1/** @file
2 * Settings File Manipulation API.
3 *
4 * Two classes, MainConfigFile and MachineConfigFile, represent the VirtualBox.xml and
5 * machine XML files. They share a common ancestor class, ConfigFileBase, which shares
6 * functionality such as talking to the XML back-end classes and settings version management.
7 *
8 * The code can read all VirtualBox settings files version 1.3 and higher. That version was
9 * written by VirtualBox 2.0. It can write settings version 1.7 (used by VirtualBox 2.2 and
10 * 3.0) and 1.9 (used by VirtualBox 3.1).
11 *
12 * Rules for introducing new settings: If an element or attribute is introduced that was not
13 * present before VirtualBox 3.1, then settings version checks need to be introduced. The
14 * settings version for VirtualBox 3.1 is 1.9; see the SettingsVersion enumeration in
15 * src/VBox/Main/idl/VirtualBox.xidl for details about which version was used when.
16 *
17 * The settings versions checks are necessary because VirtualBox 3.1 no longer automatically
18 * converts XML settings files but only if necessary, that is, if settings are present that
19 * the old format does not support. If we write an element or attribute to a settings file
20 * of an older version, then an old VirtualBox (before 3.1) will attempt to validate it
21 * with XML schema, and that will certainly fail.
22 *
23 * So, to introduce a new setting:
24 *
25 * 1) Make sure the constructor of corresponding settings structure has a proper default.
26 *
27 * 2) In the settings reader method, try to read the setting; if it's there, great, if not,
28 * the default value will have been set by the constructor.
29 *
30 * 3) In the settings writer method, write the setting _only_ if the current settings
31 * version (stored in m->sv) is high enough. That is, for VirtualBox 3.1, write it
32 * only if (m->sv >= SettingsVersion_v1_9).
33 *
34 * 4) In MachineConfigFile::bumpSettingsVersionIfNeeded(), check if the new setting has
35 * a non-default value (i.e. that differs from the constructor). If so, bump the
36 * settings version to the current version so the settings writer (3) can write out
37 * the non-default value properly.
38 *
39 * So far a corresponding method for MainConfigFile has not been necessary since there
40 * have been no incompatible changes yet.
