Music cont out proxy

[uahic]

New neuron type to support forwarding continuous values via the MUSIC continuous output port.

Notes:

• A description how it works can be found in the header file.
• An example is provided in the /pynest/examples/music_cont_out_proxy_example directory
• The code is not written to support the MusicManager class yet. If this is desired we need to discuss implementation details (how to encapsulate port buffers, etc.).
• The max_buffered property for the port cannot be set by the user in the current state.
• It might be desirable to clean up the code in the future

Hello @uahic ,

TravisCI is complaining about the formatting of the code. Please follow the instructions on our developer space on formatting the code with clang-format.

[uahic]

@tammoippen I really did all the checks now and I used some vim plugins for clang-format but also did it via command line. Travis still complaints because of some line breaks but they are enforced by the screen width of 80 which is set in the .clang-format file. I am a bit lost ...

[tammoippen]

Hello @uahic,
The formatting of some committed files does not confirm to our coding guidelines. Please, closely follow the instructions you find there, especially the Tooling section gives information on automated formatting with clang-format and local testing of the coding guidelines. The automated formatting is obligatory for accepting PR; please ensure to use clang-format version 3.6, as the formatting varies with different versions. NEST provides a .clang-format file in its sources.

@weidel-p Can you please look into this PR? Thank you.

I found a bug in my model in case when the ports are not correctly mapped, a patch will follow ASAP

[uahic]

Update: the error seems to originate from a message input port (segfault). The segfault actually happens in the music lib if port names in the music conf and published names in the scripts does not match, regardless of the model

long_t → long

@jougs Changed long_t and double_t to the standard type names

👍 music_cont_out_proxy_example successfully tested with music v1.1.15 ! There is no dependency on the custom music branch any more.

@uahic
In the course of setting up automated MUSIC tests for NEST (PR #471) a SLI version of your music_cont_out_proxy_example is required. It would be fantastic if you could provide a SLI example.

[uahic]

@gtrensch
I am willing to provide the SLI example/test case, however before digging deeper into SLI (which I have never worked with), I need a little hint from you: How do I add a custom neuron to the SLI models dict? Actually the music_cont_out_proxy is already in the modelsmodule ( within models folder) and I dont see another place where models need to be registered. Does the model miss any declaration/method or is SLI unhappy with the status dictionary arguments? Because SLI tells me that music_cont_out_proxy is unknown, whereas music_cont_in_proxy is not

[jougs]

@uahic: Can you please provide the exact error messages? Just from your verbal description it does not become clear what the problem is. I.e. what are the SLI commands you're running and what's the error message you receive? From the code it looks as if everything should work. And if it does from Python, this hints at a problem with your SLI code.

[uahic]

Using the SLI interpreter the output is as follows:

SLI ] /music_cont_out_proxy Create /bla Set
Sep 16 13:57:41 Create_l_i [Error]: UnknownModelName
/music_cont_out_proxy is not a known model
name. Please check the modeldict for a list
of available models.

I will recompile NEST, possibly the currently installed version does not include the proxy

[jougs]

I just compiled your branch and calling /music_cont_out_proxy Create works just fine. So your analysis is probably correct.

[jougs]

Please note that Create in SLI does not return the range of IDs as it does in PyNEST, but just the ID of the last created node. This might lead to unexpected results if you create multiple nodes in a single call.

[uahic]

@jougs Thanks for the hint! And yep, after re-compiling it works. Next week there should be some time to spare for creating the SLI test's/examples.

[uahic]

I've wrote half of the unit-test and hopefully will be able to deliver until the end of the week, currently I am pretty busy with project work and want to excuse that I did not have enough time to review Jochen's pull requests
