  "message": "Fix race condition in reload_on_sighup functional\n\nRace condition appears in next situation:\n\n  1. First thread calls _set_config_value for one section.\n  2. Second thread calls _set_config_value for another section.\n  3. First thread. Config option value set, calls\n     open(self.config_file, \u0027wb\u0027), which erases all file content.\n  4. Second thread. In previous point moment second thread tries to\n     set config option value to self.config_file, which is empty (see 3).\n     So, NoSectionError exception raised.\n\nThis patch adds ten retries for setting option value, if NoSectionError\nraised, i.e. try to wait until self.config_file is busy.\n\nChange-Id: Ic54ea287ebe4724511f75d42677cae5dfdec4e57\nCloses-bug: #1535766\n",
