SearchSECO Controller

This is the Controller module used by the SearchSECO project. It is responsible for mediating communication between the other modules, and talking to the user. A reference documentation can be found here.

Running locally

If you want to run the controller connected to the official database, The easiest way is to use the Docker hub image. To do this you need to have Docker installed. After this you can use the following command if you just want to run the start command:

docker run --name controller-container -e "github_token=<github_token>" -e "worker_name=<worker_name>" searchseco/controller

If you want to run a custom command you can use the following command:

docker run --name controller-container --entrypoint="./controller/build/searchseco" -e "github_token=<github_token>" -e "worker_name=<worker_name>" searchseco/controller <command>

In these commands you should replace <github_token> with your github token and <worker_name> with a name for you node to contact to the database with.

Developing

For developing there are a couple of ways to run the local code as described here. A more elaborate explanation of the architecture can be found in the full documentation.

Cloning

After cloning the repository, make sure to initialize and update the submodules by calling

> git submodule init 
> git submodule update

Dependencies

Windows 10+, Ubuntu 18.04+. Might work on older Windows versions or other UNIX systems but has not been tested.
Boost 1.76.0
- UNIX
  - Install libboost-all-dev
- Windows
  - Save the unzipped directory at the path C:\Program Files\Boost\boost_1_76_0.
  - In an adminstrative command prompt, run
```
> bootstrap.bat
> b2.exe
```
SearchSECOCrawler
SearchSECOSpider
SearchSECOParser

Configuration

There are a couple of configurations that can/need to be done. Firstly the SearchSECOController/.env file should contain the ip adresses and ports of the database apis to connect to. Secondly the SearchSECOController/cfg/config.txt file contains some more configurations. The worker name field should contain a name for your worker, which will be sent to the database api. Also the github token should have a correct github token. For info on creating this token click here. The token needs no permissions (see step 7 of guide) so it will not be able to interact with your personal GitHub account in any way. Without providing a token, the program will not be able to use the SearchSECOCrawler (making it impossible to crawl repositories or upload projects). There are also some optional configurations in this file, like the vorbosity of the output and the amount of CPU cores to use.

Building

Docker

You can use the code to build a Docker image. Make sure Docker is installed. In the root of the project run

docker build -t controller-image .

This will build the image for the container. After this you can use the following command to run the container:

docker run --name=controller-container --network=host -d --restart=always controller-image

This will start the container in detached mode and it will restart automatically. This is perfect for when you just want to start the worker node. If you want to see the console and be able to issue the stop command you should use the following command:

docker run --name=controller-container --network=host -i controller-image

By default the build command will build an image that will run the start command. In order to use other commands with Docker you can remove the , "start" from the last line of the dockerfile and then use the same build command to build the image and then the interactive run command to run the program. It will listen for a command input, so any command can be put in.

CMake

Make sure CMake is installed.

In the root of the project, run

> mkdir build && cd build
> cmake ../SearchSECOController
> cmake --build .

Verify the install was successful by running

> ./searchseco -v   (UNIX)
> searchseco -v     (Windows)

Visual Studio

Open the solution and simply build the project. When the terminal is started up, you need to only pass the command + flags, without the preceding searchseco.

Usage

After building the program, it can be called using the following syntax:

searchseco command mandatory_argument [--optional_flag flag_argument]

To see the full list of commands and their functionality see the official user manual or use the -h flag.
