Glib实现了完整的事件循环分发机制，每个主循环负责处理各种事件，事件通过事件源描述。
每个事件源都会关联一个GMainCOntext，一个线程只能运行一个GMaincontext，但是其它线程能够对事件源进行添加和删除操作。
// 代表一个主事件循环，通过g_main_loop_new来创建，在添加完毕初始事件源后执行
// g_main_loop_run() 主循环将持续不断的检查每个事件源产生的新事件，然后分发它们，、
//最后通过g_main_loop_quit（）退出
struct _GMainLoop
{
GMainContext *context;
gboolean is_running; /* (atomic) */
gint ref_count; /* (atomic) */
};
struct _GMainContext
{
/* The following lock is used for both the list of sources
* and the list of poll records
*/
GMutex mutex;
GCond cond;
GThread *owner;
guint owner_count;
GMainContextFlags flags;
GSList *waiters;
gint ref_count; /* (atomic) */
GHashTable *sources; /* guint -> GSource */
GPtrArray *pending_dispatches;
gint timeout; /* Timeout for current iteration */
guint next_id;
GList *source_lists;
gint in_check_or_prepare;
GPollRec *poll_records;
guint n_poll_records;
GPollFD *cached_poll_array;
guint cached_poll_array_size;
GWakeup *wakeup;
GPollFD wake_up_rec;
/* Flag indicating whether the set of fd's changed during a poll */
gboolean poll_changed;
GPollFunc poll_func;
gint64 time;
gboolean time_is_fresh;
};
//每个事件源
struct _GSource
{
/*< private >*/
gpointer callback_data;
// 所有事件源的回调函数
GSourceCallbackFuncs *callback_funcs;
const GSourceFuncs *source_funcs;
guint ref_count;
GMainContext *context;
gint priority;
guint flags;
guint source_id;
GSList *poll_fds;// 监听的fd
GSource *prev;
GSource *next;
char *name;
GSourcePrivate *priv;
};
struct _GSourceFuncs
{
gboolean (*prepare) (GSource *source,
gint *timeout_);/* Can be NULL */
gboolean (*check) (GSource *source);/* Can be NULL */
gboolean (*dispatch) (GSource *source,
GSourceFunc callback,
gpointer user_data);
void (*finalize) (GSource *source); /* Can be NULL */
/*< private >*/
/* For use by g_source_set_closure */
GSourceFunc closure_callback;
GSourceDummyMarshal closure_marshal; /* Really is of type GClosureMarshal */
};
上面三个核心结构体就是整个事件的核心，GSource代表一个事件源，内部有一个回调函数，当该事件源有事件发生的时候就触发该函数。
另外事件源有四个函数prepare、check、dispatch以及finalize，这四个函数代表了了一个事件源的生命不同周期：
prepare : 设置检查事件时间超时。如果返回 TRUE, check 会立刻被调用；如果返回 FALSE 并设置了 timeout ， timeout 时间后 check 会被调用。
check ： 检查事件是否准备完毕。返回 TRUE 为准备完毕， dispatch 会被立刻调用；返回 FALSE 不调用 dispatch，进入下一次事件循环。
dispatch : 分发事件。返回 TRUE 将继续下一次操作循环；返回 FALSE 中止本事件源的事件循环。
finalize : 当事件源被移除时被调用。

如下代码是对调用的分析：
GMainLoop *
g_main_loop_new (GMainContext *context,
gboolean is_running)
{
GMainLoop *loop;
if (!context)
context = g_main_context_default();
g_main_context_ref (context);
loop = g_new0 (GMainLoop, 1);
loop->context = context;
loop->is_running = is_running != FALSE;
loop->ref_count = 1;
TRACE (GLIB_MAIN_LOOP_NEW (loop, context));
return loop;
}
void
g_main_loop_run (GMainLoop *loop)
{
GThread *self = G_THREAD_SELF;
g_return_if_fail (loop != NULL);
g_return_if_fail (g_atomic_int_get (&loop->ref_count) > 0);
[...]
g_atomic_int_set (&loop->is_running, TRUE);
while (g_atomic_int_get (&loop->is_running))
g_main_context_iterate (loop->context, TRUE, TRUE, self);
UNLOCK_CONTEXT (loop->context);
g_main_context_release (loop->context);
g_main_loop_unref (loop);
}
/* HOLDS context lock */
static gboolean
g_main_context_iterate (GMainContext *context,
gboolean block,
gboolean dispatch,
GThread *self)
{
//[...]
// prepare阶段
g_main_context_prepare (context, &max_priority);
while ((nfds = g_main_context_query (context, max_priority, &timeout, fds,
allocated_nfds)) > allocated_nfds)
{
LOCK_CONTEXT (context);
g_free (fds);
context->cached_poll_array_size = allocated_nfds = nfds;
context->cached_poll_array = fds = g_new (GPollFD, nfds);
UNLOCK_CONTEXT (context);
}
if (!block)
timeout = 0;
g_main_context_poll (context, timeout, max_priority, fds, nfds);
// check 阶段
some_ready = g_main_context_check (context, max_priority, fds, nfds);
//分发阶段
if (dispatch)
g_main_context_dispatch (context);
g_main_context_release (context);
// [...]
return some_ready;
}
Glib实现了一个功能强大的事件循环分发处理机制，Glib内部提供三种类型的事件源：
glib中已经提供了几个GSource的子类，其中的g_timeout_source_new(guint interval)和g_idle_source_new(void)这两个函数构造出的GSource子类，就并不使用文件描述符号。
GTimeoutSource，只需要保存设定的间隔时间，在poll轮循的prepare和check阶段，会去检查设定的这个间隔时间是否到达，如果到达设定的时间，则它的dispatch函数会被调用。
g_idle_source_new(void)其实都没有继承GSource，它也不需要和文件绑定，只不过它的优先级比较低，只有在poll轮询的空闲阶段，它的dispatch函数会被调用。而它的prepare和check函数，始终都是返回的TRUE。
Timeout事件源使用案例：
/* test.c */
int main(int argc, char const *argv[]) {
/* 1.创建一个 GMainLoop 结构体对象，作为一个主事件循环 */
GMainLoop *loop = g_main_loop_new(NULL, FALSE);
/* 2.添加超时事件源 */
g_timeout_add(1000, count_down, NULL);
g_timeout_add(8000, cancel_fire, loop);
/* 3.添加空闲函数，没有更高优先级事件时，空闲函数就可以被执行 */
g_idle_add(say_idle, NULL);
/* 4.循环检查事件源中是否有新事件进行分发，当某事件处理函数调用 g_main_loop_quit()，函数退出 */
g_main_loop_run(loop);
/* 5.减少loop引用计数，如果计数为0，则会释放loop资源 */
g_main_loop_unref(loop);
return 0;
}

Glib提供了线程池和线程处理函数，首先会创建一个线程池，当有数据要处理的时候就把数据交给其中一个线程，处理完毕后再归还给线程池。

多线程异步队列：
所有的数据组织成队列，供多线程并发访问，而这些并发控制全部在异步队列里面实现，对外面只提供读写接口；当队列中的数据为空时， 如果是读线程访问异步队列，那么这一读线程就等待，直到有数据为止；写线程向队列放数据时，如果有线程在等待数据就唤醒等待线程。
异步队列提供接口函数，提供两种类型，无锁和带锁：
typedef struct _GAsyncQueue GAsyncQueue;
// 异步队列的创建
GAsyncQueue * g_async_queue_new ()
GAsyncQueue * g_async_queue_new_full ()
// 异步队列的操作
GAsyncQueue * g_async_queue_ref ()
void g_async_queue_unref ()
void g_async_queue_push ()
void g_async_queue_push_sorted ()
void g_async_queue_push_front ()
gboolean g_async_queue_remove ()
gpointer g_async_queue_pop ()
gpointer g_async_queue_try_pop ()
gpointer g_async_queue_timeout_pop ()
gint g_async_queue_length ()
void g_async_queue_sort ()
// 异步队列带锁和不带锁
void g_async_queue_lock ()
void g_async_queue_unlock ()
void g_async_queue_ref_unlocked ()
void g_async_queue_unref_and_unlock ()
void g_async_queue_push_unlocked ()
void g_async_queue_push_sorted_unlocked ()
void g_async_queue_push_front_unlocked ()
gboolean g_async_queue_remove_unlocked ()
gpointer g_async_queue_pop_unlocked ()
gpointer g_async_queue_try_pop_unlocked ()
gpointer g_async_queue_timeout_pop_unlocked ()
gint g_async_queue_length_unlocked ()
void g_async_queue_sort_unlocked ()
gpointer g_async_queue_timed_pop ()
gpointer g_async_queue_timed_pop_unlocked ()
案例：
#include <glib.h>
static gpointer test_aqueue_push_func(gpointer data)
{
GAsyncQueue *aqueue = NULL;
g_print("%s \n", __FUNCTION__);
g_print("delay 2 seconds to push data \n");
g_usleep(2*1000*1000);
aqueue = (GAsyncQueue *)data;
g_async_queue_push(aqueue, GINT_TO_POINTER(99));
return NULL;
}
static gpointer test_aqueue_pop_func(gpointer data)
{
gpointer val = NULL;
GAsyncQueue *aqueue = NULL;
g_print("%s \n", __FUNCTION__);
aqueue = (GAsyncQueue *)data;
val = g_async_queue_pop(aqueue);
g_print("val: %d \n", GPOINTER_TO_INT(val));
return NULL;
}
gint main(gint argc, gchar **argv)
{
GThread *thd_push, *thd_pop;
GAsyncQueue *aqueue = NULL;
aqueue = g_async_queue_new();
thd_push = g_thread_new("thd_push", test_aqueue_push_func, aqueue);
thd_pop = g_thread_new("thd_pop", test_aqueue_pop_func, aqueue);
g_thread_join(thd_push);
g_thread_join(thd_pop);
g_async_queue_unref(aqueue);
return 0;
}
线程池：
线程池是在多线程编程时经常用到的技术。在进行多线程任务处理时，如果线程频繁创建和销毁，将会使系统开销变大，在这种情况下，上一个任务执行完后不销毁之前创建的线程，后续任务重用该线程，将会大大减小开销。为了管理这些创建之后不再销毁的线程，便有了线程池的概念。
GLib的线程池除了提供一般的线程池函数外，还提供了诸如获取当前运行的线程数量、获取未处理的任务数量、获取或设置线程池的最大线程数量、获取未使用的线程数量、设置未使用的最大线程数量、停止所有目前未使用的线程，但经过实际测试，这里面有些功能并未生效。
