Follow the same general pattern used in OCD value comparison I think. i.e. provide a single TransitionOperator that provides logical operations over an array namespace. This can start out with a small set of operations and grow as there are quite a few variants that we might want to support inside of a single TransitionOperator vs forcing developers to chain together multiple discrete array operations (less efficient). But, we'll see. Baseline is pretty easy and we'll start there.

If in an ocd namespace you have a map declared:

myMap: { ____types: "jsObject", ____asMap: true, ____defaultValue: {} key: {____accept: "jsObject"} }

If you attempt to write to a key in the map that doesn't exist such as:
( "key1" is not in the map)

ocd.writeNamespace("~...myMap.key1", {foo: "bar"})

Then the writeNamespace filter will throw an exception instead of returning an error as it should.

When using cell process process connect: e.g.

holarchy: { CellProcessProxy: { connect: { proxyPath: "#.something" localCellProcess: { apmID: "foobar", } } } }

If the namespace defined by "proxyPath" does not have "____appdsl: apm: " ....", an error should be returned.

However instead of an error being returned and uncaught exception is thrown: "Handled exception during controller action dispatch: Cannot read property 'apm' of undefined"

The root cause of the exception is here:

https://github.com/Encapsule/holistic/blob/v0.0.46-crossroads/PACKAGES/holarchy/lib/intrinsics/CellProcessProxy/lib/cpp-get-status-filter.js#L82

Because in the expression the second condition throws and error because proxyMemorySpec.____appdsl will be undefined.

This is a feature request to add cardinality transition operator along with the other logical operators in Holarchy core logic.

The cardinality operator will return true/false based on the cardinality of a passed set of other transition operators being true or false. So the request signature might be something like:

cardinality: { ____types: "jsObject", isTrue: { ____types: "jsArray", operandOperatorVariant: { ____accept: "jsObject" } }, equalTo: { ____accept: "jsNumber" } }

Suppose I have a service filter that serves content of type "application/json" as shown below:

let factoryResponse = httpServiceFilterFactory.create({
    id: "TxTaBMnjRAGUkRuf7rwUlg",
    name: "Demo JSON service filter",
    description: "A sample of a service filter that returns JSON as content.",
    constraints: {
         request: {
            content: { encoding: "utf8", type: "text/plain" },
            query_spec: { ____opaque: true },
            request_spec: { ____opaque: true },
            options_spec: { ____opaque: true }
        },
        response: {
            content: { encoding: "utf8", type: "application/json" },
            error_context_spec: { ____opaque: true },
            result_spec: { ____opaque: true }
        }
    },
    handlers: {
        request_handler: (request_) => {
            request_.response_filters.result.request({
                streams: request_.streams,
                integrations: request_.integrations,
                request_descriptor: request_.request_descriptor,
                response_descriptor: {
                    http: { code: 200 },
                    content: { encoding: "utf8", type: "application/json" },
                    data: {foo: "bar"}
                }
            });
            return {result: undefined};
        }
    }
});

if (factoryResponse.error) throw new Error(factoryResponse.error);
const demoJSONServiceFilter = factoryResponse.result;

The value of what will be the "content-type" header in the response is clearly "application/json"

When binding that service filter to a route in the config.services object used when constructing the holism server, I am also required to specify the "contentType"

{
    authentication: { required: false },
    filter: demoAsyncServiceFilter,
    request_bindings: { method: "GET", uris: [ "/demoasync" ] },
    response_properties: { contentEncoding: "utf8", contentType: "application/json" },
}

So I have now specified the "content-type" in 2 places, so which value is actually used?

If I change the "contentType" in the binding to something else e.g. "text/html" then the value I actually see when making the request remains "application/json", so clearly the value in the binding is not being used. If I remove, the contentType from "response_properties" then an exception from a filter error for the missing contentType member is thrown and server start fails.

The conclusion is that the "contentType" in the binding is not actually used for the "content-type" header in the response, yet I am still required to provide it.

When starting a cell process using:

holarchy: { CellProcessor: { process: { create: { apmID: "12345 ..." } } } }

A "cellProcessUniqueName" is not required, the name is defaulted to "singleton" by the cpm.

When I go to query for the same process, I have to pass in "singleton" for "cellProcesssUniqueName" or the query will not find the process. In other words:

holarchy: { CellProcessor: { process: { query: { queryCellProcess: { cellProcessNamespace: { apmID, //TODO this shouldn't be required after upgrading to the latest version of holistic. cellProcessUniqueName: "singleton" } } } } } }

Works whereas:

holarchy: { CellProcessor: { process: { query: { queryCellProcess: { cellProcessNamespace: { apmID, } } } } } }

does not.

If I am not required to pass in a unique name to create the process, I should not be required to pass in the uniqueName to query it. Getting the query to work requires me to know the default name that is being used by the CPM.

ComponentRouter:

https://github.com/Encapsule/holistic/blob/v0.0.46-crossroads/PACKAGES/d2r2/lib/ComponentRouter.jsx#L168

Currently requires specific themes e.g. metadata.site.theme.ComponentRouterError... to be present in the render context to correctly render if an error occurs such as not finding a registered r2d2 component for the render message. In the absence of the correct theme in the render context, the ComponentRouter React component throws and renders nothing.

It is not reasonable for consumers of ComponentRouter to be aware and provide themes specific to ComponentRouter in the renderContext in order for it to properly handle errors.

All modules under HOLISTIC/PACKAGES are using an older version of yarn.

"engines": { "node": ">=12.16.1 <13", "yarn": "1.22.0" },

Update to the LTS of yarn "1.22.4"

Inside the bodyFunction of a controller action, one may want to read from a sub namespace that is connected by a proxy. Using context.ocdi.readNamespace in a proxied namespace will yield a result like:

{
    CPPU-UPgS8eWiMap3Ixovg_private: {

        lcpConnect: "~.gFUcyA0qSrq7Z4Vpn1oIZA_CellProcesses.cellProcessMap.4ODg4BoaGhqkpKSkX19fXw"

        lcpRequest: {

            apmID: "gFUcyA0qSrq7Z4Vpn1oIZA",

            instanceName: "singleton"
   }
}

If I want to read from the actual proxied apm ocd, I can do something like this, to the the lcpConnect string and then use that as a path value to read the actual value from the proxy:

const lcpConnect = readResponse.result[Object.keys(readResponse.result)[0]].lcpConnect;
readResponse = context.ocdi.readNamespace(lcpConnect);

This is a very clunky implementation, either readNamespace needs to be able to sort out a proxied namespace, or we need some sort of wrapper function to do the same.

From the perspective of this error handler it's difficult to say precisely what this error means given the broad semantics of ControllerAction plug-in filters. Here is a list of possible problems in decreasing order of liklihood: Your request format may be invalid above the point in the request data where the message router made its delegate selection and this error is the plug-in rejecting the request entirely. Or, the selected ControllerAction plug-in filter may implement some sort of additional input value validation that constrains the permissible input beyond what's examined by the message router and ControllerAction plug-in filters. And, you've violated API constraints. Or, you have made a valid request but applied the action to the wrong type of cell (i.e. you think you're acting on a cell bound to APM X but it's really bound to a Y). Or, the cell you're attempting to act upon is not in the correct process step or otherwise prepared to accept or take action on behalf of the caller. Or, there's a bug in the ControllerAction plug-in filter itself. If you track down the source of this error and it's not on this list please report it!" ....

I would normally expect the semantics of a query to be such that not finding the thing that I query would return an empty result not an error.

While building a holism derived Node server via AWS code pipeline, I encountered the following issue.

https://forums.aws.amazon.com/thread.jspa?threadID=251732

The summary of the issue is that the .git directory and hence any git commands are not available on the build server, and this causes the derived generate script: "generate-runtime-build-tag.js" to fail which fails the build. There is an environment variable available that contains the git hash of the commit being built. Therefore, to build a holism derived server on AWS Code Pipeline requires a small modification to the below file:

https://github.com/Encapsule/holistic/blob/master/PROJECT/GENERATOR/TEMPLATES/generate-runtime-buildtag.js.hbs

Which could look like this:

let commitHash;

if (process.env.CODEBUILD_RESOLVED_SOURCE_VERSION) {
    commitHash = process.env.CODEBUILD_RESOLVED_SOURCE_VERSION
} else {
    commitHash = childProcess.execSync('git rev-parse HEAD').toString('utf8').trim();
}

The delegate transition operator with signature:

CellProcessor: { cell: { cellCoordinates: "#.cell2Proxy", delegate: { ...

Does not work, the operator being dispatched does not get the correct apmBindingPath.

An example is in this branch: https://github.com/Viewpath/viewpath5/tree/delegate-bug

node
var cp = require("./SOURCES/CLIENT/delegate-test")

cp.toJSON().opc.toJSON().ocdi.toJSON().PKj0xsAzRkC9SR_TiS1ZrA_CellProcesses

{ cellProcessMap: { '4ODg4BoaGhqkpKSkX19fXw': { cell2Proxy: [Object], __apmiStep: 'waiting_for_cell_2' } }, revision: 1 }

The APM for cell1 " '4ODg4BoaGhqkpKSkX19fXw" should transition to ready state because cell2 " x7pM9bwcReupSRh0fcYTgw" is in ready state but no such transition occurs.

https://github.com/Viewpath/viewpath5/blob/delegate-bug/SOURCES/CLIENT/delegate-test/cellModel1/index.js#L54

Looking at the debugger it does not appear that the apmBindingPath is being resolved correctly in the proxy in the implementation for the delegate operator.

When an action signature is in an APM as an "enter" or "exit" action, it would be great to have some context from the transition included when that action is dispatched from opc.evaluate(). Currently, inside an action bodyFunction there is no way to tell what the target state of the APM is for the invocation. Actions currently have access to the "__apmiStep" from the ocdi, but that will contain the step that was last written to the ocdi and not the step that the APM will be (potentially) transitioning to.

Similarly it would be nice to know within a bodyFunction of an action whether the action was invoked by an external actor as opposed to opc.evaluate(), because most actions will be intended for one manner of invocation or the other, but not both and there is currently no way to distinguish them at runtime.
