The perf-completion.sh uses a predefined string '--help --version
--exec-path --html-path --paginate --no-pager --perf-dir --work-tree
--debugfs-dir' for the bash completion of 'perf --*', which has two
problems:
Problem 1: If the options of perf are changed (see handle_options() in
perf.c), the perf-completion.sh has to be changed at the same time. If
not, the bash completion of 'perf --*' and the options which perf
really supports will be inconsistent.
Problem 2: When typing another single character after 'perf --', e.g.
'h', and hit TAB key to get the bash completion of 'perf --h', the
character 'h' disappears at once. This is not what we want, we wish the
bash completion can return '--help --html-path' and then we can
continue to choose one.
To solve this problem, we add '--list-opts' to perf, which now supports
'perf --list-opts' directly, and its result can be used in bash
completion now.
Example:
Before this patch:
$ perf --h <-- hit TAB key after character 'h'
$ perf -- <-- 'h' disappears and no required result
After this patch:
$ perf --h <-- hit TAB key after character 'h'
--help --html-path <-- the required result
