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.
Robust and effective logging for Python 2 and 3.
Installation:
python -m pip install logzero
from logzero import logger
logger.debug("hello")
logger.info("info")
logger.warning("warn")
logger.error("error")
# This is how you'd log an exception
try:
raise Exception("this is a demo exception")
except Exception as e:
logger.exception(e)
# JSON logging
import logzero
logzero.json()
logger.info("JSON test")
# Start writing into a logfile
logzero.logfile("/tmp/logzero-demo.log")
# Set a minimum loglevel
logzero.loglevel(logzero.WARNING)
This is the output:
Note: You can find more examples in the documentation: https://logzero.readthedocs.io
JSON logging can be enabled for the default logger with logzero.json()
, or with setup_logger(json=True)
for custom loggers:
>>> logzero.json()
>>> logger.info("test")
{"asctime": "2020-10-21 10:42:45,808", "filename": "<stdin>", "funcName": "<module>", "levelname": "INFO", "levelno": 20, "lineno": 1, "module": "<stdin>", "message": "test", "name": "logzero_default", "pathname": "<stdin>", "process": 76179, "processName": "MainProcess", "threadName": "MainThread"}
>>> my_logger = setup_logger(json=True)
>>> my_logger.info("test")
{"asctime": "2020-10-21 10:42:45,808", "filename": "<stdin>", "funcName": "<module>", "levelname": "INFO", "levelno": 20, "lineno": 1, "module": "<stdin>", "message": "test", "name": "logzero_default", "pathname": "<stdin>", "process": 76179, "processName": "MainProcess", "threadName": "MainThread"}
The logged JSON object has these fields:
{
"asctime": "2020-10-21 10:43:40,765",
"filename": "test.py",
"funcName": "test_this",
"levelname": "INFO",
"levelno": 20,
"lineno": 9,
"module": "test",
"message": "info",
"name": "logzero",
"pathname": "_tests/test.py",
"process": 76204,
"processName": "MainProcess",
"threadName": "MainThread"
}
Exceptions logged with logger.exception(e)
have these additional JSON fields:
{
"levelname": "ERROR",
"levelno": 40,
"message": "this is a demo exception",
"exc_info": "Traceback (most recent call last):\n File \"_tests/test.py\", line 15, in test_this\n raise Exception(\"this is a demo exception\")\nException: this is a demo exception"
}
Take a look at the documentation for more information and examples:
Install logzero
with pip:
python -m pip install logzero
Here's how you setup a virtualenv and download and run the demo:
# Create and activate a virtualenv in ./venv/
python3 -m venv venv
. venv/bin/activate
# Install logzero
python -m pip install logzero
# Download and run demo.py
wget https://raw.githubusercontent.com/metachris/logzero/master/examples/demo.py
python demo.py
If you don't have pip installed, this Python installation guide can guide you through the process.
Alternatively, if you use the Anaconda distribution:
$ conda config --add channels conda-forge
$ conda install logzero
You can also install logzero
from the public Github repo:
$ git clone https://github.com/metachris/logzero.git
$ cd logzero
$ python setup.py install
Getting started
$ git clone https://github.com/metachris/logzero.git
$ cd logzero
# Activate virtualenv
$ python3 -m venv venv
$ . venv/bin/activate
# Install main and dev dependencies
$ pip install -e .
$ pip install -r requirements_dev.txt
# Run the tests
$ make test
# Run the linter
$ make lint
# Generate the docs (will auto-open in Chrome)
$ make docs
# You can enable watching mode to automatically rebuild on changes:
$ make servedocs
To test with Python 2.7, you can use Docker:
docker run --rm -it -v /Users/chris/stream/logzero:/mnt python:2.7 /bin/bash
Now you have a shell with the current directory mounted into /mnt/
inside the container.
