I recommend not to change it like that: then if you change the configured global memory limit, it will not affect Java submissions. Also, if you now reduce the memory limit below 3 GB, then java submissions will automatically crash because the JVM is trying to allocate more memory than is allowed by DOMjudge. NOTE: DOMjudge imposes the memory limit onto the whole Java VM, that's why this this whole MEMRESERVED variable is needed in the first place.

Hi Huynh Anh Dung I don't think affiliations are included in the self-registration capabilities of the current DOMjudge release. We patched our own local version to do them. I attached our modified version of the file domserver/lib/www/auth.php. It requires users to select from the existing list of affiliations known to the site, or NOT KNOWN otherwise. It comes with no guarantees, but it work for us. There's also a bit of an issue with self-registration: it works only if you get to the login screen by clicking the 'login' button, but not when you get to the same page by other routes, e.g. you enter an url like <servername>/team.index.php. A hack to fix that bug: in domserver/www/team/index.php, add a line after line 29 so that lines 29 to 30 read: if ( @$_POST['cmd']=='login' ) do_login(); if ( @$_POST['cmd']=='register' ) do_register(); // ** ADD THIS LINE ** Hope that helps Richard On 08/05/16 08:58, Huynh Anh Dung wrote:

Hi Jaap, Can you look at 2 lines : # exec java -client -Xss8m -Xmx${MEMLIMITJAVA}k -DONLINE_JUDGE=1 -DDOMJUDGE=1 '$MAINCLASS' exec java -client -Xmx3g -DONLINE_JUDGE=1 -DDOMJUDGE=1 '$MAINCLASS' before you change and successfully run, I already change. I recommend not to change it like that: then if you change the configured global memory limit, it will not affect Java submissions. Also, if you now reduce the memory limit below 3 GB, then java submissions will automatically crash because the JVM is trying to allocate more memory than is allowed by DOMjudge. NOTE: DOMjudge imposes the memory limit onto the whole Java VM, that's why this this whole MEMRESERVED variable is needed in the first place.
Jaap
P.S. If you have further questions, please return to using the mailinglist.

Hi Richard, 2 issues : 1- I have not seen auth.php in www/auth I send you images 1,2 to look at these image files. 2- Image file 3, I insert this line if ( @$_POST['cmd']=='login' ) do_login(); if ( @$_POST['cmd']=='register' ) do_register(); between line 29 and 30 but this line is empty line. Please look at these images files and give me suggestion. Best regards Lec.

Hi Huỳnh Anh Dũng You're probably running a slightly different version of domjudge from me. And it looks like the layout of my email might have broken in your email client. You should look for the line: if ( @$_POST['cmd']=='login' ) do_login(); in www/team/index.php, somewhere near line 29. If you can't find that line/**don't touch the code/. It must have changed too much. If you do find that line, add the following line /after/ it: if ( @$_POST['cmd']=='register' ) do_register(); // ** ADD THIS LINE ** It would pay to look before pasting to make sure there isn't a call to do_register() somewhere already in your version of the code. However, maybe an even better approach is for you to do absolutely nothing until/unless you hit the bug that this patch is meant to fix. The bug only shows if you navigate directly to the team index page in some way (e.g. with a saved link, or a link from somewhere else). If a user goes directly to your site base url and clicks login, everything should work anyway. We have a saying "If it isn't broken, don't fix it"! Richard On 08/05/16 12:17, Huynh Anh Dung wrote:

I recommend not to change it like that: then if you change the configured global memory limit, it will not affect Java submissions. Also, if you now reduce the memory limit below 3 GB, then java submissions will automatically crash because the JVM is trying to allocate more memory than is allowed by DOMjudge. NOTE: DOMjudge imposes the memory limit onto the whole Java VM, that's why this this whole MEMRESERVED variable is needed in the first place. Jaap P.S.

Hi Tobias OK, done that. I should mention though that I'm not completely happy with the bug fix that I mentioned below. The problem is that the same login form is presented from three different places: login.php, team/index.php and jury/index.php. Self-registration works only from the first of those. My hack fix is to replicate the call to do_register that's within public/login.php within team/init.php but that leaves the anomalous situation that you also get offered a self-registration option if you navigate into jury/index. It doesn't work (and I doubt we want it to!) but I don't think it should even be presented as an option. I haven't fixed that. We have one other local patch that may or may not interest you. [I haven't pushed it to the repository.] On one of our servers we have a regular series of contests with old contests left running. We get lots of teams self-registering for just one contest, so soon get a scoreboard that's mostly full of non-participating teams. The patch is to limit the scoreboard display to just those teams that have made at least one submission to the contest that's being displayed. Of course, for a major contest what you have is correct - you want to show all teams, including the ones that haven't submitted yet. To support both modes of operation you would need to have a configuration parameter to turn on and off display of all teams. However, I know that you're trying to limit the number of configuration parameters so you might not wish to go down this path. The patch is of course simple: within the getTeams() function in lib/www/scoreboard.php, just add to the query the line INNER JOIN submission USING (cid, teamid) I did consider doing this with a filter or checkbox on the scoreboard but that didn't seem right. It's a fundamental difference in the scoreboard role: with lots of users, only some involved in this contest, it never makes sense to show them all. Richard On 08/05/16 18:16, Tobias Werth wrote:

Hi Huỳnh Anh Dũng, You can simply delete contests from the jury/admin webinterface. Unless you have many contests, this should not be that much work; it will also delete all submissions, clarifications, and judging data associated to that contest. To delete many users it may be more convenient to use phpMyAdmin or the MySQL commandline interface directly. You should be able to quickly delete all users (and teams, I suppose) but beware that you don't delete the admin and judgehost users. Jaap On 13-06-16 02:27, Huynh Anh Dung wrote:

HI,
Did you install or copy runguard to the judgehost installation (under judgehost/bin)? This step is not explicitly listed in the documentation. Yes, runguard is there. best

Hi, I do follow exact with the help file and I do up to: -Install the necessary packages: # apt-get install libcgroup-dev (or # yum install libcgroup-devel on RedHat) - Edit grub config to add memory cgroup and swap accounting to the boot options. Edit /etc/default/grub and change the default commandline to GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1". Then run update-grub and reboot. -Compile DOMjudge with cgroup support. Re-run ./configure and look for cgroup in the output.
And did the configure output say that cgroups were enabled?
How to rebuild : Then rebuild the runguard with make build. I only make all after re-run ./configure
Did you install or copy runguard to the judgehost installation (under judgehost/bin)? This step is not explicitly listed in the documentation. Jaap
Upto that point, then I run ./judgedaemon Then I said no cgroup Best

When you (re)ran configure did it say that cgroups were enabled?
Did you recompile and reinstall runguard (or the whole judgehost installation)?

Hi Jaap, Can you look at 2 lines : # exec java -client -Xss8m -Xmx${MEMLIMITJAVA}k -DONLINE_JUDGE=1 -DDOMJUDGE=1 '$MAINCLASS' exec java -client -Xmx3g -DONLINE_JUDGE=1 -DDOMJUDGE=1 '$MAINCLASS' before you change and successfully run, I already change.
I recommend not to change it like that: then if you change the configured global memory limit, it will not affect Java submissions. Also, if you now reduce the memory limit below 3 GB, then java submissions will automatically crash because the JVM is trying to allocate more memory than is allowed by DOMjudge. NOTE: DOMjudge imposes the memory limit onto the whole Java VM, that's why this this whole MEMRESERVED variable is needed in the first place.

HI, I don’t understand these lines below: You have now configured the system to use cgroups, but you need to create the actual cgroups that DOMjudge will use. For that, you can use the script under misc-tools/create_cgroups. Edit the script to match your situation first. This script needs to be re-run after each boot (e.g., add it to the judgedaemon init script). I did run misc-tools/create_cgroups but it did not help. Best, Lec.
