Structural output - RefreshLastRun

[jan-goral]

According to the description of epic #1728, prepare a specification document for the structural output based on the following requirements:

• Identify all places that are producing console logs and list them in the specification.
• Specify dedicated types and structures for logs with places (packages and namespaces) for them.
• Specify proposition how to pass out function reference to low-level functions that producing logs.

Make sure that specification is sufficient to implement structured output without a doubt.

Command

RefreshLastRun

[piotradamczyk5]

Places which produce output logs

1. Loading run ftl.run.common.GetLastMatrices#L15
logLn("Loading run $lastRun")

2. Start info ftl.run.RefreshLastRun#L44
logLn("RefreshMatrices")

3. Refresh info ftl.run.RefreshLastRun#L58
logLn(FtlConstants.indent + "Refreshing ${matrixCount}x matrices")

4. Matrix info for each matrix ftl.run.RefreshLastRun#L65
logLn(FtlConstants.indent + "${matrix.state} $matrixId")

5. Update matrix file ftl.run.RefreshLastRun#L76
logLn(FtlConstants.indent + "Updating matrix file")

• ReportManager places which will be handled together with #1871 and #1870

Structures for messages

sealed interface RefreshLastRunState {
    data class LoadingRun(val lastRun: String) : RefreshLastRunState
    object RefreshMatricesStarted : RefreshLastRunState
    data class RefreshMatrices(val matrixCount: Int) : RefreshLastRunState
    data class RefreshMatrix(val matrixState: String, val matrixId: String) : RefreshLastRunState
    object UpdatingMatrixFile : RefreshLastRunState
}

• ReportManager state which will be handled together with #1871 and #1870

Proposition of passing out function

Wiill be handled together with #1871 and [#1870](

sealed interface RunState

sealed interface ReportManagerState : RunState {
    data class Log(val message: String) : ReportManagerState
    data class Warning(val message: String) : ReportManagerState
    data class ShardTimes(val shards: List<ReportManager.ShardEfficiency>)
}

data class Uploading(val name: String, val path: String) : RunState

---

Since logs are not produced (and printed) in single action we can introduce a wrapper for a channel that will collect logs

object StateHolder {
    val logs = Channel<RunState>()
}

than we can replace logLn functions with StateHolder.logs.trySend(Warning(...))

The presentation layer will listen to any messages from StateHolder and depending on if it is desktop/cli (or sth else) it will be handled differently.

RefreshLastRunState, RunIosTestState etc. will implement RunState interface. That will allow to reuse logging logic and have only one source of logs (which would be easier to handle)

@jan-gogo could you verify the proposed solution?

[jan-goral]

Looks ok, approved.
