[rabbitmq-discuss] Broker Query Language (BQL) crashing

[Lynton Grice]

Hi Matthew,

I just tried you exact recommendations below using the latest default branch
of the server and the version of the BQL you specified, then I created the
EZ files etc (actually put the new versions of the server and BQL you
specified over the one in e FRESH "rabbit umbrella" download).....so that
was my exact config on Windows.

I followed the exact instructions again to install the BQL stuff, activated
the plugins and restarted the server and I still get an error ;-(

C:\soabox\erlang\rabbitmq-public-umbrella\rabbitmq-server\priv\plugins\rabbi
tmq-bql\scripts>bql.bat
BQL> select * from exchanges
{"init terminating in do_boot",{badarg,[{io,format,[<0.29.0>,"BQL execution
failed:~n
~s~n",[{undef,[{rabbit_misc,localnode,[rabbit]},{bql_applicator,appl
y_commands,2},{bql_server,handle_message,1},{bql_server,handle_call,3},{gen_
server,handle_msg,5},{proc_lib,init_p_do_apply,3}]}]]},{bql_client,run_comma
nd,
0},{bql_client,execute_shell,0},{bql_client,start,0},{init,start_it,1},{init
,start_em,1}]}}

Any ideas?

Lynton

Hi Lynton,

Sorry for the delay in getting back to you.

Right, that, it turns out, was an issue with quoting paths under Windows
which exists in 1.7.0 and has since been fixed. Thus rabbitmq-server
default branch no longer has this bug.

Under Windows? I suspect you may be the first!

Right, I have fixed the bug on the BQL plugin. Unfortunately it has yet
to be QA'd and so it's not on the default branch. At this point, because
of the above bug, the only possible solution under Windows is to run the
default branch of rabbitmq-server and the bab71e658da2 revision of BQL.
I believe that *should* work under Windows. I'm afraid that for reasons
of sanity, none of us develop here under Windows which explains,
although does not excuse, how these problems arose.

Please let us know how you get on.

Matthew
