File size checking for uploaded files

A new javascript file, file_upload.js, handles client side file size checking.
The function, checkUploadSize(), accepts an html file input element and a maximum
file size (in bytes) as input.  If the size of the file to be uploaded exceeds the
size allowed, a message is displayed the the element is cleared.  Server side
checking is still used if it passes this test.

Loading file_upload.js adds event handlers to file input elements with
class="flUpload".
    <input type="file" class="flUpload" />

It also looks for a hidden element with id="free_space" that contains the maximum
upload size.
    <input type="hidden" id="free_space" value="$free_space" />

The free space is usually calculated by subtracting a user's disk usage from their
quota allowance.  In some cases it is a fixed value.

I have implemented this for every upload instance I could find.  These include:
* Message attachments
* Authoring space
* Portfolio
* Course editor
* Essay response problems
* Helpdesk request forms
* RSS feed uploads

- For 2.10
  - Backport 1.253 (bug 6710)

- Support for submission of files to externalresponse.
  - New routine: &portfiles_versioning() in lonnet.pm called after grading
    externalresponse to handle versioning of submitted files in portfolio.
  - &get_next_version(), &version_selected_portfile(), &file_name_version_ext()
    moved from grades.pm to lonnet.pm to facilitate re-use.

- Bug 6690
  - IP-based access control for portfolio files added to existing "conditional"
    access types used to grant read access to others besides the owner.

- Bug 6710

- Wrapped buttons in paragraph
- Improved check files message and moved it under the selected files table
  (better place because selection does not take place in the selected files table)

- Use LON-CAPA standard data tables in Construction Space and Portofolio Tables

- typo
- add missing .

Localization: Added missing &mt(...) and optimized some of the &mt() calls.
Still to do: change usage of &mt() for
  - "...-based" phrases

Block access to portfolio functions during blocking events unless 'evb' privilege.

Add blocking_status() - called by lonaboutme.pm, lonsimplepage.pm, lonfeedback.pm, portfolio.pm to display block condition

blockcheck() modified so blocking condition is only checked for current course for discussion, chat and group homepage

blockcheck() also modified so that if check is being made for blocking conditions for other than current user (e.g., portfolio files, blogs), check is made for 'evb' privilege for current user for any courses being checked for blokcing conditions.

Show information about how to get to get viewable group portfolio files

Add "Group Files" button to Course Documents Editor to allow iaddition of a course's "aboutme" page which includes information about group files

Add documentation for "Group Files" button

Users with "mpq" privilege for a domain can set and modify the portfolio quota for a user in the domain.

When a user uploads a file to his/her portfolio, the user's portfolio quota is retrieved, if one has not been set, the default for the domain is used, if no default has been set, the original static value of 20 Mb for backwards compatibility.

In the future we might want to consider different defaults for different types of user in a single domain.

Selection of roles, access types, sections and groups for each entry in a course-based condition for access to a portfolio file now occurs in a separate window.  Display of select boxes occurs immediately for new entries for existing course-based conditions, but after course selection via lonpickcourse for new course-based conditions.  Results of choices are stored in hidden form elements in opener window.

Added the help link to file actions (also added the help file)
Changed the manual (texxml file) to include help on catalog

Setting of conditional access controls now occurs on a seperate screen from setting of public and passphrase-protected controls.

Comments are appreciated. Thanks

&mt() an additional error message.  Loop through keys of hash.  Stop concatenating keys when creating new access control record for a renamed file.

- style
- correcting mt usage
- only cycle through the keys in the has

Deleting or renaming portfolio file deletes access control records for old file name (renaming and deleting) and adds equivalent ones for new filename (if renaming). Not fully tested.

When "aboutme" page is called for a course, link to listing of group portfolio files is available.  Page containing listing now separates files by group, and includes working links to files (with metadata CAT button).

	Allow multiple versioned file "folders" to be opened and closed
	independently.

	After seeing lock info of versioned file, return to opened
	"folder" of root file.

- backport 1.160

- backport 1.126

File sizes for uploads to course group portfolios may not exceed quota set for group's file repository. When creating a course, a quota can be specified.  The sum of quotas assigned to all groups in a course can not exceed the total quota defined for the course (when the course was created).  - client side and server side enforcement still needed here.  Portfolio permissions modified to allow any user with group creation rights in a course access to all course group portfolio functions.  All uses of words: group, Group, course and Course in "Course Groups Manager" now replaced with context-sensitive terminology provided by loncommon::course_type() and loncommon::group_term() which will supply appropriate text once a decision is made on Group vs Group. Currently "ANGEL-like Discussion Groups" are called Groups, regular courses are called Courses; and within regular courses sectionesque units are called groups, and within Groups they are called teams.

- backport 1.125

- adding version header

- backport 1.124

- select mode was broken BUG#4845

- reenabling user/course restrictions screens for CVS HEAD

- disabling the user/course restrictions screens from 2.2

- disabling user/group access restrictions screen for 2.2

- was producing invalid xhtml, colors aren't correct yet though.

Enforcing privileges for actions on course group portfolio files. Tabular display of access controls provided for group members with access to group repository, but without privilege needed to add/delete/update access controls for group files. Some text improvements, and case fixes for triggering correct roles nomenclature when dependent on Course/Group context.

- cstr space and portfoli now use same css attr to enusre similarity of display

- using css for all permissions changes

- eliminating last <font> in portfolio

- switching file browser to CSS (some of BUG#3925)
- errors now use span class="LC_error">
- filenames now using span class="LC_filename"

Need to include $content =  $$access_controls{$item} if you're going to eliminate the call to lonnet::parse_access_controls() -- see rev 1.109.

- start on BUG#3925 (make colors in port match CSTR)

- xhtml valid in directory display

- <nobr> -> <span>
- add in missing </select>
- POST ->post
- valid html page now

- empty rows aren't legal xhtml

- correcting some udage of the data_table

- eliminate xml for access settings

Additional portfolio access control can now be defined: passphrase-protected, or conditional access (requires log-in) based on username/domain, domain, course or group affiliation (possible restriction by role, status, sectio and group).

- <label>

- style

	Saving work in progress. Get version info available in directory

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.

file_permissions.db now stores information for each file as an array of arrays and a hash. In the hash, keys can either be accesscount or access. For key = access value is an anonymous hash containing key=value pairs defining access controls. For key = accesscount, value is a scalar (integer to be used when creating the next accesscontrol). Documentation added.

Work in progress.  Adding access control entry to file_permissions.db.  Current implementation is as additional arrays in array of arrays for each key (key =f file name - including path). New arrays contain either 'access' or 'accesscount' as first element.  These will become hashes in the next iteration. Added column to portfolio directory displays to show access status.  Some fixes to paths to handle coursegroup portfolios - e.g., new &prepend_group() function.

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

- create the droups dir if it doesn't exist

&coursegroups() and &get_group_settings() moved to longroup.pm, which contains general utility functions for asking about groups.  Also contains &group_changes() which is used to add/drop group memberships as a result of role changes, as determined by group settings for auto-add and auto-drop. 'none' and 'all' are now reserved words which may not be used as section or group names, so they can be used instead of _all and _none  when specifying auto-add and auto-drop settings for all sections or no section roles.

- changing loncommon::coursegroups to be easier to use

- er typos

-elimintaing some use of &bodytag in favor of &start_page instead

- converting some interface pages to stop generating </body> <head> </head> </html> and use the helper functions instead

Portfolio concept extended to include upload of files to a "portfolio" area within a group in a course to facilitate sharing of files in small instructor assigned teams in a course.  If this ends up being used, work on lonmeta will be needed, and control of who can upload/delete etc will need to be enforced using user's prvileges in the specific group.

- properly handle files like a.txt.pdf and ones with no extension

- currentpath should already contain a / and not contain portfolio

- cat link fixed to work with subdirs
- icon fiexed to display correct icon

- handelers need to always return something

- trying to use 'catalog information' rather than 'metadata'
- I think 'associating' with a course is a better way of presenting this to a user

- hide the 'files from other dirs' message unless there are othe files.
- add some text to the upload/create dir fileds to make them more obvious

- filesize already was divided by 1000

- BUG#4292, quota calculation was incorrect

	Delivers somewhat useful lock info, and a way back.

	Suppress display of versioned files.
	Begin display of reason a file is locked.

	Fix problems in file selection for essayresponse

- ENV -> env

- according to the perl docs the use of $` or $' slows down all regexps in a program so elimnating them

	change uri to direct to explict edit uploaded (portfolio) file

- I think this is a better direction to head with network transparent editing of files

	Remove .meta files from the portfolio directory display.

	Remove sub dedicated to file select (for responding to essay
	question) and integrated special file select stuff within
	the "standard" portfolio file display. This in preparation
	for making the two displays much more similar.

	Bug 3919: Better error messages for uploading files.

- <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

	Better fix (I think) for losing inline menu in file select.

	Address bug 3917. Suppress menu when portfolio in select mode

	Changing tack, removing duplicate code.

	Saving work. Still approaching meta data.

	Sneaking up on portfolio file meta data. Not there yet.

	Convert reported diskusage from bytes to kbytes.

	Remove "logthis" debugging stuff.

	Inform user when new directory name is changed by cleaning.

	Inform user when filename clean changes their filename.
	Inform user file must be checked to be deleted.
	List multiple files to be deleted on separate lines.

	Multiple file delete now works.

	Saving work in progress.
	Now not offering rename or delete actions if file is locked.
	Eliminated dropdown action select, replaced with checkbox for
	delete, and a 'rename' link.
	Rename works with link.
	Checkboxes for multiple file delete NOT WORKING yet.

	Thought I was right, but I was wrong. Javascript is not java script.

	Actually works once. Need to work out logic for clearing the
	file storing selected files, so files are "preselected" on
	subsequent visits.

	Another step toward submission from multiple directories.
	At least now it LOOKS good to the user! Now to actually
	submit the selected files.

	Saving work in progress. managing selecting files from
	multiple directories.

	Use cleaned filename so commas are removed so comma can delimit filenames.

	Navigating using the recent dropdown now retains select mode and
	parent field information.

	Fix for bug 3621 (plus unmentioned bugs 3621.1, 3621.2, etc.
	Fixes lost select mode while uploading files in portfolio space,
	as well as creating directories, and navigating directories.
	Also, fixes lost destination window (in javascript) so after
	navigating, uploading, etc., selected files are returned to
	parent window.

	Answering rhetorical question (i.e., rewriting to use new
	Apache::lonnet::is_locked subroutine).

	Cannot rename or delete locked files. (Still need to improve
	user interface to remove delete and rename options for locked
	files.)

	Include path information with submitted files.

	Reads list of locked files (submitted in essay response)
	Still needs to do something with the list in restricting
	actions on locked files.

	Added 'mode' to list of QUERY_STRING fields to process

Fixed warning on startup (use of '=' in conditional).
"=" should be "==" and in the case of string comparison "==" should be "eq" :)

	Permit upload of files during fileselect
	in responding to essay problem.
	Still need to confirm ability to navigate directory structure,
	and create directories in file select mode

	handle properly named field from essay response

	Added beginning of javascript sending selected files
	back to opener.

	Still not working.

	Nowhere near ready, but saving work in progress.

- really fix the style

	Prohibits deleting of portfolio root

	Fixed indenting and re-cuddled else

	Removed Fixme, hoping this is a better way to handle
	the no_such_dir condition.

	Remove superfluous line, rewrite call to remove_recent.

	Remove deleted directories from Recent dropdown.

	Added explanatory message if user clicks Upload with no file
	selected.

	Some formatting changes, hoping style police approve.

	Removed superfluous '/' added to $href_location owing to leading and trailing '/' in
	$current_path

	Added additional Fixme comment to remove dead directories from recent pulldown.

	Removed unused routines.

	Corrected error in earlier submit. Removed " character I had erroneously inserted in
	make_anchor routine.

	Disk quota enforced for portfolio. Currently hard-coded at
	20000k (20 meg).

	Also added Fixme messages for expensive routines that need to be
	re-worked.

	Fixme #1 removed: Improved error message for trying to create
	a subdirectory when a file or directory by that name already
	exists.

	Fix bug for first time user of portfolio. Create portfolio
	subdirectory off of userfiles.

	Adds call to lonnet::diskusage in fileupload. Eventually to
	enforce quota, now for debug.

	Cleaned up formatting, removed redundant sub clean_filename,
	removed Fixme comment

	Does not allow overwriting existing file when uploading.
	User instead receives this message:
	Unable to upload $filename, a file by that name was found in $path
	To upload, rename or delete existing $filename in $path.

	On delete directory, resets current_path to parent of
	deleted directory.

- style police

	Now handles delete of empty subdirectory

- make it easier to get back to /

- clean up entered dirnames

- rename is working

- things are now sorted

- can create directories now

- delete works, (and upload)

- much refactoring

- some style police management

- adding in some starts at file management
- make downloading possible
- fill in some fields

	Recent dropdown now populated through lonhtmlcommon routines

	File upload working now:

	Now has subdirectory navigation that looks and acts like
	construction space.

	Moving toward a contruction space look and feel
	Real Soon Now

	Still full of debug code, (and not yet functional) but showing
	entire directory structure from /userfiles/portfolio on down
	(recursively), with path information appended to array elements
	returned by lonnet::dirlist
	To do: combine returned directory array with user display prefs
		to allow navigation of directory struture

	Completely broken at this point, but approaching a better way of
	seeing/managing directory contents.

- correcting to use propath

	Page now looks like a lon-capa page. No more dogfood.

	Corrected style violation.

	Now uses lonnet::dirlist instead of lonnet::portfoliolist

	An effort at community style policing, plus removing lots of debugging
	and early dead-ends.

	Modified to use lonnet::removeuserfile, and lond ls function
	Still not complete.

- adding some FIXMEs and xhtmlizing the HTML

- retabinate

I seem to remember fixing this before...

	Still very much under construction. Beginning of directory
	navigation is working. Upload seems to work, but needs to be
	made more secure.

	Immediate to do:
		Delete files
		Create subdirectories
		Make all actions context sensitive

Minor fixes to get it to compile and do so without complaint.

	cosmetic changes, mostly

	Added GPL header

	Shows directory listing of userfiles/portfolio/
	allows upload to userfiles/portfolio

Raw beginnings of portfolio handler: This creates the file upload
form, in anticipation of receiving and storing the file in the user's
portfolio directory.
