still have to do something about archive/unarchive -- they are not only
mysql specific, but they rely on the database being local, on the
default port, and named "webwork". :P

Added class to protect objects from evil prying problem code.
Uses the closure-as-object technique to protect the self hash of the
underlying object from problem code. All that the problem code sees is a
blessed coderef. The coderef is a closure over the underlying object and
the list of allowed methods. You can invoke the coderef directly, with
the name of the method to invoke as the first argument, but the class
also provides an AUTOLOAD routine that calls the coderef for you, so you
can continue to use the class as usual.

Implemented unarchiving function to complement archiving function.
Archive exports the course database to courseName/DATA and then tas and gzips the directory courseName to
courseDirectory/courseName.tar.gz
Unarchive allows one to choose files of the type courseDirectory/courseName.tar.gz and then
ungzip, untar them to courseDirectory/courseName -- the database record in courseName/DATA is
then loaded into the webwork database.
So far there is only minimal error checking about whether all or part of the course exists when unarchiving.
There are not yet features for archiving and then deleting a course -- these two operations have to be done
separately for now.

modifications necessary to support moodle tables:
* respect non_native flag in dbLayout
* don't attempt to add users if user table is non_native
* rather than checking for the string "sql_single" in renameCourse and
archiveCourse, and erroring out otherwise, we check to see if there is
a copyCourseDataHelper or archiveCourseHelper implementation
(respectively). new getHelperRef subroutine helps with this.
With these changes, courses with the sql_moodle dbLayout can be created,
deleted, renamed, and archived using the WeBWorK course management
tools.

forward-port from rel-2-2-patches: (make addCourse, deleteCourse more
robust.
- pre-check permissions before trying to mkdir/rmtree
- treat creation errors on directories other than the root as warnings
- treat deletion errors on all directories as warnings
- treat sql_single "drop table" errors as warnings
- supress DBI's error reporting for command-line addcourse/delcourse)

after 2000 and some files that were last modified before 2006.)

I've modified the renameCourse code to simply issue a warning when a
course directory (other than the course root dir) is not movable. I've
also added error checking for some of the more common reasons for
directories to not be movable, so that the warning message is more
informative.
Resolves bug #943.
Originally committed to branch rel-2-2-dev.
Forward-ported without modification to HEAD.

Allow snippets of html (or Tex) to be specified in global.conf to be inserted right before/after the body of a problem. A commented out example which produces boxed problem in HTML is given. In this approach, the added parts are not used for problems rendered in the Library Browser or Problem Set Detail.
This addresses bug 817. This solution may not be suitable for inclusion of needed bits for modes such as asciimath or tth because the those bits of html are probably needed for display in the Library Browser. It is hard to distinguish bits which are always wanted, and those which are only wanted for use by Problem.
To make use of this, you need to update your global.conf, and make the corresponding pg update.

Add the beginnings of a facility for archiving a course. This method uses mysqldump
and therefore will work only with a mysql database. Many things are still hardwired
In particular mysqldump is hardwired.
The database name is hardwired to "webwork"
Archiving consists of dumping the tables associated to the course to a file
$courseID/DATA/$courseID_mysql.database (this file can be used
to created a new database for the course. it will not overwrite existing
tables however.)
Then the entire course directory is tarred and gzipped and placed
in the courses directory with the naem $courseID.tar.gz
Currently nothing is deleted from the database and no directories are deleted.
So the implementation is fairly safe, but not yet very useful for course management.
There is not yet a facility for automatically importing the archived course.

Preliminary commit of changes to add Gateway module.
This adds to WeBWorK
- the ability to create versioned, timed problem sets ("gateway tests")
for which all problems are displayed on a single page ("versioned"
means that students can get multiple versions of the problem set),
- the ability to create sets that draw problems from groups of
problems, and
- the ability to create sets that require a proctor login to start
and grade.
Sets can be defined as gateway tests or proctored gateway tests from
the ProblemSetDetail page.
Not quite bug-free yet. Known bugs include handling of problem values
on the Student Progress page (I think this may be a problem with
changing from sql database format where all entries were 'text' to
sql_single in ver 2.1, where they are integer), and a division by zero
error on the grades page (which may be the same problem).
Tests with a number of attempts per version greater than one haven't
been carefully tested, nor has scoring of gateway tests.

This change affects course creation using mysql. Field types are now
determined by DB/Record/*.pm in the function SQL_TYPES. Key fields
which are text are set to binary types (blobs) so that indexing on those
fields is case sensitive. The net result should be fast database access
while still having it be case-sensitive in the searching.

Import and Export now create gzipped files in the template directory
of the admin course. These files can than be downloaded using
the FileManager. The export and import process are still VERY slow, but
at least it no longer matters if your browser times out.

Added course renaming to CourseManagement, CourseAdmin.
It works like this:
- move the course directory
- move any course subdirectories that are still at their old locations
(like if they were outside the course directory)
- create a new database using addCourseHelper()
- copy the course data into the new course database using
copyCourseDataHelper() (INSERT INTO $new SELECT * FROM $old)
- delete the old course database using deleteCourseHelper()
TODO:
* write helpers for gdbm and sql layouts
* write command-line script

disabled "sid_open", "sid_due", and "sid_answer" formats, since they
don't currenly work with timezones.
We need to find some way to get the timezone information in there
without messing up the interface. One option is to actually have the
database system aware of the timezone and propgate that information on
to the Set and UserSet Record classes. Then, add formatted pseudo-fields
to those record classes that encapsulate the date conversions. Hm, that
would be cool.
Eventually, it would be nice if the date accessors returned DateTime
objects instead of epochs, but that is for later.

Changed the misnamed problem_header to hardcopy_header which is a more accurate
description of the variables use.
Hardcopy.pm now consults hardcopy_header as opposed to set_header

If there is an error, other than "course exists" then the directory tree
is cleared. This corrects a behavior in which the creation of the new
course would fail half way through, but the directory tree would remain
-- this made it appear as if the course existed.
-- This fix is still somewhat fragile.

Added utility modules for sorting lists of records and formatting
records as strings (WeBWorK::Utils::SortRecords and ::FormatRecords,
respectively).
These modules are important because they not only know how to sort or
format records, they can also be queried for a list of sorts or formats
suitable for display, i.e. in popup menus near the list of records.
These modules are being used as the basis for a module which
encapsulates a "record list" widget.
