windows drive letter not working as store path

[littleskunk]

My config:

  "storage": {
    "C:\\Storj": {
      "use_folder_tree": false, 
      "limit": "1G"
    }
  }, 

I also tried:

  "storage": {
    "C:/Storj": {
      "use_folder_tree": false, 
      "limit": "1G"
    }
  }, 

Both configs don't work. Files are stored in %userprofile%/Storj in both cases.

I set the limit to 100G for a better logoutput. Both configs give me the following output:

2016-02-22 22:28:11,845 WARNING storjnode.storage.manager 62: Invalid storage limit for C:\Users\jensh_000\Storj: 107374182400 > available 85214018904. Using available 85214018904!

This is the code that gets the path. Why it doesn't use this util function I don't remember, there may be a reason, or it may just be an oversight on my part.

I moved many things from storjnode to storjlib, and in the future storjnode will need to be changed to use storjlib for that code (this will slim down storjnode a lot).

This is one of the functions I moved and changed here. I will backport the changes, but will need someone with a windows machine to confirm it works on windows as well.

[F483]

It seems my above analysis is incorrect. I already did this a while ago here and the function is being used correctly here.

@robertsdotpm @littleskunk could one of you debug what’s wrong with this on windows? I currently do not have access to (or am used to using) windows.

[littleskunk]

def full_path(path):
    """Resolves, sym links, rel paths, variables, and tilds to abs paths."""
    print path
    prefix = "/" if path.startswith("/") else ""
    print prefix
    normalized = prefix + os.path.join(*re.findall(r"[^\\|^/]+", path))
    print normalized
    print os.path.abspath(os.path.expandvars(os.path.expanduser(normalized)))
    return os.path.abspath(os.path.expandvars(os.path.expanduser(normalized)))

Output:

path = C:\Python27\Scripts\Storj
prefix = 
normalized = C:Python27\Scripts\Storj
return = C:\Python27\Scripts\Python27\Scripts\Storj

So the full_path function is correct on windows? If so it must have something to do with how the config is been given.

What were the exact arguments given to storjnode and the exact config used?

[littleskunk]

I see 2 problems. At the moment the config returns a wrong path. That is not the fault of full_path. We should find and fix that bug first but it looks like the return value of full_path as a second bug.

[littleskunk]

My config:

  "storage": {
    "C:/Storj": {
      "use_folder_tree": false, 
      "limit": "100G"
    }
  },

[F483]

Out of curiosity what does full_path return for "C:/Storj" on windows? Maybe there is some case I didn't see.

[littleskunk]

I am running python for windows (C:\Python27\Scripts): python storjnode --wallet=[...] --debug farm return = C:\Python27\Scripts\Python27\Scripts\Storj

[F483]

That means it should be loading from the default config path and I assume the config you posted above is that.

@littleskunk what output do you get for storjnode --wallet=[...] --debug cfg_get_current?

[littleskunk]

Server down at the moment. I will debug some more tomorrow starting with https://github.com/Storj/storjnode/blob/develop/storjnode/api.py#L67

cfg_get_current returns my config file %userprofile%.storj\cfg.json.

Found the bug. https://github.com/Storj/storjnode/blame/develop/storjnode/util.py#L118

Setup is called 2 times. The first call returns the wrong path that is the input for the second call.
