okio v1.3.0 Release Notes

  • 2015-03-16

    • New: Read and write signed decimal and unsigned hexadecimal values in BufferedSource and BufferedSink. Unlike the alternatives, these methods don’t do any memory allocations!
    • New: Segment sharing. This improves the runtime of operations like Buffer.clone() and Buffer.copyTo() by sharing underlying segments between buffers.
    • New: Buffer.snapshot() returns an immutable snapshot of a buffer as a ByteString. This builds on segment sharing so that snapshots are shallow, immutable copies.
    • New: ByteString.rangeEquals().
    • New: ByteString.md5() and ByteString.sha256().
    • New: ByteString.base64Url() returns URL-safe Base64. The existing decoding method has been extended to support URL-safe Base64 input.
    • New: ByteString.substring() returns a prefix, infix, or suffix.
    • New: Sink now implements java.io.Flushable.
    • Fix: Buffer.write(Source, long) now always writes fully. The previous behavior would return as soon as any data had been written; this was inconsistent with all other write() methods in the API.
    • Fix: don't leak empty segments in DeflaterSink and InflaterSource. (This was unlikely to cause problems in practice.)
