30 Jun '22

Hello, I'm currently new in this field and want to ask a few questions regarding creating a problem on domjudge. First of all, I have one problem and I want to add it to the domserver. I have the pdf (text) for the question and .cpp for the solution. What do i have to configure to add the problem to the server, what is the meaning of run and compare script, and how do I insert the .cpp solutions file to the problem? Thank you!

Hi Sunny, We can not really help you further than what is in the documentation. If you, or someone you know, has experience with Docker, it might be easier to use that to set up DOMjudge.

I am currently on holiday so I can not answer extensively, but basically the demo is our master branch, which is indeed newer. We plan to release it in September or October. I have forwarded your mail to the DOMjudge development list (see cc). Perhaps one of the others can answer in more detail.

DOMJudge with Kotlin
by Alan 10 Mar '19

10 Mar '19

I am trying to get Kotlin to work with DOMJudge, but I am having issues. I installed Kotlin in both the host OS and CHROOT. I am able to run kotlin commands in the Host OS and in CHROOT, I'm also able to run kotlin commands using the full path to where I unzipped it in the execution script. I am submitting the test hello world to the example Hello World challenge. I am getting the following error: Compiling failed with exitcode 1, compiler output: Info: using main class provided by ENTRY_POINT='Test_helloKt'. error: invalid argument: -d info: use -help for more information I believe this is referencing kotlinc -d as that's the only place I can see -d in the execution script. But, I am fully able to run kotlinc -d in the terminal. Version: DOMJuge 6.0.3 OS: Ubuntu 18.04 on AWS Apache2 -- Alan S.

DomJudge Compilation Error
by Marshal Dong 22 Feb '19

22 Feb '19

Hello Everyone, So I ran into some trouble when testing DomJudge. I created a user to submit the hello world solution in the demo contest, and I tried several different languages. However, I cannot pass the judgehost... Below is the compilation output. Any help would be greatly appreciated!

Setting judgehost password programatically, via MariaDB cli client
by Michał Kaczanowicz 20 Feb '19

20 Feb '19

Hello everybody! My current task is to deploy domjudge - or more precisely, to create a "one click deploy" configuration. I aim to use docker images of domserver and domjudge. I'd like to accomplish my task using docker and docker compose. But here comes a slight problem. After setting up domserver, I need to set new password for judgehost user. Setup manual suggest to do it "by hand", via web interface on admin account. Is there a way to do that programatically, e.g. simply updating password for judgehost user in domjudge.user table? How is the hash computed? Best regards, Michał Kaczanowicz

Live CD
by Matthew Fahrenbacher 27 Jan '19

27 Jan '19

Hi all. So I'm almost done with my next contest, but I see that the Live Images haven't been updated in about a year, so the version of the judgehost on the Live Image won't match with the latest release of the domjudge server. (I tried the most recent Live Image, and it didn't want to boot, even though older ones would). I'm about to go through the process of building one myself following the directions here <https://github.com/DOMjudge/domjudge-packaging/blob/master/live-image/files…>, but I wanted to check first to see if a prebuilt one was going to be created in the near future to save me the hassle. Thanks! Matt Fahrenbacher Niles West High School

Strange Network Issue
by Matthew Fahrenbacher 16 Jan '19

16 Jan '19

I'm not sure if anyone can explain this issue. I'm about to setup a server to run a domjudge programming competition (I've done this successfully a few times before). I installed a fresh linux install yesterday and loaded up the domjudge website to read through the directions (everything was fine). Today, for no reason that I can comprehend, I am now unable to load the domjudge website on my school's network. I checked on my cellular network, and everything is fine. I checked with my IT staff, and they say they are not blocking traffic to the domjudge website. For some reason, all our traffic that we send there is not being replied to. Does anyone have a theory for why this is happening? Thanks, Matt Fahrenbacher Niles West High School

Demoweb breakages
by Robin Lee 24 Dec '18

24 Dec '18

Hello, First, thanks for the updates to domjudge.org/demoweb. It's nice to have a recent version of DOMjudge up on there to test against! Two URLs don't seem to work after this: * https://www.domjudge.org/demoweb/api/contests/5/scoreboard (500 Internal Error) * https://www.domjudge.org/demoweb/public/ ("lib/relations.php missing") The first one is quite important to me because I want to test against it with a resolver thingy I've been working on; the second one is probably quite important to new users poking around. Are the team already aware these are broken? Thanks, Robin

Automatic testing of jury solutions
by Maarten Sijm 29 Nov '18

29 Nov '18

Hi, I am planning to set up automatic testing of jury solutions using continuous integration. >From the admin manual (section 4.7), I've found that testing jury solutions can be done by uploading the problems to the system, but I would like to circumvent this manual task. I already have a naive shell script set up that does some basic diffing, which works for simple problems. However, I thought there might be already some tool that automatically verifies solutions. I've found that Kattis has a tool to verify problems: https://github.com/Kattis/problemtools However, I can imagine that this `verifyproblem` tool uses different settings than what would be used on a DomJudge instance. Could I get some advice on how I could best set this up? Kind regards, M.P. Sijm

Strange Behavior
by Marc Furon 10 Nov '18

10 Nov '18

I am getting ready for our contest tomorrow. Thanks to Keith, I have Apache and php-fpm configured. I tried installing the domjudge.conf file for php-fpm but it looks like my system is using the default www.conf configuration. However, as I test submitting here at the site, it's not working. I log in as a user, get the initial screen (as part of the "demo" contest), click Submit, select my source code, problem, and language. I'm asked to confirm if I really want to submit. I then go right back to the same screen. There is no entry on the screen for the submission. Nothing happens on the judgehost (which did register, and is waiting for work). Where can I check to see what is going on? I'm also trying to set up IRC but I've not used it before. Marc

Am I looking in the right place to > ensure that we don't run out of web service resources again? 100 teams should be pretty easy to support on hardware with those specifications. For PHP-FPM, there are a couple of relevant parameters to tune based on your system. The first is pm = static. This disables scaling of fpm workers so there are always a fixed number of workers available. To control how many fixed workers, that's the pm.max_children variable. It looks like the domjudge-fpm.conf file that ships with domjudge seems to set these, and gives some guidance for how to set it, but I think the comment might be a little bit out of date since the move to symfony which requires a bit more memory. Running domjudge on master a few weeks back, I seem to recall 100-150mb per fpm worker on average. So the value you choose for max_children should be based on this. E.g. if you want to use 10gb of your server memory then you'd want to set it to around 70(which is probably plenty for 100 teams). You should also make sure that pm.max_requests is set to some reasonably large non-zero value. This just protects you from unknown memory leaks by restarting fpm worker processes after some number of requests(I use 5000). I've never used apache in front of php-fpm, but you may want to check the MaxRequestWorkers/KeepAliveTimeout/KeepAlive setting. If you are on a local network/not using ssl probably you can just disable keepalive to ensure you don't run into the errors encountered last year. The best thing you can do though is to do some load testing to see what happens under load. You can probably accomplish this with just apachebench, but make sure you point it at a real page(i.e. something that isn't just a 302 redirect or a static file or something like that). A good page is probably the login page; do a curl -I on it first to make sure it returns a 200 OK + some actual content. For 100 teams you're probably only looking at like 10 requests/second tops(team pages refresh every 30 seconds, which is like 3 reqs/sec. Add in some spectators and people who open multiple tabs and that gets you to 10ish). That said your server should be able to do way more requests/sec than that. An apachebench command that would simulate using keepalive + 150 concurrent users would be something like this: ab -k -c 150 -n 15000 example.com/domjudge/login In the results you'll want to pay attention to a few things: The 99th/all percentiles at the bottom, and the max time for each. You'd want to see something like 95% of requests less than a couple hundred ms, and 100% of requests under 1-2 seconds or so. I think there is also a count for errors(if it happens to blow up), but you want that to be zero. Play with the values for the -c argument to test more/less concurrent "users" so you can get a good idea for what your server can handle(I would keep increasing this until you discover at what point it starts to fail). You might also want to watch memory usage of the php-fpm workers and tune the pm.max_children values as needed. An aside, I don’t run apache(opting for nginx instead), but I try to configure it to set caching headers for css/png/jpg/etc, as this will reduce the load on the server. Make sure you’re all set with customizations as it’ll be difficult to css/js after the fact. You can skip this step if you’d like, 100 teams is not that many and a properly configured server should be able to easily serve that many requests. The judge hosts check in periodically, so make sure you account for them in your load testing. More judge hosts = more requests making it to the domjudge server. Sometimes substantially so, e.g. in the case of a problem with ~100 test cases and a tiny runtime you’ll probably see multiple requests per second just to judge that. So if you have lots of judge hosts that can negatively impact the performance of your web server. I hope that rambling is helpful in some way and provides you some useful tuning options. -Keith

ICPC Import Error

Apache/DOMjudge Tuning
by Marc Furon 08 Nov '18

08 Nov '18

In the interest of avoiding the issue we had last year we want to ensure we have plenty of web service resources available for DOMjudge this weekend. I have installed DOMjudge 6.0.2 and it seems to be working. When I look at the current processes running (with the default configuration) I see five httpd processes and five php-fpm processes. From what I can tell, it looks like I should use php-fpm tuning parameters to greatly increase the number of php-fpm processes running. (We have 16 GB of RAM, so I see no problem with doing so.) Does the DOMjudge team have any recommendations on which parameters to change to support 100 teams? Am I looking in the right place to ensure that we don't run out of web service resources again?

Login Screen?
by Marc Furon 05 Nov '18

05 Nov '18

I am setting up 6.0.2 in preparation for Southern California's contest next weekend. We run on Fedora, in this case Fedora 28. I installed DOMjudge to /opt/domjudge, configured MariaDB, and copied the Apache configuration file to /etc/httpd/conf.d. I can connect to localhost/domjudge and I see the default scoreboard. However, when I click "Login", I get a blank screen! As far as I can tell everything is there. Does anyone have any ideas about what might be going on? Marc

judgehost API changes to do performance improvements
by Tobias Werth 01 Nov '18

01 Nov '18

Hi, Since I have noticed that we are doing very poorly for problems with many test cases, I have looked into what causes how much of the slowdown (compared to verifyproblem it's 50x for the insane WF problem). The least invasive improvement we can do is in making some changes to the judgehost API. I would like to do those changes before we make the next release aka before NWERC so that we don't (have to) change the API in the next release again. Currently the API requests for one judging look like: API request POST judgehosts/next-judging/bar-0 *Judging submission s92 (endpoint default) (t1/p9/cpp), id j257...* API request GET config data=name=script_timelimit API request GET config data=name=script_memory_limit API request GET config data=name=script_filesize_limit API request GET config data=name=process_limit API request GET config data=name=output_storage_limit *^-- above requests could be grouped together already today, but that doesn't bring a big win (I'll do it anyway)* Working directory: /home/sitowert/domjudge/output/judgings/bar-0/endpoint-default/c2-s92-j257 API request GET contests/2/submissions/92/source-code API request PUT judgehosts/update-judging/bar-0/257 data=compile_success=1&output_compile=a25pZ2h0REsuY2M6IEluIGZ1bmN0aW9uICdpbnQgbWFpbigpJzoKa25pZ2h0REsuY2M... executing chroot script: 'chroot-startstop.sh start' API request GET config data=name=timelimit_overshoot *^--- could also be grouped to the config requests above* API request GET testcases/next-to-judge/257 Running testcase 1... API request POST judgehosts/add-judging-run/bar-0/257 data=testcaseid=94&runresult=correct&runtime=0.001&output_run=MTIK&output_error=&output_system=Q29ycmVjdC... Testcase 1 done, result: correct API request GET testcases/next-to-judge/257 Running testcase 2... API request POST judgehosts/add-judging-run/bar-0/257 data=testcaseid=95&runresult=correct&runtime=0.001&output_run=Ngo%3D&output_error=&output_system=Q29ycmVj... Testcase 2 done, result: correct API request GET testcases/next-to-judge/257 Running testcase 3... API request GET testcases/95/file/input API request GET testcases/95/file/output *^--- this is only done for unknown/changed testdata* *-----------------------------------------------------------------------------------------------------------* In the future, I want to have it rather like this flow: API request POST judgehosts/next-judging/bar-0 *^--- this will additionally return all the md5sums for all inputs/outputs of the problem* *Judging submission s92 (endpoint default) (t1/p9/cpp), id j257...* API request GET config data=name=script_timelimit,script_memory_limit,script_filesize_limit...timelimit_overshoot Working directory: /home/sitowert/domjudge/output/judgings/bar-0/endpoint-default/c2-s92-j257 API request GET contests/2/submissions/92/source-code API request PUT judgehosts/update-judging/bar-0/257 data=compile_success=1&output_compile=a25pZ2h0REsuY2M6IEluIGZ1bmN0aW9uICdpbnQgbWFpbigpJzoKa25pZ2h0REsuY2M... executing chroot script: 'chroot-startstop.sh start' API request GET testcases/95/file/input API request GET testcases/95/file/output *^--- request all unknown/changed testdata* Running testcase 1... Testcase 1 done, result: correct Running testcase 2... Testcase 2 done, result: correct Running testcase 3... Testcase 3 done, result: wrong-answer API request POST judgehosts/add-judging-run/bar-0/257 data=TBD *^--- this is actually the result of three testcases* API request GET testcases/next-to-judge/257 *^--- this is the check whether we should continue judging* *-----------------------------------------------------------------------------------------------------------* The main idea is to not do the next-to-judge calls (as long as possible) and to group the add-judging-run calls. The next-to-judge calls are not necessary as long as all previous test cases are correct. For the most commonly used judging model (fail on first error) this is true for at least N-1 of N test cases. Now we still want to ping back from time to time to a) signal progress, and b) not to post too much data back in the database at once. So I could imagine reasonable default values is to post back at least every 10s and if we accumulated more than twice the output limit but that should be configurable. For the actual grouping/batching I can see two options: either allow the one POST add-judging-run call to allow multiple results to be posted or follow something like this: https://developers.facebook.com/docs/graph-api/making-multiple-requests to do batched requests across the API. For a problem with N test cases and M unknown test cases, this approach will bring us down from 9 + N*2 + M*2 API calls to 4 + M*2 + X/10 + 2 API calls (<-- in the best case of a correct problem of course with X seconds of total judging time) Any objections or thoughts? Tobi

Domjudge
by Marcel Bezdrighin 12 Oct '18

12 Oct '18

After installing the new 6.0 domjudge the same way as I did 5.3.3, I keep getting an 404 error when trying to access the main page: The requested URL /home/marcel/domjudge/domserver/webapp/web/app.php was not found on this server. 5.3.3 is working fine if I follow the same steps. The directory exists and the file “app.php” is also present. Moreover if I try to access “app.php” directly then I’m redirected to /public/ but then I get exactly the same error. It also seems the static files are working fine because I can access them easily. This seems to be a problem with setting up apache and how Symfony works, but I’m not very good at this stuff so I couldn’t solve it.

Time Factor Not Getting Accounted when calculating maxruntime
by Abhishek Kumar 30 Aug '18

30 Aug '18

Hi Team, I was running Scala on Domjudge version 5.1 but the compiler gave timelimit execption.So i increased the timefactor in language entry but still it gave timelimit exception When i further looked into it, it was always passing maxruntime as 1 in every case since the below sql query always returned null *File Path*(domserver/www/api/index.php) *Sql Query*: SELECT s.submitid, s.cid, s.teamid, s.probid, s.langid, s.rejudgingid, CEILING(time_factor*timelimit) AS maxruntime, p.memlimit, p.outputlimit, special_run AS run, special_compare AS compare, special_compare_args AS compare_args, compile_script FROM submission s LEFT JOIN problem p USING (probid) LEFT JOIN language l USING (langid) WHERE submitid = 5326 So i need to know how can i change this .Since i want my time factor get accounted when calculating maxruntime Eagerly waiting for your reply Thanks Abhishek

DOMjudge hackathon(s)
by Nicky Gerritsen 28 Jul '18

28 Jul '18

Hi all, As the programming contest season is rapidly approaching, we would like to make sure we have a stable version of DOMjudge which we can release. Our main goal for the next release (which will be 6.0) currently is to incorporate all changes we made during last season, especially during and on the way to the world finals. There is a separate icpc-live branch we desperately want to get rid of, but it still requires some work, for example to create config flags to put some features “behind”. Furthermore it would probably be nice to continue with the new looks. Because our previous hackathons resulted in a lot of completed work in a small amount of time, we would like to organise another one (or two) during the summer. If you want to join (everyone is welcome, even if you never coded on DOMjudge before), please fill in this Doodle poll: https://doodle.com/poll/rwuuasewi7k4zrwe <https://doodle.com/poll/rwuuasewi7k4zrwe> As most of the core developers are in the Europe/Amsterdam timezone, we will probably plan a whole day (somewhere between 10:00 and 20:00 CEST), but you are always welcome to join for shorter periods. Some of us might meet up in real life, but of course you are welcome to join “online”. If you have any more questions feel free to contact us! On behalf of the DOMjudge team, Best, Nicky

[Domjudge]: Run checker developed in Checker framework problem?
by Bình Dương, Tran 22 Jul '18

22 Jul '18

Dear Sir, I have a checker from problem set of Northern Eurasia Programming Contest 2017 ( I uploaded it to my google driver and share it below ). The checker had been compiled and packaged into a jar file. I wrapped it by a run script. When I apply this checker (compare checker type) to the problem and trying to evaluate a submission, the following error arose: ==================== [Jul 11 04:58:49.719] testcase_run.sh[48059]: Comparing failed with exitcode 0, compare script output: [Jul 11 04:58:49.731] judgedaemon[47929]: error: Unknown exitcode from testcase_run.sh for s801, testcase 1: 1 ==================== I don't know how to fix it or make the checker work properly, please help me to do that. P/S: Because the original file has been blocked by google security service, I changed its extension to .zi, please rename it back to .zip and check. You can download the checker file from: "https://drive.google.com/open?id=1sV4UDRFS5i3c8HVRqA3UJiLLvumUx8GK" Regards, -- [Điện thoại: (04) 37687717 – Máy lẻ: 100]<http://Email:%20linhpt@fpt.edu.vn/> Thanks & Best regards ------------------------------------ TRẦN BÌNH DƯƠNG Giảng viên bộ môn Công Nghệ Phần mềm Trường Đại học FPT Tel: (04) 37687717 – Máy lẻ: 104 Mobile: 0936 168 165 Email: duongtb(a)fe.edu.vn<mailto:duongtb@fe.edu.vn> _______________________________________________________________________ The information in this e-mail and any attached files are CONFIDENTIAL and may be legally privileged or prohibited from disclosure and unauthorized use.

Swap for judgehosts
by Wim de With 07 May '18

07 May '18

Hello, I was reading the adminstrators manual and I have a question about the section about setting up a judgehost: https://www.domjudge.org/docs/admin-manual-3.html#ss3.7 It recommends the 'swapaccount=1' kernel parameter, but that made me wonder if you actually want swap on a judgehost. I'm not fully familiar with how Linux processes and swap work in detail, but say a judgehost is judging a random submission while the RAM of the host is almost exhausted. If the memory is swapped to disk to clear space for the memory allocated by the submission, doesn't that potentially heavily impact the run time of the submission? And if that's true, wouldn't you see a TIMELIMIT that is not fully justified, because while you might not exceed CPU time, you will exceed wall time? I hope you can shed some light on this. Regards, Wim

How to upgrade domjudge system from 5.1.3 to 5.3.2 without changing current data
by Bình Dương, Tran 13 Apr '18

13 Apr '18

Hi all, I'm managing a domjudge system ver 5.1.3, and I hold many contests with lots of problemsets and students works there. Now I installed a new judgehost with domjudge ver 5.3.2, and I coped with this error while connecting judgehost with the legacy domjudge server via APIs, I think that it's an incompatible error. "Configuration variable 'diskspace_error' not found." I would like to solve this problem, but I don't know how to? BTW, I also want to upgrade the domjudge server system, but I don't know the procedure must be followed? Regards

Differences between master and ICPC-live
by Tobias Werth 28 Mar '18

28 Mar '18

Hi, I want to get rid of the ICPC-live branch as soon as possible after the finals. I also think that we should do this first before we do any further symfony migration. This is a list of the differences to get the discussion started (I probably missed some things): 1) entry_point handling Options: a) add a global configuration b) always require an entry_point if the language itself requires an entry_point c) detect entry_point on domserver I would go with b). By default we can use compile scripts that auto-detect and configure languages as such. In a setting primary/shadow setting, we can require entry points as we do now. 2) Minor things: - Pause contest countdown / starttime_enabled - tsv/yaml import scripts - results/tsv export scripts There's no reason to disable these. 3) external IDs / external results - have only one database scheme, i.e. include columns for external_ids and _results - why don't we always use the contest shortname as ID in the API? - can we drop the expected result in favor of external results? (note that we didn't do a comparison on testcase level in the past but might want to do it in the future) - external_ids and _results can be used even in primary mode where we could fetch the results from the secondary 4) display test case results in submission lists Options: a) make it configurable (either per contest or globally) b) always display them (for jury of course) I don't think the test case results clutter the submission page too much, so I would just keep them always on for simpler code. 5) removed time intervals The code in calcContestTime looks fairly simple. The UI only affects the contest page. Did I miss anything? Best, Tobi

We're currently changing to using Symfony in master, and there we didn't setup LDAP authentication yet. However, up to version 5.3 you can configure to authenticate users against an LDAP server. See etc/domserver-config.php, the LDAP authentication method and related settings. The authentication code lives in lib/www/auth.php. We also have an option to allow users to self-register with DOMjudge, see the configuration settings in the admin web interface. I'm not the most familiar with this code, so others might want to step in with more details. Best, Jaap

Hi all - I'm having trouble writing the most recent live ISO file to a USB drive.

Does it matter what format the USB is in before I run the bzcat operation? I didn't think so... [image: Inline image 1] Thanks (and I apologize if this has been answered before)! Matt Fahrenbacher

[Dj] CPU time vs. Wall time
by PEDRO PABLO GOMEZ MARTIN 02 Mar '18

02 Mar '18

Hello, I've been using DOMjudge since the old 3.x days, and in the last few years I've been applying a couple of changes in my new installations to overcome some problems that, IMHO, have arisen with the new versions. I want to share them in case they are useful for others, they can be considered to by applied to the mainstream version, or to get feedback if I've been doing something wrong. The first one is regarding CPU vs. wall limit times. When runguard is invoked from testcase_run.sh, the script provides it with the parameters --cputime and --walltime. Years ago the walltime was set with 2*${TIMELIMIT}. But at some point in the past, the format of $(TIMELIMIT) was changed to "<soft>:<hard>" and that expression stop working. The script was updated and now the --walltime is exactly the same as --cputime. I experienced difficulties because of that some time ago, because runguard reported Time Limit due walltime exceeded even when the CPU limit was far to be reached. This occurred when the server was suffering a high load, or the first time a big testcase had to be recover from the database. My solution has been to change that script (testcase_run.sh) so the walltime is scaled up. The official script is: runcheck ./run testdata.in program.out \ $GAINROOT "$RUNGUARD" ${DEBUG:+-v} $CPUSET_OPT \ ${USE_CHROOT:+-r "$PWD/.."} \ --nproc=$PROCLIMIT \ --no-core --streamsize=$FILELIMIT \ --user="$RUNUSER" --group="$RUNGROUP" \ *--walltime=$TIMELIMIT --cputime=$TIMELIMIT \* --memsize=$MEMLIMIT --filesize=$FILELIMIT \ --stderr=program.err --outmeta=program.meta -- \ "$PREFIX/$PROGRAM" 2>runguard.err and my change modifies the --walltime line: ... --walltime=*$((4*${TIMELIMIT%:*}))* --cputime=$TIMELIMIT \ ... Note that I'm using a factor of 4 instead of 2 used long ago by DOMjudge. This change works for versions up to 5.1.x. Since DOMjudge 5.2 timelimits can be float values, and my expression is not working anymore. Now bc is needed in order to be able to use float arithmetic: ... --walltime=*$(echo "scale=2;4*${TIMELIMIT%:*}" | bc)* --cputime=$TIMELIMIT \ ... This last patch is due to my college Joan Rodríguez, and adds a new package dependence (in judgehosts) with the bc program. The second change that I've been applying to DOMjudge is in runguard itself, and it is also related with CPU time, although now I'm unsure about the reasons causing my problems. Sometimes, when evaluating java submissions, instead of Time Limit verdict we got Run Error. We solved this issue increasing the real cputime hard limit in runguard. The official runguard adds one second to the CPU time limit, and for some reasons that seems to be insufficient in some cases so we change it to add 2 seconds. In the runguard.c source code: if ( use_cputime ) { /* The CPU-time resource limit can only be specified in seconds, so round up: we can measure actual CPU time used more accurately. Also set the real hard limit one second higher: at the soft limit the kernel will send SIGXCPU at the hard limit a SIGKILL. The SIGXCPU can be caught, but is not by default and gives us a reliable way to detect if the CPU-time limit was reached. */ rlim_t cputime_limit = (rlim_t)ceil(cputime[1]); verbose("setting hard CPU-time limit to %d(+*2*) seconds",(int)cputime_limit); lim.rlim_cur = cputime_limit; ^ lim.rlim_max = cputime_limit+*2*; | setlim(CPU); ^ | } +---------- CHANGED This change avoids those false RUN ERROR verdicts we sporadically suffered. Unfortunally I cannot provide a way to replicate the error because it is quite erratic. As judgehosts we use virtual machines, in case that is important. Thank you for your great DOMjudge. Best regards, Pedro Pablo

New team and public UI
by Thijs Kinkhorst 14 Feb '18

14 Feb '18

Hi all, I've just committed to master my attempt at renewing the Team and Public UI's. In my opinion the DOMjudge interface looks a bit dated and could use a fresh coat of paint. Let me know what you think. Note that you need to run composer (see https://www.domjudge.org/docs/admin-manual-10.html#ss10.1) when updating from git sources. It's definitely not "done" in the sense that it could likely be made even better, but I think it's an improvement over what we had. Because of all the developments going on I purposefully kept to relatively minimal changes to get it done (i.e.: no rewriting to templating systems yet, nearly all logic unchanged, scoreboard layout untouched). There's room for more cleanup and refactorng, especailly if we want to change the Jury interface aswell. And if we want to move to proper templating via Twig for the entire interface. That is appropriate for after 6.0 I think. Cheers, Thijs

Do installing from https://www.domjudge.org/icpc-kotlinc_1.1.4-3~icpc_all.deb, will install kotlin to the chroot environment? Do I need any more steps to make it available to chroot enviroment? Just installing the package above is not enough. What you need to do is to install the package _inside_ the chroot. The steps you need to take are (roughly, it may vary slightly depending on your environment): - copy icpc-kotlinc_1.1.4-3~icpc_all.deb somewhere into your chroot - enter the chroot: sudo chroot /chroot/domjudge (or whatever path you build it at) - install the package there: dpkg -i /path/to/icpc-kotlinc_1.1.4-3~icpc_all.deb - if dpkg complains about missing dependencies, run 'apt-get -f install' or install them and then try again - exit the chroot and test if it works You might need to bind mount /proc, /dev, and/or /dev/pts inside the chroot to make apt-get work. See the domjudge chroot-start-stop.sh file for examples how to do so.

[Fwd: Re: Kotlin Problem]

Thanks for the quick reply again, Sir. I was supiscious about kotlin is not installed in chroot enviroment too but i have no idea how to install them at chroot enviroment. Before you reply, I have managed to make kotlin work by compiling using kotlinc to make java executable (jar), and finally running the program using java and -jar parameter on addition other java parameter. But I worry that it will create future unknown problem. Anyway , I need more guidance to install kotlin at chroot mode. Do installing from https://www.domjudge.org/icpc-kotlinc_1.1.4-3~icpc_all.deb, will install kotlin to the chroot environment? Do I need any more steps to make it available to chroot enviroment?

Dear Domjudge - Developers, Hello again, I have problem to integrate Kotlin compiler in judgehost. For information, I'm using ubuntu 16.04 and I was installing kotlin from sdkman. But when compiling, it seems that domjudge cannot find kotlinc and kotlin. I have try to move kotlinc and kotlin to /bin/ directory. It seems to solve kotlinc problem, but domjudge still cannot execute kotlin. When I try to go to directory where /testcase001/execdir/program resides, and then execute it myself.

Until December 11th, there was a "domjudge" user on Docker Hub hosting two images: https://hub.docker.com/r/domjudge/domserver/ https://hub.docker.com/r/domjudge/judgehost/ Since December 11th this user seems to have disappeared from the site. Does anyone know who maintained the images and why they are now gone? They have been working just fine for me. Sorry if this list is not the appropriate place for the question.

Perhaps you can give more details on the compile > error or give me admin access to your domjudge installation? Tobi, THANK YOU so much for jumping in to help, and thanks to Keith as well. Fixing the permissions on the judging directory (/opt/domjudge/judgehost/judgings) got us back to where we were before, and we made some quick adjustments to the Apache configuration that seemed to help. I can't say for certain if that fixed everything because at that point the contest was close to over (we extended it by one hour) and some teams may have taken off already if they were not in the running. However, we were ultimately able to judge everything and complete the contest (albeit with contestants programming with no feedback for two hours). We in Southern California (that means me) would like to take you up on your offer for assistance with root cause analysis. I have the contest server sitting next to me here at home and can provide anything you might want that would help with troubleshooting. Please let me know what the best way will be to proceed. I owe the DOMjudge team big-time. Marc

See https://www.domjudge.org/docs/admin-manual-3.html#ss3.7 We typically start the judgedaemon with -n <core-id>, e.g. -n 0 (even when running a single judgedaemon), then you need to create domjudge-run-0.

CTD File Testing
by Bryce Sandlund 24 Oct '17

24 Oct '17

Hi, I am preparing a problem set for Kattis and thought I'd try making a CTD file input format validator. I found the CTD GitHub and have been following along with the README and language specification. I'm currently a little frustrated. By running Kattis problemtools, I can determine if my ctd file compiles and accepts test cases. Currently, I cannot get SPACE EOF to accept a file with a single space, or INT(1,10000) EOF to accept a file with a single integer. I can get EOF to accept an empty file. Clearly something silly is going on, and it'd be much easier to see by a more instructive error message than accepting or not-accepting. So I thought I'd try to compile the ctd file my self, or run it myself and see if there is more error output. It looks like there's no instructions on how to go about doing that in the README on GitHub. I'm also not sure if the error messages would be more informative. I am suggesting such instructions be added to the README and that such a command would be able to give me a more informative error. Bryce

JAVA cgroups help
by 이정진 10 Sep '17

10 Sep '17

Hi. I set cgroups for java, but it does not work and I have some ask. I proceeded to install cgroups as follows the manual 3.17. ======= sudo apt-get install libcgroup-dev sudo edit /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1" sudo update-grub sudo reboot and I checked the cmdline. cat /proc/cmdline print is BOOT_IMAGE=/boot/.. ~~ ro quiet cgroup_enable=memory swapaccount=1 next sudo ./configure >>During the execution of this command, I confirmed the following message. *use Linux cgroups...: yes sudo make build sudo ./misc-tools/create_cgroups and then, I run judgedaemon. However, judgedamon displays the message "Not using cgroups". ======== Can you tell me where I made the mistake? thanks.

Using the integrated event feed
by Phúc Khang Nguyễn 09 Aug '17

09 Aug '17

Hi, I'm currently running DOMjudge v5.1.3. Recently, I wanted to use the Resolver in the ICPCTools. I saw the integrated event feed in /www/feed but I really don't know how to use and I can't find the documentation of the event feed. I'm not a PHP user so I can't come up with any solution on my own. Could you show me how to set it up in order to use the Resolver or link me to the documentation? Best Regards, Khang *Nguyễn Phúc Khang* Mobile: 0931 633 723 Trường Đại học Khoa Học Tự Nhiên, ĐHQG-HCM

Out of range value for column 'totaltime'
by Richard Lobb 13 Jul '17

13 Jul '17

Hi guys We're running domjudge 5.1.1 and for some reason I don't understand we're being plagued this year by errors like the following: error: Error while executing curl POST to url http://domserver.cosc.canterbury.ac.nz/api/judging_runs: http status code: 500, response: error: SQL error, Error#1264: Out of range value for column 'totaltime' at row 1, query: 'REPLACE INTO scorecache_public (cid, teamid, probid, submissions, pending, totaltime, is_correct) VALUES (24,1403,222,1,0,-15780,1)' They occur when you set up a contest with an early opening date for testing purposes, make submissions then, later, move the opening date forward to the correct time. Refreshing the cache then results in those errors (because the submission time relative to the contest start time is negative), crashing the judgehosts. I've been solving the problem by marking the early submissions as "IGNORE this submission" or by hacking at the database directly but neither of those workarounds is very satisfactory. I don't recall having these errors last year, and nor do I think I've upgraded domjudge system since then, though I might have upgraded the OS? Any suggestions for a better work around, please?

Checktestdata as EDSL
by Jeroen Bransen 30 May '17

30 May '17

Hi all, Checktestdata is a nice DSL and has proved helpful in many situation, but from the moment I used it I was missing features and wondering why it wasn't implemented as an EDSL (Embedded Domain Specific Language). Now, many years later, I've finally found some time to create it. I've implemented a little library in Haskell, and as a sneak preview I've taken the interception problem from NCPC 2016 as referenced to in [1] and attached it. The first question is: where shall I put the sources to the library? Somewhere in the checktestdata repository (and if so, where), or maybe create a checktestdata2 repository? Let me give a little more information on why I think an EDSL is a good idea here, and why I choose for Haskell (other than my background): + With an EDSL, you get so much for free from the underlying language, such as (typed) variables, all sorts of abstraction mechanisms, compiler optimizations, etc. For example, some testdata script may consist of some repeated parts, which in an EDSL can simply be given a name to get rid of the duplication. + Compiler optimizations, which of course also exist for C++ in which checktestdata is built now, don't only optimize the checktestdata runtime, but also the script itself since it is just a program and not some custom script anymore. Especially with a functional language such as Haskell this means definitions of primitives can be inlined and whole parts of the script may get fused to a very efficient version. + Maintainability: my library is now +- 200 LOC, including docs and empty lines, and contains quite a lot of the checktestdata language already. Because Haskell has many well optimized parsing libraries, we get a lot for free, and only have to create a nice generalization for this particular use case. + Efficiency: the current checktestdata is just too slow, as mentioned in [1]. As a reference, on my machine the checktestdata script for interception 09.max_ans.in takes 35.5s, the python script takes 2.2s, and the attached version only 2s. And I haven't done anything to optimize specifically for this case, I've just translated the ctd script to the syntax of my EDSL. + With this, the script can do more than just checking the syntax. I.e. when the problem specifies that it contains a connected graph, one can check the syntax, but also the connectedness of the graph, while still separating concerns, i.e. the syntax of the input can be separated from the semantic checks, but the semantic checks don't need to come in a separate program which also has to read the input again, like we should now. All can be combined naturally. + Create your own combinators: the primitives can be easily combined into more complex combinators which you can then reuse. I.e. think of a 'point2d' combinator that reads two space separated integers. - Haskell Platform needs to be available, this is easy on all major OS, but is a quite large dependency. Then again, GCC and Boost are large as well, and are less Windows-friendly. - Slighly different syntax: although Haskell is quite liberal in its syntax for EDSL's, users have to get used to particularities of the language/ - Data generation is not easily possible, if not infeasible. There should be some way of embedding the language to make this possible, and this is actually what I've been working on for the past few years when thinking about this problem, but since we mostly use it for checking data I went with a monadic embedding which is very easy for data checking. - Backwards compatibility: parsing existing scripts and running it with the new backend is not going to be easy. I don't expect show stoppers, but it definitely won't be as efficient as writing scripts within the language because of variable bindings. I need to work on this a bit to be sure though. That's it, of course my libary is not done yet (no good error messages, no regex yet), but it's a proof of concept that is already usable for simpler problems. I hope to convince you that this is the way to go, and to get some ideas to create the POC into a working tool. Also, suggestions on 'interesting use cases' are welcome, the interception is a nice one but I am sure there are many more problems for which the standard checktestdata just not works. Yours truly, Jeroen [1] https://github.com/DOMjudge/checktestdata/issues/3

Storing participant program in execdir after judging is complete
by Parth Mittal 28 May '17

28 May '17

Hello We run an instance of domjudge for our university courses, which has a lot of submissions (the judging run table has almost a million rows now). I was exploring ways to reduce the disk usage of the judge, and I found that in the directory for every judging run, we store a copy of the executable under execdir under every testcase. Each executable is > 1 MB, and when this multiplies with number of test cases * number of judgings, this becomes very large in our use case. Is there a reason why the executables are stored after judging is complete? Thank you Parth Mittal

Dependent problems
by Solal Pirelli 18 Apr '17

18 Apr '17

Hi all, At the Helvetic Coding Contest - as its name implies, Switzerland's largest programming contest - we patched DOMJudge to add support for hiding problem statements until another problem is solved. For instance, if C depends on B and B depends on A, teams are forced to first solve A, then B, then C. This year we had 5 such chains, for a total of 15 problems. This has two advantages: - It forces beginners to solve easy problems first, ensuring they'll solve a few problems and have fun rather than picking a hard problem whose difficulty is not apparent and getting stuck on it for hours. (This looks like a problem that should be solved by educating users, but as any software engineer knows, that is all but impossible :) ) - It allows us to have a bunch of problems on a common theme, where in a few cases the harder one's statement is simply "like the easier one, but with much larger bounds on the input" without allowing teams to solve the hard one first and then submit that solution to the easier one. More problems, less work for problem creators. Thus our contest is suitable for both beginners and experts (even if beginners don't have a chance of actually winning, they enjoy it). I recently rewrote that patch on top of the master branch of the DOMJudge repo, it's quite small (about 40 modified lines). Is this something DOMJudge users are interested in? Should I open a PR? Cheers, Solal Pirelli

Re: [DOMjudge-commits] Checktestdata branch master updated.

Hi Jeroen, Could you add a description or Makefile documenting how to build this? I tried to do so by installing cabal, and the required packages, but failed. I think I didn't have exactly the right versions, and even then, the Setup binary complained that none of the packages were available.

How to add problem to a contest
by Umair Khan 09 Dec '16

09 Dec '16

Hi, I know this seems to be a very trivial question, but I'm not getting from where do I add a problem to a contest. I have created a problem and also a contest. The contest page shows that no problems have been added to it. What am I missing? Thanks in advance, Umair

Question about Domjudge
by tfg computer 04 Nov '16

04 Nov '16

Dear Sir, Thank you very much for developing Domjudge system. I have a problem archive as attachment "test.zip". I summit right code as attachment "test.cpp". But the Domjudge system always shows "TIME LIMIT", or "PENDING". I try to run the code in windows and linux, the code works well. I still can not understand what wrong it is. Could you please help me show what wrong it is and how to solve it? Thank you very much for your help. Sincerely, Janet

Problem Import on Version 5.1.2?
by Marc Furon 10 Oct '16

10 Oct '16

I installed version 5.1.2 of DOMjudge locally for testing. I went to test the problem import process, but I do not see the problem import option on the problem page when logged in as "admin". I can add a problem manually, but I wanted to test the import functionality. Did something happen to this feature? Or is there some type of problem with my installation? Any suggestions you can provide will be appreciated. Marc

Multiple simultaneous contests
by Cheng, Howard 08 Oct '16

08 Oct '16

Hi, With the current version I can run multiple contests simultanenously. But I have not found a way to limit a certain subset of users/teams to one contest (i.e. I don't want users to show up on the scoreboard of the contest they are not involved in). Is there a way to do so?

Hi folks, On the DOMJudge - Download page at https://www.domjudge.org/download you have an instruction for adding your repository GPG key to APT but the URL in the instruction is incorrect. Furthermore, the pipe command requires sudo but the curl command does not. The command as currently displayed is: sudo curl -o - https://domjudge.org/repokey.asc | apt-key add - It should be: curl -o - https://www.domjudge.org/repokey.asc | sudo apt-key add - Hope this helps someone.

checktestdata regex problem
by David Venhoek 26 Aug '16

26 Aug '16

Dear checktestdata maintainer(s), I tried installing checktestdata today on ubuntu 14.04.5, and noticed that the REGEX command is not properly functioning. Running make check reveals a failure in testcase 14, and manually running said testcase results in the following unfortunately rather unhelpfull message; terminate called after throwing an instance of 'std::regex_error' what(): regex_error Aborted (core dumped) Is this a known issue, or are there any obvious causes I could check? Kind regards, David Venheok

Hello , Thanks in advance. Please i need help. About your answwer:(Japp) "The REST API is an "application programming interface". The web method does not use it, but "talks" to the webserver directly. Also you don't need libcurl, but this is just one (easy) way of writing code to access the REST API" My problem is a bad request 400, I understand that the problem is that i send the parameters not correctly format and for this problem submmit post rest api doesn,t work. Please if someone know the correctly form to send the parameters, please wrote to me or send me an code example. Now i am going to put two methods make for a friend and me, this methods don´t work, we recieve a bad request 400, he and i are thinking the problems are some parameters that post doesn,t undesrtand,( http://localhost/domjudge/api/submissions POST) methods ------------------------------------------------------------ private void testConsumerPOST(String array, String nombreProblema, String languageId, String contest_id) { String servletURL = "http://localhost/domjudge/api/submissions";

THANKS FOR THE DOMJUDGE REST API!!!
by JAVIER BARRIUSO CAMARERO 08 Aug '16

Hi there, Your API REST is real good, and I have almost finished the implementation of a single Java client to consume most of your methods, but I have found only one problem with the submission files POST method. Due to technical restrictions Im not allowed to use CURL so I have to use HttpURLConnection and Im receiving constantly a response with 400 Error. After reading the PHP definition I have wrote this quite common Java method: .... private void testConsumerPOST(String array, String nombreProblema, String languageId, String contest_id) { String servletURL = "http://localhost/domjudge/api/submissions"; URL servlet = null; try { TrustManager[] trustAllCerts = new TrustManager[]{ new X509TrustManager() { public java.security.cert.X509Certificate[] getAcceptedIssuers() { return null; } public void checkClientTrusted(X509Certificate[] certs, String authType) { } public void checkServerTrusted(X509Certificate[] certs, String authType) { } } }; SSLContext sc = SSLContext.getInstance("SSL"); sc.init(null, trustAllCerts, new java.security.SecureRandom()); HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory()); // Create all-trusting host name verifier HostnameVerifier allHostsValid = new HostnameVerifier() { public boolean verify(String hostname, SSLSession session) { return true; } }; // Install the all-trusting host verifier HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid); servlet = new URL(servletURL); HttpURLConnection servletConnection = (HttpURLConnection) servlet.openConnection(); // AUTENTICACION String userpass = "admin:admin"; String basicAuth = "Basic " + new String(new com.sun.org.apache.xerces.internal.impl.dv.util.Base64().encode(userpass.getBytes())); servletConnection.setRequestProperty("Authorization", basicAuth); servletConnection.setRequestMethod("POST"); servletConnection.setDoOutput(true); servletConnection.setDoInput(true); OutputStreamWriter out = new OutputStreamWriter(servletConnection.getOutputStream()); ObjectMapper mapper = new ObjectMapper(); Map<String, Object> data = new HashMap<String, Object>(); data.put("code[]", array); data.put("shortname", nombreProblema); data.put("langid", languageId); data.put("contest", contest_id); out.write(mapper.writeValueAsString(data)); out.flush(); if (servletConnection.getResponseCode() != HttpURLConnection.HTTP_CREATED) { throw new RuntimeException("Failed : HTTP error code : " + servletConnection.getResponseCode()); } BufferedReader br = new BufferedReader(new InputStreamReader( (servletConnection.getInputStream()))); String output; System.out.println("Output from Server .... \n"); while ((output = br.readLine()) != null) { System.out.println(output); } out.close(); } catch (MalformedURLException ex) { Logger.getLogger(PostSubmission.class.getName()).log(Level.SEVERE, null, ex); } catch (ProtocolException ex) { Logger.getLogger(PostSubmission.class.getName()).log(Level.SEVERE, null, ex);

Error during dj-setup-database
by Malcolm Corney 04 Aug '16

04 Aug '16

During domjudge 5.1.2 setup on Ubuntu 16.04 with MySQL 5.7.13, PHP 7, Apache 2.4.18 I am getting the following error after executing: sudo /opt/domjudge/domserver/bin/dj-setup-database -u root -r install Database credentials read from '/opt/domjudge/domserver/etc/dbpasswords.secret'. Enter password: DOMjudge database and user(s) created. Enter password: ERROR 1292 (22007) at line 744: Truncated incorrect datetime value: '2016-01-01 08:00:00 UTC' There is no line 744 in dj-setup-database. Searching for ERROR 1292 (22007) does not bring me any closer to a solution. I continued with the installation and everything seems to work OK. There are no example contests, users, teams, problems when I do so. Running: sudo /opt/domjudge/domserver/bin/dj-setup-database -u root -r status indicates that the database check was successful. Any hints here? Thanks, Malcolm Corney

Fedora 24 and Submit Client
by Marc Furon 02 Aug '16

02 Aug '16

I am running Fedora 24. I am trying to install DOMjudge 5.1.2 to start preparing for the next regional contest. When I try to run "configure", it gives an error after checking for jsoncpp/json/json.h. This is because it does not exist. json/json.h does exist. When I look at the jsoncpp-devel package, it does not have any files that are in a directory named jsoncpp. The documentation states that json/json.h should be used. I will skip the submit client for now, and we may decide not to use it at all (we have not used it in the past). However, it would be nice to get it to work. I do not have a Debian system handy to see if the include files are different there. Does anyone have suggestions for a resolution to this problem? Regards, Marc

OCaml support
by Parth Mittal 19 Jul '16

19 Jul '16

Hi I tried to add OCaml to the languages, so the compile script I used is: #!/bin/sh # C++ compile wrapper-script for 'compile.sh'. # See that script for syntax and more info. DEST="$1" ; shift MEMLIMIT="$1" ; shift MAINSOURCE="$1" ocamlc -o "$DEST" "$@" exit $? And for run, I left it as default script. But when a submission is judged, it exits with a RunTime Error The Runguard output follows: /home/foobar/domjudge5.1/judgehost/bin/runguard: cannot start `/testcase001/execdir/program': No such file or directory Try `/home/foobar/domjudge5.1/judgehost/bin/runguard --help' for more information. I tried to look for the file, and it does exist, and works like an executable, so I am not sure what is going wrong. For completeness, I also tried to echo the variables being passed to run, and the output in my temporary log file shows sudo -n /home/foobar/domjudge5.1/judgehost/bin/runguard -P 3 -r /home/foobar/domjudge5.1/judgehost/judgings/foobar-3/endpoint-default/c131-s68948-j78769/testcase001/.. --nproc=50 --no-core --streamsize=40000 --user=domjudge-run-3 --walltime=1:2 --cputime=1:2 --memsize=4096000 --filesize=40000 --stderr=program.err --outmeta=program.meta -- /testcase001/execdir/program Please advise on how to proceed.

[Domjudge] Selectively allowing languages per problem in a contest
by Ambar Pal 27 Jun '16

27 Jun '16

Hi I am trying to set up a contest where I have 4 languages available for the participants along with say 4 problems. Is it possible to configure domjudge in such a manner such that the partipants can solve Problem 1 only with Language 1, Problem 2 with either Language 1 or Language 2, Problem 3 with only Language 3, and so on. I was initially thinking that per problem run scripts would be the solution for this, but turns out it is not the case. I would highly appreciate any help in this regard. Thanks a lot Ambar Pal

Judgedaemon binding
by Parth Mittal 06 Jun '16

Hi We’re trying to run domserver an judgedaemons on the same machine (a 6 core VM). My plan so far is to use the kernel flag isolcpus to reserve 4 cores for the judgedaemons. My question is that when we bind a judgedaemon using judgedamon -n does it set the affinity to the right mask by itself or do I need to do something? Thanks Parth Mittal PS. I’d also appreciate any alternate approaches that you have in mind.

Scoreboard cache refresh fails
by Parth Mittal 29 May '16

29 May '16

Hi We have this one giant practice session contest running all the time, and we want the scoreboard to work here. So the scoreboard.php when called uses more than 128M memory, and I increased the limit in /etc/php5/apache2/php.ini to 512M, so now that works to render the scoreboard. However, when I do scoreboard cache refresh, we still run out of memory, so I assume it uses a different php.ini? Where can I edit this file? Thank you Parth Mittal

Error after upgrade
by Parth Mittal 29 May '16

29 May '16

Hi guys We were running domjudge version 4.0 on Ubuntu 12.04, and over the weekend decided to upgrade 5.1. (I’m not the original maintainer, he has graduated from our institute). So the database upgrade scripts ran mostly fine. I had to change the shortname column fill line (in 4.0 -> 5.0) UPDATE `contest` SET `shortname` = CONCAT(`cid`, UPPER(SUBSTR(REPLACE(`name`, ' ', ''), 1, 10))), `public` = 1; since previous version did not generate unique value for contests with long common prefix. Further I commented out the line to upgrade to support full unicode (in 5.0 -> 5.1) because it refers to a file that I couldn’t find, and gave an error. So after this DB upgrade was complete. Now for Apache conf, since we are still on 2.2, I didn’t find the a2enconf, and found in /etc/apache2/conf.d a symlink to the previous apache.conf. So I updated the symlink, and then commented out the apache2.4 parts of the new file. Is there something else I need to do? Because when I run, I get 500s in the web browser. I also tried to look at the apache log file, and I got these errors Sun May 29 11:23:10 2016] [notice] Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.23 with Suhosin-Patch mod_wsgi/3.3 Python/2.7.3 configured -- resuming normal operations [Sun May 29 11:23:17 2016] [error] [client 192.168.1.99] File does not exist: /var/www/contest [Sun May 29 11:23:19 2016] [error] [client 192.168.1.99] PHP Parse error: syntax error, unexpected '[' in /home/foobar/domjudge5.1/domserver/lib/www/print.php on line 126 Could you please advise on how to fix? I have a backup of the database from the 4.0 install, so I can even start the process again if I did something wrong earlier, but I would prefer not to do that since the backup is ~100 GB (because of large number of submissions). Thank you Parth Mittal

Run over 8 judgedaemon on server

Hi, I have a problem when I try to run multi-core judgedaemon. I followed your document. I setup cgroups, edit etc/cgroup-domjudge.conf: -- Change cpuset.cpus = 0 => cpuset.= 0-22; I also add file misctools/create_cgroups to /etc/cgconf.d/cgroup-domjudge. After that, I check /cgroup/cpuset/domjudge/cpuset.cpus => Output is 0-23. I also build runguard after I config cgroups. But I only can run 8 judgedaemon. From judge 9th, if it compile any code, I will receive this error: Compiling failed with exitcode 255, compiler output: /domjudge/judgehost/bin/runguard: illegal user specified: 7809 Try `/domjudge/judgehost/bin/runguard --help' for more information. I set all user is user that I run domjudge. But judge 8 judge can compile well. Please help me! Thank you!

In that case you should raise the memory limit to something quite high. I'd suggest to start with 2GB and increment this to 2.5 and 3 GB if it doesn't work yet. That's because the Java VM pre-allocates a lot of memory. With cgroup support this is not an issue, but without you have to add that overhead to the memory limit.

To what size did you raise the memory limit? Try to raise it at least to 2GB if you're not using Linux cgroups. Unfortunately, the way that memory is reserved by the JVM and counted (using resource limits) by Linux often requires such huge amounts. Therefore we strongly recommend using cgroups: that measures only memory really used by the JVM and requires more reasonable overhead.

Changes from Munich
by Stefan Toman 06 Mar '16

06 Mar '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear DOMjudge developers, first of all thank you for writing DOMjudge. We are using it at TU München, Germany, for many courses and competitions. Having more than 100 contests and 50.000 submissions by 1000 teams we changed many parts of the system and created a fork of your project. We would like to contribute our changes to DOMjudge if you are interested in them. You can see our website for instance at https://judge.in.tum.de/conpra (other sections are available at the top left corner of every page). The sources we use are available at https://git-judge.in.tum.de/icpc/tumjudge. We will create merge requests in case you are interested in our changes. We would do some things a little different when we don't work in our fork. For instance, we created new css and javascript files to avoid conflict when merging your changes. These are the main features we added to the system: * a modern layout based on bootstrap with a nicer menu bar and form controls * teams can also view, download and edit their submissions as jury members can do it already * an overview of points throughout all contests a team participated in, grouped by similar contest names * bonus points can be awarded to teams for individual problems and contests * the statistics page generates some LaTeX commands to include detailed statistics into solution slides * problems have additional fields author, difficulty, topic and source and there are filters for these fields * write access to user and team accounts can be restricted for admins (We run several DOMjudge instances for several courses since we don't want lecturers of different courses to adjust the system as they need it. User accounts are shared via a MySQL replication, which makes user data read-only for all but one instance, all other data, including roles, is not shared.) * links in the menu are customizable in the settings * scoreboards can be shuffled in case you don't want to reveal which problems were solved (see contest 6 at the link given above for an example) * the judge instances are integrated into our website, the news system and the account system of the university (probably nothing that somebody else would need) We also created a framework to create random test data for problems from some seeds. This allows us to run failing submissions of teams on small random inputs until we find one that makes their submission fail. That way, we usually find much smaller inputs that are easier to debug. These scripts can be called from the jury backend and the output is also included into the backend. We hope there are some changes that may be interesting for you. If this is the case please tell us. We can tell you more about what we did there and would like to contribute the corresponding changes. Best regards, Stefan -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBAgAGBQJW2BppAAoJEBKwZA1x2vm6qNUH/RyzQ5BjZdbkkHnRMAiELQHH NTfeSK8Sl5BXXYNPyQ4YmVR3o6NrcCkh5hVzkJzUb7e9Zw+2FRhBVA5OK0MxmOcr syOCXdQXuITNPYdbn4i5gJwdjvaKJmR0r/IFd7kyfuBG4EdbDjo1Au52IxD10p8H pEpa6wwcsuW1jKk78c/EQ8cUnL0uw8T/2KtAvsHh2/siKOecZscZw7/wA3hKHUPx gK4e9wjZ6xbA2Di8HH0zreL8OBPhLH2qNkLdKuzVhYKoFzVXM2UUWMOXN4WQVq0x XH2DfXzoCOC2iWTEeJ7ZVXg0l0isl6LfzFQ5Mbnkd7PmiEBhYSChJkd/cum30e4= =gH0q -----END PGP SIGNATURE-----

moving to a PHP framework
by Jaap Eldering 05 Feb '16

05 Feb '16

Hello all, During/after the hackathon of 24 January the issue was raised that the codebase of DOMjudge is getting more and more complex and that it would be a good plan to move to a PHP framework to separate code and HTML layout via templating and using an ORM to abstract away the database. The discussion was initiated in a github issue here: https://github.com/DOMjudge/domjudge/issues/198 and I'm attending everyone here to it. If you have any experience with PHP frameworks such as Symfony, Laravel, or others, feel free to chime in, or even help with some initial testing to determine which framework to choose. Jaap

Output limit
by Br. Anand Shenoi 19 Dec '15

19 Dec '15

Hi All, What is the difference between the output limit in the global settings and that in the problem wise setting? When we set the Output limit for a specific problem, it gives TLE. If the output limit for the same problem is not set, it never exits from the memory. the status shows "JUDGING". It means, the global output limit is not being considered by DOM. Can anyone help please?

Time specific for a problem & Global time limit
by Br. Anand Shenoi 14 Dec '15

14 Dec '15

Guys, A doubt: There is a "time limit" for each problem. There is a "time limit overshoot" in Configuration Settings. Does it mean that if we set the "time limit overshoot" as more than the maximum time limit for one of the problems in the contest, it will affect the others with the lower time limit? For example: Contest 1 has 5 problems 4 problems have 1 sec time limit. Rest 4 has 4 sec time limit. And let us say one of the submissions for 1 sec problem set goes into infinite loop. Will the problem exit as per 1 sec time limit for that problem or will I wait for the 4 sec global "time limit overshoot"?

Hi, I cannot log in with the default data admin/admin http://isc.unsaac.edu.pe/cuscontest/public/login.php but when I do this through curl it seems to be working fine: curl --data "login=admin&passwd=admin&cmd=login" http://isc.unsaac.edu.pe/cuscontest/public/login.php what could be the reason for this behaviour, hope you can help me. BTW it was working fine before, I cannot realize why it suddenly took this behaviour, the domjudge version is 4.0.5 and I'm using this version of ubuntu. ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ lsb_release -a No LSB modules are available.

Has anybody tried to embed source code editor with DOMjudge?

I would like to know if this is possible. In that case, can we have the editor program insert the source code into the db directly?

You could use the ACE editor already included in DOMjudge and indeed insert to the DB fron there (use the submit_solution function). I believe that this is not part of DOMjudge yet is that it raised workflow questions. How would the team compile and run the program to test it? Or would they submit it untested? What are your ideas about this? Cheers, Thijs

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.

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

DOMjudge 5.0.1 and Java in "chroot" (Fedora 22 64-bit)
by Marc Furon 25 Oct '15

25 Oct '15

Greetings! I am configuring DOMjudge 5.0.1 in a Fedora 22 64-bit environment. Most things seem to be working. I am trying to get Oracle Java 8u60 to run correctly in a "chroot" environment. I built the chroot directory more-or-less manually, installing Java into it (under /opt) and copying the necessary library files. I also copied /bin/bash into the chroot area along with its necessary library, and linked sh to bash. I edited the java_javac_detect script to run /opt/java/bin/java as "program". If I run a chroot command from the shell, bash starts, and I can run "/opt/java/bin/java -version". It complains about the lack of a monotonic clock but otherwise seems to run. I then tried to run the "Hello World" tests. C and C++ work fine. Java fails. I went into the execution directory and the program.err file says that it could not exec /opt/java/bin/java. Has anyone tried to get this kind of configuration running? Any ideas about how to best configure Java in this environment? Suggestions will be greatly appreciated. Marc

DOMjudge (automatic) team logins
by kjohns07 25 Oct '15

25 Oct '15

Hey everyone, I was wondering how other people handle logging teams in to domjudge during their competitions? We’ve always have volunteers go around to the team computers and manually log them in before the contest started, but I’ve always found that to be a bit tedious. We never liked the idea of giving the teams their own passwords since they could easily share them with each other. Since we control the contest environment, I found a way to use a local squid proxy to log teams in automatically, without revealing the credentials to the team. I thought I’d share this since someone else might be interested. You can read about it here: http://icpc-environment.github.io/2015/10/24/domjudge-autologin.html I don’t know if there is any interest in merging a feature like this into the main DOMjudge tree though, any thoughts? It’s a relatively small patch, but it’s such a narrow use case I don’t know if it’s worth supporting generally. -Keith Johnson US Southeast Region

Hi, I need to run MPI code, so for compiling phase it is ok I run *mpicc -lm -static -DONLINE_JUDGE -DDOMJUDGE -o $DEST "$@" * at my run file. But to run the program, I need to use *mpirun -n 16 ./compiledcode * the 16 is the number of process I have and should be configurable as the -n flag. I didn't find it on Manual.

DOM Judge Compare File
by Leandro Zanotto 04 Aug '15

Hi, I need a little help with the compare files. I am sending the files I am using so you can understand it bette. It is compiling, but when it starting running it freezes. I don’t know yet what is the problem. I think it is not reading the input. I tested it using our Queue manager (Torque) since we are using on a cluster. The compile phase is ok. Now I need to create the compare file and try to understand why it is freezing. Something maybe wrong with my code. So it prints the ordered vector and the speedup, I need to check the result with the out file and check if the speedup if greater than 1. Thank You. -- Leandro Negri Zanotto
