The server is designed using ``asyncio`` so that it can easily support

simple cases: it allows new connections to be be accepted even when the

If a target method is a coroutine, it is awaited and its return value

is sent to the RPC client. If ``allow_parallel`` is true, multiple

This module provides serialization and deserialization functions for Python
|
||||
objects. Its main features are:
|
||||
|
||||
* Human-readable format compatible with the Python syntax.
|
||||
* Each object is serialized on a single line, with only ASCII characters.
|
||||
* Supports all basic Python data structures: None, booleans, integers,
|
||||
floats, complex numbers, strings, tuples, lists, dictionaries.
|
||||
* Those data types are accurately reconstructed (unlike JSON where e.g. tuples
|
||||
become lists, and dictionary keys are turned into strings).
|
||||
* Supports Numpy arrays.
|
||||
|
||||
The main rationale for this new custom serializer (instead of using JSON) is
|
||||
that JSON does not support Numpy and more generally cannot be extended with
|
||||
other data types while keeping a concise syntax. Here we can use the Python
|
||||
function call syntax to express special data types.

This module provides facilities for experiment to execute code remotely on

controllers.

The remotely executed code has direct access to the driver, so it can transfer
|
||||
large amounts of data with it, and only exchange higher-level, processed data
|
||||
with the experiment (and over the network).
|
||||
|
||||
Controllers with support for remote execution contain an additional target
|
||||
that gives RPC access to instances of :class:`.RemoteExecServer`. One such instance
|
||||
is created per client (experiment) connection and manages one Python namespace
|
||||
in which the experiment can execute arbitrary code by calling the methods of
|
||||
:class:`.RemoteExecServer`.
|
||||
|
||||
The namespaces are initialized with the following global values:
|
||||
|
||||
* ``controller_driver`` - the driver instance of the controller.
|
||||
* ``controller_initial_namespace`` - a controller-wide dictionary copied
|
||||
when initializing a new namespace.
|
||||
* all values from ``controller_initial_namespace``.
|

Developing a Network Device Support Package (NDSP)
|
||||
==================================================
|
||||
|
||||
Most ARTIQ devices are interfaced through "controllers" that expose RPC interfaces to the network (based on :class:`artiq.protocols.pc_rpc`). The master never does direct I/O to the devices, but issues RPCs to the controllers when needed. As opposed to running everything on the master, this architecture has those main advantages:

Most ARTIQ devices are interfaced through "controllers" that expose RPC interfaces to the network (based on SiPyCo). The master never does direct I/O to the devices, but issues RPCs to the controllers when needed. As opposed to running everything on the master, this architecture has those main advantages:
|
||||
|
||||
* Each driver can be run on a different machine, which alleviates cabling issues and OS compatibility problems.
|
||||
* Reduces the impact of driver crashes.
|
||||
@ -15,13 +15,13 @@ A network device support package (NDSP) is composed of several parts:
|
||||
|
||||
1. The `driver`, which contains the Python API functions to be called over the network, and performs the I/O to the device. The top-level module of the driver is called ``artiq.devices.XXX.driver``.
|
||||
2. The `controller`, which instantiates, initializes and terminates the driver, and sets up the RPC server. The controller is a front-end command-line tool to the user and is called ``artiq.frontend.aqctl_XXX``. A ``setup.py`` entry must also be created to install it.
|
||||
3. An optional `client`, which connects to the controller and exposes the functions of the driver as a command-line interface. Clients are front-end tools (called ``artiq.frontend.aqcli_XXX``) that have ``setup.py`` entries. In most cases, a custom client is not needed and the generic ``artiq_rpctool`` utility can be used instead. Custom clients are only required when large amounts of data must be transferred over the network API, that would be unwieldy to pass as ``artiq_rpctool`` command-line parameters.

Custom clients are only required when large amounts of data must be transferred over the network API, that would be unwieldy to pass as ``sipyco_rpctool`` command-line parameters.
|
||||
4. An optional `mediator`, which is code executed on the client that supplements the network API. A mediator may contain kernels that control real-time signals such as TTL lines connected to the device. Simple devices use the network API directly and do not have a mediator. Mediator modules are called ``artiq.devices.XXX.mediator`` and their public classes are exported at the ``artiq.devices.XXX`` level (via ``__init__.py``) for direct import and use by the experiments.
|
||||
|
||||
The driver and controller
|
||||
-------------------------
|
||||
|

A controller is a piece of software that receives commands from a client over the network (or the ``localhost`` interface), drives a device, and returns information about the device to the client. The mechanism used is remote procedure calls (RPCs) using :class:`artiq.protocols.pc_rpc`, which makes the network layers transparent for the driver's user.

Logging

-------
|

For the debug, information and warning messages, use the ``logging`` Python module and print the log on the standard error output (the default setting). The logging level is by default "WARNING", meaning that only warning messages and more critical messages will get printed (and no debug nor information messages). By calling :func:`artiq.tools.add_common_args` with the parser as argument, you add support for the ``--verbose`` (``-v``) and ``--quiet`` (``-q``) arguments in the parser. Each occurence of ``-v`` (resp. ``-q``) in the arguments will increase (resp. decrease) the log level of the logging module. For instance, if only one ``-v`` is present in the arguments, then more messages (info, warning and above) will get printed. If only one ``-q`` is present in the arguments, then only errors and critical messages will get printed. If ``-qq`` is present in the arguments, then only critical messages will get printed, but no debug/info/warning/error.

* Controllers must be able to operate in "simulation" mode, where they behave properly even if the associated hardware is not connected. For example, they can print the data to the console instead of sending it to the device, or dump it into a file.
|

* The simulation mode is entered whenever the ``--simulation`` option is specified.
|
||||
* Keep command line parameters consistent across clients/controllers. When adding new command line options, look for a client/controller that does a similar thing and follow its use of ``argparse``. If the original client/controller could use ``argparse`` in a better way, improve it.

This tool is the preferred way of handling simple ARTIQ controllers.
|
||||
Instead of writing a client for very simple cases you can just use this tool
|
||||
in order to call remote functions of an ARTIQ controller.
|
||||
|
||||
* Listing existing targets
|
||||
|
||||
The ``list-targets`` sub-command will print to standard output the
|
||||
target list of the remote server::
|
||||
|
||||
$ artiq_rpctool hostname port list-targets
|
||||
|
||||
* Listing callable functions
|
||||
|
||||
The ``list-methods`` sub-command will print to standard output a sorted
|
||||
list of the functions you can call on the remote server's target.
|
||||
|
||||
The list will contain function names, signatures (arguments) and
|
||||
docstrings.
|
||||
|
||||
If the server has only one target, you can do::
|
||||
|
||||
$ artiq_rpctool hostname port list-methods
|
||||
|
||||
Otherwise you need to specify the target, using the ``-t target``
|
||||
option::
|
||||
|
||||
$ artiq_rpctool hostname port list-methods -t target_name
|
||||
|
||||
* Remotely calling a function
|
||||
|
||||
The ``call`` sub-command will call a function on the specified remote
|
||||
server's target, passing the specified arguments.
|
||||
Like with the previous sub-command, you only need to provide the target
|
||||
name (with ``-t target``) if the server hosts several targets.
|
||||
|
||||
The following example will call the ``set_attenuation`` method of the
|
||||
Lda controller with the argument ``5``::
|
||||
|
||||
$ artiq_rpctool ::1 3253 call -t lda set_attenuation 5
|
||||
|
||||
In general, to call a function named ``f`` with N arguments named
|
||||
respectively ``x1, x2, ..., xN`` you can do::
|
||||
|
||||
$ artiq_rpctool hostname port call -t target f x1 x2 ... xN
|
||||
|
||||
You can use Python syntax to compute arguments as they will be passed
|
||||
to the ``eval()`` primitive. The numpy package is available in the namespace
|
||||
as ``np``. Beware to use quotes to separate arguments which use spaces::
|
||||
|
||||
$ artiq_rpctool hostname port call -t target f '3 * 4 + 2' True '[1, 2]'
|
||||
$ artiq_rpctool ::1 3256 call load_sample_values 'np.array([1.0, 2.0], dtype=float)'
|
||||
|
||||
If the called function has a return value, it will get printed to
|
||||
the standard output if the value is not None like in the standard
|
||||
python interactive console::
|
||||
|
||||
$ artiq_rpctool ::1 3253 call get_attenuation
