Avoid recorder for io.ReadSeeker in anyio.NewReaderWithOpts#4790
Merged
Conversation
NewReaderWithOpts always creates a Recorder, which buffers its input and can cause format detection to fail if the buffer is too small. Avoid that problem when the passed reader implements io.ReadSeeker by modifying Track to create a Recorder only when the reader cannot seek. Closes #4586.
