Mayan EDMS v4.3.1 Release Notes

• • 🛠 Fixes and improvements merged from version 4.2.9 and 4.2.10.

Previous changes from v4.3

• • ⚡️ Partials navigation updates:

    • Streamline JavaScript partials navigation code.
    • Make the AJAX response redirect code configurable. New setting APPEARANCE_AJAX_REDIRECTION_CODE added.
    • Remove repeated AJAX redirection middleware.

  • ➕ Add white outline to favicon.

  • Add support for optional get_mayan_object_permissions and get_mayan_view_permissions methods to allow API views to customize how required permissions are calculated.

  • ➕ Added support for form fieldsets.

  • ➕ Added fieldsets to the following forms:

    • document file properties
    • document type deletion policies
    • metadata type
    • user

  • ✂ Remove usage of flat values_list queryset in metadata managers module.

  • ✅ Prefix all test objects with an underscore to avoid clashes with test methods.

  • PartialNavigation.js improvements.

    • Clean URL query on form submit and use form data as the URL query.
    • Remove dead code.
    • Use constants where appropriate.

  • ⚡️ Search updates:

    • Add filtering support to list views. All list view that show instances of models with a corresponding defined search model, will show a text box for filtering the list. The syntax is the same as the standard simple search.
    • Empty list views now show the toolbar for cases where the list is empty due to a filtering term.
    • Define the q URL query key as an internal literal named QUERY_PARAMETER_ANY_FIELD.

  • 👌 Support AJAX request cancellation. This avoid the user interface from appearing to unresponsive when the backend is overloaded.

  • 👌 Support AJAX request throttling. Prevents users from requesting too many consecutive page loads. Defaults to a maximum of 10 requests in 5 seconds of less. This applies only to the user interface. The AJAX throttling resets the moment the last pending AJAX request is completed.

  • BaseBackend class improvements.

    • Selectable identifier via the _backend_identifier property. Defaults to backend_class_path for compatibility.
    • Update .get_all to return a list and not a dictionary.
    • Add property backend_id that returns the value of the class _backend_identifier property.

  • Convert document file actions from hardcoded logic to an extensible class using the BaseBackend class. Available classes will be loaded from the document_file_actions module. The id of the class defaults to the existing literal values for compatibility.

  • Add API endpoint called document_file_actions to list the available actions and their properties. API endpoint URL: /api/v4/document_file_actions/

  • ➕ Add document version modification backend. Convert the document version page reset and append functions into document version modication backends. Update document version views and API endpoints to use document version modification backends. Adds new API endpoints:

    • /api/v4/documents/{ ID }/versions/{ ID }/modify/
    • /api/v4/document_version_modification_backends/

  • ➕ Add workflow action to send user messages.

  • ⚡️ Update WorkflowAction to use common.classes.BaseBackend.

  • 🔨 Pagination refactor:

    • Remove django-pure-pagination package.
    • Use Django's 3.2 new get_proper_elided_page_range for paging.
    • Remove duplicate URL query string manipulation.
    • Remove duplicated pagination template.
    • Make pagination argument configurable. Added the setting VIEWS_PAGING_ARGUMENT. Defaults to page for compatibility.

  • ⚡️ Update the default pagination size from 40 items to 30.

  • 👌 Support hyphenated text when using the ElasticSearch backend.

  • ➕ Add support for supplying files to source backend via the API. Add the accept_files property to SourceBackendAction which dynamically add a file serializer field for the corresponding action.

  • ➕ Add an upload action to the web form source. This allows using web form sources to upload documents from the API.

  • 👌 Support REST API list filtering. Filtering is done using similar logic to that of the user interface list filtering. However, the API list filtering also support filtering by any field and not just using the special "any field" q query key.

  • 🔀 Merge fixes from version 4.2.2.

    • Document index instance nodes
    • Workflow transition triggers
    • File caches
    • Quotas

  • ⏪ Convert API search model names to lowercase to revert backward incompatible change in version 4.2. Search model names via the API can now be specified in either lowercase (version 4.2) or hybrid case (version <4.2).

  • mkdtemp now accepts a dir argument like the upstream version. However the dir value is appended to the system wide value of STORAGE_TEMPORARY_DIRECTORY.

  • ⚡️ Staging folder updates:

    • Support inclusion regular expression.
    • Support exclusion regular expression.
    • Support subfolders.
    • Update scan code to use pathlib.Path.
    • Support pagination.

  • ➕ Add support for workflow escalation. This feature allows moving a workflow forward after the workflow has remained in a certain state after a pre-determined amount of time. Multiple escalations are supported for each state. Conditions using the templating language are supported.

  • 🚚 Move model based classes to the databases app. Move the classes:

    • ModelQueryFields
    • ModelAttribute
    • ModelProperty
    • ModelField
    • ModelFieldRelated
    • ModelReverseField
    • QuerysetParametersSerializer

  • 🌲 Convert the OCR app to the new error log system. The permission "View error log" is now required to view the document version OCR error log.

  • 📜 Convert the document parsing app to the new error log system. The permission "View error log" is now required to view the document file parsing error log.

  • ✂ Remove the Python package mock. This package is now available as unittest.mock in Python 3.3 onward.

  • 🚚 Unify and remove repeated workflow API views code using parent resolution mixins.

  • 👌 Support adding help text to search model fields. By default the help text from the model fields will be used.

  • Increase the document type label size from 96 characters to 196.

  • ⚡️ Update the document type label field help text.

  • ⚡️ Search updates:

    • Rename search model instances from "...search" to "search_model...".
    • Add support for removing search fields from third party apps. The method is called .remove_search_field(search_field=) and requires the search field instance obtained from the method .get_search_fields().
    • Remove the search_fields list and use the search_fields_dict instead for both purposes. The canonical method to obtain the search field of a search model is now using the method .get_search_fields().

  • ⚡️ Update the ElasticSearch backend default settings to match those of the official Python client.

  • Don't introspect document file MIME type at download. Instead pass the stored values.

  • 👌 Support empty ranges for parse_range.

  • ➕ Add group_iterator to group iterators in to lists of tuples.

  • 🔨 Refactor bulk object search indexing:

    • Rename mayan.apps.dynamic_search.tasks.task_index_search_model to mayan.apps.dynamic_search.tasks.task_index_instances.
    • Index only objects that exists instead of using blind ranges.
    • Update search_index_objects management command to trigger multiple task_index_instances tasks instead of just one.

  • ➕ Add date manipulation template tags. The new tags are date_parse to convert a string into a datetime object and timedelta to apply time transformations to a datetime object.

  • ➕ Add a size field to the document file model. Since this value is not expected to change, it is now a persistent model field and not calculated on demand by querying the storage layer. This change also improves document mirroring performance by removing one disk access per document and using the database stored size value which is immutable.

  • 👌 Support searching messages. Make the subject, body, date_time fields searchable.

  • ⚡️ Error logging updates:

    • Add error log entry delete permission.
    • Add support deleting individual error log entries or the complete error log of an object.
    • Add the error log entry delete event.
    • Support subscribing to the error log entry delete event of an object.
    • Add API views. Support added to view the error log of objects.

  • 💅 Migrations code style cleanup.

    • Rename code migrations functions prefix from operation_ to code_.
    • Add keyword arguments.
    • PEP8 code style cleanups.

  • ➕ Add support for cabinet mirroring.

  • ✂ Remove django-colorful. Use HTML5 color field instead.

  • ➕ Add support to randomize the tag color.

  • ⚡️ Document parsing updates. Closes GitLab issue #957. Thanks to LeVon Smoker (@lsmoker) for the report and initial suggestions.

    • Pass the original document file to parsers instead of attempting to pre-processing the document file to PDF.
    • Add parsing support for office document files and text files.

  • ✅ Rename test file literals for uniformity.

  • 📇 Rename management commands to include the app name where they are defined. Add a stub command for backwards compatibility.

    • checkdependencies replaced by dependencies_check.
    • checkversion replaced by dependencies_check_version.
    • createautoadmin replaced by autoadmin_create.
    • generaterequirements replaced by dependencies_generate_requirements.
    • initialsetup replaced by common_initial_setup.
    • installdependencies replaced by dependencies_install.
    • mountindex replaced by mirroring_mount_index.
    • performupgrade replaced by common_perform_upgrade.
    • platformtemplate replaced by platform_template.
    • preparestatic replaced by appearance_prepare_static.
    • purgelocks replaced by lock_manager_purge_locks.
    • purgepermissions replaced by permissions_purge.
    • purgeperiodictasks replaced by task_manager_purge_periodic_tasks.
    • purgestatistics replaced by statistics_purge.
    • revertsettings replaced by settings_revert.
    • savesettings replaced by settings_save.
    • showsettings replaced by settings_show.
    • showversion replaced by dependencies_show_version.

  • Split the document indexing models module. Module is split into index template and instance models.

  • 👉 Show item count even if the list is empty. This change prevents the list toolbar from "jumping" visually when there are no results.

  • Simplify how the view title is copied to the window title. Escaping is now performed by jQuery.

  • ➕ Add icons to all views. Every view now has a corresponding icon to be displayed with the title.

  • Normalize icon, link and view names. Follow the pattern object_sub_object_action.

  • ➕ Add warning message when user attempting to delete their own accounts.

  • ➕ Add support for Whoosh bulk indexing using the BufferedWriter class. When reindexing the search indexes, for every lock obtained, a group of object will be written as a single operation. The number of objects written concurrently is controlled by the settings SEARCH_INDEXING_CHUNK_SIZE.

  • Split converter app views into separate modules.

  • ➕ Add support for transformation argument forms.

  • 👌 Improve transformation argument column display.

  • 🛠 Fix argument handling for the transformation TransformationDrawRectangle.

  • Check and reject negative percent values for the zoom transformation.

  • 🛠 Fix asset transformations hash calculation.

  • 👀 Use a lower layer that the redaction layer to allow seeing the entire document when editing redactions. This is more natural as it gives the impression the redaction is actually being edited by being moved instead of showing two redactions (old in the image plus the interactive one).

  • ➕ Add transparency support to the TransformationDrawRectanglePercent transformation.

  • Unify the TransformationDrawRectangle and TransformationDrawRectanglePercent transformations.

  • 🚚 Move transformation mixins to their own module.

  • 👍 Allow classes using APIImageViewMixin to specify the stream MIME type via get_stream_mime_type.

  • 🛠 Fix repeated model manager definition in the DocumentFilePage model.

  • 👌 Support easier test document stub creation via the new auto_create_test_document_stub. It is mutually exclusive with auto_create_test_document_stub and requires settings auto_upload_test_document to False.

  • ➕ Add first name and last name fields to the test case user.

  • Generalize image transformations into reusable mixins: ImagePasteCoordinatesAbsoluteTransformationMixin, ImagePasteCoordinatesPercentTransformationMixin, ImageWatermarkPercentTransformationMixin.

  • ➕ Add support for signature capture. The signature capture app allows capture of handwritten signatures. The original point data as well as an SVG version of the signature is store. The point data represents the raw signature primitives that allows reloading them into the signature pad library. The SVG version allows for rendering as an image for preview. A transformation is added to allow pasting a signature as a page image.

  • ✂ Remove trailing new lines from the MIME type and encoding returned by the MIMETypeBackendFileCommand.

  • 0️⃣ Make MIMETypeBackendFileCommand the default MIME backend.

  • 🛠 Fix sorting and grouping of permissions in the workflow action to grant or revoke document access.

  • ✂ Remove SearchModel unused class method and improve result sorting.

  • ⚡️ Navigation updates:

    • Add support for extra HTML attributes.
    • Improve HTML data by allowing the entries to be resolved against the context.
    • Support empty URL values. When empty, the link is rendered without a href attribute.

  • ➕ Add link to make staging folder file selection easier. Closes GitLab issue #341. Thanks to Leroy Förster (@gersilex) for the report and initial idea.

  • Modernize Python syntax:

    • Pass generators instead of lists to sorted.
    • Update string formatting to use .format.
    • Remove creating of sets using the set factory and use instead the set literal.

  • 🆕 New workflow events: workflow instance created committed when a new workflow is launched for a document and workflow instance transitioned committed when a workflow instance is transitioned to a new state, either manually or automatically.

  • Track the user when a new workflow instance is created or transitioned.

  • ⚡️ Optimize the document indexing by reusing the index instance node if it already exists.

  • ➕ Add support for document index event triggers. Historically document indexes used hard coded signals to trigger an index update. The indexing app was updated to now use events to trigger these updates. This has the additional benefits of allowing runtime configuration of the index event triggers, disabling the ones not relevant for an index to improve performance. New document indexes default to update on all available document events. Existing indexes will me automatically migrated and updated to update on all available document events. Index updates now support more events like adding or removal from cabinets. Closes GitLab issue #631. Thanks to Tobias Huhn (@twhuhn) for the request.

  • Convert the staging folder file selection input to a Select2 widget supporting text filtering.

  • 🚚 Move the transformations TransformationDrawRectangle and TransformationDrawRectanglePercent to the decorations layer.

  • ➕ Add retry backoff maximum delay to the search tasks.

  • ➕ Add per user object event subscription view.

  • ➕ Add support for permission filtering to the notification views. This moves the access filtering of notification from the class to the view. The advantage of this change is that notifications are restricted when the access control is modified, even if the notification already exists.

  • Normalize how the search "Match all" parameter is evaluated.

  • 🛠 Fix evaluation of "Match all" when using a single level scoped search.

  • 👍 Discard non supported images contained in MPO images files.

  • 👉 Use the ElasticSearch count API (https://www.elastic.co/guide/en/elasticsearch/reference/current/cat-count.html) to obtain accurate search model status information.

  • ✂ Delete existing indexes when calling the ElasticSearch backend initialize method.

  • 👻 Wrap search backend errors into a general exception with a short explanation.

  • 📚 Documentation updates:

    • Set the Docker Compose installation method as the main method.
    • Add warning notes for the deprecated installation methods.
    • Expand the requirements section.
    • Move the requirements to their on chapter.
    • Update the features part.

  • Add management command common_generate_random_secret_key to provide random values suitable for use as SECRET_KEY.

  • 🔨 Refactor initial setup and upgrade commands:

    • Consolidate management command code.
    • Move command code to a separate class.
    • Convert code to use pathlib.

  • ➕ Add support for disabling use of the media folder. Add the bootstrap setting COMMON_DISABLE_LOCAL_STORAGE to disable use of the local media folder. When using this setting, all apps must be also configured via their respective storage backend settings to use alternate persistence methods.

  • When serving images using APIImageViewMixin, detect the MIME type of the data before sending the stream. This ensures the image will load correctly in all browsers that require a MIME type value in the header of the stream.

  • 🔄 Change the UUID field to ElasticSearch field mapping, from Keyword to Text to avoid search indexing error when processing document containers with more than 910 documents. ElasticSearch's Keyword field is limited to 32766 bytes and attempting to index a container with more than 910 documents would exceed this limit.

  • ⚡️ Update the ElasticSearch backend search query configuration to be more strict and lower the number of hits matched. Change the match query to match_phrase and remove the fuzzy query.

  • Ensure document version pages point to an existing content object when exporting. Otherwise they are skipped.

  • 👌 Improve document version export code to skip invalid pages. The page loop will skip pages with no content object and regard the first page found with a content object as the first exported page.

  • Don't assume all storages have a preset mode attribute. Such is the case with the S3Boto3Storage when used for shared uploaded files. Instead introspect the mode and fallback to a safe default valur of 'rb'.

  • Disable the settings edit link when local storage is disabled.

  • ⚠ Display a warning message in the setting edit view when local storage is disabled.
