Initial sync broken #17

Closed Pttn closed 3 years ago

Pttn commented 5 years ago

New people came in the Discord server, and we just discovered that the wallet is just not syncing at all from scratch. To experience it, just move/delete temporarily your blockchain, no sync is happening. Tested in Debian 8, Debian 9, Windows 10. This is a serious issue that needs to be fixed as soon as possible as it will deter new people from using Riecoin. @clo-prime @cryptapus

That is weird, I am pretty sure that this worked fine from scratch in the past. If we use a bootstrap it syncs correctly though.

Fixing this is also the occasion to lower the activation threshold to like 75% as we can wait forever if we stay at 95%. Increase the window if needed but 95% is definitively too much in our case.

Another workaround is just to add 0.16.3 nodes from https://chainz.cryptoid.info/ric/#!network So it might be just that the current hard coded nodes are no longer active/reliable. If so we would need to ask people for more, reliable nodes.

I have just refreshed my dns seeds, perhaps they are getting stale. It would be helpful if more folks are able to run some dns seeds:

https://github.com/riecointeam/riecoin/blob/master/src/chainparams.cpp#L141

One could run nslookup riecoinseed1.cryptapus.org as an example.

Regarding lowering the activation, we can discuss on PR #19 after some examination.

Now it is syncing fine from scratch, though we should have more than only one (I assume that all the *.riecoin.org ones are dead). Someone provided a few node seeds, but I am still asking for DNS seeds in the Discord server.

cryptapus commented 5 years ago

Is anyone interested in running a DNS host like mine? We can add it to chainparams.

Pttn commented 5 years ago

XPoolX will try to set one. I also asked Ziiip and Guytp, not sure if they will.

Pttn commented 5 years ago

Unfortunately not much interest :| And XpoolX may need a week to set up one as he is pretty busy. If no ones shares any DNS seeds until May 5 we will make the 0.16.3.1 release anyway and add DNS seeds only in 0.16.3.2. Would you be in charge of the builds like for 0.16.3.0?

Pttn commented 5 years ago

Otherwise is there a way to force using the built-in node seeds if the DNS seeds are not available? As I at least have a list of additional node seeds. Even when your DNS was down, the already hard coded nodes were still active... Why was the wallet not connecting to them without having to use a bootstrap or doing addnode=... ?

cryptapus commented 5 years ago

As I recall, nodes will request one IP from a dnsseed on startup. Only if DNS is not available does it go to the hard-coded ones. Even then it is possible some of the nodes are rate-limited as it can be configured on a per-node basis. In the DNS case if a particular node on riecoinseed1.cryptapus.org round-robin is down it won't try again until a restart. Perhaps I have too many unreliable nodes, hence a second or third DNS provider would be helpful. I could add and setup a riecoinseed2 and riecoinseed3 however that would seem to be a bit too centralized in my hands, would prefer some external help here.

I can tag and build the release, I would encourage others to give it a try as it is reproducable. I recommend following the gitian guide here:

https://github.com/riecointeam/docs/blob/master/gitian-building.md

then building with something like:

./bin/gbuild --commit riecoin=${COMMIT} --url riecoin=${URL} ../riecoin/contrib/gitian-descriptors/gitian-linux.yml
(etc...)

(from https://github.com/riecointeam/docs/blob/master/gitian-building/gitian-building-manual.md#building-an-alternative-repository)

Pttn commented 5 years ago

Ok, I will give a try. Also maybe a second person will provide a DNS seed.

Pttn commented 5 years ago

Unfortunately nobody was able to set up a DNS seed yet. Adding some have to be postponed to 0.16.3.2 as the priority is to get everyone with the lower threshold. I will try to build today.

Pttn commented 3 years ago

Well, there does not seem to be much interest in providing nodes and DNS seeds... Hardcoding current nodes from for example CryptoID will be enough until we get more motivated people, I am closing this.
