[RFC][PATCH v4 0/6] perf config: Reimplement perf_config() using perf_config_set__inter()

Everytime perf_config() is called, perf_config() always read config files. (i.e. user config '~/.perfconfig' and system config '$(sysconfdir)/perfconfig') But we need to use 'struct perf_config_set config_set' variable that already contains all config key-value pairs to avoid this repetitive work

[PATCH v4 2/6] perf config: Add global variable 'config_set'

The config set is prepared by collecting all configs from config files (i.e. user config ~/.perfconfig and system config $(sysconfdir)/perfconfig) so the config set contains all config key-value pairs. We need to use it as global variable to share it. And in near future, the variable will be handl

[PATCH v4 1/6] perf config: Use new perf_config_set__init() to initialize config set

Instead of perf_config(), This function initialize config set collecting all configs from config files (i.e. user config ~/.perfconfig and system config $(sysconfdir)/perfconfig). If there are the same config variable both user and system config file, user config has higher priority than system co

[PATCH v4 5/6] perf config: Reset the config set at only 'config' sub-command

When first calling perf_config(), the config set is initialized collecting both user and system config files (i.e. user config ~/.perfconfig and system config $(sysconfdir)/perfconfig) so config set contains not only user config but also system config key-value pairs. (User config has higher priori

[PATCH v4 6/6] perf config: Reimplement show_config() using perf_config()

Old show_config() directly use config set so there are many duplicated code with perf_config_set__iter(). So reimplement show_config() using perf_config() that use perf_config_set__iter() with config set that already contains all configs. Cc: Namhyung Kim Cc: Jiri Olsa Cc: Masami Hiramatsu Cc:

[PATCH v4 3/6] perf config: Use zfree() instead of free() at perf_config_set__delete()

perf_config_set__delete() delete allocated the config set but the global variable 'config_set' is used all around. So purge and zfree by an address of the global variable , i.e. 'struct perf_config_set **' type instead of using local variable 'set' of which type is 'struct perf_config_set *'. Cc:
