Recently read the Linux heap management article, this blog post is to refine and summarize the article.Getting started binary is hard!Linux Heap management strategy1. General statementWhen malloc is called in the main thread, it is discovered that the system allocates a heap to the program and is exactly above the data segment. This means that it is implemented through the BRK system call. and the allocated address space is much larger than the size of the request, we call it the main

, otherwise it assumes that only a single object is to be deleted. If the programmer does not provide the necessary brackets, then only the first element will be refactored. Other elements still exist-although their associated memory has been asked to be returned.The execution of the destructor on the array, as we can see, is based on the "destructor of the removed pointer type" given to the Vec_delete () function. This is obviously not what we want. In addition, the size of each element is also

"DOTA 2" was released free of charge, released on July 9, 2013 in Windows, released on the Linux version on July 18, 2013, and can o

It mainly determines the following information. (1) The size of a Arena is KB (it is used to manage the pool) (2) The size of a pool is 4 kb. Now let's take a look at the definition of the more imp

With the gradual evolution of the network, the surge in the number of users puts pressure on the network. The first problem to be solved is the shortage of Address resources. Now we have proposed the deployment of the IPv6 network environment, but the excessive problem is still the key to our solution. Now let's take a look at this issue. To cope with this crisis, IPv6 technology is widely regarded as the most effective solution ｡ Protocol conversion is required to enable multicast communication

The current network IP resources cannot last long. Many experts predict that IPv4 addresses will be exhausted in the near future. To cope with this crisis, we generally think that the most effective solution is to apply IPv6 technology to the Internet. What new feelings can this IPv network environment give us? Protocol conversion is required to enable multicast communication between an IPv4 host and an IPv6 host) the technical solution can achieve intercommunication between IPv4 and IPv6 networ

This is another impasse. Are there other factors that cause query buffer resize to slow down? We crawl Pstack again. But at this time, jemalloc aroused our attention. Recall the memory allocation mechanism of REDIS, R

. New versions of glibc present in RHEL6 include a new arena allocator design. In several clusters we've seen this new allocator cause huge amounts of the virtual memory to being used, since when multiple thrEADS perform allocations, they each get their own memory arena. On a 64-bit system, these arenas was 64M mappings, and the maximum number of arenas is 8 times the number of CORES
