Root Cause

An I/O read returned 0 bytes without an error, which is unexpected and may indicate a bug in the reader implementation.

generic

中文

I/O读取返回0字节但没有错误，这是意外的，可能表示读取器实现中的错误。

Workarounds

  1. 90% success Check for zero-length reads and treat as error 
    n, err := reader.Read(buf)
if n == 0 && err == nil { return errors.New("zero-length read") }

Dead Ends

Common approaches that don't work:

  1. Assuming it's a transient error 70% fail

    May cause infinite loop if retried; check for zero-length reads.
