2019-07-18Tag broadcasted events with UUID and hopJosé Bollo10-39/+139
When API have mutual dependencies, leading to loops in dependecies, broadcasting an event never ends because of the loop (see SPEC-2625). To avoid that weird flood of events, a unic identifier (UUID) is attached to broadcasted event and a tiny memory records previously broadcasted events to avoid re-sending an already sent event. The size of the memory can be set using the macro variable EVENT_BROADCAST_MEMORY_COUNT whose default value is 8. It can be reduced to 0. An other mecanism is added to limit the count of hops that a broadcasted event can do. That count can be set using the macro variable EVENT_BROADCAST_HOP_MAX whose default value is 10.

2019-07-18afb-evt: Refactor processing of broadcasted eventsJosé Bollo6-83/+68
Solving the bug SPEC-2625 needs to rework the broadcasting of events. It appeared that the numerical event identifier passed for broadcast wasn't used by called function except for hooking. Suppressing it introduces a clear distinction between the push and the broadcast paths. The file afb-ws-json1 is changed to avoid casting of functions.

2019-07-18uuid: Add module for UUID generationJosé Bollo4-70/+125
This commit allow modules of afb-daemon to request UUID. This introduce an abstraction above libuuid for 3 reasons: 1. Using uuid had bad side effect inthe past because it required enought entropy at start time, leading to hanging initialisations in wait for enough entropy. 2. Solving bug SPEC-2625 will require use of UUID. 3. Porting to systems that haven't libuuid is made more easy after that.

2019-07-12afb-xreq: Forbids (un)subscribes after replyJose Bollo4-12/+32
Allowing to subscribe to a request that was replied was possible and lead to problem revealed by issues SPEC-2542 and SPEC-2599 (these issues are more related to processing unordered incoming messages). The choice was - fix the bug and authorize (un)subscribe after reply - forbids to (un)subscribe after reply Second solution was chosen for its simplicity and its networking efficiency.

2019-07-12afb-evt: send events in separate jobJose Bollo7-46/+239
Sending events in the context of the calling process had the consequence that the ordering of the messages had to be removed (see SPEC-2215 & SPEC-2219). This was not good by nature and lead to issues SPEC-2542 and SPEC-2599. Sending events in the context of the calling process also implies to delay the calling process. For this reasons, sending events is now done in an other jobs. For that reason, the count of allowed pending jobs is increased to 100 (was 50).

2019-04-02Fix false ***buffer overflow*** detectionJosé Bollo12-29/+29
The compiling option __FORTIFY_SOURCE=2 introduced a false ***buffer overflow*** detection when the flexible array 'pattern' was initilized in globset. The compiler is only complaining when the array is in a struct that is in a struct like struct { ...; struct { ...; char name[1]; }} To avoid these false detections, it is enougth to ellipsese the dimension of the array. Seems to be the now standard way of declaring flexible arrays when it was before an extension. So now: struct { ...; struct { ...; char name[]; }} works even when __FORTIFY_SOURCE=2.
