Using the 405d7dd commit
Using bip39 / 32 specifications
use the dry-run endpoint to run non-state-changing contract calls
Remove defaults settings, and add them to the NodeClient init function:
This happens for example in the cli account sign command
when setting the fee to a number it doesnt get applied correctly
When trying to call spend I get an error message and it fails
I was hopping the transaction went on without issues
it returns

This issue affects the aeternity tipping bot directly because it can only retry for a few seconds before continuing or expecting an answer, also the error is not clear at all

I pointed it to another node (namely the one used by the explorer ( roma-net.mdw.aepps.com ) and it failed in the same exact way. This error was not here before. I tried several versions of the aepp-sdk-python, starting with the roma supported one up to and including current develop branch
Using subprocess.run(stdin=....), the Python CLI never picks up the extra input, and thus fails the CLI interface tests, even though it behaves properly on an actual terminal.
State Channel Creation and Initialization
Ping websocket connection every 10 seconds so it stays alive.
State Channel - Leave, Shutdown and Disconnection
I tried the
aecli account spend mywallet ak_XXXXXXXXXXXXXXXXXXXXXXXX 5000
and I get an error saying:
"Error: Sender account not found"
And I don't understand what is going on.
Using tag 0.25.0.1b1
Currently the CLI can only use environment variables to be configured. Allow using flags for configuring those as well.
The process of verifying an arbitrary message is not straightforward.
The sdk should provide a helper function in the signing submodule for signature verification.
Implement WebSocket Management for State Channels
Since ae has released v1.0.0, I just wonder will this sdk support it? I tried ./aecli chain top and got an error Unable to understand node reply, perhaps is not an epoch node or is too old?
I created my keys using this
epoch keys_gen PASSWORD
Is there any way to import it into this format that look slike a json? 😢
I mistakenly added spaces to my password and I find no way to replace my password.
Support requests with a tag that doesn't even exist?
That's just mean.
Send transaction to succeed as it says in the documentation
It returns a Error: Invalid transaction

epoch v1.1.0 / docker aeternity/epoc:v1.1.0
aepps-sdk-python v1.1.2 / commit 302c8ec
Version 1.2.0 and above of the aeternity node provide the network_id in the node status:
it can be used to select automatically the correct network id.
In case the network id is not present it should use the mainnet one or raise an error

+Feature request
Would it make sense to use this to sweep and account?
Or to spend the total amount in the account without having to perform a balance and withdraway independantly?
It should ne possible to call a contract by name (aens)
Update cli with separation from offline and online sets of commands
To make it easier to generate changelogs
Hello,
Here is what I just did with 1.1.1 freshly installed:
aecli account create test
Enter the account password []:
<account>
Address ___________________________________________ ak_b'EnvNWbub5PJAF6M4UiY7HbZymtaWkr1dU5gfxLLCxNWFV54zz'
Path ______________________________________________ /data/cryptowallets/aeternity/wallet/test
</account>
Then I try to check my balance:
aecli account balance test
Enter the account password []:
Error: Invalid public key
Problem is the same is happening with a real account I have with token owned by the address, so I'm still wondering if the coin are lost or not......
That's a serious issue...
Currently balance returns a string that does not match the value returned by the node.
for example it returns 9109999999999999744 when the node shows 9110000000000000000
This is a rounding issue in python's long int implementation that the aepp-sdk-python is not prevending or working around
from the command line client
Implement support for hd wallet
When requesting the private key from a script, there are some prompts that make it unusable, it would be great if there was an option you can use to prevent the command from stopping to ask for validation.
payload is not an option you can use when calling account spend, it would be really nice if it could be supported.
