{{Stub}}  == Setting up working environment == === Obtaining the source code === The sources of OpenVZ components are tracked by Git SCM and placed on * [[OpenVZ infrastructure|repositoriesKernel patches]].You either could download packed sources or use git tool itself. For example to clone vzctl one need to type  git clone git://git.openvz.org/vzctl.git  === Compiling the source code === {{FIXME|describe how to compile OpenVZ components}}  == Changing the source code == === Kernel === When you change the source code keep in mind - we prefer tabs and indentationsto be 8 characters width. Consider reading * [[https://www.kernel.org/doc/Documentation/CodingStyle Linux kernel coding style]. Other "rules" could be learned from the source code - just make your codeto look similar. === Userspace === {{FIXME|describe code style}}  == Producing a patch == === Kernel === There are at least two ways to make it right.  1) git format-patch You might need to read documentation on Git SCM how to prepare patchfor mail submission. Take a look on http://book.git-scm.com/ and/orhttp://git-scm.com/documentation for details. It should not be hardat all.  2) Use "diff -up" Use <code>diff -up</code> or <code>diff -uprN</code> to create patches.  === Userspace === {{FIXME|describe preparing patch}}  == Checking patches for errors == === Kernel === Basic style error checking is provided by scripts/checkpatch.pl scriptfrom linux kernel source tree. You might have headers or complete sourcesof linux kernel at /usr/src/. Run  checkpatch.pl my_patch.patch (consider --no-tree option for headers-only) It will produce detailed report on style problems in your patch.Make sure to fix all _errors_(some warnings may be ignored).  === Userspace === Several of our components contains tests. To check whether your patches don't harm anything run:  make test It will launch tests. Check for error messages produced by it.Beside to functional and unit tests it would be good to check new code with [[Static code analysis|staticanalysis tools]]. == Sending patches == === Kernel === Patches related to kernel should be sent to development mailing list devel@openvz.orgwhich is located at https://openvz.org/mailman/listinfo/devel. Pay attention that mailsfrom emails not subscribed to list must pass moderation (i.e. not so fast). Please make sure the email client you're using doesn't screw your patch(line wrapping and so on). === Userspace === Patches related to userspace tools should be submitted to code review system (FIXME).
