They share a common ancestor class, ConfigFileBase, which shares * functionality such as talking to the XML back-end classes and settings version management. * * The code can read all VirtualBox settings files version 1.3 and higher. That version was * written by VirtualBox 2.0. It can write settings version 1.7 (used by VirtualBox 2.2 and * 3.0) and 1.9 (used by VirtualBox 3.1) and newer ones obviously. * * The settings versions enum is defined in src/VBox/Main/idl/VirtualBox.xidl. To introduce * a new settings version (should be necessary at most once per VirtualBox major release, * if at all), add a new SettingsVersion value to that enum and grep for the previously * highest value to see which code in here needs adjusting. * * Certainly ConfigFileBase::ConfigFileBase() will. Change VBOX_XML_VERSION below as well. * VBOX_XML_VERSION does not have to be changed if the settings for a default VM do not * touch newly introduced attributes or tags. It has the benefit that older VirtualBox * versions do not trigger their "newer" code path. * * Once a new settings version has been added, these are the rules for introducing a new * setting: If an XML element or attribute or value is introduced that was not present in * previous versions, then settings version checks need to be introduced. See the * SettingsVersion enumeration in src/VBox/Main/idl/VirtualBox.xidl for details about which * version was used when. * * The settings versions checks are necessary because since version 3.1, VirtualBox no longer * automatically converts XML settings files but only if necessary, that is, if settings are * present that the old format does not support. If we write an element or attribute to a * settings file of an older version, then an old VirtualBox (before 3.1) will attempt to * validate it with XML schema, and that will certainly fail. * * So, to introduce a new setting: * * 1) Make sure the constructor of corresponding settings structure has a proper default. * * 2) In the settings reader method, try to read the setting; if it's there, great, if not, * the default value will have been set by the constructor. The rule is to be tolerant * here. * * 3) In MachineConfigFile::bumpSettingsVersionIfNeeded(), check if the new setting has * a non-default value (i.e. that differs from the constructor). If so, bump the * settings version to the current version so the settings writer (4) can write out * the non-default value properly. * * So far a corresponding method for MainConfigFile has not been necessary since there * have been no incompatible changes yet. * * 4) In the settings writer method, write the setting _only_ if the current settings * version (stored in m->sv) is high enough. That is, for VirtualBox 4.0, write it * only if (m->sv >= SettingsVersion_v1_11). * * 5) You _must_ update xml/VirtalBox-settings.xsd to contain the new tags and attributes. * Check that settings file from before and after your change are validating properly. * Use "kmk testvalidsettings", it should not find any files which don't validate. */ /* * Copyright (C) 2007-2016 Oracle Corporation * * This file is part of VirtualBox Open Source Edition (OSE), as * available from http://www.virtualbox.org.
