500 internal error loading firefox profile data

https://perf.rust-lang.org/perf/processed-self-profile?commit=36f1f04f18b89ba4a999bcfd6584663fd6fc1c5d&benchmark=keccak-opt&run_name=full&type=crox/marker-chart/?v=5 is a 500. I got there from the detailed self-profile view -> 'Firefox profiler'

Yeah, the self-profile summary views currently don't work; we need to migrate to the new profile format in the frontend. You can download the raw file though and that should work.

I'm confused - the summary view works fine:

It's just the 'processed-self-profile' page that doesn't work.

Thanks, that gave me an .mm_profdata file, but it doesn't track memory usage (rust-lang/rust#81348). Is there a way to see detailed memory usage other than with the 'max-rss' view? That only shows the total change, not what parts of the compiler changed.

[Mark-Simulacrum]

right, yes, I meant the processed ones.

To my knowledge we don't track memory usage on any fine-grained level (I guess other than time-passes, but that has it's own problems) in the compiler today, including on a per-query level in self-profile.

Fixed by #978. Technically doesn't support the old self-profile format, but that's probably not going to be an issue very often. If it becomes one, we can reopen.

Works great, thank you!
