+
+## ORM Operations
+
+### 1. Retrieving instance
+```go
+db := g.DB()
+db := g.DB("user-center")
+```
+### 2. Chaining Operations
+
+`Where + string`
+```go
+// SELECT * FROM user WHERE uid>1 LIMIT 0,10
+r, err := db.Table("user").Where("uid > ?", 1).Limit(0, 10).Select()
+
+// SELECT uid,name FROM user WHERE uid>1 LIMIT 0,10
+r, err := db.Table("user").Fileds("uid,name").Where("uid > ?", 1).Limit(0, 10).Select()
+
+// SELECT * FROM user WHERE uid=1
+r, err := db.Table("user").Where("u.uid=1",).One()
+r, err := db.Table("user").Where("u.uid", 1).One()
+r, err := db.Table("user").Where("u.uid=?", 1).One()
+// SELECT * FROM user WHERE (uid=1) AND (name='john')
+r, err := db.Table("user").Where("uid", 1).Where("name", "john").One()
+r, err := db.Table("user").Where("uid=?", 1).And("name=?", "john").One()
+// SELECT * FROM user WHERE (uid=1) OR (name='john')
+r, err := db.Table("user").Where("uid=?", 1).Or("name=?", "john").One()
+```
+`Where + map`
+```go
+// SELECT * FROM user WHERE uid=1 AND name='john'
+r, err := db.Table("user").Where(g.Map{"uid" : 1, "name" : "john"}).One()
+// SELECT * FROM user WHERE uid=1 AND age>18
+r, err := db.Table("user").Where(g.Map{"uid" : 1, "age>" : 18}).One()
+```
+`Where + struct/*struct`
+```go
+type User struct {
+    Id       int    `json:"uid"`
+    UserName string `gconv:"name"`
+}
+// SELECT * FROM user WHERE uid =1 AND name='john'
+r, err := db.Table("user").Where(User{ Id : 1, UserName : "john"}).One()
+// SELECT * FROM user WHERE uid =1
+r, err := db.Table("user").Where(&User{ Id : 1}).One()
+```
+### 3. Update & Delete
+```go
+// UPDATE user SET name='john guo' WHERE name='john'
+r, err := db.Table("user").Data(gdb.Map{"name" : "john guo"}).Where("name=?", "john").Update()
+r, err := db.Table("user").Data("name='john guo'").Where("name=?", "john").Update()
+// UPDATE user SET status=1 ORDER BY login_time asc LIMIT 10
+r, err := db.Table("user").Data("status", 1).OrderBy("login_time asc").Limit(10).Update
+
+// DELETE FROM user WHERE uid=10
+r, err := db.Table("user").Where("uid=?", 10).Delete()
+// DELETE FROM user ORDER BY login_time asc LIMIT 10
+r, err := db.Table("user").OrderBy("login_time asc").Limit(10).Delete()
+```
+### 4. Insert & Replace & Save
+```go
+r, err := db.Table("user").Data(g.Map{"name": "john"}).Insert()
+r, err := db.Table("user").Data(g.Map{"uid": 10000, "name": "john"}).Replace()
+r, err := db.Table("user").Data(g.Map{"uid": 10001, "name": "john"}).Save()
+```
+### 5. Transaction
+```go
+if tx, err := db.Begin(); err == nil {
+    r, err := tx.Save("user", g.Map{
+        "uid"  :  1,
+        "name" : "john",
+    })
+    tx.Commit()
+}
+```
+### 6. Error Handling
+```go
+func GetOrderInfo(id int) (order *Order, err error) {
+    err = g.DB().Table("order").Where("id", id).Struct(&order)
+    if err != nil && err == sql.ErrNoRows {
+        err = nil
+    }
+    return
+}
+```

+1. gform对于MySQL字段类型为datetime类型的时区问题分析；
+1. 改进证书打开失败时的WebServer错误提示，前置HOOK校验后关闭后续的HOOK逻辑执行；
+1. 目前WebServer的HOOK是按照优先级执行的，需要增加覆盖特性；
+1. 更新跨域请求CORS相关功能文档；
+1. ghttp.Response增加输出内容后自动退出当前请求机制，不需要用户手动return，参考beego如何实现；
+1. gcfg包目前允许添加重复的目录路径，需要在SetPath/AddPath时判断重复性，不能添加重复的路径；
+1. gdb执行数据写入时，如果参数为struct/[]struct，自动映射与表字段对应关系，不再使用gconv标签标识；
+1. gdb的Data方法支持struct参数传入；
+1. gfcache依旧使用gcache作为缓存控制对象，不要使用gmap；
+1. 增加对ghttp路由注册的{.struct}/{.method}单元测试；
+1. gconv针对struct的转换增加json tag支持，gconv.Map默认也支持json tag, 完善开发文档；
+1. 增加SO_REUSEPORT的支持；
+1. gkafka这个包比较重，未来从框架中剥离出来；
+1. str_ireplace: http://php.net/manual/en/function.str-ireplace.php
+1. strpos/stripos/strrpos/strripos: http://php.net/manual/en/function.stripos.php
+1. gfile对于文件的读写强行使用了gfpool，在某些场景下不合适，需要考虑剥离开，并为开发者提供单独的指针池文件操作特性；
+1. ghttp.Client自动Close机制；
+1. ghttp路由功能增加分组路由特性；
+1. 增加可选择性的orm tag特性，用以数据表记录与struct对象转换的键名属性映射；
+1. gview中的template标签失效问题；

-// Package gqueue provides a dynamic/static concurrent-safe(alternative) queue.

-// 2、动态的队列大小(不限大小)；
-// 3、取数据时如果队列为空那么会阻塞等待；
+// Package gqueue provides a dynamic/static concurrent-safe queue.
+//
+// Features:

+// 1. FIFO queue(data -> list -> chan);
+//
+// 2. Fast creation and initialization;
+//
+// 3. Support dynamic queue size(unlimited queue size);
+//
+// 4. Blocking when reading data from queue;
