EphyPermissionManagerEphyPermissionManager — Sets webpages' cookie, image and popup permissions. |
EphyPermissionInfo; enum EphyPermission; void ephy_permission_info_free (EphyPermissionInfo *info); void ephy_permission_manager_add (EphyPermissionManager *manager, const char *host, const char *type, EphyPermission permission); void ephy_permission_manager_remove (EphyPermissionManager *manager, const char *host, const char *type); void ephy_permission_manager_clear (EphyPermissionManager *manager); EphyPermission ephy_permission_manager_test (EphyPermissionManager *manager, const char *host, const char *type); GList* ephy_permission_manager_list (EphyPermissionManager *manager, const char *type);
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.
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). |
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. |
void ephy_permission_info_free (EphyPermissionInfo *info);
Frees info
.

an EphyPermissionInfo |
void ephy_permission_manager_add (EphyPermissionManager *manager, const char *host, const char *type, EphyPermission permission);
Adds the specified permission to the permissions database.
manager : |
the EphyPermissionManager |
host : |
a website URL |
type : |
a string to identify the type of the permission |
permission : |
either EPHY_PERMISSION_ALLOWED or EPHY_PERMISSION_DENIED
|
void ephy_permission_manager_remove (EphyPermissionManager *manager, const char *host, const char *type);
Removes the specified permission from the permissions database. This implies
that the browser should use defaults when next visiting the specified
host
's web pages.

host : |
a website URL |
type : |
a string to identify the type of the permission |
void ephy_permission_manager_clear (EphyPermissionManager *manager);
Clears the permissions database. This cannot be undone.
manager : |
the EphyPermissionManager |
EphyPermission ephy_permission_manager_test (EphyPermissionManager *manager, const char *host, const char *type);
Retrieves an EphyPermissionType from the permissions database. If there is
no entry for this type
and host
, it will return EPHY_PERMISSION_DEFAULT
.
In that case, the caller may need to determine the appropriate default
behavior.
manager : |

host : |
a website URL |
type : |
a string to identify the type of the permission |
Returns : | the permission of type EphyPermission |
GList* ephy_permission_manager_list (EphyPermissionManager *manager, const char *type);
Lists all permission entries of type type
in the permissions database, each
as its own EphyPermissionInfo. These entries must be freed using
ephy_permission_info_free()
.
manager : |

Returns : | the list of permission database entries |
