How can the source view be enabled?

[sbueringer]

Hey folks,

I noticed that a while ago the source view was disabled by default (#3668).

As it is only disabled per default, how can the source view be enabled?

[brancz]

We disabled it by default because the symbolizer in Parca is not very good at getting line numbers right, so we felt that enabling it would cause more harm than good since Parca is unlikely to display the correct thing in the first place.

It's been on our list to fix this for a loooooong time, but we haven't gotten around to it yet.

[sbueringer]

Thx, that's very useful context.

I hacked around it for now by manually hard-coding enableSourcesView to true and as far as I can tell for Go profiles collected from a pprof endpoint everything works flawlessly (at least in my case)

[brancz]

Yeah, pre-symbolized data from a pprof endpoint is gonna work fine.

Ok, if you want to send a PR to enable it, I think I'd be ok with it. If someone thinks asynchronously symbolized data looks off then we'd just say that on an issue that someone would open.

[sbueringer]

Perfect, sounds good. I've opened a PR.

I'm not sure if there are other changes needed apart from changing the bool. For me that was enough to be able to use it, but I'm not really familiar with the code base.
