Test task for ALT

This program is a dynamic library and a command line interface that uses this library. It compares two branches from altrepo and outputs the result in JSON format to a file

{
  "arch":{
    "only_in_first":{
      "length": 0,
      "packages": []
    },
    "only_in_second":{
      "length": 0,
      "packages": []
    },
    "in_first_release_greater":{
      "length": 0,
      "packages": []
    }
  },
  ...
}

"only_in_first" - all packages that are in the 1st but not in the 2nd

"only_in_second" - all packages that are in the 2nd but they are not in the 1st

"in_first_release_greater" - all packages whose version-release is greater in the 1st than in the 2nd

---

"length" - number of packages

"array" - array of packages

---

packages json format

{
  "name": "string",
  "epoch": 0,
  "version": "string",
  "release": "string",
  "arch": "string",
  "disttag": "string",
  "buildtime": 0,
  "source": "string"
}

Build Linux ALT workstation 10.1

0. Install CMake, g++, git and clone repository

sudo apt-get update

sudo apt-get install gcc-g++

sudo apt-get install cmake

sudo apt-get install git

sudo git clone https://github.com/rautyrauty/test-task-ALT

1. Install Boost C++ Libraries and OpenSSL

sudo apt-get install boost-devel

sudo apt-get install boost-asio-devel

sudo apt-get install libssl-devel

2. Build

cd test-task-ALT
sudo cmake .
sudo cmake --build ./

If OpenSSL or Boost is installed in a non-standard location you can set options:

sudo cmake --build ./ -DOPENSSL_ROOT_DIR=some_dir -DBOOST_ROOT=some_dir

to get the paths to boost and openssl, use the "whereis" command:

whereis boost

whereis openssl

Build Linux Ubuntu 22.04

0. Install CMake

sudo apt-get update
sudo apt-get install cmake

1. Install Boost C++ Libraries and OpenSSL

sudo apt-get install libboost-all-dev
sudo apt-get install libssl-dev

2. Build

cd [root-directory-of-project]
sudo cmake .
sudo cmake --build ./

If OpenSSL or Boost is installed in a non-standard location you can set options:

sudo cmake --build ./ -DOPENSSL_ROOT_DIR=some_dir -DBOOST_ROOT=some_dir

to get the paths to boost and openssl, use the "whereis" command:

whereis boost
whereis openssl

Usage

1. Enter the name of the two branches
2. Get the file
