A central repository for python utility functions and everything that deals with the graphsense backend. Its CLI interface can be used to control important graphsense maintainance tasks.

Use

As a library

Access the graphsense cassandra db. This requires a graphsense config (see Modules/Config)

from graphsenselib.db import DbFactory

env, currency = "test", "btc"

with DbFactory().from_config(env, currency) as db:
    print(db.transformed.get_highest_block())

Alternatively, the database can also be accessed without relying on the graphsense config file.

from graphsenselib.db import DbFactory

with DbFactory().from_name(
        raw_keyspace_name="eth_raw",
        transformed_keyspace_name="eth_transformed",
        schema_type="account",
        cassandra_nodes = ["test.cassandra1", "test.cassandra2"]
    ) as db:
    print(db.transformed.get_highest_block())

From the commandline.

Graphsenslib exposes a commandline interface - graphsence-cli.

Install

To install the package from the python package index run.

  > pip install graphsense-lib

If you want to install it from source run

  > make install

or

  > pip install .

Development

Caution: python 3.11 is currently not supported. Please use python3.10.

it is advised to use a virtual environment (venv) for development. Run the following command to initialize one

    > python3 -m venv .venv

and activate it (in bash) using

    > source .venv/bin/activate

For more information refer to (venv). Run

    > make dev

to initialize the dev environment. If you want to install graphsenselib in development mode run

    > make install-dev

Before committing anything to the repository please format, lint and test your code in that order. Fix all linter warnings and make sure all test are passing before a commit.

Use the following commands for that:

    > make format
    > make lint
    > make test

or equivalently run

    > make pre-commit

Some slow tests are excluded when running make test. Occasionally, one should run

    > make test-all

to run the entire test-suite.

Linting and formatting should be automatically executed on every git commit, using pre-commit.

To create the documentation please run:

    > make docs

Creating the docs need python dev dependencies to build see (Stackoverflow)

Tagging a release

To tag a new release please update the changelog first. Afterwards, update the Version numbers RELEASESEM and RELEASE in the main Makefile.

To apply the tags run

    > make tag-version

Open SSL - Errors running test suites

Some components used by graphsense-lib use OpenSSL, to provide certain hash functions. Since OpenSSL 3.0 some hash functions needed are not available anymore by default (e.g. ripemd160). This leads to errors while running the test suite. To avoid these errors, enable legacy providers in the OpenSSL config. An example of the necessary changes can be found in the "fix openssl legacy mode" step in .github/workflows/run_tests.yaml
