Hmm, its not letting me attach the screenshot. If anyone wants it, email me.

Thanks for the report! Could you please attach the logs, from <workspace>/.metedata/.log?

Here is .metadata/.log

Is it really that short? It can't be right....

Please do this: open Eclipse, reproduce the problem and then go to window->preferences->erlang->report problem. Fill in some details, and "send" will create a file that I'd like to look at.

The related code has been rewritten recently. Are you willing to try the latest beta release (0.9.5)? As with any new release, it might have a few rough edges...

I updated to 0.9.5 and single step debugging just isn't working for me. I'm going to have to go back to 0.9.0. Sorry.

That's not good! What could be wrong? It works for me... I will look at it.

Regarding the variables, was there anything special about that value? (I suppose you know what value it should have had, approximately) Very large, or bitstrings, or anything less usually used.

I take that back, single stepping in 0.9.5 is working fine now. Must have been operator error.

The bug is now happening in 0.9.5 too. The term "Resp" is...

[{result, <<1,0,0,0>>}, {data, <<27,187,81,14,83,67,56,62>>}]


When I go back a frame the term appears in the variable list correctly (under the name "Response")

Does the source code have a macro there?

The crash is in some code that looks for a macro definition and it is code that we're not proud of. Ticket #611 aims exactly to rework this part of the code.

Is this a big problem for you, so that I try to fix it somehow right away? Or could it wait until next release in 3 weeks?

No macro in that function, but it is using a function that is included from another file. That file is automatically generated and has over 300 clauses.



Excerpts from file srpc_proto.erl:


-include("validate_request").
...
list_to_srpc_response(Req={_Key,Op}, Resp) ->
{RespType,_EncodeHint} = validate_request(Req),
...


Excerpts from file validate_request:

validate_request( {[systeminfo, macaddress], get}) -> {bin,none};
validate_request( {[systeminfo, numChannels], get}) -> {int,none};
validate_request( {[ids, Channel, on], call}) when is_integer(Channel) -> {none,none};
validate_request( {[ids, Channel, off], call}) when is_integer(Channel) -> {none,none};
validate_request( {[ids, Channel, autoconfigure], {call,Duration}}) when is_integer(Channel), is_integer(Duration) -> {none,autoconfigure};
... [300+ lines of this]
validate_request( {[config, account, Uid, gid], get}) when is_integer(Uid) -> {int,none}.

Aha, then I understand what is happening! Unfortunately I don't think I can give you a quick fix.

I will create a new ticket with the more specific issue and close this one. Will add you as watcher, so that you get notified.

see #720 instead

I should add I am in no hurry to have this fixed. Despite the bug I was still able to find and fix my problem and am now moving onto other tasks.

Ok. Thank you very much for the report!
