Well, today is totally lost. Between dealing with investor support issues I have to spend hours fiddling with MGW server.

I have way too much coding to do to be stuck doing MGW server maintenance!

So far the issues have not been related to MGW itself, server out of RAM, new versions, shellshock, test versions crashing and messing up the cache, etc.

As of next weekend, I will formally stop running MGW servers. Until the production servers are running, there wont be any MGW servers.

I suggest to withdraw all the MGW assets ASAP. if they get stuck after I shutdown the MGW on my dev servers, it could take a while for me to figure out how to properly to manual withdraws. I need to code for 14 to 20 hours at a stretch and I cannot be monitoring people's deposit/withdraws that are not appearing after 17 blocks. So if you do not withdraw before the weekend, the funds will be safe but inaccessible for some weeks.

James

I still don't understand why you don't get a few free or cheap VPS's to run the MGW servers on so they won't be affected by your developing.

But, whatevs.

there are two different affectings of my developing
even if it is on different hardware, I have to do three separate patching of shellshock, I have to make sure the blockchains are synced, I have to respond to every PM for any tx that is not immediately completed
I have been doing this for months

Now I need to write some thousands of lines of code.

I have two speeds, the slow 100 lines per day when I am being interrupted all the time. this is ok if I am debugging and not much code is needed. Then there is the 1000 lines per day of coding to create large new functionality. To do this I need 12+ hours of uninterrupted concentration.

Having a VPS does not solve the big problem.
Having a production server team does

Lost internet, back now.

my internet connection is very unreliable. often before I can get all three MGW servers properly setup, i lose connection and have to start over. what should take a few minutes can take half hour or more.

I know, I should get a better internet connection. I tried that and things went from a bad internet connection to horrible, I switched back to the bad internet connection.

when I am coding, the bad internet connection is annoying, but it is not such a big deal. when I have to fiddle with servers, it is quite a bit deal.

anyway, the third server finally rebuilt the cache (thanks to my trick of copying an ignorelist.BTC from another server), but the NXT core was stuck and not getting new blocks, so I had to shutdown the MGW, kickstart the NXT and restart the MGW.

now it is about 6000 BTC blocks from catching up and once it does it should sync with the other two and all the pending withdraws should complete.

James

P.S. Until you see the withdraws complete, it is not done, please do not PM me about tx status. this is still a weekend right? that is the time I count on to not have to worry about MGW so I can do the uninterrupted coding.

Hey James, i know you have a lot of work. But if someone could check my withdrawal, it has been not processed since the 26th.

http://87.230.14.1/nxt/nxt.cgi?action=2000&tra=10729876664729894841

If you can't process it, please send me the asset back !

Thanks.

2 of the 3 servers are caught up, but the third one is sputtering. Ive been up 30+ hrs and I just cant stay up longer to make sure the third server catches up properly.

Hopefully in some hours it will be working, but it is still far from done

A lot of people have pending transactions.  Once the servers are synced, the transactions should go through.  It'll probably be pretty soon.

the server with the problems is caught up, but the third server hit a fork did a restart and is lagging
it is within 1000 blocks, so hopefully soon

However with all the withdraws pending, it exceeded the max allowed
so I had to make a new version that increased this max

which then overflowed a different buffer, so I had to do another iteration to fix that

then a scenario that is rare, but with the large number of pending tx becomes more likely appeared. The internal order of the tx was inconsistent between the servers. This created the same outputs but in a different order and so the servers didnt sync. I believe this happened due to a timing race condition between when a BTC block comes in vs. when a NXT block comes in, especially if a NXT block is a longer than a BTC block. And this has to happen so that on one server it goes in one order, but on another the different order. So, the same money result but different order in the transaction and the servers dont match

to fix this I just sort the outputs in descending order of amounts

I made a few other small changes, but one of them seems to cause a crash and restart so I reverted it.

Now 2 of 3 servers are running the version with a much bigger buffer, sorted outputs and what I hope are a few bug fixes and not new bugs.

If all goes well in a few hours, it should be caught up, but so far nothing has gone well so until I post that the MGW is caught up, it is not.

Good news and bad news.
All three servers caught up and so all the bad data in the cache has been fixed. However, they still dont sync as the inputs are coming in a different order.

I also realized that sorting the outputs by amount could lead to different order on different servers if there are different withdraws of the same amount and the sort also isnt deterministic. Since it is a one level sort, I am not sure how it will end up on the different servers.

To solve both issues I now sort both inputs and outputs based on strings made from the txid.vout or destaddr, since the txid.vout and destaddrs are unique there is no worries about different orders when the primary keys are the same

Since these are rather big changes, I am testing on the BTCD side of things and if all goes well (definitely not the recent trend), within a few hours I will have confirmation that the new input + output sorting is working.

However, along the way I might have introduced a bug in the sync networking code as the crc's for the batchwidthdraws are always 0 for the other servers.

Anyway, step by step progress. First get all three servers to generate sorted batch withdraws, then get the network sync fixed (if it is actually broken), then restart for BTC.

Unfortunately, with the times measured in hours for each iteration (the code that I tried to speed things up caused core dumps) I doubt the withdraws for some hours yet.

If there is any good news in any of this, it is that new cases of withdraw conditions created by the mass withdraws has actually found the first MGW bugs found in a long time and having them fixed now is definitely better than after it was in production.

James

tl:dr wait until I say MGW is all caught up, until then no withdraws will happen

Does that mean mgwBTC is not caught up?

I believe mgwBTC withdrawals are still pending.

Two of my mgwBTC withdrawals are now delayed by 208 hours (8 days 16 hours). Transaction IDs: 10698833842468636419 and 3709520954231419634.

Edit: updated delays

I still haven't received my BTC.

Doge isn't active yet.  I believe Team Starbuck is going to be responsible for DOGE when the production servers come online in a couple days.
