Bug ID: 32062
Summary: analyze eu-stacktrace w.r.t. debuginfod
Product: elfutils
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: tools
Assignee: unassigned at sourceware dot org
Reporter: fche at redhat dot com
CC: elfutils-devel at sourceware dot org
Target Milestone: ---
May need debuginfod help in case of:
- lack of buildid-matching executable (for .eh_frame)
- lack of buildid-matching debuginfo (if .eh_frame is absent, so need
.debug_frame)
So for those cases, consider some mixture of:
- diagnostics: enumerate newly encountered buildids for reporting
- invoke debuginfod-find {executable,debuginfo} (which?) $buildid in background
- have eu-stacktrace NOT disable debuginfod fallback hooks
- check how much latency (downloading time) might be tolerable to
sysprof/consumers
- check how much RAM could be consumed by copying incoming stack-dump ring
buffer frames while waiting for debuginfo /etc. download
- check whether $DEBUGINFOD_MAXTIME is sufficient knob of control
