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

tolerance value could not be set and was always being
set to a default value.

Revision 153 - Directory Listing
Modified Mon Aug 20 16:05:10 2001 UTC (18 years, 3 months ago) by apizer

Revision 143 - Directory Listing
Modified Thu Aug 16 21:21:13 2001 UTC (18 years, 4 months ago) by apizer
The webworkCourse.ph file now contains information on setting the
$smtpSender, defaultFrom and defaultReply variables

Revision 142 - Directory Listing
Modified Thu Aug 16 20:08:25 2001 UTC (18 years, 4 months ago) by sh002i
added this to the repository

Revision 141 - Directory Listing
Modified Thu Aug 16 20:07:49 2001 UTC (18 years, 4 months ago) by apizer
Two changes. One is to use Global::smtpSender for smtp
The other is to fill in a default from email address for the student

Revision 140 - Directory Listing
Modified Thu Aug 16 19:17:55 2001 UTC (18 years, 4 months ago) by apizer

Revision 139 - Directory Listing
Modified Thu Aug 16 18:35:08 2001 UTC (18 years, 4 months ago) by sh002i
okay, actually commented out all the courseScripts lines this time.

Revision 138 - Directory Listing
Modified Thu Aug 16 18:32:17 2001 UTC (18 years, 4 months ago) by apizer
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
values for headers now work

Revision 137 - Directory Listing
Modified Thu Aug 16 18:29:27 2001 UTC (18 years, 4 months ago) by sh002i
commented out lines that chmod courseScripts directory (as I recall, that
directory is no longer used).

Revision 136 - Directory Listing
Modified Wed Aug 15 15:03:08 2001 UTC (18 years, 4 months ago) by sh002i
Actually changed the value of $Global::externalLaTeX2HTMLInit. Sorry about
that. :P

Revision 135 - Directory Listing
Modified Wed Aug 15 14:45:38 2001 UTC (18 years, 4 months ago) by ch003i
Added 'allow_unknown_options' in is_a_zero_array filter to avoid error in function_cmp routine.

Revision 134 - Directory Listing

Reordered some config items, changed $externalLaTeX2HTMLInit.

Revision 133 - Directory Listing
Modified Tue Aug 14 20:59:15 2001 UTC (18 years, 4 months ago) by sh002i
Renamed latex2html.init.98.1 latex2html.init.98.1p1 to make it able to be

Revision 132 - Directory Listing
Modified Tue Aug 14 20:45:45 2001 UTC (18 years, 4 months ago) by sh002i
Unreferenced file -- removed.

Revision 131 - Directory Listing
Modified Tue Aug 14 20:25:40 2001 UTC (18 years, 4 months ago) by apizer
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
is viewed.

Revision 130 - Directory Listing
Modified Mon Aug 13 20:42:26 2001 UTC (18 years, 4 months ago) by sh002i
moved latex2html init files to lib.

Revision 129 - Directory Listing
Modified Mon Aug 13 20:42:12 2001 UTC (18 years, 4 months ago) by sh002i

Modified Mon Aug 13 20:41:26 2001 UTC (18 years, 4 months ago) by sh002i
Fixed makeL2H to use $Global::externalLatex2HTML{Path,Version,Init} vars.

Revision 127 - Directory Listing
Modified Mon Aug 13 20:29:42 2001 UTC (18 years, 4 months ago) by apizer
removed all reference to courseScripts directory (which is no longer used
by individual courses).  Also the default now in setting up a course is to
have the macros directory implemented.  Added comments on the
webworkCourse.ph file explaining how the macros directory works.

Revision 126 - Directory Listing
Modified Mon Aug 13 18:26:55 2001 UTC (18 years, 4 months ago) by sh002i
Moved from blankCourse, changed index.html from 0644 to 0664.

Revision 125 - Directory Listing
Modified Mon Aug 13 18:12:32 2001 UTC (18 years, 4 months ago) by gage
Updating pod documentation

Revision 124 - Directory Listing
Modified Mon Aug 13 16:09:14 2001 UTC (18 years, 4 months ago) by gage
Updating pod documentation

Revision 123 - Directory Listing
Modified Mon Aug 13 16:07:32 2001 UTC (18 years, 4 months ago) by gage
Removed warning message about avg_problem_grader, since now
avg_problem_grader is also installed in PGtranslator and can
be used as a default grader. (std_problem_grader can also be
used as a default).

Revision 122 - Directory Listing
Modified Sat Aug 11 03:17:43 2001 UTC (18 years, 4 months ago) by gage
More adjustments to documentation for answer evaluators

Revision 121 - Directory Listing
Modified Sat Aug 11 02:26:08 2001 UTC (18 years, 4 months ago) by gage
The pod documentation is now read from the mainDirectory as
defined in Global.

Revision 120 - Directory Listing
Modified Sat Aug 11 02:25:08 2001 UTC (18 years, 4 months ago) by gage
More documentation added.

Revision 119 - Directory Listing
Modified Sat Aug 11 01:48:05 2001 UTC (18 years, 4 months ago) by gage
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 (18 years, 4 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 (18 years, 4 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.

Revision 116 - Directory Listing
Modified Fri Aug 10 19:29:56 2001 UTC (18 years, 4 months ago) by sh002i
> STRANGE BUG
fixed the strange bug!

Revision 115 - Directory Listing
Modified Fri Aug 10 19:03:37 2001 UTC (18 years, 4 months ago) by sh002i
Rewrote downloadAllSets to mak sense, fixed error reporting, fixed several
"used only once" warnings, enhanced filename handling for downloaded files
(this is very nice -- it can tell whether we're getting one set for
multiple students or multiple sets for one student :), changed temp file
naming scheme. what fun!

Revision 114 - Directory Listing
Modified Fri Aug 10 18:58:31 2001 UTC (18 years, 4 months ago) by ch003i
Edited l2h_sticky_answers to stop unwanted combining when answers used multiple fields.

Revision 113 - Directory Listing
Modified Fri Aug 10 15:38:29 2001 UTC (18 years, 4 months ago) by sh002i
No longer needed since welcomeAction.pl version 1.9

Revision 112 - Directory Listing
Modified Fri Aug 10 15:35:24 2001 UTC (18 years, 4 months ago) by sh002i
1. Fixed prepareHardcopy. Actually works now.
2. Incorporated old error reporting code into downloadAllSets
This file is incredibly hairy and should be cleaned up/split up a.s.a.p...

Revision 111 - Directory Listing
Modified Fri Aug 10 14:34:02 2001 UTC (18 years, 4 months ago) by sh002i
added variables for paths to hardcopy generation programs

Revision 110 - Directory Listing

Changes made to best approximation parameters -- added
set_default_options call.  Removed some warning messages.

Revision 109 - Directory Listing
Modified Thu Aug 9 21:37:29 2001 UTC (18 years, 4 months ago) by gage
AnswerEvaluators can now handle ans_hash as an input (this allows
the answerevaluator to be used as a filter in another answer evaluator

Cosmetic changes made to the error reporting when the debug
flag is set.

Revision 108 - Directory Listing
Modified Thu Aug 9 16:25:05 2001 UTC (18 years, 4 months ago) by ch003i
Edited check_eigenvector to include debug option and fixed post-filter to prevent crashing.

Revision 107 - Directory Listing
Modified Wed Aug 8 23:43:43 2001 UTC (18 years, 4 months ago) by gage
Made small corrections at lines 417 and 484 which were
causing compile time errors in /ww/logs/error_log.  (One
was redefining rh_flags subroutine, the other was an
uncommented fragment of a print statement.

Revision 106 - Directory Listing
Modified Wed Aug 8 16:26:11 2001 UTC (18 years, 4 months ago) by sh002i
This was an unreferenced copy of latex2html.init.96.1

Revision 105 - Directory Listing
Modified Wed Aug 8 16:17:10 2001 UTC (18 years, 4 months ago) by gage
Modified warning so that warnings when end in \n (or in ~~n for .pg files) do not have the extra
stack information appended.  This may sometimes make for cleaner output messages.

Revision 104 - Directory Listing
Modified Wed Aug 8 15:29:51 2001 UTC (18 years, 4 months ago) by gage
Made sure that the error handlers have Global:: prefixes

Revision 103 - Directory Listing
Modified Wed Aug 8 02:29:05 2001 UTC (18 years, 4 months ago) by gage
Changed names in calculate difference vector   subroutine to make the
process a bit clearer.  There is still more work to be done.

Revision 102 - Directory Listing
Modified Wed Aug 8 02:24:16 2001 UTC (18 years, 4 months ago) by gage
Minor  changes to the #!/usr/bin/perl line

Revision 101 - Directory Listing
Modified Wed Aug 8 02:17:35 2001 UTC (18 years, 4 months ago) by gage
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
Modified Wed Aug 8 02:13:25 2001 UTC (18 years, 4 months ago) by gage
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
when the BEGIN block was moved in version 1.6

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

Revision 99 - Directory Listing

need to me mangled!

Revision 93 - Directory Listing
Modified Tue Aug 7 16:11:09 2001 UTC (18 years, 4 months ago) by sam
Added index.html file as a placeholder for removed docs. This allows
browser requests for the directory to yield a useful error message rather
than "FORBIDDEN"

Revision 92 - Directory Listing
Modified Tue Aug 7 16:05:31 2001 UTC (18 years, 4 months ago) by sam
1. Set all "WeBWorK docs" links to http://webwork.math.rochester.edu

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.

Modified Thu Jun 21 19:53:59 2001 UTC (18 years, 5 months ago) by chris
Added "evaluatesToNumber" subroutine.  In conjunction with fix_answer_for_display filter, this now fixes a bug with displaying student_ans in a problem that allows strings for valid answers.

Revision 48 - Directory Listing
Modified Thu Jun 21 19:45:24 2001 UTC (18 years, 5 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 (18 years, 5 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 (18 years, 5 months ago) by maria

and minor bugs in solutions.

Revision 36 - Directory Listing
Modified Wed Jun 20 20:01:26 2001 UTC (18 years, 5 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 (18 years, 5 months ago) by chris

way it is called from dangerousMacros.pl

Revision 29 - Directory Listing
Modified Tue Jun 19 21:56:35 2001 UTC (18 years, 6 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 (18 years, 6 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 (18 years, 6 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 (18 years, 6 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.
