[jira] [Commented] (SLING-2810) Provide JaCoCo agent servlet to expose code coverage data to HTTP clients during Sling Junit Test execution

["Bertrand Delacretaz (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-2810?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13623677#comment-13623677 ] 

Bertrand Delacretaz commented on SLING-2810:
--------------------------------------------

Thanks very much for your contribution!

Patch applied in 1464991, and I have modified the servlet in revision 1464994 so that /system/sling/jacoco provides information about how to use it, and /system/sling/jacoco/exec provides the binary data. This makes the servlet self-contained, you just need to install it and look at /system/sling/jacoco for instructions.

Please cross-check, including the /system/sling/jacoco usage info, and close this issue if ok.

> create a simple REST endpoint for the jacoco agent at /system/sling/jacoco.exec to expose:
> jacoco Agent Status
> -------------------------------------------------------------------------------------------
> HEAD /system/sling/jacoco.exec
> Content-Type: application/octet-stream
> 200: jacoco agent is attached and exposed through JMX
> 404: jacoco agent not found
> return IAgent.getExecutionData(false)
> -------------------------------------------------------------------------------------------
> GET /system/sling/jacoco.exec
> Content-Type: application/octet-stream
> 200: execution data returned as response entity
> 404: jacoco agent not found
> Reset execution data and return jacoco.exec file
> ----------------------------------------------------------------------
> POST /system/sling/jacoco.exec [optional param ":sessionId" to set a specific sessionId after reset]
> Content-Type: application/octet-stream
> 200: agent was reset (with new sessionId if specified) and prior execution data returned as response entity 
> 404: jacoco agent not found
> Jacoco instrumentation for OSGi is rather limited in the sense that there is one agent per JVM, and resetting the execution data resets it across the board, which means that concurrent requests to this service on a shared integration test server will need to be restricted during test execution to avoid corrupting coverage data.
