"failed to fetch any source profiles"

Sometimes I click on a blob in the timeline and it opens up a page saying “failed to fetch any source profiles”.

I have seen three different log messages that all seem to be associated with (different variants of?) this issue:

2019/11/28 18:03:48 : decompressing profile: gzip: invalid header
2019/11/28 18:04:46 : decompressing profile: unexpected EOF
2019/11/28 18:07:49 : parsing profile: unrecognized profile format

I guess it’s always possible that the scrape fails, but it would be better if the UI didn’t show a blob at that time.

I finally managed to find that last bug, and all new e2e tests are passing with this patch: https://github.com/conprof/conprof/pull/113

Thank you so much everyone for bearing with me!

Quick update: It appears I have found part of the problem, there was an unsafe loading of data in the WAL. So the good news is that there is no corruption of the data on disk. Bad news is that for some reason new appends still yield this error, but when restarted those appends can be viewed without issues. I’m continuing to investigate.

I’ll open a PR as soon as I fix the remaining issue.
