First, how we record "our_funds" and then apply pushes vs lease_fees
(for liquidity ad buys/sales) was exactly opposite.
For pushes we were reporting the total funded into the channel, with the
push representing how much we'd later moved to the peer.
For lease_fees we were rerporting the total in the channel, with the
push representing how much was already moved to the peer.
We fix this (from a view perspective) by re-adding lease fees to what's
reported in the channel funding totals. Since this is now new behavior
(for leased channel values), we added new fields so we can take the old
field names thru a deprecation cycle.
We also make it possible to differentiate btw a push and a lease_fee
(before they were all the same), by adding to new fields to `listpeers`:
`fee_paid_msat` and `fee_rcvd_msat`.
This allows us to avoid math in the bookkeeper, instead we just pick
the numbers out directly and record them.
Fixes#5472
Changelog-Added: JSON-RPC: `listpeers` now has a few new fields for `funding` (`remote_funds_msat`, `local_funds_msat`, `fee_paid_msat`, `fee_rcvd_msat`).

The CLN API is rather strict about the fact that we should skip
providing a field whenever it is empty. Checking for `is_none` would
still include empty arrays.
Changelog-Fixed cln-rpc: Optional empty arrays will no longer be serialized in requests
This allows us to re-use existing tests (assuming the call and fields
are covered by `cln-rpc` and `cln-grpc`) to test the full roundtrip
from test over the grpc interface to the json-rpc interface and back
again.
You can switch to the grpc interface by setting the `CLN_TEST_GRPC`
environment variable to 1, but for now only very few shims are
implemented (due to the non-generated nature of LightningRpc).
To test the grpc interface we'll want to emulate the JSON-RPC
interface as best we can, hence when talking to the grpc interface we
want to convert back into a parsed JSON format as LightningRpc would
have returned it. This is just the simplest way of closing the loop
here:
```
pyln-testing --grpc-> cln-grpc --grpc2json
^ |
| v
| JSON-RPC
| |
TEST v
^ CLN
| |
| v
pyln-testing <-grpc2py-- cln-grpc <- json2grpc
```
These may eventually end up in pyln-client, as they allow talking to
the GRPC interface exposed by cln-grpc, however for now they are used
for testing only. Once we have sufficient API and test coverage we can
move them and leave imports in their place.
We were overriding the name right when loading, which is bad since in
some languages we use the method name as tag in the requests, thus
renaming causes us to call something that isn't defined.
Changelog-Fixed: cln-rpc: Fixed a naming mismatch for `ConnectPeer` causing `connectpeer` to be called on the JSON-RPC
This was introduced to allow creating a shared secret, but it's better to use
makesecret which creates unique secrets. getsharedsecret being a generic ECDH
function allows the caller to initiate conversations as if it was us; this
is generally OK, since we don't allow untrusted API access, but the commando
plugin had to blacklist this for read-only runes explicitly.

that doesn't mean that connectd has processed it! This means when
we connect it may still send us "old" gossip.

Over time, it has cost us more developer cycles than it has gained.
It has hidden intermittant bugs, and allowed cruft to accumulate:
when we eventually tried to figure out what was going wrong, the
actual change which caused it was now stale and forgotten.

So this was quite a journey:
- We want relative depdendencies (using the `path` argument) whenever
developing locally. Otherwise we would have to install each
dependency every time we change a single character, which
undoubtedly would cause us to waste time trying to debug an issue
just because we forgot to install.
- When publishing however we want to rely on the version number,
since the repo context gets lost upon publishing, and path
dependencies cause failures.
The solution then it seems is to use `dev-dependencies` (not that
surprising once you find it) with relative paths, so that `poetry
install` uses these over the normal dependencies (no idea how they
dedup them) and use `dependencies` when publishing. The paths are
still in there when publishing, but `pip install` ignores them.
I checked that `poetry install` from an unrelated project doesn't
accidentally use the path dependencies, even when adding them as
dev-dependencies. This should hopefully also allow installing them
as a repo link, though I can't test that right now.

* close `feerange` is a feerate type.
* datastore/deldatastore/listdatastore `key` can be singleton.
* delexpiredinvoice: `maxexpirytime` is not required, is a u64.

* fundpsbt: many fields are u32 not number (JSON for int or float).
* invoice: `msatoshi` can be "any".
* invoice: `expiry` has a type (now must be numeric).
* invoice: `exposeprivatechannels` can be bool or array of scids.
* invoice: `deschashonly` added
* keysend: there's no "float" type, use "number" or "u32" etc.
* keysend: `routehints` is a valid arg, as is `extratlvs` (EXPERIMENTAL_FEATURES)
* listdatastore: `key` is not required.
* newaddr: `addresstype` can be "all"
* pay: `exemptfee` is "msat", new fields `locaofferid` and `exclude`
* sendonion: was mis-formatted, missed `localofferid` and `groupid` fields.
* sendpay: add `localofferid` and `groupid` params.
* signpsbt: add `signonly` param.

Make it always a number; this makes the JSON request specification

We are inferring the field numbers on the fly, which isn't really
compatible with the way GRPC field numbers work, i.e., they must be
stable while the IDL file evolves. So far when a field was added in
the middle of a struct or removed all subsequent fields would get
renumbered, essentially breaking any client that was using the old
scheme.
We now add a meta file `.msggen.json` that keeps track of the numbers
assigned so far, so they can be reused, and new ones can be generated
not to conflict with existing ones. This file is intentionally kept
generic, so other generators can add more information that has to be
managed across runs.
Changelog-None
We must use `None` for default arguments since otherwise they aren't
filtered out when serializing the request. In addition default
arguments to functions are initialized once and, if mutable, could
persist internal changes across function calls.
Changelog-None
`listpeers` is a rather deeply nested structure which has a couple of
caveats, namely that we use the same enum multiple times, which causes
naming clashes. So we truncate the state_changes[]. We can later map
them if needed, but it'll get much easier once we have an abstract
model description that isn't JSON schema, which unrolls all types,
causing us to generate those enums multiple times.
There is at least one clash with a built-in for the grpc server trait,
namely `connect` so we add support for renaming a method when
generating the scaffolding
The server doesn't do much more than unwrapping the request from its
grpc envelope, convert it into the matching JSON-RPC binding struct,
initiate the RPC connection (until we have connection pooling), and
then forwards the converted request. The inverse then happens for the
result.
Unfortunately we can't do any smart parsing here since
wiregen does not support switch/type cases for different
substructure unions yet. So just give us a pointer we can use.
But this requires a watch-only wallet, and python-bitcoinlib doesn't support
multiple wallets, so we need to unload the original one, but then we need
to generate a block, so that can't generate a new address, so we need
an address arg to generate_block.

We build an in-memory model of what the API should look like, which
will later be used to generate a variety of bindings. In this PR we
will use the model to build structs corresponding to the requests and
responses for the various methods.
The JSON-RPC schemas serve as ground-truth, however they are missing a
bit of context: methods, and the request-response matching (as well as
a higher level grouping we'll call a Service). I'm tempted to create a
new document that describes this behavior and we could even generate
the rather repetitive JSON schemas from that document. Furthermore
it'd allow us to add some required metadata such as grpc field
numbering once we generate those bindings.

but instead it produced:
/private/tmp/ltests-1p0v5z1j/.locks/lock-1631090663.105848
The mismatch resulted in a hang inside flock.
Path .resolve() seems to be causing problems for others as well. It appears the library was not meant to handle complex path situations and isn't maintained as such (see link reference).
Since we have already built a full path here anyway, the call to .resolve() appears redundant.

Do not mix bytes and GossmapNodeId when accessing Gossmap.nodes dicts.
Therefore the definion got GossmapNodeId also needed to be pulled to the
beginning of the file.
This reads the `gossip_store_channel_amount` that always follows the
`channel_announcement` messages. Therefore it uses an internal variable
_last_scid to know what channel has been added last time.
This is more efficient than converting them all to Pubkeys: about 3.8
seconds vs 5.4 seconds. Usually treating them as raw bytes is what we
want anyway.

Without this, we cannot pip install pylightning and pyln-client in the
same environment anymore, as it tries to pull in an incompatible version
of pyln-client.
Changelog-None
The issue is that the new keyword `force_lease_closed` was being set
even if the user didn't specify it, which results in breakage if this
new pyln version talks to older c-lightning nodes that don't have this
keyword yet. By setting the default to `None` it gets filtered out if
the user has not explicitly set it, but still retains the `True` /
`False` values if they did.
Changelog-None Issue is not present in released versions
Since we now use 'compact_lease' to gate an open (if the rates have
changed, we fail), we no longer need to rely on query rates for figuring
things out, so we make it dev-only.
Changelog-Changed: JSON-API: queryrates is now developer only
We need to know what the lease we're expecting is. To do this
we pass around the hex encoded portion of the wire format.
We can use this passed in expected lease rates to confirm that the peer
is, in fact, using the same rates as what we have currently.
Changelog-Added: JSON-RPC: fundchannel, multifundchannel, and openchannel_init now accept a 'compact_lease' for any requested funds
By default, we won't close a channel that we leased to a peer.
You can override this with the `force_lease_closed` flag.
Changelog-Added: JSON-RPC: close now has parameter to force close a leased channel (option_will_fund)
Using a 'feestep' is more restrictive than you'd want, instead we
enforce that the next feerate must be at least 1/64th more than the
last, but put no upper limit on it

Users are more upset recently with the cost of unilateral closes
than they are the risk of being cheated. While we complete our

get less aggressive (we already have 34 or 18 blocks to close
in the worst case).

- Commit transactions were "2 CONSERVATIVE" now "6 ECONOMICAL".
- HTLC resolution txs were "3 CONSERVATIVE" now "6 ECONOMICAL".
- Penalty txs were "3 CONSERVATIVE" now "12 ECONOMICAL".
- Normal txs were "4 ECONOMICAL" now "12 ECONOMICAL".

We will eventually start emitting and dispatching custom notifications
from plugins just like we dispatch internal notifications. In order to
get reasonable error messages we need to make sure that the topics
plugins are asking for were correctly registered. When doing this we
don't really care about whether the plugin that registered the
notification is still alive or not (it might have died, but
subscribers should stay up and running), so we keep a list of all
topics attached to the `struct plugins` which gathers global plugin
information.
You still shouldn't do this (you could get some transient failures),
but at least you have a decent chance if you reinstall over a running
daemon, instead of getting confusing internal errors if message
formats have changed.

This centralizes the setup.py file, and parametrizes it so it can
auto-detect which bolt we are building. It also uses trick 3 from [1]
to avoid importing the package itself during the manifest creation,
which'd cause an import error due to missing dependencies.
[1] https://packaging.python.org/guides/single-sourcing-package-version/
This would lead to errors about missing dependencies when attempting
to install using `pyhon setup.py install`. This is because the
`setup.py` file effectively is the manifest file used to discover
which dependencies are needed, so when using it to detect dependencies
we obviously don't have them yet.
See https://packaging.python.org/guides/single-sourcing-package-version/
We weren't writing out the length of a nested subtype's

Changelog-Added: EXPERIMENTAL JSON-RPC: Permit user-initiated aborting of in-progress opens. Only valid for not-yet-committed opens and RBF-attempts
The semantics don't change, since `lightningd` will use false as
default as well, however setting it to something other than `None`
causes the RPC library to include the parameter in the query, and
since the parameter was introduced only in 0.9.3 and pyln may be used
with older versions this then results in an error about an unknown
parameter.
Setting this to `None` makes sure pyln filters out the argument before
calling.
Changelog-Fixed: pyln: Fixed an error when calling `listfunds` with an older c-lightning version causing an error about an unknown `spent` parameter
I had way too much fun with this and got a bit carried away with the
letter writing. The idea is to be helpful when users start the plugin
from the command line, rather than run it under the control of
lightningd. We also print detailed information about the user-visible
things such as the methods and options exposed by the plugin.

This 'fixes' the `wait_for` helper by removing a pointless final
`time.sleep()`, thus potentially making the method return quicker.
The old code could have had three final states:
- success() := True
- Timeout and success() := True
- Timeout and success() := False
The new code has just two final state:
- success() := True
- Timeout and success() := False
It ensures the final `time.sleep()` is just the right amount before timeout.
And more importantly making it more readable :-)

We are printing `repr(obj)` which is not pretty-printed, hard to read,

Changelog-Added: pyln-testing: The RPC client will now pretty-print requests and responses to facilitate log-based debugging.
We were getting a couple of starvations, so we need a fair filelock. I
also wasn't too happy with the lock as is, so I hand-coded it quickly.
Should be correct, but the overall timeout will tell us how well we
are doing on CI.
We were getting a number of incompatibility warning due to the
dependencies being expressed too rigidly. This losens the requirement
definitions to being compatible with a known good version, and while
we're at it we also bump all outdated requirements.
we got rid of push_msats for dual funded channels. this assumes that hte

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.

Logs may contain non-ASCII and non-UTF8 symbols, which crashes the

undecodeable symbols instead, and handle the issue further up the

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.
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.
Since we start a new instance of postgres for each test we may end up swamped
