Value sizes are limited in the AsciiProtocol are limited to 32768

private final val MaxValueSize = 32768

However, by default values can be up to 1MB and with tuning values can be even larger. When the user attempts to write a larger value it works fine, but when they read that larger value they simply get a mysterious error such as:

SEVERE: com.dongxiguo.memcontinuationed.ProtocolException: Bad line VALUE raw:6TSa2041BHDwSWYtJA0+dmZvRNg= 0 168508

Hi,
If i send much conccurent requests to my application, I have an exception :
2013-08-08 17-40-19 C:\Users\atry\Documents\lalala\game\race-for-the-woolen\commons-continuations\src\main\scala\com\dongxiguo\commons\continuations\io\AsynchronousInputStream.scala:45 completed
SEVERE: Exception is thrown in continuation when handling a completed asynchronous reading. java.nio.BufferUnderflowException
at java.nio.Buffer.nextGetIndex(Buffer.java:492)
at java.nio.HeapByteBuffer.get(HeapByteBuffer.java:135)

I use linux system and not windows

It seems like authenticated MemCache isn't currently supported. It would be great to have this. Thanks!

I think the dependency part of the README can be simplified to:

libraryDependencies <++= scalaBinaryVersion {
  case "2.10" =>
    Seq()
  case _ =>
    Seq("org.scala-lang.plugins" %% "scala-continuations-library" % "1.0.1")
}

The binary protocol is proported to be faster, but memcontinuationed currently only uses the ASCII protocol.

I wish get key in memcache and if not found then add data in memcache and return data.

def getOrData[T](key: String, duration: Int = 10)(data: => T): Future[T] = {
reset {
memcached.get(Key(key)).get(Key(key)) match {
case None => {
memcached.add[Array[Byte]](Key%28key%29, Serialize.serialize%28data%29, Exptime.fromNowOn%28duration%29)
Future(data)
}
case Some(result) => {
Future(Serialize.unserializeT)
}
case _ =>
}
}
}

I don't have any problem with serialize and un unserialize method, this method take an Array of Byte and return T object.

But I have errors with my implementation :
scala.util.continuations.cpsParam[Unit,Unit] is not a subtype of scala.util.continuations.cpsParam[?,scala.concurrent.Future[T]]
[error] case None => {

illegal answer type modification: scala.util.continuations.cpsParam[Unit,Unit] andThen scala.util.continuations.cpsParam[?,scala.concurrent.Future[T]]
[error] memcached.get(Key(key)).get(Key(key)) match {

if I add addCompilerPlugin("org.scala-lang.plugins" % "continuations" % "2.10.2") in my build.scala, I have this error :
java.lang.NoClassDefFoundError: scala/reflect/internal/AnnotationCheckers$AnnotationChecker

error java.lang.reflect.InvocationTargetException

But if I change the version of this plugin to 2.9.2, I don't have this error but I have some errors in my code because not found method require, add get etc (probably because scala 2.9.2)

Application has build with sbt 1.12.4 and scala 2.10.2

I'm trying to clone memcontinuationed and then run it in sbt. I get the following unresolved dependencies that prevent it from running:
