Root Cause

An io.Reader returned fewer bytes than requested without returning an error, violating the io.Reader contract.

generic

中文

io.Reader 返回的字节数少于请求数且未返回错误，违反了 io.Reader 契约。

Workarounds

  1. 95% success 
    Use io.ReadFull to ensure the exact number of bytes are read.
  2. 90% success 
    Loop over io.Read until the desired count is reached or an error occurs.

Dead Ends

Common approaches that don't work:

  1. 95% fail

    This leads to data corruption and undefined behavior.

  2. 80% fail

    The buffer size doesn't affect the reader's behavior; it may still return short reads.
