sigdump 0.0.1

用法

以下是一个启用sigdump的服务器示例

import os
from wsgiref.simple_server import make_server

import sigdump


def application(env, start_response):
    start_response('200 OK', [('Content-type', 'text/plain; charset=utf-8')])
    return [b'Hello World']


if __name__ == '__main__':
    sigdump.enable(verbose=True)  # just calling sigdump.signal()

    print("pid:", os.getpid())
    httpd = make_server('', 8000, application)
    httpd.serve_forever()

$ python example/wsgi.py
pid: 57650
SIGDUMP is enabled. The result is exported to /tmp/sigdump-82323.log.

然后发送一个 SIGCONT 信号。如果您想更改信号，请设置 SIGDUMP_SIGNAL 环境变量。

$ kill -s SIGCONT 57650

请查看 /tmp/sigdump-<pid>.log。如果您想更改输出路径，请设置 SIGDUMP_PATH 环境变量。您可以将 "-" 设置为将输出到 STDOUT，或 "+" 设置为 STDERR。

$ less /tmp/sigdump-57650.log
Sigdump at 2019-12-06 21:04:55.071633 process 57650
