[PATCH] sysctl: Fix refreshing cache

Fix iterating over the 'cache' dictionary in refresh(). A dictionary is not callable. This fixes the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.6/site-packages/procfs/sysctl.py", line 64, in refresh for key in self.cache(): TypeError: 'dict' object is not callable Signed-off-by: Ondřej Lysoněk <olysonek(a)redhat.com&gt; --- procfs/sysctl.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/procfs/sysctl.py b/procfs/sysctl.py index 8b256ab..6a91455 100755 --- a/procfs/sysctl.py +++ b/procfs/sysctl.py @@ -61,7 +61,7 @@ class sysctl: f.close() def refresh(self): - for key in self.cache(): + for key in self.cache.keys(): del self.cache[key] value = self.read(key) if value != None: -- 2.17.2
