Permission issue in filequeue Windows

[MilindPurswani]

Hello @GP89,

I am facing some Permission issues in windows with FileQueue Library. Here is the error code:

PS > python .\syborg.py domain.com
Traceback (most recent call last):
  File ".\syborg.py", line 174, in <module>
    q = filequeue.FileQueue(maxsize=1000)
  File "C:\Python36\lib\site-packages\filequeue\filequeue.py", line 53, in __init__
    self._init_fds()
  File "C:\Python36\lib\site-packages\filequeue\filequeue.py", line 56, in _init_fds
    self._file_write = _file_open(self._temp_file.name, "wb")
PermissionError: [Errno 13] Permission denied: 'C:\\Users\\Yash\\AppData\\Local\\Temp\\tmpqnp_lbdw.queue'

Kindly check MilindPurswani/Syborg#6 for more info.

Thanks,

Hey, I see the issue. I'd never tested this on windows before. I should be able to get it sorted at some point in the next few days

@GP89, I was wondering. Do you have any similar library for stack? Like a FileStack or something?

[GP89]

Do you mean filequeue.LifoFileQueue? It's a swap in replacement for Queue.LifoQueue.

Just be aware that the to make it strictly always last in first out you need to initialise it with maxsize 0. I could address this issue just never got around to it

[MilindPurswani]

That sounds about right. But can you clear this one thing for me, if I make maxsize 0, wouldn't that be exactly same as Queue.LifoQueue ?

[GP89]

No sorry I think the parameter name is confusing. Maxsize refers to the size of an in memory buffer before it writes to disk. If maxsize is set to 0 everything will be written to disk. If the number of items constantly stays under maxsize then it will never need to write to disk and will be better performance wise, only if the number of items exceeds maxsize will it overflow and write to disk.

Hey @MilindPurswani
As of version 0.4.0 filequeue should now support windows!
Let me know if it works

Going to go ahead and close this as resolved
