Root Cause

Attempting to read from or write to an io.Pipe that has already been closed.

generic

中文

尝试在已关闭的 io.Pipe 上进行读取或写入。

Workarounds

  1. 80% success 
    pr, pw := io.Pipe(); defer pw.Close(); // ensure proper close order
  2. 90% success 
    Use sync.Once to close the pipe only once

Dead Ends

Common approaches that don't work:

  1. 100% fail

    Leads to data corruption or panic

  2. 100% fail

    Cannot reopen a closed pipe; need to create a new one
