where are the UserTags coming from?

[Seth Ladd]

Hi,

I'm using Observatory to profile my app. I searched across all my code and I couldn't find a use of UserTag. However, I'm seeing this profile:

​

My guess is that some library I'm importing, somehow, has tags.

Is there a way to ignore the tags of libraries that are package: imports? These tags don't mean anything to me.

Thanks!

I don't believe that there is a way to disable user tags from imported libraries, but that seems like a reasonable thing to want to do.  You could file an issue about that and assign it to John.

If you want to verify that UserTags are being created I suppose you could use the allocation profiler to pinpoint where that's happening.
