- function get_mimetypes_array() now contains also information about filetype groups and language strings
- use 'smart' human-readable mimetype description
- never determine filetype group based on filetype icon image! remove function mimeinfo_from_icon()
- get rid of class filetype_parser and file lib/filestorage/file_types.mm, replaced with functions file_get_typegroup(), file_extension_in_typegroup() and file_mimetype_in_typegroup()
- support multiple icon sizes, not only 16 and 32
- retrieve filetype icon only using proper functions file_..._icon() from lib/filelib.php throughout the code
- increase size of repository thumbnails to 90 and icons to 24 (will take effect when new icons exist)
Portfolio API code in the assignment module expected that the current
user is the author of the submission. Therefore the "Export to
portfolio" button did not work when the submission was viewed by a
teacher (eg at the page with the list of all submissions in the Advanced
upload assignment).
This patch introduces a new callback argument 'submissionid' that holds
explicit ID of the submission the export deals with. With it available,
we do not need to expect the current user is the author of the
submission.
The patch also cleans some strings used for portfolio callback
exceptions.
When this code was used as a part of the grading screen, the default
PORTFOLIO_ADD_FULL_FORM widget led to nested form elements. This patch replaces
the form widget with a plain text link that can be embedded safely.
