decodeFromBufferedSource throws JsonDecodingException on big JSON #2006
Description
Describe the bug
Trying to use new Okio streams, introduced recently and encountering JsonDecodingException when trying to decode big JSON via decodeFromBufferedSource().
decodeFromString() works fine.
To Reproduce
@Serializable
data class Node(
val children: List<Node>?
)
fun test() {
fun getNodes(count: Int, depth: Int) : List<Node> {
val ret = mutableListOf<Node>()
if (depth == 0) return ret
for (i in 0 until count) {
ret.add(Node(getNodes(1, depth - 1)))
}
return ret
}
val rootNode = Node(getNodes(1000, 10))
val json = Serializer.json.encodeToString(rootNode)
val buffer = okio.Buffer().apply {
write(json.toByteArray())
}
// val decodedNode = Serializer.json.decodeFromString<Node>(json) // works fine
val decodedNode = Serializer.json.decodeFromBufferedSource<Node>(buffer) // throws JsonDecodingException
}
Exception error:
kotlinx.serialization.json.internal.JsonDecodingException: Expected colon ':', but had 'EOF' instead at path: $.children[107].children[0].children[108]
JSON input: .....hildren":[{"children":[{"children":[{"children":[{"children"
I've created github repository with reproducible example: https://github.com/Artman12/OkioTest
Expected behavior
decodeFromBufferedSource decodes JSON correctly.
