Iam trying to remotely control the trace32 and trying to add commands from pyhton, in this process i have to set break point using python but i cannot set as its saying the function name is not defined (i have already flashed my hex and elf) other functions such as symbol name is working well
import lauterbach.trace32.rcl as t32
dbg = t32.autoconnect()
self = dbg.symbol.query_by_name(name='ComMainFunctionTx')
print(self)
bp = dbg.breakpoint.set(*"ComComMainFunctionTx ",**())
This is my output iam not understanding what to keep here for mapping
ComComMainFunctionTx P:0x801bacf0 930
Traceback (most recent call last):
File "c:\Users\Desktop\test hello.py", line 24, in <module>
bpt=dbg.breakpoint.set(*"ComComMainFunctionTx ",**())
TypeError: lauterbach.trace32.rcl._rc._breakpoint.BreakpointService.set() argument after ** must be a mapping, not tuple
update
this is what iam trying to do , iam adding dbg.go_return() to go to the next breakpoint but its throwing timedout error please help if i manually press go button its going to the next breakpoint in trace32 but giving bp.go() its giving timedout error
data=pd.read_csv("useR1.csv")

ARG = data['Arguments'].tolist()
for i in ARG:

I'm trying to run these lines of code in atom and python3.6 :

cf = CallFile(c, a)
cf.spool()

I would appreciate if you help me solving my problem.
thank you in advance
Looking at the source code for the validity check, it appears like the only check that could be catching you out is the one that verifies the spool directory. By default this is set to /var/spool/asterisk/outgoing but can be changed when you create the callfile:
cf = CallFile(c, a, spool_dir='/my/asterisk/spool/outgoing')
I am trying to do parallel ssh on servers. While doing this, i am getting "TypeError: 'NoneType' object is not iterable" this error. Kindly help.
My script is below
from pssh import ParallelSSHClient
from pssh.exceptions import AuthenticationException, UnknownHostException, ConnectionErrorException
def parallelsshjob():
client = ParallelSSHClient(['10.84.226.72','10.84.226.74'], user = 'root', password = 'XXX')
try:
output = client.run_command('racadm getsvctag', sudo=True)
print output
except (AuthenticationException, UnknownHostException, ConnectionErrorException):
pass
#print output
if __name__ == '__main__':
parallelsshjob()
And the Traceback is below
Traceback (most recent call last):
File "parallelssh.py", line 17, in <module>

File "parallelssh.py", line 10, in parallelsshjob
output = client.run_command('racadm getsvctag', sudo=True)
File "/Library/Python/2.7/site-packages/pssh/pssh_client.py", line 520, in run_command
raise ex
TypeError: 'NoneType' object is not iterable
Help me with the solution and also suggest me to use ssh-agent in this same script. Thanks in advance.
From reading the code and debugging a bit on my laptop, I believe the issue is that you don't have a file called ~/.ssh/config. It seems that parallel-ssh has a dependency on OpenSSH configuration, and this is the error you get when that file is missing.
read_openssh_config returns None here: https://github.com/pkittenis/parallel-ssh/blob/master/pssh/utils.py#L79
In turn, SSHClient.__init__ blows up when trying to unpack the values it expects to receive: https://github.com/pkittenis/parallel-ssh/blob/master/pssh/ssh_client.py#L97.
The fix is presumably to get some sort of OpenSSH config file in place, but I'm sorry to say I know nothing about that.
EDIT
After cleaning up some of parallel-ssh's exception handling, here's a better stack trace for the error:

This was seemingly a regression in the 0.92.0 version of the library which is now resolved in 0.92.1. Previous versions also work. OpenSSH config should not be a dependency.
To answer your SSH agent question, if there is one running and enabled in the user session it gets used automatically. If you would prefer to provide a private key programmatically can do the following
from pssh import ParallelSSHClient
from pssh.utils import load_private_key
pkey = load_private_key('my_private_key')
client = ParallelSSHClient(hosts, pkey=pkey)
Can also provide an agent with multiple keys programmatically, per below
from pssh import ParallelSSHClient
from pssh.utils import load_private_key
from pssh.agent import SSHAgent
pkey = load_private_key('my_private_key')
agent = SSHAgent()
agent.add_key(pkey)
client = ParallelSSHClient(hosts, agent=agent)
See documentation for more examples.
I'm writing a simple code in python 2.7 that is consuming messaging from an apache kafka topic. The code is the following:
from kafka import SimpleConsumer,KafkaClient
group = "my_group_test"
client = KafkaClient('localhost:9092')
cons = SimpleConsumer(client, group, "my_topic")
messages = cons.get_messages(count=1000,block=False)
But is raising this exception:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/lib/python2.7/dist-packages/kafka/consumer/simple.py", line 285, in get_messages
update_offset=False)

self._fetch()
File "/usr/local/lib/python2.7/dist-packages/kafka/consumer/simple.py", line 425, in _fetch
raise ConsumerFetchSizeTooSmall()
kafka.errors.ConsumerFetchSizeTooSmall
How could i modify this parameter (ConsumerFetchSize) in order to make this code work?
I found a solution,
using the parameter max_buffer_size in the SimpleConsumer.
The working code is:
#the size is adherent with my need but is totally arbitrary
cons = SimpleConsumer(client, group, "my_topic",max_buffer_size=9932768)
today I'm updated the elastic search from 1.6 to 2.1, because 1.6 is vulnerable version, after this update my website not working, give this error :

the code is this :
redis = Redis()
es = ElasticSearch(app.config['ELASTICSEARCH_URI'])
try:
es.create_index(app.config['ELASTICSEARCH_INDEX'])
except IndexAlreadyExistsError, e:
pass
where is wrong ? what is new on this new version ?
You're getting the following error: index_already_exists_exception
This means that you're trying to create an index that already exists. The second time you run your program you either need to delete your index first or create it only if it doesn't exist.
You have handled the exception using IndexAlreadyExistsError. Try using TransportError to handle the exception.
And you can also add a check like :
exist = es.indices.exists(index_name)
if not exist:
es.create_index(app.config['ELASTICSEARCH_INDEX'])
I'm testing ebaysdk Python library that lets you connect to ebay. Now I'm trying examples from: https://github.com/timotheus/ebaysdk-python/
So far I got stuck at this example:
from ebaysdk.shopping import Connection as Shopping
shopping = Shopping(domain="svcs.sandbox.ebay.com", config_file="ebay.yaml")
response = shopping.execute('FindPopularItems',
{'QueryKeywords': 'Python'})
print response.disct()
When I run it. It gives me this error:

Am I missing something here or it could be some kind of bug in library?
Do you have a config file? I had a lot of problems getting started with this SDK. To get the yaml config file to work, I had to specify the directory that it was in. So in your example, it would be:
shopping = Shopping(domain="svcs.sandbox.ebay.com", config_file=os.path.join(os.path.dirname(os.path.realpath(__file__)), 'ebay.yaml'))
You should also be able to specify debug=true in your Shopping() declaration as in Shopping(debug=True).
Make sure if you have not, to specify your APP_ID and other necessary values in the config file.
You have the wrong domain, it should be open.api.sandbox.ebay.com. See this page on the ebaysdk github.
