted fee_states over the wire.

Indeed, if you waitsendpay without specifying a partid, you are waiting
for 0, which may not exist. Clarify the error msg.

We only tested exactly two equal-size payments; indeed, our finalhop
test was backwards. We only complain if the final hop pays more than
twice msat (technically, this test is still too loose for mpp: the
spec says we should sum to the exact amount).

The pay plugin has been supplying the bolt11 string since 0.7.0, so only
ancient "pay" commands would be omitted by this change.
You can create a no-bolt11 "sendpay" manually, but then you'll find it
in 'listsendpays'.
