Localization:
- Corrected &mt() update lonroles.pm 1.234: Allow change of parameter order due to localization but keep proper HTML structure.
- Wording correction on roles screen (no roles): It's actually the right to _request_ creation of courses/communities, not the right to create them

- Removed unnecessary table
- Corrected &mt usage (don't translate twice)

- Usability improvements.
- Reduce need for user to complete logout/login cycle to be able to select roles with 'will' role status (roles with future access which existed at time of last log-in, and are "active"):
  - Display of roles screen causes privs to propagate to %env in the background and become selectable.
  - &gather_roles() routine created (ongoing simplification of monolithic handler() routine).
  - &Apache::lonnet::roles_status() takes new arg ($refresh).
  - New environment variable: user.refresh.time - records when last check was made for 'will' type role.

XHTML:
- Properly exclude javascript code from being interpreted as HTML code

  - Add header to upload table (until such time as breadcrumbs are updated for grades.pm).

- HTML documents uploaded directly to a course can be edited by a Course Coordinator (mdc priv).
- "Edit this resource" link displayed in inline menu.
- Link will switch server to course's home server if session is currently hoosted elsewehere (unless a lock is in place).

- Deep linking:
  - origurl and symb args can be included in query string for switchserver call, so switched session will go to the same resource on the new server.

Work in progress.
Logging needed: changes, and by whom.

Bug 5842.
 - "Edit this resource" link is displayed in inline menu if user is a DC in domain of resource author, and author has not blocked DC access to CSTR.
 - request for /priv/$author sets ad hoc co-author privs for user (if no existing privs) if user is a DC in author's CSTR, and if DC access is not blocked by author's user prefs.

&check_privs(), &set_privileges(), and &role_status() moved from lonroles.pm to lonnet.pm -- first two renamed as: check_adhoc_privs(), set_adhoc_privileges().

&is_active_dc() added to loncacc.pm to check if user has active DC role in resource author's domain.

Box title is now the main title of the next page and the link text or the former page title will be set to the subtitle in the near future.
Group: consistent wording

- &queued_selfenrollment() generates a table of a user's self-enrollment requests currently pending approval by Course Coordinators in the respective courses.

- Backport 1.215.

- Bug 5792.
- Timezones used in start and end dates on roles screen are specific to the role (appropriate course time zone for course roles, otherwise domain default for other roles based on role's domain).

- $brcrum is a reference to an anonymous array [] (use $brcrum not @brcrum).
- add sanity checking to confirm that the arg passed was an array ref.
- style
  - indentation
  - exists()

Added Breadcrumbs in Sites that dose not have any
Added a parameter bread_crumbs to the start_page function, so it can handel the creation of breadcrumbs

Standard styles for roles screen
and some other optimizations

lonroles.pm:
- Use data_table for roles screen
- Moved status color from whole row background to only the first column.
  (This change is meant as an intermediate suggestion to get rid of the "color shock" effect ("Everything's green here!") and usage of standard LON-CAPA styles by keeping the main functionality)
-  Only the green background for active, unselected roles isn't used anymore. (No special indication needed)
- Removed some hardcoded font styles
- Removed the usage of different font colors (not needed anymore; -> $tfont)
- Removed empty separator rows (separation now done by different background colors in the data table rows)
- Replaced hardcoded color styles with new external styles (->  $tbg)
- Use double quotes for html attributes
- Added missing &mt() call (-> Current Privileges)

loncommon.pm:
- Removed unneeded and unused rolesmenu styles
- Added new styles for status display on roles screen but keep already used color values (-> lonroles.pm)
- Don't change background color counter for standard rows anymore, if empty_row is called and displayed
- Removed now unused font parameter from syllabuswrapper

Removed font tags replaced by span tags

Added/modified POD documentation

- "Re-initialize" button in roles screen no longer restricted to advanced users.
- Show appropriate message on roles screen when navmap object could not be created because inactivity caused deletion of $user_$course.db and/or $user_$course_params.db from lonDaemns/tmp directory.

- Ad hoc role for CC needs to set privs for any groups to which the CC belongs when selecting other roles in the course.

Do not automatically select the only available role

Bug 5779 (introduced in 1.183 -- work on bug 3765):
- If user was a DC in at least one domain, but was not a DC in the domain to which the CA role belonged, the assigned CA role could not be selected.
- Fix is to check if DC actually has the CA role active in user roles in %env, before checking for DC status in the domain to which the CA belongs.  If so, check if switchserver is needed.

- Also check if requested CA role is actually for author space of current user - if so, set role request to AU instead of CA (CA in the user's own CSTR doesn't make sense).

- Do not block CA role access if user has been assigned a CA role, (was occurring if user is also a DC, and author blocked ad hoc access by DCs).

Localization:
- Added missing &mt() calls
- Optimized &mt() calls

- For bug 3987.  lonroles.pm will accept a destsymb form item, encode it and append it to the destinationurl.
- Intended to support linking to a specific resource in a course from outside LON-CAPA.
- Login page and SSO need to preserve an appropriate query string for the call to /adm/roles after authentication and session initialization.

- If user has only one active role do not show "Select a Course to Enter" header line.
- If user has only one active role do not show "No role specified" line, since automatic role selection for users with a single role means role type "cm" is inaccessible.
- If user has a single active role, and that role is au, ca or aa, only do automatic role selection if user's session is on home server for corresponding author; display a switch server link if not (we don't automatically switch in case the home server is overloaded and we could get into an infinite loop of switching/offloading).

- use showdom in coursecatalog query string to default to display of the course catalog for an appropriate domain.
- eliminate duplicate declaration ($cdom, $cnum).

- Use &Apache::lonnet::auto_run() to check if auto-enrollment is active for the user's domain to replace &check_autoenroll() which is no longer needed.

- Correction to match for valid custom role for CC needing an ad hoc in a course.

- role is in $env{'form.switchrole'} when CC is switching into a role in course context
- correction to regexp to extract section from adhoc role.

- Link to course catalog on roles screen for advanced users.

- Display a course catalog link at the top of the roles screen, with advice on self-enrollment, for users without advanced roles, and at least one active role.

Localized version number info on roles screen

No course restrictions.

- Domain Coordinator selection of ad hoc co-author role.
  - "Select Author" link triggers pop-up window with display of authors in domain.
  - Selection of author from list causes roles page to auto-submit.
  - Eliminated distinction between "new" ad hoc CA role and previously selected one.
  - Added redirection to switchserver, if current session is not on homeserver of selected author (needs testing).

- More compact display for ad hoc roles available to a DC
- Fix some unbalanced <tr> tags in Recent roles rows.
- Fix some xhtml - ordering of </span></font>, <input /> etc. (incomplete - font color="" needs to be from css).
Work in progress.

- If user has no active roles, now display any future roles, and a link to the course catalog.
- if automated enrollment is in use in the user's domain, display a message about     reasons why enrollment might not have occurred so far.
- moved some code from handler() into subroutines - roletable_headers(), print_rolerows() and roletypes().

Bug #5613 - user can opt out of DC access

More work on 5613

Locking

- backport 1.187

- backport 1.184

Localization:
Added missing &mt() to Access Control screen

Change arguments accepted by lonnet::appenv() to:
1. reference to hash
2. (optional) reference to array.

Change all instances where lonnet::appenv() is called to replace first argument passed (originally a hash) to a reference to the hash.

- Modify lonnet.pm rev 1.35 code intended to prevent "dangerous" modifications of the environment, so it will actually do this.
- Allow these modifications to be made in certain instances:
   DC switching to adhoc role
   CC switching to a different course role in the current course.
   user self-enrolling as a student

- Improving ease of use (cf. Moodle).

Inline navigation includes dropdown to change to a different role in the course.
Course Coordinator - can switch to any role currently used in the course.
Other users - can switch to any other course roles assigned to them.

Work in progress.
- Needs additional dropdown for section context.
- Needs to maintain display of encrypted URLs as unencrypted when switching into CC role.

- Typo and some localization for alert messages.

Don't go to non-exising authorspaces

Bug #3765: Ad-hoc co-author

- BUG#5516 - TA's aren't ADV but should trigger the wording change from Course -> role

Bug 2593 csv file upload by DC to change passwords
- DCs can change authentication, add a domain or course role for uploaded users, and/or change user information (names, ID, e-mail address etc.)
- Authors can add co-authors
- Course Coordinators can add course roles.
- Some subroutines in londropdd.pm moved to lonuserutils.pm.  Some routines in loncreateuser.pm moved to lonuserutils.pm
- &process_pick() moved from lonroles.pm to lonpickcourse.pm
- Work in progress.  Ultimate goal is to provide user listing functionality in different contexts and eliminate separate ENRL button.

With SSO enabled, it is possible to log-in and reach the roles screen with Javascript disabled.
- provide a warning
- for users with a single active role, provide a "Continue" button.
- xhtml

Not needed anymore after Switchserver

* increase character contrast by default (white background)

- backport 1.163

People do not always see the Roles page first, and or don't expect the general
access to the help system on that page.

- hide course type idea from 2.2

- why be generic when we can be specific

- help_open_menu morph

- 'user roles' isn't a real function

- extend plaintext to handle cr roles
- lonroles makes use of the improved plaintext
- from mlucas

- BUG#3763 - reqork role freezing functionality

- fixes to discussion group &mt()
- switch to course_type accessor
- switch to <span class="LC_error">

- typo

- and unless conversion that was incorrect

-make use of new hash interface

Conversion of role names now occurs in lonnet::plaintext().  If rolename is set for a specific role in the course environment this is used, otherwise defaults to name defined in rolesplain.tab.  rolesplain.tab can now contain multiple entries (: separated) - which one is used depends on course type. loncommon::course_type() is accesssor function added to provide type; loncommon::convert_role() eliminated.  loncommon::bodytag() now includes $realm information for co-author role.

Adding ANGEL-style groups as a thin veneer. Roles in Discussion groups are separated from roles in Courses.

Bug #1223: error when first resource is hidden
Also: error when first resource is encrypted

Bug #4370: better warning if there are errors during course initialization,
e.g., a map included more than once.

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

- BUG#3254 - remote wasn't getting start when doing 'Switch Server'

- start_page

DC's assumption of any CC role.  Improve readibility by replacing $1 and $2 in calls to &set_privileges with $domain and $coursenum.  Correct the setting of $env{request.role} to cc./$cdom/$cnum (instead of just cc).

- check whn for both course and course+section

- switch to using ::get

- backport 1.143

- fix author role so switch server works for author too

Add whn privilege to make what's new available to cc, in, ta and custom role. Display NEW button for users with this privilege in a course.
CeS: ----------------------------------------------------------------------

- death to user.adv

typo

Display of whatsnew page on entering a course can be set for specific courses (override user prefs).  Can suppress count of unread posts per resource. Link to first resource at top of page not shown if NEW button used to get to whatsnew. What's new no longer restricted to CC role - accessible to adavnced roles in a course.

DC's "Select Course" link to become a CC in a course in the domain now works for regular link in "Domain" as well as link in "Recent Roles".

Adding link to Groups in inline menu, adding GRPS button, adding request.course.groups to %env to allow easy access to a user's active groups.

Don't include course group affiliations in selectable roles.

In some tralslations the Pleasestandby ends up with a newline in it.

Trying to catch if Role is initialized twice in a row

- CC role secltor comes along with the DC role into recent roles

- the roles screen got some reorg to increase the space avaible for remarks, and to better associate the DC role with the associated line for the CC in any course line.

- xhtmlize

- 'switch server' now really does

- a desire for Domain to trump other roles

- missed one bit for making sure the whatsnew page appears when it should with external nav screen

- taking out the highlighting code
- recentering the 'realm' dividers

Back in town.

Bug #4135: underprivileged "assistant co-author"
Part of Bug #1900: CUSR shows up for authors again

- course init helper should defeat what'snew (Bug# 4132)

Syntax error

Default is now to display "What's New?" screen to Course Coordinators, unless they have set preference to go to start of course, whenever a course is accessed from roles screen.

- bug #3193, column 3 is a bit spurious

- trying to be moe helpful in access control problem cases, throw up the 're-init course' button if the get the access control message and have modified the course with reinit (Kinda BUG# 3646)

- BG#3985, the adv permissions didn;t have an effect in cases where it depended on athe course id

- xhtml cleaning

BUG#3736

If displaying 'Recent Roles', show header for other role type.

Eliminate display of "Recent courses visited by DC" - use Recent Roles instead. Recent roles display will now retrieve role info for recently visited CC roles created on the fly for a DC, if not yet visited this session.

DC selection of CC role from all courses in a particular domain modified to work when user is DC in more than one domain. No longer duplicate javascript functions in allcourses_row().

- Mark Lucas's changes to fix BUG#2078

Recent roles display for DC now gathers info for CC roles not viewed this session, but in recently viewed list.  Change in db name for recent roles.  Keys n db now: user.role.cc.\$dom\$course etc.  Ready for generalization to display of recent roles for all users.

Users with multiple DC roles can now select a CC role from any of the domains in which they are DC. Extra click eliminated -- selection in Pickcourse window loads CC role in opener window.

DC selection of CC roles.  Intermediate page eliminated.  Ordering of roles reverted to original order as per v 1.103.  Recent courses visited by DC now displayed at top of roles page. "Select Course" link for DC to go to open pickcourse window now displayed on main roles page.

CC privs created on the fly as needed for DC.  Works nicely now.

DC can select a CC role in his/her domain, and receive CC privileges on the fly.  Work in progress. Access is not quite set right for pages.

Changes made during a house call by the style police

Suppress display of CC roles in a domain in which the user is a DC.  Allow the DC to select from recently visited CC roles in the domain, or select a course via lonpickcourse.

Consolidation + correction to role_status subroutine.

Consolidating repeated code into subroutine.

- make adv a real role priv

- don't &mt the role text it's already &mt
- when changing roels delete the user.state

- adding more 'Continue' links
