[IntelMQ-dev] Help for fixing configuration of intelmq-manager 3.0.1-1

Hi, 

I do understand the separation of textual definition of a bot's parameters vs. the internal representation. In my problem case the regexp was in a class variable. If you refer to that variable using self.varnamehere it will show up among the bot's other instance parameters. So in my case this setting got inadvertently included among the ones that are iterated over when generating the JSON file for intelmq-manager. 

More on the latter: the docs on [ https://intelmq.readthedocs.io/en/latest/user/intelmq-manager.html#configuration | https://intelmq.readthedocs.io/en/latest/user/intelmq-manager.html#configuration ] speak about a "vars.js" file, however, according to the console "var.js" is searched for. Once this file is defined and contains the right ROOT variable setting, we are left with one TypeError: 

edge_map[path] is not iterable 

in the javascript console. Unfortunately, I am not sufficiently familiar with Javascript either to sort out what generates this error. 

Br, Mika

Hi, 

I think there's a misunderstanding between parameters - which can be set by users - and bots' internals.

Yes, I had a regexp in one of my bots although I don't understand why it should be prohibited to set these in a bot's parameter. It doesn't sound good to be limited to what can be serialized to JSON 


The requirement is that parameter's values can be set , in the runtime configuration or in the manager etc. It's impossible to express the instance of the re.Pattern class in runtime.yaml (and JSON).

- most advanced Python features get excluded based on this criterion.

IntelMQ's configuration is intentionally not Python code, but Text files. 

It's perfectly fine to compile regular expressions. 

If the expression comes from the user, i.e. it's a configuration parameter, you can do the compilation in init: [ https://github.com/certtools/intelmq/blob/7ebb8e16d821c372a44b077dd18a151c07f75807/intelmq/bots/collectors/microsoft/collector_interflow.py#L79 | https://github.com/certtools/intelmq/blob/7ebb8e16d821c372a44b077dd18a151c07f75807/intelmq/bots/collectors/microsoft/collector_interflow.py#L79 ] 


If it's not a parameter, but a constant value, the expression can be compiled earlier: [ https://github.com/certtools/intelmq/blob/7ebb8e16d821c372a44b077dd18a151c07f75807/intelmq/bots/parsers/cymru/parser_cap_program.py#L47 | https://github.com/certtools/intelmq/blob/7ebb8e16d821c372a44b077dd18a151c07f75807/intelmq/bots/parsers/cymru/parser_cap_program.py#L47 ] 

BQ_BEGIN

gets downloaded correctly. The only thing remaining is [ https://ourimq/intelmq/v1/api/positions | https://ourimq/intelmq/v1/api/positions ] accessed from within the Configuration tab:

 Apache returns the response happily with HTTP 200 status, the JSON corresponding to /etc/intelmq/manager/positions.conf is returned but an error still
appears in the browser tab:

"Failed to load config file properly"

 For the positions URL the Javascript console of the browser states two TypeError(s):

edge_map[path] is not iterable

and

app.network is null 

BQ_END
Sounds like a bug to me. I'd happy if someone with better knowledge of the manager's JS code can have a look. 

BQ_BEGIN

Also, an attempt to load [ https://ourimq/intelmq_manager/js/var.js | https://ourimq/intelmq_manager/js/var.js ] shows up but this file doesn't exist under /usr/share/intelmq_manager/html/js. A left-over from earlier versions? 

BQ_END


No, that's intentional: [ https://intelmq.readthedocs.io/en/latest/user/intelmq-manager.html#configuration | https://intelmq.readthedocs.io/en/latest/user/intelmq-manager.html#configuration ]

Hints welcome as before.

Br, Mika

Getting back to this anew. I've revised and rerevised all imaginable intelmq-manager configurations and problems remain. After debugging it looks like I still have issues
with intelmq-manager's Configuration tab, all other tabs are ok. From within the Configuration tab [ https://ourimq/intelmq/v1/api/bots | https://ourimq/intelmq/v1/api/bots ] is accessed which in turn invokes (under the hood)

sudo -u www-data -u intelmq intelmqctl --type json list bots

 This, I gather, is for generating the list of bots available on the right-hand side of the Configuration tab. Running this command from the command line gives:

Traceback (most recent call last):
  File "/usr/bin/intelmqctl", line 11, in <module>
    load_entry_point('intelmq==3.0.2', 'console_scripts', 'intelmqctl')()
  File "/usr/lib/python3/dist-packages/intelmq/bin/intelmqctl.py", line 1909, in main
    return x.run()
  File "/usr/lib/python3/dist-packages/intelmq/bin/intelmqctl.py", line 1051, in run
    print(json.dumps(results))
  File "/usr/lib/python3.8/json/__init__.py", line 231, in dumps
    return _default_encoder.encode(obj)
  File "/usr/lib/python3.8/json/encoder.py", line 199, in encode
    chunks = self.iterencode(o, _one_shot=True)
  File "/usr/lib/python3.8/json/encoder.py", line 257, in iterencode
    return _iterencode(o, 0)
  File "/usr/lib/python3.8/json/encoder.py", line 179, in default
    raise TypeError(f'Object of type {o.__class__.__name__} '
TypeError: Object of type Pattern is not JSON serializable


 I assume this is the reason why the Configuration tab in my instance is dysfunctional. 

BQ_END

Yes. 

BQ_BEGIN

Any hints? 

BQ_END

Do you have a custom bot which has a parameter that is of type
re.Pattern[0]? json.dumps fails serialzing this value. The solution is
to use a string as parameter type, then you are even able to configure
it :) You can compile the parameter's value at initialization.
