根因分析

在读取端关闭后写入管道，通常由于读取器过早关闭。

English

Writing to a pipe after the read end has been closed, often due to premature closure of the reader.

generic

解决方案

  1. 90% 成功率 Use io.Pipe with proper error handling and synchronization 
    pr, pw := io.Pipe()
// writer goroutine
go func() {
    defer pw.Close()
    _, err := pw.Write(data)
    if err != nil { log.Println(err) }
}()
// reader
data, err := io.ReadAll(pr)

无效尝试

常见但无效的做法:

  1. Ignoring SIGPIPE signal 60% 失败

    Signal handling may not prevent panic; use proper synchronization.
