+under the License.
+
+Building and installing from source
+===================================
+
+When using a CMake build from the source distribution on Linux the
+easiest way to build and install is this simple command line:
+
+    make all && sudo make install/fast
+
+It is important to use the install/fast option to eliminate
+the automatic rebuild by dependency that causes issues because
+the build tooling is designed to work with cached files in the
+user home directory during the build process. Instead this builds
+the code in the expected local build tree and then uses CMake
+install code to copy to the target destination.
+
+Building Thrift with Gradle without CMake/Autoconf
+==================================================
+
+The Thrift Java source is not build using the GNU tools, but rather uses
+the Gradle build system, which tends to be predominant amongst Java
+developers.
+
+To compile the Java Thrift libraries, simply do the following:
+
+    ./gradlew
+
+Yep, that's easy. Look for libthrift-<version>.jar in the build/libs directory.
+
+The default build will run the unit tests which expect a usable
+Thrift compiler to exist on the system. You have two choices for
+that.
+
+* Build the Thrift executable from source at the default
+  location in the source tree. The project is configured
+  to look for it there.
+* Install the published binary distribution to have Thrift
+  executable in a known location and add the path to the
+  ~/.gradle/gradle.properties file using the property name
+  "thrift.compiler". For example this would set the path in
+  a Windows box if Thrift was installed under C:\Thrift
+
+    thrift.compiler=C:/Thrift/thrift.exe
+
+To just build the library without running unit tests you simply do this.
+
+    ./gradlew assemble
+
+To install the library in the local Maven repository location
+where other Maven or Gradle builds can reference it simply do this.
+
+    ./gradlew install
+
+The library will be placed in your home directory under .m2/repository
+
+To include Thrift in your applications simply add libthrift.jar to your
+classpath, or install if in your default system classpath of choice.
+
+
+Build Thrift behind a proxy:
+
+    ./gradlew -Dhttp.proxyHost=myproxyhost -Dhttp.proxyPort=8080 -Dhttp.proxyUser=thriftuser -Dhttp.proxyPassword=topsecret
+
+or via
+
+    ./configure --with-java GRADLE_OPTS='-Dhttp.proxyHost=myproxyhost -Dhttp.proxyPort=8080 -Dhttp.proxyUser=thriftuser -Dhttp.proxyPassword=topsecret'
+
+
+Unit Test HTML Reports
+======================
+
+The build will automatically generate an HTML Unit Test report. This can be found
+under build/reports/tests/test/index.html. It can be viewed with a browser
+directly from that location.
+
+
+Clover Code Coverage for Thrift
+===============================
+
+The build will optionally generate Clover Code coverage if the Gradle property
+`cloverEnabled=true` is set in ~/.gradle/gradle.properties or on the command line
+via `-PcloverEnabled=true`. The generated report can be found under the location
+build/reports/clover/html/index.html. It can be viewed with a browser
+directly from that location. Additionally, a PDF report is generated and is found
+under the location build/reports/clover/clover.pdf.
+
+The following command will build, unit test, and generate Clover reports:
+
+    ./gradlew -PcloverEnabled=true
+
+
+Publishing Maven Artifacts to Maven Central
+===========================================
+
+The Automake build generates a Makefile that provides the correct parameters
+when you run the build provided the configure.ac has been set with the correct
+version number. The Gradle build will receive the correct value for the build.
+The same applies to the CMake build, the value from the configure.ac file will
+be used if you execute these commands:
+
+    make maven-publish   -- This is for an Automake Linux build
+    make MavenPublish    -- This is for a CMake generated build
+
+The uploadArchives task in Gradle is preconfigured with all necessary details
+to sign and publish the artifacts from the build to the Apache Maven staging
+repository. The task requires the following externally provided properties to
+authenticate to the repository and sign the artifacts. The preferred approach
+is to create or edit the ~/.gradle/gradle.properties file and add the following
+properties to it.
+
+    # Signing key information for artifacts PGP signature (values are examples)
+    signing.keyId=24875D73
+    signing.password=secret
+    signing.secretKeyRingFile=/Users/me/.gnupg/secring.gpg
+
+    # Apache Maven staging repository user credentials
+    mavenUser=meMyselfAndI
+    mavenPassword=MySuperAwesomeSecretPassword
+
+NOTE: If you do not have a secring.gpg file, see the
+[gradle signing docs](https://docs.gradle.org/current/userguide/signing_plugin.html)
+for instructions on how to generate it.
+
+It is also possible to manually publish using the Gradle build directly.
+With the key information and credentials in place the following will generate
+if needed the build artifacts and proceed to publish the results.
+
+    ./gradlew -Prelease=true uploadArchives
+
+It is also possible to override the target repository for the Maven Publication
+by using a Gradle property, for example you can publish signed JAR files to your
+company internal server if you add this to the command line or in the
+~/.gradle/gradle.properties file. The URL below assumes a Nexus Repository.
+
+    maven-repository-url=https://my.company.com/service/local/staging/deploy/maven2
+
+Or the same on the command line:
+
+    ./gradlew -Pmaven-repository-url=https://my.company.com/service/local/staging/deploy/maven2 -Prelease=true -Pthrift.version=0.11.0 uploadArchives
+
+
+Dependencies
+============
+
+Gradle
+http://gradle.org/
+
+# Breaking Changes
+
+## 0.13.0
+
+* The signature of the 'process' method in TAsyncProcessor and TProcessor has
+changed to remove the boolean return type and instead rely on Exceptions.
+
+* Per THRIFT-4805, TSaslTransportException has been removed. The same condition
+is now covered by TTansportException, where `TTransportException.getType() == END_OF_FILE`.
+ 
+## 0.12.0
+
+The access modifier of the AutoExpandingBuffer class has been changed from
+public to default (package) and will no longer be accessible by third-party
+libraries.
+
+The access modifier of the ShortStack class has been changed from
+public to default (package) and will no longer be accessible by third-party
+libraries.

+/**
+ * This class uses a single thread to set up non-blocking sockets to a set
+ * of remote servers (hostname and port pairs), and sends a same request to
+ * all these servers. It then fetches responses from servers.
+ *
+ * Parameters:
+ *   int maxRecvBufBytesPerServer - an upper limit for receive buffer size
+ * per server (in byte). If a response from a server exceeds this limit, the
+ * client will not allocate memory or read response data for it.
+ *
+ *   int fetchTimeoutSeconds - time limit for fetching responses from all
+ * servers (in second). After the timeout, the fetch job is stopped and
+ * available responses are returned.
+ *
+ *   ByteBuffer requestBuf - request message that is sent to all servers.
+ *
+ * Output:
+ *   Responses are stored in an array of ByteBuffers. Index of elements in
+ * this array corresponds to index of servers in the server list. Content in
+ * a ByteBuffer may be in one of the following forms:
+ *   1. First 4 bytes form an integer indicating length of following data,
+ * then followed by the data.
+ *   2. First 4 bytes form an integer indicating length of following data,
+ * then followed by nothing - this happens when the response data size
+ * exceeds maxRecvBufBytesPerServer, and the client will not read any
+ * response data.
+ *   3. No data in the ByteBuffer - this happens when the server does not
+ * return any response within fetchTimeoutSeconds.
+ *
+ *   In some special cases (no servers are given, fetchTimeoutSeconds less
+ * than or equal to 0, requestBuf is null), the return is null.
+ *
+ * Note:
+ *   It assumes all remote servers are TNonblockingServers and use
+ * TFramedTransport.

+/**
+ * HTTP implementation of the TTransport interface. Used for working with a
+ * Thrift web services implementation (using for example TServlet).
+ *
+ * This class offers two implementations of the HTTP transport.
+ * One uses HttpURLConnection instances, the other HttpClient from Apache
+ * Http Components.
+ * The chosen implementation depends on the constructor used to
+ * create the THttpClient instance.
+ * Using the THttpClient(String url) constructor or passing null as the
+ * HttpClient to THttpClient(String url, HttpClient client) will create an
+ * instance which will use HttpURLConnection.
+ *
+ * When using HttpClient, the following configuration leads to 5-15% 
+ * better performance than the HttpURLConnection implementation:
+ *
+ * http.protocol.version=HttpVersion.HTTP_1_1
+ * http.protocol.content-charset=UTF-8
+ * http.protocol.expect-continue=false
+ * http.connection.stalecheck=false
+ *
+ * Also note that under high load, the HttpURLConnection implementation
+ * may exhaust the open file descriptor limit.
+ *
