to <br /> tags -- this resolves bugs such as 5550, where for
example, inserting a table using the WYSIWYG editor causes
erroneous break tags to be created.

- Warning displayed if uploaded file exceeded maximum size allowed for attachments (and was therefors discarded).
- Attachments included in forwarded messages (from both single message display, or from forward of multiple messages from folder display).
- Max size definition moved to a single location in lonmsgdisplay.pm and lonfeedback.pm
- Some appearance changes in modify_attachments display (for attachements associated with discussion posts).
- Subdirectory for storage of attachment file in sender's userfiles directory changed from feedback to feedback/$now (i.e., current UNIX time) to lessen likelihood of file being overwritten by a sequent message with an attachment of the same name.

Localization:
- Added missing &mt() calls
- Corrected &mt() call
- Changed user display in discussion post to LON-CAPA-standard (username:domain)

Change arguments accepted by lonnet::appenv() to:

When discussion postings are not displayed to a user because of a COM block, FDBK button should not provide the user with a way to post to the discussion.

Checkbox for copying posted message to user's course blog not shown if discussion osting are blocked.

If resource is encrypted for the correspondent, encrypted symb needs to be used in message ID as it will be accessible in the student's Sent Folder.

- prevent waring on startup

Fix typo.

Include symb in msgid when sending feedback about a resource.

Include an error bit in msgid (1 if message is a "bomb" caused by an error when rendering a problem.

Include symb and resource title in messsage (<symb> and <resource_title> tags) when feedback is about a resource.

Navigate Contents page now checks for unread feedback or errors using symb instead of just resource url.

Navigate Contents page checks for resource context based on symb in msgid instead of in [url] included in message subject.  Backwards compatibility with old-style messages retained.

Subject for feedback messages about resources appends message title instead of url inside [].

Title on feedback page now avoids leaking unencrypted file name in cases where no title was assigned to a resource with hidden url.

When displaying feedback messages about a resource in a course, "Refers to" link displayed when viewer has corresponding course role selected includes symb in the link. Link text is now resource title.

"Refers to" link points to unencrypted resource url if feedback message is viewed under role other than original course, only if user has bre privilege for the resource, otherwise "Refers to" link is not displayed.

lonfeedback -- Some replacement of decode_symb() and &clutter() and &dewrapper() with &get_feedurl_and_clean_symb() for replies and edits of discussion posts.

lonfeedback -- More work on in ensuring hidden urls are encrypted or unencrypted as required.

bug 5037 - destinations for resource content, course content, or course policy can now be filtered based on sender's group memberships.

Use loncommon::blocking_status() to call block checking and generate information for display if discussion board access is blocked.

Restore blocking for bulletin boards.

Provide a message about blocking if a user attempts to edit or reply to a post when he/she is subject to a blocking event.

&check_encrypt() is needed in more places.  Work in progress.

Bug 4972

"Send Message" link now displayed when discussion is closed and hidden.

Also shown when discussion is blocked.

Bugs 1402 and 4309.

When a discussion posting is hidden or deleted, if that post was the last discussion item, then the entry in discussiontimes.db for the resource is set back to the timestamp of the most recent unhidden or undeleted post.

- sigh

- the coprrect typo fix. sorry about that

Apparently a typo.

My best guess about how to fix the syntax errors in this file.

- lots of \w -> probper regexp replacements

- typo

Posts to bulletin boards can now be added to a user's course blog (previously this was only the case for replies).

State of "Add to course blog" checkbox is preserved when user uploads attachments at secondary screen before returning to main composition screen to submit post.

Fixed a typo in &mt('Re: ').

Can set blocking of posting to discussion boards in a course, and to a user's course blog via FDBK.

More concise use of &mt() for internationalization.

Ignore the duplication of message in disnew() and disfolder(), for now, because disnew()'s days are numbered.

bug 4772. Duplicate discussion control bar at the end of the display of discussions to reduce scrolling.

Eliminate $_

Style - push() keys() sort() split()

For both bulletin boards and discussion attached to resources, filtered display of posts can now be based on group affiliation. For users with mdg or vcg privileges in the course, selection is from all groups, for others selection is from user's own active groups.

- BUG#4895, non-anon bulletin borad posting was broken

- missing end tag

Bulletin Board Posting screen looks better with "Click to add/remove attachments:" and attachments + preview buttons below the textarea rather than at the right side.

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

- sticking elments back in there (not needed in firefox but might be somewhere else)
- making the 'Edit an anon post then set the type to anon' JS work again

- convert to use radiobutton to select feedback destination

- had broken anon discussion posting in bulletin boadrs, fixed

Add wrap_symb methods to lonnavmaps::navmap and lonnavmaps::resource to wrap bulletinboard symbs. Use method for resource in lonfeedback and lonwhatsnew to wrap symbs for bulletinboards.

Simplify rewriting of $resource->symb for bulletinboards. More use of &wrap_symb() and &dewrapper().

- increasing the use of loncommon::get_env_multiple

- ENV -> env

- BUG#4021 print discussion setting smaller

- <algebra> works in FDBK

- $r->content_type -> loncommon::content_type

- <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

- Fixes the WYSIWIG problems, the problem is since we are setting the encoding to UTF-8 on the homewor page, adn we _aren't_ setting it on the feed back generation page, when the WYSIWIG editor generates a   it becoms what ever rthe local encoding that was randomlypicked represents as a non-breaking space. Which muck things up to hell and back. So the fix is set the encoding to UTF-8 everywhere.

- xhtml cleanups
- stuck in a bunch of <label>s

- more icons -> lonhttpd

- more lonhttpd redirects

- making  few more logos go against lonhttpd

Export to IMS now exports discussion content - uses lonfeedback::listdiscussion().  Modification to export of templated documents (syllabus, aboutme, simplepage etc.) to IMS. Simple problems now converted to standard LON-CAPA problem format before export to IMS. Same routines could be used to dump simple problems to CSTR.

Correction to href value for discussion content in IMS export.

Fix so symb is available to create the redirect after clicking "Show all posts" link. Required for 1.137 and later.

Sections in Sort/filter display come from loncommon::get_sections().  Some small display improvements.

Fix bug #3607.  Extend filtering to support multiple selections of roles and/or sections.

- er typo?

Need to pass $symb for discussion_open() to determine if discussion is closed.

Correcting indentation

- encrypturl on discussions should be complet now
	- attachements work and url stays encrypted
- tested with both normal resources and bulletin boards

- off is 0 and on is 1, what a novel concept. :-)

- some more consolidations

- okay convinced myself that chgread never matters, discsymb takes care of it

- moved some $r handling in redirect_back

- restoring indiviual post read/unread toggle form

- even more better encrypturl support in discussions

- ugly, but ixes BUG#3603

Saving my work: cleanup

- adding use lonenc in needed places
- reenabling encrypturl in DOCS

- DISC properly handles encrypturl

- add in an untieHashes

 backport changes from lonnavmaps 1.297 and 1.299, and lonfeedbak 1.127 and 1.128

Fix bug #3515. identification of resources with discussion now occurs in lonfeedback after 'Mark all posts as read call'. To simplify further we might want to eliminate the extra code in lonnavmaps, called when sort is by "Has Discussion" and always do the resource->has_discussion call in lonfeedback.

- always pass navtime
- mark posts read as of navtime

- my backport wasn't correct

- eliminating the visit counting for 1.2, will return in an improved form in 1.3 and right now it is just slowin things down

- backport 1.126

- eliminate the get call on disc prefs, already in $ENV

-  elimintate the screnname/plainname calls already have them in the message

- backport 1.123

Eliminate debugging messages. Indentation changes. Save messages from replication of attachments for IMS.

Escaping discussion post subject and content in attachments upload display.

Fix bug #3469. Make sure that hash values are not only defined but also are NOT ''.

1. Guy's fixes so close date for bulletin boards work correctly, and advanced users can still see posts after close, when display blocked fro students.
2. A fix so subject and comment are preserved when added via HTMLarea during round-trip to add attachments screen.
3. Clean-up: sub build_ims() no longer needed. Export achieved via other routines.

- backport 1.120 1.121

 add <br/> to make things prettier

- add continue links

- typo

- somedays I can speel.

- backport 1.113

- bug#3385, non-htmlarea feedback fails on IE

- logic was incorrect, and thus invalid html was generated in tex mode and thus printing broke.

Moved construction of display of each discussion posting to subroutines (build_posting_display, get_post_contents, get_post_versions, get_post_attachments).  Added support for export of postings to IMS package (still needs additional work).

Cleanup for bug 2838 is done.

Bug 2838 (print attached discussions too) is fixed (finally). I am open to change any info (which can be relevant or not) but the general scheme seems works.

XML now used to store information about multiple attachments.  Still to do: option to set display of attachments inline in post.

Versions of messages and subjects in discussion posts stored in XML.

User can now toggle read/unread for individual discussion posts.

Editing now works for bulletin board posts.

Course Coordinators (and others with lonnet::allowed('rin',$crs)) can now display all versions of a discussion post.

Allow multiple attachments in discussion posts.  Different edited versions can include different (or the same) attachments.
Work still required: clean-up interface, change storage of versioned attachmenturl, message and subject in .db file to XML, add interface for course coordinators (i.e., for lonnet::allowed('rin',$crs)) to display old versions of posts.
Known issues: Edits are not currently stored for bulletin board posts.

Spelling links

 - remove 1.104 and backport 1.105

Spellchecker in Feedback Preview (somehow again missing HTML tags)

More comprehensive fix for Bug #3232 - detects presence of HTMLarea at
runtime, since HTMLarea - even if the code is sent out - can "decide" to
not load.

- backport 1.104

 BUG#3232

- need to protect anything that is going to be put into a <textarea>

Allow posters to edit/delete their own discussion postings.  Controlled by
course parameter set via PARM. Previous versions of postings are preserved.
Deleted postings are hidden. Course Coordinators etc. will be able to see
all versions of postings (interface still needed). Editing currently works for
resource discussions, but not bulletin boards (work in progress).

Use filtering to control which posts are displayed.  1. Restrict display of posts to users with specific roles, status, sections OR 2. Select from list of users whoc have posted.  User interface needs more work.

Can choose different sorting mechanism for discussion posts. Interface provided for filtering of posts for display (by poster's role, status -active/inactive, section). Choices currently have no effect (work-in-progress).

1 - Single click to remove all speech bubbles from NavMap.
2 - Suppress display of link to open empty folder in NavMap

Bug fixes for colspan for threaded discussions, and inline display afetr storing new discussion settings.

Bug 3091 fixes.
Discussion settings now appear after posts, and made more succinct.  Change link goes to another page, where choices can be made.

Not implemented: (a) filtering using ENV{'user.adv'} to disable these options for students - I actually think students might find these options useful rather than confusing. (b) Code to allow user to make any changes also the default option (PREF) - will add this tomorrow.

Work still needed: (a) modify code that builds display when target is 'tex'

- saving some notes

Bug 2838 (print attached discussions too) is fixed.

Bug #3082: submission of feedback in non-htmlarea mode

- remove debug spew

- adding the ability to choose between whether 'closed' discussions are also 'hidden'
 - which is the last of BUG#2636
