---------------------------------
Summary: hello_world core dumps when connection protocol misspelled
Key: QPID-5196
URL: https://issues.apache.org/jira/browse/QPID-5196
Project: Qpid
Issue Type: Bug
Components: C++ Client
Affects Versions: 0.25
Reporter: Chuck Rolke
With the advent of AMQP 1.0 users are required to specify a protocol as a
connection paramenter. If the user misspells the protocol name then hello_world
core dumps.
On Linux:
{noformat}
1 chug@FJELD ~/svn/qpid/b64/examples/messaging> ./hello_world localhost:5672
amq.topic "{protocol:amqp-1.0}"
terminate called after throwing an instance of 'qpid::Exception'
what(): Unsupported protocol: amqp-1.0
Aborted (core dumped)
{noformat}
On Windows:
{noformat}
hello_world localhost:5672 amq.topic "{protocol:ampq-1.0}"
==> Popup hello_world.exe
A problem caused the program to stop working correctly.
Please close the program. Choices: Close the program, or Debug the program
{noformat}
The Linux version at least prints out the text of the exception to give the
user a clue. On windows there is no hint of what went wrong and one must dive
into client library to find out if the desired protocol is loaded and if so
then what is its proper name.
I suggest that in hello_world.cpp the Connection constructor be moved to within
the try block. This, of course, means that the connection can't be closed in
the catch block.
Note that to get AMQP1.0 users actually want to use: {protocol:amqp1.0}
