Incorrect URL in DOMjudge Download Page
by Malcolm Corney 23 Sep '16

23 Sep '16

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

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";
