Title:
Mahara 1.9 Fails to Record Correct Mime Types on Leap2 Import or
Moodle Export
Status in Mahara ePortfolio:
New
Bug description:
We're running Moodle 2.6.2 and Mahara 1.9 on Linux with MySQL.
When a user opts to export a discussion forum post to Mahara in HTML
format, the post turns up in the user's Content/Files/incoming folder,
but it *fails to appear* for selection in the listing of files
available through the "Some HTML" plugin. Downloading the file from
the content area verifies that it actually has been written correctly,
but even though it appears in the content it remains unavailable in
the listing of file for selection in the "Some HTML" plugin.
(Discussion posts that had been uploaded while we were running Mahara
1.8x *do* appear in that list of files--only forum posts exported
since the Mahara 1.9 upgrade fail to appear.)
A look at the Artefact_File_Files table shows that the earlier
exported posts were, under Mahara 1.8x, identified with a mime type of
text/html, but that the posts appearing since our Mahara 1.9 upgrade
are being mapped as application/x-director. [Changing that mime type
to text/html in the table has the effect of making the content
visible, as it should be, in the file selector.]
The problem also appears when a Leap2 file is imported into the
system. While an imported *page* displays its associated imported
content without any problems, the content itself shows the same mime
problems: quicktime movies, pdf files, all seem to be misidentified,
with the result that they appear in the content area, but cannot be
selected for use on any other pages: the associated plugins ("PDF" and
"Embedded Media") fail to show in their file selection windows that
any pdf or mov files exist.
These problems were *not* at hand with our earlier Mahara 1.8x
installation, and, insofar as both seem tied to the mapping of the
files in the Artefact_File_Files table, both seem to share a common
issue, pointing to the way that mime types get recorded in Mahara 1.9.
