The new setting will allow to host the temporary backup files
into a specific target directory. Defaults to '$CFG->tempdir/backup'.
Calling make_backup_temp_directory() checks that the required sub-directory
will be properly created under the new target directory.
Before this patch if the pre-check failed during
the final stage of an import a request for the
page header to be output was made for a second
time, this caused a coding_error to occur.
This change removes the second request to
output the page header, which will allow the user
to see the reasons the pre-check failed.
When doing a backup or restore operation with the normal user interface,
if there is anything in the backup/restore log, it will now be displayed
at the end of the process below the Continue button.
If you have developer debugging enabled, it sets the display level to
LOG_DEBUG and there will always be content in the log. Otherwise, it
uses LOG_INFO which generally means the log is empty, and nothing
displays (no visible change for users).
Unfortunately it isn't possible to display the current stage before
printing header any more, because we need to be able to show a
progress bar while doing the code that considers whether or not
priunt stage. So this change removes stage information from page
title. It is still present (in bold) in the strip that shows where
you are within the restore/import.
This display was inconsistent anyway; change makes it consistent
between Restore and Import.
1. Changes progress bar code to allow headings for progress bar (so users have
some clue what's going on if a page has more than one progress bar).
2. Changes restore code so that a progress bar can display during pre-checks if
they take longer than 5 seconds.
3. Changes pre-check and restore code so that, in various points where the system
can take a long time within an individual step, intederminate progress is
indicated and it won't time out.
The course import now makes use of the backup and restore processed and the backup UI to allow the user to import one course into another.
The new UI is much the same as the backup ui except preceeded by a course selector to choose the course to import from.
