usage: reprotest --help [<virtual_server_name>]
       reprotest [options] [-c <build-command>] <source_root> [<artifact_pattern>]
                 [-- <virtual_server_args> [<virtual_server_args> ...]]
       reprotest [options] [-s <source_root>] <build_command> [<artifact_pattern>]
                 [-- <virtual_server_args> [<virtual_server_args> ...]]

Build packages and check them for reproducibility.

positional arguments:
  source_root|build_command
                        The first argument is treated either as a source_root
                        (see the -s option) or as a build-command (see the -c
                        option) depending on what it looks like. Most of the
                        time, this should "just work"; but specifically: if
                        neither -c nor -s are given, then: if this exists as a
                        file or directory and is not "auto", then this is
                        treated as a source_root, else as a build_command.
                        Otherwise, if one of -c or -s is given, then this is
                        treated as the other one. If both are given, then this
                        is a syntax error and we exit code 2.
  artifact_pattern      Build artifact to test for reproducibility. May be a
                        shell pattern such as "*.deb *.changes".
  virtual_server_args   Arguments to pass to the virtual_server, the first
                        argument being the name of the server. If this itself
                        contains options (of the form -xxx or --xxx), or if
                        any of the previous arguments are omitted, you should
                        put a "--" between these arguments and reprotest's own
                        options. Default: "null", to run directly in /tmp.
                        Choices: chroot, lxc, lxd, null, qemu, schroot, ssh

optional arguments:
  --help [VIRTUAL_SERVER_NAME]
                        Show this help message and exit. When given an
                        argument, show instead the help message for that
                        virtual server and exit.
  -f CONFIG_FILE, --config-file CONFIG_FILE
                        File to load configuration from. (Default: None)

basic options:
  --verbosity VERBOSITY
                        An integer. Control which messages are displayed.
  -v, --verbose         Like --verbosity, but given multiple times without
                        arguments.
  --host-distro HOST_DISTRO
                        The distribution that will run the tests (Default:
                        None)
  -s PATH, --source-root PATH
                        Root of the source tree, that is copied to the virtual
                        server and made available during the build. If a file
                        is given here, then its parent directory is used
                        instead. Default: "." (current working directory).
  --source-pattern PATTERNS
                        Shell glob pattern to restrict the files in
                        <source_root> that are made available during the
                        build. Default: empty, i.e. copy the whole
                        <source_root> directory with no restrictions.
  -c COMMANDS, --build-command COMMANDS
                        Build command to execute. If this is "auto" then
                        reprotest will guess how to build the given
                        source_root, in which case various other options may
                        be automatically set-if-unset. Default: auto
  --store-dir DIRECTORY
                        Save the artifacts in this directory, which must be
                        empty or non-existent. Otherwise, the artifacts will
                        be deleted and you only see their hashes (if
                        reproducible) or the diff output (if not).
  --variations VARIATIONS
                        Build variations to test as a comma-separated list of
                        variation names. Default is "+all", equivalent to
                        "+environment, +build_path, +kernel, +aslr, +num_cpus,
                        +time, +user_group, +fileordering, +domain_host,
                        +home, +locales, +exec_path, +timezone, +umask",
                        testing all available variations. See the man page
                        section on VARIATIONS for more advanced syntax
                        options, including tweaking how certain variations
                        work.
  --vary VARIATIONS     Like --variations, but appends to previous --vary
                        values instead of overwriting them. The last value set
                        for --variations is treated implicitly as the zeroth
                        --vary value.
  --extra-build VARIATIONS
                        Perform another build with the given VARIATIONS (which
                        may be empty) to be applied on top of what was given
                        for --variations and --vary. Each occurrence of this
                        flag specifies another build, so e.g. given twice this
                        will make reprotest perform 4 builds in total.
  --auto-build          Automatically perform builds to try to determine which
                        specific variations cause unreproducibility,
                        potentially up to and including the ones specified by
                        --variations and --vary. Conflicts with --extra-build.
  --env-build           Automatically perform builds to try to determine which
                        specific environment variables cause
                        unreproducibility, based on a hard-coded whitelist and
                        blacklist. You probably want to set --vary=-all as
                        well when setting this flag; see the man page for
                        details. Conflicts with --extra-build and --auto-
                        build.
  --min-cpus NUM        Minimum CPUs to use when fixing num_cpus. Default: 1.

diff options:
  --diffoscope-arg ARG  Give extra arguments to diffoscope when running it.
                        Default: ['--exclude-directory-metadata']. Arguments
                        are {}-formatted with: {0} the name of each experiment
                        run, and {1} the path of the experiment output.
  --diffoscope PATH     Path to diffoscope(1). Default: diffoscope
  --no-diffoscope       Don't run diffoscope; instead run diff(1). Useful if
                        you don't want to install diffoscope and/or just want
                        a quick answer on whether the reproduction was
                        successful or not, without spending time to compute
                        all the detailed differences.

advanced options:
  --testbed-pre COMMANDS
                        Shell commands to run before starting the test bed, in
                        the context of the current system environment. This
                        may be used to e.g. compute information needed by the
                        build, where the computation needs packages you don't
                        want installed in the testbed itself.
  --testbed-init COMMANDS
                        Shell commands to run after starting the test bed,
                        before running anything else. Used to e.g. install
                        disorderfs in a chroot.
  --testbed-build-pre COMMANDS
                        Shell commands to run before each build, even before
                        applying variations for that build. Used to e.g.
                        install build-dependencies.
  --auto-preset-expr PYTHON_EXPRESSION
                        This may be used to transform the presets returned by
                        the auto-detection feature. The value should be a
                        python expression that transforms the _ variable,
                        which is of type reprotest.presets.ReprotestPreset.
                        See that class's documentation for ways you can write
                        this expression. Default: _
  --no-clean-on-error   Don't clean the virtual_server if there was an error.
                        Useful for debugging but will leave cruft on your
                        system depending on the virtual_server used; we hint
                        about some but there may be others.
  --dry-run             Don't run the builds, just print what would happen.
  --print-sudoers       Print a sudoers file for passwordless operation using
                        the given --variations, useful for
                        user_group.available, domain_host.use_sudo.
