Malicious npm Package Targets Solana Developers and Hijacks Funds
A malicious npm package targets Solana developers, rerouting funds in 2% of transactions to a hardcoded address.
multiprocessing-logging
Advanced tools
When using the multiprocessing
module, logging becomes less useful since
sub-processes should log to individual files/streams or there's the risk of
records becoming garbled.
This simple module implements a Handler
that when set on the root
Logger
will handle tunneling the records to the main process so that
they are handled correctly.
It's currently tested in Linux and Python 2.7 & 3.6+.
Pypy3 hangs on the tests so I don't recommend using it.
Pypy appears to be working, recently.
Only works on POSIX systems and only Linux is supported. It does not work on Windows.
This library was taken verbatim from a StackOverflow post and extracted into a module so that I wouldn't have to copy the code in every project.
Later, several improvements have been contributed.
Before you start logging but after you configure the logging framework (maybe with logging.basicConfig(...)
), do the following:
import multiprocessing_logging
multiprocessing_logging.install_mp_handler()
and that's it.
When using a Pool, make sure install_mp_handler
is called before the Pool is instantiated, for example:
import logging
from multiprocessing import Pool
from multiprocessing_logging import install_mp_handler
logging.basicConfig(...)
install_mp_handler()
pool = Pool(...)
The approach of this module relies on fork being used to create new processes. This start method is basically unsafe when also using threads, as this module does.
The consequence is that there's a low probability of the application hanging when creating new processes.
As a palliative, don't continuously create new processes. Instead, create a Pool once and reuse it.
