Harshavardhana 76e2713ffe fix: use buffers only when necessary for io.Copy() (#11229) ... Use separate sync.Pool for writes/reads Avoid passing buffers for io.CopyBuffer() if the writer or reader implement io.WriteTo or io.ReadFrom respectively then its useless for sync.Pool to allocate buffers on its own since that will be completely ignored by the io.CopyBuffer Go implementation. Improve this wherever we see this to be optimal. This allows us to be more efficient on memory usage. ``` 385 // copyBuffer is the actual implementation of Copy and CopyBuffer. 386 // if buf is nil, one is allocated. 387 func copyBuffer(dst Writer, src Reader, buf []byte) (written int64, err error) { 388 // If the reader has a WriteTo method, use it to do the copy. 389 // Avoids an allocation and a copy. 390 if wt, ok := src.(WriterTo); ok { 391 return wt.WriteTo(dst) 392 } 393 // Similarly, if the writer has a ReadFrom method, use it to do the copy. 394 if rt, ok := dst.(ReaderFrom); ok { 395 return rt.ReadFrom(src) 396 } ``` From readahead package ``` // WriteTo writes data to w until there's no more data to write or when an error occurs. // The return value n is the number of bytes written. // Any error encountered during the write is also returned. func (a *reader) WriteTo(w io.Writer) (n int64, err error) { if a.err != nil { return 0, a.err } n = 0 for { err = a.fill() if err != nil { return n, err } n2, err := w.Write(a.cur.buffer()) a.cur.inc(n2) n += int64(n2) if err != nil { return n, err } ```		4 years ago
