e3a1d1a7f3 pyln-client: to_whole_satoshi returns the rounded up satoshi value
A fractional satoshi value isn't really useful; rounding up loses
precision but that's why you called "whole satoshi", wasn't it?

Changelog-Changed: pyln-client: Millisatoshi has new method, `to_whole_satoshi`; *rounds value up* to the nearest whole satoshi

7e867e5ee6 pytest: Add throttler to limit load on the test system
Both my machine and apparently the CI tester machines regularly run
into issues with load on the system, causing timeouts (and
unresponsiveness). The throttler throttles the speed with which new
instances of c-lightning get started to avoid overloading. Since the
plugin used for parallelism when testing spawns multiple processes we
need to lock on the fs. Since we have that file open already, we'll
also write a couple of performance metics to it.

b1aed933e6 pyln: Plugin methods and hooks refuse to set results twice
We had a couple of instances where a plugin would be killed by `lightningd`
because we were returning a result of an exception twice, and it was hard to
trace down the logic error in the user plugin that caused that. This patch
adds a traceback the first time we return a result/exception, and raise an
exception with a stacktrace of the first termination when a second one comes
in.

This can still terminate the plugin, but the programmer gets a clear
indication where the result was set, and can potentially even recover from it.

Changelog-Added: pyln: Plugin method and hook requests prevent the plugin developer from accidentally setting the result multiple times, and will raise an exception detailing where the result was first set.

556725c5ff pyln: Add logging handler that passes records to lightningd
It is often pretty usefuk to use the builtin logging module to debug things,
including libraries that a plugin may use. This adds a simple
`PluginLogHandler` that maps the python logging levels to the `lightningd`
logging levels, and formats the record in a way that it doesn't clutter up the
`lightningd` logs (no duplicate timestamps and levels).

This allow us to tweak the log level that is reported to `lightningd` simply
using the following

```python3
import logging
logging.basicConfig(level=logging.DEBUG)
```

Notice that in order for the logs to be displayed on the terminal or the
logfile, both the logging level in the plugin _and_ the `--log-level`
`lightningd` is running need to be adjusted (the python logging level only
controls which messages get forwarded to `lightningd`, it does not have the
power to overrule `lightningd` about what to actually display).

I chose `logging.INFO` as the default, since libraries have a tendency to spew
out everything in `logging.DEBUG` mode

Changelog-Added: pyln: Plugins have been integrated with the `logging` module for easier debugging and error reporting.

5809cc41f4 pytest: Reduce the db_provider fixture scope to function
For performance reasons we were starting one for each session, which caused
the same postgres DB to be re-used for multiple tests (all test run in the

timeout or a test happens to touch the `db_provider`. It turns out that we
were only saving about 15 seconds on a 1250 second run anyway, which is a

bd811fbd1a pyln: Add safe fallback results for hooks
Hooks do not tolerate failures at all. If we return a JSON-RPC error to a hook
call the only thing the main daemon can really do is to crash. This commit
adds a mapping of error to a safe fallback result, including a warning to the
node operator that this should be addressed in the plugin. The warning is
reported as a `**BROKEN**` message, and should therefore fail any testing done
on the plugin.

Changelog-Fixed: pyln: Fixed HTLCs hanging indefinitely if the hook function raises an exception. A safe fallback result is now returned instead.

the peer who initiates the close can choose his back off step.

We kept track of an URGENT, a NORMAL, and a SLOW feerate. They were used
for opening (NORMAL), mutual (NORMAL), UNILATERAL (URGENT) transactions
as well as minimum and maximum estimations, and onchain resolution.

We now keep track of more fine-grained feerates:
- `opening` used for funding and also misc transactions
- `mutual_close` used for the mutual close transaction
- `unilateral_close` used for unilateral close (commitment transactions)
- `delayed_to_us` used for resolving our output from our unilateral close
- `htlc_resolution` used for resolving onchain HTLCs
- `penalty` used for resolving revoked transactions

We don't modify our requests to our Bitcoin backend, as the next commit
will batch them !

Changelog-deprecated: The "urgent", "slow", and "normal" field of the `feerates` command are now deprecated.
Changelog-added: The fields "opening", "mutual_close", "unilateral_close", "delayed_to_us", "htlc_resolution" and "penalty" have been added to the `feerates` command.

8cad3ffeac pyln: Work around the socket path length on Linux OSs
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

9378be72a9 pyln: Allow users to override the LightningNode class
Quite a few of the things in the LightningNode class are tailored to their use
in the c-lightning tests, so I decided to split those customizations out into
a sub-class, and adding one more fixture that just serves the class. This
allows us to override the LightningNode implementation in our own tests, while
still having sane defaults for other users.

initialization into the node itself means that the LightningNode class now can
be swapped out and customized, without having to wire everything else through.

3418e59d76 pyln: Split pylightning into multiple pyln modules
This is the first step to transition to a better organized python module
structure. Sadly we can't reuse the `pylightning` module as a namespace module
since having importable things in the top level of the namespace is not
allowed in any of the namespace variants [1], hence we just switch over to the
`pyln` namespace. The code the was under `lightning` will now be reachable
under `pyln.client` and we add the `pyln.proto` module for all the things that
are independent of talking to lightningd and can be used for protocol testing.

83e654a106 close: change to a unilateraltimeout argument.
`close` takes two optional arguments: `force` and `timeout`.
`timeout` doesn't timeout the close (there's no way to do that), just
the JSON call.  `force` (default `false`) if set, means we unilaterally
close at the timeout, instead of just failing.

Timing out JSON calls is generally deprecated: that's the job of the
client.  And the semantics of this are confusing, even to me!  A
better API is a timeout which, if non-zero, is the time at which we
give up and unilaterally close.

The transition code is awkward, but we'll manage for the three
releases until we can remove it.

The new defaults are to unilaterally close after 48 hours.

9d4148ce68 pylightning: Warn users of plugins that may break due to extra args
We recently noticed that the way we unpack the call arguments for hooks and
notifications in pylightning breaks pretty quickly once you start changing the
hook and notification params. If you add params they will not get mapped
correctly causing the plugin to error out.

This can be fixed by adding a `VAR_KEYWORD` argument to the calbacks, i.e., by
adding a single `**kwargs` argument at the end of the signature. This commit
adds a check that such a catch-all argument exists, and emits a warning if it
doesn't.

It also fixes up the plugins that we ship ourselves.
