Before this change if a new post was made after the digest time but
before todays daily digest had been sent the run time on the digest
would be set to the next day resulting in no digest being sent to
the user.
By adding the server midnight to the custom data on the task we
ensure that in this case a new adhoc task is created for the next
day leaving the current one to get processed.
Server midnight is used so that if the digest time setting is
changed we would not get two tasks queued for the same day.
Ideally any new test should be using a class name matching
the file name, and to use namespace when clearly belonging to
a component (sub-namespace also allowed for better accuracy).
And, also, adding a @covers label to indicate which class
(preferred, method is also possible) is being covered with the test.
This also implements the functionality for SCORM packages, which may
have SVG images embedded within their content which require loading
directly (and are only created by users with appropriate risk flag).
Differences can be checked with git diff --ignore-all-space and
that will show that the only non-whitespace change is in a test
in the git lib/tests/html2text_test.php file. In that case the
whitespace has been replaced by a quoted string (of whitespaces)
keeping the test 100% equivalent and workarrounding the whitespace.
For teachers viewing the assignment summary (/mod/assign/index.php),
it shows a '-' in the 'Grade' column. Instead of showing a '-', display
the number of items that need grading.
Augment by creating a link to the grading page so that teachers can see
the outstanding assignments more quickly.
Also attempted to write phpunit tests that verify values for ungraded
submissions for teachers.
This is the 3rd round adding the tags to some scenarios
detected to be failing with zerosize problems lately.
Note that @ MDL-71108, the final solution will happen, say
switching to own webdriver till the upstream one is fixed
or whatever. Our @skip_chrome_zerosize solution is just a
workaround to have all those scenarios detected and ignored
by normal runs.
