    resources moved to lonacc.pm to facilitate re-use.
- Detect if syllabus template replaced with uploaded PDF or link to external
  PDF file, and send as arg in call to lonwrapper.pm, to circumvent lack of
  scrolling for multi-page PDFs in iframes on iOS.

- For public user (e.g., unauthenticated user viewing syllabus etc.)
  set $r->user() to public:public, just in case there a username of
  "public" is a real institutional username (and SSO is in use).
- Prevent public user being identified as SSO-authenticated user without
  LON-CAPA username.

- SSO authenticated user without existing LON-CAPA account:
  Handle as SSO user if either lonSSOUserUnknownRedirect is defined or
  domain configuration permits self-creation of LC account by sso user.

- Change to address bug 6587 in lonacc.pm (rev. 1.139) was causing uploaded
  xlsx files to include an extra byte (line feed), which would cause

  domain is not server's default domain) for URLs requiring "valid-user",
- Apache access logs will now include 'public' as requester for image
  files from /res/adm/pages and also domain logos etc.

- remove trailing whitespace.

- Support Apache 2.4 (Fedora 18, 19, 20; SuSE 13.1)
  - $r->user needs to be set in lonnet::check_for_valid_session()
    if the session is valid, but lonacc:sso_login() also needs to be able
    to identify an SSO case.

- Modify POD to eliminate errors seen with pod2man in perl 5.18

- Bug 6675
- Case where $env{'REMOTE_ADDR'} as reported to server selected to host
  user session, is different from $env{'REMOTE_ADDR'} as reported to
  server which handled original authentication request.

    (ii) Session will be hosted on offload server
    for each of (a) SSO users from load balancer's domain, (b) non-SSO users
  - Setting to host on load balancer will be ignored if switch server was called
    by an author or co-author switching to server housing the authoring space.

- Bug 5962.
  Additional syllabus option - minimal template (provides a "blank" HTML
  file (portfolio/syllabus/loncapa.html) which can be edited using the
  WYSIWYG editor.
- Edit button for uploaded syllabus file (html) and minimal template
  provides direct access to WYSIWYG editing screen.

- Apache 2.4 requires $r->user() to be set, if "Require valid-user" applies to
  the requested page, otherwise there is an error:

  was called via internal_redirect, immediately following authentication.

- Supplemental Content area can contain Syllabus and/or Personal Information pages.
- Do not append symb (if either item is also used in Main content area), if
  accessed via Supplemental Content.

  - More granularity available in load balancing:
     - Rules can be defined for users in domain, based on institutional
       affiliation (e.g., Faculty, Staff, Student etc.).
     - Rules for advanced user or author trump rules based on affiliation
     - Rules can also be set for users from other domain hosted by
       institution (i.e., multi-domain server set-ups)
     - Rules can also be set for users from other institutions.

- Additional perlVar for sso_login.
  lonSSOUserDomain - LON-CAPA domain for users logging in via SSO
                     (could be different to default domain of server).

    switchserver offloads session.

- Bug 3987. Deep-linking.
- Preserve role and symb from query string in call to SSO authenticator.
  - Propagate to migrateuser when starting session.

- 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.

- Backport 1.124.

- Skip cookie check for icons etc. in /res/adm/pages

- Backport 1.118, 1.122

Bugs 5719 and 5820.
- Do not add contents of files uploaded to essayresponse items in course activity log.
- Round file size (in Mb) to 6 decimal places when setting HWFILESIZE form element.
- HWFILESIZE and HWFILETOOBIG (if set) will be stored in course activity log.

POD documentation changes

Reformatted POD, moved to bottom of file

Added/updated/converted POD. Many files had their POD redone to new standards.

Bug 5719 Size limits for File Upload in Essay response.
 - Max. cumulative size for submitted files applies to total for all files submitted to a particular essayresponse item. Default is 100 MB.
 - In course context, &lonacc:get_posted_cgi() will now no longer add file contents to %env if size exceeds max. for item.
 - Additional checks in essayresponse::file_submission() will assign award as "EXCESS_FILESIZE" if total of all files being submitted for sinle essayresponse item exceed max set via
PARM.
 - Modification to $Apache::lonhomework::results{"resource.$part.$id.$which"} to now include a comma separated list of only those submitted files which passed both the filetype and size tests.

POD documentation changes

- Incoming users authenticated by SSO may not always need to go to the roles screen.
- Add the following to a <Location $url> directive in loncapa_apache_conf:
PerlSetVar      ssodirecturl 1
for authenticated SSO users to go to $url after session initialization.

- If a user successfully authenticates via SSO, but a LON-CAPA account is lacking for the username used to authenticate, offer the possibility of creating an account, if selfcreation is allowed for the 'sso' auth type.
- selfcreation auth types are now stored as an array, instead of a single-valued scalar.

- &get_posted_cgi() can take second (optional) argument - a reference to an array of the names of form elements which may be retrieved from a submitted form (method was "post").

- backport 1.112, 1.113

- boundary value is announced in the content-type so use it there rather
  than trying to self discover it

- safari 3 uses + in the content separator lines

- convert exisiting cookie reads/validations to use
   lonnet::check_for_valid_session

	Put separator between $uname and $udom

	Add access info for multidownload of student submissions.

Put reg exp check for domain logo in lonnet  - &is_domainimage()
checkauthen, publiccheck and lonacc all need this to serve images for log-in page if port 8080 is not in use.
Other possibilities - (1) call once in checkauthen and pass along to publiccheck and lonacc in Apache notes, or (2) modify loncapa_apach.conf.
lonhttpd to use a call to the same routine.

- log sso authorizations users

Look for lonSSOReloginServer set in an apache conf file (e.g., sentinel.conf at MSU), so the "login again" link displayed on logout points to a SSO-enabled server if the user's login was originally SSO-authenticated.

If SSO auth, need to set $env{'request.sso.login'} = 1 before internal_redirect to switchserver.

If SSO user is authenticated but has no LON-CAPA account provide information, including results of query of RO's LONCAPA_ClassList table for the user.

Some routines in coursecatalog modified to support use by sentinelonly.pm

Add response code of 'B' to lonnet::allowed() to indicate access to a file is currently subject to a block, because the file owner is part of a course with active communications blocking, and file viewer does not have 'evb' privilege in the course to nullify the block.

Used to block access to portfolio files.  Response of 'B' triggers blockedaccess.pm which displays information about blocking conditions.

     (thus no longer getting two ids consumed)
   - pucliccheck will initlaize the env of a puclic user so
     lonacc can use the existance of user.name and user.domain being
     set as a valid check of a being a valid user (as opposed to the
     cookie being set to a valid file)

- allowing public access to aboutme/portfolio

Mechanism for user to provide passphrase, and for the server to validate it when user attempts to access a passphrase-protected portfolio file.

grppg replaces with smppg for group homepages.  Context determined from course domain and course number in URL.

Fixes so more menu buttons are provided when group page is accessed via Navigation controls (i.e., as a registered resource).  Other changes so grppg behaves like smppg.

- upload group file publixc access wasn't working BUG#4881

Portfolio file access control now allows for domain-based, user-based, and course/group-based controls.  Passphrase-protected access (without login) yet to be enabled.

Enable users to set access controls on portfolio files to permit public viewing. Third iteration of data structure in file_permissions.db for storage of access contol records. Now uses key = value for individual access control records and a key = anonymous hash for fast look-ups of all records for a single file.   Use of a temporary lock record to prevent others modifying access control records for a specific portfolio file while the record for the same file is being updated. Additional argument added to call to lonhtmlcommon::datesetter() to optionally suppress display of calendar link.

- preserve the fact that we ssoed in

- touchups from the loncommon move

- moving get_posted_cgi from loncommon to lonacc

- moving hadnler routines out of lonnet into lonacc

- start_page

correct syntax.

- /adm/coursedocs/showdoc/ resources have fully valid sy,mbs now

Let browser determine what language to use in public access, rather than
whatever language was last used in a specific child process.

- changes needed to support making loacc a authz handler
- add ability 'lonBalancer' to force all sesions to be offloaded

Remove "already logged in" and "no active roles" weirdness after looking
at /public-resources.

- need to use lonacc when accessing .hlp files to get session env, but need to also allow public access to help files

- restrict public users to /res/* and /adm/roles, /adm/logout, and /adm/randomlabel.png

- BUG#2573 can't do randomlabel/imageresponse/reactionresponse/organicresponse etc as 'public' resources,
   - public users on first access get a Cookie and a skeleton of a session environment now

- should use decode_symb instead

- ENV -> env

- the _symb.db now actually does store symbs
- I am pretty sure the symbread changes are correct, but I still need to double check them

- nsdl branch needs and fixes

- a BAD_REQUEST resposne is not very helpful, why not just throw up the login page.

- part of BUG#3904, remote navigating a resource not in the course doesn't gie you a return location link

- public homework access was broken because we switched homework forms to 'multipart/form-data' but public acces wasn't using the get_posted_cgi to parse the form data

- setup the browser.* attributes for public users

- one more thing, if they didn't give a symb, and we don't have a symb, we can't verify it at this stage, this can happen we things are ambiguous, so pass them by for now and we'll disambiguiate later

- only things on a mpa shoul dhave a symb check done BUG#3766

- /res/adm things don't have symbs

- more of BUG#3714

- remove log spew

- allow smpedit to take a symb arg

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.

- Somewhat amazed at how easy this was should with these changes
   - uploaded .html/.page (all ssi type docs) now
       - get parsed
       - can be printed
       - get default parameters
       - are no longer wrapper ed

- .problems are still somewhat issue oriented though (need real metadata support for uploaded)

- decode_symb()

Do not explicitly request most recent versions of files.

Two subroutines will need caching:

* lonnet::fixversion
& lonnet::getversion

Setting content language in headers.

Initialize language handle

Consolidate functions from access control handlers in order to eventually
add them also to lonuploadedacc.pm - preparation for running uploaded
problems.

- Perl 5.80 + mod_perl 2.0 + APache 2.0  really want the 0 in there

For the reload button on the inline remote to work, "last_known" in symblist
must be set correctly.

Install new managekeys handler, make new permission "mky" to invoke it

- public users can now submit answers to problems that are published public
- lonxml includes line numbers when complaing about missing tags

Handle login without Remote.

Direct notification email directly to login screen.

Still working on running syllabus, etc, without /adm/wrapper.

best wishes to all.

- fixes BUG#300
- now log all print accesses
- now force restrictions on acces to files in prtspool

Bug #773

Recognizes "/public" as "public"

Bug 573.
Only calls login screen for resources with embstyle ssi, or /adm/roles,
or /adm/logout

Bug 488
Undo version 1.32 of lonacc to avoid unneccessary calls to metadata.
Postpone to lonnet::allowed call.
Deal with 'priv' while we are at it.

Add copyright to request environment (toward bug 488)

This is incorporating the &symbverify call for user-supplied symbs.
Towards bug 279. Should bring up roles error when wrong.

Should register symb correctly when directly jumping to GET provided symb

Accepts symb now

- use the new add_to_env command in loncommon, this way <select multiple> will work

Hopefully (POST only) accepts <select multiple>

Store request method

adding in POD documentation; using loncommon::fileembstyle instead of
lonnet -Scott Harrison

Counts accesses to resources

Logging of accesses and caching of symb

GPL

Public Access

<allow> more powerful, has wildcards - needs TESTING!!!

Wildcards in httprefs

Bugfix

Request State more Informative

Applied shared flocks on the environment

Remove newlines at the end of non-file form fields

Now take "multipart/form-data" forms for file upload

No "wild guesses" based on directory, use <allow> tag instead

Tries to figure out referer a little harder to work with subrequests from
Java applets

Info for lonnet::allowed added early into the request cycle

Now also unescape form element name

Direct writing to environment

Flush content length after reading POST parms

Access control course level

Updates. Implement roles control on browsing and menu.

Roles have starting and end time
Bug fixes after replication shift
New login screen
Authenticator routes to roles screen
Form variables are transfered to environment (not tested)

removed "profile."
added request.filename to enviroment

Limit length of $middlename to 16 characters for critical message buffer
Add appenv to lonnet (not tested yet)

Putting environment variables into session profile
Reading environment variables from session profile
Not tested yet
