[PATCH v8 1/7] perf config: Introduce default_config_section and default_config_item for default config key-value pairs

2016-09-04 Thread Taeung Song
When initializing default perf config values,
we currently use values of actual type(int, bool, char *, etc.).

For example,
If there isn't a user config value for 'annotate.use_offset'
config variable at ~/.perfconfig,
default value for it is 'true' bool type value in perf like below.

At ui/browsers/annoate.c

static struct annotate_browser_opt {
bool hide_src_code,
 use_offset,
 jump_arrows,
 show_linenr,
 show_nr_jumps,
 show_total_period;
} annotate_browser__opts = {
.use_offset  = true,
.jump_arrows = true,
};

But I suggest using 'struct default_config_section' and
'struct default_config_item' that can contain default config key-value pairs
in order to initialize default config values with them, in near future.

If we do, we could manage default perf config values at one spot (i.e. 
util/config.c)
with default config arrays and it could be easy and simple to modify
existing default config values or add default values for new config item.
