The last few days decided to look at the CI Framework source code, because it is lightweight, the structure of the code file is clearer, and index.php as a portal, loading all the base classes in the codeigniter.php file, so I looked at each class drop, and looked at the time to analyze each step Key process, and the original English annotation was translated, now the main document has been translated, and
reads a four-byte message header.
Since the NIO server of thrift uses framebuffer as the buffer when reading messages and first reads the 4-byte message header when decoding, it can be inferred that when the client sends messages, the tframedxxxtransport packaging stream is used to transmit data.
Let's take a look at the actual client Object Construction
TSocket socket = new TSocket(host, port); socket.setTimeout(timeout); TTransport transport = new TFramedTr

The operations on events are nothing more than addEvent, fireEvent, and removeEvent. Generally, lib extends the functions provided by the browser to solve problems such as compatibility Memory leakage. The third problem is how to get the domReady status.6.1 event packages
Browser event compatibility is a headache. The IE event is in the global window, while the mozilla event is passed in to the callback function as the event Source parameter. There are also many event handling methods.

helpful to specify a status for the entire workflow instance, which is independent of the Process execution steps. Osworkflow provides "meta-states" that can be included in some workflow instances ". These "meta-states" can be created, activated, suincluded, killed, and completed. When a workflow instance is created, it is in the created state. Then, as long as an action is executed, it will automatically become activated. If the caller does not explicitly change the instance status, the workfl

In the previous article, we completed a single message path from the kernel to the framework consisting of NetlinkManager, NetlinkHandler, NetlinkListener, and SocketListener according to the function call process. Communication is implemented through an internal socket. You can set the filter attribute of the socket listener to receive the event sent by the kernel,(The event part sent by the kernel does not need to be understood. It can be understood as spon
