Since the CGI debug scripts are programmatically generated, they have
been removed from the distribution. To re-create them, run the script
MAKEDEBUG from this directory:

	$ cd webwork/system/cgi

cgi-bin directory.

Removed leftover PGanswermacros.pl.original

Removed MAKELINKS.PL and MAKELINKS.pl, and replaced them with a script
called MAKELINKS, which can take the path to the PG directory on the
command line:

NAME
    MAKELINKS - create symlinks pointing to the contents of the pg/lib and
    pg/macros directories for use in the WeBWorK 1.x courseScripts
    directory.

SYNOPSIS
     ./MAKELINKS [pg_dir]

DESCRIPTION
    MAKELINKS takes a single argument, the path to a pg directory,
    containing lib and macros directories. If no arguments are given, a
    default of ../../../pg is used.

    Given this inforamtion, it creates symlinks in the current directory
    pointing to each "*.pl" file in the macros directory and each "*.pm"
    file and directory in the lib directory.

Fixed bug in filehandles for output.  Why this worked on freeBSD I don't
know but it hung jobs on Red Hat.  By default output still goes to STDERR.
I don't know a good way to send to a set file independent of how the system
is set up since relative paths don't work (they send output to 2 files).

Revision 1417 - Directory Listing
Modified Wed Jul 23 14:38:21 2003 UTC (10 years, 8 months ago) by apizer
1. Fix bug in line 547 (added: if $main::timingON) so that script runs even
if $main::timingON is set to 0.

2. Set $main::timingON=0; in distributed script

3. Bugs remain (at least in Red Hat). If the error.log file is not specified,
getting hard copy just hangs. If it is specified, hardcopy works but the timing info
is not entered into the log file.

Revision 1366 - Directory Listing
Modified Fri Jul 11 20:30:31 2003 UTC (10 years, 9 months ago) by lr003k
In order to make ans_array entries "sticky" I've had to change some stuff.
The answer labels for these entries are now put into
$main::PG_FLAGS{ANSWER_ENTRY_ORDER} as an array reference in PG.pl.
In processProblem8.pl the labels are caught again in the subroutines
logCourseData and encode_submitted_answers. It is important that
they're caught there rather than earlier because then the translator would
think that every entry was it's own answer.
Professor Gage says that processProblem8.pl is no longer used in webwork2, and
he says he'll fix this there.

Added some lines to the defineProblemEnv routine.  The variables used by HTML_img and HTML_dpng are too
close for comfort. But it works for now.  What doesn't work is that when tex is called it produces
output which spills over and is returned to the CGI call -- leading to an internal error.  The forking
code in welcomeAction.pl fixes this problem.  Perhaps there is a simpler way.

	$envir{'externalLaTeXPath'}   		=	$Global::externalLatexPath;  #used by HTML_img

Added dvipng subroutine.  Corrected some errors in math2image.  dvipng
is still not being called correctly -- I think math2image needs more
updates.

dvipng is also in IO.pm, but making this available to WeBWorK1.8 seems
like a lot of work, hence I've only made a copy of the dvipng subroutine
from IO.pm.  With luck this will not interfere with WeBWork2.0.  I'm
open to suggestions for a better way to make both dvipng methods
available to both WeBWorK2.0 and WeBWorK 1.8

Added the preprocessing facility.

The current default preprocessor is a filter which takes the initial PG problem
and handles the BEGIN_TEXT/END_TEXT blocks as well as escaping backslashes and
replacing ~~ by backslash.

Other preprocessors can be installed to effect different behavior.

At present there is only one preprocessor.  The behavior of the method
preprocess could be modified to allow a chain of preprocessing filters
if that becomes desirable.

The barest bones of a postprocessing facility is also in place.  The
current default postprocessor does nothing.  This could be implemented
to create sticky answers.

Fixed bug in PGcomplexmacros.pl having to do with the lack of a
=cut line in the pod documentation.

The loadMacros eval doesn't fail gracefully when this kind of mistake
occurs.  More work needs to be done on loadMacros.

Also changed the _PGcomplexmacros_init subroutine to include the
exporting of variables from Complex.

I think this is what it was supposed to do in any case, but perhaps not.
When using the forking process it was only necessary to export the
variables in the parent.

Added documentation and _PG....macros_int functions to these files.

In PGcomplexmacros.pl I removed the automatic exportation of log() from
PGcomplexmacros.pl since
this (and sqrt() ) cause conflicts with CORE::log() and CORE::sqrt().
-- Warnings of the form "Ambiguous call to   ..... resolved in favor of
CORE::... " etc.

The functions can always be accessed by Complex::log() and Complex::sqrt()
when needed for complex numbers.

There may be a more sophisticated method of exporting these calls which
would avoid the warnings and remain transparent both to those who are
using complex numbers and those who are not.  If anyone has any ideas they
will be welcome.  The code to modify is at the top of the
PGcomplexmacros.pl file inside the _PGcomplexmacros_init subroutine.

clearer error message about what is wrong.  The check is still not foolproof.

explicitly delete CAPA options 'sig', 'tries', 'wgt' which are
meaningless to WeBWorK

Revision 194 - Directory Listing
Modified Sat Sep 8 04:51:25 2001 UTC (12 years, 7 months ago) by gage
Fixed a bug in CAPA_ans which called the old style numerical compare
and string compare functions (including some useless parameters)

This will fix several errors that have arisen in CAPA problems, but
perhaps not all of them.

two changes. First the script no longer attempts to send mail to practice users
Secondly if it encounters a bad email address, it does not just quit as before
(without sending remaining messages) rather it goes on sending all messages
and at the end lists all students for whom no message was sent.

Revision 189 - Directory Listing
Modified Tue Sep 4 22:23:09 2001 UTC (12 years, 7 months ago) by gage
Added a change to loadMacros that allows for macro files that
end in .pg

Revision 188 - Directory Listing
Modified Tue Sep 4 16:40:58 2001 UTC (12 years, 7 months ago) by gage
Modifications in these two files make questions whose answer blanks hve
the same names behave properly.

The new versions of CGI seem to return such answers as a reference to an array.
Earlier versions returned the answrs as a string with \0 separators.

With the new changes the AnswerEvaluator get_student_answer subroutine and
the NAMED_ANS_RULE in PGbasicmacros.pl will handle either a null separated
string or an answer array when dealing with vector answers.

This should correct some difficulties experienced in the linear algebra
questions.  More testing needs to be done.

Revision 183 - Directory Listing
Modified Fri Aug 31 17:16:24 2001 UTC (12 years, 7 months ago) by sh002i
Cleaned these scripts up a little. Instead of setting the PATH, it just
uses the directory specified to call each utility with its full path. Also
added some documentation and got rid of some cruft (which, of course, one
can still pull out of CVS if needed). Incidentally, all the utilities used
in these two scripts are from the netpbm package.

Modified Fri Aug 31 16:43:08 2001 UTC (12 years, 7 months ago) by sh002i
Changed pdf generation process in welcomeAction.pl to use ghostscript
directly rather than calling ps2pdf. Removed $Global::externalPs2pdfPath
and added $Global::externalGsPath.

Revision 179 - Directory Listing
Modified Fri Aug 31 16:07:39 2001 UTC (12 years, 7 months ago) by sh002i
added $externalLaTeX2HTMLSupportPath to section about LaTeX2HTML stuff...
this variable is used by displayMacros.pl:makeL2H to set the path.

Revision 178 - Directory Listing
Modified Fri Aug 31 16:06:54 2001 UTC (12 years, 7 months ago) by sh002i
makeL2H now appends the contents of $Global::externalLaTeX2HTMLSupportPath
to $ENV{PATH} before calling latex2html. this is kinda hackish, but it
works. perhaps instead of this, we should set the path globally to
something like '/bin:/usr/bin:/usr/local/bin'. (see the email i'm about
to send.)

Revision 177 - Directory Listing
Modified Fri Aug 31 15:08:51 2001 UTC (12 years, 7 months ago) by sh002i

Protect against possibility that {debug} is not defined

Revision 172 - Directory Listing
Modified Thu Aug 30 03:03:19 2001 UTC (12 years, 7 months ago) by gage
Made sure that num_cmp, fun_cmp and str_cmp return an
answer evaluator when used in scalar context.  In other words

$ans_eval = num_cmp(234);

will now work as expected -- you will get one answer evaluator which
checks whether the answer is 234.

Previously you had to write:

($ans_eval) = num_cmp(234);

or else you would have the numeral 1 placed in $ans_eval since
that is how many answer evaluators were created.

Added a default value for tolerance to is_zero_array
macro and removed the allow_unknown_defaults value.

Changed the call to is_zero_array from tol to tolerance in
FUNCTION_CMP.

Previously, because of the mislabeling of 'tolerance' as 'tol'  the
tolerance value could not be set and was always being
set to a default value.

Revererted to profSendmail from system with bug fixes (see below).
The previous version incorporated Bill Wheelers initial checking of the
validity of email addresses.  However Bill has improved (or at least
changed) this a lot.  He has sent us a new version, but we do not have
time to check it out.  We will add the functionality later

Bug fixes, etc.  SMTP is now called with the address $smtpSender.  Default

Modified lines 505-10 so that when a problem is viewed for the first time,
process_answers from PGtranslator.pm is still run with empty imput.  This
means that the correct mesages from problem graders will be displayed (and
erroneous error messages will not be displayed) the first time a problem

Added pod comments to PGanswermacros for some of the filters.

I also rearranged the structure of the file slightly to make it
easier to add the pod documentation.

Revision 118 - Directory Listing
Modified Sat Aug 11 01:46:39 2001 UTC (12 years, 8 months ago) by gage
Added code to handle warning messages for the paperHeader.pg file
as well as the problems.

Made sure that the warning messages are protected for TeX ONLY when
the output will be hard copy (i.e. when the list @PG_COMPILE_ERRORS
is empty.) otherwise the warning messages are left as HTML

Revision 117 - Directory Listing
Modified Sat Aug 11 00:25:14 2001 UTC (12 years, 8 months ago) by gage
Added logPrint to error messages when the TeX code cannot be
converted into a .dvi file.  This allows useful feedback when
there is a pure tex error -- i.e. the .pg file compiles correctly
but the resulting TeX is not well formed.

Also added some code that adds warning messages after each problem (except
the screen/pageheader file) with some extra formatting so that messages
can be handled by the TeX processor.

If this latter code is adequate it should probably be abstracted and moved
to Global near where the PG warnings handler is defined. Currently the
code modifies the Global::WARNINGS variable VERY far away from the
definition of that variable.  It would be better to have a couple of
subroutines in Global that "print" the WARNINGS string, perhaps protecting
the characters that upset TeX, and another subroutine which clears the
WARNINGS variable.

Meantime keep testing the error output -- it's looking better.

Changed package name  for error handlers to Global:: (from main::) to match
the change which occured in Global.pm version 1.6 where the handlers were moved
inside the Global.pm package.
	 $SIG{'FPE'}  = \&Global::PG_floating_point_exception_handler;
	 $SIG{__WARN__}=\&Global::PG_warnings_handler;

Warning messages from within problems and from within macros should now work again.

Revision 100 - Directory Listing

replaced \&main::PG_floating_point_exception_handler by
&Global::PG_floating_point_exception_handler

since the exception handler was moved under the package Global section of Global.pm

It's possible that  the floating point exception handler available for bad  answers
hasn't been working
properly for awhile.

Revision 71 - Directory Listing
Modified Mon Jun 25 19:22:49 2001 UTC (12 years, 9 months ago) by gage
Changed references to MatrixReal to MatrixReal1

This might break problems involving matrices or ones involving
answering questions with arbitrary constants (e.g. indefinite integral)

I believe I have caught all of the instances in which this name is used.

Revision 70 - Directory Listing
Modified Mon Jun 25 18:20:05 2001 UTC (12 years, 9 months ago) by sam

Replaced $piece1 with $piece3 in line 336 and following to avoid a
"my" conflict.  I also commented out oldivy which contained a print

Fixed errors in sourceAlias

Modified parts of alias so that PG_restricted_eval was not used.
(This is unnecessary as long as we use forking to create a child
with the same namespace.)

Revision 49 - Directory Listing
Modified Thu Jun 21 19:53:59 2001 UTC (12 years, 10 months ago) by chris

Revision 48 - Directory Listing
Modified Thu Jun 21 19:45:24 2001 UTC (12 years, 10 months ago) by sam
Added system_webwork_setup functionality to ask for the group under which
the webserver runs and chgrp the logs/ directory to that group. Thus,
logfiles have been taken out of cvs, and only the directory remains. You
can add the line
	$serverGroupName = "webwork";
to your system_webwork_setup.defaults file if you like.

Revision 47 - Directory Listing

Revision 40 - Directory Listing
Modified Thu Jun 21 13:33:27 2001 UTC (12 years, 10 months ago) by gage
Changed NUM_CMP so that the calculated versions of the student's answer
and the professor's remain in the answer hash to be displayed by
displayMacros.

There are now slight clues, when using num_str_cmp that the
instructor's answer is a string. I'm not sure anyone can find them
easily.  Further refinements should be able to remove them in any case.

Revision 39 - Directory Listing
Modified Thu Jun 21 10:21:28 2001 UTC (12 years, 10 months ago) by maria
added inv_romberg function which, given a function, a, and value computes b s.t. integral from a to b is equal

and minor bugs in solutions.

Revision 36 - Directory Listing
Modified Wed Jun 20 20:01:26 2001 UTC (12 years, 10 months ago) by gage
Simplified some of the scripts.  Using forking there is no need
to evaluate $main:: everytime, since it remains the same for both
the parent (where the script is compiled) and in the child where
the script is executed.

There were other minor fixes to work around bugs in 5.6.0 which were
fixed in 5.6.1

Revision 35 - Directory Listing
Modified Wed Jun 20 19:04:08 2001 UTC (12 years, 10 months ago) by chris

way it is called from dangerousMacros.pl

Revision 29 - Directory Listing
Modified Tue Jun 19 21:56:35 2001 UTC (12 years, 10 months ago) by gage
Fixed an evaluation which was being done at compile time rather than at
run time.  This could cause the definition of 'main' to be incorrect.

The evaluation was in an error message, so it has probably not been noticed.

Revision 28 - Directory Listing
Modified Tue Jun 19 20:56:08 2001 UTC (12 years, 10 months ago) by gage
Fixed problem in dangerousMacros.pl defining i so that it can be used
as a complex number.

when fed an undefined url.

Revision 27 - Directory Listing
Modified Tue Jun 19 20:31:39 2001 UTC (12 years, 10 months ago) by gage
Many modifications to courseScript scripts which will insure that the
routines are re-entrant (i.e. they can be called via mod_perl and don't
need to be re-compiled for every execution run.)

Minor modifications to processProblem8.pl and to PGtranslator.pm

Revision 21 - Directory Listing
Modified Tue Jun 19 12:14:14 2001 UTC (12 years, 10 months ago) by apizer
Added code giving students the choice whether or not to "show my old
answers", i.e. to show storred sticky answers.  The default for practice users
and all users after the answer date is not to show these.  Otherwise the
default is to show them.  This required a change everywhere processProblem
is called.
