Problem Description

I'm trying to read all price from solana by each time I call the function. When I set solana_network with devnet, it was working perfect. However, when I try to use mainet, testnet, or pythnet, it can't work anymore.

Calling method

solana_network="mainnet" 
use_program = True

async def SolanaPythClientPriceFunction():
    async with PythClient(
        first_mapping_account_key=get_key(solana_network, "mapping"),
        program_key=get_key(solana_network, "program") if use_program else None,
    ) as c:
        await c.refresh_all_prices()

Debug Console Output

.....venv\Lib\site-packages\pythclient\pythclient.py", line 185, in _refresh_mapping_accounts
    raise exceptions.MissingAccountException(f"need account {key} but missing in getProgramAccount response")
pythclient.exceptions.MissingAccountException: need account AHtgzX45WTKfkPG53L6WYhGEXwQkN1BVknET3sVsLL8J but missing in getProgramAccount response

I checked the variables with debugger.

Until L180, everything works fine. Both key was correctly assigned values. But then, at L183,
m_data = account_json.get(AHtgzX45WTKfkPG53L6WYhGEXwQkN1BVknET3sVsLL8J )
it reads empty data.

Is this an error with mapping key? ( I checked with Pyth Network Website, the key is as same as here) Or with the method that I calling it?

Problem

Hardcoding mapping or program keys is not ideal. This is also hardcoded only for devnet.

Backgrournd

There are new dns records for all of these which should be looked up at runtime via a helper:

The following dns TXT records exist as authoritative references to these keys:

devnet-mapping-v2.pyth.network
devnet-program-v2.pyth.network
mainnet-mapping-v2.pyth.network
mainnet-program-v2.pyth.network
testnet-mapping-v2.pyth.network
testnet-program-v2.pyth.network

A shell example of looking them up:

$ for network in dev main test; do
    for type in mapping program; do
        key=$(host -t TXT ${network}net-${type}-v2.pyth.network | awk -F'[="]' '/(mapping|program)=/{print $3}')
        echo "$network $type key=$key"
    done
done

dev mapping key=BmA9Z6FjioHJPpjT39QazZyhDRUdZy2ezwx4GiDdE2u2
dev program key=gSbePebfvPy7tRqimPoVecS2UsBvYv46ynrzWocc92s
main mapping key=AHtgzX45WTKfkPG53L6WYhGEXwQkN1BVknET3sVsLL8J
main program key=FsJ3A3u2vn5cTVofAjvy6y5kwABJAqYWpe4975bi2epH
test mapping key=AFmdnt9ng1uVxqCmqwQJDAYC5cKTkw8gJKSM5PnzuF6z
test program key=8tfDNiaEyrV6Q1U4DEXrEigs9DoDtkugzFbybENEbCDz

Solution

Implement some helpers to look up these keys from dns. Have that be the way to solve this in the python client.

Pytest with pytest-timeout, pytest-socket

Hi, just wondering how I would:

• get a list of oracles available on pyth?
• query price date at historical points/ranges?

thank you

On a pull_request a github action will execute and do the following:

1. Run on ubuntu-latest (and we can also run it on Windows, MacOS for extended coverage)
2. Install multiple Python versions (3.7, 3.8, 3.9 etc)
3. Install python dependencies
4. Run flake8 on the code to find Python syntax errors or undefined names
5. Run Pytest
6. Upload artifact from workflow to shared data (optional)
