Subject: [PATCH v8 2/4] perf config: Let show_config() work with perf_config_set
Date: Thu, 14 Apr 2016 16:53:19 +0900 [thread overview]
Message-ID: <1460620401-23430-3-git-send-email-treeze.taeung@gmail.com> (raw)
In-Reply-To: <1460620401-23430-1-git-send-email-treeze.taeung@gmail.com>
Current show_config() has a problem when user or
system config files have same config variables i.e.
# cat ~/.perfconfig
[top]
children = false
when $(sysconfdir) is /usr/local/etc
# cat /usr/local/etc/perfconfig
[top]
children = true
Before:
# perf config --user --list
top.children=false
# perf config --system --list
top.children=true
# perf config --list
top.children=true
top.children=false
Because perf_config() can call show_config()
each the config file (user and system).
So fix it.
After:
# perf config --user --list
top.children=false
# perf config --system --list
top.children=true
# perf config --list
top.children=false
