KCIDB

Kcidb is a package for submitting and querying Linux Kernel CI reports, and for maintaining the service behind that.

See the collected results on our dashboard. Write to [email protected] if you want to start submitting results from your CI system, or if you want to receive automatic notifications of arriving results.

Installation

Kcidb requires Python v3.6 or later.

To install the package for the current user, run this command:

pip3 install --user <SOURCE>

Where <SOURCE> is the location of the package source, e.g. a git repo:

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

or a directory path:

pip3 install --user .

In any case, make sure your PATH includes the ~/.local/bin directory, e.g. with:

export PATH="$PATH":~/.local/bin

Before you execute any of the tools make sure you have the path to your Google Cloud credentials stored in the GOOGLE_APPLICATION_CREDENTIALS variable. E.g.:

export GOOGLE_APPLICATION_CREDENTIALS=~/.credentials.json

User guide

Submitting and querying

To submit records use kcidb-submit, to query records - kcidb-query. Both use the same JSON schema on standard input and output respectively, which can be displayed by kcidb-schema. You can validate the data without submitting it using the kcidb-validate tool.

See Submission HOWTO for details.

API

You can use the kcidb module to do everything the command-line tools do.

First, make sure you have the GOOGLE_APPLICATION_CREDENTIALS environment variable set and pointing at your Google Cloud credentials file. Then you can create the client with kcidb.Client(...) and call its submit(...) and query(...) methods.

You can find the I/O schema in kcidb.io.schema.LATEST.json and use kcidb.io.schema.validate() to validate your I/O data.

See the source code for additional documentation.

Administrator guide

See ADMINISTRATOR_GUIDE.md.

Developer guide

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 kcidb executables which use 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.

Releasing

Before releasing make sure the README.md and SUBMISSION_HOWTO.md are up to date.

To make a release tag the release commit with v<NUMBER>, where <NUMBER> is the next release number, e.g. v3. The very next commit after the tag should update the version number in setup.py to be the next one. I.e. continuing the above example, it should be 4.
