For Dataformats that support exporting HTML content, provide an API for
converting images within that content to something suitable for the format.
This fixes an issue with the PDF writer when it encountered a pluginfile.php
image, which it tried to request via HTTP without an active session. This
resulted in a 303 header returned by Moodle instead of the actual image,
causing an exception in the underlying TCPDF library.
In the get_grade_letters there is a static variable that is used
to cache grade letters, we should use MUC for this so that it is
reset properly between unit tests.
Completed support for all join types (any/all/none) for enrolment
method and status filtering. This includes handling forced status
filtering where a user does not have the capability to view suspended
users, as well as handling front page (whole site) participants page.
The last access implementation also fixes an existing bug,
where it was assumed never accessed would be 0, when it also needed to
handle null to return correct results. Related userlib unit tests also
updated to reflect this, as well as some incorrect comment wording.
Temporarily defaulting filtersets and their filters to join type ALL
for backwards compatibility, so the existing participants unified
filter continues to function consistently. This will be reverted once
the new participants filter UI replaces the existing unified filter.
Create a new method in the helper to use in the player,
in the external WS and in the API. Also, add a
new method in API to help to get export information
by other WS.
Previously, if the RSS feed (extests) was being served locally,
CFG->proxybypass was applied and causing the test to fail (proxy
ignored).
In that exact test we need the configured proxy to be applied
always, because the test is exaclty about detecting the problem
when a wrong proxy is used.
* Exporting via Oracle trims trailing zeroes in floating numbers which
results to a smaller file size for the exported file. Better to reduce
the minimum expected export file size from 4000 bytes to 3900 bytes.
