Bug Fixes

Account.get_voting_power() method Not Functional on HF20 RPC Nodes

The post about the bug can be found here.
get_voting_power was fixed in commit c01e10d
by using:

• self["voting_manabar"]["current_mana"]
• self["voting_manabar"]["last_update_time"]

Example with working get_voting_power():

from beem import Steem
from beem.account import Account

stm = Steem(node="https://api.steemit.com")
acc = Account("holger80", steem_instance=stm)
acc.get_voting_power()
95.37947158587963
stm
<Steem node=https://api.steemit.com, nobroadcast=False>
stm.get_blockchain_version()
'0.20.2'

New Features

delegation added to beempy

Delegation can be done by

beempy delegate -a <account> <amount> <to_account>

amount can be VESTS or STEEM and must be quoted with ".
Examples:

beempy delegate -a beembot "1 STEEM" holger80
beempy delegate -a beemboot "1000 VESTS" holger80

It is also possible to create steemconnect links by adding -l before delegate:

beempy -l delegate -a beembot "1 STEEM" holger80

This results in https://steemconnect.com/sign/delegate_vesting_shares?delegator=beembot&delegatee=holger80&vesting_shares=2021.090606+VESTS

Connection to HF20 testnet

The asset symbols were fixed for the HF20 testnet. It can be used by:

from beem import Steem
stm = Steem(node="https://testnet.steemitdev.com")
stm.chain_params["chain_id"] = "46d82ab7d8db682eb1959aed0ada039a6d49afa1602491f93dde9cac3e8e6c32"

Nodelist update

All nodes in nodelist were updated.

Unit tests

All unit tests were fixed. As non-appbase nodes are no longer available, all unit tests which uses non-appbase nodes were failing. This was fixed.

Greetings, great updates as usual.

One question, though, it seems appbase nodes supports both voting_manabar dict and the old last_vote_time and voting_power fields to keep the backward compability. Why beem was failing before this fix?

It failed as not all nodes have both dicts. Nodes running 0.19.12 have voting_power and nodes running 0.20.2 have only voting_manabar.

[emrebeyler]

I didn't try with all of them but https://api.steemit.com had both of them. (v0.20.2)

[holger80]

Only when using condenser api.
when using acc.steem.rpc.find_accounts({'accounts': ["holger80"]}, api="database") it is missing.

I see, thanks! :)
