Branch: refs/heads/master Home: https://github.com/tribe29/checkmk Commit: a33bb33f01573123fdaccfe95bf6dcee99a550e5 https://github.com/tribe29/checkmk/commit/a33bb33f01573123fdaccfe95bf6dcee9… Author: Sergey Kipnis <sergey.kipnis(a)tribe29.com> Date: 2020-11-04 (Wed, 04 Nov 2020) Changed paths: M livestatus/src/Logger.cc M livestatus/src/Logger.h Log Message: ----------- [CMK-6115] - prevent race condition between setHandler and log with mutex This solution is absolutely minimalistic, just to hot fix error and provide easy backporting. Important notes: Hotfix is based on the current algorithm of setHandler/getHandler usage. Performance is comparable. Few nanoseconds per a log entry means almost nothing. Possible improvements for the next commit(or instead): - remove virtual getHandler interface as exposing implementation details - replace virtual Logger::setHandler with non virtual Logger::setHandler - introduce non-virtual Logger::publish interface - introduce non-virtual Logger::setFormatter Change-Id: I2902c06adbbe953611ba9ca0957dca42a2f48bc6
