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"!

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

Up to this stage, I don’t know it is or not enable

What I'm looking for is actually the line below "webserver group" that says:

  * use Linux cgroups...: yes/no

But when I logged in to your machine, /root/domjudge-5.1.1/config.log shows that cgroups are disabled. You have the package installed, but have not edited /etc/default/grub, so the kernel doesn't support cgroups yet.

As a side note, you should not install DOMjudge as root user. Instead create a separate user to install it as: DOMjudge will use 'sudo' to obtain root privileges only when needed.

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

Not yet it is not listed in the document 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.

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.

P.S. If you have further questions, please return to using the mailinglist.
