0.8.0 B4 ENGINE TypeError('expected string or buffer',)

[.maxx]

Hi guys,

get this error since B1.
Do you know what it means?

I'm on OSX 10.11.2 with Python 2.7.2

[shypike]

No idea.
Have you tried the latest Beta?
Or does it happen with the latest too?

[safihre]

(see the title of the post, so Beta4 also)

[shypike]

OK, missed that.
Under which circumstances does it occur?
SABnzbd is mainly developed on OSX (recently El Capitan) and I have never seen this issue.

FWIW: the error seems to producible from a RE in plain python, so that might be the cause in the wsgiserver2.py:

Good:

Code: Select all

>>> re.search("it", 'ditdat' )
<_sre.SRE_Match object at 0x7fbaaa8fe5e0>

Error:

Code: Select all

>>> re.search("it", ['ditdat'] )
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/re.py", line 146, in search
    return _compile(pattern, flags).search(string)
TypeError: expected string or buffer
>>>

I can't match this against the cherrypy/wsgiserver/wsgiserver2.py, as read_request_line is in different lines than reported by the OP.

I can see that line 705 isn't 100% crash-proof.
I'll investigate some more and at the least make a patch that will make the symptom go away.
Too bad that I do not have a scenario that reproduces it.
@.maxx: are there any specific circumstances under which this occurs?

@shypike

No I can't reproduce it. It occurs once a day.
Perhaps it is connected with the RSS feeds. I don't know.

I'm getting the same thing on 0.8.0Beta3 [0b6395f] with Python 2.7.3 (default, Mar 13 2014, 11:03:55) [GCC 4.7.2], Debian Wheezy.

Code: Select all

Will be fixed in the next release.
Any info about circumstances?

Have the same issue occur. Noticed it happens and i lose connection to SAB. Then it comes back with that error.

Was downloading a about 11 nzbs from usenet-crawler on OSX el capitan (most recent non-beta).

Also noticed I get a "Failed to send pushbullet message" warning as well. will investigate settings for that issue though.
