- Co-owners.
  - New routine: &update_coowners() will adjust co-owners new owner used to
    be a co-owner.
    - If this is an official course, and auto-assignment of co-owners is

Calls to routines from londropadd replaced with calls to the same routines in lonuserutils.

- Use lonnet::coursedescription() to extract cnum from cid instead of splitting on underscore.

Bug 5191.  Decouple storage of last access time for a course in nohist_courseids.db from storage of course information.
- Retain backwards compatibility with legacy lonnet::courseiddump()

Other general change: uniform use of 'inst_code' as key in frozen hash instead of 'instcode'.

lond
&put_course_id_handler()
- last access stored in escaped lasttime:courseid key = value hash item
  if legacy lonnet::courseiddump() updates courseinfo.
&put_course_id_hash_handler()
- additional argument - $mode ('timeonly', 'notime' or 'all')
  - determines whether last access, or courseinfo (description,inst_code,owner,type) or both are stored
&dump_course_id_handler()
- documentation updated
- style (replacing unless)
- change location of unescaping when checking filters so double escaping no longer needed for courseinfo stored in frozen hash
- return courseinfo in hash form, if requested as hash, when record has yet to be converted to a frozen hash
&validate_class_access_handler()
- eliminate extra unescaping of $ownerlist

lonnet.pm
&flushcourselogs() includes 'timeonly' argument in call to courseidput().
&courseidput() - if in 'timeonly' mode only courseids are sent to lond in courseidputhash call.
&createcourse()
- courseinfo values in hash no longer escaped (freeze_hash handles this)
- call to flushcourselogs() replaced by call to courseidput()

lonmodifycourse.pm
- courseinfo values in hash no longer escaped
- call to courseidput() includes 'notime' as fourth arg.

coursecatalog.pm
- remove unneeded code, since entry for each course in %courses hash will now be a hash ref.

courseclassifier.pm
- remove unneeded code, since entry for each course in %courses hash will now be a hash ref.

lonpickcourse.pm
- Entry for each course in %courses hash should be a hash ref, when constructing for onlyown courses case.
- instcode to inst_code
- no need to unescape courseinfo value (thaw_hash in lonnet::courseiddump does it)

lonparmset.pm
- call to flushcourselogs() replaced by call to courseidput() after updating course description.
- appenv user's session with new course description.

Store data in nohist_courseids.db as a hash.  Maintain backwards compatibility with writes to the db from legacy lonnet.pm, and also reads from the db from legacy lonnet.pm.

Start towards inclusion of co-owners as well as a single owner, for the purposes of verifying access to official classlist data.

lond
- &put_course_id_hash_handler() added to handle storage of data in nohist_courseids.db as a frozen hash.
- &put_course_id_handler() will add to an existing hash if update is from a legacy lonnet which supplies : separated data.
- &dump_course_id_handler() $as_hash flag extracted from tail. If set, data are returned as a hash.
- validate_class_access_handler() will extract comma-separated owner and co-owners from ownerlist passed to it, and send array ref to localenroll::check_section() to determine if at least one on the owners is authorized to view classlist list data for the institutional section.

lonnet.pm
- storage of hash via call to courseidputhash in lond.  If command is unrecognized on the lond side, subset of the data sent as : separated values
- retrieval of data from nohist_courseids.db - additional $as_hash argument included in courseiddump call to indicate that data should be returned as a frozen hash.
- auto_validate_class_sec() - if third argument is an array ref, then an owner list is built from the supplied owners and co-owners.
- lasttime set on lonnet side (FIXME) - to be changed to lond side.

lomodifycourse.pm
- updated course settings sent as a ref to a hash to lonnet::courseidput()
- include LC_error in span for error messages
- eliminate duplicate error message
- display error if storage of changes fails
- form name corrected to cmod.

coursecatalog.pm
- eliminate unused arg from call to courseclassifier::retrieve_instcodes
- display owner and co-owners (sort by lastname)
- institutional section access for multiple owners

courseclassifier.pm
- course codes from course data if hash, or if : separated string.

lonpickcourse.pm
- course info extracted from hash
- owner info displayed in a list if owner and co-owners exist.

Only allow selection of default authentication method used for auto-enrollment in a course from types available to Domain Coordinator (set in domain config).

- eliminating the domain hash globals in favor of functional access

Prevent stripping of trailing null fields in split() by setting limit to -1.

Undesired stripping of trailing null fields had caused extra : separators to be written in values in nohist_courseids.db between type entry and final entry (last access), in some cases where there was no course owner.  Set numcurrent to a maximum to eliminate the extra items the next time put_course_id_handler() runs to update the entry for a particular courseID.

Include type in courseidput when modify_course() results in change in course owner or institutional code.

Typo (sectionums should be sectionnums).

Set default $type to 'Course', in case the version of lonpickcourse.pm being used has no Course/Non-standard course selector.

Selection of course to be modified now uses routines from lonpickcourse.

Added ability to set course groups portfolio files quota.

Separated display of all current auto-enrollment settings for course from page for setting the four DC-only modifiable settings.

Replaced existing breadcrumbs with standard LON-CAPA breadcrumbs.

Use standard LON-CAPA data table functions.

Some reorganization into subroutines.

- xhtml

Bug 4813.  Retain backwards compatibility with legacy courses in which only a course owner's username is stored in environment.internal.courseowner, and in the course's record in nohist_courseids.db.  New courses will include username:domain (escaped) in nohist_courseids.db.  MCRS can be used to update legacy course owner information (just click "Modify Settings" button, it will be necessary to select the correct course owner where the course domain is different from the owner's domain.

&Apache::lonnet::unescape -> &unescape
&Apache::lonnet::escape -> &escape

-start_page
-eliminate calls to bodytag in favor of start_page
- elimintate call to xmlbegin

- page genearizlzation

- add a space so long lists wrap

- eliminate some overuse of $1

- adding version string and 'purpose of file' line

Moved check_user_status() from Enrollment.pm to loncommon.pm.  Now returns: active, previous or future (instead of ok or expired)

Add extra argument to pass to courseiddump for LON-CAPA courseID (as required by /lonnet/perl/lonnet.pm rev. 1.622).

Bug 3912.  DCs can use courseID (e.g., 257472759ae4061msul1) as a filter when using pickcourse.

- ENV -> env

- <html> -> &Apache::lonxml::xmlbegin, thus valid doctypes are now getting output, Yeah! StandardsCmpliance

- backing out the encoding changes for now

- some xhtml cleanups
- one icon -> lonhttpd

Adding storage of course owner to nohist_courseids.db.  Pick course can permits use of institutional code and/or username of course owner as filters.

localenroll no longer used directly.  Domain to check is domain for DC role, not home domain of user.

Domain should be domain of current DC's role instead of user's home domain.

Bug #3212 Permit lower case Kerberos domain names.

Include institutional course code in nohist_courseids.db.
Format of entries in nohist_courseids.db now -
course_id = description:institutional code:last activity
both (keys and values are escaped).
lonnet::courseiddump now returns escaped values in hash (keys are unescaped),
to preserve the : separator between description and institutional code.

Calls to functions in localenroll.pm mediated by lonc/lond now include domain
in the set of passed parameters to support domain-specific variants in a single
localenroll.pm file housed on a multi-domain library server.

Automated enrollment now sets first access and last access dates for student
roles based on defaults set on course creation, and modifiable via a number
of mechanisms in the Enrollment Manager, and Automated Enrollment Manager.

The Automated Enrollment Manager now provides a utility to allow enrollment type
to be toggled between 'auto' and 'manual', so that students added via CSV file
or singly can become liable for automated update (dropping, section switching
etc.).

Fix bug #3062

Changes to support autoenroll calls from a remote server.

lond on the homeserver for the course(s) handles requests from the remote
server for institutional data (e.g., classlists, valid institutional courseIDs,
institutional section numbers for a course code, validation of course owners), by
calling the appropriate functions in the homeserver's localenroll.pm

All replies are made directly with the exception of fetch_enrollment_query, which
is shipped over to lonsql, in case retrieval of institutional classlists is a
protracted process.

lonsql on the homeserver for the course(s) calls localenroll::fetch_enrollment()
and writes XML files of enrollment data to /home/httpd/perl/tmp

Transfer of classlist data occurs later following an autoretrieve call from the
remote server. It is planned to generalize this function and add encryption to the transfer back to the client.

Autoenroll.pl called by cron on a library server, now only carries out updates for
courses in its domain, for which the library server is the course's homeserver. If a domain has multiple library servers Autoenroll.pl will need to be run on each library server.

Fix a bug and an indent

Eliminate senseless array stuffing in &check_course().  Correct indents.

Added course owner validation for cases where course owner is changed, but course code is unchanged.

Added sanity checking for valid LON-CAPA course ID.

Completed localization. Some changes to menu layout.

For use by domain coordinators to change course code, course owner, default authentication mechanism in any course in the domain.  All of these parameters are used by the automated enrollment process.
