2020-01-07afb-ws-client: Improve direct URIJose Bollo1-2/+5
The direct connection URI was expecting a slash after the port for "tcp:" URI. This slash is not needed because it does not carry any meaning. This change implements the ability to set or not the path of URI. Bug-AGL: SPEC-3094 Change-Id: I3d4c350f4e917759cbf82ccc0d261aa420f6f88a Signed-off-by: Jose Bollo <jose.bollo@iot.bzh>
2020-01-03afb-evt: Ensure unsubscribe worksJose Bollo3-106/+134
Fix the logic of unsubscribing to events. It was not possible before to implment it without tracking every session and context. It was not done because of the required complexity. This implementation ensures that unexpected events lead to a removal of the listener from the list of watchers of the events. The management of the list of watchers is reworked to free unused memory.

2020-01-03afb-apiset: Fix start of apisJose Bollo1-33/+68
When using dynamically created/destroyed API, the binder might miss to start some apis. This fixes that issue by enforcing to restart from beginning until all is initialised. Bug-AGL: SPEC-3087 Change-Id: I4dd8c60c8465419a46132bf9f6deffa11e172e2a Signed-off-by: Jose Bollo <jose.bollo@iot.bzh>

2019-12-12afb-daemon: Fix optionnal portJosé Bollo1-55/+60
Since: - introduction of interface to set the listening port(s) and address(es) - use of nss-localuser for discriminating binders there is no more strict need for exporting the port and substituting it. So the substitution is make only if needed. Since removal of token generation, there is no more need to propoagate any token. The two possibilities are kept for being used whene needed and to ensure sweet transition.

This change allows to specify interfaces to serve explicitely. By default the option --port=PORT lead to serving interface of specification "tcp:*:PORT". Meaning that all interfaces are listened.

The split between context and credentials in requests was somehow artificial and awkward.

2019-12-02afb-hswitch: Update websocket policyJose Bollo1-5/+0
The previous policy for websocket was to enforce them to present a valid token when establishing. This policy is removed because the Websocket API of javascript doesn't provide a way to set the Bearer token in the HTTP header of the negociation (a big miss in my opinion). But because the new policy of token logic is to check the token at each request, it is not more needed to check it at establishment.

Change internals of the protocol WSAPI for the following rationale: 1. Enforce specific declaration and transmission of session identifiers and of access tokens. 2. Lower the size of identifiers to be 16 bits. 3. Introduce protocol versionning through a mechanism of offer/set. The main purpose of that change is to optimize the count of data transmitted. It manages as best as possible the transmission of access tokens the less possible times. Same for sessions that the chage was transmitted at each call.

2019-07-18Tag broadcasted events with UUID and hopJosé Bollo9-38/+138
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.

This commit allow modules of afb-daemon to request UUID. This introduce an abstraction above libuuid for 3 reasons: 1.
