From the hotspot bug tracker:
Is your feature request related to a problem? Please describe.
I'm inspecting issues seen in perfparser and find it hard to go on with the appimage provided version.
One of the reasons is that appimage creation uses centos7 (I guess it is still at "debuginfod only for centos8+9 state) and more important: the elfutils used, which make the biggest part of perfutils (
perf recordshows 98.5% spent in hotspot-perfparser is inPerfRecordSample::PerfRecordSample(PerfRecordSample&&)), is statically linked, so not well visible withlddeither.Describe the solution you'd like
Include elfutils version in an extra line in
hotspot-perfparser- both to make it more clear what is used and to give credits to the library that seems to do most of the actual work.Furthermore it would be very good if the appimage debuginfo download could include the elfutils debuginfo package.
Describe alternatives you've considered
None.
