Armory trying to create directories when apache invokes python script

[sftyw45af]

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):

    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)

    s = os.statvfs(adir)

(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 <==

    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.

Long story short, the "from armoryengine import *" line is tripping you up. I believe changing it to "from armoryengine.PyBtcWallet import PyBtcWallet" will fix your problem. I haven't tried it for myself, so you may need to experiment a bit.

Good luck.

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.

Don't mess with the permissions. This error means the auto path detection believes your blockchain data is in '/Users/me/Library/Application Support/Bitcoin/'. Apparently the user you are logged under does not have permissions to create that path.

The fix is to force your Bitcoin path with the --satoshi-datadir argument.
