davsclaus opened a new pull request, #28181:
URL: https://github.com/apache/camel/pull/28181
Stacked on #28178 (it needs the `BodyTypeRegistry`). Review that one first;
this PR's own change is the last commit. It is independent of #28180.
This lets the body types a workload brought to each step be read and kept.
For example, run the messages of the expected production workload in a test,
then see what each EIP has been reached with. There are three ways to read
them, besides the Java API (the `BodyTypeRegistry` context plugin):
- **JMX:**
- each processor has `BodyTypes` and `BodyKinds` (`String[]`, kinds as
`null`, `payload`, `data` or `iterator`);
- each route counts its steps reached with more than one type
(`VariedBodyTypes`) and with bodies of more than one kind (`MixedBodyKinds`),
which need attention.
The route console now reads its `variedBodyTypes`/`mixedBodyKinds` from
these attributes, instead of counting them itself.
- **The route coverage dump** (`dumpRoutesCoverageAsXml`, which the Camel
test kits write when route coverage is enabled) has `bodyTypes` and `bodyKinds`
attributes on each step a message reached:
```xml
<to id="result" uri="mock:result" exchangesTotal="2"
totalProcessingTime="0" index="4"
bodyTypes="java.lang.String,java.util.LinkedHashMap"
bodyKinds="payload,data"/>
```
- **A new `body-type` dev console** lists the steps a message has reached,
per route, with their types and kinds. `varied=true` keeps only the steps
reached with more than one type, and `filter` selects routes. The text form
uses the same column as `camel cmd route-structure`.
The Message History docs get a "Dumping the body types" section, and the
catalog gets the new console.
## Tests
- New `ManagedBodyTypesTest` (camel-management): the JMX attributes, the
counts, nothing before a message, and the coverage dump.
- New `BodyTypeDevConsoleTest` (camel-console): steps and kinds, `varied`,
`filter`, nothing reached yet.
- The whole camel-management suite (573) and the whole camel-console suite
(258) pass locally, run against the changed core modules through a scratch
local repository.
