[RFC][PATCH v3 0/4] perf config: Infrastructure code for perf-config

From: Taeung Song
Date: Wed Mar 23 2016 - 16:16:43 EST


We can use the config files (i.e user wide ~/.perfconfig
and system wide $(sysconfdir)/perfconfig)
to configure perf tools. perf-config help user
manage the config files, not manually look into or edit them.

Introduce new infrastructure code for config
management features of perf-config subcommand.

This pathset contains basic code for various purposes of configuration management
showing current configs, in the near future,
showing all configs with default value,
getting current configs from the config files
or writing configs that user type on the config files, etc.

IMHO, I think this infrastructure code is needed
to add new funcationalities for config management of perf-config.

If anyone reviews this, I'd appreciate it.


- use the section list that contains configs each section
instead of the single config list (Namhyung)
- exclude a patch for '--list-all' option from this patchset

- remove perf_config_kind (user, system or both config files)
and needless at this time, etc. (Namhyung)
- separate this patch as several patches (Namhyung)
- fix typing errors, etc.

Taeung Song (4):
perf config: Introduce perf_config_set class
perf config: Let show_config() work with perf_config_set
perf config: Prepare all default configs
perf config: Initialize perf_config_set with all default configs
