New submission from Adrien <delgan...@gmail.com>:
Hi. I noticed that there exists the function "threading.main_thread()", but there is no equivalent for the "multiprocessing" module. Is there a reason for this absence? These StackOverflow questions are related to this problem: - https://stackoverflow.com/questions/42283265/how-to-determine-if-running-current-process-is-parent - https://stackoverflow.com/questions/30790660/python-multiprocessing-name-of-the-main-process - https://stackoverflow.com/questions/18216050/is-there-a-way-to-check-if-a-module-is-being-loaded-by-multiprocessing-standard Current proposed solutions have flaws. It's suggested to check if "current_process().name == 'MainProcess'" but anyone can re-write the name of a process with "current_process().name = 'foobar'" so this does not seem to be a reliable solution. Another alternative is to check for the type of the process, which is different for main and child, respectively "mulitprocessing.process._MainProcess" and "multiprocessing.process.Process". This is obviously hacky as it relies on implementation detail. What are you thoughts on adding a new "multiprocessing.main_process()" function? ---------- components: Library (Lib) messages: 354918 nosy: Delgan priority: normal severity: normal status: open title: There is no proper way to know if a process is the main one type: enhancement _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38520> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
