Copied from: branches/rel-2-4-dev revision 5320
This commit was manufactured by cvs2svn to create tag 'rel-2-4-0'.

Revision 5320 - Directory Listing
Modified Mon Aug 13 23:04:20 2007 UTC (6 years, 8 months ago) by sh002i
Original Path: branches/rel-2-4-dev
updated version numbers

Revision 5318 - Directory Listing

Original Path: branches/rel-2-4-dev
updated copyright dates

Revision 5317 - Directory Listing
Modified Mon Aug 13 22:26:46 2007 UTC (6 years, 8 months ago) by sh002i
Original Path: branches/rel-2-4-dev
backport (jj): Sort entries which will appear in the library browser
(chapter titles, section titles, etc.).

Revision 5316 - Directory Listing
Modified Mon Aug 13 22:26:07 2007 UTC (6 years, 8 months ago) by sh002i
Original Path: branches/rel-2-4-dev
backport (jj): Revise how institution will be dealt with in the problem
library.  Currently, the information is not used so the changes are
innocuous.

Revision 5315 - Directory Listing
Modified Mon Aug 13 22:24:07 2007 UTC (6 years, 8 months ago) by sh002i
Original Path: branches/rel-2-4-dev
backport (dpvc): Backing out of Mike's change to previewAnswers.
Setting that to 0 means the grader will not be run when the problem is
first shown, and that means the notes provided by the grader (like "You
can earn partial credit on this problem") won't be shown until the
student first provides an answer.  These messages are important,
particularly for sequential problems, and so need to appear even when
the problem is first shown, not just when answers have been submitted.

If Mike had another reason than just efficiency for not processing
answers on the first invocation of a problem, that will need to be
handled in a more sophisticated way.

Original Path: branches/rel-2-4-dev
backport (glarose): Update ProblemSet editing to take out editing of set
headers for gateway tests; this is a bit of a hack to deal with the
problem that editing/trying the set header fails for a gateway test.  In
that the set header file isn't used for gateway tests I think this is
probably reasonable behavior.

picks out the studentID which is usually in the first column.

This is a temporary fix.  We should change the scoring and merge
features to use the login as the primary key. That can await a general
cleanup and code factoring for the scoring and grade calculations
throughout WeBWorK.

Added directory listing when a directory is being deleted.  The

top level contents of the directory (with numbers of items in the each

Modified Wed Apr 18 23:22:31 2007 UTC (7 years ago) by dpvc
Original Path: trunk
Update to v3.4a, which includes:

* Fixed a problem with the noImageFonts plugin where extra fonts would
still try to use image fonts even when they were supposed to be
disabled. Also, noImageFonts now adjusts the error message to indicate
that unicode fonts will be used for fallback rather than image fonts.

* Fixed a problem where changes in the CSS line-height attribute could
cause alignment problems with arrays in MSIE.

* Fixed a number of alignment problems with MSIE when used with a
DOCTYPE that triggers "standards" mode rather than "quirks" mode.

* A bug fix needed for MSIE6 that is one of the sources of jsMath's
slowness with MSIE is now disabled when MSIE7 is used, since it is no
longer needed in that version. This should give a noticable speed
improvement for jsMath in MSIE7.

Modified the way the Parser-based versions of the traditional answer

getCopy to obtain the copy either from the problem's context table or
the default table (rather than only from the default).  That way the
instructor can use parserCustomization.pl to customize the contexts
used by the answer checkers.

Original Path: trunk
Add set-level proctor login password for proctored gateway/quiz
assignments, improve handling of proctor keys and permissions for
proctored assignments, bug fixes for recently added features.

This commit
 - adds the ability to specify a set-level proctor for proctored
   gateway/quiz assignments.  this is done by adding a proctor with
   a username "set_id:setName", where "setName" is the name of the
   set, adding a "restricted_login_proctor" field to the set tables
   in the database, and allowing Authen::Proctor and
   ContentGenerator::LoginProctor to appropriately deal with this
   possibility.
 - updates proctor permissions and status in global.conf.dist,
   changing the old "proctor_quiz" permission level (3) into two
   levels, "proctor_quiz_login" and "proctor_quiz_grade".
   wwdb_upgrade includes a stanza to make this change to proctors
   that already exist in courses.
 - adds a "Proctor" status in %statuses in global.conf, with no
   valid behaviors.  this allows the creation of proctor users
   in a course who have the permissionLevel to login (and thus
   proctor), but not to access the course.
 - improves GatewayQuiz explanatory messages when scores or work
   are hidden.
 - improves GatewayQuiz proctor key management, especially for
   tests with more than one allowed attempt.  this includes
   adding a deleteAllProctorKeys() method to DB.pm.
 - updates Instructor Tools, UserList.pm and ProblemSetDetail
   to deal with set-level proctoring.  c.f. the note below about
   the ramifications of these changes.
 - updates ProblemSetList to deal with new problem set fields
   set_locations and set-level proctors that are located in a
   different database table than the set data.
 - fixes bugs in UserList and ProblemSetDetail dealing with the
   setting of hide_score, hide_score_by_problem, and
   time_limit_cap.

This update hides set-level proctor users from the classlist
editor (UserList.pm) and instructor tools (Index.pm) interfaces.
They can be created, modified, and deleted at the homework sets
editor page (ProblemSetDetail.pm) only, and there only implicitly:
we never indicate that a user is being created or modified behind
the screen.

Modified Mon Apr 2 20:58:49 2007 UTC (7 years ago) by glarose
Original Path: trunk
Update ProblemSetDetail to set both hide_score and hide_score_by_problem
set fields with a single selector.  This is general, in the sense that
it should allow other combinations of fields to be set if that's
appropriate.  This is a tentative commit; we may choose to back out the
changes later, especially if the data model for hiding scores is
changed.

Some bugfixes, preliminary commit of relax_restrict_ip function.  this
commit
 - adds relax_restrict_ip and hide_score_by_problem columns to the set
	and set_user tables

	restriction when no addresses exist for a location, makes it
	use any cached set that may be available, and makes it honor
	relax_restrict_ip
 - corrects a typo and some comments in DB.pm
 - allows ip restriction fields in ProblemSetList when importing from
	or exporting to set definition files
 - updates ProblemSetDetail.pm to handle the relax_restrict_ip field

  - moves javascript code for gateways into htdocs/js/gateway.js,
  - updates the gateway template to use that,
  - updates the gateway CSS file to use Louis Zulli's workaround
    for IE6 not honoring position:fixed, and adds CSS definitions

  - updates the GatewayQuiz module to print a score reporting box
    for multi-page, multi-attempt quizzes,
  - updates the Grades module to correctly sort problems for
    GatewayQuiz assignments that have randomly ordered problems, and
  - adds some error checking to ProblemSetDetail to avoid people
    doing things like submitting a zero time limit for a gateway.

Second preliminary commit of changes to move set-level valid checks to
Authz.  This makes ProblemSet.pm and Problem.pm use the
$self->{invalidSet} value set by ContentGenerator.pm, and means that
regular homework assignments may now be restricted to specific IP
addresses.  This commit also corrects $userName/$effectiveUserName
errors I had in Authz->checkSet() and moves the actual IP address
checking to a separate subroutine in Authz.  Hardcopy.pm uses that
routine to filter sets to be sure it doesn't generate hardcopies for
a IP address restricted set.

Revision 4907 - Directory Listing
Modified Tue Mar 27 17:13:31 2007 UTC (7 years ago) by glarose
Original Path: trunk
Preliminary commit of changes to Authz.pm and ContentGenerator.pm to
move set-level checks for set validity (set is open, published, IP
address restrictions, etc.) out of the individual ContentGenerator
modules.  ContentGenerator now uses Authz::checkSet to check these
and stores any return message in $self->{invalidSet}.  Individual
ContentGenerator modules can take advantage of this by checking the
value of $self->{invalidSet} that is preset (thus, this change should
be transparent for unchanged ContentGenerators).

Revision 4894 - Directory Listing
Modified Thu Mar 22 13:50:07 2007 UTC (7 years, 1 month ago) by glarose
Original Path: trunk
Added authentication mechanism Cosign.pm.  This implements WeBWorK
authentication using cosign[1], an open-source single sign-on system
developed at the University of Michigan.  This should be a reasonable
model for other modules implementing external, directory or location
based, authentication for WeBWorK.

To use cosign authentication for WeBWorK, set $authen{user_module} in
global.conf to WeBWorK::Authen::Cosign, and then configure apache to
require cosign authentication to enter WeBWorK courses.  If $cosignoff
is set to a true value in the course environment, standard WeBWorK
authentication is used for that course.

Note that cosign is a cookie-based authentication system.  This means
that it is between very hard and impossible to authenticate multiple
users on the same computer/web browser at the same time.  Thus it is
not possible to have both $authen{user_module} and $authen{proctor_module}
set to Cosign at the same time.

Implementation:
  Cosign.pm inherits from Authen.pm.  It redefines get_credentials to
force password authentication, and then assumes password checks succeed.
Because cosign is a Location/Directory based apache authentication
system, by the time the user gets to the Authen module we know that she
has successfully authenticated against cosign.  We also modify the
forget_verification method to return a redirect to the course environment
variable $cosign_logout_script.

Modified Thu Mar 22 13:39:50 2007 UTC (7 years, 1 month ago) by glarose
Original Path: trunk
Add support for external authentication systems.    This is appropriate
if something like an apache directory or location based authentication
system (such as cosign, basic or digest auth) is used.  In these cases,
WeBWorK may not handle the logout procedure, and we need information
from the Authentication module to determine the correct action.  We
allow for the case of redirects here, but this could easily be
extended if needed.

Implementation: pre_header_initialize() checks for $authen->{redirect}
to be defined and true after calling $authen->forget_verification().
If to, we set $self->reply_with_redirect to the value of returned by
$authen->{redirect}.

This update also moves key deletion from body() to
pre_header_initialize(), so that those actions take place before any
redirect.

Revision 4892 - Directory Listing
Modified Thu Mar 22 13:35:42 2007 UTC (7 years, 1 month ago) by glarose
Original Path: trunk
Add support for external authentication systems.  This is appropriate
if something like an apache directory or location based authentication
system (such as cosign, basic or digest auth) is used.  In these cases,
by the time the user gets to a ContentGenerator in the WeBWorK system
she has successfully authenticated against the external authentication
system, and so if there was an error it indicates that the user was
not allowed to enter the course for some other reason.  Thus, in this
case we print an error message and skip the WeBWorK login form.

Implementation:
  body() checks for $authen->{external_auth} to be defined and true;
if so, only the authentication error and an informational message
about the external authentication system is printed.  If undefined
or false, any authentication error is printed and the login form,
as usual.

Fix state retention when previewing or checking answers by retaining
page but not worrying about preview or answer check.  Reduce PG
translation for multipage tests by only translating problems on
submission or as needed when checking.  Clean up some calls to get
problems so that db->getAll... problems calls are used.  Add course
logging for preview, newpage, and grading.  Add "Show Past Answers"
form/button as appropriate.

Please note: there is an interesting question about the order in
which problems are logged for the case when problems on a test/quiz
are ordered randomly.  In this case, the problems are logged in the
course answer_log in the order in which they appear on the test.
However, when viewing grades and student progress, at the moment
this is not the case.  In the long run we probably want the grades
page to conform to the order shown in the test, while we may want
the student progress page to match the order seen in the actual
test definition.  For the moment that's probably a bug.

Completely rewrote the file to use a different technique.  Instead of
looking for unbeforeunload events (which didn't work reliably, since
Firefox will reload the page before it has a chance to install the
handler), we look for F5 key events and F5 ignore keydown events, but
reload the page on F5 keyup instead.  This skips the autorepeating
keys and only reloads the page when the user lets go of the key.  So
there is only one reload.  After several autorepeated F5 keypresses, a
dialog will appear asking you to check if something is holding down
the F5 key.

added mail_answers_to3, which currently does not work, to eventually
replace mail_answers_to2, which also does not work.

I thought now would be a good time to commit this, so that others can
look at it if they like. The problem is that when RestrictedMailer is
used within a PG safe compartment, it hangs on opening the SMTP
connection and the problem times out after 60 seconds.

This mockup I made works perfectly however, and I can't see how the PG
safe compartment is different. Here it is:

my $mailer = new WeBWorK::Utils::RestrictedMailer(
        params => {
                from => 'sh002i@math.rochester.edu',
                smtp => 'mail.math.rochester.edu',
                headers => 'X-Remote-Host: 128.151.231.10',
                debug => "debug.txt",
                keepconnection => 1,

        fatal_errors => 1,
);
my $rmailer = new WeBWorK::Utils::RestrictedClosureClass($mailer,
        qw/Open SendEnc Close Cancel skipped_recipients error error_msg/);
my $safe = new Safe;
${$safe->varglob('the_date')} = `date`;
my $hole = new Safe::Hole {};
my $rmailer_wrapped = $hole->wrap($rmailer);
${$safe->varglob('TEST')}{rmailer} = $rmailer_wrapped;
my $result = $safe->reval(<<'EOF');
my $rmailer = $TEST{rmailer};

Abstracted the NumberWithUnits to a more general ObjectWithUnits and
moved the FormulaWithUnits to this file as well, since most of the
code is common.  Although, strictly speaking, FormulaWithUnits is not
legacy code, since the general object-with-units is here, it will be
easier to maintain FormulaWithUnits here as well.  When the Parser
gets a real units class, all of this can be removed.

Also fixed the unit lookup code to use the actual names from the Units
library, so we can now be more accurate about determining the extent
of the units, and can handle things like '5 kg m / s' now.  In the
case of ambiguous formulas with units, e.g., '5m kg' where m is a
variable, use '5*m kg' or '(5m) kg'.

The Units.pm library only accepts one division within the units, and
the Parser wasn't taking that into account, so students could enter
m/s/s and still get credit even if the units were m/s.  This have been
fixed.

Modified Sun Nov 26 23:59:22 2006 UTC (7 years, 4 months ago) by dpvc
Original Path: trunk
Provides a formula with units (as opposed to a number with units).
This does introduce some ambiguity issues, since variable names could
look like units in some cases.  E.g., s + 5 m/s could look like
(s + 5*m/s) rather than (s + 5) meters/second.

The parser will take the largest string at the end of the answer that
could be treated as units so s + 5m/s is (s+5) meters/second.

The Units.pm library requries units to be separated by * or / and
only one / is allowed, so s + 5m s is (s+5m) seconds not (s+5) m*s.

Something like 5 m/s/s will generate an error (it shouold be written
m/s*s or m/s^2), and 5 kg m/s should be written 5 kg*m/s.

[If we made the hash of known units be public rather than private in
Units, we could do a better job of this, and could treat kg m/s as
kg*m/s for example.]

"num-correct" in determining the grade for the gradeSimple procedure.

Original Path: trunk
Update to version 3.3g:

* When the AMSsymbols extension is loaded, the \mathbb macro is now
  changed to use the blackboard bold characters that are in the msbm
  font. (In the past, this would occur when the msbm font is first
  loaded, but the change should be made right away, since a use of
  \mathbb should cause the msbm font to load if it isn't already.)

* Fixed a bug introduced in version 3.3f that causes tex2math (when
  used with autoload) to cause MSIE/PC to stop processing display
  mathematics in some situations.

* Fixed problem with \longmapsto that caused gaps between the
  characters that form the arrow. Also worked around a problem with
  Firefox that caused \mapsto to lose its vertical tick at the
  left-hand end of the arrow.

* Fixed a problem with autoload where multiple calls to tex2math could
  cause tex2math to convert \$ to $ and then later try to interpret
  the $ as a start-of-math delimiter, even though it was previously
  escaped.

* Reorganized the autoload plugin so that jsMath.Autoload.Run() no
  longer needs to be called. In the past, autoload would use tex2math
  to look for text that needs to be converted to SPAN and DIV tags of
  class "math", but would not convert them itself. Now that autoload
  has settings to control what tex2math functions will be performed,
  there is no need to put off the conversion, so autoload now does the
  tex2math conversion immediately. The
  jsMath.Autoload.findMathElements variable is no longer needed, and
  so has been depricated.

* Fixed a problem with tex2math where two escaped dollars in a row
  would not be processed properly (the second would not be treated as
  escaped, and so could be treated as a start-of-math delimiter).

this is the log message for the last version (v1.80): sweeping changes!

PLEASE NOTE THAT VERSION 1.80 AND LATER OF DB.PM WILL NOT WORK WITH
MOODLE UNTIL I UPDATE THE MOODLE SCHEMA MODULES (which should happen
soon).

WARNING: VERY EXPERIMENTAL CHANGES. DO NOT USE ON PRODUCTION SITES.
MAKE A BACKUP OF YOUR DATA BEFORE USING.

replaced ad-hoc argument checking with calls to checkArgs and
checkArgsRefList. this makes the code much more concise and readable.

no longer checking for existence before adding a field -- instead catch
a RecordExists exception which is thrown by NewSQL classes. this will
speed inserts of slightly.

added count* methods for all tables.

switch to using newer NewSQL methods where they'll be more efficient or
readable.

generally regularize code -- resolve indentation problems, get rid of
extraneous empty lines, etc.

rewrote getMergedSets, getMergedProblems, and getAllMergedUserProblems
to use NewSQL::Merged (via set_merged/problem_merged "tables"). The new
merge method (which is done completely withtin the database) is more
than three times as fast for normal merging and more than seven times as
fast for getAllMergedUserProblems.

here as having been completed in 20 min, not 21.  This avoids some

  want to add additional CSS rules to reset those within #jsMath_panel

re-adding courses.dist to just HEAD and rel-2-3-dev branches (see below)

i'm re-adding this directory using "cvs add" rather than by copying it
from "courses" in the repository. this avoids having it show up in older
release branches. the downside is that we lose the version history, but
i don't think that's a big problem.

removing courses directory (please read)

i originally moved the courses directory to courses.dist, to preserve
file history, but this wasn't the right strategy, since it caused the
courses directory to disappear from older branches as well. so i copied
it back to courses, and then used "cvs remove" to delete its contents.

so, it will hopefully exist in rel-2-2-dev and earlier releases, but not
in rel-2-3-dev or HEAD.

Added class to protect objects from evil prying problem code.

Uses the closure-as-object technique to protect the self hash of the
underlying object from problem code. All that the problem code sees is a
blessed coderef. The coderef is a closure over the underlying object and
the list of allowed methods. You can invoke the coderef directly, with
the name of the method to invoke as the first argument, but the class
also provides an AUTOLOAD routine that calls the coderef for you, so you
can continue to use the class as usual.

This file helps WW manage the browsers windows that it opens.  The
current approach is to use a separate window for the Problem Editor
and a third window for viewing the problem when you test it.  This is
fine, except that if you use the navigation links in the editor, those
pages will open int he editor window, and this can mean the editor
window is used for non-editing functions.  Worse, if you click on an
"Edit it" link in this window and expect a new one to open, you will
be surprised to see it appear in the current window.

This javascript file makes the editing window work as it was intended:
clicking on the navigation links opens those pages in the ORIGINAL
window again, not the editor window, so the editor window will be used
only for editing.  It also uses the main window for viewing the
problems, so there are only two main windows now.  This should
simplify the editing of problems.

To use this file, add

  <script src="<!--#url type="webwork" name="htdocs"-->/js/ww-windows.js"></script>

to the .template file that you are using just before the </body> (not
that it must be at the END of the page, or it may not work properly).

This will also fix a problem with Firefox where the editor window
woudl not come to the front if it already exists and inot the
front-most window.

'x+3' in a numeric field would not be reported as an error and x would

had been rerouted to die in PG_answer_eval().  I have replaced it.

fixed syntax of call to radio_group -- leading dashes are required.

the rule is (as defined by CGI::Util::rearrange):

* if the first argument is a hashref, interpret its contents as named
parameters. leading dashes can be used, but are not required.

* otherwise, if the first parameter begins with a dash, interpret the
argument string as named parameters. a leading dash is technically only
required on the first item, but you'd be nuts to mix dash and no-dash.

* otherwise, treat the argument list as non-named parameters.

These can be useful when you are writing many problems and wish to use your favorite

Fixed some of the param problems by adding   , override=>1  to the CGI::hidden() calls.
This means that CGI ignores any param() values when assigning value to the field.  We have been
assigning our own updated values in any case, so this is probably what should have been done
from the start.  I'm not 100% sure of this yet however, so I've only fixed a couple of places
in SetMaker.pm where the behavior is weird.  I'd like to here of other weird behavior that could
be attributed to values in forms sticking or not sticking correctly.

Install wrapper for param() method when running under mod_perl2. This is

I've gotten to the point where the login screen can be displayed, but

we modify $r->param values extensively in WeBWorK, and that is not
supported in Apache2::Request. I'm not sure why, and no workaround is
given. One solution is to wrap override param() in WeBWorK::Request, but
this would slow things down since the Apache2::Request param method is
written in C.

The last message was garbled.  I've added code that copies auxiliary files when you make a local copy or
an extra copy of a problem file of the form  prob4/prob4.pg

This copy mechanism is not yet used when viewing one of these problems from a temporary file in tmpEdit.  If you
have viewed a problem before you start editing it, your browser will probably use cached images and you
will not have any errors.  If you start editing a problem with auxiliary files before viewing it once in its original
state, then some of the auxiliary images might be missing.

Original Path: trunk
Fixed a couple more issues with blank problems.  Allow files to be
copied even when we can't write the original (this lets you make a
copy of the blank problem or default headers).

Attempt to overcome the copy/rename problem by making it not be a menu
and instead use a checkbox that says whether the problem or header
will replace the one in the current set.  This makes it clear that a
copy is still being made (not that the original is being renamed), but
that the homework set is being altered.  Those are really two
different actions, and it seems to make sense to separate them.  The
default is still to link into the homework set, if there is one.

Changed messages that refer to 'Save as' to use 'Create a copy'
instead (which is the current wording for that function).

Problem:  Since the default in that pop-up menu us "Rename file"
rather than "Create a copy", it is not immediately clear what this
message refers to.

I still think "Create a copy" should be the default rather than
"Rename file", since the latter only makes sense when you got to the
editor from a file linked to a homework set, which is not always the
case (e.g., when you use the Library Browser).  It would also make
these error messages refer to something visible rather than a menu
item that is not showing.

New files to bring jsMath up to version 3.3b.

Revision 4138 - Directory Listing
Modified Fri Jun 23 20:06:23 2006 UTC (7 years, 10 months ago) by dpvc
Original Path: trunk
Updated to version 3.3b.  See the change log on the jsMath web site
for details of the changes.

Some of the highlights are:

  Added an extension that implements the \font command. (Now that jsMath
  can auto-load fonts as they are needed, this is feasible to do.)

  Added \eqalign and \displaylines for creating multi-line displayed
  mathematics. Also added \eqalignno, but it works by putting the line
  numbers in a right-justified column separated by 3 em's of space from
  the rest of the alignment (rather than putting them flush right, which
  would be difficult without more substantial changes to
  jsMath). Finally, added \leqalignno, but the line numbers are placed
  on the right not the left (it is really just an alias for \eqalignno,
  and is included only for completeness).

  Added the ability to use \noalign{\vskip ...} and \\[dimen] to
  insert space within an array or alignment. This is not a complete
  implementation of \noalign; only \vskip and \vspace commands are
  processed, and this is only intended as a way of controlling the
  spacing between rows of a table.

  Adjusted the spacing within some alignments to better match actual TeX
  output.

  Added \mbox and \hbox to the commands that are processed correctly
  after ^ and _ (i.e., as unbraced superscripts and subscripts).

  JsMath's implementation of \raise and \lower are non-standard in that
  they do not require an \hbox, as TeX does; indeed using an \hbox would
  cause jsMath to fail (unless it were enclosed in braces). This is no
  longer the case, as these commands now handle \hbox and \mbox as TeX
  does.

  The addition of several new checkboxes on the jsMath control panel
  made the window for the control panel rather tall. This has required a
  reorganization of the control panel, and it now has a horizontal
  rather than a vertical orientation which better matches the aspect
  ratio of most screens.

In addition, version 3.3 introduced an caching mechanism that is
page-based, and "global mode" that allows for an inter-page cache.
This mechanism works with WeBWorK, but because the pages are so short,
it is probably not very helpful.  Also, turning on global mode will
require logging in again (due to the loss of form data when the page
is reloaded).

Implemented unarchiving function to complement archiving function.

Archive exports the course database to courseName/DATA and then tas and gzips the directory courseName to
courseDirectory/courseName.tar.gz

Unarchive allows one to choose files of the type courseDirectory/courseName.tar.gz  and then
ungzip, untar them to courseDirectory/courseName   -- the database record in courseName/DATA is
then loaded into the webwork database.

So far there is only minimal error checking about whether all or part of the course exists when unarchiving.

There are not yet features for archiving and then deleting a course -- these two operations have to be done
separately for now.

Set server root (-d) to $WEBWORKROOT, create "run" directory if
necessary. (This is for devel's Apache/SSL, which wants to put an
httpd.mm file in "$SERVERROOT/run".)

Original Path: trunk
improvements to URL handling.
* use use_abs_url option of systemLink to generate URLs, rather than
hardcoding logic.
* don't generate a full URL for the return to your work link. it isn't
needed.
* in the "This feedback message was automatically generated by the
WeBWorK system at" message, give the URL to the webwork home module,
rather than just the host and port.

Revision 4107 - Directory Listing
Modified Thu May 25 16:35:10 2006 UTC (7 years, 11 months ago) by sh002i
Original Path: trunk
added use_abs_url option to systemLink: If set to a true value, the
scheme, host, and port are prepended to the URL. This is useful for
links which must be usable on their own, such as those sent via email.

Original Path: trunk
changed how activity is determined. previously, check_session was being
called with updateTimestamp=1, which would cause all active sessions to
be "touched" so as to prolong their validity. also, it's not really
approriate to call check_session in this way to begin with. we already
grabbed the key, and we know it matches, so we don't want to grab it
again. so instead i just put the timestamp comparison directly into this
file.

see also UserList.pm 1.79.

tools.

Revision 4083 - Directory Listing

Original Path: trunk
modifications necessary to support moodle tables:

* respect non_native flag in dbLayout
* don't attempt to add users if user table is non_native
* rather than checking for the string "sql_single" in renameCourse and
  archiveCourse, and erroring out otherwise, we check to see if there is
  a copyCourseDataHelper or archiveCourseHelper implementation
  (respectively). new getHelperRef subroutine helps with this.

With these changes, courses with the sql_moodle dbLayout can be created,
deleted, renamed, and archived using the WeBWorK course management
tools.

Original Path: trunk
Resolve bug #994 ("Try it" yields:  sourceFilePath is unsafe!)

SetMaker uses a relative path for sourceFilePath, which is nice, but
which path_is_subdir didn't account for. Added thrid argument,
$allow_relative, to that utility which causes $dir to be prepended to
$path. Modified Problem.pm to trigger this behavior.

Use undefstr to convert undefined values to the string "###UNDEF###". If
you think a value you're sending to debug() might be undefiend, send it
as a separate item in the argument list rather than concatenating it or
interpolating it into a string. For example, say:

	debug("now myVal=", $myVal, ", exiting");

If $myVal is undefined, you'll see:

	now myVal=###UNDEF###, exiting

restrict width of info box to exactly 40% of the page width. we can't

set "overflow:auto" to enable scroll bars when the content can't be
wrapped to 40%. this is a little nicer than the contents running over
the border of the box, but MSIE makes bad choices about how to size the
box so as to avoid unnecessary scroll bars. (it sizes the element first
and then adds scroll bars, so it adding a horizontal scroll makes the
content area smaller than the content, necessitating a vertical scroll
bar as well. pretty annoying.)

Gateway update: don't display gateway sets in siblings sidebar of

Revision 3872 - Directory Listing

Added ability to specify variables that are part of the union/list
rather than requiring just constants.  E.g.,

       interval_cmp("(1,a),(2a-1,a)",unions=>'no',var=>'a');

or

       interval_cmp("(x,y),(2x,3y)",unions=>'no',vars=>['x','y']);

Revision 3869 - Directory Listing
Modified Sat Dec 31 14:57:39 2005 UTC (8 years, 3 months ago) by dpvc
Original Path: trunk
Added a new flag that controls how a list with a single entry that is
a list is handled.  In the past, the student could not specify such an
item, but now the default is to form a list with a single entry that
is a list, provided the student has used parens explicitly around his
list.  So "1,2" will be a list with two items and "(1,2)" will be a
list with one item (a list).  This improves the ability to use the
list checker for lists of arbitrary pairs (like "(1,max)") especially
when you want to check for lists of these (e.g., "(1,max),(2,min)"),
since otherwise a single pair "(1,max)" entered by the student would
become the list "1,max" rather than the list containing the single
pair.

If you really want "(1,max)" to become the list "1,max", use

   List("1,max")->cmp(implicitList=>0);

to prevent single lists from forming a list of a single item.

Now that the parser accepts multi-character variables, there is no
need for the special treatment of dx.  Also, allow the context to
specify the default variable to use, and if not available, take the
LAST varaible alphabetically, not the first.  (x is more likely to be
last, and the author might have added dx as a variable so that it will
not cause an error if used in other answers in the problem, for
example.)

Allow reordering to succeed even if some UserProblems are missing.
Addresses bug #878.

By the way, I found the reordering code really hard to read, so I added
a lot of comments and replaced multidimensional array accesses with a
shorter form. ($sortme[$j][0] rather than $sortme[$j]->[0].) I'd like to
maybe rewrite this code sometime to eliminate some indirection and make
things clearer.

There are two substantive changes:

(1) When a UserProblem has to get reordered, we only reorder it if a
UserProblem record actually exists. If it doesn't exist, we figure out
where it would have moved to, and delete that problem instead.

(2) When moving a UserProblem, the target location either contains or
doesn't contain a record. Previously, the code checked whether a
GlobalProblem existed in this location, assuming that if a global
problem existed the corresponding UserProblem would as well. Now, it
checks whether a UserProblem exists, which allows for missing
UserProblem records.

Lingering questions:

(1) When multiple problems are assigned the same number, this results in
the last one ending up first in the new ordering. I think it would be
more natural for the first one to end up first. This would be an easy
fix.

(2) $force always gets set if reordering needs to be done, so we aren't
able to delete a problem, reorder some other problems, and end up with a
hole where where the deleted problem was. We can either fix this by
mentioning this next to the force checkbox, or change it so that
particular holes (i.e. those left by deleted problems) are allowed when
reordering.

moved "minimal list style" to "div.Links ul" and "div.Links ul ul".
div.Links is a ur.template class, and the proper place for styling the

(Maybe it is not necessary to check for correct at all, since that was
there to prevent the message from being issued when there are multiple
answer blanks and the student is working on other ones.  But the exact
match check will take care of those.  Should the message be issued if
the student changes a correct answer to an equivalent one?)

Roll back Mike's change, since this can cause unwanted error messages
in list comparisons and other situations where the equality check
could compare different types of objects (for example) or where the
comparison could legitimately fail.  We only want to report errors
here when the user-supplied checker code fails.

This change would cause errors to be reported, for example, when the
user (incorrectly) entered a vector one time and then a formula
(correctly) the next time.  When the previous answer is checked against
the current one, this change would report an error rather than
silently ignoring the error, as it should.

	$GlobalSets[1] (ID Sec9.2ParametricEq) not defined -- skipping
	at /ww/webwork/webwork2/lib/WeBWorK/ContentGenerator/Hardcopy.pm
	line 286.

were coming from?
the answer is:

	$GlobalSets[1] = undef;

which is a line i put in there for testing and never removed. i am very
sorry. :-(

Added rudimentary link to report problems directly.  It does this by constructing a link
to the bugzilla CGI that includes information on the file name of the problem and the library

Refactored much of the action in PGProblemEditor.pm  This allows a user inteface
which mimics the interface for the Hmwk sets editor and for the Classlist editor.

It also allows all of the temporary edit files to be placed in one location.
This allows one to "temporarily" edit a library file to try to see what is wrong with it.

It is also now much easier to make a local copy of a library file for your current problem set
so that you can tweak it.

It has been fairly well tested by one person (me) but there may still be bugs.

Revision 3716 - Directory Listing
Modified Sun Oct 16 03:37:17 2005 UTC (8 years, 6 months ago) by dpvc
Original Path: trunk
In the past, when Value objects were inserted into strings, they would
automatically include parentheses so that if you had $f equal to 1+x
and $g equal to 1-x, then Formula("$f/$g") would mean (1+x)/(1-x)
rather than 1+(x/1)-x, which is what would happen as a straing string
substitution.

The problem is that this would also happen for real numbers, vectors,
and everything else, even when it wasn't necessary.  So if $x=Real(3),
then "Let x = $x" would be "Let x = (3)".

I have changed the behavior of the string concatenation for Value
objects so that parentheses are only added in a few cases: for
Formulas, Complex numbers, and Unions.  This makes the other Value
objects work more like regular variables in strings, but might cause
some problems with strings that are used as formulas.  For example, if
$a = Real(-3), then "x + 2 $a" will become "x + 2 -3", or "x-1" rather
than the expected "x - 6".  (The old approach would have made it "x +
2 (-3)" which would have worked properly).  For the most part, it is
easier to use something like "x + 2*$a" or even "x" + 2*$a in this
case, so the extra trouble of having to avoid parentheses when you
really meant to substitute the value into a string didn't seem worth
it.

Revision 3715 - Directory Listing
Modified Sun Oct 16 03:27:35 2005 UTC (8 years, 6 months ago) by dpvc
Original Path: trunk
Added a new experimental diagonstic function for the function answer
checker.  When enabled, it will produce graphs of the correct answer,
the student answer, and the absolute and relative errors, and will
list the data points used in the comparison, plus the numerical values
of the results and errors.

To enable the diagnostic, use

   ANS(fun_cmp($f,diagnostics=>1));

Note that only single-variable functions can be graphed at the moment,
so if you are using a multi-variable check, you need to disable the
graphing.  To do this use

   ANS(fun_cmp($f,vars=>['x','y'],diagnostics=>[showGraphs=>0]));

The diagnostic mode is only available for the Parser-based versions of
the function checker, and (of course) with the native Parser objects
as well:

   ANS(Formula($f)->cmp(diagnostics=>1));

There are now Context settings to control the diagnostics, which can
be set through Context()->diagnostics->set().  For example

   Context()->diagnostics->set(formulas=>{showGraphs=>0});

would turn off graphs for all functions comparisons.  Some of the
other values you can set are:

   formulas => {
     showTestPoints => 1,        # show the test points and function values
     showRelativeErrors => 1,    # show the relative errors for the student answer
     showAbsoluteErrors => 1,    # show the absolute errors for the student answer
     showGraphs => 1,            # show the various graphs
     graphRelativeErrors => 1,   #  show the relative error graph
     graphAbsoluteErrors => 1,   #  show the absolute error graph
     clipRelativeError => 5,     #  don't show relative errors above 5
     clipAbsoluteError => 5,     #  don't show absolute errors above 5
     plotTestPoints => 1,        #  include dots at the test points
     combineGraphs => 1,         #  show correct and student graphs in one image
   },
   graphs => {
     divisions => 75,       # the number of data points to plot
     limits => [-2,2],      # the lower and upper limit of the plot
                            #  (taken from the function limits if not provided)
     size => 250,           # pixel size of the image (could be [width,height])
     grid => [10,10],       # number of grid lines in each direction
     axes => [0,0],         # where to put axes relative to origin
   }

Any of these can be set in the Context(), or in the answer checker
itself.  If you set diagnostics to an array reference, the entries in
the array refer to element of the formulas hash.  If you set
diagonstics to a hash reference, then you can set values in either the
formulas or graphs hashes, as in:

   ANS(Formula($f)->cmp(diagnostics=>{
     formulas => {showAbsoluteErrors=>0},
     graphs => {size=>300, divisions=>100},
   }));

If you want all function checkers to show diagnostics, use

   Context()->diagonstics->set(formulas=>{show=>1});

The image file names are modified to include the current time so that
the names will be unique.  This avoids problems with the browser cache
showing a old image when a new one has been generated.  But this also
means that the temporary image directory will fill up fast, so you may
need to empty it if you use the diagnostic images frequently.

This is just a first attempt at a diagnostic feature.  I think it will
help when you are not sure if the tolerances are set properly, or if
you think a student answer should be markes correct but isn't, as it
will point out which point(s) are not being accepted.

Original Path: trunk
Added syntactic sugar for pop_up_lists.

A common situation is that a problem includes a short multiple-choice question along with other answers.  Often, these questions are written as fill-in-the-blank where the student is told a list of legal words to put in the blanks.  The idea is to make it as simple as possible for problem writers to replace the fill-in-the-blank with a drop-down list of alternatives.

So, now the text of a problem can contain

 is the function increasing on [0,1]? \{ pop_up_list(['?', 'yes', 'no']) \}

instead of

 is the function increasing on [0,1]? \{ pop_up_list('?' => '?', 'yes' => 'yes', 'no' => 'no') \}

The result is checked with something like

 ANS(str_cmp('yes'));

Existing problems are unaffected since the added syntax uses a reference to a list (the extra square brackets).

Add a new context flag that controls how the student answer should be

(the default), which shows the final numeric answer; 'parsed', which

clarity); or 'reduced', which performs constant operations, but
doesn't perform function evaluations or named-constant substitutions.

For example, if the student answers 1+2+sqrt(3), then 'evaluated' will
produce  4.73205, 'reduced' will show 3+sqrt(3), and 'parsed' will
show 1+2+sqrt(3).

Revision 3688 - Directory Listing
Modified Wed Oct 5 18:16:52 2005 UTC (8 years, 6 months ago) by sh002i
Original Path: trunk
Implemented status system as per bug #743.

The status system consists of a new hash in the course environment,
%statuses, that maps status names (like "Enrolled", "Drop", "Audit") to
(a) a list of allowed abbreviations for the status and (b) a list of
behaviors the system should have when dealing with users who have the
status.

I didn't want to have to mangle that hash-of-hashes-of-arrays myself in
many modules, but I also didn't want to devote an entire module
(Status.pm) to it. So, I'm trying a little experiment: I've added them
as methods to WeBWorK::CourseEnvironment. My thinkint is that since all
the data for these operations comes from the course environment, so why
not have them be course environment methods? Here they are:

    status_abbrev_to_name($status_abbrev)
        Given the abbreviation for a status, return the name. Returns undef
        if the abbreviation is not found.

    status_name_to_abbrevs($status_name)
        Returns the list of abbreviations for a given status. Returns an
        empty list if the status is not found.

    status_has_behavior($status_name, $behavior)
        Return true if $status_name lists $behavior.

    status_abbrev_has_behavior($status_abbrev, $behavior)
        Return true if the status abbreviated by $status_abbrev lists
        $behavior.

Since I removed the previous $siteDefaults{status} hash from
global.conf, I have already switched modules that formerly used that
hash over to using the new methods:

Authen.pm: use status_abbrev_has_behavior($status, "allow_course_access")
to determine if a user should be allowed to log in.

Feedback.pm: look up status abbreviation using status_abbrev_to_name()
and print the result for the status field in the email.

Instructor.pm: use status_abbrev_has_behavior($status, "include_in_assignment")
to determine if a user should be included in an assignment.

UserList.pm and UsersAssignedToSet.pm: use status_abbrev_to_name() to
get name of CSS class.

  ContentGenerator.pm: link in left panel to Config module

  CourseEnvironment.pm: evaluate simple.conf.  File name can be specified
    when creating a new CourseEnvironment.  This allows it to be bypassed
    (which is currently used), or to test a simple settings file (not
    used now, but it might be useful).

  Constants.pm: all data about configuration is stored here.  New values
    can just be added here, unless they are a new type.

  Config.pm: new module for limited course configuration.

Note, it might be better to move the new variable in Constants.pm to
another file.  Committing changes to Constants.pm can be an extra
hassle since it contains some site specific configuration.

Modified Sat Oct 1 01:17:24 2005 UTC (8 years, 6 months ago) by dpvc
Original Path: trunk
Major update to allow ImplicitPlane objects to be created
automatically by the Parser when it sees equal signs.  This makes it
possible to use ImplicitPlanes in Lists.  (Before, when the List was
turned into a Formula returning a List, the equality became a plane
old equality rather than an ImplicitPlane object.)

This is a bit of a hack for now until I can make List and other Value
objects be allowed to have Formulas as their entries rather than turn
into Formulas returning Lists (or whatever type).

Revision 3678 - Directory Listing
Modified Sat Oct 1 01:13:27 2005 UTC (8 years, 6 months ago) by dpvc
Original Path: trunk
Handle the names of entries in Lists and Formulas returning lists
better.  Also do better typechecking on these lists.  Finally, allow
better typechecking for String objects that are being used when a
Formula answer is allowed.

Revision 3677 - Directory Listing
Modified Sat Oct 1 01:10:27 2005 UTC (8 years, 6 months ago) by dpvc
Original Path: trunk
Allow context to override object class used to create formula objects
(so that things like ImplicitPlane can create instances of themselves
automatically when needed).

This mechanism needs to be enlarged to encompass the other Value
object classes as well (like the Context()->{parser}{...} hash).

The real problem is that the List object probably shouldn't create a
formula returning a list when it is passed formulas, since there
really isn't much need for a formula returning a list to be
autogenerated (you can create one by hand using Formula if needed).

Right now, ALL the Value objects make themselves into Formulas when
one of their entries is a formula.  For example, Point(1,"x") produces
the same thing as Formula("(1,x)"), and List(1,"x") is the same as
Formula("1,x").  This is good for points, but not so good for lists.
And it might sometimes be nice to have a Vector of Formulas, or a
Matrix with Formula entries (rather than Formulas returning Vectors or
Matrices).  But this would require some serious changes internally in
the Value objects, which make assumptions about their values being
constant.  Changing that will be for another day...

* a.k.a. operations, privilegespermissions, gotta get the terminology
straight. think of the users!

%userRoles should be used by modules such as UserList for providing more
intelligent editing of the permission_level field. Another possible use
would be to for pretty-printing user types -- a user could be called a
student, ta, professor, etc. based on what role corresponded to their
permission_level.

Simplified the interface for users (who can only download one set at a time and can only download one user).
It could be made slightly more general -- it currently implicitly assumes that either one can edit both
multiple sets and multiple users or one can edit only a single user and a single set.

Removed an error in the [edit] link when there is an error.  The anchor HTML tags were wrapped two layers deep
around the reference.

Can probably still use some more tweaks in the interface.

Updated to be able to handle empty anwswer blanks.  There is a new
parameter for the MultiPart object (allowBlankAnswers) that controls
whether the checker routine will be called even when there are blank
entries (normally, the checker is not called unless all the entries
are non-blank).  Use

  $mp = MultiPart(1,2)->with(checkTypes=>0,allowBlankAnswers=>0);

to have the checker routine called when answers are left blank.

You can now also include blank answers in the list itself:

  $mp = MultiPart(1,2,"");

(there is no need to include allowBlankAnswers in this case, because
the blank string will take care of itself.

Extensive refactor/rewrite.

There are probably going to be bugs here that we squished in the old
version of Hardcopy, but it seems to be pretty robust after an evening
of testing. Alert me if you see problems.

Features:

* standard ScrollingRecordLists are used for user and set selection.
* TeX source is written incrementally instead of being accumulated in
  memory.
* arguments to shell commands are now quoted using String::ShellQuote
* modular design allows adding additional formats easily (i.e. dvi, ps)
* error reporting code is simplified.
* if errors/warnings occur, user will see them on screen instead of
  getting the hardcopy file.
* on the error screen, user can click to get (possibly broken) hardcopy
  if it exists.
* on the error screen, user can click to get interesting temporary
  files. (for PDF format these are hardcopy.{tex,log,aux} and
  pdflatex.std{out,err}.)
* on the error screen, if an error concerns a particular problem, an
  "edit problem" link is included.
* probably more stuff i'm forgetting

Bring jsMath up to version 2.1d, which fixes a number of small bugs,
including:

  o There was a problem with image fonts where the cached data about
    the size of the images was not being checked properly, so was
    recomputed every time a character was displayed. The cache is now
    properly handled, so that should speed up image mode.

  o Fixed a bug where loading extra fonts while in image mode would
    cause the data about previously loaded image fonts to be lost.

  o Fixed a bug with "Hi-Res Fonts for Printing" where the fonts where
    incorrectly scaled so that they appear far too small. (This worked
    in an early beta version of jsMath v2, but apparently hasn't
    worked properly in any production version.)

  o Fixed a long-standing bug where horizontal lines are only
    displayed in black, not in the color specified by \color (or by a
    style from the surrounding text).

  o Fixed a similar bug with \rule so that it now produces a box with
    the color of the surrounding text.

  o Dimensions can now be enclosed in braces (for example, \rule can
    be \rule{10pt}{5pt}{3pt} as well as \rule 10pt 5pt 3pt).

Added support for cplx_cmp() using the Parser.  Move
lib/Parser/Legacy/PGcomplexmacros.pl to the pg/macros directory to use
it.  As with the other legacy macros, $useOldAnswerMacros can be
controlled to determine whether the new or the old macros are used.

There is a new mode 'strict_cartesian' that is parallel to
'strict_polar'.  You must enter a+bi form, but the a and b can have
operations within them.

Added "strict" versions of the limited complex contexts that don't
allow operations within the real and imaginary parts.  Also cleaned up
some of the code and fixed a few situations that had been missed
before.

Note that in strict mode, e^(pi i) is accepted, but e^(pi/2 i) is
not.  Should that be changed?  It would be possible to make a context
in which a*e^(b*pi/c i) is accepted.

Original Path: trunk
Movified the copying of functions from Complex1:: into main:: to avoid
conflicts with the PGcommonFunctions.pl versions (these errors were
trapped, but still show up in the error log unnecessarily).

Also commented out some code that was not doing anything other than
producing error messages in the error log.  (It was left over from a
syntax check on the professor's answer, but the actual check was
removed, leaving a portion that tries to process the answer, but
usually fails (because things like "1+4i" need to be converted to
"1+4*i" before they can be used in PG_answer_eval, but that was not
being done).

Because of this, it is not possible currently to do cplx_cmp("1+4i"),
and instead you must to cplx_cmp(new Complex(1,4)).

To fix this, you would need to call check_syntax (and the other
filters that are called on the student's answer) before calling
PG_answer_eval.  Of course, you should only do this when the
professor's answer isn't already a Complex object.

I am going to work on a Legacy module like the ones for num_cmp and
fun_cmp to replace cplx_cmp, which should avoid these problems and
make the changes suggested above unnecessary.

The perl method for UOP and BOP now put spaces around the operator, to

*Parser::Function->call is a name reference.  (Some of these had been
done by hand earlier, but now the base BOP and UOP classes handle it,
so we should not have problems in the future).  I removed the ad hoc
fixes from several other locations (Parser/Function.pm,
Parser/Context/Default.pm).

Also extended the operator definitions to allow operators to create
function-call syntax in perl mode (for when the operator doesn't
correspond to a perl operator).

You need to be VERY careful when doing this, as this will affect ALL
problems that use the Parser.  Your changes may cause some .pg files
to fail if they rely on the default behavior that you are changing.

If you wish to override settings in one of the predefined contexts
(like "Vector"), then define $context{Vector} as a copy of
$Parser::Context::Default::context{Vector}, as in the commented out
examples.  Then Context("Vector") will use your copy rather than the
original.  If you were to change the version in
Parser::Context::Default, that would change the parser for ALL
courses, not just yours.

Original Path: trunk
Allow use of an activity log which logs every click, stored on a
per-course basis.  It is turned off by default.  It can be turned
on/off for individual courses.  The three pieces here:

  global.conf.dist: adds a place to define the log file.  Here an
    empty value signals to not do this logging.

  ContentGenerator.pm: check to see if the log file is defined (and
    (non-trivial), and if so, write a log entry.  We check if it is
    defined at this point to both save some time, and because if we
    get to writeCourseLog and the log isn't defined, we get a pink
    screen.

    The bulk of the text of the log entry is performed by a new method
    prepare_activity_entry.  By default, this gives the url, and a list
    of all the cgi parameters (except for key and passwd).  This method
    can be overridden by individual modules.  The default format may
    change.  It may take some fine tuning to see what is best.

    Also, this is one of the first functions called by go.  We may want
    it to go after the action has taken place if we want instructor
    modules to be able to report results of their work through this log.

  SetMaker.pm: gives an example of overriding prepare_activity_entry.
    SetMaker has lots (and lots and lots) of data stored in cgi
    parameters.  We probably don't want to log that.  We might want to
    log a little more in SetMaker than we do here (target set), but
    this gives a start.

Original Path: trunk
Fixed problem with Context's not properly initializing themselves with
the WW environment parameters (like zeroLevelTol and useBaseTenLog).
The copy method and the method that did an initialized copy used to be
separate routines, but that turned out to be unnecessary, so they have
now been merged (copy always tries to initialize the WW values when it
can, and when the copied context doesn't already have them).

The reason this is complicated is that a number contexts are set up
before the global.conf data is available, so these can't be
initialized with the WW values.  Also, these default contexts are
stored in the persistant processes, and we don't want to leave
possibly course-specific values lying around in them, so whenever a
context is selected, it is copied from the standard version and the
WW parameters are inserted into it.  The problem author can only
modify the copy, not the original, so this is OK with mod_perl.

The context's copy method now always tries to initialize (we used to
have to call initCoopy to get a copy that has the WW parameters
inserted).  That turned out to cause trouble with code that handled
contexts without the usual Context() command.

available from within this preloaded package.  The in- and outside
the safe compartment stuff is very confusing, and functions that are
not overloaded native perl functions seem to be not callable from the
Value::Formula package, so the perl method now calls
Parser::Function->call() directly (doesn't look pretty, but I've given
up on that).

Modified Sun Aug 14 16:52:11 2005 UTC (8 years, 8 months ago) by gage
Original Path: trunk
Add the beginnings of a facility for archiving a course.  This method uses mysqldump
and therefore will work only with a mysql database.  Many things are still hardwired
In particular mysqldump is hardwired.
The database name is hardwired to  "webwork"

Archiving consists of dumping the tables associated to the course to a file
$courseID/DATA/$courseID_mysql.database  (this file can be used
to created a new database for the course.  it will not overwrite existing
tables however.)

Then the entire course directory is tarred and gzipped and placed
in the courses directory with the naem $courseID.tar.gz

Currently nothing is deleted from the database and no directories are deleted.
So the implementation is fairly safe, but not yet very useful for course management.

There is not yet a facility for automatically importing the archived course.

Added methods for testing containment of one set in another, and so
on.  These include:

     $A->contains($B)        Test if $B is a subset of $A (or an
                             element of $A if $B$ is a real number).

     $A->isSubsetOf($B)      Test if $A is a subset of $B.

     $A->isEmpty             True if $A is the empty set.

     $A->intersects($B)      True if $A and $B have numbers in common.

     $A->intersect($B)       The set of numbers common to both $A and $B.

Be careful of the difference between "intersect" and "intersects".
One is a set the other a true/false value.

Revision 3524 - Directory Listing
Modified Sun Aug 14 00:18:46 2005 UTC (8 years, 8 months ago) by dpvc
Original Path: trunk
Added a copy method that produces a deep copy of the given object.
This probably should be used through the new() methods to ducplicate
the data used when creating an object, otherwise changes to the
sub-objects will cause changes to the outer one.  For example, if an
interval is used to create a union and then the internal data for the
interval is changed by hand, the changes will also occur in the
union.  That is, Value objects contain their data by REFERENCE.  This
should probably be changed, but fortunately, no one should be
adjusting the internal structure of the objects by hand.

Improved the message facilities for the list comparison so that
cmp_compare can make errors that refer to the number of the entry in

Revision 3497 - Directory Listing
Modified Sat Aug 13 00:25:27 2005 UTC (8 years, 8 months ago) by dpvc
Original Path: trunk
Added ability for Unions and Sets to simplify themselves
(automatically or on demand), and added flags to the Context and
answer checkers to control these features.  The new Context flags
are

    reduceUnions                tells whether unions are automatically
                                reduced when they are created.

    reduceUnionsForComparison   tells whether unions are reduced
                                before comparing them for equality
                                or inequality (etc) if they aren't
                                reduced already.

    reduceSets                  tells whether redundent elements are
                                removed from sets as they are created.

    reduceSetsForComparison     tells whether sets are reduced before
                                comparing them.

All of these default to true.

The Interval, Set, Union, and List answer checkers not have two new
flags for controlling these values:

    studentsMustReduceUnions    tells whether unions and sets will be
                                counted as incorrect when they are not
                                reduced to non-overlapping intervals
                                and at most one set with no repeated
                                entries.

    showUnionReduceWarnings     tells whether an error message will
                                be produced for non-reduced unions and
                                sets, or if they will be marked wrong
                                silently.  (Not available in Lists.)

Both of these are true by default, since most professors probably want
their students to write intervals in reduced form.  (Is this true?)
This corresponds the the current behavior of the interval checkers,
which require the student's answer to be the same set of intervals as
in the professor's, but with the addition of an error message when the
student answer is not reduced.

Modified Fri Aug 12 01:21:48 2005 UTC (8 years, 8 months ago) by dpvc
Original Path: trunk
Added redefine() function to complement undefine() for various
Context() values.  For example

      Context()->operators->undefine('+');

makes '+' undefined, but

      Context()->operators->redefine('+');

will put it back.  You can specify a context from which to take the
redefinition, and a name in that context, as in

      Context()->operators->redefine('U',from=>"Interval");
      Context()->operators->redefine('u',from=>"Interval",using=>"U");
      Context()->operators->redefine('U',from=>$content);

where $content is a reference to a Context object.

The undefine() function lets you undefine several items at once, as in

      Context()->operators->undefine('+','-');

For redefine, you must put multiple names in square brackets because
of the optional parmeters:

      Context()->operators->redefine(['+','-']);

improvements to view options.

removed default options() implementation and helper function
viewOptions(), and added more modular optionsMacro() method, which is
intended to be called from content generators which require an options
panel.

POD for optionsHelper():

=item optionsMacro(options_to_show => \@options_to_show, extra_params =>
\@extra_params)

Helper macro for displaying the View Options panel.

@options_to_show lists the options to show, from among this list
"displayMode", "showOldAnswers", "showHints", "showSolutions". If no
options are given, "displayMode" is assumed.

@extraParams is dereferenced and passed to the hidden_fields() method.
Use this to preserve state from the content generator calling
optionsMacro().

This macro is intended to be called from an implementation of the
options() method. The simplest way to to this is:

 sub options { shift->optionsMacro }

=cut

rather than the previous (1,5) U ((7,10) - {8}) U (2,3).  Finally,
added a constant 'R' to the Interval context that is equivalent to
(-inf,inf), so you can do things like R-{0} now.

Still need to work out reducing unions so that things like (1,3)U(2,4)
can become (1,4).

Added new Set object class to the Parser.  It implements a finite set
of real numbers, for use with unions and intervals.  E.g., (1,2) U {3}
or (1,2) U {3,4,5}.  You can created Set objects in your perl code via
the Set() command, e.g, Set(3,4,5) or Set("{1,2,3}").  You should set
the Context to Context("Interval") if you plan to use Set objects, as
this defined the braces to form sets (rather than using them as
parentheses, which is the default WW behavior).  Note that in Interval
context, you can NOT use braces as parentheses.

Current, Set objects are only allowed to be sets of numbers.  It would
be possible to extend that in the future.

fixed indentation (see crabby reminder below).

The code I just fixed was using four spaces for one level of indentation
and a tab character for two levels of indentation. apparently, this is a
variation on the "use spaces for indentation" philosophy that also
replaces any run of eight spaces with a tab. this is NOT the way we've
been doing things in webwork, and consistency is important (I think).

===> the webwork indentation policy <===

We use the TAB character to indicate a level of indentation, and SPACE
characters to line things up in lists. I understand there is some debate
as to whether is it appropriate to use "hard" tabs in text files. We do
it because some of the WeBWorK developers prefer to view the code with
wider indentation (say, eight columns) and some prefer narrower
indentation (say, three or four columns). Thus, we use hard tabs for
initial indentation and let each developer chose a tab width using their
editor.

Here in an example of when to use tabs and spaces. ---> represents a tab
character.

my %errors = (
--->not_found            => "The record was not found.",
--->invalid_id           => "The record ID is invalid.",
--->undefined_or_unknown => "The record was undefined or unknown.",
);

sub bar {
--->my ($self, @recs) = @_;
--->foreach my $rec (@recs) {
--->--->my $Rec = $self->getRec($rec);
--->--->if ($Rec->error) {
--->--->--->warn $errors{$Rec->error};
--->--->} else {
--->--->--->foo($Rec->a, $Rec->b);
--->--->--->baz(
--->--->--->--->origin             => $Rec->origin,
--->--->--->--->destination        => $Rec->destination,
--->--->--->--->widgets_per_second => $Rec->widgets_per_second,
--->--->--->--->score              => $Rec->score,
--->--->--->--->email_address      => $Rec->email_address,
--->--->--->);
--->--->}
--->}
}

As you can see, indentation that is used to "line up" elements on
adjacent lines uses spaces, while indentation that is used to indicate
some structural heirarchy in the code uses tabs.

I've changed errorOutput($error,$details) to accept a reference to a string
or to an array for $details.  These are automatically converted to the proper form.
References should be used when the $details points to a large number of bytes, such
as the contents of a file.

This version is not faster than the original method where $details was always a
string, sometimes a very long string.  It does seem to save memory however.

Further savings in memory could be obtained by print directly, but there are a few instances
which call errorOutput and then do further formatting before printing.

At the moment it doesn't seem to be worth it to make the change from return to print.

Backing out of the changes just made for a moment.  I've discovered that making this switch:

CGI::p(CGI::code($details)),

to

CGI::code(CGI::p($details)),

speeds things up immensly.  (From 165 seconds down to 12 seconds on the example I'm doing.)

Even without any other changes. Since the other changes complicate things a bit, I'll put
off adding the ability to have $details be a reference.

It's possible that allowing $details to be passed as a reference is a good idea anyway,
on general principles.  I want first to see if it makes a difference in terms of memory
consumption.

Original Path: trunk
Fix use of $SIG{__WARN__} and $SIG{__DIE__}.

* Each change to $SIG{__WARN__} and $SIG{__DIE__} is now dynamically
scoped with "local", rather than changing globally and then restoring at
the end of the block.

* The special value "DEFAULT" is used instead of sub {CORE::die(@_)} or
sub {CORE::warn(@_)} when preparing to eval STRING code.

* Where $SIG{__WARN__} and $SIG{__DIE__} are overridden to do
preprocessing with PG_errorMessage, the previously installed handlers
will be called instead of the built-in warn or die functions after
preprocessing occurs. (For example, the warn and die handlers defined in
Apache::WeBWorK or the warn handler defined in WeBWorK::PG will be
called.)

* The behavior in process_answers is modified so that the custom
handlers are installed once before the answer evaluation loop. This
causes them to be in effect during the setup/teardown code, but I don't
think this will be a problem.

Add command-line utility to update sql and sql_single databases to include
gateway fields.  Use: wwdb_addgw [-h] [sql|sql_single]

Adds fields to the set and set_user tables in the WeBWorK mysql databases
that are required for the gateway module.  The script prompts for which
courses to modify.  Adding gateway database fields to existing courses
should have no effect on those courses, even if they are running under a
non-gateway aware version of the WeBWorK system.  (I haven't rigorously
tested this.)

If -h is supplied, the script hides the mysql password when it prompts for
it (this assumes that a Unix based stty -echo works).  If sql or sql_single
are supplied, they become the default database format.

Note that this has been tested, but not rigorously.  Please let me know
if you find that it does not perform as advertised.  It might be wise to
back up the database tables before using, and to check that it does what
we expect (that is, adds columns to the set and set_user tables) after
running it.

Original Path: trunk
Preliminary commit of changes to add Gateway module.
This adds to WeBWorK
 - the ability to create versioned, timed problem sets ("gateway tests")
   for which all problems are displayed on a single page ("versioned"
   means that students can get multiple versions of the problem set),
 - the ability to create sets that draw problems from groups of
   problems, and
 - the ability to create sets that require a proctor login to start
   and grade.
Sets can be defined as gateway tests or proctored gateway tests from
the ProblemSetDetail page.

Not quite bug-free yet.  Known bugs include handling of problem values
on the Student Progress page (I think this may be a problem with
changing from sql database format where all entries were 'text' to
sql_single in ver 2.1, where they are integer), and a division by zero
error on the grades page (which may be the same problem).

Tests with a number of attempts per version greater than one haven't
been carefully tested, nor has scoring of gateway tests.

Revision 3370 - Directory Listing

Original Path: trunk
A first pass at making parser error messages localizable.  The
Context()->{error}{msg} hash can be used to specify translations of
the standard messages.  For example,

    Context()->{error}{msg}{'Division by zero'} = "Don't divide by zero, dude!";
    Context()->{error}{msg}{'Function '%s' has too many inputs'} =
        "You passed too many arguments to '%s'";

(I didn't translate into another language, here, but you could do
that, too.)

The msg hash could also be used within answer checkers to make certain
answer messages more appropriate for the given type of expected answer.

it work better from within packages or when Parser.pl hasn't been

A few things still won't work in this case; e.g., calls to Closed()
for intervals (these could be handled better using ->with()) and to
functions like Factorial and log10 that are defined in Parser.pl.

Finally, there should be better object-based control over what
routines are called to create these objects, so that subclasses of the
Value objects will be able to be generated correctly.

This is an attempt at making the traditional answer checkers call the

instead of the original PGanswermacros.pl versions.

The old answer checkers are still available, and can be switched back
on a site-wide, course-wide, or problem-by-problem basis.  See the

the filters.

Revision 3330 - Directory Listing
Modified Sat Jul 2 16:52:31 2005 UTC (8 years, 9 months ago) by dpvc
Original Path: trunk
Major updates to the file manager to allow it to:

1.  Show dates and sizes of files (optionally, since some browsers
    don't handle the CSS to change to a monospaced font).

2.  Provide better control over renaming of uploaded files whose
    names already exist (there is a checkbox for overwriting them
    automatically; if unchecked, the user is prompted for a new name).

3.  Allow the creation or gzipped tar archives from files in the
    course directory.  Multiple files and directories can be selected
    to be included in the archive.  If only one file is selected, the
    archive will have it's name with ".tgz" appended; if mulitple
    files are selected, the archive will get a unique name starting
    with the course ID.

4.  Provide a checkbox that controls whether uploaded .tgz archives
    are unpacked automatically, and a second that controls whether the
    unpacked archive file is deleted afterward.  Files from the
    archive will be unpacked into the current directory, and will
    overwrite existing files silently.

5.  Follow symbolic links that are to files or directories within the
    course hierarchy.  In addition, there is a new variable in
    global.conf that provides a list of "valid links"; these are
    directories to which the FileManager is allowed to follow symbolic
    links.  The system administator can add directories to this list
    in order to allow professors to access limited areas outside their
    course directory (but they still need to have a symblic link
    within their course to those areas in order to view them).

I think this covers all the current FileManager requests, and this
closes bug#791.

Fixed conceptual error in compare_vec_solution.  This should fix bug
#670.  In my opinion the entire concept of vec_solution_cmp should be
reconsidered.  In solving an underdetermined linear equation of the form
Ax-b=0 it seems to me that the solutions answer in the form:
x= a +bt+cu+ds  where a,b,c,d are vectors should simply be evaluated
to see if it satisfies Ax-b=0 for 5 or six values of a,b,c,d  --
checking the solution should use a
vector valued version of fun_cmp.

As it is, the student's coefficients for a,b,c,d are compared with the
instructors to see if they span the same space. This is quite a bit more
complicated -- and indeed the method came up with the wrong answer.

I believe I have the method corrected, but I would suggest that this
answer evaluator be replaced with one which operates more
directly and is therefore easier to maintain.  Am I missing something in
this analysis?  Has someone else created answer evaluators for this type
of problem?

variable are allowed to be entered (though the coefficients can
contain mathematical operations).  An optional flag lets you specify
that only one term of each degree is allowed, so the student would

Forgot to check hardcopy mode.  Fixed some problems with that.  The
answer array items have to turn off verbatim mode that is used when
answer are included in the hardcopy.  This causes paragraph breaks
between entries in a singleResult MultiPart that includes ans_arrays,
which make the output less pretty, but at least they show up.

Original Path: trunk
Added styles to make Parser's ans_array methods show up properly in
the student answer and correct answer blocks.

The style for the td in the results table causes havoc for tables that
are nested in there.  This solves is for Parser produced answer
arrays, but it is still messed up for the standard ans_array() and for
the output of tth (the formatted text option).

The way the style for this table is handled should probably be
changed.  Perhaps if we could override for td's in tables nested in
the results area?  I don't know enough about CSS to figure that out.

Revision 3270 - Directory Listing
Modified Mon Jun 6 00:01:44 2005 UTC (8 years, 10 months ago) by dpvc
Original Path: trunk
This file implements a Multi-Part parser object that allows you to tie
several input blanks to a single answer checker that can compare the
student's answers in several blanks in order to determine which are
correct.

For example:

      $mp = MultiPart("x^2",1,-1)->with(
        singleResult => 1,
        checker => sub {
          my ($correct,$student,$self) = @_;  # get the parameters
          my ($f,$x1,$x2) = @{$student};      # extract the student answers
          Value::Error("Function can't be the identity") if ($f == 'x');
          Value::Error("Function can't be constant") if ($f->isConstant);
          return $f->eval(x=>$x1) == $f->eval(x=>$x2);
        },
      );
           .
      BEGIN_TEXT
        \(f(x)\) = \{$mp->ans_rule(20)\} produces the same value
        at \(x\) = \{$mp->ans_rule(10)\} as it does at \(x\) = \{$mp->ans_rule(10)\}.
      END_TEXT

      ANS($mp->cmp);

This produces three answer blanks all tied to the same checker, which
is supplied by the user when the MultiPart is specified.  This one
checks if two inputs to a function provide the same output.

The answer blanks can each produce a separate row in the results area
at the top of the page, or they con be combined into a single row, as
in this case.  The checker routine can provide error messages for
individual parts via the setMessage() method, or for the problem as a
whole, as above.  Finally, the ans_array() method can be used to
produce answer blanks for individual entries for those objects that
support such arrays.

See the documentation at the top of the file for additional details.

Revision 3269 - Directory Listing
Modified Sun Jun 5 23:52:11 2005 UTC (8 years, 10 months ago) by dpvc
Original Path: trunk
Added ability to have Matrix, Vector and Point objects produce input
arrays similar to the ones available in PGmatrixmacros.pg.  This
provides some substantial new functionality, and it may still have
some shaking down to do, but it should not affect the existing
functionality of the answer checkers.

To create an answer array for a matrix, vector or point, use the new
ans_array() or named_ans_array() methods of these objects.  For
example:

	Context("Matrix");
	$M = Matrix([1,2],[3,4]);

	BEGIN_TEXT
	\{$M->TeX\} = \{$M->ans_array\}
	END_TEXT

	ANS($M->cmp);

This creates a matrix, then prints it ans creates an answer array of
the appropriate size for the matrix.  The answer checker will
automatically know to handle the multiple entry blanks.

To used a named answer rule, use:

	Context("Matrix");
	$M = Matrix([1,2],[3,4]);

	BEGIN_TEXT
	\{$M->TeX\} = \{$M->named_ans_array('fred')\}
	END_TEXT

	NAMED_ANS(fred => $M->cmp);

Both methods also take an optional argument that specifies the width
of the answer rules.  The default is 5.

You can get a multi-input point or vector array as well, and you can
make column vectors as follows:

        Context("Vector");
	$V = ColumnVector("1+x","3x","1-x");

	BEGIN_TEXT
	\{$V->TeX\} = \{$V->ans_array\}
	END_TEXT

	ANS($V->cmp);

Note that you can make answer arrays for matrices and vectors of
formulas as well as constants, provided the formula is an explicit
matrix or vector of formulas, and is not obtained by matrix
arithmatic.

For concistencey, all objets now have ans_rule and named_ans_rule
methods as well.  The default width is 20 for these.

Better control over number of points that can be undefined, and
new ability to specify required test points plus additional random
ones.  (Previously, if you set the test points, no random points were
generated.)  For example:

     $f = Formula("(x^2-1)/(x-1)");
     $f->{test_at} = [[1]];  # test at x=1 plus random points

as opposed to

     $f->{test_points} = [[-1],[0],[1]];

which tests only the points x = -1, x = 0 and x = 1.

Revision 3257 - Directory Listing
Modified Thu Jun 2 22:50:24 2005 UTC (8 years, 10 months ago) by dpvc
Original Path: trunk
Modified the Formula answer checker to allow checking of points where
the functions are undefined (i.e., attempt to check that the domains
agree).  This can be enabled by setting the checkundefinedPoints flag
in the Context(), or in the formula itself.  Test points where the
function is undefined will be retained and the student's answer will
have to be undefined at the same points.  If the points are selected
at random, the points where the function is undefined are kept in
addition to the ones where it is defined, so the required number of
test points where the function IS defined will still need to be
found.  The number of undefined points can be up to the number of
defined points.  This number can be reduced by setting the
max_undefined flag.  If you want to guarantee that a specific
undefined point be tested, you can provide that point using the
test_points field of the formula.  For example:

     Context()->flags->set(checkUndefinedPoints=>1);
     $f = Formula("(x^2-1)/(x-1)");
     $f->{test_points} = [[-1],[0],[1],[2]];
     ANS($f->cmp);

will guarantee that the singularity at x=1 is tested, so the answer
x+1 will not be marked as correct.

If an answer matches at all the test points where the functions are
both defined, but some of the undefind points differ between the two
functions, the answer checker will generate an error message
indicating that the domains of the functions don't agree.  (This is
ONLY generated with the functions match except for that.)  This can be
controlled by setting the showDomainErrors flag in the formula's cmp()
call:

     ANS($f->cmp(showDomainErrors=>0));

The default is to show these errors.

This makes it possible to store special macros files with the code

By default, the path is ".", the course/templates/macro directory,
then the pg/macros directory (in that order).  This duplicates the
current behaviour, except for the ".", which is new.

Providing an initial fix for bug 784.  I'd like to
continue to work on this module and factor out some of

For now this hack (which involves splitting

and used for two different purposes) should work.

Revision 3208 - Directory Listing
Modified Tue Mar 29 19:16:36 2005 UTC (9 years ago) by dpvc
Original Path: trunk
Provide an easy means of generating a custom answer checker based on
an user-supplied subroutine.  Most of the work is done by the Parser's
answer checker framework, and the user's routine is called at the
point that the student's answer is compared to the correct answer.

Revision 3207 - Directory Listing
Modified Tue Mar 29 13:14:17 2005 UTC (9 years ago) by dpvc
Original Path: trunk
Handle error messages in the list checker better.  In particular, make
the error messages generated by custom checkers called on elements in
the list look better.  Also, in an ordered list, if the student enters
extra values, call an answer checker to do a syntax check.  (By
default, use the first element again, but the user can supply a
separate object to use for the checker using the extra=>object
option.)

Revision 3206 - Directory Listing
Modified Tue Mar 29 03:25:29 2005 UTC (9 years ago) by dpvc
Original Path: trunk
Compartmentalize the equality check one step further.  The cmp_equal
method now calls a new cmp_compare method to perform the actual
comparison (rather than use == directly).  The cmp_compare method
either calls a user-supplied checker routine, or defaults to using the
== operator.  The list checker also uses cmp_compare to check the
individual items in the list.  The list checker also calls a new
cmp_list_checker method to perform the list check.  This can be
overridden by a user-supplied list-checking routine.

To supply an alternate checking routine, use the "checker" option to
the cmp() method of the correct answer object.  For example:

    sub check {
      my ($correct,$student,$ans) = @_;
      return 0 unless $correct->length == $student->length;
      my ($x,$y) = $student->value;  # break up a point;
      return $x**2 - $y**2 = 1;      # check if it is on a hyperbola
    }
    Point(1,0)->cmp(checker=>~~&check);

This will check if the student's point lies on the given hyperbola.  All
the usual error messages will be issued if the student's answer is not
a point, or is of the wrong dimension, etc.

You can use

    sub list_check {
      my ($correct,$student,$ans) = @_;
      my @correct = @{$correct}; my @student = @{$student};
      ...
      return ($score,@errors);
    }
    List(...)->cmp(list_checker=>~~&list_check);

to replace the list-checking routine with your own custom one.  The
$correct and $student values are array references to the elements in
the lists provided by the professor and student.  (Note that you do
NOT get a List() object; this allows you to handle lists of formulas,
since a List of formulas becomes a formula returning a list).  The
checker routine should return the number of correct elements in the
student's list ($score), and a list of error messages produced while
checking the two lists (@errors).  (This is a list of messages, since
you might want to include an error for each entry in the list, for
example).

If your checker or list_checker routine wants to die with an error
message, use Value::Error(message).  This will put the message in the
WeBWorK display area at the top of the page.  If you use die(message),
or if the code fails due to a runtime error, then "pink screen of
death" will be produced indicating the error and asking the student to
report the error to the professor.

Update the overloaded operators so that they can be overridden by
subclasses of the predefined object classes.  This involves calling
the objects method rather than using a hard reference to the routine
in the parent class.

Also, change the name of the string comparison routine to
compare_string to avoid conflicts with cmp that is used to produce the
answer checker for the class.

Finally, in Value.pm, promotePrecedence no longer has to do fancy
footwork to get "special" precedence to work (this was a hack to get
around the misfeature of the overloaded operators -- now that that is
being handled correctly, there is no need for it).

Revision 3172 - Directory Listing
Modified Tue Feb 15 21:58:54 2005 UTC (9 years, 2 months ago) by dpvc
Original Path: trunk
Updated the answer checkers so that you can more easily specify how
the correct answer shoudl be displayed.  In the past, you could use
something like Real(sqrt(2))->cmp(correct_ans=>"sqrt(2)") to do this,
but that is awkward.  Now the Compute() function (which parses and
then evaluates a string) sets things up so that the original string
will be what is used as the correct answer.  That means
Compute("sqrt(2)")->cmp will have the same result as the example
above.

You can also set the {correct_ans} properly of any Parser object to
have that value used as the correct answer.  For example

     $x = Real(sqrt(2));
     $x->{correct_ans} = "sqrt(2)";
     ANS($x->cmp)

would also produce the same answer checker as the two previous
examples.  All three methods should work.  Use the one that is most
convenient for you.

Improved the Real(), Complex(), Point(), Vector(), Matrix() and
String() constructors so that they will process formulas passed to
them as strings rather than requiring perl objects for these.

want.  Also, Real("1+x") will return a formula returning a real
(essentially the same as Formula("1+x") in this case).

I believe this will fix the bug which sometimes causes multiple users
to appear in the parameters.  The problem is that Login.pm filters out
user, key, passwd  values and then passes the remaining values to
hidden_fields to be printed on the "relogin" page.  Unfortunately if
hidden_fields is passed an empty array then it prints ALL values in the
parameter hash as hidden fields.  So if only user and key are present
they will be printed as hidden fields.  If user, key and a non-filtered
paramter value are present then only the non-filtered parameter value
will be printed.

The current fix is a conditional which doesn't call hidden_fields at all
if there are no parameters left after the filtering operation.
