Nico Maas updated PROTON-1465:
------------------------------
Description:
I use Qpid in Python to send files and do it this way:
{code}
from __future__ import print_function, unicode_literals
# qpid-proton
from proton import Message
from proton.utils import BlockingConnection
from proton.handlers import IncomingMessageHandler
activemq_channel = ""
activemq_connection = ""
activemq_session = ""
activemq_sender = ""
def mq_connect(ip, username, password):
global activemq_channel
global activemq_connection
global activemq_session
global activemq_sender
activemq_connection = BlockingConnection(username + ":" + password + "@" + ip
+ ":5672")
activemq_sender = activemq_connection.create_sender("file")
def mq_send(data):
global activemq_sender
#activemq_sender.send(Message(bytearray(data)))
activemq_sender.send(Message(durable=True,body=data))
def mq_close():
global activemq_connection
activemq_connection.close()
mq_connect(server_ip,'admin','admin')
for i in file_list:
data = open(i, 'rb')
mq_send(data.read())
data.close()
mq_close.close()
{code}
Sadly I could not send the files as bytearrays as I normally do.. but it should
work (Is there any better way to send binary files via proton?). However, on
random, following problem arises:
{code}
Traceback (most recent call last):
File "./send_activemq.py", line 323, in <module>
mq_send(data.read())
File "./send_activemq.py", line 271, in mq_send
activemq_sender.send(Message(body=data))

on_connection_remote_close
raise ConnectionClosed(event.connection)
proton.utils.ConnectionClosed: Connection x closed due to:
Condition('amqp:decode-error', 'Could not process AMQP commands')
{code}
ActiveMQ tells me following:
{code}
WARN | Transport Connection to: tcp://x:59158 failed:
org.apache.activemq.transport.amqp.AmqpProtocolException: Could not process
AMQP commands
WARN | Transport Connection to: tcp://x:55804 failed: java.io.EOFException
{code}
However, it always happens at random - without any clue on the file, size or
time..
What can I do? Python crashes at this point... So it is a blocker for me.
Thanks a lot for your help.
