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>
2019-04-02evmgr: Fix a "maybe uninitialized" issueJosé Bollo1-1/+2
The warning maybe-uninitialized is emited only when the optimisation level is greater than 0. For this reason, the error was not discovered development process. The build config is tuned to detect that error and the error is fixed. Change-Id: I14c8ffe6daa3d498268cfadeab20300895b3360e Signed-off-by: José Bollo <jose.bollo@iot.bzh>
2019-03-29Rename afb-config to afb-argsJosé Bollo8-32/+22
With the introduction of more compilation flags, it becomes interesting to use a configuration file. The configuration file is usually "config.h". So that renaming avoids future ambiguity. It also reflects better what the module does. Change-Id: I952adc1e1bf469132dc224900bd9140ccc51c58b Signed-off-by: José Bollo <jose.bollo@iot.bzh>

2019-03-27evmgr: Isolate the event loop from jobsJosé Bollo4-152/+281
The event loop is renamed evmgr for "event manager" with the intention (1) still use evloop in jobs (2) to provide an abstract event manager/handler/loop abstraction. Change-Id: Ib1955f661f98df80e1c7be99e9fe26a1e06d78f6 Signed-off-by: José Bollo <jose.bollo@iot.bzh>
2019-03-27system & jobs: Reverse link and acquiring eventsJosé Bollo7-39/+81
- The new version of 'systemd_get_event_loop' dont depends anymore on jobs but returns a unique systemd event loop for any threads. - The event loop of jobs now use system.h function instead of the opposite. - The function 'jobs_get_sd_event' is removed - The function 'jobs_acquire_event_manager' is introduced. It is designed to that the current thread can manipulate the single event manager Change-Id: I31fe48dfe0f2cfa4d468e49338d36fea6e7e8081 Signed-off-by: José Bollo <jose.bollo@iot.bzh>

In rare circumstances during intialization threads should wait instead of using a null event loop. This is because no one has needed event loop at this stage of initialization. Change-Id: I05b6ddbc05bec50958d0981213219b1d641401a5 Signed-off-by: Frederic Marec <frederic.marec@iot.bzh>

2019-03-07afb-stub-ws: Allow unordered process of messagesJosé Bollo1-1/+1
Requests are already sequenced on need (noconcurrency flag of bindings). Sequencing messages until their completion has a side effect when dealing with events and synchronous calls: event -> call -> reply locked until event completion (see SPEC-2219). This change could be reverted if events are converted to jobs (see SPEC-2215). Bug-AGL: SPEC-2219 Change-Id: Ia577bc54ba38291817fd5ed3e3dda1b67b2818b7 Signed-off-by: José Bollo <jose.bollo@iot.bzh>

The internal functions blocking threads for implementing call_sync were not releasing the event loop, leading to deafness of the binder.

2018-12-13afb-hsrv: Prepare selection of listening interfacesJose Bollo4-14/+139
The listening socket will no more be the default one but will be the selected ones, with ability to select more than just one listening interface. 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. That evolution depends on a fix of libmicrohttpd to enable at the same time epoll and no-listen-fd.

For bindings v3, it is possible to have no explicit default root API. In that case, the binder creates a fake API that references the binding itself. That api isn't callable be it allows to emit messages, to catch events and to call services (other apis). It must be kept to ensure that there is no further error in the hypothetical case where it is used.

The call to 'afb_require_api' in a preinit was forbiden before binding v3 refactoring. Since v3 it is made possible by deferring the requirement to the initialisation step. But this may lead to bad behaviour if someone use the call to test whether an api exists or not. This commit introduce a message that could warn a developper raising that issue.
