osquery can't close win pipe

[blessedvictim]

After any query on del of SpawnInstance I get an ignored exception
Exception ignored in <bound method SpawnInstance.__del__ of <osquery.management.SpawnInstance object at 0x021854F0>> pywintypes.error: (1, 'DicsonnectNamedPipe', 'Incorrect function.')
my script:
import osquery instance = osquery.SpawnInstance() instance.open() instance.client.query("<some query>")
Now i use some dirty "hack" as after
instance.client.query("<some query>")
i do:
instance.connection=None
My machine os:
Windows 7x64

This issue remains on version 3.0.6. I used del (calling __del__ internally) to make a more reasonable pipe closing, since there's no close function.

>>> import osquery
>>> instance = osquery.SpawnInstance()
>>> instance.open()
>>> del instance
Exception ignored in: <function SpawnInstance.__del__ at 0x000000D3ABF62678>
Traceback (most recent call last):

This still happens in 3.0.7 (latest version from pip) on win 10

Problem disappears when using outhex@19691b9 - this fix

@hotab This fix worked for me, too.
Thanks for pointing out.

I'm using win10, with:

• osquery==3.0.7
• pywin32==306
• pywin32-ctypes==0.2.2
