Verified the case for file path with Permission issue but Clio handled and threw an exception.
2024-04-05 08:35:16.689733 (util/log/Logger.hpp:346) [0x00000001fb4c3ac0] General:FTL Exit on exception: boost::filesystem::create_directories: Permission denied [system:13]: "/var/log/clio/clio.log", "/var/log/clio"

Please verify the above case too before closing the issue.

This is not a crash - the same happens on any other misconfiguration. Clio detects it, logs and exits cleanly.
To me this looks like the correct/expected behaviour. Let us know if you disagree and what would be a good way to handle this. Thanks

[legleux]

If the error is legitimately Permission denied, it probably is the correct behavior.
If you mess with rippled's paths as root (or any non-rippled user) you'll get a similar issue.

The ownership of the directories will depend on which user initially ran clio_server of course.

@legleux yes but there is slightly more to it than i thought originally. We do treat the permission error correctly but then some other exception happens when shutting down the rest of Clio and that is what produces the trace. While the first part is expected, the second part is certainly not! But we also have other issues in the pipeline that meant to battle similar problems (at least #442 is related).
