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.

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, heres 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.
