suez's Issues

No module named 'virtualenv.seed.via_app_data'

Attempting to install suez on Ubuntu Ubuntu 20.04.3 LTS, but when running poetry install, I am receiving: No module named 'virtualenv.seed.via_app_data'.

I am not sure what version of virtualenv is required, but mine is virtualenv 20.13.0

Latest c-lightning no longer has last_tx_fee, but does have last_tx_fee_msat

One line change in clnclient.py.

Earned fees calculation

The earned fees calculation seems to be double the actual amount. The problem seems to be around here. I'm not sure why fees are counted on both the incoming and outgoing channels? The relay fee is only earned on the outgoing channel.

Commenting out this line results in a calculation that seems closer.

I checked the suez script calculation with this homemade script (could have its own flaw but I did check a daily period by hand and it was correct):

lncli fwdinghistory --start_time -30d --max_events 5000 | grep '"fee"' | sed -nr 's/.*"([0-9]+).*/\1/p' | awk 'BEGIN {total=0;}{total+=$1;}END {print "Total: ",total}'

On my node, even after applying the fix mentioned above, my script and suez still result in an earned fees discrepancy of 16 sats.

[ignore; now working; was:] Failing on Umbrel 0.3.10

Inaccurate local fees calculation

Local fees for each channel are added as an integer value of number of sats, which means that any decimals are lost resulting in the fees displayed in the table might be very inaccurate from the truth.

A solution would be to store the fees as milli sats on the channel object. Both lnd and cln returns the fee as msat. And then divide by 1000 and round to nearest integer when setting the values to be displayed in the table.

I have working code for this running locally. Let me know if you want me to create a PR.

ZeroDivisionError when running without channels

Running wiht a new lnd node without channels:

poetry run ./suez

Traceback (most recent call last):
  File "./suez", line 5, in <module>

ZeroDivisionError: integer division or modulo by zero

Checking for channels can be handled externally, but a friendlier error message would be nice.

Parallel channels for Core Ligthning are not displayed

Found this today when testing CLN v0.11.0.1

Display in Min & Max HTLCs

Hey, it would be great if there is the option to include Min and Max HTLCs of both sides of each channels. Because these are 4 additional figures it is better when they are only displayed if a command line parameter is set.

Regards Steff

CLN - Command "setchannelfee" is deprecated

Seems like the setchannelfee command is deprecated causing the fee update feature to not work.

Tested with version v22.11.1

Remote Node / Umbrel

Looking to run on a remote node (Voltage) and an Umbrel. I think this breaks because the lncli call has to be changed. I tried changing ["lncli"] in lndclient.py def _run with the call commands I would use but it fails still.

Voltage
lncli --rpcserver=xxxxx.votageapp.io:10009 --macaroonpath=/path/to/admin.macaroon --tlscertpath=""

Add the channel balance coefficient and overall imbalance

C.f.: https://arxiv.org/abs/1912.09555 let me know if you have any questions or need help

Commissions for channels, where funds run out

Hello,

What's the point of setting low commissions for channels where your balance is depleted? Thus, you stimulate payments through such channels, but there is no liquidity in them for sending. It is bad for routing (payments through them are more likely will be FAIL but third-party wallets/senders will try to choose these channels as there are low commissions).

It would be quite logical to increase the commission for its part where your local balance is low.

P.S. Honestly, I do not understand - why use here the distribution of Gauss?

ZeroDivisionError while node syncing

Same error as #16 received seemingly while LND 0.12.1 is in a syncing state.

Terminal Web v3

v2 has stopped on 2022-09-09. Now there is v3 ;)

Remote fees

I think remote fees are not calculated correcty:

https://github.com/prusnak/suez/blob/master/lndclient.py#L75

self.channels[cin].remote_fees += fee

The fee on the incoming channel (the remote party fee) is their base fee + amount * fee_rate but here you're using our fee.

This should be:

`self.channels[cin].remote_fees += (self.channels[cin].remote_fee_base + forward_amount * self.channels[cin].remote_fee_base / 10000) / 1000

or something along these lines.

What do you think @prusnak ?

corelightning + suez

Suez was working great for me until recently. I appears to not be able to modify fee rates anymore. I was running an outdated version, and did a git pull to update. Now, I get these errors when running any operation from suez, any idea how to fix it?

Add arguments to show only public or only private channels

Not sure if this feature makes sense? But I find it very useful to look at public and private channels separately. Could be implemented by adding '--only-public' and '--only-private' arguments and only show channels accordingly.

Use RPC instead of lncli

It would be very nice to use the RPC API provided by lnd rather than relying on lncli being installed. I am trying to run suez in a Docker container and I'd rather not install lncli when it could directly communicate over RPC with lnd from another container.

I saw that that the choice of backend is abstracted away in separate classes, one for lnd and one for c-lightning. So in theory I could just add another one for RPC. Did somebody already look into that? Or is there some good reason to rely on lncli?

Confirming: is it dangerous to interrupt the script (e.g., via CTRL+C)?

https://docs.lightning.engineering/lightning-network-tools/lnd/safety#prevent-data-corruption

The following (non-exhaustive) list of things can lead to data corruption:
[...]
Aborting channel operation commands (see next chapter).
[...]

Next chapter (https://docs.lightning.engineering/lightning-network-tools/lnd/safety#dont-interrupt-lncli-commands):

Things can start to take a while to execute if a node has more than 50 to 100 channels. It is extremely important to never interrupt an lncli command if it is manipulating the channel database, which is true for the following commands:
[...]
updatechanpolicy
[...]

Thus, I assume we should "never interrupt" suez.py?

connecting to remote node?

My node is not local, but I think suez assumes it does.

I've tried passing arguments to the client and changing the config but no luck.

Any tips?
