Sticky Revision:
Revision 3311 - Directory Listing
Modified Thu Jun 23 02:33:03 2005 UTC (7 years, 11 months ago) by gage 
The TIMEOUT constant which is now defined in WeBWorK::Cosntants  and is
(and was) used in WeBWorK::PG::Local  gives the time in seconds
that is allowed for rendering one PG problem.  The old value was 5 minutes
which was probably way too long. The default in WeBWorK::Constants has been
set to 60 seconds.  If no value is set then 10 seconds is used.

Revision 3224 - Directory Listing
Modified Sat May 14 01:32:19 2005 UTC (8 years, 1 month ago) by dpvc 
Changes needed to make loadMacros() look through a path of directories
rather than just course/templates/macros and pg/macros.  You can
specify the path in the global.conf file.

You also need to make the update to pg/macros/dangerousMacros.pl
Revision 3073 - Directory Listing
Modified Sat Jan 1 22:35:10 2005 UTC (8 years, 5 months ago) by gage 
Changes made to simplify the implementation of XMLRPC access to
the functionality of WeBWorK.

There is still a problem with making sure that the proper warning
mechanism is passed into the problem rendering compartment.
The proper permissions for creating directories also does not
get transmitted properly.

I would like to change the way that the defineEnvirVars subroutine is
passed into the Local.pm object.  I'd like to either pass the
environment as a hash or explicitly pass a reference to define
EnvirVars rather than inherit it from PG.  In particular I'd like
to be able to define environment variables directly in RenderProblem.pm
instead of faking it by defining fake problem objects.
Revision 2929 - Directory Listing
Modified Fri Oct 15 20:33:04 2004 UTC (8 years, 8 months ago) by gage 
Removed writing to Timing log from this module.
Revision 2778 - Directory Listing

timezone support
Revision 2418 - Directory Listing
Modified Sat Jun 26 20:44:54 2004 UTC (8 years, 11 months ago) by jj 
Minor additions so that ImageGenerator can get image alignment right.
Revision 2268 - Directory Listing
Modified Mon Jun 7 02:13:27 2004 UTC (9 years ago) by sh002i 
Added timeout alarm (currently set to 5 munites). Fixes bug #511.
Revision 1703 - Directory Listing
Modified Mon Jan 5 01:02:41 2004 UTC (9 years, 5 months ago) by sh002i 
removed lingering references to "webwork-modperl", since we're calling
this product "webwork2" now. soon we should change the name of the CVS
module to "webwork2" as well.
Revision 1663 - Directory Listing
Modified Tue Dec 9 01:12:32 2003 UTC (9 years, 6 months ago) by sh002i 
Normalized headers. All files now contain the text below as a header.
This is important since all files now (a) use the full name of the
package, (b) assign copyright to "The WeBWorK Project", (c) give the
full path of the file (relative to CVSROOT) instead of simply the file
name, and (d) include license and warranty information.

Here is the new header:

Revision 1558 - Directory Listing
Modified Wed Oct 1 02:57:55 2003 UTC (9 years, 8 months ago) by sh002i 
1. moved common functions from PG::Local and PG::Remote to PG and made
them methods so that inheritence would work.
2. made some changes to PG::Remote to make it work with renderd
Revision 1554 - Directory Listing
Modified Tue Sep 30 01:32:53 2003 UTC (9 years, 8 months ago) by sh002i 
moved to pg
Revision 1538 - Directory Listing
Modified Sat Sep 27 16:34:45 2003 UTC (9 years, 8 months ago) by gage 
Modified process_answers so that each student answer is modified in this way:
(1) if the answer is undefined, then it is replaced by an empty answer
(2) if the answer contains null spaces then the answer string is split along the nulls (\0)
and the answer variable is replaced by a reference to this array.

A few clauses in filter_answers and in AnswerEvaluator::get_student_answer are now redundant
but I've left them in for now.  The filter_answer subroutine was replacing all nulls by
blanks, which caused the difficulty with handling vectors.

Revision 1262 - Directory Listing
Modified Tue Jun 24 14:51:42 2003 UTC (9 years, 11 months ago) by gage 
Changes made to insure that WeBWorK2.0 will run when it is
not optimized for time.  I'm planning to commit a "stable" version,
not feature complete, from which optimization branches can be derived.
--Mike
Revision 1249 - Directory Listing
Modified Mon Jun 23 14:24:13 2003 UTC (9 years, 11 months ago) by gage 
Added caching code for reading PGbascimacros and PGanswermacros as well
as PG.pl, dangerousMacros and IO.pl into a cached safe compartment and
sharing the subroutines with the current safe compartment
It speeds up each problem significantly (about .2 seconds on webwork3).

Changes are required in PGbasicmacros and PGanswermacros to fix
assumptions that are not met when a file is compiled and run in
different name spaces.

The caching code is turned off by default.  It must be turned on by
by changing commenting in lines 133 to 147 in WeBWorK::PG:Local.pm

Revision 1163 - Directory Listing
Modified Fri Jun 13 18:07:54 2003 UTC (10 years ago) by sh002i

-sam
Revision 1159 - Directory Listing
Modified Fri Jun 13 17:26:40 2003 UTC (10 years ago) by sh002i 
removed unneeded code from WeBWorK::PG, WeBWorK::PG::ImageGenerator::add
now supports both add($in_delim) and add($in, $mode).
-sam
Revision 1154 - Directory Listing
Modified Fri Jun 13 02:30:45 2003 UTC (10 years ago) by sh002i 
Rewrote ImageGenerator to work with WeBWorK2. Its arguments are now
passed in via an options hash instead of getting a whole %envir. Also,
the options are passed to the constructor and there is no initialize()
method. add() has the same interface, and render() has been changed
slightly. (This closes Bug #80!)

To make this work with 1.8, take a look at how I'm creating
ImageGenerator in &WeBWorK::PG::defineProblemEnvironment and make the
necessary modifications to processProblem8.pl.

I made changes to WeBWorK::PG to have "images" mode trigger HTML_dpng
rather than HTML_img, and also to create an ImageGenerator before
initializing and call render() after translation.

Also in PG, I shortened the names of the equation image files. They're
now "equation-$PSVN-$probnum-$seed.png". This has the added benefit of
forcing image regeneration if the problem seed changes, closing Bug
#70.

Equation files are now dumped directly into the $courseDirs{HTML_temp}
directory. This means that no one has to worry about whether "m2i"
exists any more.

global.conf.dist was changed to not include the switches to dvipng on
the command line (they're currently hardcoded into ImageGenerator).

I still have to get this to work with dvipng 0.3. I should also take
advantages of 0.3's new features, like pipelining (using the -follow
switch) and specifying the output file name (to avoid the "move" of
resulting images).

This is MUCH FASTER than the way I was calling dvipng, and I think it's
safe to say that it's a better method. Thanks JJ!

- added warning reporting to conf/templates/ur.template (but not to
  other templates!)
- modified a couple of error messages in WeBWorK.pm
- made failure to create course environment and failure to find course
  directory fatal errors in WeBWorK.pm
- added warning queueing and call stack storing to Apache::WeBWorK
- added "warnings" and "if_warnings" template escapes to
  WeBWorK::ContentGenerator
- removed warning handling from WeBWorK::ContentGenerator::Problem
- code tidying in WeBWorK::ContentGenerator::Problem
- code tidying in WeBWorK::PG::ImageGenerator

Revision 1116 - Directory Listing
Modified Wed Jun 11 03:59:00 2003 UTC (10 years ago) by gage 
Added a feature to process_answers.  Each answer evaluator is given the
answer AND the answer label (e.g. AnSWer1) of the answer.  The label
is placed in the answer hash at $hash{ans_label} for use by filters
that need to know the label of the answer they are evaluating.

A corresponding change has been made in AnswerEvaluator in AnswerHash.pm

-sam
Revision 637 - Directory Listing

-sam
Revision 624 - Directory Listing
Modified Sat Nov 9 15:50:38 2002 UTC (10 years, 7 months ago) by gage 
Changed warning messages when dvipng doesn't work from die to warn.
This gives more infformation back to the webbrowser and still prints the
same information to the log.

Removed the workaround for dvipng's problems with labeling its dvi
output.  This problem was fixed in the latest version of dvipng which is
now being used on webwork-db and webwork.

There is still a problem that dvipng is being used to display answers at
all times (even if the mode switch is set to tth mode )

were used where apprropriate.
-sam
Revision 562 - Directory Listing
Modified Fri Sep 27 23:53:42 2002 UTC (10 years, 8 months ago) by sh002i 
- created macros/IO.pl, which is loaded with no opmask by PG.pm. It is a copy
  of WeBWorK::PG::IO.pm, with some changes to make it work as a macro package.
  The translator no longer shares IO.pm's functions with the safe compartment.
  This is a BAD THING, and should be reconsidered when the Translator is
  revised.
- Changed many (but not all) checks for HTML or HTML_tth modes to match /^HTML/
  in the macros.
- changed &header to &head in Problem.pm
- Added problem environment variables for gif2eps and png2eps and modified
  &dangerousMacros::alias to use them
- fixed MOST of the harmless warnings in the system. there's still the "Use
  of uninitialized value in null operation" warning in template(), tho.

Still to come:

- make images in PDFs work
- fix TTH mode character encodings on mac (maybe)
- have logout button invalidate key
- Pretty die messages (from outside of the translator)
- Feedback - need nice modular way of sending email
- Options - email address and password
