bug 5560.  Passing $res->opendate($part) to &timeToHumanString(), was causing two arguments to be passed (a UNIX time and 'resource'). Passing $open causes just a time to be passed, so the second arg is really $type (start or end), and $format is correct.

Doing the same for $res->duedate($part) and $res->answerdate(), in case they develop the same pathology.

- BUG#5513 make use of the new level information to control what level gets checked for first access information

- BUG#5513 adding ability for EXT (and navmaps equivalent) to get the
  level that a parameter is set at

- keep same as lonhomework::due_date

- add ability to set the timezone of a course

- BUG#5468 - show duedate for practice problems on nav screen

- BUG#5387
   - resttimes helper wasn't including the top level sequence
     when attempting to reset inital access times for groups of users

- add randomly ordered notices to
   - nav maps (on display of folders)
   - printout (when printing for Students or Anon that it will not be
               randomly ordered)
(BUG#3960)

- bug#5275, responses are handgradable, so when checking for handgrability check the responses, and pulll that value up to the part

	Correct typos in documentation.

- dumping of lonnet::stored info has only the symb and the
  parameter escaped so need to push the unescaping off into
  the users of the dumped info (as a result resources with :
  in the symb work in STAT again)

Need to decrypt the symb contained in the message ID.

If the message ID contains a courseID and it's different to the current courseID
then skip the symb.

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.

Eliminating $_

Renaming unread_discussion() as discussion_info() and making the funtion more universally useful.  Can now be used to retrieve counts for all postings, or just unread postings (if 'unread') is included as an argumnet in the call (e.g., $resource->discussion_info('unread');).  Also if
called in array context, returns ($count,%info), where %info is a hash of a hash.  Outer hash keys are count number, inner hash keys are: subject, id, timestamp.

- some xhtml

- splitting the handlery bits of lonnavmaps from the functional components

- interval needs to have a value for us to care about it

- use task icon for tasks

- morphing to use changee help_open_menu calling

- hrrm, typo I guess.

- start_page doesn't want a &mt

Adding thin veneer to support ANGEL-style groups.

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

- backport 1.383

- the map url in the parameter definition is without a version

- BUG#4758 due date should beat interval

- backport 1.381

- reverting fix, will make the map_ elements be fully versioned like src_ is

- backport 1.380

- the map_(start|type|finish|pc)_  have deversioned  urls in them

- adding a response ID equal to the partid for .tasks

- handling timezones correctly

Bug #4718: really show first resource

- change add_entries to pass the hash

- start_page takes care of registering urls and the loadeventes/ unloadevents needed

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

- domain and username migth contain more than \w

Counts of unread posts was incorrect for bulletin boards, as unwrapped symbs are used in the keys when storing information about BB posts.

- page start end generalize

- switching to using the parmval accessor

- adding an is_exam tester

Retrieval of randompick parameter and parts array was incorrect in a couple of helper functions.

- switching two uses of dump to dump store

- migrating some functinality from what'snew collectors into navmaps

- switching to the maintained version of weaken

Quotes need to be changed in both places

- don't remove the ' it's sometimes' important
- fixing some mt ising so that RtL people have a chance of translating things

Accessibility:
* tell which folder to open/close
* tell what's a problem
Some i18n

- practice problems don't really count as problems

- add ability to check if something is a .task
- Make the Task part also look like a Task response

- backport 1.359

- BUG#4635 ext resources that ended in / caused oddities

- updating documentation getByUrl doesn't exist but getResourceByUrl does

- forward port 1.349.2.5

- this looks better, never show the text "Answer Available" for handgradable problems

- backport 1.355 1.356

- don't say answer available on handgraded problmes that are partially correct

- backport 1.354

Partially correct display

Separate checking for new posts from counting number of new posts for each resource.  Should improve efficiency by replacing multiple restores with a single dump.  Menu still to be added to allow $countunread (whether to count or not) to be user-configurable.

- backport 1.352 1.353

Remove unnecessary code, and modify check for existence of resource Id.

Modification to allow getResourceByUrl to return more than one resource object, if a resurce is used multiple times in a course. Former behavior - returning first resource s default. Will only return array if additional argument (multiple) is supplied when method is called.

Also added a method to return the version number for a supplied url, from the navhash.

Both used by lonwhatsnew.pm rev 1.33.

- backport 1.351

Bug #2644: Grading feedback shows as envelope in NAV.

Parameters can be set for resources, maps, and course by group.  Group-level settings trump section-level settings in the cascading parameter scheme. Spreadsheet changes to follow.

Use " to quote href='s for resources rather than '  this works better
because " is not allowed in resource names, but ' is and ' seems
not to be properly esCaped in the href links.   This (I think)
deals with bug 442.

- BUG# 4457 http headers were getting sent to early

Display timezone for absolute dates and times.

Support a format paramter in timetToHumanString (optional).  This is needed
tosupport the format parameter in the <displayduedate> tag.  The default
is the old behavior.

"Here" marker looks a lot better when symmetric

- bug #3885 again, so we also need to support problems that are right/wrong but have no open due answer dates set

- BUG#3885 - not open, but has a grade, need to tell the student if they are right or wrong.

- conditions now no longer apply to user with bre,F at all, however navmaps does annotate resources with 'conditionally hidden' when they would not normally see it

- BUG#4395

- can't get a navmap if you arent in a course

- elminate some dead code

- remove some debugging spew

- bringing tasks more generally into Lon-CAPA

- make sure "What's New" shows up if it is supposed to

- BUG#3753, launch window now when launching and not knowing what the next resource is, will present a screen with links to first resource, and to close the external navmaps window.
- also more links in the navmpas window control the loncapaclient window rather than open in the navmaps window

- add access to handgrade attr in lonnavmaps

BUG#4196, someone doesn't like the word next

- more horror of partial correctness

- sometimes postdata and post ysmb a re set but aren't very useful

- BUG#4130

- spcifying alts for need parts like folder opening anclosing (BUG#4137)

Well, it does use navmaps now ... but still a long way to go to actually
clean it up.

- eliding warning

- making it easier to reuse the parm data caching in lonnet
- making lonnavmaps use lonnet to get the parm data

- death to ::reply

- this isn't actually caching the data, so I'm not sure why it is pretending too

- wrap_symb ddoes the checking so no need to check it before calling it

- comment was seperated from it's function
- removed unneccessary copy variable

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.

- ENV -> env

- bug4023, was double lonhttpdurling the icon link

- propagating the showall parameter to hasResource, so control over whether redirect maps get collapsed cna be controlled there too. (BUG#4001)

- now that last_known is a symb we can easily find out where we just was

- <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

- 3rd parmval fixed up for BUG#1444

 - BUG#3883 need to show intervening blank maps sometimes like when grading an exam.

- make middle mouse button click work for those who aren't using the external navwindow BUG#3865

- BUG#3749

- need to pass symb to allowed somtimes, like when we are scanning the whole course and &symbread is likely to get things wrong

- when viewing navmaps in a 'sorted' mode make sure links to things in pages point at the item in the page

- page anchors and part anchors are clashing, disable part anchors if there already is a page anchor

- links to resources in .page uses the anchors in there
- anchors are now symbs
- anchors are now encyrpted
- symb passed is for the .page not the individual resource, fixes #3711

As we only display if the resource has 'NEW' posts, I think is more accurate.

BUG 3663 Fix inability to pop into resources with ' in their names as a
course coordinator.  Need to still check this for other roles as I have
a hunch the same issues are lurking for other roles as well.

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

- Nav properly curlocs encrypturl resource

- trying to get encrypturl to work

- reducing interdependencies

- teaching ->getNext about conditions

- fixes bug#3350 hopefully for good.
    - $navmaps objects never actaully got cleaned up due the resource objects in it holding a reference back to the navmap object, this meant the hashes didn't get untied and that we leaked memory
    - needs WeakRef

 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.

- updating navmaps and the help icons to use the lonhttpd daemon

- always pass navtime
- mark posts read as of navtime

- something like a 'What's New' button, sort by 'Has Discussion', sorts by title but only shows those that have discussion / error / feedback
- fix bug is switching back to everything
- break 'Mark As Read' for modes other than 'Sort By Discussion'

- backport 1.295

- speedup[ navmaps for people with large amount of email

- disabling the 'Marks As Read' link for now, to big of a performance hit

- backport 1.294

- we don't know where they are or where they are coming from, so don't step through the whole course looking for nothing

countResponses: responseIds returns an array ref, not an array.

- when viewing ext wrappered docs in remoteless mode, need to bust out of the frames

-

Added resource methods countResponses and responseTypes.

Guy's 8/30 modification so sort by title ignores leading spaces in titles.

- backport 1.288

- BUG#3466

- bug#3300 Go To -> Show Me

- different way of doing response id/type reordering

- put the mail/bubble column back in

Bug 3358: response types were not being reported properly
&extractparts reorders the array of respons ids but was not reordering the
(parallel) array holding response types.

Help icons and select boxes in one row when in main window to preserve screen real estate.

- remove log spew

- integrating Stuarts changes and some changes that I think improve them

- in inline mode when you close the window using the close link, need to update the main window to let itknow I am going away

- backport 1.279

- BUG#3351, nav might show the "wrong" year.

- inline remote with external navmap works well now

avoid internal server error when get by symb fails to find resource.

- okay much sexier now.
