swh.osv.luigi.vuln2commit module

Luigi tasks for building the vulnerability-to-commit mapping

class swh.osv.luigi.vuln2commit.Vuln2CommitParquet(*args, **kwargs)

Bases: Task

Creates a Parquet dataset that maps each vulnerability to the commits that fix it.

local_graph_path

Parameter whose value is a path.

In the task definition, use

class MyTask(luigi.Task):
    existing_file_path = luigi.PathParameter(exists=True)
    new_file_path = luigi.PathParameter()

    def run(self):
        # Get data from existing file
        with self.existing_file_path.open("r", encoding="utf-8") as f:
            data = f.read()

        # Output message in new file
        self.new_file_path.parent.mkdir(parents=True, exist_ok=True)
        with self.new_file_path.open("w", encoding="utf-8") as f:
            f.write("hello from a PathParameter => ")
            f.write(data)

At the command line, use

$ luigi --module my_tasks MyTask --existing-file-path <path> --new-file-path <path>

graph_name

Parameter whose value is a str.

vulnerabilities_dir

Parameter whose value is a path.

In the task definition, use

class MyTask(luigi.Task):
    existing_file_path = luigi.PathParameter(exists=True)
    new_file_path = luigi.PathParameter()

    def run(self):
        # Get data from existing file
        with self.existing_file_path.open("r", encoding="utf-8") as f:
            data = f.read()

        # Output message in new file
        self.new_file_path.parent.mkdir(parents=True, exist_ok=True)
        with self.new_file_path.open("w", encoding="utf-8") as f:
            f.write("hello from a PathParameter => ")
            f.write(data)

At the command line, use

$ luigi --module my_tasks MyTask --existing-file-path <path> --new-file-path <path>

include_vcs_matches

A Parameter whose value is a bool. This parameter has an implicit default value of False. For the command line interface this means that the value is False unless you add "--the-bool-parameter" to your command without giving a parameter value. This is considered implicit parsing (the default). However, in some situations one might want to give the explicit bool value ("--the-bool-parameter true|false"), e.g. when you configure the default value to be True. This is called explicit parsing. When omitting the parameter value, it is still considered True but to avoid ambiguities during argument parsing, make sure to always place bool parameters behind the task family on the command line when using explicit parsing.

You can toggle between the two parsing modes on a per-parameter base via

class MyTask(luigi.Task):
    implicit_bool = luigi.BoolParameter(parsing=luigi.BoolParameter.IMPLICIT_PARSING)
    explicit_bool = luigi.BoolParameter(parsing=luigi.BoolParameter.EXPLICIT_PARSING)

or globally by

luigi.BoolParameter.parsing = luigi.BoolParameter.EXPLICIT_PARSING

for all bool parameters instantiated after this line.
