compare_branches

CLI utility for getting package descriptions using ALTRepo API, and further comparison.

Requirements

  • Qt 5
  • librpm
  • C++17

Building

Change into source directory and say:

qmake -r
make

The executable and shared library will be placed in the build subdirectory.

Using

compare_branches <branch1> <branch2>

branch1 and branch2 are the branch names of the ALT Linux distribution. The command makes a request using method /export/branch_binary_packages/{branch} As a result of execution, the command sends JSON to the standard output.

Execution result example:

{
    "query": [
        {
            "arch": "aarch64",
            "greater1": [
                {
                    "arch": "aarch64",
                    "buildtime": 1657802745,
                    "disttag": "p10+303432.100.3.1",
                    "epoch": 1,
                    "name": "0ad-debuginfo",
                    "release": "alt0_0_rc1.p10",
                    "source": "0ad",
                    "version": "0.1.26"
                },
                {
                    "arch": "aarch64",
                    "buildtime": 1633419531,
                    "disttag": "p10+284894.100.5.1",
                    "epoch": 0,
                    "name": "389-ds-base-libs",
                    "release": "alt1",
                    "source": "389-ds-base",
                    "version": "1.4.4.25"
                },

                ... other package descriptions

            ],
            "only1": [

                package descriptions

            ],
            "only2": [

                package descriptions

            ]
        },
        {
            "arch": "armh",
            "greater1": [ ... ],
            "only1": [ ... ],
            "only2": [ ... ]
        },

        ... other architectures

    ]
}

The output is divided by architecture, within each architecture there are 3 sections:

  • greater1 - All elements whose version in the branch1 is greater than in the branch2
  • only1 - All elements that are in the branch1, but not in the branch2
  • only2 - All elements that are in the branch2, but not in the branch1
