Garbage collection algorithm　　1. tag cleanup algorithm: First mark the objects to be reclaimed, and then collect them. Cons: 1. The efficiency of labeling and purging is not high. 2. Generate a lot of memory fragmentation.2. Replication algorithm: Divided into eden:survivor from:survivor to = 8:1:1 (Cenozoic ratio) CenozoicEden and from are used to preserv

If master hangs, you can immediately enable Slave1 to do master, other unchanged. (a) Redis

unmanaged resources, such as connection handles. Now that the managed and unmanaged resources are clear, the following formally describes the use of the IDisposable interface. objects created in C #, arrays, lists ... There is no need to consider the issue of resource deallocation because it is automatically reclaimed by the CLR's garbage collection mechanism. For example, there is a objectbase class that creates this object and then empties it, which is automatically reclaimed after a perio

The Java language does not have the same syntax to manipulate memory directly as C + +, and the Java language does not provide the syntax for direct manipulation of memory, but programs require memory space to support the Java language, which typically has two methods of memory application: One is static memory allocation and the other is dynamic memory allocation (malloc). 1. Static memory allocation and recycling Java static memory allocation is whe

Gitlab basic Operations-upload, download, library migration/backup and recycling/renaming Gitlab Basic ConceptsGitlab is a Web-based Git repository management tool with wiki and issue tracking capabilities. GitLab is developed by GITLAB Inc. to use open source licenses.GitLab was developed by Ukrainian programmers Dmitriy Zaporozhets and Valery Sizov. It is written by Ruby. Later, some parts were rewritten in the go language. As of December 2016,

In Java, its memory management consists of two aspects: memory allocation (when creating Java objects) and memory recycling, both of which are done automatically by the JVM, which reduces the learning difficulty of Java programmers and avoids the danger of direct manipulation of memory like C + + +. However, because memory management is entirely the responsibility of the JVM, many programmers in Java are no longer concerned with memory allocation, cau

Overview After reading the memory compression, and recently looking at memory recycling this block of code, found that there are a lot of content, need to be divided into several pieces to elaborate, first of all, to say the reverse mapping of anonymous pages, anonymous pages mainly for the process address space heap, stack, as well as private anonymous shared memory (for the process of kinship), The linear areas to which these anonymous pages belong

simple!However, the code above has a bug, and if there are many child processes exiting at the same time, the parent process will be sent a signal.And we know that due to the constraints of the bitmap, the conventional signal appears multiple times, only one time. Therefore, if there is a child process at the same time, the above code must not be all the child processes are recycled!So, we need to strengthen the code!!!!Upgrade Core Codevoid waitChild2 (int sig) {int status = 0;pid_t PID = 0;wh

) each time a 1 Revisedobjectinheap object is created, but it consumes 2M of out-of-heap memory. Such a heap of memory is sufficient (in which case garbage collection of heap memory is not performed), but the out-of-heap memory is insufficient, so OutOfMemoryError is not reported . Although the improved REVISEDOBJECTINHEAP does not have an out-of-heap memory leak, this workaround wastes heap memory unnecessarily. A simple look at the next Bytebuffer source, its internal allocation of external me

object can be associated with another thread). If the queue is created successfully, the queue is entered, and the failure (queue number greater than maxdelayedqueues) discards the object (freed by the JVM Recycle) Note: 1) The object is reclaimed by the weakorderqueue of the local thread, The reason for doing this is to avoid concurrency (races competition), and not every object has an object recycle pool to reclaim, if exceeding the maximum capacity limit is discarded, and the local thread st

MINORGCThe second step there is a risk, if the guarantee fails, it will be a FULLGC, so the cost is greater, because the prevention work is not done well, MINORGC can not finish the ride to a full. In the old age, because there may be 100% survival, so the replication algorithm will lead to insufficient space, the general use of tag-collation algorithm. The JVM generally uses the method of generational collection. garbage collector: There are serial parallel collectors and many other 2. Memory
