[OpenSIPS-Users] python module

2023-03-30 Thread Alberto 
Hi,

I'm curious, since python_exec only accepts one extra parameter, how do you
guys pass multiple variables to a python function?

I personally do this:
$json(args) := "{}";
$json(args/param0) = "sdifuhsidfg";
$json(args/param1) = "asfagfgf";
$json(args/param2) = "asfergerghdf";
python_exec("python_my_fn", $json(args));

and then I restore the json object in the python function and use my
variables..

Thanks

Re: [OpenSIPS-Users] python module - python_exec() behaviour in opensips

2020-05-17 Thread Gordon Yeong 
hello Tomi,

yeah , when i test, I
1) put #!/usr/bin/python3 in the script, or
2) run "python3" for the interactive session

 yes, just read the
https://github.com/OpenSIPS/opensips/blob/master/modules/python/Makefile and
yeah, it's an ugly hack to have the system run python3 when python is
referred to.
 I had considered removing python 2.7 to which, after searching, it was not
a good idea for it would break the system.

As a quick work around, I went to the modules/python/Makefile and made the
following change:
-PYTHON=python3
+PYTHON=/usr/bin/python3

Compiled just fine.

Ran opensips with my config and I got more errors with my regexp which
tests out fine on python3's interactive terminal.
The regexp is in " rnRegExp = rnRegExp = re.compile(r'.*rn=\+6114(\d{2})');"

Got more error messages:

May 18 11:07:41 [58953] ERROR:python:python_handle_exception:
python_exec("get_rn"): Unhandled exception in the Python code:
May 18 11:07:41 [58953] ERROR:python:python_handle_exception:   TypeError:
an integer is required (got type str)
May 18 11:07:41 [58953] ERROR:python:python_handle_exception:
The above exception was the direct cause of the following exception:

May 18 11:07:41 [58953] ERROR:python:python_handle_exception:   Traceback
(most recent call last):
May 18 11:07:41 [58953] ERROR:python:python_handle_exception: File
"/home/gordon/opensips_proxy_source/modules/python/dumbat.py", line 61, in

return re.match(r'.*rn=\+6114(\d{2})', str(raw_enum_result) ).group(1);
May 18 11:07:41 [58953] ERROR:python:python_handle_exception:
SystemError:  returned a result with an error set   <--




I found out why.

 I took of the regexp and only issued a 'return "Hello World"' in my
function,get_rn().
 I kept getting the error, "TypeError: an integer is required (got type
str)".

Looked at
https://github.com/OpenSIPS/opensips/blob/master/modules/python/python_exec.c#L40-L41
and
it seems python_exec() will only ever return integers.
Thus, that's why it was barfing when I return non integer types.


I think we really need a function that executes python code and returns
data from the function just like what we have in the perl module,
perl_exec_func() (
https://opensips.org/html/docs/modules/1.5.x/perl.html#id293498).


So, guys, with this discovery, how do we run a python function  and return
its output to opensips config??

Re: [OpenSIPS-Users] python module - python_exec() behaviour in opensips

2020-05-16 Thread Gordon Yeong 
very interesting.
 I looked at the code in handler.py and adjusted my python class.

I ran opensips  (master branch) and found 2 issues:

1) python3 is not being run. How do i specify to opensips to use python 3?

May 17 15:45:46 [21373] Just done the enum query...The ru value is (
sip:service@192.168.136.133:5060)
Calling get_rn...

the rn code is [-1]
May 17 15:45:46 [21373] incoming reply



2) the type error seems to be coming from re.py . I will trace more later
but we need to make my opensips use python 3.


So, how do I specify python3 to be used in my opensips?

Gordon Yeong

Hi,
My second guess :)

Check this
https://github.com/OpenSIPS/opensips/blob/master/modules/python/handler.py 
<https://github.com/OpenSIPS/opensips/blob/master/modules/python/handler.py>

Differs from your version… Can these differences cause the failure?

The __init__ located inside class

And the mod_init located last in the script (does the order count for anything 
in python?)

Also called handler function always returns 1 not the init

Hi,

not sure has this nothing to do with the error but game to my eye trying to 
figure out what this bunch of code is really doing...

from python re docs:

Regular expressions use the backslash character ('\') to indicate special forms 
or to allow special characters to be used without invoking their special 
meaning. This collides with Python’s usage of the same character for the same 
purpose in string literals; for example, to match a literal backslash, one 
might have to write '' as the pattern string, because the regular 
expression must be \\, and each backslash must be expressed as \\ inside a 
regular Python string literal. Also, please note that any invalid escape 
sequences in Python’s usage of the backslash in string literals now generate a 
DeprecationWarning 
<https://docs.python.org/3/library/exceptions.html#DeprecationWarning> and in 
the future this will become a SyntaxError 
<https://docs.python.org/3/library/exceptions.html#SyntaxError>. This behaviour 
will happen even if it is a valid escape sequence for a regular expression.

The solution is to use Python’s raw string notation for regular expression 
patterns; backslashes are not handled in any special way in a string literal

Gordon,

 

Are you sure the TypeError is not occurring in mod_init? It looks like you are 
trying to do a print on a Class definition.

Subject: [OpenSIPS-Users] python module - python_exec() behaviour in opensips

 

hi guys,

 Using opensips 3.0 and python3 here.

 

 I have a script which parses a number in a string (r'.*rn=\+6114(\d{2})').

 

Script is as follows:

-- start ---

 

 

#!/usr/bin/python3
import re;
import pprint;


class test:

def get_rn():
rnRegExp = rnRegExp = re.compile(r'.*rn=\+6114(\d{2})');
doit = rnRegExp.match( 
str("sip:+61386947785;npdi;rn=+611...@tipt.ns.zippi.vocus.com 
<mailto:611...@tipt.ns.zippi.vocus.com>;user=phone"));

if doit:
pp = pprint.PrettyPrinter(indent=4);
return doit.group(1);
else:
return None;

result = test.get_rn();

if result is None:
print("Got no match\n");
else:
print("Result is " + result);

 

--- end --

 

In my opensips setup, I have the function above looking like this:

 

 start


from OpenSIPS import LM_ERR
import re;
import pprint;

def mod_init():
print("In mod_init, SIP MSG is : ");

2020-05-16 Thread Gordon Yeong 
Yeah I looked at that and ran my code on the python3 interpreter - it
worked.
Then i put it into a class - it worked.
 And then only did I put it (the class) to use in opensips..

Had there been an issue, python3 would have kicked and scream which it did
not.

 No issue with the regexp.
 Thank you

Re: [OpenSIPS-Users] python module - python_exec() behaviour in opensips

2020-05-16 Thread Tomi Hakkarainen 
Hi,

not sure has this nothing to do with the error but game to my eye trying to 
figure out what this bunch of code is really doing...

from python re docs:

Regular expressions use the backslash character ('\') to indicate special forms 
or to allow special characters to be used without invoking their special 
meaning. This collides with Python’s usage of the same character for the same 
purpose in string literals; for example, to match a literal backslash, one 
might have to write '' as the pattern string, because the regular 
expression must be \\, and each backslash must be expressed as \\ inside a 
regular Python string literal. Also, please note that any invalid escape 
sequences in Python’s usage of the backslash in string literals now generate a 
DeprecationWarning and in the future this will become a SyntaxError. This 
behaviour will happen even if it is a valid escape sequence for a regular 
expression.

The solution is to use Python’s raw string notation for regular expression 
patterns; backslashes are not handled in any special way in a string literal 
prefixed with 'r'. So r"\n" is a two-character string containing '\' and 'n', 
while "\n"is a one-character string containing a newline.

2020-05-15 Thread Gordon Yeong 
It's passed the init. If i did a print (LM_ERR) In the first line of
init(), it doesn't show that print.

If i  did a print (LM_ERR)a static string   in the get_rn()  before the
line that calls compile(), i noticed that it does print out.  And if i
tried to print a static string right after the compile() call,  it doesn't
print and it calls TypeError.

except TypeError:
 # Invalid input string

In my opensips config, I call the get_rn() function via python_exec() as below.

$var(rn_code)=python_exec("get_rn", $var(raw_string));

I'm facing an issue here because when I run the script by itself in a command 
line, it works.
 No "Error: Text Type" but when my opensips run, it keeps hitting a TypeError.
 I have even explicitly fed the " rn = get_rn.match(str(raw_enum_result));" 
with an explicit string (ie. I dont send use the value passed in from the 
argument BUT instead, just feed it an explicit string value) and yet the same 
issue occurs.

Does processing control belong directly to python3 when we call python_exec() 
or is there something funny going on here?

Re: [OpenSIPS-Users] python module - bug and questions

2017-04-21 Thread Maxim Sobolev 
Robert, what Bogdan says is essentially correct. The OpenSIPS itself is not
using any threads AFAIK, therefore python module code is kept as simple as
possible. Now back to the original question: we use quite a lot of python
code in our routing and some of the python modules that are running are
actually creating threads on their own and it appears to be pretty stable.
What OS / python version are you using? What could be different in our case
is that we link our OpenSIPS binary with pthreads always (which may or may
not be the case on your build), so there might be some vital threads
runtime infrastructure that is not getting initialized in your case.

Re: [OpenSIPS-Users] python module - bug and questions

2017-04-21 Thread Bogdan-Andrei Iancu 

Hi Robert,

The only question I can answer is 1) - OpenSIPS it is a multi-process 
application (and not using threads).


How the python module is design (from threading perspective), I do not 
know - maybe Maxim, the author of this module can help with this.

I am using openSIPS 2.2.3 on Ubuntu 16.04.2 LTS.

I am using the python module.  The python script called works fine 
when called from outside openSIPS and it works fine when called inside 
openSIPS, if it is triggered once at a time.


But if the python script is triggered twice by two phone calls or more 
or even one call after another in short order, then there are weird 
errors which show up in different places in the code like:


ERROR:python:python_handle_exception: #011TypeError: an integer is 
required


I am guessing the openSIP python module has some problem/s related to 
threading.


Questions:

1)I am guessing that OpenSIPS uses a multi-threaded architecture?

2)Is the python module meant to be a single thread? Or multi-threaded?

a.If it is meant to be single threaded then why use python library 
thread functions? Just use python library without multi-threaded stuff.


b.If it is meant to be multi-threaded then why is there only one call 
to PyThreadState_New and myThreadState is a global used everywhere?


i.I would think a thread per call to python_exec would make more sense 
and make the code easier to understand?


3)Also why is there no clean up code (PyThreadState_Clear, 
PyThreadState_Delete, Py_Finalize)?


a.I am guessing the idea is you do not need clean up, because it only 
happens when openSIPS is turned off.

[OpenSIPS-Users] python module - bug and questions

2017-04-19 Thread Mundkowsky, Robert 

Hi,

This email should likely go to your other dev forum, but I don't have access 
yet.

I am using openSIPS 2.2.3 on Ubuntu 16.04.2 LTS.

I am using the python module.  The python script called works fine when called 
from outside openSIPS and it works fine when called inside openSIPS, if it is 
triggered once at a time.

But if the python script is triggered twice by two phone calls or more or even 
one call after another in short order, then there are weird errors which show 
up in different places in the code like:

ERROR:python:python_handle_exception: #011TypeError: an integer is required

I am guessing the openSIP python module has some problem/s related to threading.


Questions:

1)  I am guessing that OpenSIPS uses a multi-threaded architecture?

2)  Is the python module meant to be a single thread? Or multi-threaded?

a.   If it is meant to be single threaded then why use python library 
thread functions? Just use python library without multi-threaded stuff.

b.  If it is meant to be multi-threaded then why is there only one call to 
PyThreadState_New and myThreadState is a global used everywhere?

   i.  I would 
think a thread per call to python_exec would make more sense and make the code 
easier to understand?

3)  Also why is there no clean up code (PyThreadState_Clear, 
PyThreadState_Delete, Py_Finalize)?

a.   I am guessing the idea is you do not need clean up, because it only 
happens when openSIPS is turned off.

Hi Duane,

The python module is not really obsolete, but rather an incomplete 
module - the developer (Maxim) uploading the module haven;t posted any 
documentation on it, so it is a kind of a black box (as usage).

Thanks for the response.

I need to customise the routing logic by making queries from another
database. Now that Python is out of the equation, what is the best choice of
implementing this customisation? Java  WeSIP don't seem to be good choices;
looks as if those are no longer maintained either. There remains only Perl,
I assume. I would appreciate any guide and advice.

Shaahin

Hi Shaahin,

If it's only DB queries check out the avpops modules. You can query any DB
and make decisions based on the results. If that's not enough, then I guess
Perl would be your best bet.

Hi Sam,

Unfortunately the developer of this module haven't uploaded a 
documentation file for it - I asked him several time to do it, but I 
cannot do more...

At least the module will stay in the trunk (will not be pushed to 
stable) until it gets proper docs.

Bogdan
