I should also point out that this is my first time building in a very long time (I think the last time was before you offered prebuilt Mac binaries) so in particular I have absolutely no evidence that there isn't something subtly borked in my build environment.

The OS X build process is mostly self-contained. Knock on wood and all but I've found that even the slightest hiccups cause Armory to not build properly. In other words, your environment's probably fine.

If you want to manually set your thread counts regardless, go inside BlockWriteBatcher.cpp and do the following:

1) comment out line 2004 to prevent thread adjustment
2) hardcode values in the BlockWriteBatcher ctor (line 112 for fullnode, 99 for supernode)

Could well be just chance since the behaviour before was clearly somewhat nondeterministric. But I did the above and it synced my wallets perfectly first time (and I hadn't managed to get a successfully sync at all so far up till now). If I get the chance tomorrow I'll nuke the databases and try again to confirm whether this is repeatable.

Just to confirm, only change I made was as you suggested:

Thanks. I'm sure you're right, but I might try nailing down the thread count anyway. (Probably not tonight though given how long it takes to rebuild on this slow machine. Is there no way of doing an incremental build on a Mac?)

This isn't the thread adjustment, it's failing to grab the block data or the data has expired before it got to process it. It's consistent with the symptoms of the issue I'm going after ATM so I'll have you wait for the fix to try this again. Right now I don't think there is anything else you can do about it.

If you want to manually set your thread counts regardless, go inside BlockWriteBatcher.cpp and do the following:

1) comment out line 2004 to prevent thread adjustment

Ah, interesting. In armorycpp.log, it looks like it got to around block 130,000 and then readjusted the number of threads. ~~No more~~ Only one more "finished applying" message after the thread readjust message - which takes it up to block 130,250 (which is before I was using bitcoin - so consistent with the wallets all showing zero balance).

Gimme the part of the log where it posts the timings after the scan is over. I want to see the last block it scanned.

Just reran it having removed the database and log files. Takes about 12 minutes to go through receiving headers, organizing blockchain and building databases - and then goes through the scan transactions phase in well under a minute (and ends up showing no transactions and 0.0 balance). I'll send you full logs of that run if you let me know the best way to get them to you.

EDIT: Block number displayed in the GUI is correct.

Ah, after several restarts of Armory it finally started scanning - made it most of the way there - now has transactions up to late 2014. There's virtually nothing interesting in armorylog.txt.

I get the following error at startup (which I presume is largely harmless?)

Code:

No errors building the database - but doesn't find any transactions and all wallet balances are 0.0

EDIT: Ah, OK, database appears to build OK judging by progress, but then scanning transactions seems to complete almost instantly (so evidently it actually failed - but didn't give an error).

New version out in ffreeze, please test away. There's a wealth of robustness changes and it should also be a bit faster. However no one at Armory has experienced the issues Carlton Banks and btcchris ran into, so most of these changes were speculative. It's possible these bugs will still be there partially or in full.

As usual, looking forward to your bug reports and logs, and again thank you for the time and effort you put in helping us to test things out =)

Have you made any big change re supernode? In the previous ffreeze it did not complete even with a week. In this version it took only a few hours to complete.

Quote

I made changes to some stuff that makes supernode faster (some weird opts I should have rolled but figured it could wait for fear it would be unstable). The other issue, with pulling block data and the object lifespan remains. It's a rare occurrence but common enough to trip certain setup quite often (2 out of my 3 testers T_T). I ended rolled the optimization with the stability changes (it didn't cost that much more to add the opts at that stage)

Now I'm also convinced that the code speeding up supernode is not responsible for the instability. That gives me room to add some more optimizations (again supernode only) without fear of making bugs more convoluted (and thus harder to isolated).

Not having a clue what the issue was, I ended up fixing what you were suffering from (which was a lot more obvious than the remaining issue) in an attempt to fix the bug they are experiencing. In grand scheme of things it doesn't matter what order I fix these, since I have to go after both anyways. In the current scope, it doesn't speak so good of me since I thought I was fixing one thing and got the other instead =P

Quote

I can now get the details of a random tx with "armoryd.py gettransaction txid". I guess this means the supernode in running properly?

Not really, that just means you are using supernode indeed (which is the only the DB format now that support random txhash resolution), but that doesn't mean supernode is working per se. What you need to do to test it is to add a random bitcoin address to a wallet and getledger on the wallet, which will display that random address history along with the rest.

You can also verify this in the UI by importing some publicly known private keys to a wallet (kind of an oxymoron I know) and verify they get imported quasi instantly and that their history shows up in the main ledger.

Ok this really is totally consistent behaviour. Tried not rebuilding the Db, just let it carry on from where it hits the (infinite?) loop. The headers get read again (implying the data structure for the headers wasn't committed to disk in the failed run), then it hits the same loop. I could try this with testnet I guess, but that's a fair amount of setup to confirm something so fundamental and consistent.

I've reproduced this issue and I'm on it. I've also got a clue on the other one in the process so I may get both by the next commit.

There is a difference to my setup, in that I'm using jessie instead of wheezy, but I don't think that's the source of the problem. I know, better to keep the setup the same, but it's a long story, and 93.1 works identically on jessie as it does on wheezy.

It should work on any setup as long as the compiler is doing its job really.

Can you get through with testnet?

Having trouble getting past this stage in the DB build:

Code:

-INFO  - 1433717171: (BlockUtils.cpp:1337) Looking for first unrecognized block

CPU cores hit the floor, that block never gets found.

Fresh DB folder? Is it maxing one core or all cores?
