[Pyst-users] ValueError: I/O operation on closed file

[Bernd S. <be...@bs...>]

I try to make asterisk wait for a call, answer some numbers, and Hangup.
I also want to run my python3 and pyst 0.8.0 script until the Hangup happens.

I do it in the following way:

After running connect() on asterisk.manager.Manager()
I use register.event() to register a callback for 'Hangup'

Then I change the dialplan for a spcific extension and context with
command("dialplan remove extension ...") and
command("dialplan add extension ...") for each line of

Answer()
Set(TIMEOUT(absolute)=%d)
Set(i=1)
While(True)
SayNumber(${i})
Wait(1)
Set(i=$[${i} + 1])
EndWhile()
Hangup()

Now I start message_loop()

And it works, sometimes without any error.
But sometimes after the Hangup callback is called I get the following  
exception:

Exception in thread Thread-3:
Traceback (most recent call last):
   File "/usr/lib/python3.7/threading.py", line 917, in _bootstrap_inner
     self.run()
   File "/usr/lib/python3.7/threading.py", line 865, in run
     self._target(*self._args, **self._kwargs)
   File "/usr/lib/python3/dist-packages/asterisk/manager.py", line  
293, in _receive_data
     for line in self._sock :
   File "/usr/lib/python3.7/socket.py", line 583, in readinto
     self._checkClosed()
ValueError: I/O operation on closed file.

And when I get the exception, in some cases even worse the python  
script hangs.

I already tested this 5 years before with python2 and an older pyst version.
And I believe the Exceptions occur now more often.

The good thing is, that before the python script hangs,
it has already communicated with asterisk. And asterisk works fine.
And so I made a brutal workaround, and kill my PID from the
"Hangup" callback afer waiting a short time.

But this workaround is ugly.

Do you think there is a design error in my algorithm ?
Do you have an idea, what I could try ?

This will exit the thread created by manager, not your main thread.
You generally shouldn't call exit in the callback functions, these are
called by the manager thread.

I'd set up a Queue between your callbacks and the main loop and wait for
an event on the queue in the main loop (where you're currently only
sleeping). Then when receiving that event you can safely exit the main
loop. I'm not sure calling ami.close in the callback is a good idea
either, you'd probably do that in the main loop, too, e.g.
(code completely untested)

from Queue import Queue

queue = Queue ()

...
ami = manager.Manager()
...

def handleEvent(event, ami):
    print ("Received event: %s" % event.name)
    if event.name == 'PeerlistComplete':
        ...
        queue.put("End")

...

item = queue.get ()
ami.close ()
sys.exit (0)

Hi, yes indeed that was the main issue.  I guess two threads were 
fighting for the responses.  Getting rid of that call and just looping 
forever around a sleep makes it always get all of the peers.  However 
now I can't seem to get the main loop to exit - the timeout alarm does 
it eventually (after five seconds), but the same code in the handler 
doesn't.  You can see that "printResult()" runs (the empty array shows 
in stdout), but the sys.exit(0) doesn't exit the parent thread I guess?

I get the impression that this library is really designed around making 
a multi-threaded daemon that just lives to process AMI events.  What I 
am looking for hardly requires that - a single threaded utility that 
just grabs some info and exits seems to be difficult to code :)  Can 
anyone supply an example that does something similar?  Here is what I 
have now:

#!/usr/bin/python

from asterisk import manager
import signal
import time
import sys

ip = "127.0.0.1"
user = "XXX"
passwd = "XXX"

peers = []

def handleEvent(event, ami):
     print ("Received event: %s" % event.name)

     if event.name == 'PeerlistComplete':
         printResults()
         ami.close()
         sys.exit(0)

     #print ("Received event Header: %s" % event.headers)

def eventTimeout(signum, frame):
     print "Timeout!"
     ami.close()
     sys.exit(1)

def printResults():
     print peers

ami = manager.Manager()
ami.connect(ip)
ami.login(user, passwd)
ami.register_event('PeerEntry', handleEvent)
ami.register_event('PeerlistComplete', handleEvent)

signal.signal(signal.SIGALRM, eventTimeout) # Sippeers tends to hang?
signal.alarm(5)

response = ami.send_action({'Action' : 'Sippeers'})
#ami.message_loop()
while(1):
     time.sleep(10)

-----

and the result:

root@jlpenha:/usr/local/bin# ./pypeers
Received event: PeerEntry
Received event: PeerEntry
Received event: PeerEntry
[snip]
Received event: PeerEntry
Received event: PeerlistComplete
[]
Timeout!


The "Timeout!" doesn't appear for five seconds...

Cheers,

j

You can debug this by looking with wireshark (or tcpdump) to the traffic
on port 5038. This should show you in what sequence you receive which
messages from asterisk.

Looking at your code: You should *not* call ami.message_loop explicitly
in your code. This is done behind the scenes by the ami implementation
of pyst. So you're probably creating a race condition there between your
call to ami.message_loop and the one that is called by a thread created
in the __init__ method of the Manager object.

So you really should leave all the processing to the thread created by
Manager and do something else (sleep?) in the main program.

[Pyst-users] Trouble with sippeers

[Jeff L. <je...@je...>]

Hello,

I started what I hoped to be a simple hack this morning and found pyst.  
I would like to use the asterisk AMI to pull a list of SIP peers and 
their status.  I am doing this today on a number of our customer 
asterisk instances using bourne shell and "asterisk -x "sip show 
peers'", then parsing the output, but this is turning out to be quite an 
intensive act to perform on the instance, thus the desire to use AMI.

After a few hours of surfing and playing around, I have ended up with this:

--------------

root@jlpenha:/usr/local/bin# more pypeers
#!/usr/bin/python

from asterisk import manager
import signal

ip = "127.0.0.1"
user = "XXX"
passwd = "XXX"

peers = []

def handleEvent(event, ami):
     print ("Received event: %s" % event.name)

     if event.name == 'PeerlistComplete':
         printResults()
         ami.close()

     #print ("Received event Header: %s" % event.headers)
     #add to peers[]

def eventTimeout(signum, frame):
     print "Timeout!"
     ami.close()

def printResults():
     print peers

ami = manager.Manager()
ami.connect(ip)
ami.login(user, passwd)
ami.register_event('PeerEntry', handleEvent)
ami.register_event('PeerlistComplete', handleEvent)

signal.signal(signal.SIGALRM, eventTimeout) # Sippeers tends to hang?
signal.alarm(5)

response = ami.send_action({'Action' : 'Sippeers'})
ami.message_loop()

print response

---------------

In testing I first noticed that about 30% of the time the script hangs, 
thus I implemented the signal timeout.  It seems to hang because I never 
get the PeerlistComplete event.  Is this a problem with asterisk not 
sending it or some kind of bug in pyst?

I next noticed that I rarely get the same number of peers:

--------

root@jlpenha:/usr/local/bin# ./pypeers | wc -l
27
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
68
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
71
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
67
root@jlpenha:/usr/local/bin# ./pypeers | wc -l
64

-------

This can't possibly be so difficult.  Surely someone has done what I am 
trying to do, though I haven't found any examples with lots of googling 
today.  Can anyone chime in?

Thanks!

Hi Italo,

What I am trying is to set the "returning" code, for example:

Dear All.

How i can get events for avery call attended. I need know id of a answered channel, so i can update the balance of the peer every x seconds.

In other words i need listen the asterisk.

[Pyst-users] AGI Return Codes using pyst

[Joel S. <jo...@jo...>]

Hi everybody.

This is my first post to the list, I am trying pyst and so far so good :)

One thing I don't understand:

No matter whatever I do, I always see in asterisk log:

AGI Script GetRegServerExt.py completed, returning 0

How can I change the returning code to something else?

This is my GetRegServerExt.py:


#!/usr/bin/env python
# coding: latin-1

import sys
import MySQLdb
from asterisk.agi import *

mysqlhost = "localhost"
mysqluser = "test"
mysqlpass = "test"
mysqldatabase = "test"
mysqlsock = "/var/run/mysqld/mysql.sock"

table = sys.argv[1]
extension = sys.argv[2]

myagi = AGI()
try:
    conn = MySQLdb.connect(host=mysqlhost, unix_socket=mysqlsock,
user=mysqluser, passwd=mysqlpass, db=mysqldatabase)
    conn.autocommit(True)
    cur = conn.cursor()
    query = "SELECT host,type,regserver FROM %s WHERE name='%s'" %
(table, extension)
    cur.execute(query)
    sqldata = cur.fetchall()
    cur.close()
    conn.close()
except (MySQLdb.OperationalError, MySQLdb.DataError,
MySQLdb.ProgrammingError), message:
    myagi.verbose("[AGI-ERROR] - MySQL Error %s: %s" % (message[0], message[1]))

if len(sqldata) ==  1:
    myagi.set_variable('host_extension', sqldata[0][0])
    myagi.set_variable('type_extension', sqldata[0][1])
    myagi.set_variable('reg_server', sqldata[0][2])
else:
    myagi.verbose("AGI Python: ERROR")


I have tried different ways of forced errors, but still return code is 0.

In fact, If I force MySQL errors (as wrong password, etc.), return code is 0

How can I send back to asterisk custom return codes so I know the real
result of the AGI execution?

Thank you all in advanced.

J.

Re: [Pyst-users] trouble with external command

[Michael B. <mbe...@gm...>]

thanks Daniel, that did the trick

I guess /usr/local/bin/ is not in the path used by agi's....  seems so odd
though that it would work if I ran it outside of an agi as the asterisk
user, I would think the paths would be the same since both run as the
asterisk user...

anyway, it works now, which is what's most important to me :)

thanks again!

[Pyst-users] trouble with external command

[Michael B. <mbe...@gm...>]

I've tried using both os.system as well as subprocess.call to invoke an
external command that is not working for me.  It has something to do with
the command I am trying to run, which is squeezy, a command line interface
for logitech media center.

I've been able to use os.system as well as subprocess.call successfully in
an agi using other commands, but not squeezy.

I can get squeezy to work using both os.system as well as subprocess.call
in an external python script if I copy out the revelant chunk of code, but
it will not work in an agi.  It works in an external python script if I run
it as either root or asterisk, so I don't think it is a permissions issue...

If I try to run squeezy in the agi using subprocess.call or
subprocess.check_call, the python agi dies right there

if I use os.system, the command still doesn't run as expected, but the agi
continues normally.

I don't know how to capture any useful output since the agi dies if I try
to use subprocess.check_call.

I don't see any of the regular python error messages in my asterisk CLI
output, the only output I see I generate myself with agi.verbose

How can I get to what is happening in the agi?  Can the python
errors/output be redirected somewhere I can see them?  I have been
debugging my issues using external python scripts to test, but in this case
my issue goes away in the external script...

I would appreciate any advice :)

thank you very much to all for the wonderful piece of software, it is so
nice to be able to use python for agi scripts!

[Pyst-users] Python asterisk libraries

[Antoine P. <an...@py...>]

Hello Ralf,

Today I've just learnt by chance (!) that you're trying to revive the 
pyst project. At
work we're still using pyst2, which is abandonware, but we decided some 
time ago to start
writing a replacement library, which we've just opened on PyPI and 
BitBucket:
https://pypi.python.org/pypi/obelus/
https://bitbucket.org/optiflowsrd/obelus

While the library is very young, still low-level, and unused in 
production, it also
comes with a number of improvements which are important to us:
- it's designed to be testable (and already has a non-trivial test 
suite)
- it's designed to be used in non-blocking applications, in a 
framework-agnostic way
- furthermore, its code base is bilingual (2.7 and 3.2+ compatible)

The reason why we decided to start a new project from scratch is that 
pyst2's original
structure is not really amenable to those improvements, and its lack of 
actual tests
made it difficult to perform major surgery while maintaining 
functionality.

I don't know how you feel about all this, but given the very small 
number of Python
developers interested in working on Asterisk bindings, perhaps it would 
be nice to
join forces.

(note that obelus' event-driven design wouldn't preclude it from being 
used in
traditional blocking-style code, if someone writes an adapter for that)

Regards

Antoine.

Ah, interesting detail, thanks.

You know that the patch is already in the latest Release 0.4.36?

Thanks for the feedback.

Re: [Pyst-users] How write FastAGI server?

[Vladimir <v....@gm...>]

Thanks, Ralf.

Running FastAGI in xinetd, set STDERR as file. And before running script
need set in dialplan variable AGISIGHUP=no, if this doesn't set we have
error in CLI

[Nov 28 05:49:59] ERROR[6625]: utils.c:1177 ast_carefulwrite: write()
returned error: Broken pipe

But I think running script XInetd no different from running script in
dialplan. This cloning the many similar processes.

I think found the best solution for Fastagi. Thanks Max Nesterov for patch:
https://sourceforge.net/tracker/index.php?func=detail&aid=3047290&group_id=76162&atid=546274

P.S: Sorry for my english

Interesting. I've never used FASTAGI myself, but thought that it is
basically the same protocol.

Hmm.

http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/AGI-variants.html
tells us that, yes, it basically is
and
http://www.asteriskdocs.org/en/3rd_Edition/asterisk-book-html-chunk/AGI-communication.html
seems to confirm this (except on channel hangup)

It looks to me like standard error is sent via the network connection.

Can you try redirecting standard error to somewhere else, there was a
recent patch that enabled this. You have to specify the stderr file that
you want to use explicitly when calling the constructor of AGI.

So in your AGI script instead of 

x = AGI ()

you specify something like

error_file = open ("/path/to/stderr/log", "w")
x = AGI (stderr = error_file)

This should do the trick of not sending stderr back to the asterisk
server.

Re: [Pyst-users] How write FastAGI server?

[Vladimir <v....@gm...>]

Thanks, the server works.
But script doesn't work. I tested in telnet

## test_agi.py

#!/home/tester/venv/aster/bin/python
# -*- coding: utf-8 -*-

import asterisk.agi

VERBOSE_LEVEL = 1

if __name__ == '__main__':

    agi = asterisk.agi.AGI()
    agi.verbose(u'Test message from FastAGI', VERBOSE_LEVEL)
    agi.hangup()

Since FastAGI simply forwards all the data from standard input and
standard output via a TCP socket, you should be able to drop your Pyst
Code into a call from inetd on the remote machine, e.g. in
/etc/inetd.conf you'd write something like

4711            stream  tcp     nowait  root /path/to/pyst/script

and then call this from asterisk with somethink like

exten => s,n,AGI(agi://192.168.0.2:4711)

In this way you leave the FastAGI network-specific code to inetd and you
should be able to use your local AGI Pyst code unmodified on the remote
server.

[Pyst-users] How write FastAGI server?

[Vladimir <v....@gm...>]

Hi everyone

Please show example FastAGI server on pyst.

Regards, Vladimir

[Pyst-users] Anyone still use this mailing list?

[Ryan C. <ry...@cu...>]

I'd like to edit this code to redial on a CHANUNAVAIL.  How can I detect
that in the agi script?

 

Thanks!
