MaidSafe Dev Update - March 2, 2017 - Test 12c


#142

David would any logs from people’s home vaults be of any use to the team?


#143

At the moment we are Ok, if there were issues we would try and collect some logs, but it all looks good for now.


#144

I had an idea for a simple monotonous (i.e. not absolute) network wide “clock.” The current value of this clock would be sent as one or two extra header fields within the regular SAFE network packets. Nodes would collect the opinion of their close nodes, but they would only distribute what their disjoint section as a whole thinks is the correct time. Basically, disjoint sections would aggregate the time information that is received and filtered by their members, and increase it once it’s plausible that most of the network is already in sync. There would never be a 100% correct value, but it would always be almost sure nobody on the network thinks it’s too much more or too much less than what we ourself think is the current value.

There’s a very badly explained version of this idea somewhere on this forum, but I’m not sure it’s worth reading it. Anyway, I started writing a simulator for it on my day off one or two weeks ago, but I never got to finish it. But it’s coming.


#145

hiya,

late joiner… been travelling so not able to join the fun til today…

running up 0.13.1 now, anything to watch out for?

wow…

bit of a struggle to join network, but the vault manfully fought the good fight and is now up and running…

+1 :+1: to this!
No more starting and stopping countless vaults.
Modeling human behavior :wink:

Got a bunch of warnings few hours ago, anything to worry about?

I had the same issue on March 3, a few hours after I started my vault. I believe it was caused by some network hiccup that my server had because I was not able to even ssh into it for a period of time (even though websites that I host there were still being served). After I was finally able to ssh into the server is when I noticed the error messages like yours. I eventually restarted the vault, and all has gone perfectly since then.

You can perhaps post your log for somebody to examine. You can do this from the bash command line with https://transfer.sh/ This is what I did. Perhaps between both of our logs, the team may be able to learn something.

To answer your question, I do not see anything bad happening on my vault. It’s happy and showing an estimated network size of 160.


#150

My vault recovered from this by itself - I didn’t restart and haven’t see these warnings for over 6h now.


#151

I hate to put a curse on the good ship 12c but it’s been amazingly solid so far. I have one vault running on Ubuntu in AWS and one on Windows at home which I take offline periodically and there’s not been a murmur of complaint from either. I wonder when it will be time to dial back the entrance criteria? Do we need to wait for datachains or will there be an interim stage for testing with slower nodes?


#152

@mav waiting patiently :wink:… no pressure!


#153

I suddenly have an estimated network size of 76 how can that be if Maidsafe have 100 droplets?


#154

My vault agrees. My Estimated network size is now 74

I just quickly went from “managing 10 client accounts” to “managing 18 client accounts”. Hey, I’m moving up in the world!


#155

steady drop from 150 in a short time.

#156

There is a bug in crust, not bad, we can see it and have been tracking this afternoon. Instead of logging a particular error (too many timers) it disconnects the node instead. We are able to sort the symptom easily enough, but are trying to find out why too many timers are established before committing to a fix. At the moment this is causing connection loss, but we are leaving it right now to analyse the network under this loss as it would be a weird attack to be able to do this, but it’s good info.

So not a big worry, however we do need to patch it.

#157

Are we kind of at a place now where we always have a community net going?

Looks like all the TEST 12’s so far have been allowing people to successfully run p2p networks on their own now.

Have we kind of passed the threshold where now there always is a p2p somewhat stable SAFE net running? Would be very cool!


#158

I doubt it will be worth it, this bug needs cleared really. I do not think it will take long to patch, maybe worth letting us do that and restart the testnet.


#159

Fix and explanation of the error in crust that we have suffered. Curious because if the network will be more active the bug would have remained latent. A good demonstration that the live tests are fundamental.


#161

Is there a measure for data retention.
ie. 12c vs pre 12 series vaults from home?


#162

Can’t wait to get home tonight and have a muck around.
