readByteArray is broken

[altavir]

kotlinx-io/core/commonMain/src/kotlinx/io/InputOperations.kt

Lines 64 to 65 in 2b54f00

	var position = size
	while (position < size) {

This two statements together mean that returned array is always empty and pointer not advanced. I recommend adding tests for that.

Even after my fix, the method is still broken. By contract, this method:

kotlinx-io/core/commonMain/src/kotlinx/io/InputOperations.kt

Lines 66 to 71 in fe899e0

	val count = readBufferRange { buffer, startOffset, endOffset ->
	val length = min(endOffset - startOffset, size - position)
	buffer.copyTo(result, startOffset, length, position)
	length
	}

should return the position after read (I don't know how it meant to know the position - it is private), but returns the number of bytes being read, so it works only when we are reading at the beginning of new buffer. Any suggestions?

We're rebooting the kotlinx-io development (see #131), all issues related to the previous versions will be closed. Consider reopening it if the issue remains (or the feature is still missing) in a new version.
