Jakub Kicinski ebe3bdc435 tools: ynl: throw a more meaningful exception if family not supported ... cli.py currently throws a pure KeyError if kernel doesn't support a netlink family. Users who did not write ynl (hah) may waste their time investigating what's wrong with the Python code. Improve the error message: Traceback (most recent call last): File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 362, in __init__ self.family = GenlFamily(self.yaml['name']) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 331, in __init__ self.genl_family = genl_family_name_to_id[family_name] ~~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^ KeyError: 'netdev' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "/home/kicinski/devel/linux/./tools/net/ynl/cli.py", line 52, in <module> main() File "/home/kicinski/devel/linux/./tools/net/ynl/cli.py", line 31, in main ynl = YnlFamily(args.spec, args.schema) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/home/kicinski/devel/linux/tools/net/ynl/lib/ynl.py", line 364, in __init__ raise Exception(f"Family '{self.yaml['name']}' not supported by the kernel") Exception: Family 'netdev' not supported by the kernel Signed-off-by: Jakub Kicinski <kuba@kernel.org> Link: https://lore.kernel.org/r/20230407145609.297525-1-kuba@kernel.org Signed-off-by: Paolo Abeni <pabeni@redhat.com>		2023-04-11 15:33:46 +02:00
