-/**
- * This thread maintains an internal state associating clients and triggers.
- *
- * In order to speed-up and simplify queries, hash tables providing the
- * following associations are maintained:
- *
- * - client_socket_ht: associate a client's socket (fd) to its
- * "struct notification_client".
- * This hash table owns the "struct notification_client" which must
- * thus be disposed-of on removal from the hash table.
- *
- * - client_id_ht: associate a client's id to its "struct notification_client"
- * This hash table holds a _weak_ reference to the
- * "struct notification_client".
- *
- * - channel_triggers_ht:
- * associates a channel key to a list of
- * struct lttng_trigger_list_nodes. The triggers in this list are
- * those that have conditions that apply to a particular channel.
- * A channel entry is only created when a channel is added; the
- * list of triggers applying to such a channel is built at that
- * moment.
- * This hash table owns the list, but not the triggers themselves.
- *
- * - session_triggers_ht:
- * associates a session name to a list of
- * struct lttng_trigger_list_nodes. The triggers in this list are
- * those that have conditions that apply to a particular session.
- * A session entry is only created when a session is created; the
- * list of triggers applying to this new session is built at that
- * moment. This happens at the time of creation of a session_info.
- * Likewise, the list is destroyed at the time of the session_info's
- * destruction.
- *
- * - channel_state_ht:
- * associates a pair (channel key, channel domain) to its last
- * sampled state received from the consumer daemon
- * (struct channel_state).
- * This previous sample is kept to implement edge-triggered
- * conditions as we need to detect the state transitions.
- * This hash table owns the channel state.
- *
- * - notification_trigger_clients_ht:
- * associates notification-emitting triggers to clients
- * (struct notification_client_list) subscribed to those
- * conditions.
- * The condition's hash and match functions are used directly since
- * all triggers in this hash table have the "notify" action.
- * This hash table holds no ownership.
- *
- * - channels_ht:
- * associates a channel_key to a struct channel_info. The hash table
- * holds the ownership of the struct channel_info.
- *
- * - sessions_ht:
- * associates a session_name (hash) to a struct session_info. The
- * hash table holds no ownership of the struct session_info;
- * the session_info structure is owned by the session's various
- * channels through their struct channel_info (ref-counting is used).
- *
- * - triggers_ht:
- * associates a trigger to a struct lttng_trigger_ht_element.
- * The hash table holds the ownership of the
- * lttng_trigger_ht_elements along with the triggers themselves.
- * - triggers_by_name_uid_ht:
- * associates a trigger (name, uid) tuple to
- * a struct lttng_trigger_ht_element.
- * The hash table does not hold any ownership and is used strictly
- * for lookup on registration.
- * - tracer_event_sources_list:
- * A list of tracer event source (read side fd) of type
-* struct notification_event_tracer_event_source_element.
-*
- *
- * The thread reacts to the following internal events:
- * 1) creation of a tracing channel,
- * 2) destruction of a tracing channel,
- * 3) registration of a trigger,
- * 4) unregistration of a trigger,
- * 5) reception of a channel monitor sample from the consumer daemon,
- * 6) Session rotation ongoing,
- * 7) Session rotation completed,
- * 8) registration of a tracer event source,
- * 9) unregistration of a tracer event source,
- *
- * Events specific to notification-emitting triggers:
- * 9) connection of a notification client,
- * 10) disconnection of a notification client,
- * 11) subscription of a client to a conditions' notifications,
- * 12) unsubscription of a client from a conditions' notifications,
- *
- *
- * 1) Creation of a tracing channel
- * - notification_trigger_clients_ht is traversed to identify
- * triggers which apply to this new channel,
- * - triggers identified are added to the channel_triggers_ht.
- * - add channel to channels_ht
- * - if it is the first channel of a session, a session_info is created and
- * added to the sessions_ht. A list of the triggers associated with that
- * session is built, and it is added to session_triggers_ht.
- *
- * 2) Destruction of a tracing channel
- * - remove entry from channel_triggers_ht, releasing the list wrapper and
- * elements,
- * - remove entry from the channel_state_ht.
- * - remove channel from channels_ht
- * - if it was the last known channel of a session, the session_info
- * structure is torndown, which in return destroys the list of triggers
- * applying to that session.
- *
- * 3) Registration of a trigger
- * - if the trigger's action is of type "notify",
- * - traverse the list of conditions of every client to build a list of
- * clients which have to be notified when this trigger's condition is met,
- * - add list of clients (even if it is empty) to the
- * notification_trigger_clients_ht,
- * - add trigger to channel_triggers_ht (if applicable),
- * - add trigger to session_triggers_ht (if applicable),
- * - add trigger to triggers_by_name_uid_ht
- * - add trigger to triggers_ht
- * - evaluate the trigger's condition right away to react if that condition
- * is true from the beginning.
- *
- * 4) Unregistration of a trigger
- * - if the trigger's action is of type "notify",
- * - remove the trigger from the notification_trigger_clients_ht,
- * - remove trigger from channel_triggers_ht (if applicable),
- * - remove trigger from session_triggers_ht (if applicable),
- * - remove trigger from triggers_by_name_uid_ht
- * - remove trigger from triggers_ht
- *
- * 5) Reception of a channel monitor sample from the consumer daemon
- * - evaluate the conditions associated with the triggers found in
- * the channel_triggers_ht,
- * - if a condition evaluates to "true" and the condition is of type
- * "notify", query the notification_trigger_clients_ht and send
- * a notification to the clients.
- *
- * 6) Session rotation ongoing
- *
- * 7) Session rotation completed
- *
- * 8) Registration of a tracer event source
- * - Add the tracer event source of the application to
- * tracer_event_sources_list,
- * - Add the trace event source to the pollset.
- *
- * 8) Unregistration of a tracer event source
- * - Remove the tracer event source of the application from
- * tracer_event_sources_list,
- * - Remove the trace event source from the pollset.
- *
- * 10) Connection of a client
- * - add client socket to the client_socket_ht,
- * - add client socket to the client_id_ht.
- *
- * 11) Disconnection of a client
- * - remove client socket from the client_id_ht,
- * - remove client socket from the client_socket_ht,
- * - traverse all conditions to which the client is subscribed and remove
- * the client from the notification_trigger_clients_ht.
- *
- * 12) Subscription of a client to a condition's notifications
- * - Add the condition to the client's list of subscribed conditions,
- * - Look-up notification_trigger_clients_ht and add the client to
- * list of clients.
- * - Evaluate the condition for the client that subscribed if the trigger
- * was already registered.
- *
- * 13) Unsubscription of a client to a condition's notifications
- * - Remove the condition from the client's list of subscribed conditions,
- * - Look-up notification_trigger_clients_ht and remove the client
- * from the list of clients.

+ * This hash table owns the "struct notification_client" which must
+ * thus be disposed-of on removal from the hash table.
+ *
+ * - client_id_ht: associate a client's id to its "struct notification_client"
+ * This hash table holds a _weak_ reference to the
+ * "struct notification_client".
+ *
+ * - channel_triggers_ht:
+ * associates a channel key to a list of
+ * struct lttng_trigger_list_nodes. The triggers in this list are
+ * those that have conditions that apply to a particular channel.
+ * A channel entry is only created when a channel is added; the
+ * list of triggers applying to such a channel is built at that
+ * moment.
+ * This hash table owns the list, but not the triggers themselves.
+ *
+ * - session_triggers_ht:
+ * associates a session name to a list of
+ * struct lttng_trigger_list_nodes. The triggers in this list are
+ * those that have conditions that apply to a particular session.
+ * A session entry is only created when a session is created; the
+ * list of triggers applying to this new session is built at that
+ * moment. This happens at the time of creation of a session_info.
+ * Likewise, the list is destroyed at the time of the session_info's
+ * destruction.
+ *
+ * - channel_state_ht:
+ * associates a pair (channel key, channel domain) to its last
+ * sampled state received from the consumer daemon
+ * (struct channel_state).
+ * This previous sample is kept to implement edge-triggered
+ * conditions as we need to detect the state transitions.
+ * This hash table owns the channel state.
+ *
+ * - notification_trigger_clients_ht:
+ * associates notification-emitting triggers to clients
+ * (struct notification_client_list) subscribed to those
+ * conditions.
+ * The condition's hash and match functions are used directly since
+ * all triggers in this hash table have the "notify" action.
+ * This hash table holds no ownership.
+ *
+ * - channels_ht:
+ * associates a channel_key to a struct channel_info. The hash table
+ * holds the ownership of the struct channel_info.
+ *
+ * - sessions_ht:
+ * associates a session_name (hash) to a struct session_info. The
+ * hash table holds no ownership of the struct session_info;
+ * the session_info structure is owned by the session's various
+ * channels through their struct channel_info (ref-counting is used).
+ *
+ * - triggers_ht:
+ * associates a trigger to a struct lttng_trigger_ht_element.
+ * The hash table holds the ownership of the
+ * lttng_trigger_ht_elements along with the triggers themselves.
+ * - triggers_by_name_uid_ht:
+ * associates a trigger (name, uid) tuple to
+ * a struct lttng_trigger_ht_element.
+ * The hash table does not hold any ownership and is used strictly
+ * for lookup on registration.
+ * - tracer_event_sources_list:
+ * A list of tracer event source (read side fd) of type
+* struct notification_event_tracer_event_source_element.
+*
+ *
+ * The thread reacts to the following internal events:
+ * 1) creation of a tracing channel,
+ * 2) destruction of a tracing channel,
+ * 3) registration of a trigger,
+ * 4) unregistration of a trigger,
+ * 5) reception of a channel monitor sample from the consumer daemon,
+ * 6) Session rotation ongoing,
+ * 7) Session rotation completed,
+ * 8) registration of a tracer event source,
+ * 9) unregistration of a tracer event source,
+ *
+ * Events specific to notification-emitting triggers:
+ * 9) connection of a notification client,
+ * 10) disconnection of a notification client,
+ * 11) subscription of a client to a conditions' notifications,
+ * 12) unsubscription of a client from a conditions' notifications,
+ *
+ *
+ * 1) Creation of a tracing channel
+ * - notification_trigger_clients_ht is traversed to identify
+ * triggers which apply to this new channel,
+ * - triggers identified are added to the channel_triggers_ht.
+ * - add channel to channels_ht
+ * - if it is the first channel of a session, a session_info is created and
+ * added to the sessions_ht. A list of the triggers associated with that
+ * session is built, and it is added to session_triggers_ht.
+ *
+ * 2) Destruction of a tracing channel
+ * - remove entry from channel_triggers_ht, releasing the list wrapper and
+ * elements,
+ * - remove entry from the channel_state_ht.
+ * - remove channel from channels_ht
+ * - if it was the last known channel of a session, the session_info
+ * structure is torndown, which in return destroys the list of triggers
+ * applying to that session.
+ *
+ * 3) Registration of a trigger
+ * - if the trigger's action is of type "notify",
+ * - traverse the list of conditions of every client to build a list of
+ * clients which have to be notified when this trigger's condition is met,
+ * - add list of clients (even if it is empty) to the
+ * notification_trigger_clients_ht,
+ * - add trigger to channel_triggers_ht (if applicable),
+ * - add trigger to session_triggers_ht (if applicable),
+ * - add trigger to triggers_by_name_uid_ht
+ * - add trigger to triggers_ht
+ * - evaluate the trigger's condition right away to react if that condition
+ * is true from the beginning.
+ *
+ * 4) Unregistration of a trigger
+ * - if the trigger's action is of type "notify",
+ * - remove the trigger from the notification_trigger_clients_ht,
+ * - remove trigger from channel_triggers_ht (if applicable),
+ * - remove trigger from session_triggers_ht (if applicable),
+ * - remove trigger from triggers_by_name_uid_ht
+ * - remove trigger from triggers_ht
+ *
+ * 5) Reception of a channel monitor sample from the consumer daemon
+ * - evaluate the conditions associated with the triggers found in
+ * the channel_triggers_ht,
+ * - if a condition evaluates to "true" and the condition is of type
+ * "notify", query the notification_trigger_clients_ht and send
+ * a notification to the clients.
+ *
+ * 6) Session rotation ongoing
+ *
+ * 7) Session rotation completed
+ *
+ * 8) Registration of a tracer event source
+ * - Add the tracer event source of the application to
+ * tracer_event_sources_list,
+ * - Add the trace event source to the pollset.
+ *
+ * 8) Unregistration of a tracer event source
+ * - Remove the tracer event source of the application from
+ * tracer_event_sources_list,
+ * - Remove the trace event source from the pollset.
+ *
+ * 10) Connection of a client
+ * - add client socket to the client_socket_ht,
+ * - add client socket to the client_id_ht.
+ *
+ * 11) Disconnection of a client
+ * - remove client socket from the client_id_ht,
+ * - remove client socket from the client_socket_ht,
+ * - traverse all conditions to which the client is subscribed and remove
+ * the client from the notification_trigger_clients_ht.
+ *
+ * 12) Subscription of a client to a condition's notifications
+ * - Add the condition to the client's list of subscribed conditions,
+ * - Look-up notification_trigger_clients_ht and add the client to
+ * list of clients.
+ * - Evaluate the condition for the client that subscribed if the trigger
+ * was already registered.
+ *
+ * 13) Unsubscription of a client to a condition's notifications
+ * - Remove the condition from the client's list of subscribed conditions,
+ * - Look-up notification_trigger_clients_ht and remove the client
+ * from the list of clients.
