/*
About variables:
1) Variables represent data fields within a DSP object.
2) Variables may also act as input (kInDsvFl) and/or output (kOutDsvFl) ports.
A. Audio Ports
- Audio output ports (kAudioBufDsvFl) publish a buffer of samples to subscribing
audio input ports on other instances. (See cmDspSysConnectAudio(). )
- Output audio ports are instantiated with physical buffers to hold samples of
audio. Input audio ports contain internal pointers with point to the
audio buffers of connected output ports.
- Set cmDspVarArg_t.cn to the number of channels of audio the buffer will contain.
B. Non-Audio Ports
- Non-audio input ports may register to be called when output port values change.
via cmDspSysInstallCb().
- Type checking is done to guarantee that the output port data type matches one of the
input port types or can be converted to one of the input port types.
[TODO: Check how this is handled in cmDspSetEvent(). Let's say that an input port
takes either a number or string. This conversion is not possible within the
cmDspValue() framework - and yet it should work - or give an error ]
3) Creating variable instances.
A. All variables must be given default values in the instance constructor
_cmDspXXXAlloc(). This can be done automatically be giving default values
in the var args section of the cmDspSysAllocInst() call or by explicitely
setting default values via cmDspSetDefaultXXX() in _cmDspXXXAlloc().
B. The _cmDspXXXReset() function automatically resets all the instance variables to their
default value. By default, variables do not transmit their values when they are
reset to their default value - unless the variable is marked with the kSendDfltDsvFl.
(See cmDspClass.c:cmDspApplyDefault()). The 'out' port on cmDspScalar_t and cmDspButton_t
are examples of instances that transmit their default value on reset.
The order that instances are reset is determined by the order that they were created.
A subtle case can arise when relying on default values to set the initial value of
another object. Given two object instances A and B. Where The output of A has the
the kSendDfltDsvFl set and is connected to an input port on B. If instance A was
created before instance B then instance A will reset before instance B. During reset
the output port of A will transmit it's default value to B - as expected. However
when reset is called on instance B it will overwrite this value with it's own
default value.
In order for this scenario to work - that is the output of instance A sets the initial
value of instance B - instance B must be created first.
Since creation order also determines execution order this solution may not always
be possible. It may be that we would simultaneously like instance A to exeute first
and also recieve its initial value from instance B. Given the above example however
these two goals are mutually exclusive.
[*] This could be solved by explicitely allowing a variable to be reset via
a callback. In this case if a variable was set via a callback during reset
then it would not overwrite that value with its own internal value. This
functionality would need to be set on a per instance bases - which might
not work well with the current cmDspSysAllocInst() var args scheme.
When a single output port is connected to multiple input ports the input ports
are called in the order that the connections were made.
To overcome this problem the reset cycle has been broken into two parts.
In the first part the resetFunc is called on each instance in creation order.
(as described above). Following this pass a second pass is made where the
sysRecvFunc on any instance tagged with the '_reset' attribute is called.
This allows an event callback chain to be executed prior to the first
set of execFunc calls. Note that the event callback chain(s) are programmed
by cmDspInstallCb() connections which are setup on a per application basis.
This allows the initial state of the network to be set outside of the
creation order.
The 'button' instance implements a sysRecvFunc which will send the buttons
value and symbol when called with the '_reset' attribute symbol. If a
'reset' button is created and assigned the '_reset' attribute symbol
(via cmDspSysAssignAttrSymbol()) then the output of the button can be used
to drive a networks initial state in an order determined by the application
programmer.
[TODO: Add a check that all instance variables have default values at the end of
the network reset. This should be easy because the instance variable flag
kDfltSetDsvFl is set in cmDspValueSet() when the default value is set.]
C. The default value of variables may be set via the var args portion of cmDspSysAllocInst().
There is currently a weakness during variable instance creation function
cmDspInstAlloc() uses the cmDspVarArg_t.flags to determine the type of the var arg
argument. cmDspVarArg_t.flags can therefore only be set to one DSV type - and the
actual argument in the cmDspSysAllocInst() call must match that type. This is very
easy to mess up - for example by setting the flag to kIntDsvFl and then putting
0.0 as the var arg value. This limitation also prevents ports which are also
required arguments to cmDspSysAllocInst() (i.e. kReqArgDsvFl) from supporting
multiple types.
There are two possible ways to fix this:
1) Include the type flag in the var args list.
2) Specify a seperate var args flag in cmDspVarArg_t.
Option 1 seems better because:
a. [**] It would allow setting other per instance flags in the cmDspSysAllocInst() call [*].
b. It would support setting a var arg termination flag rather than relying on the current
explicit argument count.
c. This is also the method used in cmJsonMemberValues() and it has worked well there.
Either of these options requires a substantial change to existing code.
This change should therefore be made sooner rather than later.
As the system currently works it is possible, and it often happens, that
an instance's recv function will be called before it is reset. It seems like
this is a bad thing. Maybe the process of resetting and transmitting dflt
values should be broken into seperate passes. This idea could be extended
to type checking as follows:
a. a reset-0 pass is made to set the internal state of each instance to
known values.
b. a type check pass is made where each output port
sends a type msg to all connected input ports to provide the types that
it will send.
c. a reset-1 pass is made allowing all of the type information to be
used to determine the initial state.
d. an initial default value transmission pass is made where some instances
(like scalars) may transmit initial values
e. a reset-2 pass is made allowing the initial values to be acted on.
f. runtime occurs
D. Questions:
0) What are the ways that an instance variable can get set?
a. cmDspValueSet() - This is the canonical value setting function.
All other value setting function call this function.
The cmDspSetXXX() are type safe wrappers to this function.
b. cmDspApplyDefault() - assign the default value to the actual variable
via a call to cmDspValueSet(). This function is automatically called
by cmDspApplyAllDefaults() which is usually in the instance reset function.
c. cmDspSetEvent() - assign the value embedded in an event message
to a variable. This is a wrapper function for cmDspValueSet() which
checks to see if the value need to be echoed to the UI. See
more about UI echoing in the next section.
1) Where do events arriving at an instance receive function originate from?
There are two sources of events:
1. The output ports of other instances.
2. The UI (client application).
Events arriving from the UI can be distinguished from events arriving
from other instances because they have the evt.kUiDspFl flag set.
2) How does UI updating and echoing actually work?
a. Overview:
On creation (in cmDsUi.c) variables whose value must be reflected to the UI
are marked with the kUiDsvFl - these variables are called 'UI variables'.
When a UI variable receive a new value
the new value must be reflected in the associated UI GUI control.
When and how this is accomplished depends on the source of the new
variable value. There are two sources of events arriving at
an instance's receive function: the output port of another instance
or the UI.
Events which originate from the UI are marked with a evt.kUiDspFl.
(cmDspSys.c:_cmDspSysHandleUiMsg())
When a UI variable receives a value from the output port of another
instance (i.e. kUiDspFl not set) then it must always send that value to
the UI. In other words if the evt.kUiDspFl is NOT set then the
value must be sent to the UI.
When a UI variable receives a value from the UI (i.e. the evt.kUiDspFl is set)
it may or may not need to reflect the value. If the UI already
reflects the value then the value does not need to be sent back
otherwise it does.
The UI control determines whether it wants to receive the value it
is sending back by setting the kDuplexDuiFl flag in it's msg to the engine.
Upon receipt of this msg, in cmDspSys.c:_cmDspSysHandleUiMsg(),
the system converts the msg to an event. If the kDuplexDuiFl
is set then the kUiEchoDspFl is set in the event.
When a UI variable receives a value from the UI and the evt.kUiEchoDspFl
is set then the value must be reflected, otherwise it must not.
The rules for updating UI variables (var. w/ kUiDsvFl set) can
be summarized as follows:
kUiDspFl kUiEchoDspFl Send to UI Notes
-------- ------------ ---------- -------------------------------------------------------------
0 0 Yes The value originated from another port and therefore must be reflected.
0 1 <invalid> If kUiEchoDspFl is set then so must kUiDspFl.
1 0 No
1 1 Yes The value originated from the UI and ehco was requested.
This logic is automatically handled together by
cmDspSetEvent() and cmDspValueSet().
b. Variable values are sent and received to and from the UI using
kValueDuiId messages.
c. It is possible to prevent values generated in the engine from being
reflected to the UI by setting the kNoUpdateUiDspFl in the call to
cmDspValueSet().
d. Instance variables are marked as UI variables by the cmDspUIXXXCreate()
functions. Note that instances that have assoicated UI controls generally
have multiple UI variables. (e.g. min,max,step,label,value).
e. Messages arriving from the UI are handled by cmDspSys.c:_cmDspSysHandleUiMsg()
where they are converted to cmDspEvt_t's. All events generated from
msgs arriving from the UI are marked with the kUiDspFl. If the msg kDuplexDuiFl
is set then the event flag kUiEchoDspFl is set - to indicate that the instance
should send the value back to the UI.
This leads to the following potential situation: The msg with kUiEchoDspFl
set arrives at its target instance - which in turn calls cmDspSetEvent() to update
the target variable value. Because kUiEchoDspFl is set the value is automatically
reflected to the UI as expected. However as part of the call to
cmDspValueSet() within cmDspSetEvent() the event is also sent to any connected
instances - a problem would occur if kUiEchoDspFl remained set when it
was sent to the connected instances - because they might then also try to update
their own UI inappropriately. In fact this is not a problem because
_cmDspSendEvt() zeros the the evt.flags value prior to resending the event.
3) Proposed Data Typing Framework:
a. Instance variables are assigned 3 data types:
1. cmDspSysAllocInst() var args type. This is the type that the var args argument
to the instance constructor must be. The value provided by this method
becomes the default value for the variable. This type must be unique - multiple
type flags cannot be used for this value.
2. Strict data type. This is the type used to define the variable value.
Any values which will be used to set the value of this variable must be able
to be converted to this type.
If the variable is used as on input then the system will warn if an output port
is assigned which cannot be converted to this type. If the variable is used as
an output then this is the type the variable will publish as the output type.
All values arriving at the functions 'recv' function are guaranteed to be
able to be converted to this type.
3. Alternate data types. Multiple types may be given to this type.
If no strict data type is given then this will be the set of types accepted
for input and reported for output.
All value messages for the instance which do not fit the strict data type,
but do fit the alternate data type, will be sent to the 'altRecvFunc'
function. The data type of events arriving at this function may therefore
need to be decoded in order to use the assoicated values.
b. Connections from an output with a strict data type can be type checked in
advance - since they are guaranteed to emit a specific data type.
Connections from outputs without strict data types can only be type checked
at runtime - since it is possible for the type to change once the execution
starts.
c. Other notes about data types:
It seems like cmDsvValues() should in general only allow one type flag (along with
the kMtxDsvFl) to be set at a time if the flag state is legal. Is this always the
case? Can a macro be included to routinely check this? Are we careful to
not confuse the actual and possible type flags in DSP instance variables?
This is important when checking the types of variables arriving at in input port.
Include a macro to test the legality of the actual value type leaving output ports
and entering input ports.
Note that the cmXXXDsvFl flags have the problem that it is not possible to
specify some multiple types. For example it is not possible to specify both
scalar and matrix types simultaneously. Once the matrix flag is set it must
be assumed that all specific data types then are matrices.
THIS IS A FUNDAMENTAL PROBLEM THAT MUST BE ADDRESSED.
Note that scalar numeric values can easily be cheaply converted to other numeric
types. It could be expensive however if vectors required conversion.
Vectors are currently being passed as pointers. No conversion is occurring.
d. Another proposal:
Following connection time there is a type determination pass. The network
is traversed in execution order. Each instance computes and emits the single
type assigned to each of its output ports. Once emited these types will not
change during runtime.
Note that this does not preclude an input receiving multiple types.
If a variable arrives at an input port which does not match the type of
the variable associated with that type then it is sent to the NoTypeRecv()
instance function.
2. Do values only get sent on change? If not - why not?
No - based on cmDspClass.ccmDspValueSet() values are transmitted
whenever they are set - there is not check for a change of value.
3. Write a function to support generating multiple enumerated
ports - as is required by AMix or ASplit.
(This is now done: See cmDspClass.h:cmDspArgSetup() )
Update the existing code to use this scheme. (This still needs to be done.)
Similar functions need to be written for connecting groups of ports
in cmDspPgm.c. (This still needs to be done.)
5. It does not appear that the kInDsvFl and kOutDsvFl are actually used during
the connection process. This means that a variable marked as an output
could be used as an input and v.v.. Likewise variable marked as neither input
nor output could be accessed. What are the input and output flags actually
used for?
In fact kInDsvFl and kOutDsvFl are not used at all. (3/18/12).
It might be nice to allow everything to be an output - but to
force inputs to be explicitely named.
6. Is there any implication for marking a variable as both an input and an output?
7. The audio buffers allocated in cmDspInstAlloc() may not be memory aligned.
8. Is there a way to add a generic enable/disable function to all instances?
9. Should all output audio buffers be zeroed by default during _cmDspXXXReset()?
10. Is the kConstDsvFl used? respected? necessary?
yes - it is necessary because some variables cannot be changed after the constructor
is completed. For example any instance that take an argument giving the
number of ports as a variable. The port count argument cannot change because it
might invalidate connections which had been already made to the existing ports.
TODO: find all variables which cannot be changed after the constructor and mark
them as const and prevent them from being the target of connections or events.
11. Is it OK to not assign a variable as either an input or an output. (this would
allow it to be set from cmDspSysAllocInst() but then only changed internally).
12. Write some template DSP instances that provide commented examples of the
common scenarios which an actual instance might encounter.
13. All errors in instances should use cmDspClassErr() or cmDspInstErr() not cmErrMsg().
Update existing code.
14. The way that the master controls are created is wrong. The master controls should
be created during the cmDspSysLoad() process rather than being created in kcApp.cpp.
This would make them essentially identical to other controls - and would allow the
master controls to be manipulated easily from inside a DSP instance.
15. The code for creating and decoding messages seems to be distributed everywhere.
All of this functionality should be moved to cmMsgProtocol.c. See the code
for encoding/decoding messages in cmAudioSys.c as an example.
16. The default behavior of buttons should be to to NOT send out their default values or
symbols on instance reset. Determining whether an output value is sent on instance
reset (as they all are currently ??? or are only UI sent out on reset???)
could be another argument flag setting [**].
17. cmDspInstAlloc() should include another version called cmDspInstAllocV()
which takes the cmDspArg_t fields as var args. This would allow
array variables which currently use cmDspArgSetupN() to be given
in one call - which would be less error prone than using cmDspArgSetupN().
18. Add helper functions to create common dsp instances like:
scalar,button,check,file,audio in,audio out. These functions should
support default values through literals or through resource paths.
19. Design a sub-net function for making sub-nets of instance nets
that can then be treated like instances themselves.
For example make a network of audio sources:
audio file, signal generator, audio input, with gain and frequency
controls.
20. Network construction (cmDspPgm.c) is divided into two parts.
First the instances are allocated and then they are connected.
There should always be a test for a failure between construction
phase and the connection phase and then again after the connection phase.
21. The existing instances are not using cmReal_t and cmSample_t as they should.
22. It is possible for cmDspInstAlloc() to fail in an instance constructor and
yet we are not testing for it in many instances.
When a failure occurs after cmDspInstAlloc() how is the instance deleted
prior to returning? ... is it necessary to delete it prior to returning?
23. For instances which act as files and which take a file name as at an input
port - the correct way to implement the object is to open/reopen the file
both on reset and when a new file name is received.
The reset open covers the case where the default filename is used.
The receieve open covers the case where a filename is received via the input port.
24. After each call to an instance member function (reset,recv,exec,etc.) the
interal error object should be checked. This way an invalid state can
be signaled inside one of the functions without having to worry about
propagating the error to the return value. THis means that as long as
a member function can report and safely complete it doesn't have to do
much error handling internally.
25. As it is currently implemented all audio system sub-system share a
single UDP network managers. This is NOT thread-safe. If more than
one audio sub-system is actually used the program will crash.
This can be solved by giving each sub-system it's own UDP network
manager, where each sub-system is given it's own port number.
