3 * Settings File Manipulation API.
4 *
5 * Two classes, MainConfigFile and MachineConfigFile, represent the VirtualBox.xml and
6 * machine XML files. They share a common ancestor class, ConfigFileBase, which shares
7 * functionality such as talking to the XML back-end classes and settings version management.
8 *
9 * The code can read all VirtualBox settings files version 1.3 and higher. That version was
10 * written by VirtualBox 2.0. It can write settings version 1.7 (used by VirtualBox 2.2 and
11 * 3.0) and 1.9 (used by VirtualBox 3.1) and newer ones obviously.
12 *
13 * The settings versions enum is defined in src/VBox/Main/idl/VirtualBox.xidl. To introduce
14 * a new settings version (should be necessary at most once per VirtualBox major release,
15 * if at all), add a new SettingsVersion value to that enum and grep for the previously
16 * highest value to see which code in here needs adjusting.
17 *
18 * Certainly ConfigFileBase::ConfigFileBase() will. Change VBOX_XML_VERSION below as well.
19 *
20 * Once a new settings version has been added, these are the rules for introducing a new
21 * setting: If an XML element or attribute or value is introduced that was not present in
22 * previous versions, then settings version checks need to be introduced. See the
23 * SettingsVersion enumeration in src/VBox/Main/idl/VirtualBox.xidl for details about which
24 * version was used when.
25 *
26 * The settings versions checks are necessary because since version 3.1, VirtualBox no longer
27 * automatically converts XML settings files but only if necessary, that is, if settings are
28 * present that the old format does not support. If we write an element or attribute to a
29 * settings file of an older version, then an old VirtualBox (before 3.1) will attempt to
30 * validate it with XML schema, and that will certainly fail.
31 *
32 * So, to introduce a new setting:
33 *
34 * 1) Make sure the constructor of corresponding settings structure has a proper default.
35 *
36 * 2) In the settings reader method, try to read the setting; if it's there, great, if not,
37 * the default value will have been set by the constructor. The rule is to be tolerant
38 * here.
39 *
40 * 3) In MachineConfigFile::bumpSettingsVersionIfNeeded(), check if the new setting has
41 * a non-default value (i.e. that differs from the constructor). If so, bump the
42 * settings version to the current version so the settings writer (4) can write out
43 * the non-default value properly.
44 *
45 * So far a corresponding method for MainConfigFile has not been necessary since there
46 * have been no incompatible changes yet.
47 *
48 * 4) In the settings writer method, write the setting _only_ if the current settings
49 * version (stored in m->sv) is high enough. That is, for VirtualBox 4.0, write it
50 * only if (m->sv >= SettingsVersion_v1_11).
