Version 2.5

Released: July 07, 2017

Changes

OCR text download

A link and view were added to download the entire OCR text of a document as a separate file. The link can be found under the “Actions” dropdown when the “OCR” tab of a document is selected.

SANE document source

A validation error was being raised when the resolution field of the SANE document source was left blank. This issue has been fixed and works as expected now.

Mailing profiles

Previously, the way documents were emailed was controlled by configuration settings that only system administrator could change as the OS level. It is now possible to create mailing profiles from within the user interface. This allows for Mayan administrators to add mailing profiles without the intervention system administrators. It also provides the opportunity to create multiple mailing profiles. This is useful for sending documents via different email providers depending on things like priority of delivery, or email size limitations. For multi-tenant environments, this also means that each tenant can now send documents via email with their own respective email accounts. For system administrators, this means there is no longer a need to rely on a single email profile for the entirety of all the tenants in a deployment, which could be taxing email quota limits or triggering spam filters. For more information on the multi-tenant plugin visit the Mayan app store at: http://www.mayan-edms.com/store/

New transformation

A lineart transformation was added to reduce the amount of colors in a document’s image to just 2. This is useful to increase the OCR accuracy on some kind of documents whose color or layout may confuse the OCR engine and lower the accuracy of the text recognition.

UI reorganization

The main menu was been reorganization for clarity of function. The “About” menu has been renamed to “System” to signify that the items in this menu relate to system configuration topics. The “Tools” and “Setup” sub-menus, were moved from the “Profile” menu to the new “System” menu. The “Profile” menu has been renamed to “User”. Additionally, the “User” menu is now part of the main menu instead of floating right on the layout. This change along with others improve the usability on small devices like tablets and smartphones.

PDF compatibility updates

Support for non-compliant, “broken”, and PDFs encrypted with no passwords has been added. Previously no effort was made to process the images for these files. The code for detecting the number of pages in a PDF has also been improved to retry several methods when failing on non-compliant PDF documents.

Office documents compatibility updates

Improvements to the Libre Office conversion code were added, including a workaround for Libre Office bug #37531 (https://bugs.documentfoundation.org/show_bug.cgi?id=37531) which sometimes manifested when uploading multiple office documents sequentially.

Metadata setup UI improvements

A new widget to define the document type to metadata type relationship has been added. The new widget provides a method to switch between required metadata and optional metadata for a document type. This new method is not only faster but does not force users to remove a metadata type before making the switch and thus avoid deletion of existing metadata entries. A new view was also added to change the document type to metadata type relation not only the document type view but also from the metadata type view eliminating travel between these two views when creating new metadata types and assigning them to document types.

Duplicated document scanning

Support to scan and list duplicated document scanning was added in the form of a new document list link under the “Documents” main menu. Every time a document is uploaded, a document scan will be triggered to determine if the new document is a duplicate of an existing document. Duplicate documents will be listed in a new “Duplicated documents” link in the main menu. A full document list scan can also be triggered by using the new “Duplicated document scan” button in the tools menu. Finally, a new tab in the document view has been added called “Duplicates” that will list all duplicates of the currently selected document when in the document’s view. Related to this feature is the addition of being able to search documents by their checksum. This was done by indexing the checksum database field and by adding the checksum as a search field in the advanced document search view and via the API.

Login session control

Support was added to control the length of time a log in session lasts. First from the user interface side of things a “Remember me” checkbox was added to the log in form that will cause the session to persist after the browser is closed. If this checkbox is left blank the session will be destroyed when the browser closes and the user will need to log in again when accessing any of the URLs. The second part of this feature is for administrators. The configuration setting AUTHENTICATION_MAXIMUM_SESSION_LENGTH was added to control the maximum time a logged in session will persist when users click the “Remember me” checkbox. The default of this setting is 30 days.

Document image cache disabling

It is now possible to disable the document page image caching. The document image cache works on two level and hence two setting options were added. The first is the DOCUMENTS_DISABLE_BASE_IMAGE_CACHE option which disables the first layer of caching, the generation of a master image file for each document page. This means that subsequent request for a page’s image will trigger the conversion of the document from its original uploaded file. The second option, DOCUMENTS_DISABLE_TRANSFORMED_IMAGE_CACHE, disables just the caching of the transformed (rotated, resized, zoomed) images of document pages. The settings can be used together or separately depending on how much disk space saving is desired. These settings give control over the trade-off between disk space savings and higher CPU utilization. These settings are ideal for installations with a lot of documents, that want to conserve disk space, and have CPU capacity to spare. Multi-tenant installations can also benefit from these new settings.

Document filter by workflow state

A few versions over, a main menu item was added to list documents by their workflow and/or their current workflow state. Support for filtering by the initial workflow state has been added to this feature.

Support for restoring forgotten password

Views and templates were added to enable the typical “Forgotten password” worflow using a signed token via email.

Other Changes

  • Add missing OCR migration.
  • Improve error output of the performupgrade command to debug upgrade errors that could stop an upgrade (missing document files, etc).
  • Enable the django-mathfilters app added in version 2.4.
  • Do a complete pull and synchronization of the translations to fix missing translations for Polish. Thanks to Wojtek Warczakowski for the report.
  • Allow null for the SANE source resolution field. Even though the field was marked as allowing blank values it was failing because it is a number field and number fields need to allow explicit null values when left blank.
  • Rename the mayan_task_manager app to task_manager.
  • Make the task manager translatable.
  • Add Turkish to the list of processes languages.
  • Use Toastr libary for screen messages.
  • Reduce verbosity of some debug messages in the MayanAppConfig, settings and, mailing discovery.
  • Make sure lookup selection widgets also trigger the metadata update checkbox on change.
  • Usability improvements on small displays.
  • Removal of the CONVERTER_LIBREOFFICE_PATH and CONVERTER_PDFTOPPM_PATH settings. These setting have been consolidated into CONVERTER_GRAPHICS_BACKEND_CONFIG.
  • Improve the documentation of the document creation API endpoint. GitHub issue #255. Thanks to @lcerliani opening the issue.
  • Libre Office conversion improvements. Give every libreoffice instance its own separate $HOME directory. Additionally give every libreoffice its own UserInstallation file in the $HOME directory. Works around Libre Office issue: https://bugs.documentfoundation.org/show_bug.cgi?id=37531 Solves or affects GitLab issues #393 #258 #198 #175
  • The trashed document deletion action is now a background task. This feature results is much faster trashed document deletion and trash can emptying.
  • Remove animated spinners to lower browser memory usage and increase responsiveness.
  • Render a document page placeholder while the real document page loads. This change avoids “jumping” effect when loading many thumbnails.
  • Increase lazy load thresholds. More thumbnails and document pages will be loaded and visible by default when a view loads.
  • Improve usability and appearance on medium and small devices like tablets and smartphones.
  • Do hard word break on form titles to avoid horizontal scroll on small displays.
  • Python3 compatilibty improvements by removing all explicit conversion using the unicode() function.
  • Unicode handling improvements.
  • Update required versions of Pillow and django-suit.
