2019-07-12Revert "afb-stub-ws: Allow unordered process of messages"José Bollo1-1/+1
This reverts commit 5425e054fbf87fe6d024103f46e53f2a28e074f2. The change introduced in the reverted commit is no more necessary since events are sent asynchronousely.

2019-07-12afb-evt: send events in separate jobJose Bollo2-42/+227
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).

During its start, when implementing HTTP server, afb-daemon checked that the upload directory was accessible and writable and afb-daemon refused to start when it was not the case. When trying to use systemd's DynamicUser for platform services, it had the effect to forbid service to run. That commit add the directory /tmp as a fallback upload directory.

2019-05-29jobs: Fix infinite wait lockJosé Bollo3-0/+10
The binder was sometime locked until an external event comes. This was discovered during stressing startup test that don't expect external inputs and that then waits for always without terminating. The issue came from a little hole in the management of the state of evmgr object. By design the evmgr has to be synchronised against concurrent accesses not by itself but by the integration. However, the state of "running" wasn't set in the code protected against concurent accesses. The new function allows the integrator to correctly set the state before releasing protection.

2019-04-02Fix false ***buffer overflow*** detectionJosé Bollo11-28/+28
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.

2019-04-02jobs: Refactor exiting jobsJosé Bollo3-74/+63
The new termination function can allow the restart because it doesn't abort the waiting jobs. So after calling 'jobs_exit', all threads stop. The function 'job_start' returns. The threads that are in blocking state, i.e. in a call to 'jobs_enter' or 'jobs_call' are stopped. An error status -1 with errno=EINTR is returned in that case. But before returning, that function calls the exit handler if any. Change-Id: I85a4b1976b09b18804eb681af940531ae5ace6c3 Signed-off-by: José Bollo <jose.bollo@iot.bzh>

Nevertheless, the behavior is not changed at the moment. The default interface (0.0.0.0) is still used. A further change will add the ability to select the listening interfaces.
