Allow 'reaper' to continue processing if it gets invalid entries

[alexcpsec]

If there is an "invalid" http entry (returning something different from 200 or 302) or an "invalid" file entry (the file does not exist in the filesystem), it should log that it was unable to continue and carry on.

This is an issue specifically for file:// since #48 was done.

This has a dependency on #34

[alexcpsec]

Agree. Good point

I've investigated the issue a little, and seems like the stable version of grequests in pypi doesn't support the exception_handler parameter in map() to catch http exceptions.

There is a fix in spyoungtech/grequests#58 but it's not yet merged.

With the fix it's possible to do:

def exception_handler(request, exception):
    logger.error("Request %r failed: %r" % (request, exception))

inbound_responses = grequests.map(reqs, exception_handler=exception_handler)

I quickly tested it by removing the stable grequests and installing the patched version and it works as expected:

pip install https://github.com/rtdean/grequests/archive/0.3.0.zip

An example output:

2014-10-09 08:12:13,605 - combine.reaper - INFO - Fetching outbound URLs
2014-10-09 08:12:31,071 - combine.reaper - ERROR - Request <grequests.AsyncRequest object at 0x89f7fcc> failed: ConnectionError(MaxRetryError("HTTPSConnectionPool(host='zeustracker.abuseAAA.ch', port=443): Max retries exceeded with url: /blocklist.php?download=ipblocklistAAA (Caused by <class 'socket.error'>: [Errno 2] No such file or directory)",),)

Would it be a valid solution for you or would you like more to only have stable dependencies?

[alexcpsec]

I guess the answer really depends on:

• How difficult it would be to implement a solution with the stable dependencies?

• How long until the new grequests version is released?

  I saw you asked them when they expect to merge that, which is good. Also, I don't think our dependency management is very good right now (or it is too good, all '==" on requirements.txt ;) ).

My vote would be more leaning towards using the patched version and requiring the setup process to use it for now. But I have much less experience (i.e., none) on versioning management in Python then @technoskald , so I would defer to him.

This should do the trick:

pip install -e git+https://github.com/rtdean/grequests@0.3.0#egg=grequests

Pip freeze output:

$ pip freeze
CsvSchema==1.1.1
argparse==1.2.1
beautifulsoup4==4.3.2
feedparser==5.1.3
gevent==1.0.1
greenlet==0.4.2
-e git+https://github.com/rtdean/grequests@19239a34b00b8ac226b21f01b0fb55e869097fb7#egg=grequests-origin/0.3.0
netaddr==0.7.12
pygeoip==0.3.1
requests==2.3.0
wsgiref==0.1.2

[alexcpsec]

Sounds good to me. I'll subscribe the issue on grequests so we can know when it is done. :)

Any closing thoughts, @tecknoskald?

This would fix #32 also :)
