This module provides a remote procedure call (RPC) mechanism over sockets
between conventional computers (PCs) running Python. It strives to be
transparent and uses :mod:`artiq.protocols.pyon` internally so that e.g. Numpy
arrays can be easily used.
Note that the server operates on copies of objects provided by the client,
and modifications to mutable types are not written back. For example, if the
client passes a list as a parameter of an RPC method, and that method
``append()s`` an element to the list, the element is not appended to the
client's list.

For example, if the server provides method ``foo``, and ``c`` is a local

result = c.foo(param1, param2)
The parameters and the result are automatically transferred from the
server.
Only methods are supported. Attributes must be accessed by providing and
using "get" and/or "set" methods on the server side.
At object initialization, the connection to the remote server is
automatically attempted. The user must call :meth:`~artiq.protocols.pc_rpc.Client.close_rpc` to
free resources properly after initialization completes successfully.
:param host: Identifier of the server. The string can represent a
hostname or a IPv4 or IPv6 address (see
``socket.create_connection`` in the Python standard library).
:param port: TCP port to use.
:param target_name: Target name to select. ``IncompatibleServer`` is
raised if the target does not exist.
Use :class:`.AutoTarget` for automatic selection if the server has only one
target.
Use ``None`` to skip selecting a target. The list of targets can then
be retrieved using :meth:`~artiq.protocols.pc_rpc.Client.get_rpc_id`
and then one can be selected later using :meth:`~artiq.protocols.pc_rpc.Client.select_rpc_target`.
:param timeout: Socket operation timeout. Use ``None`` for blocking
(default), ``0`` for non-blocking, and a finite value to raise
``socket.timeout`` if an operation does not complete within the
given time. See also ``socket.create_connection()`` and
``socket.settimeout()`` in the Python standard library. A timeout

The server is designed using ``asyncio`` so that it can easily support
multiple connections without the locking issues that arise in
multi-threaded applications. Multiple connection support is useful even in
simple cases: it allows new connections to be be accepted even when the
previous client failed to properly shut down its connection.
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
target coroutines may be executed in parallel (one per RPC client),
otherwise a lock ensures that the calls from several clients are executed
sequentially.

exposed to the client. Keys are names identifying each object.
Clients select one of these objects using its name upon connection.
:param description: An optional human-readable string giving more

"""
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``.
Access to a controller with support for remote execution is done through an
additional device database entry of this form: ::
"$REXEC_DEVICE_NAME": {

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.

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.
* Use docstrings for all public methods of the driver (note that those will be retrieved by ``artiq_rpctool``).

Remote Procedure Call tool

.. argparse::

:prog: artiq_rpctool
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
5.0 dB
