The soldiers immediately watched the empty box and tea bricks. At the same time, he said, "the other one is also qui

Chinese, you must set the encoding method. This is also telling our Chinese children that we have to work hard and work hard. In the future, we will develop an awesome software. The default encoding method is the Chinese encoding method. Do you want to use it as a foreigner? If you want to use it, transcode it yourself. Gb2312, GBK, gb18030 are my Chinese encoding (in fact, can also encode Japanese, Korean, etc.), GB2312-80 only receive 6763 Chinese characters, GBK is the extension of the GB23

Look at the wiki today and see a mention of what's going to fall into race condition ABA problem. Ah, I have not heard of Aba Ah, then I went to search for a bit, as follows:Http://www.bubuko.com/infodetail-317006.html"SpinLock spin Lock, CAS operation (Compare Set) ABA problem"The ABA is explained as follows:The so-called ABA (see Wikipedia's ABA Entry), the problem is basically like this: Process P1 reads a value of a in a shared variable P1 was preempted, process P2 executed.

the pointer. If this address is reused, the problem is huge. (address reuse occurs very often, a memory allocation is released, redistributed, most likely the original address)such as the dequeue () function above, because we want to separate head and tail, so we introduced a dummy pointer to head, when we do the CAS, if the head of the memory is recycled and reused, and the memory of Reuse is Enqueue () came in, This is going to be a big problem. ( reusing memory in memory management is basica

may cause some potential problems.The ABA problem is most likely to occur in the lock free algorithm. CAS bears the brunt of this problem because CAS judges the pointer address. If this address is reused, the problem will be very high.(Address reuse often occurs. After a memory is allocated, it is released and distributed. It is likely that the original address is still used) For example, the preceding dequeue () function, because we want to separate head and tail, we introduced a dummy pointer

, using this encoding to encode Chinese is a problem. For programs such as tomcat, the default encoding is iso. to interpret Chinese, you must set the encoding method.
