Online Judge plugin for Moodle 2.7-4.2.

moodle-local_onlinejudge's Issues

extension_loaded('pcntl') broken on RHEL 6

This issue is reported by @trampgeek . His report:

There's a check in your judge install script:

if (!extension_loaded('pcntl') || !extension_loaded('posix')) {
cli_error('PHP pcntl and posix extension must be installed!');
}

On RHEL6, 'pcntl' is compiled into PHP and extension_loaded('pcntl') returns FALSE [which I admit seems odd but I just checked] even though all its function are in fact available. So I finished up just commenting that line out. You may be able to find a better work around than that :)

Some Suggestions

Hello, I am a student of University of Sao Paulo.

We used Moodle Online Judge Plugin in some tasks of Object-Oriented Programming classes.

To improve the activities I did a small change in your code. I added the following options for activities:
-Insert a preamble in a code;
-Insert a postamble in a code;

With this options the teacher can add some pieces of code in all tasks sent to the activity.
In University of Sao Paulo, we used this options to establish the main function for all students. So, we can evaluate if the student used correct programming techniques like heritage and polymorphism in Java. It isn't possible with only output comparision.

I have released these changes in a google code repository http://code.google.com/p/moodle-online-judge-changes/
However, I think it would be interesting if these changes were made ​​by you, who built the entire project. So I want to make this suggestion to you.

Another suggestion is a plug in to use the online judge as a question type of a quiz in moodle. That would be interesting why moodle add all activities to grade board, and several times we use your plugin for a non-evaluated activity and in actitivities with more than one exercise.

It is a great project, thanks.

judge后台进程停摆报警

在local插件的cron中检查judge后台进程多久没判题了。如果过久，就发email给管理员。发给谁在设置中设定。选人的界面参考网站设置中开课请求发给谁的那个设置

lib.php中增加onlinejudge_cron()函数，它完成相应功能。 浏览器访问admin/cron.php，或者命令行php admin/cli/cron.php可以触发此函数

文件上传问题

  我的平台如果安装moodle 2.1，在线评测的评测用例文件不能加载

当我改成moodle2.2时这个问题得到解决，但普通的作业文件又不能正常上传，.c文件，.txt文件可以，
但其它类型的如word，excel，ppt，压缩文件等都不能上传，点击上传的时候却弹出来下载的对话框。
现在被这个问题困惑，装2.1的测试用例文件上传不了，装2.2的学生作业又提交不了。

系统更新数据备份问题

老系统中的课程数据备份后在更新后的系统中不能正确还原，点击还原后的连接找不到数据，不知道应该注意什么问题才能保证正确的还原，直接把原来在moodledata中的数据拷贝下来，更新后再拷贝进来可以吗？

为judge_base增加is_available()方法

用来判断各个judge是否可用。可以用的，才会从get_language()返回。

sandbox只有在Linux下且judge/sandbox/sand/sand文件可执行时可用。

ideone只有在php soap扩建已安装时可用。

自动重新编译

如何让学生的代码重新提交 后能立即加入编译运行队列？

What functions is restricted in C language(local) onlinejudge?

I know gets,fgets,system(pause).But what is else restriced function ?can you list all of them?

Judging fails with "Restricted Functions"

There seems to be some odd behaviour when using judged and sandbox combination.

After trying to judge a simple hello world example (hello.c) judging states "Restricted Functions". The file hello.c has the following lines:

# include

int
main(int argc, const char *argv[])
{
printf("hello world\n");
return 0;
}

When running the judged with:
$ sudo -u www-data php judged.php -v -n
it outputs the following lines when doing an evalution:

== TASK: 41 == Judging... Successfully judged: 8

System is running Ubuntu 10.04, Apache2 and PHP 5.3.2. Online judge version is cloned from the 063b303 commit.

Any tips how should I progress to gain more information?

Thanks in advance!

在线评测的运行时错误是怎么回事？

我用的是ideone在线评测，有的题目会出现莫名其妙的运行时错误，不知道是怎么回事。

答案：直接在ideone平台上查看了相关信息，只有一个运行状态re，仔细看了学生的程序，原来int main(void)主程序没有return 0 也会使ideone呈现运行时错误状态，然而却没有影响正确的运行结果。
丢掉return 0的main程序，直接用gcc或g++编译运行，没有错误。

使用PHP-FineDiff，显示学生输出和标准答案的diff状态

Regarding Online Judge Usage

Thanks for your previous reply.
I logged in as a student and uploaded a sample code in c in Moodle .
But i did not see anything like onlinejudge assignment .
Can u please send the steps on how to use online judge plugin .
Also which moodle version will u recommend to use for Online judge plugin.
I am in spot of bother.
Please help me out.
I really need to work on this plugin!!

Setting proxy for plugin

my connection allows only port 80 and added to that how can I set the pxoxy for the judge because it is not able to send the code to ideom.com because of proxy and I am using the plugin in moodle 2.0 onlinejudge2, can anyone advise me on how I can set the proxy for the plugin or moodle as a whole?

在设置ideone用户和密码时做验证

clients / mod / assignment / type / onlinejudge / assignment.class.php 中的 form_validation()函数验证教师为作业设置的各种参数是否合法。现在这里对ideone的用户名和密码只校验是否存在，不校验是否有效。

需要在这里调用ideone api中的testFunction()方法，验证用户名和密码是否正确。如果不正确，通过设置errors[]数组提示用户修正。

有了此功能，就不需要用户输入两次密码了

java submissions always exceed memory limit

When I add a java assignment as a teacher and submit it as a student, I always get "Memory-Limit Exceed", even with the most basic "hello world" program. When I submit the same program to ideone directly it reports a memory usage of around 240MB. Although when adding the assignment I can only choose the maximum memory usage to be between 1MB and 64MB. Is there any way I can fix this, or am I doing anything wrong? This seems to be an issue with java programs. I made another assignment and can submit a c-program for example and get it accepted without any problems.

I hope this is the right place for such a question, I came here through the "Bug reports, feature requests, help wanted and other issues" link in readme.md. Any help is highly appreciated =)

        'c' => 'gcc -D_MOODLE_ONLINE_JUDGE_ -Wall -static -o %DEST% %SOURCE% -lm',
        'c_warn2err' => 'gcc -D_MOODLE_ONLINE_JUDGE_ -Wall -Werror -static -o %DEST% %SOURCE% -lm',
        'cpp' => 'g++ -D_MOODLE_ONLINE_JUDGE_ -Wall -static -o %DEST% %SOURCE% -lm',
        'cpp_warn2err' => 'g++ -D_MOODLE_ONLINE_JUDGE_ -Wall -Werror -static -o %DEST% %SOURCE% -lm'

其中-lm参数挪到-static后面比较好。要做的就是这个

Sandbox refuses to make

After compling the local sandbox environment in an Ubuntu 11.04 (x86) in a virtual machine, I find that when make tries to run the tests libsandbox just keeps throwing status 8 (Internal error). Why could it happen? If more information about the system is needed just ask for it.
Thank you!

why does it show Accept but no score in all judge by one time?

/usr/bin/ld: cannot open output file a.out: No such file or directory
collect2: ld 返回 1
the result of all judge show abnormal,why?
the same program show diffrent result

Unable to use online judge plugin

I have properly installed this Online-Judge plugin in Ubuntu 12.04. I am using moodle 2.3+. I am unable to find out :-

1). Where can a student upload his c/c++ code .
2) .From where will the sandbox tool run and evaluates this code.

I have installed sandbox using make command. But i am not not able to run sandbox. I have read all readme files but unable to get information.

I have referred this site for installing Online Judge:-

https://github.com/hit-moodle/moodle-local_onlinejudge

Please Help me out !!!!

在线评测测试用例来自于文件不能添加文件

管理测试用例页面打开之后，只有第一个测试用例里的输入文件出现添加按钮，但一直处于loading状态，输出文件和其它测试用例的输入/输出文件都有一个等待的标志在转动，点击唯一的一个添加按钮没有任何反应，网页的左下方显示网页上有错误，不知道是哪里出了问题，请各位帮助分析一下。
直接在输入/输出窗口中输入用例没有问题。今天布置的第一道用文件的在线评测题，才发现这个问题。

online judge 作业移动不了！

布置的onlinejudge作业，虽然显示有四向箭头（提示“移动”），但点击没有反应是什么原因？我是在win7的ie浏览器下使用的。其它按钮都起作用。
