Will it work with multiprocessing?

• cool-RR 7y ago
  Good question. If the function is launched in a spawned process, it'll work, though you might have trouble getting the stderr, so you better include a log file as the first argument, like this `@snoop('/var/log/snoop.log')` If the function launches new processes internally... I'm not sure. If you try it and it doesn't work, open an issue: https://github.com/cool-RR/PySnooper/issues https://github.com/cool-RR/PySnooper/issues

    There is a race condition when writting on the same log file from several processes at the same time, which is a typical use case for wsgi frameworks such as django or flask.

      Seems like a "log to this unix domain socket" option could help for those cases? Or one to open a new file for new PIDs?

        Could probably do: @pysnooper.snoop(f"/path/to/file.{os.getpid()}.log") Something like that
