ArmoryDB doesn't scan blocks, no errors in log

[carcinogen]

I am running a synced full node and the latest 96.5 version of Armory, having deleted the old database files and performed a clean reinstall.

Originally I had a conflict on port 9001 which I believe has something to do with either Quickbooks networking or Intel drivers.

I then tried to run ArmoryDB using the following argument:

Code:

ArmoryDB.exe --fcgi-port=15000 --satoshi-datadir="F:\Bitcoin" --datadir="C:\Users\chris\AppData\Roaming\Armory"

Per the log, ArmoryDB stops doing anything on "Enabling zero-conf tracking" for hours.

Log below:

I tried running armoryqt --armorydb-port=15000 --force-fcgi on top of the ArmoryDB but get "Armory failed to spawn the DB!" error.

I also tried running the same ArmoryQT command without ArmoryDB running, which produces the same result.

Any ideas?

[carcinogen]

OK, I discovered that the satoshi-datadir is actually Bitcoin\blocks\blocks for some reason. After setting this, ArmoryDB starts to parse but throws the following error every couple blocks:

Code:

-ERROR - 11:27:59.234: (e:\users\goat\code\armory3\cppforswig\noderpc.cpp:114) RPC connection test error: invalid object encapsulation

Is this an error to be concerned about?

[goatpig]

Failed to talk to Core RPC, useful but not crucial. Are you running Core with --server=1?

[carcinogen]

Failed to talk to Core RPC, useful but not crucial. Are you running Core with --server=1?

I added this to the config, and the RPC error went away.

IN the meantime, I deleted and redownloaded the entire blockchain with the correct pathing and cannot get ArmoryQt to play nice with ArmoryDB.

The problem stems from my Windows 10 installation which already has an Intel service listening on 9001.

I initialize armorydb.exe --fcgi-port=9002 --satoshi-datadir="F:\Bitcoin" and it appears to sync up properly.

Then I run armoryqt.exe --armorydb-port=9002 --satoshi-datadir="F:\Bitcoin" and it fails to go online with the following log:

I have also tried supplying "F:\Bitcoin\blocks" as the satoshi datadir with the same result.

I have also attempted to run Armory by itself without arguments so that it spawns the DB, but the program simply freezes and writes infinitely to armorycpplog.txt the following error:

Code:

-ERROR - 17:31:11.625: (e:\users\goat\code\armory3\cppforswig\stringsockets.cpp:351) FcgiSocket::writeAndRead FcgiError: unexpected fcgi header version

I assume this has something to do with port 9001 being unavailable because no such error appears when the term --armorydb-port=9002 is supplied.

[goatpig]

Then I run armoryqt.exe --armorydb-port=9002 --satoshi-datadir="F:\Bitcoin" and it fails to go online with the following log:

Sounds like python/swig shenanigans. Try

Code:

armoryqt.exe --armorydb-port="9002" --satoshi-datadir="F:\Bitcoin"

[carcinogen]

Tried this, unfortunately the same result occurred.

[goatpig]

For some reason, python is refusing to read the port as a string.

https://github.com/goatpig/BitcoinArmory/blob/master/ArmoryQt.py#L1796

Forcing str() there may be of help.

I have also attempted to run Armory by itself without arguments so that it spawns the DB, but the program simply freezes and writes infinitely to armorycpplog.txt the following error:

Code:

-ERROR - 17:31:11.625: (e:\users\goat\code\armory3\cppforswig\stringsockets.cpp:351) FcgiSocket::writeAndRead FcgiError: unexpected fcgi header version

I assume this has something to do with port 9001 being unavailable because no such error appears when the term --armorydb-port=9002 is supplied.

I'm getting the same program freeze while starting Armory with the same error and rapidly growing armorycpplog.txt file.

Everything worked fine the last time I ran Armory about a month ago so I assume some windows update caused the issue.

Port 9001 is also being shown used by some unknown windows system process on my pc.

Also getting the same python refusing to read the string error when using the --armorydb-port= cmd line option.

Is there a work around for this or can it only be fixed with an Armory update?

[goatpig]

Try setting the port through armoryqt.conf (for ArmoryQt) and armorydb.conf (for ArmoryDB)

[aneutronic]

Thanks for the quick reply!

I get the same results and errors whether port is specified on cmd line or config files.

Code:

It looks like the same "TypeError:" on line 1796 carcinogen is getting.

The problem stems from my Windows 10 installation which already has an Intel service listening on 9001.

I initialize armorydb.exe --fcgi-port=9002 --satoshi-datadir="F:\Bitcoin" and it appears to sync up properly.

Then I run armoryqt.exe --armorydb-port=9002 --satoshi-datadir="F:\Bitcoin" and it fails to go online with the following log:

The problem with changing port number is only in armoryqt.exe as I can run armorydb.exe with a port number specified on the cmd line and it appears to work ok.

[goatpig]

Have you tried putting the port in quotes?

[aneutronic]

yes sir, with or without quotes makes no difference.

[goatpig]

Well then there's a final trick, but it's worth trying. I'm going to guess you're on Windows, which is the only OS on which changing the Python code files is tricky.

As I said it's tricky but not impossible. Python code isn't compiled per se, it's interpreted. In the windows package, Armory bundles the Python interpreter along with the binary source for each python code file. This is so that Windows users can just run one executable. This executable starts the Python interpreter, and then points it to the Python code files in a zip archive: library.zip.

If you change a code in that library, it should be reflected in your setup. The idea is therefor to change hardcoded port in ArmoryUtils.py and replace that file in the code library zip archive. This would be a text file and not a binary file, so I'm not 100% sure that trick will work, but Python typically converts text files to binary files on the fly at import time so it should work.

You would need to change the port value at this line:

https://github.com/goatpig/BitcoinArmory/blob/master/armoryengine/ArmoryUtils.py#L88

Then copy the modified file in the zip archive (it's in the armoryengine folder), and delete the old file (ArmoryUtils.pyc). Your file is a .py (text), the file you're getting rid of is in binary (.pyc). Python should do the conversion for you next time your run Armory.

[aneutronic]

Yes, I'm using windows 10 and nice trick! Modifying the AmoryUtils.py does work to change the port number to 15000 but armoryqt still freezes, won't start armorydb and I still get the same fcgi error in the rapidly growing armorycpplog.txt.

Any ideas on what else could be tripping the fcgi error? The only thing that changed on my pc since the last successful run was windows updates.

[goatpig]

1) Check port 15000 isn't in use.

2) Check ArmoryQt is actually trying to connect to localhost:15000

3) Start ArmoryDB manually if you have to, give it the proper port.

[jaume.signin]

I also get a fcgi error. Mine is a bit different.

-ERROR - 15:36:48: (StringSockets.cpp:351) FcgiSocket::writeAndRead FcgiError: unknown fcgi header request byte

Now I'll try with "rebuild".

1) Check port 15000 isn't in use.
2) Check ArmoryQt is actually trying to connect to localhost:15000
3) Start ArmoryDB manually if you have to, give it the proper port.

1) Yes, did that using tcpview.

2) ArmoryQT never connects to 15000 even when running properly, only 8223.
At least that's what tcpview showed.

3) Tried this again and it works only if you start armorydb manually first then launch armoryqt.
I haven't tried any transactions yet but everything looks normal.
I guess it's ok as a temporary solution but still would like to know why armoryqt freezes and won't start armorydb on it's own.
Also I noticed that if you launch armoryqt first then start armorydb manually it won't connect to the db and tcpview fills up with system processes using port 9001.

https://github.com/goatpig/BitcoinArmory/blob/master/ArmoryQt.py#L1795

It runs this check on port 9001 instead of your custom one. Possibly the value hasn't been reflect in ArmoryQt.py cause it's hardcoded in ArmoryUtils.py and the compiler is that dumb?
