Bitcoin / Armory / Re: Armory trying to create directories when apache invokes python script

Thanks for the reply. I'll give it a shot. To continue on I've set my perms to 777 but obviously this isn't ideal.

Bitcoin / Armory / Armory trying to create directories when apache invokes python script

on: April 04, 2015, 07:38:46 PM

I'm having an issue. Currently using a watch-only wallet on my Mac for localhost web development. Once ready I'm moving to digitalocean. I do not need the blockchain, just generating addresses. Following both Armory's github and this post:

https://bitcointalk.org/index.php?topic=56424.msg1492140#msg1492140

I can, via command line, retrieve an address (albeit with warnings, but nothing 2> /dev/null doesn't fix):

Code:

$ python /Users/me/repos/site/api/backend/armory/getNextAddress.py /Users/me/repos/site/api/backend/armory/armory_Z52GbQJB_.watchonly.wallet
(ERROR) ArmoryUtils.py:1172 - Error getting system details:
Traceback (most recent call last):
  File "/Users/me/repos/site/api/backend/armory/armoryengine/ArmoryUtils.py", line 1170, in <module>
    SystemSpecs = GetSystemDetails()
  File "/Users/me/repos/site/api/backend/armory/armoryengine/ArmoryUtils.py", line 1165, in GetSystemDetails
    out.HddAvailB = getHddSize(BTC_HOME_DIR)    / (1024**3)
  File "/Users/me/repos/site/api/backend/armory/armoryengine/ArmoryUtils.py", line 1162, in getHddSize
    s = os.statvfs(adir)
OSError: [Errno 2] No such file or directory: '/Users/me/Library/Application Support/Bitcoin/'
(ERROR) ArmoryUtils.py:1173 - Skipping.

However, when allowing apache to execute the same python script via:

Code:

$output = shell_exec('/usr/local/bin/python ../backend/armory/getNextAddress.py ../backend/armory/armory_Z52GbQJB_.watchonly.wallet');

I receive the following error in apache's error log:

Code:

==> /var/log/apache2/error_log <==

    from armoryengine.ALL import *

    mkdir(name, mode)
OSError: [Errno 13] Permission denied: '/Library/WebServer/Library'

I have tried:

adding '--datadir=pathtoarmory' to my getNextAddress.py script
absolute paths in my shell_exec call
symlinks in /var/www/html to avoid _www user from possibly needing permissions

I understand a "solution" would be to grant 777 access to /Library/WebServer, but why should I? It doesn't sound like a great answer. Why is Armory trying to make this directory? I see it does not create it when I run the same python script from command line. I set a watch for 0.1s on /Library/WebServer in case it was trying to be sneaky and create/delete like a ninja when run via command line, but no. No directory is ever created.

What's going on? How can I avoid this? All I need is the next deterministic address.

Thanks in advance.

Other / Beginners & Help / BFGMiner 3.6.0 buffer overflow

Hey. As a newb I can't actually post in the relevant thread so I'm posting here in hopes to get some visibility.

BFGMiner used to run rather nicely for me with no hiccups. Recently however I've been seeing my miner fail after a couple hours of running. I have debug on but the error always just barfs to the screen. I've put the output in pastebin to not clutter up the post:

Here is my cmd line run less username/passwords:

Code:

sudo /home/muh/repos/bfgminer/bfgminer --debuglog --log-file /home/muh/btc.log -o http://api.bitcoin.cz:8332 -u 1.worker1 -p x -o http://us1.eclipsemc.com:8337 -u 1 -p x -o http://us2.eclipsemc.com:8337 -u 1 -p x -o http://us3.eclipsemc.com:8337 -u 1 -p x

This is seriously disheartening. I've tried using cgminer but that doesn't even seem to recognize my BFL miner. I'd appreciate some input. Thanks in advance.
