ScoreDataExtractor crashes when stopping about compilescore

[b-winkler]

Hi Ramon,

thanks for the quick response. Yes, you were right, the extraction is the one causing problems, .etl file is created successfully.
I will try to analyze the extraction issue as you proposed, will get back to you with more infos. But this will probably take a few days.

Cheers,
Benjamin

PS: I could not find information about why ScoreGenerator needs to be started in elevated mode. Did not seem to make a difference in my environment?

Sorry for the delay.
I just ran ScoreDataExtractor in Debug mode and reproduced the crash, only to find out that someone else has reported the same bug, just with more detailed information.
So, same here: OnCompilerPassStart() is being called with activity.InputSourcePath and activity.OutputObjectPath == nullptr

I think I got a workaround for the issue with the missing activity names meanwhile it is not fixed in the SDK.

FYI, I left a more detailed information of the workaround in the other issue thread

Whenever you have time could you validate if the profiler works on version 1.5.6 when using the /MP ( which was the root cause of the SDK not giving up the path names ).

Thanks for the investigation, I really appreciate it.

Hey Ramon,
workaround seems to have fixed it. At least it did not crash anymore, though I did not look into the results, yet. Will do that later.

Sorry about that. Sadly, there is not much information I can use to pinpoint the issue.

In order to narrow it down, I would recommend to do the following steps:

• ScoreDataExtractor.exe -msvc -start
• Build your sources
• ScoreDataExtractor.exe -msvc -stop -o <yourfolder>\output.etl (this will store the event capture in an event trace log format. Which can be later processed)
• ScoreDataExtractor.exe -msvc -extract -i <yourfolder>\output.etl -o <yourfolder>\output.scor (this will process the event trace log into the aggregated scor file)

This way we can see what is the problematic step (gathering or processing)
I am pretty sure it is failing in the extraction/processing part (as the first one is mainly MS Build insights sdk calls for msvc), but always good to double check.

If the extractor is the one crashing I would then recommend to just clone this repo, open the DataExtractorSolution, Go to the Project Settings - Debugging and use the command arguments from the last step. This way we will get a callstack. Also, because the data is already in the etl file VS does not need to run in Admin mode.

Thanks for your help. Please let me know the outcome.

No rush! Let me know what you find in there.

I checked what you are mentioning about the elevated mode and you are right, maybe MS updated their Build insights to not require it anymore and I was still under the impression it was mandatory. I will run some tests and remove the elevated requirement if it is not needed anymore.

Thanks for letting me know!

Edit: After several tests... I will remove the elevated restriction as apparently it is not needed anymore! Good news! :)
