From 3f324e21fd54b58ed130e11b49898b10ff40b8c3 Mon Sep 17 00:00:00 2001 From: dan mcweeney Date: Wed, 11 Dec 2019 12:01:39 -0500 Subject: [PATCH] Tighten up handling of a read of the params. Broke reading the kafka protocol into a new method to keep the strict parsing of the scheme intact. Use only base64 encoded keys. --- .../openwhisk/core/entity/Parameter.scala | 107 +++++++++++------- .../core/entity/ParameterEncryption.scala | 31 +++-- .../core/containerpool/ContainerProxy.scala | 2 +- .../controller/test/ActionsApiTests.scala | 65 ++++++----- .../test/ParameterEncryptionTests.scala | 96 ++++++++++++---- 5 files changed, 195 insertions(+), 106 deletions(-) diff --git a/common/scala/src/main/scala/org/apache/openwhisk/core/entity/Parameter.scala b/common/scala/src/main/scala/org/apache/openwhisk/core/entity/Parameter.scala index d38dbb8a61e..c01a0fa08ee 100644 --- a/common/scala/src/main/scala/org/apache/openwhisk/core/entity/Parameter.scala +++ b/common/scala/src/main/scala/org/apache/openwhisk/core/entity/Parameter.scala @@ -21,6 +21,7 @@ import org.apache.openwhisk.core.entity.size.{SizeInt, SizeString} import spray.json.DefaultJsonProtocol._ import spray.json._ +import scala.collection.immutable.ListMap import scala.language.postfixOps import scala.util.{Failure, Success, Try} @@ -93,7 +94,8 @@ protected[core] class Parameters protected[entity] (private val params: Map[Para case (JsNull) => None case _ => Some("encryption" -> p._2.encryption.toJson) } - JsObject(Map("key" -> p._1.name.toJson, "value" -> p._2.value.toJson) ++ init ++ encrypt) + // Have do use this slightly strange construction to get the json object order identical. + JsObject(ListMap() ++ encrypt ++ init ++ Map("key" -> p._1.name.toJson, "value" -> p._2.value.toJson)) } toSeq: _*) } @@ -146,7 +148,7 @@ protected[core] class Parameters protected[entity] (private val params: Map[Para /** * A ParameterName is a parameter name for an action or trigger to bind to its environment. - * It wraps a normalized string as a value type. + * It wraps a normalized string as a valueread type. * * It is a value type (hence == is .equals, immutable and cannot be assigned null). * The constructor is private so that argument requirements are checked and normalized @@ -215,7 +217,7 @@ protected[core] object Parameters extends ArgNormalizer[Parameters] { protected[core] def apply(p: String, v: String, init: Boolean = false): Parameters = { require(p != null && p.trim.nonEmpty, "key undefined") Parameters() + (new ParameterName(ArgNormalizer.trim(p)), - ParameterValue(Option(v).map(_.trim.toJson).getOrElse(JsNull), init)) + ParameterValue(Option(v).map(_.trim.toJson).getOrElse(JsNull), init, JsNull)) } /** @@ -231,7 +233,7 @@ protected[core] object Parameters extends ArgNormalizer[Parameters] { protected[core] def apply(p: String, v: JsValue, init: Boolean): Parameters = { require(p != null && p.trim.nonEmpty, "key undefined") Parameters() + (new ParameterName(ArgNormalizer.trim(p)), - ParameterValue(Option(v).getOrElse(JsNull), init)) + ParameterValue(Option(v).getOrElse(JsNull), init, JsNull)) } /** @@ -246,9 +248,30 @@ protected[core] object Parameters extends ArgNormalizer[Parameters] { protected[core] def apply(p: String, v: JsValue): Parameters = { require(p != null && p.trim.nonEmpty, "key undefined") Parameters() + (new ParameterName(ArgNormalizer.trim(p)), - ParameterValue(Option(v).getOrElse(JsNull), false)) + ParameterValue(Option(v).getOrElse(JsNull), false, JsNull)) } + def readMergedList(value: JsValue): Parameters = + Try { + val JsObject(obj) = value + new Parameters( + obj + .map((tuple: (String, JsValue)) => { + val key = new ParameterName(tuple._1) + val paramVal: ParameterValue = tuple._2 match { + case o: JsObject => + o.getFields("value", "init", "encryption") match { + case Seq(v: JsValue, JsBoolean(i), e: JsValue) => + ParameterValue(v, i, e) + case _ => ParameterValue(o, false, JsNull) + } + case v: JsValue => ParameterValue(v, false, JsNull) + } + (key, paramVal) + }) + .toMap) + } getOrElse deserializationError("parameters malformed, could not get a JsObject from: " + (if (value != null) value.toString() else "")) + override protected[core] implicit val serdes = new RootJsonFormat[Parameters] { def write(p: Parameters) = p.toJsArray @@ -266,25 +289,22 @@ protected[core] object Parameters extends ArgNormalizer[Parameters] { } flatMap { read(_) } getOrElse { - // Used when the container proxy is reading back a merged version of the params.
