Source: libcamera
Severity: wishlist
libcamera has libunwind integration, which is currently enabled on
architectures where libunwind exists. It seems to be used to print better
backtraces on a fatal signal or assertion failure.
While nice to have, this doesn't seem hugely important: under normal
circumstances, libcamera shouldn't be crashing, and if it crashes due
to a bug, tools like systemd-coredump are a more reliable way to get
high-quality backtraces (without requiring the crashing process to still
be in a mostly-working state).
Meanwhile, libunwind has several unaddressed RC bugs.
The readme also suggests that if we have libdw (and glibc), there's no
benefit to also having libunwind:
> for improved debugging: [optional]
> libdw-dev libunwind-dev
>
> libdw and libunwind provide backtraces to help debugging assertion
> failures. Their functions overlap, libdw provides the most detailed
> information, and libunwind is not needed if both libdw and the glibc
> backtrace() function are available.
So it might be a good idea to reduce the key package status of libunwind
by disabling the libunwind integration on all architectures, and instead
relying on libdw/backtrace() or post-mortem core dump analysis?
Thanks,
Simon
