+| Let’s look at how to deploy **VeriGraph** on Apache Tomcat. If you’re
+ only interested in creating gRPC API and ``neo4jmanager`` is already
+ deployed, you can skip this section and go straight to the
+ `documentation <https://gitlab.com/serena.spinoso/DP2.2017.SpecialProject2.gRPC/tree/master/src/main/java/it/polito/grpc>`__
+| (though you might find it useful if Tomcat is not yet installed!).
+
+**Windows**
+
+- install ``jdk1.8.X_YY``
+ `here <http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html>`__
+- set ambient variable ``JAVA_HOME`` to where you installed the jdk
+ (e.g. ``C:\Program Files\Java\jdk1.8.X_YY``)
+- install Apache Tomcat 8
+ `here <https://tomcat.apache.org/download-80.cgi>`__
+- install a pre-compiled distribution of Z3 from
+ `here <https://github.com/Z3Prover/bin/tree/master/releases>`__
+ and save the ``[z3_root]/bin`` content under ``[verigraph]/service/build``
+- create the ``mcnet.jar`` of the ``mcnet.*`` packages and put into the ``[verigraph]/service/build`` directory
+- download the qjutils library
+ `here <https://github.com/quanla/classreloading/tree/master/src/main/java/qj/util>`__
+ and create a jar file (i.e. qjutils.jat) in ``[verigrap]/service/build``
+- set ambient variable ``CATALINA_HOME`` to the directory where you
+ installed Apache (e.g.
+ ``C:\Program Files\Java\apache-tomcat-8.0.30``)
+- create ``shared`` folder under ``%CATALINA_HOME%``
+- add previously created folder to the Windows ``Path`` system variable
+ (i.e. append the following string at the end:
+ ``;%CATALINA_HOME%\shared``)
+- copy ``[verigraph]/lib/mcnet.jar``, ``[verigraph]/service/build/com.microsoft.z3.jar`` and ``[verigraph]/service/build/qjutils.jar``
+ to ``%CATALINA_HOME%\shared``
+- to correctly compile the code you have to put the path of ``com.microsoft.z3.jar``
+ and the libraries it refers to as environment variable. i.e. is enough
+ to add the project subfolder ``build`` to the PATH environment variable (i.e., ``[verigraph]/build``)
+- create custom file setenv.bat under ``%CATALINA_HOME%\bin`` with the
+ following content:
+
+ .. code:: bat
+
+ set CLASSPATH=%CLASSPATH%;%CATALINA_HOME%\shared\qjutils.jar;%CATALINA_HOME%\shared\mcnet.jar;%CATALINA_HOME%\shared\com.microsoft.z3.jar;.;%CATALINA_HOME%\webapps\verify\WEB-INF\classes\tests
+
+- download ``neo4jmanager.war`` from
+ `here <https://github.com/netgroup-polito/verigraph/tree/master/dist>`__
+ and copy into into ``%CATALINA_HOME%\webapps``
+- export the ``verify.war`` file from the project and copy into ``%CATALINA_HOME%\webapps``
+- (optional) configure Tomcat Manager:
+- open the file ``%CATALINA_HOME%\conf\tomcat-users.xml``
+- under the ``tomcat-users`` tag place the following content:
+ ``xml <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="tomcat" roles="tomcat,manager-gui"/> <user username="both" password="tomcat" roles="tomcat,role1"/> <user username="role1" password="tomcat" roles="role1"/>``
+- launch Tomcat 8 with the startup script
+ ``%CATALINA_HOME%\bin\startup.bat``
+- (optional) if you previously configured Tomcat Manager you can open a
+ browser and navigate to `this link <http://localhost:8080/manager>`__
+ and login using ``tomcat/tomcat`` as username/password
+- (optional) you can deploy/undeploy/redeploy the downloaded WARs
+ through the web interface
+
+**Unix**
+
+- install ``jdk1.8.X_YY`` from the command line:
+- go to `this
+ link <http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html>`__
+ to check the appropriate version for you OS and architecture
+- copy the desired version to the clipboard (e.g.
+ ``http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz``)
+- open a terminal windows and paste the following command (replace
+ ``link`` with the previously copied link):
+ ``wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" 'link'``
+ e.g.
+ ``wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/7u79-b15/jdk-7u79-linux-x64.tar.gz``
+- untar the archive with the following command (replace 'jdk' to match
+ the name of the downloaded archive):
+ ``tar zxvf 'jdk'.tar.gz``
+ e.g.
+ ``tar zxvf jdk-7u<version>-linux-x64.tar.gz``
+- delete the ``.tar.gz`` file if you want to save disk space
+- install and configure Apache Tomcat 8 with the following commands:
+- go to `this URL <http://it.apache.contactlab.it/tomcat/tomcat-8/>`__
+ and see what the latest available version is
+- download the archive (substitute every occurrence of '8.0.32' in the
+ following command with the latest available version):
+ ``wget http://it.apache.contactlab.it/tomcat/tomcat-8/v8.0.32/bin/apache-tomcat-8.0.32.tar.gz``
+- extract downloaded archive:
+ ``tar xvf apache-tomcat-8.0.32.tar.gz``
+- edit configuration:
+ ``nano ./apache-tomcat-8.0.32/conf/tomcat-users.xml``
+- under the ``tomcat-users`` tag place the following content
+ ``xml <role rolename="tomcat"/> <role rolename="role1"/> <user username="tomcat" password="tomcat" roles="tomcat,manager-gui"/> <user username="both" password="tomcat" roles="tomcat,role1"/> <user username="role1" password="tomcat" roles="role1"/> </tomcat-users>``
+- set a few environment variables:
+ ``sudo nano ~/.bashrc``
+- paste the following content at the end of the file
+ ``export CATALINA_HOME='/path/to/apache/tomcat/folder'``
+ e.g.
+ ``export CATALINA_HOME=/home/mininet/apache-tomcat-8.0.33``
+ ``export JRE_HOME='/path/to/jdk/folder'``
+ e.g.
+ ``export JRE_HOME=/home/mininet/jdk1.8.0_92/jre``
+ ``export JDK_HOME='/path/to/jdk/folder'``
+ e.g.
+ ``export JDK_HOME=/home/mininet/jdk1.8.0_92``
+ ``export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CATALINA_HOME/shared``
+ ``export JAVA_OPTS="-Djava.library.path=$CATALINA_HOME/shared"``
+- ``exec bash``
+- install a pre-compiled distribution of Z3 from
+ `here <https://github.com/Z3Prover/bin/tree/master/releases>`__
+ and save [z3_root]/bin content under ``[verigraph]/service/build``
+- download the qjutils library
+ `here <https://github.com/quanla/classreloading/tree/master/src/main/java/qj/util>`__
+ and create a jar file (i.e. qjutils.jar) in ``[verigrap]/service/build``
+- create the ``mcnet.jar`` of the ``mcnet.*`` packages and put into the ``[verigraph]/service/build`` directory
+- copy ``[verigraph]/service/build/mcnet.jar``, ``[verigraph]/service/build/com.microsoft.z3.jar``
+ and ``[verigraph]/service/build/qjutils.jar`` to ``$CATALINA_HOME/shared``
+- customize Tomcat classpath
+ ``nano $CATALINA_HOME/bin/setenv.sh``
+- paste the following content and save file:
+ ``bash #!/bin/sh export CLASSPATH=$CLASSPATH:$CATALINA_HOME/shared/qjutils.jar:$CATALINA_HOME/shared/mcnet.jar:$CATALINA_HOME/shared/com.microsoft.z3.jar:.:$CATALINA_HOME/webapps/verify/WEB-INF/classes/tests``
+- save and close the file (``CTRL+O``, ``CTRL+X``)
+ ``sudo chmod +x $CATALINA_HOME/bin/setenv.sh``
+- download ``neo4jmanager.war`` from
+ `here <https://github.com/netgroup-polito/verigraph/tree/master/dist>`__
+ and copy into into ``%CATALINA_HOME%\webapps``
+- export the ``verify.war`` file from the project and copy into ``%CATALINA_HOME%\webapps``
+- launch Tomcat 8 with the startup script
+ ``$CATALINA_HOME/bin/startup.sh``
+- open a browser and navigate to `this
+ link <http://localhost:8080/manager>`__ and login using
+ ``tomcat/tomcat`` as username/password
+- you can deploy/undeploy/redeploy the downloaded WARs through the web
+ interface
+
+**Eclipse**
+
+- clone project onto your hard drive with this command:
+ ``git clone git@github.com:netgroup-polito/verigraph.git``
+- Download Apache Tomcat 8 (see instructions above for Windows and
+ Unix)
+- Download JDK (see instructions above for Windows and Unix)
+- Configure runtime environment in Eclipse with `the following
+ incstructions <http://crunchify.com/step-by-step-guide-to-setup-and-install-apache-tomcat-server-in-eclipse-development-environment-ide/>`__
+- Add new Tomcat server on port ``8080``
+- Configure Tomcat server:
+
+ - double-click on the newly created server in the ``Servers`` tab
+ - make sure under ``Server Locations`` ``Use Tomcat installation``
+ is selected
+ - Open ``Launch Configuration``->``Classpath``
+ - add the required JARS (``mcnet.jar``, ``com.microsoft.z3.jar`` and
+ ``qjutils.jar``) under ``User Entries``
+ - Hit ``Apply`` and ``Ok``
+
+- Run the server
+
+**How to add you own function ``<type>``**
+
+#. under the the ``mcnet.netobjs`` package (i.e. under
+ ``/verify/service/src/mcnet/netobjs``) create a new class
+ ``<Type>.java``, where ``<type>`` is the desired function name (i.e.
+ ``<type>`` will be added to the supported node functional types)
+ which extends ``NetworkObject`` and implement the desired logic
+
+#. regenerate ``mcnet.jar`` selecting the packages ``mcnet.components``
+ and ``mcnet.netobjs`` and exporting the generated JAR to
+ ``/verify/service/build`` (overwrite the existing file)
+
+#. under ``/verify/src/main/webapp/json/`` create a file
+ ``<type>.json``. This file represents a JSON schema (see
+ `here <http://json-schema.org/>`__ the official documentation). For
+ compatibility with the other functions it is mandatory to support an
+ array as the root of the configuration, but feel free to specify all
+ the other constraints as needed. A sample of ``<type>.json`` to
+ describe an empty configuration could be the following:
+
+``json { "$schema": "http://json-schema.org/draft-04/schema#", "title": "Type", "description": "This is a generic type", "type": "array", "items": { "type": "object" }, "minItems": 0, "maxItems": 0, "uniqueItems": true }``
+
+#. in the package ``it.polito.escape.verify.validation`` (i.e. under
+ ``src/main/java/it/polito/escape/verify/validation``) create a new
+ class file named ``<Type>Validator.java`` (please pay attention to
+ the naming convention here: ``<Type>`` is the function type used in
+ the previous step capitalized, followed by the suffix ``Validator``)
+ which implements ``ValidationInterface``. This class represents a
+ custom validator for the newly introduced type and allows for more
+ complex constraints, which is not possible to express through a JSON
+ schema file. The validate method that has to be implemented is given
+ the following objects:
+
+- ``Graph graph`` represents the nffg that the object node belongs to;
+- ``Node node`` represents the node that the object configuration
+ belongs to;
+- ``Configuration configuration`` represents the parsed configuration.
+ It is sufficient to call the method ``getConfiguration`` on the
+ ``configuration`` object to get a ``JsonNode`` (Jackson's class) and
+ iterate over the various fields.
+ In case a configuration is not valid please throw a new
+ ``ValidationException`` passing a descriptive failure message.
+ Adding a custom validator is not strictly necessary whenever a JSON
+ schema is thought to be sufficient. Note though that, other than the
+ mandatory validation against a schema, whenever a custom validator is
+ not found a default validation is triggered, i.e. the value of every
+ JSON property must refer to the name of an existing node in the
+ working graph/nffg. If this is not the desired behavior it is
+ suggested to write a custom validator with looser constraints.
+
+#. customize the class generator and add the support for the newly
+ introduced type:
+
+- open the file
+ ``/verify/service/src/tests/j-verigraph-generator/config.py`` and
+ edit the following dictionaries:
+
+ - ``devices_to_classes`` --> add the following entry:
+ ``"<type>" : "<Type>"``
+ if you followed these instructions carefully the name of the class
+ implementing the function ``<type>`` should be ``<Type>.java``
+ under the package ``mcnet.netobjs``.
+ - ``devices_to_configuration_methods`` --> add the following entry:
+ ``"<type>" : "configurationMethod"``
+ if ``<type>`` is a middlebox it should have a configuration method
+ contained in the implementation ``<Type>.java`` under the package
+ ``mcnet.netobjs``.
+ - ``devices_initialization``: add the following entry:
+ ``"<type>" : ["param1", "param2"]``
+ if ``<type>`` requires any parameter when it gets instanciated
+ please enter them in the form of a list. Make sure that these
+ parameters refer to existing keys contained in the configuration
+ schema file (see step 3). For instance the type ``webclient``
+ requires the name of a webserver it wants to communicate with.
+ This parameter is passed in the configuration of a weblient by
+ setting a property ``webserver`` to the name of the desired
+ webserver. The value of this property gets extracted and used by
+ the test generator automatically.
+ - ``convert_configuration_property_to_ip`` --> add the following
+ entry: ``"<type>" : ["key", "value"]``
+ Note that both ``key`` and ``value`` are optional and it is
+ critical to set them only if needed. Since the Z3 provider used
+ for testing works with IP addresses in this dictionary you have to
+ indicate whether it is needed an automatic convertion from names
+ to IP addresses:
+ - in case the keyword ``key`` is used every key of the JSON
+ configuration parsed will be prepended with the string ``ip_``;
+ - in case the keyword ``value`` is used every value of the JSON
+ configuration parsed will be prepended with the string ``ip_``;
+ - in case the list does not contain neither ``key`` nor ``value``
+ the original configuration won't be touched.
+
+- open the file
+ ``/verify/service/src/tests/j-verigraph-generator/test_class_generator.py``
+ and under the "switch" case in the form of a series of ifs used to
+ configure middle-boxes that starts at line #239 add a branch like the
+ following with the logic to generate the Java code for -->
+ ``elif nodes_types[i] == "<type>":``
+ You can take inspiration from the other branches to see how to
+ serialize Java code. Note that this addition to the "switch"
+ statement is not needed if ``<type>`` is not a middlebox or it does
+ not need to be configured.
+
+#. Restart the web service.

+CODE\_GENERATOR Java serializer and formatter
+
+UTILITY Contains utility methods used by other modules
+
+JSON\_GENERATOR Interactive module to generate the configuration files
+(default names are "chains.json" and "config.json") "chains.json"
+describes all the chains of nodes belonging to a certain scenario
+
+TEST\_CLASS\_GENERATOR Generates one or multiple test scenarios given
+the two configuration files above (default names are "chains.json" and
+"config.json") All the test scenarios have to be placed in the examples
+folder (i. e. under "j-verigraph/service/src/tests/examples"). Here is
+the script help:
+
+test\_class\_generator.py -c -f -o
+
+Supposing the module gets executed from the project root directory (i.e.
+"j-verigraph"), a sample command is the following:
+
+service/src/tests/j-verigraph-generator/test\_class\_generator.py -c
+"service/src/tests/j-verigraph-generator/examples/budapest/chains.json"
+-f
+"service/src/tests/j-verigraph-generator/examples/budapest/config.json"
+-o "service/src/tests/examples/Scenario"
+
+Keep in mind that in the previous command "Scenario" represents a prefix
+which will be followed by an underscore and an incremental number
+starting from 1, which represents the n-th scenario starting from the
+previously mentioned "chains.json" file (this file can indeed contain
+multiple chains).
+
+TEST\_GENERATOR Generates a file which performs the verification test
+through Z3 (theorem prover from Microsoft Research) given a certain
+scenario generated with the above snippet. All the test modules have to
+be placed under the "tests" directory (i.e. under
+"j-verigraph/service/src/tests"). Here is the module help:
+
+test\_generator.py -i -o -s -d
+
+Supposing the module gets executed from the project root directory (i.e.
+"j-verigraph") a sample command given the previously generated scenario
+is the following:
+
+service/src/tests/j-verigraph-generator/test\_generator.py -i
+service/src/tests/examples/Scenario\_1.java -o
+service/src/tests/Test.java -s user1 -d webserver
+
+The aforementioned "Test.java" file can be compiled and executed
+normally. Its output will be either "SAT" or "UNSAT". For possible
+statistics the test is repeated 10 times and the average execution time
+in seconds is printed to the console.

+gRPC Project
+============
+
+This project contains the interfaces for a web service based on gRPC.
+
+How to install:
+---------------
+
+For gRPC interface, add to your ``pom.xml`` (in the project this part is
+already present):
+
+::
+
+ <dependency>
+ <groupId>io.grpc</groupId>
+ <artifactId>grpc-netty</artifactId>
+ <version>${grpc.version}</version>
+ </dependency>
+ <dependency>
+ <groupId>io.grpc</groupId>
+ <artifactId>grpc-protobuf</artifactId>
+ <version>${grpc.version}</version>
+ </dependency>
+ <dependency>
+ <groupId>io.grpc</groupId>
+ <artifactId>grpc-stub</artifactId>
+ <version>${grpc.version}</version>
+ </dependency>
+
+For protobuf-based codegen integrated with the Maven build system, you
+can use protobuf-maven-plugin :
+
+::
+
+ <build>
+ <extensions>
+ <extension>
+ <groupId>kr.motd.maven</groupId>
+ <artifactId>os-maven-plugin</artifactId>
+ <version>1.4.1.Final</version>
+ </extension>
+ </extensions>
+ <plugins>
+ <plugin>
+ <groupId>org.xolstice.maven.plugins</groupId>
+ <artifactId>protobuf-maven-plugin</artifactId>
+ <version>0.5.0</version>
+ <configuration>
+ <protocArtifact>com.google.protobuf:protoc:3.1.0:exe:${os.detected.classifier}</protocArtifact>
+ <pluginId>grpc-java</pluginId>
+ <pluginArtifact>io.grpc:protoc-gen-grpc-java:${grpc.version}:exe:${os.detected.classifier}</pluginArtifact>
+ </configuration>
+ <executions>
+ <execution>
+ <goals>
+ <goal>compile</goal>
+ <goal>compile-custom</goal>
+ </goals>
+ </execution>
+ </executions>
+ </plugin>
+ </plugins>
+ </build>
+
+| In order to run the gRPC server and the junit test, you need to download the Manven Ant Task library
+ from `here <https://mvnrepository.com/artifact/org.apache.maven/maven-ant-tasks/2.1.3>`__
+ and copy into ``[verigraph]/lib/``
+
+| Due to the fact that the project is intended for Eclipse, you need to
+ install an additional Eclipse plugin because
+ `m2e <https://www.eclipse.org/m2e/>`__ does not evaluate the extension
+ specified in a ``pom.xml``. `Download
+ ``os-maven-plugin-1.5.0.Final.jar`` <http://repo1.maven.org/maven2/kr/motd/maven/os-maven-plugin/1.5.0.Final/os-maven-plugin-1.5.0.Final.jar>`__
+ and put it into the ``<ECLIPSE_HOME>/plugins`` directory.
+| (As you might have noticed, ``os-maven-plugin`` is a Maven extension,
+ a Maven plugin, and an Eclipse plugin.)
+
+If you are using IntelliJ IDEA, you should not have any problem.
+
+If you are using other IDEs such as NetBeans, you need to set the system
+properties ``os-maven-plugin`` sets manually when your IDE is launched.
+You usually use JVM's ``-D`` flags like the following:
+
+ | -Dos.detected.name=linux
+ | -Dos.detected.arch=x86\_64
+ | -Dos.detected.classifier=linux-x86\_64
+
+Included files:
+---------------
+
+Here you can find a brief description about useful files for the gRPC
+interface:
+
+**src/main/java:**
+
+- *it.polito.grpc:*
+
+This package includes 2 classes that represent the client and server.
+
+ **Client.java:**
+
+ | Client of gRPC application. It implements all possible methods
+ necessary for communicate with server.
+ | It prints out the received response.
+ | Moreover it provides some static methods that are used for
+ creating the instances of requests.
+
+ **Service.java:**
+
+ | Server of gRPC application. It implements all possible methods
+ necessary for communicate with client.
+ | It saves the received request on log.
+ | This server could be accessed by multiple clients, because
+ synchronizes concurrent accesses.
+ | Each method that is possible to call is has the equivalent
+ operation in REST-interface.
+
+ **GrpcUtils.java:**
+
+ | This class provides some static methods that are used by
+ ``Service.java`` in order to translate a request into a class that
+ is accepted by Verigraph.
+ | Other methods are used to translate the class of Verigraph in the
+ proper gRPC response.
+ | These functionalities are exploited by test classes.
+ | Furthermore this set of methods is public, so in your application
+ you could call them, even if this should not be useful because
+ ``Client.java`` provides other high-level functions.
+
+- *it.polito.grpc.test:*
+
+ This package includes classes for testing the gRPC application.
+
+ **GrpcServerTest.java:**
+
+ | For each possible method we test if works correctly.
+ | We create a fake client (so this test doesn't use the method that
+ are present in client class) and test if it receives the expected
+ response.
+ | In a nutshell, it tests the methods of Client in case of a fake
+ server.
+ | Please notice that the test prints some errors but this is
+ intentional, because the program tests also error case.
+ | Indeed, not all methods are tested, because we have another class
+ (ReachabilityTest.java) that is specialized for testing the
+ verification method.
+
+ **GrpcTest.java:**
+
+ | This set of tests is intended to control the most common use
+ cases, in particular all methods that are callable in Client and
+ Service class, apart from verifyPolicy for the same reason as
+ before.
+ | It tries also to raise an exception and verify if the behavior is
+ as expected.
+
+ **MultiThreadTest.java:**
+
+ | This test creates multiple clients that connect to the server and
+ verify is the result is correct. These methods test the
+ synchronization on
+ | server-side.
+
+ **ReachabilityTest.java:**
+
+ | This file tests the verification method, it exploits the test case
+ already present in the project and consequently has the certainty
+ of testing not so simple case. In particular it reads the file in
+ "src/main/webapp/json" and use this as starting point.
+ | Some exceptions are thrown in order to verify if they are handled
+ in a correct way.
+
+**src/main/proto:**
+
+ **verigraph.proto:**
+
+ | File containing the description of the service. This includes the
+ definition of all classes used in the application.
+ | Moreover contains the definition of the methods that is possible
+ to call.
+ | Each possible method called by REST API is mapped on a proper gRPC
+ method.
+ | In case of error a message containing the reason is returned to
+ the client.
+ | More details are available in the section about Proto Buffer.
+
+**taget/generated-sources/protobuf/java:**
+
+- *io.grpc.verigraph:*
+
+ This package includes all classes generated from verigraph.proto by
+ means of protoc. For each object you can find 2 classes :
+
+ **{NameObject}Grpc.java**
+
+ **{NameObject}GrpcOrBuilder.java**
+
+ The first is the real implementation, the second is the
+ interface.
+
+**taget/generated-sources/protobuf/grpc-java:**
+
+- *io.grpc.verigraph:*
+
+ This package includes a single class generated from verigraph.proto
+ by means of protoc.
+
+ **VerigraphGrpc.java:**
+
+ This is useful in order to create the stubs that are necessary to
+ communicate both for client and server.
+
+**lib:**
+
+This folder includes a jar used for compiling the project with Ant.
+
+ \*\*maven-ant-tasks-2.1.3.\ jar:**
+
+ This file is used by build.xml in order to include the maven
+ dependencies.
+
+**pom.xml:**
+
+| Modified in order to add all necessary dependencies. It contains also
+ the build tag used for create the generated-sources folders.
+| This part is added according to documentation of gRPC for java as
+ explained above in How To Install section.
+| For further clarification go to `this
+ link <https://github.com/grpc/grpc-java/blob/master/README.md>`__.
+
+**build.xml:**
+
+This ant file permit to run and compile the program in a simple way, it
+exploits the maven-ant-tasks-2.1.3.jar already present in project.
+
+It contains 3 fundamental tasks for gRPC interface:
+
+- **build:** compile the program
+
+- **run:** run both client and server
+
+- **run-client :** run only client
+
+- **run-server :** run only server
+
+- **run-test :** launch all tests that are present in the package,
+ prints out the partial results and global result.
+
+Note that the execution of these tests may take up to 1-2 minutes when
+successful, according to your computer architecture.
+
+More Information About Proto Buffer:
+------------------------------------
+
+Further clarification about verigraph.proto:
+
+- A ``simple RPC`` where the client sends a request to the server using
+ the stub and waits for a response to come back, just like a normal
+ function call.
+
+ .. code:: xml
+
+ // Obtains a graph
+ rpc GetGraph (RequestID) returns (GraphGrpc) {}
+
+In this case we send a request that contains the id of the graph and the
+response is a Graph.
+
+- A ``server-side streaming RPC`` where the client sends a request to
+ the server and gets a stream to read a sequence of messages back. The
+ client reads from the returned stream until there are no more
+ messages. As you can see in our example, you specify a server-side
+ streaming method by placing the stream keyword before the response
+ type.
+
+ .. code:: xml
+
+
+ // Obtains a list of Nodes
+ rpc GetNodes (RequestID) returns (stream NodeGrpc) {}
+
+In this case we send a request that contains the id of the graph and the
+response is a list of Nodes that are inside graph.
+
+Further possibilities are available but in this project are not
+expolied. If you are curious see
+`here <http://www.grpc.io/docs/tutorials/basic/java.html#defining-the-service>`__.
+
+Our ``.proto`` file also contains protocol buffer message type
+definitions for all the request and response types used in our service
+methods - for example, here\92s the ``RequestID`` message type:
+
+.. code:: xml
+
+ message RequestID {
+ int64 idGraph = 1;
+ int64 idNode = 2;
+ int64 idNeighbour = 3;
+ }
+
+The " = 1", " = 2" markers on each element identify the unique "tag"
+that field uses in the binary encoding. Tag numbers 1-15 require one
+less byte to encode than higher numbers, so as an optimization you can
+decide to use those tags for the commonly used or repeated elements,
+leaving tags 16 and higher for less-commonly used optional elements.
+Each element in a repeated field requires re-encoding the tag number, so
+repeated fields are particularly good candidates for this optimization.
+
+Protocol buffers are the flexible, efficient, automated solution to
+solve exactly the problem of serialization. With protocol buffers, you
+write a .proto description of the data structure you wish to store. From
+that, the protocol buffer compiler creates a class that implements
+automatic encoding and parsing of the protocol buffer data with an
+efficient binary format. The generated class provides getters and
+setters for the fields that make up a protocol buffer and takes care of
+the details of reading and writing the protocol buffer as a unit.
+Importantly, the protocol buffer format supports the idea of extending
+the format over time in such a way that the code can still read data
+encoded with the old format.
+
+::
+
+ syntax = "proto3";
+
+ package verigraph;
+
+ option java_multiple_files = true;
+ option java_package = "io.grpc.verigraph";
+ option java_outer_classname = "VerigraphProto";
+ ```
+
+This .proto file works for protobuf 3, that is slightly different from
+the version 2, so be careful if you have code already installed.
+
+The .proto file starts with a package declaration, which helps to
+prevent naming conflicts between different projects. In Java, the
+package name is used as the ``Java package`` unless you have explicitly
+specified a java\_package, as we have here. Even if you do provide a
+``java_package``, you should still define a normal ``package`` as well
+to avoid name collisions in the Protocol Buffers name space as well as
+in non-Java languages.
+
+| After the package declaration, you can see two options that are
+ Java-specific: ``java_package`` and ``java_outer_classname``.
+ ``java_package`` specifies in what Java package name your generated
+ classes should live. If you don't specify this explicitly, it simply
+ matches the package name given by the package declaration, but these
+ names usually aren't appropriate Java package names (since they
+ usually don't start with a domain name). The ``java_outer_classname``
+ option defines the class name which should contain all of the classes
+ in this file. If you don't give a ``java_outer_classname explicitly``,
+ it will be generated by converting the file name to camel case. For
+ example, "my\_proto.proto" would, by default, use "MyProto" as the
+ outer class name.
+| In this case this file is not generated, because
+ ``java_multiple_files`` option is true, so for each message we
+ generate a different class.
+
+For further clarifications see
+`here <https://developers.google.com/protocol-buffers/docs/javatutorial>`__
+
+Notes
+-----
+
+For gRPC interface you need that neo4jmanager service is already
+deployed, so if this is not the case, please follow the instructions at
+this
+`link <https://github.com/netgroup-polito/verigraph/blob/a3c008a971a8b16552a20bf2484ebf8717735dd6/README.md>`__.
+
+In this version there are some modified files compared to the original
+`Verigraph project <https://github.com/netgroup-polito/verigraph>`__
+
+**it.polito.escape.verify.service.NodeService:**
+
+At line 213 we modified the path, because this service is intended to
+run not only in container, as Tomcat, so we added other possibility that
+files is placed in src/main/webapp/json/ folder.
+
+**it.polito.escape.verify.service.VerificationService:**
+
+In the original case it searches for python files in "webapps" folder,
+that is present if the service is deployed in a container, but absent
+otherwise. So we added another string that will be used in the case the
+service doesn't run in Tomcat.
+
+**it.polito.escape.verify.databese.DatabaseClass:**
+
+Like before we added the possibility that files are not in "webapps"
+folder, so is modified in order to run in any environment. Modification
+in method loadDataBase() and persistDatabase().
+
+| Pay attention that Python is needed for the project. If it is not
+ already present on your computer, please `download
+ it <https://www.python.org/download/releases/2.7.3/>`__.
+| It works fine with Python 2.7.3, or in general Python 2.
+
+| If you have downloaded a Python version for 64-bit architecture please
+ copy the files in "service/z3\_64" and paste in "service/build" and
+ substitute them,
+| because this project works with Python for 32-bit architecture.
+
+Python and Z3 must support the same architetcure.
+
+Moreover you need the following dependencies installed on your python
+distribution:
+
+- "requests" python package ->
+http://docs.python-requests.org/en/master/
+
+- "jsonschema" python package -> https://pypi.python.org/pypi/jsonschema
+
+| HINT - to install a package you can raise the following command (Bash
+ on Linux or DOS shell on Windows): python -m pip install jsonschema
+ python -m pip install requests
+| Pay attention that it is possible that you have to modify the PATH
+ environment variable because is necessary to address the python
+ folder, used for verification phase.
+
+Remember to read the
+`README.rtf <https://gitlab.com/serena.spinoso/DP2.2017.SpecialProject2.gRPC/tree/master>`__
+and to follow the instructions in order to deploy the Verigraph service.
+
+| In the latest version of Maven there is the possibility that the
+ downloaded files are incompatible with Java Version of the project
+ (1.8).
+| In this case you have to modify the file ``hk2-parent-2.4.0-b31.pom``
+ under your local Maven repository (e.g.
+ 'C:\\Users\\Standard.m2\\repository')
+| and in the path ``\org\glassfish\hk2\hk2-parent\2.4.0-b31`` find the
+ file and modify at line 1098 (in section ``profile``) the ``jdk``
+ version to ``[1.8,)`` .
+
+| Admittedly, the version that is supported by the downloaded files from
+ Maven Dependencies is incompatible with jdk of the project.
+| So modify the file ``gson-2.3.pom`` in Maven repository, under
+ ``com\google\code\gson\gson\2.3`` directory, in particular line 91,
+ from ``[1.8,`` to ``[1.8,)``.
+
+This project was also tested on Linux Ubuntu 15.10.

+In order to run the automatic testing script test.py, you need the
+following dependencies installed on your python distribution:
+
+- "requests" python package ->
+ http://docs.python-requests.org/en/master/
+- "jsonschema" python package ->
+ https://pypi.python.org/pypi/jsonschema
+
+IMPORTANT - If you have multiple versions of Python installed on your
+machine, check carefully that the version you are actually using when
+running the script, has the required packages installed. Requested
+version is Python 3+
+
+| HINT - to install a package you can raise the following command (Bash
+ on Linux or DOS shell on Windows):
+| python -m pip install jsonschema
+| python -m pip install requests
+
+Tested on PYTHON 3.4.3
+
+To add a new test, just put a new .json file inside the testcases
+folder. The corresponding JSON schema is in the testcase\_schema.json
+file and some examples are already available. Each json file should
+specify:
+
+- id, an integer for the testcase;
+- name, the name for the testcase;
+- description, an optional description;
+- policy\_url\_parameters, the parameters to be appended after the
+ verification URL (including the '?' character);
+- result, the expected verification result;
+- graph, the graph to be tested (the same object that you usually POST
+ to VeriGraph to create a new graph).
+ The test.py script will test each .json file contained into the
+ testcases folder and will provide a complete output.
