why and how to use FindBugsThe static analysis tool promises to find bugs that are already in the code without the hassle of a developer. Of course, if you have many years of experience in writing, you will know that these commitments are n
YII source code analysis (-) and yii source code analysis
As the first show of source code analysis, I chose yii (reading as an example, not as an example). I won't say much about its praise, but I will go straight into the topic.
What is BEAM?
A statement about the abbreviation BEAM
In the purpose of brevity, this article uses the abbreviation-beam of the tool name, which is simply the acronym for the tool's "Checking Tool for Bugs Errors and mistakes", rather than the name of the tool.
IBM Checking Tool for Bugs Errors and mistakes (with its initials BEAM later in this article) is a static analysis tool developed by IBM that can
0x00 PrefaceThe static disassembly King, without a doubt, IDA Pro, greatly reduces the threshold for disassembly, especially the excellent "F5 plug-in" Hex-rays can restore the assembly code to a C-like pseudo code, greatly improving readability. But personally feel that "F5 plug-in" can only be used as an auxiliary means, after the combination of dynamic debuggi
each field, it starts with writefieldbegin. The writing segment type and the sequence number of the field. If the field is a struct class, you can call this class's own encoding method write (tprotocol ). Thrift generates classes for each struct, which define the encoding and decoding methods of this class. End with writestructend.
2. the decoding method starts from readstructbegbegin, reads the field metadata readfieldbegin, reads the field type of 1 byte, And the byte sequence number of 2 fie

red/black tree is better than that of the AVL Tree. Of course, the AVL tree may be more efficient in query, but it is actually not much higher.
The insert/delete operation of the red/black tree is simple, that is, the insert/delete operation of the binary sorting tree. The red and black trees are considered abnormal because they are inserted and deleted to adjust the red and black trees (rotation and coloring). There are many situations, due to the limited length and familiarity of bloggers, we

HMaster startup code analysis for source code analysis of HBase1.0.0 (2), hbase1.0.0hmaster
In the previous blog, my code analysis is the startup function of the startMaster core. This article mainly analyzes the corresponding com
One, synchronized synchronous statement block:
Before introducing the synchronization statement block, do an experiment to verify that the order in which multiple threads call the same synchronization method is random.
Example one:
1) Mylist.java
2) Test:
It is visible that the code in the synchronization method is printed synchronously, but thread A and thread B are executed asynchronously, which may cause dirty reads. Look at the following example
