pulp.app.models

class pulpcore.app.models.Artifact(*args, **kwargs)

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

  • size (models.IntegerField) – The size of the file in bytes.

  • md5 (models.CharField) – The MD5 checksum of the file.

  • sha1 (models.CharField) – The SHA-1 checksum of the file.

  • sha224 (models.CharField) – The SHA-224 checksum of the file.

  • sha256 (models.CharField) – The SHA-256 checksum of the file.

  • sha384 (models.CharField) – The SHA-384 checksum of the file.

  • sha512 (models.CharField) – The SHA-512 checksum of the file.

exception DoesNotExist
exception MultipleObjectsReturned

This accepts both a path to a file on-disk or a PulpTemporaryUploadedFile.

Parameters
  • file (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) – Keyed on the algorithm name provided by hashlib and stores the value of the expected digest. e.g. {‘md5’: ‘912ec803b2ce49e4a541068d495ab570’}

  • expected_size (int) – The number of bytes the download is expected to have.

Raises
Returns

An in-memory, unsaved Artifact

Is equal by matching digest.

Parameters

other (pulpcore.app.models.Artifact) – A artifact to match.

Returns

True when equal.

Return type

bool

q()
save(*args, **kwargs)

Saves Artifact model and closes the file associated with the Artifact

Parameters

exception MultipleObjectsReturned
save(*args, **kwargs)

Validate and save a signing service for an ASCII armored signature.

Before saving the signing service to the database, it is required to check if the service’s output corresponds to a proposed output format and creates valid signatures.

In this case, Pulp creates a file with random content, signs the file, and checks if the signature can be verified by a provided public key. If the signature was verified without errors, the signing service object is saved to the database.

Parameters

filename (str) – A relative path to a file which is intended to be signed.

Raises

RuntimeError – If a return code of the script is not equal to 0, indicating a failure.

Variables

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.

class Meta
abstract = False

Return a “Detail” model instance of this master-detail pair.

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

get_next_by_pulp_created(*, field=<django.db.models.fields.DateTimeField: pulp_created>, is_next=True, **kwargs)

pulp_type

A wrapper for a deferred-loading field. When the value is read from this object the first time, the query is executed.

class pulpcore.app.models.ProgressReport(*args, **kwargs)

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. for more info.

Relations

task – The task associated with this progress report. If left unset when save() is called it will be set to the current task_id.

class pulpcore.app.models.Publication(*args, **kwargs)

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.

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(...)
>>>             ...
>>>
exception DoesNotExist
exception MultipleObjectsReturned
classmethod create(repository_version, pass_through=False)

Create a publication.

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

Parameters
  • repository_version (pulpcore.app.models.RepositoryVersion) – The repository version to be published.

  • pass_through (bool) – 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

A created Publication in an incomplete state.

Return type

pulpcore.app.models.Publication

Notes

Adds a Task.created_resource for the publication.

delete(**kwargs)

Delete the publication.

Parameters

**kwargs (dict) – Delete options.

Notes

Deletes the Task.created_resource when complete is False.

Return type

bool

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
  • content_qs (django.db.models.QuerySet) – The queryset for Content that will be restricted further to the content present in this repository version. If not given, Content.objects.all() is used (to iterate over all content present in the repository version). A plugin may want to use a specific subclass of Content or use e.g. filter() to select a subset of the repository version’s content.

  • order_by_params (tuple of str) – 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) – 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 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")
    for content in content_batch_qs:
        ...
delete(**kwargs)
