The object is dead! The first thing to do before the garbage collector recycles the heap is to determine which of these objects is "alive" . which are already "dead" (that is, the object that can no longer be used by any means). 1) Reference counting algorithm Add a reference counter to each object, and whenever there is a place to reference it, The counter value is plus l ; when the reference fail

Sometimes you like your books. -- Feng Tang 1. The dead-lock event occurs in sqlserver, mainly because two threads occupy the exclusive lock of a resource respectively, and then the two threads obtain the exclusive lock of the resources owned by the other side. This causes dead-lock. 2. when encounters dead-lock, it selects one thread from two threads as the win

few days writing a control in MFC, and people completed it in minutes in C. Does MFC really make stinky tofu? I guess it's time for me to switch? As a result, I searched Google and Baidu for the following keywords: "still using MFC" "MFC dead" "MFC dead" ...... This is true. In the search results, most of the posts are from. That is to say, many people thought that MFC was not going to work in. Over the p

int main () { int i; int a[5]; for (i = 0; I A variable is passed in as a function parameter, but after the function call is finished , the value of the variable has changed, do not know why. It turns out that there is an address cross-border problem in the function, which causes the value of the variable to be changed, a bit incredible! For example, the following program, because the array subscript out of bounds causes a dead loop:orig

When I put forward the idea of "the Internet is dead", many people will be puzzled. But no matter what they think, the Internet is really dead. Each new technology, mechanical or intellectual property breakthrough has its own "good time", perhaps a few days, months, or years. But their "good times" do not always exist, and that is the truth. Each generation has its own definition of breakthroughs. Cars, tel

In recent days, the school's MySQL database has always been a lot of dead connections, mainly because there are too many sleep connections, and time is very long, full of all the number of available connections, so that other users can no longer connect to the database. I started to think about tuning MySQL database parameters, but changing many of the parameters still didn't solve the problem. So think of a more ruthless way, write a PHP script, ever

for an object is to expect to receive a system notification when the object is reclaimed by the collector. After JDK1.2, a phantomreference is provided to implement the virtual reference.Objects that are unreachable in the root search algorithm are not "dead", and they are temporarily in the "probation" stage to actually declare an object to die, at least two times to go through the tagging process: If the object finds no reference chain connected to
