pulp.app.models

pulpcore.app.models

BaseModel

Bases: LifecycleModel

Base model class for all Pulp models.

This model inherits from LifecycleModel which allows all Pulp models to be used with django-lifecycle.

Fields

pulp_created (models.DateTimeField): Created timestamp UTC. pulp_last_updated (models.DateTimeField): Last updated timestamp UTC.

Relations

user_roles (GenericRelation): List of user role associations with this object. group_roles (GenericRelation): List of group role associations with this object.

MasterModel(*args, **kwargs)

Bases: BaseModel

Base model for the "Master" model in a "Master-Detail" relationship.

Provides methods for casting down to detail types, back up to the master type, as well as a model field for tracking the type.

Attributes:

TYPE (str): Default constant value saved into the ``pulp_type``
    field of Model instances

Fields:

pulp_type: The user-facing string identifying the detail type of this model
Warning

Subclasses of this class rely on there being no other parent/child Model relationships than the Master/Detail relationship. All subclasses must use only abstract Model base classes for MasterModel to behave properly. Specifically, OneToOneField relationships must not be used in any MasterModel subclass.

master property

The "Master" model instance of this master-detail pair

If this is already the master model instance, it will return itself.

get_pulp_type() classmethod

Get the "pulp_type" string associated with this MasterModel type.

cast()

Return the "Detail" model instance of this master-detail object.

If this is already an instance of its detail type, it will return itself.

acast() async

Return the "Detail" model instance of this master-detail object (async).

If this is already an instance of its detail type, it will return itself.

AccessPolicy

Bases: BaseModel

A model storing a viewset authorization policy and permission assignment of new objects created.

Fields:

creation_hooks (models.JSONField): A list of dictionaries identifying callables on the
    ``pulpcore.plugin.access_policy.AccessPolicyFromDB`` which can add user or group roles
    for newly created objects. This is a nullable field due to not all endpoints creating
    objects.
statements (models.JSONField): A list of ``drf-access-policy`` statements.
viewset_name (models.TextField): The name of the viewset this instance controls
    authorization for.
customized (BooleanField): False if the AccessPolicy has been user-modified. True otherwise.
    Defaults to False.
queryset_scoping (models.JSONField): A dictionary identifying a callable to perform the
    queryset scoping. This field can be null if the user doesn't want to perform scoping.

AutoAddObjPermsMixin(*args, **kwargs)

A mixin that automatically adds roles based on the creation_hooks data.

To use this mixin, your model must support django-lifecycle.

This mixin adds an after_create hook which properly interprets the creation_hooks data and calls methods also provided by this mixin to add roles.

These hooks are provided by default:

  • add_roles_for_object_creator will add the roles to the creator of the object.
  • add_roles_for_users will add the roles for one or more users by name.
  • add_roles_for_groups will add the roles for one or more groups by name.

add_roles_for_users(roles, users)

Adds object-level roles for one or more users for this newly created object.

Parameters:

  • roles (str or list) –

    One or more roles to be added at object-level for the users. This can either be a single role as a string, or a list of role names.

  • users (str or list) –

    One or more users who will receive object-level roles. This can either be a single username as a string or a list of usernames.

Raises:

  • ObjectDoesNotExist –

    If any of the users do not exist.

add_roles_for_groups(roles, groups)

Adds object-level roles for one or more groups for this newly created object.

Parameters:

  • roles (str or list) –

    One or more object-level roles to be added for the groups. This can either be a single role as a string, or list of role names.

  • groups (str or list) –

    One or more groups who will receive object-level roles. This can either be a single group name as a string or a list of group names.

Raises:

  • ObjectDoesNotExist –

    If any of the groups do not exist.

add_roles_for_object_creator(roles)

Adds object-level roles for the user creating the newly created object.

If the get_current_authenticated_user returns None because the API client did not provide authentication credentials, no permissions are added and this passes silently. This allows endpoints which create objects and do not require authorization to execute without error.

Parameters:

  • roles (list or str) –

    One or more roles to be added at the object-level for the user. This can either be a single role as a string, or list of role names.

Domain(*args, **kwargs)

Bases: BaseModel, AutoAddObjPermsMixin

A namespace-like object applied to most Pulp models to allow for multi-tenancy.

Pulp models have a domain as a part of their uniqueness-constraint to provide isolation from other domains. Domains each have their own storage backend for storing and deduplicating Artifacts. Roles on a domain apply to all the objects in that domain.

Domains are an opt-in feature so Pulp models need to have their domain relation set the default to the "default" Domain when not enabled. Also, plugins must add domain foreign-keys to their models to be compatible with domains.

Fields

name (models.SlugField): Unique name of domain description (models.TextField): Optional description of domain storage_class (models.TextField): Required storage class for backend storage_settings (EncryptedJSONField): Settings needed to configure storage backend redirect_to_object_storage (models.BooleanField): Redirect to object storage in content app hide_guarded_distributions (models.BooleanField): Hide guarded distributions in content app

get_storage()

Returns this domain's instantiated storage class.

Relations:

remote (models.ForeignKeyField): Associated remote

AlternateContentSourcePath

Bases: BaseModel

Alternate sources of content.

Fields:

path (models.TextField): The alternate content source name.

Relations:

alternate_content_source (models.ForeignKeyField): Associated AlternateContentSource
repository (models.ForeignKeyField): Associated repository

Artifact

Bases: HandleTempFilesMixin, BaseModel

A file associated with a piece of content.

When calling save() on an Artifact, if the file is not stored in Django's storage backend, it is moved into place then.

Artifact is compatible with Django's bulk_create() method.

Fields:

file (pulpcore.app.models.fields.ArtifactFileField): The stored file. This field should
    be set using an absolute path to a temporary file.
    It also accepts `class:django.core.files.File`.

sha384 (models.CharField): The SHA-384 checksum of the file.
sha512 (models.CharField): The SHA-512 checksum of the file.
timestamp_of_interest (models.DateTimeField): timestamp that prevents orphan cleanup.
pulp_domain (models.ForeignKey): The domain the artifact is a part of.

storage_path(name)

Callable used by FileField to determine where the uploaded file should be stored.

Parameters:

  • name (str) –

    Original name of uploaded file. It is ignored by this method because the sha256 checksum is used to determine a file path instead.

before_save()

Pre-save hook that validates checksum rules prior to allowing an Artifact to be saved.

An Artifact with any checksums from the FORBIDDEN set will fail to save while raising an UnsupportedDigestValidationError exception.

Similarly, any checksums in DIGEST_FIELDS that is NOT set will raise a MissingDigestValidationError exception.

Raises:

  • class: ~pulpcore.exceptions.UnsupportedDigestValidationError: When any of the keys on FORBIDDEN_DIGESTS are set for the Artifact

  • class: ~pulpcore.exceptions.MissingDigestValidationError: When any of the keys on DIGEST_FIELDS are found to be missing from the Artifact

is_equal(other)

Is equal by matching digest.

Parameters:

  • other (Artifact) –

    A artifact to match.

Returns:

  • bool –

    True when equal.

init_and_validate(file, expected_digests=None, expected_size=None) staticmethod

Initialize an in-memory Artifact from a file, and validate digest and size info.

This accepts both a path to a file on-disk or a [pulpcore.app.files.PulpTemporaryUploadedFile][].

Parameters:

  • file ([pulpcore.app.files.PulpTemporaryUploadedFile][] or str) –

    The PulpTemporaryUploadedFile to create the Artifact from or a string with the full path to the file on disk.

  • expected_digests (dict, default: None ) –

    Keyed on the algorithm name provided by hashlib and stores the value of the expected digest. e.g. {'md5': '912ec803b2ce49e4a541068d495ab570'}

  • expected_size (int, default: None ) –

    The number of bytes the download is expected to have.

Raises:

  • [pulpcore.exceptions.DigestValidationError][] –

    When any of the expected_digest values don't match the digest of the data

  • [pulpcore.exceptions.SizeValidationError][] –

    When the expected_size value doesn't match the size of the data

  • [pulpcore.exceptions.UnsupportedDigestValidationError][] –

    When any of the expected_digest algorithms aren't in the ALLOWED_CONTENT_CHECKSUMS list

Returns: An in-memory, unsaved pulpcore.plugin.models.Artifact

from_pulp_temporary_file(temp_file) classmethod

Creates an Artifact from PulpTemporaryFile.

Returns:

touch()

Update timestamp_of_interest.

AsciiArmoredDetachedSigningService

Bases: SigningService

A model used for creating detached ASCII armored signatures.

validate()

Validate a signing service for a detached ASCII armored signature.

The validation seeks to ensure that the sign() method returns a dict as follows:

{"file": "signed_file.xml", "signature": "signed_file.asc"}

The method creates a file with some content, signs the file, and checks if the signature can be verified by the provided public key.

Raises:

  • RuntimeError –

    If the validation has failed.

Content(*args, **kwargs)

Bases: MasterModel, QueryMixin

A piece of managed content.

Fields

upstream_id (models.UUIDField) : identifier of content imported from an 'upstream' Pulp timestamp_of_interest (models.DateTimeField): timestamp that prevents orphan cleanup

Relations:

_artifacts (models.ManyToManyField): Artifacts related to Content through ContentArtifact
pulp_domain (models.ForeignKey): Pulp Domain this content lives in

repository_types() classmethod

Tuple of the repository models that can store this content type.

Populated at start up time. Read only.

natural_key_fields() classmethod

Returns a tuple of the natural key fields which usually equates to unique_together fields.

This can be overwritten in subclasses and should return a tuple of field names.

natural_key()

Get the model's natural key based on natural_key_fields.

Returns:

  • tuple –

    The natural key.

natural_key_dict()

Get the model's natural key as a dictionary of keys and values.

init_from_artifact_and_relative_path(artifact, relative_path) staticmethod

Return an instance of the specific content by inspecting an artifact.

Plugin writers are expected to override this method with an implementation for a specific content type. If the content type is stored with multiple artifacts plugin writers can instead return a tuple of the unsaved content instance and a dictionary of the content's artifacts by their relative paths.

For example::

if path.isabs(relative_path):
    raise ValueError(_("Relative path can't start with '/'."))
return FileContent(relative_path=relative_path, digest=artifact.sha256)

Parameters:

  • relative_path (str) –

    Relative path for the content

Raises:

  • ValueError –

    If relative_path starts with a '/'.

Returns:

touch()

Update timestamp_of_interest.

ContentArtifact

Bases: BaseModel, QueryMixin

A relationship between a Content and an Artifact.

Serves as a through model for the '_artifacts' ManyToManyField in Content. Artifact is protected from deletion if it's present in a ContentArtifact relationship.

sort_key(ca) staticmethod

Static method for defining a sort-key for a specified ContentArtifact.

Sorting lists of ContentArtifacts is critical for avoiding deadlocks in high-concurrency environments, when multiple workers may be operating on similar sets of content at the same time. Providing a stable sort-order becomes problematic when the CAs in question haven't been persisted - in that case, pulp_id can't be relied on, as it will change when the object is stored in the DB and its "real" key is generated.

This method produces a key based on the content/artifact represented by the CA.

Returns:

  • –

    a tuple of (str(content-key), str(artifact-key)) that can be reliably sorted on

PulpTemporaryFile

Bases: HandleTempFilesMixin, BaseModel

A temporary file saved to the storage backend.

Commonly used to pass data to one or more tasks.

Fields:

file (pulpcore.app.models.fields.ArtifactFileField): The stored file. This field should
    be set using an absolute path to a temporary file.
    It also accepts `class:django.core.files.File`.
Relations

pulp_domain (pulpcore.app.models.Domain): The domain this temp file is a part of.

storage_path(name)

Callable used by FileField to determine where the uploaded file should be stored.

Parameters:

  • name (str) –

    Original name of uploaded file. It is ignored by this method because the pulp_id is used to determine a file path instead.

init_and_validate(file, expected_digests=None, expected_size=None) staticmethod

Initialize an in-memory PulpTemporaryFile from a file, and validate digest and size info.

This accepts both a path to a file on-disk or a [pulpcore.app.files.PulpTemporaryUploadedFile][].

Parameters:

  • file ([pulpcore.app.files.PulpTemporaryUploadedFile][] or str) –

    The PulpTemporaryUploadedFile to create the PulpTemporaryFile from or a string with the full path to the file on disk.

  • expected_digests (dict, default: None ) –

    Keyed on the algorithm name provided by hashlib and stores the value of the expected digest. e.g. {'md5': '912ec803b2ce49e4a541068d495ab570'}

  • expected_size (int, default: None ) –

    The number of bytes the download is expected to have.

Raises:

  • [pulpcore.exceptions.DigestValidationError][] –

    When any of the expected_digest values don't match the digest of the data

  • [pulpcore.exceptions.SizeValidationError][] –

    When the expected_size value doesn't match the size of the data

  • [pulpcore.exceptions.UnsupportedDigestValidationError][] –

    When any of the expected_digest algorithms aren't in the ALLOWED_CONTENT_CHECKSUMS list

Returns:

RemoteArtifact

Bases: BaseModel, QueryMixin

Represents a content artifact that is provided by a remote (external) repository.

Remotes that want to support deferred download policies should use this model to store information required for downloading an Artifact at some point in the future. At a minimum this includes the URL, the ContentArtifact, and the Remote that created it. It can also store expected size and any expected checksums.

Fields:

url (models.TextField): The URL where the artifact can be retrieved.
size (models.BigIntegerField): The expected size of the file in bytes.
md5 (models.CharField): The expected MD5 checksum of the file.

sign(filename, env_vars=None)

Signs the file provided via 'filename' by invoking an external script (or executable).

The external script is run as a subprocess. This is done in the expectation that the script has been validated as an external signing service by the validate() method. This validation is currently only done when creating the signing service object, but not at the time of use.

Parameters:

  • filename (str) –

    A relative path to a file which is intended to be signed.

  • env_vars (dict, default: None ) –

    dictionary of environment variables

Raises:

Returns:

  • –

    A dictionary as validated by the validate() method.

asign(filename, env_vars=None) async

Async version of sign.

validate()

Ensure that the external signing script produces the desired behaviour.

With desired behaviour we mean the behaviour as validated by this method. Subclasses are required to implement this method. Works by calling the sign() method on some test data, and verifying that any desired signatures/signature files are returned and are valid. Must also enforce the desired return value format of the sign() method.

Raises:

  • RuntimeError –

    If the script failed to produce the desired outcome for the test data.

save(*args, **kwargs)

Save a signing service to the database (unless it fails to validate).

Bases: MasterModel

A Distribution defines how the Content App distributes a publication or repository_version.

This master model can be used by plugin writers to create detail Distribution objects.

The name must be unique.

The base_path must have no overlapping components. So if a Distribution with base_path of a/path/foo existed, you could not make a second Distribution with a base_path of a/path or a because both are subpaths of a/path/foo.

Subclasses are expected to use either the publication or repository_version field, but not both. The content app that serves content is not prepared to serve content both ways at the same time.

    The path being requested

Returns: Empty dictionary, or a dictionary with HTTP Response header/value pairs.

invalidate_cache()

Invalidates the cache if enabled.

Publication(*args, **kwargs)

Bases: MasterModel

A publication contains metadata and artifacts associated with content contained within a RepositoryVersion.

Using as a context manager is highly encouraged. On context exit, the complete attribute is set True provided that an exception has not been raised. In the event and exception has been raised, the publication is deleted.

Fields

complete (models.BooleanField): State tracking; for internal use. Indexed. pass_through (models.BooleanField): Indicates that the publication is a pass-through to the repository version. Enabling pass-through has the same effect as creating a PublishedArtifact for all of the content (artifacts) in the repository.

Relations

repository_version (models.ForeignKey): The RepositoryVersion used to create this Publication. pulp_domain (models.ForeignKey): The domain the Publication is a part of.

Examples:

>>> repository_version = ...
>>>
>>> with Publication.create(repository_version) as publication:
>>>     for content in repository_version.content():
>>>         for content_artifact in content.contentartifact_set.all():
>>>             artifact = PublishedArtifact(...)
>>>             artifact.save()
>>>             metadata = PublishedMetadata.create_from_file(...)
>>>             ...
>>>

repository property

Return the associated repository

Returns:

  • –

    pulpcore.app.models.Repository: The repository associated to this publication

create(repository_version, pass_through=False) classmethod

Create a publication.

This should be used to create a publication. Using Publication() directly is highly discouraged.

Parameters:

  • repository_version (RepositoryVersion) –

    The repository version to be published.

  • pass_through (bool, default: False ) –

    Indicates that the publication is a pass-through to the repository version. Enabling pass-through has the same effect as creating a PublishedArtifact for all of the content (artifacts) in the repository.

Returns:

  • –

    pulpcore.app.models.Publication: A created Publication in an incomplete state.

Notes

Adds a Task.created_resource for the publication.

    Delete options.

Notes

Deletes the Task.created_resource when complete is False.

finalize_new_publication()

Finalize the incomplete Publication with plugin-provided code.

This method should be overridden by plugin writers for an opportunity for plugin input. This method is intended to be used to validate or modify the content.

This method does not adjust the value of complete, or save the Publication itself. Its intent is to allow the plugin writer an opportunity for plugin input before pulpcore marks the Publication as complete.

Returns:

  • –

    django.db.models.QuerySet: The content that is contained within this version.

Examples:

>>> repository_version.get_content(content_qs=File.objects)):

content_batch_qs(content_qs=None, order_by_params=('pk'), batch_size=1000)

Generate content batches to efficiently iterate over all content.

Generates query sets that span the content_qs content of the repository version. Each yielded query set evaluates to at most batch_size content records. This is useful to limit the memory footprint when iterating over all content of a repository version.

.. note::

* This generator is not safe against changes (i.e. add/remove content) during
  the iteration!

* As the method uses slices internally, the queryset must be ordered to yield
  stable results. By default, it is ordered by primary key.

Parameters:

  • order_by_params (tuple of str, default: ('pk') ) –

    The parameters for the order_by clause for the content. The Default is ("pk",). This needs to specify a stable order. For example, if you want to iterate by decreasing creation time stamps use ("-pulp_created", "pk") to ensure that content records are still sorted by primary key even if their creation timestamp happens to be equal.

  • batch_size (int, default: 1000 ) –

    The maximum batch size.

Yields:

  • –

    [django.db.models.QuerySet][]: A QuerySet representing a slice of the content.

Example

The following code could be used to loop over all FileContent in repository_version. It prefetches the related pulpcore.plugin.models.ContentArtifact instances for every batch::

repository_version = ...

batch_generator = repository_version.content_batch_qs(
    content_class=FileContent.objects.all()
)
for content_batch_qs in batch_generator:
    content_batch_qs.prefetch_related("contentartifact_set")

GroupProgressReport

Bases: BaseModel

A model for all progress reporting in a Task Group.

All progress reports have a message, code and are related to a Task Group.

Once a Task Group is created, plugin writers should create these objects ahead. For example:

>>> task_group = TaskGroup(description="Migration Sub-tasks")
>>> task_group.save()
>>> group_pr = GroupProgressReport(
>>>     message="Repo migration",
>>>     code="create.repo_version",
>>>     task_group=task_group).save()

Taks that will be executing certain work, and is part of a TaskGroup, will look for the Task group it belongs to and find appropriate progress report by its code and will update it accordingly.

For example:

>>> task_group = TaskGroup.current()
>>> progress_repo = task_group.group_progress_reports.filter(code='create.repo_version')
>>> progress_repo.update(done=F('done') + 1)

To avoid race conditions/cache invalidation issues, this pattern needs to be used so that operations are performed directly inside the database:

.update(done=F('done') + 1)

See: https://docs.djangoproject.com/en/3.2/ref/models/expressions/#f-expressions Important: F() objects assigned to model fields persist after saving the model instance and will be applied on each save(). Do not use save() and use update() instead, otherwise refresh_from_db() should be called after each save()

Fields:

message (models.TextField): short message for the progress update, typically
    shown to the user. (required)
code (models.TextField): identifies the type of progress report
total: (models.IntegerField) The total count of items to be handled
done (models.IntegerField): The count of items already processed. Defaults to 0.
suffix (models.TextField): Customizable suffix rendered with the progress report
    See `the docs <https://github.com/verigak/progress>`_. for more info.

Relations:

task_group: The task group associated with this group progress report.

ProgressReport

Bases: BaseModel

A model for all progress reporting.

All progress reports have a message, state, and are related to a Task.

Plugin writers should create these objects to show progress reporting of a single step or aspect of work which has a name and state. For example:

>>> ProgressReport(
>>>     message='Publishing files', code='publish', total=23
>>> )  # default: state='waiting' and done=0

>>> ProgressReport(
>>>     message='Publishing files', code='publish', total=23, state='running'
>>> )  # specify the state
>>> ProgressReport(
>>>     message='Publishing files', code='publish', total=23, done=16
>>> )  # already completed 16

Update the state to COMPLETED and save it:

>>> progress_bar = ProgressReport(
>>>     message='Publishing files', code='publish', total=23, state='running'
>>> )
>>> progress_bar.state = 'completed'
>>> progress_bar.save()

The ProgressReport() is a context manager that provides automatic state transitions and saving for the RUNNING CANCELED COMPLETED and FAILED states. The increment() method can be called in the loop as work is completed. When ProgressReport() is used as a context manager progress reporting is rate limited to every 500 milliseconds. Use it as follows:

>>> progress_bar = ProgressReport(
>>>     message='Publishing files', code='publish', total=len(files_iterator)
>>> )
>>> progress_bar.save()
>>> with progress_bar:
>>>     # progress_bar saved as 'running'
>>>     for file in files_iterator:
>>>         handle(file)
>>>         progress_bar.increment()  # increments and saves
>>> # progress_bar is saved as 'completed' if no exception or 'failed' otherwise

A convenience method called iter() allows you to avoid calling increment() directly:

>>> progress_bar = ProgressReport(
>>>     message='Publishing files', code='publish', total=len(files_iterator)
>>> )
>>> progress_bar.save()
>>> with progress_bar:
>>>     for file in progress_bar.iter(files_iterator):
>>>         handle(file)

You can also use this short form which handles all necessary save() calls:

>>> data = dict(message='Publishing files', code='publish', total=len(files_iterator))
>>> with ProgressReport(**data) as pb:
>>>     for file in pb.iter(files_iterator):
>>>         handle(file)

ProgressReport objects are associated with a Task and auto-discover and populate the task id when saved.

When using threads to update a ProgressReport in parallel, it is recommended that all threads share the same in-memory instance. Django does not synchronize in-memory model instances, so multiple instances of a specific ProgressReport will diverge as they are written to from separate threads.

Fields:

message (models.TextField): short message for the progress update, typically
    shown to the user. (required)
code (models.TextField): identifies the type of progress report
state (models.TextField): The state of the progress update. Defaults to `WAITING`. This
    field uses a limited set of choices of field states. See `STATES` for possible states.
total: (models.IntegerField) The total count of items to be handled
done (models.IntegerField): The count of items already processed. Defaults to 0.
suffix (models.TextField): Customizable suffix rendered with the progress report
    See `the docs <https://github.com/verigak/progress>`_. for more info.
