## EphyPermissionManager

EphyPermissionManager — Sets webpages' cookie, image and popup permissions.

## Synopsis

                EphyPermissionInfo;
    enum        EphyPermission;
    void        ephy_permission_info_free       (EphyPermissionInfo *info);

## Description

The EphyPermissionManager keeps a list of websites and their permissions. For example, the user may want a certain website to display images but block cookies and popup windows; this could correspond to three entries in the EphyPermissionManager.

Use `ephy_permission_manager_add()` to set permissions for a website, `ephy_permission_manager_remove()` to remove the permissions, and `ephy_permission_manager_test()` to test them. Note that `ephy_permission_manager_test()` may return `EPHY_PERMISSION_DEFAULT`, which means the caller might need to find the default permission some other way.

The EphyPermissionManager stores a list of site-specific permissions, but not defaults. For popups, the default permission is determined by the GConf key /apps/epiphany/web/allow_popups, which in turn determines Mozilla's dom.disable_open_during_load preference. For cookies, the GConf key /apps/epiphany/web/cookie_accept determines Mozilla's network.cookie.cookieBehavior preference. For images, the default is determined by Mozilla's network.image.imageBehavior preference.

The predefined permission types are EPT_COOKIE ("cookie"), EPT_IMAGE ("image") and EPT_POPUP ("popup"). You can also make up your own type string.

Though the word "host" is used in many function descriptions, Mozilla does not act as one would expect. Always pass a URL to any functions which need have a "host" parameter. However, the "host" in an EphyPermissionInfo is a simple DNS hostname.

## Details

### EphyPermissionInfo

    typedef struct {
    	char *host;
    	GQuark qtype;
    	EphyPermission permission;
    } EphyPermissionInfo;

Details a specific permission of a specific website.

char *`host`; | The hostname of the website to which this permission applies.
GQuark `qtype`; |
EphyPermission `permission`; | An EphyPermission (either allow or deny).

### enum EphyPermission

    typedef enum
    {
    	EPHY_PERMISSION_ALLOWED,
    	EPHY_PERMISSION_DENIED,
    	EPHY_PERMISSION_DEFAULT
    } EphyPermission;

Determines whether the website is allowed or denied access.

`EPHY_PERMISSION_ALLOWED` | The website is unconditionally allowed to perform the desired action.
`EPHY_PERMISSION_DENIED` | The website is unconditionally denied to perform the desired action.
`EPHY_PERMISSION_DEFAULT` | The user has not set a preference for this particular website; the caller should therefore fall back to default settings.

### ephy_permission_info_free ()

    void        ephy_permission_info_free       (EphyPermissionInfo *info);

Frees `info`.

`info` : | an EphyPermissionInfo
