tools lib subcmd: Make it an error to pass a signed value to OPTION_UINTEGER

2017-02-14T18:19:17Z

Options marked OPTION_UINTEGER or OPTION_U64 clearly indicates that an unsigned value is expected, so just error out when a negative value is passed, instead of returning something undesired to the tool. E.g.: # perf bench futex hash -t -4 # Running 'futex/hash' benchmark: Error: switch `t' expects an unsigned numerical value Usage: perf bench futex hash -t, --threads Specify amount of threads # Cc: Adrian Hunter Cc: David Ahern Cc: Davidlohr Bueso Cc: Jiri Olsa Cc: Josh Poimboeuf Cc: Namhyung Kim Cc: Wang Nan Link: http://lkml.kernel.org/n/tip-2mdn8s2raatyhz7tamrsz22r@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

tools lib subcmd: Suppport cascading options

2016-10-25T13:12:16Z

Sometimes subcommand have common options and it can only handled in the upper level command unless it duplicates the options. This patch adds a parent field and fallback to the parent if the given argument was not found in the current options.

perf subcmd: Create subcmd library

2015-12-17T17:27:14Z

Move the subcommand-related files from perf to a new library named libsubcmd.a. Since we're moving files anyway, go ahead and rename 'exec_cmd.*' to 'exec-cmd.*' to be consistent with the naming of all the other files.
