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 event_context_init(); This returns a - 'struct event_context' that you use in all subsequent calls. - - After that you can add/remove events that you are interested in - using event_add_*() and talloc_free() - - Finally, you call event_loop_wait_once() to block waiting for one of the - events to occor or event_loop_wait() which will loop - forever. - -*/ -#include "replace.h" -#include "events.h" -#include "events_internal.h" -#include "events_util.h" - -struct event_ops_list { - struct event_ops_list *next, *prev; - const char *name; - const struct event_ops *ops; -}; - -/* list of registered event backends */ -static struct event_ops_list *event_backends = NULL; -static char *event_default_backend = NULL; - -/* - register an events backend -*/ -bool event_register_backend(const char *name, const struct event_ops *ops) -{ - struct event_ops_list *e; - - for (e = event_backends; e != NULL; e = e->next) { - if (0 == strcmp(e->name, name)) { - /* already registered, skip it */ - return true; - } - } - - e = talloc(talloc_autofree_context(), struct event_ops_list); - if (e == NULL) return false; - - e->name = name; - e->ops = ops; - DLIST_ADD(event_backends, e); - - return true; -} - -/* - set the default event backend - */ -void event_set_default_backend(const char *backend) -{ - if (event_default_backend) free(event_default_backend); - event_default_backend = strdup(backend); -} - -/* - initialise backends if not already done -*/ -static void event_backend_init(void) -{ - events_select_init(); - events_standard_init(); -#if HAVE_EVENTS_EPOLL - events_epoll_init(); -#endif -#if HAVE_LINUX_AIO - events_aio_init(); -#endif -} - -/* - list available backends -*/ -const char **event_backend_list(TALLOC_CTX *mem_ctx) -{ - const char **list = NULL; - struct event_ops_list *e; - - event_backend_init(); - - for (e=event_backends;e;e=e->next) { - list = ev_str_list_add(list, e->name); - } - - talloc_steal(mem_ctx, list); - - return list; -} - -/* - create a event_context structure for a specific implemementation. - This must be the first events call, and all subsequent calls pass - this event_context as the first element.

Also, since swig_type_info structures store pointers to - * swig_cast_info structures and swig_cast_info structures store pointers back - * to swig_type_info structures, we need some lookup code at initialization. - * The idea is that swig generates all the structures that are needed. - * The runtime then collects these partially filled structures. - * The SWIG_InitializeModule function takes these initial arrays out of - * swig_module, and does all the lookup, filling in the swig_module.types - * array with the correct data and linking the correct swig_cast_info - * structures together. - * - * The generated swig_type_info structures are assigned staticly to an initial - * array. We just loop through that array, and handle each type individually. - * First we lookup if this type has been already loaded, and if so, use the - * loaded structure instead of the generated one. Then we have to fill in the - * cast linked list. The cast data is initially stored in something like a - * two-dimensional array. Each row corresponds to a type (there are the same - * number of rows as there are in the swig_type_initial array). Each entry in - * a column is one of the swig_cast_info structures for that type. - * The cast_initial array is actually an array of arrays, because each row has - * a variable number of columns. So to actually build the cast linked list, - * we find the array of casts associated with the type, and loop through it - * adding the casts to the list. The one last trick we need to do is making - * sure the type pointer in the swig_cast_info struct is correct. - * - * First off, we lookup the cast->type name to see if it is already loaded. - * There are three cases to handle: - * 1) If the cast->type has already been loaded AND the type we are adding - * casting info to has not been loaded (it is in this module), THEN we - * replace the cast->type pointer with the type pointer that has already - * been loaded. - * 2) If BOTH types (the one we are adding casting info to, and the - * cast->type) are loaded, THEN the cast info has already been loaded by - * the previous module so we just ignore it. - * 3) Finally, if cast->type has not already been loaded, then we add that - * swig_cast_info to the linked list (because the cast->type) pointer will - * be correct. - * ----------------------------------------------------------------------------- */ - -#ifdef __cplusplus -extern "C" { -#if 0 -} /* c-mode */ -#endif -#endif - -#if 0 -#define SWIGRUNTIME_DEBUG -#endif - - -SWIGRUNTIME void -SWIG_InitializeModule(void *clientdata) { - size_t i; - swig_module_info *module_head, *iter; - int found, init; - - clientdata = clientdata; - - /* check to see if the circular list has been setup, if not, set it up */ - if (swig_module.next==0) { - /* Initialize the swig_module */ - swig_module.type_initial = swig_type_initial; - swig_module.cast_initial = swig_cast_initial; - swig_module.next = &swig_module; - init = 1; - } else { - init = 0; - } - - /* Try and load any already created modules */ - module_head = SWIG_GetModule(clientdata); - if (!module_head) { - /* This is the first module loaded for this interpreter */ - /* so set the swig module into the interpreter */ - SWIG_SetModule(clientdata, &swig_module); - module_head = &swig_module; - } else { - /* the interpreter has loaded a SWIG module, but has it loaded this one?
