/*
* The following section contains keys used by the GDM configuration files.
* The key/value pairs defined in the GDM configuration files are considered
* "stable" interface and should only change in ways that are backwards
* compatible. Please keep this in mind when changing GDM configuration.
*
* Developers who add new configuration options should ensure that they do the
* following:
*
* + Edit the config/gdm.conf file to include the default setting.
*
* + Specify the same default in this file as in the config/gdm.conf.in file.
*
* + Update the gdm_config_init function in daemon/gdmconfig.c to add the
* new key. Include some documentation about the new key, following the
* style of existing comments.
*
* + Add any validation to the _gdm_set_value_string, _gdm_set_value_int,
* and/or _gdm_set_value_bool functions (depending on the type of the new
* key) in gdmconfig.c, if validation is needed.
*
* + If GDM_UPDATE_CONFIG should not respond to this configuration setting,
* update the update_config function in gdmconfig.c to return FALSE for
* this key. Examples include changing the PidFile, ServAuthDir, or
* other values that GDM should not change until it is restarted. If
* this is true, the next bullet can be ignored.
*
* + If the option should cause the greeter (gdmlogin/gdmgreeter) program to
* be updated immediately, make sure to update the appropriate
* _gdm_set_value_* function in gdmconfig.c. This function calls the
* notify_displays_* function to call when this value is changed, so you
* will need to add your new config value to the list of values sending
* such notification. Supporting logic will need to be added to
* gdm_slave_handle_notify function in slave.c to process the notify.
* It should be clear to see how to do this from the existing code.
*
* + Add the key to the gdm_read_config and gdm_reread_config functions in
* gui/gdmlogin.c, gui/gdmchooser.c, and gui/greeter/greeter.c
* if the key is used by those programs. Note that all GDM slaves load
* all their configuration data between calls to gdmcomm_comm_bulk_start()
* and gdmcomm_comm_bulk_stop(). This makes sure that the slave only uses
* a single sockets connection to get all configuration data. If a new
* config value is read by a slave, make sure to load the key in this
* code section for best performance.
*
* + The gui/gdmsetup.c program should be updated to support the new option
* unless there's a good reason not to (like it is a configuration value
* that only someone who really knows what they are doing should change
* like GDM_KEY_PID_FILE).
*
* + Currently GDM treats any key in the "gui" and "greeter" categories,
* and security/PamStack as available for per-display configuration.
* If a key is appropriate for per-display configuration, and is not
* in the "gui" or "greeter" categories, then it will need to be added
* to the gdm_config_key_to_string_per_display function. It may make
* sense for some keys used by the daemon to be per-display so this
* will need to be coded (refer to GDM_KEY_PAM_STACK for an example).
*
* + Update the docs/C/gdm.xml file to include information about the new
* option. Include information about any other interfaces (such as
* ENVIRONMENT variables) that may affect the configuration option.
* Patches without documentation will not be accepted.
*
* Please do this work *before* submitting an patch. Patches that are not
* complete will not likely be accepted.
