KCIDB = Linux Kernel CI reporting - I/O data library

kcidb-io

kcidb-io is a Python 3 library for validating and manipulating Linux Kernel CI reports in JSON format. This library is used by kcidb - a package for maintaining a service storing and serving that data.

Installation

kcidb-io requires Python v3.10 or later.

To install the latest version from PyPI:

pip3 install kcidb-io

To install from the git repository:

pip3 install git+https://github.com/kernelci/kcidb-io.git

To install from a local directory:

pip3 install .

Using

Here's an example creating an empty report and then validating it:

# Import the kcidb-io package
import kcidb_io
# Create an empty report using the latest schema version
json = kcidb_io.new()
# Validate the report
kcidb_io.schema.validate(json)

Exporting the JSON schema

The current schema is available as a JSON Schema dictionary on the version class. The latest schema is exposed as kcidb_io.schema.LATEST.

Export the latest schema to a file:

python3 - <<'PY'
import json
from kcidb_io import schema

v = schema.LATEST
with open(f"kcidb-io.schema.v{v.major}.{v.minor}.json", "w") as f:
    json.dump(v.json, f, indent=2, sort_keys=True)
PY

Compatibility notes

The schema is validated in this library using JSON Schema Draft-07. The exported schema JSON does not include a $schema field; if a validator requires one, add:

{
  "$schema": "http://json-schema.org/draft-07/schema#"
}

The schema uses $defs and the uri string format. If your validator supports format checking, enable it to validate uri values.

Hacking

If you want to hack on the source code, install the package in the editable mode with the -e/--editable option, and with "dev" extra included. E.g.:

pip3 install --user --editable '.[dev]'

The latter installs the kcidb-io package using the modules from the source directory, and changes to them will be reflected immediately without the need to reinstall. It also installs extra development tools, such as flake8 and pylint.
