Details

class Malcontent.SessionLimits

Malcontent.SessionLimits is an opaque, immutable structure which contains a snapshot of the session limits settings for a user at a given time. This includes whether session limits are being enforced, and the limit policy — for example, the times of day when a user is allowed to use the computer.

Typically, session limits settings can only be changed by the administrator, and are read-only for non-administrative users. The precise policy is set using polkit.

New in version 0.5.0.

classmethod deserialize(variant, user_id)

Parameters:

• variant (GLib.Variant) – a serialized session limits variant

• user_id (int) – the ID of the user the session limits relate to

Raises:

GLib.Error

Returns:

deserialized session limits

Return type:

Malcontent.SessionLimits

Deserialize a set of session limits previously serialized with Malcontent.SessionLimits.serialize(). This function guarantees to be able to deserialize any serialized form from this version or older versions of libmalcontent.

If deserialization fails, Malcontent.ManagerError.INVALID_DATA will be returned.

New in version 0.7.0.

check_time_remaining(now_usecs)

Parameters:

now_usecs (int) – current time as microseconds since the Unix epoch (UTC), typically queried using GLib.get_real_time()

Returns:

True if the user this self corresponds to is allowed to be in an active session at the given time; False otherwise

time_remaining_secs_out:

return location for the number of seconds remaining before the user’s session has to end, if limits are in force

time_limit_enabled_out:

return location for whether time limits are enabled for this user

Return type:

(bool, time_remaining_secs_out: int, time_limit_enabled_out: bool)

Check whether the user has time remaining in which they are allowed to use the computer, assuming that now_usecs is the current time, and applying the session limit policy from self to it.

This will return whether the user is allowed to use the computer now; further information about the policy and remaining time is provided in time_remaining_secs_out and time_limit_enabled_out.

New in version 0.5.0.

get_user_id()

Returns:

user ID of the relevant user, or (uid_t) -1 if unknown

Return type:

int

Get the user ID of the user this Malcontent.SessionLimits is for.

New in version 0.5.0.

is_enabled()

Returns:

True if the session limits object contains at least one restrictive session limit, False if there are no limits in place

Return type:

bool

Check whether any session limits are enabled and are going to impose at least one restriction on the user. This gives a high level view of whether session limit parental controls are ‘enabled’ for the given user.

This function is equivalent to the value returned by the time_limit_enabled_out argument of Malcontent.SessionLimits.check_time_remaining().

New in version 0.7.0.

ref()

Returns:

the same pointer as self

Return type:

Malcontent.SessionLimits

Increment the reference count of self, and return the same pointer to it.

New in version 0.5.0.

serialize()

Returns:

a new, floating GLib.Variant containing the session limits

Return type:

GLib.Variant

Build a GLib.Variant which contains the session limits from self, in an opaque variant format. This format may change in future, but Malcontent.SessionLimits.deserialize() is guaranteed to always be able to load any variant produced by the current or any previous version of Malcontent.SessionLimits.serialize().

New in version 0.7.0.

unref()

Decrement the reference count of self. If the reference count reaches zero, free the self and all its resources.

New in version 0.5.0.
