Bug ID: 475982
Summary: pass signals to debugee
Classification: Applications
Product: Heaptrack
Version: 1.5.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: m...@milianw.de
Reporter: hamish+...@risingsoftware.com
Target Milestone: ---
tl;dr: could heaptrack pass signals along to the debugee?
SUMMARY
I'm trying to debug a program which runs in a container. This program normally
runs as the entrypoint of the container, but now I run it inside heaptrack. To
stop the container, the runtime sends SIGINT or SIGTERM to the primary process,
which would cleanly shut down my program but does not get passed through the
heaptrack shell script.
Eventually the container runtime kills all the processes. As a result it looks
like all the memory got leaked because the program did not go through a clean
shutdown.
The same would apply if running heaptrack from a systemd unit.
STEPS TO REPRODUCE
1. Run `heaptrack /usr/bin/sleep 60`
2. Send SIGINT or SIGTERM to heaptrack
OBSERVED RESULT
heaptrack exits on SIGTERM but sleep is still running
SIGINT seems to be ignored completely
EXPECTED RESULT
SIGTERM is sent to debugee
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian bookworm + heaptrack 1.4.0 from package, or heaptrack
1.5.0 compiled from source
