Overview

Sync-stream

This project is designed for providing the synchoronization of the stdout / stderr among different threads, processes, devices or hosts. The package could be used for the following cases:

  1. Use syncstream.LineBuffer: Multiple threads are created. The messages (stdout) from different threads are required to be collected.
  2. Use syncstream.LineProcBuffer in the main process, and syncstream.LineProcMirror in the sub-processes: Multiple sub-processes are created on the same device. The stdout / stderr of each process is redirected to a LineProcMirror, and the results are collected by LineProcBuffer.
  3. Use syncstream.LineFileBuffer: Multiple processes are created. These processes may be deployed on different devices (even with different platforms), but all devices could get accessed to the same shared disk. In this case, the message could be shared by locked files. Each process would hold an independent LineFileBuffer pointing to the same log files.
  4. Use syncstream.LineHostBuffer on the server side, and syncstream.LineHostMirror on the client side: Multiple processes are deployed on different devices, and they could not share the same disk. In this case, the message are synchronized by the web service. Each process would hold a LineHostMirror, and the results would be collected by LineHostBuffer.

The basic package would not contain the file and host modules. To install the package, please use the following options:

pip install syncstream[option1,option2...]
Option Supports
file Install dependencies for the file module. The module provides syncstream.LineFileBuffer.
host Install dependencies for the host module. The module provides syncstream.LineHostBuffer, and syncstream.LineHostMirror.
