Possible to show runtime errors to competitors?
by Matthew Fahrenbacher 18 Dec '15

18 Dec '15

Hi all - is there a way to make runtime errors visible to competitors? I'd like our competitors to see that they are getting exceptions (ArrayIndexOutOfBoundsException, etc) and at what line of code (for java). Is this something that can be enabled? Thanks, Matt Fahrenbacher Niles West High School Skokie, Illinois

Dear admin, I am a student at University of Information Technology, I'm going to use Domjudge to organize our contest (ACM), I followed your Admin Manual Installation Guide, but I always get error when install Domjudge: -- Before, I get error about jsoncpp-devel. Then, I add --disable-submitclient in configure line. This was not happened. -- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format. -- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page. I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.

Creating team and user accounts in batch mode
by Howard Cheng 16 Nov '15

16 Nov '15

Hi, I would like to create teams and user accounts in batch (e.g. from a spreadsheet). I'm using DOMjudge 4.0.5 and I see that there is an "Import / export" option, but I can't find much documentation on this. I have also somewhat successfully crafted my own SQL statements to insert tuples into the tables directly, but the problem is that I have to ask for the current id for the auto_increment fields of various tables and match them up. It's not a big deal, but if there is an easier option then I would like to know about it. Thanks.

Judgehost Shared Directories?
by Marc Furon 13 Nov '15

13 Nov '15

I will be running several judgehosts in an environment where the OS image is coming from a flash drive. NFS is also available to the contest server. It looks like several of the judgehost directories (judgings, log, run, and tmp) create sub-directories by hostname and could therefore be shared over NFS. Is there any documentation that describes the best practices for doing that? I read through the administration manual but didn't see anything specifically addressing that topic. Marc

Sample Data for Contestants?
by Marc Furon 12 Nov '15

12 Nov '15

Greetings! Perhaps I'm mistaken...but isn't there a way for contestants to download the input and output files marked "sample" for a given file from inside DOMjudge? I thought this was possible but I don't see how, and I looked through the documentation. One other question, if someone knows: is the information about the contest start time and end time available inside the renderScoreBoardTable function? I figured out how to do everything else I want with the scoreboard but there is one thing I want to do once the contest is half over. It looks like the information might be in the $cdata variable--is there a description of the internal data structures somewhere? Our contest is Saturday and it looks like things are coming together...this is the first year I have been delving deep into DOMjudge, and I am impressed with what I have found. Thanks to the team for developing and maintaining the system. Marc

Could you please look on the domjudge-live image under /var/lib/domjudge/judgings/domjudge-live-0/endpoint-default There should be subdirectories of the form cX-sYY-jZZ for each submission/judging there. Check in the webinterface what one of the java compiler-errror's submission and judging ID is and please send a zip file of that directory. The files compile.{out,tmp,meta} may contain some clues as to what goes wrong.

Scoreboard Timing?
by Marc Furon 02 Nov '15

02 Nov '15

Hello! We are working on re-implementing a couple of changes we made to a earlier version on DOMjudge in Southern California. One of the changes is to time to the second instead of the minute. It looks to me like the scorecache_ tables are what is used to build the scoreboard displays for the public and the jury. I see the time is currently stored in those tables in minutes, but it also looks like there is one function (calcScoreRow) that populates the table, and it is doing the division by 60 to get minutes. If the scorecache_ tables are not used for anything else, I see no reason why I couldn't change that function in order to get seconds. Is my understanding correct? Marc
