Support for stagenet

[stoffu]

This is a preliminary PR for the pending stagenet PR: monero-project/monero#3277

[moneroexamples]

Forgot to ask. What is stagenet? How is it different than testnet?

[stoffu]

This is the origin of the idea: monero-project/monero#3017

[moneroexamples]

thanks for fast reply. Is it already live?

[stoffu]

Yes. I'm hosting an explorer here: http://162.210.173.150:8083/ which is the same IP as one of the two seed nodes.

Please note that I've applied this pending PR monero-project/monero#3358 preemptively so that a series of successive hard forks from v2 to v7 can happen from height 32000 (which is only 300 blocks away as of now). So you'd need to build that PR if you want to try it.

[moneroexamples]

Thanks. Good to know. So this stagenet is equivalent to running testnet using latest release binaries: https://github.com/monero-project/monero/releases ?

[stoffu]

I'm not sure what you're asking. Testnet and stagenet use different seed nodes, port numbers, network IDs, etc. Also their fork heights are of course different. The idea is to keep stagenet as stable as mainnet so that people can experiment stuff on it without worrying about rollbacks which is very common on testnet.

[moneroexamples]

i'm taking about version number. current testnet is v8. so staging will be the same version as mainent (v6)?

[stoffu]

Currently it's v1, and the fork to v2 happens at 32000, followed by successive hardforks up to v7 at 37000.

[moneroexamples]

ah ok. thx for clarification.

Hi

Did you encounter Error: RPC error: failed to get output distribution error in cli monero wallet when trying to make txs in stagenet?

I'm trying to transfer from this stagenet wallet:

And cant seem to be able to make txs. Am at current monero master:

That's strange, I was able to make an outgoing transfer from that wallet: http://162.210.173.150:8083/tx/9c7a93b33e62e9cdbb0eee6f3be840a5b791a49f982afcd7863eff858768eac3

Receiving wallet:

[moneroexamples]

Thanks. I will investigate more. Maybe its something got mixed with my wallet and node.

[moneroexamples]

Was trying to debug this thing, and I'm hitting this exception:

THROW_WALLET_EXCEPTION_IF(segregation_fork_height - d.start_height >= d.distribution.size(), error::get_output_distribution, "Distribution size too small");

In wallet2.cpp: https://github.com/monero-project/monero/blob/master/src/wallet/wallet2.cpp#L5836

And it happens because segregation_fork_height is 1000000, d.start_height is 33000 and d.distribution.size() is 8317, for amount of 0, for an example tx.

It keeps happening from different wallets on different PCs. Do you know what is segregation fork and why its so high for stagenet?

[stoffu]

This fixes it: monero-project/monero#3473

[moneroexamples]

Thanks. Seems to be working with patch. Later I will do more checks, and if something, I will let you know.
