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.

Fixed bug for problem library version 2 - now it can select problems from
all sections, or all chapters and all sections, etc.

Revision 3412 - Directory Listing

More changes for problem library version 2.

Changes for problem library version 2 to support recent change to setmaker.

Update to support version 2 of the ProblemLibrary.

Revision 3404 - Directory Listing
Modified Tue Jul 26 17:35:54 2005 UTC (7 years, 10 months ago) by jj

Lots of indentation fixup, and started adding code for new and improved
problem library.  Still compatible with current "Problem Library".

Revision 3377 - Directory Listing
Modified Thu Jul 14 13:15:27 2005 UTC (7 years, 10 months ago) by glarose

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.

Revision 3290 - Directory Listing
Modified Wed Jun 15 21:46:12 2005 UTC (7 years, 11 months ago) by jj

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.

Modified Fri May 20 16:27:43 2005 UTC (8 years ago) by gage

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.

Revision 3059 - Directory Listing
Modified Tue Dec 21 04:41:03 2004 UTC (8 years, 5 months ago) by sh002i

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

Revision 2835 - Directory Listing
Modified Mon Sep 27 19:21:54 2004 UTC (8 years, 7 months ago) by sh002i

added dbLayoutSQLSources function to get a hash mapping DBI sources to
the username and password of the source and the tables that use the
source.

Revision 2777 - Directory Listing
Modified Mon Sep 13 19:34:54 2004 UTC (8 years, 8 months ago) by sh002i

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.

Revision 2766 - Directory Listing
Modified Fri Sep 10 22:15:51 2004 UTC (8 years, 8 months ago) by sh002i

Revision 2450 - Directory Listing
Modified Wed Jul 7 14:37:32 2004 UTC (8 years, 10 months ago) by gage

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

This addresses some of the concerns in bug #556

Revision 2255 - Directory Listing
Modified Sat Jun 5 19:20:13 2004 UTC (8 years, 11 months ago) by gage

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.

Revision 2235 - Directory Listing
Modified Mon May 31 16:49:04 2004 UTC (8 years, 11 months ago) by jj

Allow optional argument of the set (which better be real).

Revision 2234 - Directory Listing
Modified Mon May 31 16:35:00 2004 UTC (8 years, 11 months ago) by jj

Added support for initial problem number to renderProblems, and better support for controlling the problem seed.

Revision 2228 - Directory Listing
Modified Sun May 30 02:35:06 2004 UTC (8 years, 11 months ago) by jj

Make the message blank when the user doesn't want problems rendered.  Different modules may want different messages anyway.

Revision 2224 - Directory Listing
Modified Fri May 28 23:13:14 2004 UTC (8 years, 11 months ago) by jj

Changed interface to renderProblems to be key=>value pairs to make it easier to extend options.  New option is displayMode, which is allowed to be 'None' if you don't really want the problems rendered.

when given invalid table names.

Revision 1993 - Directory Listing
Modified Mon May 3 20:44:24 2004 UTC (9 years ago) by jj

Initial import.  This may not be the right destination, especially as its
database methods become more integrated with the ones already in WeBWorK.

Revision 1988 - Directory Listing

Initial import.  Lets you render a problem which is not part of anything.

Revision 1921 - Directory Listing
Modified Tue Mar 23 04:20:56 2004 UTC (9 years, 2 months ago) by sh002i

added programmatic format support

Revision 1823 - Directory Listing
Added Mon Mar 1 00:49:25 2004 UTC (9 years, 2 months ago) by sh002i

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.
