For working with +events at least one such context has to be created - allocated, initialized. +Then, events which are meant to be caught and handled have to be registered +within this specific context. Reason for subordinating events to a tevent +context structure rises from the fact that several context can be created and +each of them is processed at different time. So, there can be 1 context +containing just file descriptor events, another one taking care of signal and +time events and the third one which keeps information about the rest. + +Tevent loops are the part of the library which represents the mechanism where +noticing events and triggering handlers actually happens. They accept just one +argument - tevent context structure. Therefore if theoretically an infinity +loop (tevent_loop_wait) was called, only those arguments which belong to the +passed tevent context structure can be caught and invoked within this call. +Although some more signal events were registered (but within some other +context) they will not be noticed. + +@subsection Example + +First lines which handle mem_ctx belong to talloc library +knowledge but because of the fact that tevent uses the talloc library for its +mechanisms it is necessary to understand a bit talloc as well.

List of all available functions which tevent offers for working with +time are listed +here together +with their description. More detailed view at these functions is unnecessary +because their purpose and usage is quite simple and clear. + +@subsection Immediate Immediate event + +These events are, as their name indicates, activated and performed immediately. +It means that this kind of events have priority over others (except signal +events). So if there is a bulk of events registered and after that a +tevent loop is launched, then all the immediate events will be triggered before +the other events. Except other immediate events (and signal events) because +they are also processed sequentially - according the order they were scheduled. +Signals have the highest priority and therefore they are processed +preferentially. Therefore the expression immediate may not correspond exactly +to the dictionary definition of "something without delay" but rather "as soon +as possible" after all preceding immediate events. + +For creating an immediate event there is a small different which lies in the +fact that the creation of such event is done in 2 steps. One represents the +creation (memory allocation), the second one represents registering as the +event within some tevent context. + +@code +struct tevent_immediate *run(TALLOC_CTX* mem_ctx, + struct tevent_context event_ctx, + void * data) +{ + struct tevent_immediate *im; + + im = tevent_create_immediate(mem_ctx); + if (im == NULL) { + return NULL; + } + tevent_schedule_immediate(im, event_ctx, foo, data); + + return im; +} +@endcode + +Example which may be compiled and run representing the creation of immediate event. + +@code + +#include +#include +#include + +struct info_struct { + int counter; +}; + +static void foo(struct tevent_context *ev, struct tevent_immediate *im, + void *private_data) +{ + struct info_struct *data = talloc_get_type_abort(private_data, struct info_struct); + printf("Data value: %d\n", data->counter); +} + +int main (void) { + struct tevent_context *event_ctx; + TALLOC_CTX *mem_ctx; + struct tevent_immediate *im; + + printf("INIT\n"); + + mem_ctx = talloc_new(NULL); + event_ctx = tevent_context_init(mem_ctx); + + struct info_struct *data = talloc(mem_ctx, struct info_struct); + + // setting up private data + data->counter = 1; + + // first immediate event + im = tevent_create_immediate(mem_ctx); + if (im == NULL) { + fprintf(stderr, "FAILED\n"); + return EXIT_FAILURE; + } + tevent_schedule_immediate(im, event_ctx, foo, data); + + tevent_loop_wait(event_ctx); + talloc_free(mem_ctx); + + return 0; +} +@endcode + +@subsection Signal Signal event + +This is an alternative to standard C library functions signal() or sigaction(). +The main difference that distinguishes these ways of treating signals is their +setting up of handlers for different time intervals of the running program. + +While standard C library methods for dealing with signals offer sufficient +tools for most cases, they are inadequate for handling signals within the +tevent loop. It could be necessary to finish certain tevent requests within the +tevent loop without interruption. If a signal was sent to a program at a moment +when the tevent loop is in progress, a standard signal handler would not return +processing to the application at the very same place and it would quit the +tevent loop for ever. In such cases, tevent signal handlers offer the +possibility of dealing with these signals by masking them from the rest of +application and not quitting the loop, so the other events can still be +processed. + +Tevent offers also a control function, which enables us to verify whether it is +possible to handle signals via tevent, is defined within tevent library and it +returns a boolean value revealing the result of the verification. + +@code +bool tevent_signal_support (struct tevent_context *ev) +@endcode + +Checking for signal support is not necessary, but if it is not guaranteed, this +is a good and easy control to prevent unexpected behaviour or failure of the +program occurring. Such a test of course does not have to be run every single +time you wish to create a signal handler, but simply at the beginning - during +the initialization procedures of the program. Afterthat, simply adapt to each +situation that arises. + +@code + +#include +#include +#include + +static void handler(struct tevent_context *ev, + struct tevent_signal *se, + int signum, + int count, + void *siginfo, + void *private_data) +{ + + // Do something useful + + printf("handling signal...\n"); + exit(EXIT_SUCCESS); +} + +int main (void) +{ + struct tevent_context *event_ctx; + TALLOC_CTX *mem_ctx; + struct tevent_signal *sig; + + mem_ctx = talloc_new(NULL); //parent + if (mem_ctx == NULL) { + fprintf(stderr, "FAILED\n"); + return EXIT_FAILURE; + } + + event_ctx = tevent_context_init(mem_ctx); + if (event_ctx == NULL) { + fprintf(stderr, "FAILED\n"); + return EXIT_FAILURE; + } + + if (tevent_signal_support(event_ctx)) { + // create signal event + sig = tevent_add_signal(event_ctx, mem_ctx, SIGINT, 0, handler, NULL); + if (sig == NULL) { + fprintf(stderr, "FAILED\n"); + return EXIT_FAILURE; + } + tevent_loop_wait(event_ctx); + } + + talloc_free(mem_ctx); + return EXIT_SUCCESS; +} +@endcode + + +@subsection File File descriptor event + +Support of events on file descriptors is mainly useful for socket communication +but it certainly works flawlessly with standard streams (stdin, stdout, stderr) + as well. Working asynchronously with file descriptors enables switching + within processing I/O operations. This ability may rise with a greater + number of I/O operations and such overlapping leads to enhancement of the + throughput. + +There are several other functions included in tevent API related to handling +file descriptors (there are too many functions defined within tevent therefore +just some of them are fully described within this thesis.

When working with tevent request it +is possible to nest one event under another and handle them bit by bit. This +enables the creation of sequences of steps, and provides an opportunity to +prepare for all problems which may unexpectedly happen within the different +phases. One way or another, subrequests split bigger tasks into smaller ones +which allow a clearer view of each task as a whole. + +@subsection name Naming conventions + +There is a naming convention which is not obligatory but it is followed in this +tutorial: + +- Functions triggered before the event happens. These establish a request. +- \b foo_send(...) - this function is called first and it includes the + creation of tevent request - tevent req structure. It does not block + anything, it simply creates a request, sets a callback (foo done) and lets + the program continue +- Functions as a result of event. +- \b foo_done(...) - this function contains code providing for handling itself + and based upon its results, the request is set either as a done or, if an + error occurs, the request is set as a failure. +- \b foo_recv(...) - this function contains code which should, if demanded, + access the result data and make them further visible. The foo state should + be deallocated from memory when the request’s processing is over and + therefore all computed data up to this point would be lost. + +As was already mentioned, specific naming subsumes not only functions but also +the data themselves: + +- \b foo_state - this is a structure. It contains all the data necessary for + the asynchronous task. + +@subsection cr_req Creating a New Asynchronous Request + +The first step for working asynchronously is the allocation of memory +requirements. As in previous cases, the talloc context is required, upon which +the asynchronous request will be tied. The next step is the creation of the +request itself. + +@code +struct tevent_req* tevent_req_create (TALLOC_CTX *mem_ctx, void **pstate, #type) +@endcode + +The pstate is the pointer to the private data. The necessary amount of memory +(based on data type) is allocated during this call. Within this same memory +area all the data from the asynchronous request that need to be preserved for +some time should be kept. + +Dealing with a lack of memory + +The verification of the returned pointer against NULL is necessary in order to +identify a potential lack of memory. There is a special function which helps +with this check tevent_req_nomem(). + +It handles verification both of the talloc memory allocation and of the +associated tevent request, and is therefore a very useful function for avoiding +unexpected situations. It can easily be used when checking the availability of +further memory resources that are required for a tevent request. Imagine an +example where additional memory needs arise although no memory resources are +currently available. + +@code +bar = talloc(mem_ctx, struct foo); +if(tevent_req_nomem (bar, req)) { + // handling a problem +} +@endcode + +This code ensures that the variable bar, which contains NULL as a result of the +unsuccessful satisfaction of its memory requirements, is noticed, and also that +the tevent request req declares it exceeds memory capacity, which implies the +impossibility of finishing the request as originally programmed. + + +@subsection fini_req Finishing a Request + +Marking each request as finished is an essential principle of the tevent +library. Without marking the request as completed - either successfully or with +an error - the tevent loop could not let the appropriate callback be triggered. +It is important to understand that this would be a significant threat, because +it is not usually a question of one single function which prints some text on a +screen, but rather the request is itself probably just a link in a series of +other requests. Stopping one request would stop the others, memory resources +would not be freed, file descriptors might remain open, communication via +socket could be interrupted, and so on. Therefore it is important to think +about finishing requests, either successfully or not, and also to prepare +functions for all possible scenarios, so that the the callbacks do not process +data that are actually invalid or, even worse, in fact non-existent meaning +that a segmentation fault may arise. + +
    +
  • \b Manually - This is the most common type of finishing request. Calling +this function sets the request as a TEVENT_REQ_DONE. This is the only purpose +of this function and it should be used when everything went well. Typically it +is used within the done functions. + +@code +void tevent_req_done (struct tevent_req *req) +@endcode +Alternatively, the request can end up being unsuccessful. +@code +bool tevent_req_error (struct tevent_req *req, uint64_t error) +@endcode + +The second argument takes the number of an error (declared by the programmer, +for example in an enumerated variable). The function tevent_req_error() sets +the status of the request as a TEVENT_REQ_USER_ERROR and also stores the code +of error within the structure so it can be used, for example for debugging. The +function returns true, if marking the request as an error was processed with no +problem - value error passed to this function is not equal to 1.
    • + +
  • +Setting up a timeout for request - A request can be finished virtually, +or if the process takes too much time, it can be timed out. This is considered +as an error of the request and it leads to calling callback. In the +background, this timeout is set through a time event (described in +@subpage tevent_events ) which eventually triggers an operation marking the +request as a TEVENT_REQ_TIMED_OUT (can not be considered as successfully +finished). In case a time out was already set, this operation will overwrite it +with a new time value (so the timeout may be lengthened) and if everything is +set properly, it returns true. + +@code +bool tevent_req_set_endtime(struct tevent_req *req, + struct tevent_context *ev, + struct timeval endtime); +@endcode +
    • + + +
  • Premature Triggering - Imagine a situation in which some part of a +nested subrequest ended up with a failure and it is still required to trigger a +callback. Such as example might result from lack of memory leading to the +impossibility of allocating enough memory requirements for the event to start +processing another subrequest, or from a clear intention to skip other +procedures and trigger the callback regardless of other progress. In these +cases, the function tevent_req_post() is very handy and offers this option. + +@code +struct tevent_req* tevent_req_post (struct tevent_req *req, + struct tevent_context *ev); +@endcode + +A request finished in this way does not behave as a time event nor as a file +descriptor event but as a immediately scheduled event, and therefore it will be +treated according the description laid down in @subpage tevent_events . +
    • +
+ + +@section nested Subrequests - Nested Requests + +To create more complex and interconnected asynchronous operations, it is +possible to submerge a request into another and thus create a so-called +subrequest.

This can be built +out of the basic functions and isolation mechanisms of tevent, +but tevent also comes with some utility functions that make +this easier, so long as you understand the limitations that +using threads with talloc and tevent impose. + +To allow a tevent context to receive an asynchronous tevent_immediate +function callback from another thread, create a struct tevent_thread_proxy * +by calling @code + +struct tevent_thread_proxy *tevent_thread_proxy_create( + struct tevent_context *dest_ev_ctx); + +@endcode + +This function allocates the internal data structures to +allow asynchronous callbacks as a talloc child of the +struct tevent_context *, and returns a struct tevent_thread_proxy * +that can be passed to another thread. + +When you have finished receiving asynchronous callbacks, simply +talloc_free the struct tevent_thread_proxy *, or talloc_free +the struct tevent_context *, which will deallocate the resources +used. + +To schedule an asynchronous tevent_immediate function call from one +thread on the tevent loop of another thread, use +@code + +void tevent_thread_proxy_schedule(struct tevent_thread_proxy *tp, + struct tevent_immediate **pp_im, + tevent_immediate_handler_t handler, + void **pp_private_data); + +@endcode + +This function causes the function handler() +to be invoked as a tevent_immediate callback from the event loop +of the thread that created the struct tevent_thread_proxy * +(so the owning struct tevent_context * should be +long-lived and not in the process of being torn down). + +The struct tevent_thread_proxy object being +used here is a child of the event context of the target +thread. So external synchronization mechanisms must be +used to ensure that the target object is still in use +at the time of the tevent_thread_proxy_schedule() +call. In the example below, the request/response nature +of the communication ensures this. + +The struct tevent_immediate **pp_im passed into this function +should be a struct tevent_immediate * allocated on a talloc context +local to this thread, and will be reparented via talloc_move +to be owned by struct tevent_thread_proxy *tp. +*pp_im will be set to NULL on successful scheduling +of the tevent_immediate call. + +handler() will be called as a normal tevent_immediate +callback from the struct tevent_context * of the destination +event loop that created the struct tevent_thread_proxy * + +Returning from this functions does not mean that the handler +has been invoked, merely that it has been scheduled to be called in the +destination event loop. + +Because the calling thread does not wait for the +callback to be scheduled and run on the destination +thread, this is a fire-and-forget call. If you wish +confirmation of the handler() being +successfully invoked, you must ensure it replies to the +caller in some way. + +Because of asynchronous nature of this call, the nature +of the parameter passed to the destination thread has some +restructions. If you don't need parameters, merely pass +NULL as the value of +void **pp_private_data. + +If you wish to pass a pointer to data between the threads, +it MUST be a pointer to a talloced pointer, which is +not part of a talloc-pool, and it must not have a destructor +attached. The ownership of the memory pointed to will +be passed from the calling thread to the tevent library, +and if the receiving thread does not talloc-reparent +it to its own contexts, it will be freed once the +handler is called. + +On success, *pp_private will be NULL +to signify the talloc memory ownership has been moved. + +In practice for message passing between threads in +event loops these restrictions are not very onerous. + +The easiest way to to a request-reply pair between +tevent loops on different threads is to pass the +parameter block of memory back and forth using +a reply tevent_thread_proxy_schedule() +call. + +Here is an example (without error checking for +simplicity): + +@code +------------------------------------------------ +// Master thread. + +main() +{ + // Make talloc thread-safe. + + talloc_disable_null_tracking(); + + // Create the master event context. + + struct tevent_context *master_ev = tevent_context_init(NULL); + + // Create the master thread proxy to allow it to receive + // async callbacks from other threads. + + struct tevent_thread_proxy *master_tp = + tevent_thread_proxy_create(master_ev); + + // Create sub-threads, passing master_tp in + // some way to them. + // This code not shown.. + + // Process events. + // Function master_callback() below + // will be invoked on this thread on + // master_ev event context. + + tevent_loop_wait(master_ev); + + // Cleanup if loop exits. + + talloc_free(master_ev); +} + +// Data passed between threads. +struct reply_state { + struct tevent_thread_proxy *reply_tp; + pthread_t thread_id; + bool *p_finished; +}; + +// Callback Called in child thread context. + +static void thread_callback(struct tevent_context *ev, + struct tevent_immediate *im, + void *private_ptr) +{ + // Move the ownership of what private_ptr + // points to from the tevent library back to this thread. + + struct reply_state *rsp = + talloc_get_type_abort(private_ptr, struct reply_state); + + talloc_steal(ev, rsp); + + *rsp->p_finished = true; + + // im will be talloc_freed on return from this call. + // but rsp will not. +} + +// Callback Called in master thread context. + +static void master_callback(struct tevent_context *ev, + struct tevent_immediate *im, + void *private_ptr) +{ + // Move the ownership of what private_ptr + // points to from the tevent library to this thread. + + struct reply_state *rsp = + talloc_get_type_abort(private_ptr, struct reply_state); + + talloc_steal(ev, rsp); + + printf("Callback from thread %s\n", thread_id_to_string(rsp->thread_id)); + + /* Now reply to the thread !

Do not ever put any localised hacks in here, instead + register one of the possible event types and implement that event + somewhere else. + + There are 2 types of event handling that are handled in this module: + + 1) a file descriptor becoming readable or writeable. This is mostly + used for network sockets, but can be used for any type of file + descriptor. You may only register one handler for each file + descriptor/io combination or you will get unpredictable results + (this means that you can have a handler for read events, and a + separate handler for write events, but not two handlers that are + both handling read events) + + 2) a timed event. You can register an event that happens at a + specific time. You can register as many of these as you + like. They are single shot - add a new timed event in the event + handler to get another event. + + To setup a set of events you first need to create a event_context + structure using the function tevent_context_init(); This returns a + 'struct tevent_context' that you use in all subsequent calls. + + After that you can add/remove events that you are interested in + using tevent_add_*() and talloc_free() + + Finally, you call tevent_loop_wait_once() to block waiting for one of the + events to occor or tevent_loop_wait() which will loop + forever. + +*/ +#include "replace.h" +#include "system/filesys.h" +#ifdef HAVE_PTHREAD +#include "system/threads.h" +#endif +#define TEVENT_DEPRECATED 1 +#include "tevent.h" +#include "tevent_internal.h" +#include "tevent_util.h" +#ifdef HAVE_EVENTFD +#include +#endif + +struct tevent_ops_list { + struct tevent_ops_list *next, *prev;

In particular the + * file descriptor (tevent_add_fd) and timer (tevent_add_timed) events + * are considered too low-level to be used in larger computations. To + * read and write from and to sockets, Samba provides two calls on top + * of tevent_add_fd: tstream_read_packet_send/recv and tstream_writev_send/recv. + * These requests are much easier to compose than the low-level event + * handlers called from tevent_add_fd. + * + * A lot of the simplicity tevent_req has brought to the notoriously + * hairy async programming came via a set of conventions that every + * async computation programmed should follow. One central piece of + * these conventions is the naming of routines and variables. + * + * Every async computation needs a name (sensibly called "computation" + * down from here). From this name quite a few naming conventions are + * derived. + * + * Every computation that requires local state needs a + * @code + * struct computation_state { + * int local_var; + * }; + * @endcode + * Even if no local variables are required, such a state struct should + * be created containing a dummy variable. Quite a few helper + * functions and macros (for example tevent_req_create()) assume such + * a state struct. + * + * An async computation is started by a computation_send + * function. When it is finished, its result can be received by a + * computation_recv function. For an example how to set up an async + * computation, see the code example in the documentation for + * tevent_req_create() and tevent_req_post(). The prototypes for _send + * and _recv functions should follow some conventions: + * + * @code + * struct tevent_req *computation_send(TALLOC_CTX *mem_ctx, + * struct tevent_context *ev, + * ... further args); + * int computation_recv(struct tevent_req *req, ... further output args); + * @endcode + * + * The "int" result of computation_recv() depends on the result the + * sync version of the function would have, "int" is just an example + * here. + * + * Another important piece of the conventions is that the program flow + * is interrupted as little as possible. Because a blocking + * sub-computation requires that the flow needs to continue in a + * separate function that is the logical sequel of some computation, + * it should lexically follow sending off the blocking + * sub-computation. Setting the callback function via + * tevent_req_set_callback() requires referencing a function lexically + * below the call to tevent_req_set_callback(), forward declarations + * are required. A lot of the async computations thus begin with a + * sequence of declarations such as + * + * @code + * static void computation_step1_done(struct tevent_req *subreq); + * static void computation_step2_done(struct tevent_req *subreq); + * static void computation_step3_done(struct tevent_req *subreq); + * @endcode + * + * It really helps readability a lot to do these forward declarations, + * because the lexically sequential program flow makes the async + * computations almost as clear to read as a normal, sync program + * flow. + * + * It is up to the user of the async computation to talloc_free it + * after it has finished. If an async computation should be aborted, + * the tevent_req structure can be talloc_free'ed. After it has + * finished, it should talloc_free'ed by the API user. + * + * tevent_req variable naming conventions: + * + * The name of the variable pointing to the tevent_req structure + * returned by a _send() function SHOULD be named differently between + * implementation and caller. + * + * From the point of view of the implementation (of the _send() and + * _recv() functions) the variable returned by tevent_req_create() is + * always called @em req. + * + * While the caller of the _send() function should use @em subreq to + * hold the result. + * + * @see tevent_req_create() + * @see tevent_req_fn() + * + * @{ + */ + +/** + * An async request moves from TEVENT_REQ_INIT to + * TEVENT_REQ_IN_PROGRESS.
