infinite recovery

situation One:The function appears in an infinite loop in the following two-sentence code:while (ABS (SX-LP.X1) + ABS (SY-LP.Y1) > Lp2.len){SX = (lp.x1 + sx) >> 1;Sy = (lp.y1 + sy) >> 1;}When debugging a breakpoint, the result of an infinite loop is that the value appears as follows:Sx=0x3d00Lp.x1=0x3d01Sy=0x7a00Lp.y1=0x7a01Lp2.len=1in this case, SX and the Sy value is never changed, and the condition of th

PHP Super awesome Infinite Pole classification spanning tree method, PHP Are you still wasting your time and wasting your memory recursively traversing infinite pole categories, reading this article, I think you should change. This is what I saw on the Oschina a very streamlined PHP infinite pole classification Spanning tree method, skillfully in the reference,

Php+mysql implementation of infinite classification examples, mysql instance In this paper, the method of php+mysql realization of infinite classification is described. Share to everyone for your reference. The specific analysis is as follows: 1, the database by setting the parent class ID to make a unique index, and then use the recursive invocation of the function to achieve

In some complex systems, it is required to classify the information columns infinitely, in order to enhance the flexibility of the system. So how does PHP implement an infinite class classification? We use recursive algorithms in this article and combine MySQL data tables to achieve infinite classification.In some complex systems, it is required to classify the information columns infinitely, in order to en

The batch log recovery mode of the SQL Server recovery model. Do you want to know why the transaction log file is getting bigger and bigger? Transaction logs are sometimes larger than your actual database files, especially in the case of application data warehouses. Why is this happening? How to control its size? How does the database recovery model control the g

Eventually:Using CollectionView implementation, with Pagecontrl + timer timer ideas, using 1 groups, but tell the controller has modelarrcount*5000 item, and Cellforrow, Create a modelarrcount based on the index modulo, take out the data source (actually only 8), and the item width is a screen width code snippet:#import "BeyondViewController.h"//Fast Frame#import "uiview+frame.h" #import "BeyondNewsCell.h" #import "BeyondNews.h" # Import "MJExtension.h"//Only one group, but the group has 5000*8

This article mainly introduces php's simple method of implementing an infinite classification tree list. The example analyzes php's skill of implementing tree lists through arrays, which has some reference value. For more information, see This article mainly introduces php's simple method of implementing an infinite classification tree list. The example analyzes php's skill of implementing tree lists throug

Infinite Pole classification: recursive and iterative implementations 1, find the sub-column of the designated column 2, find the descendants of the designated columns, both descendants of the tree 3, find the parent directory of the specified column, grandfather directory 、....,、 top-level directory Raw data to be processed $area =array (Array (' ID ' =>1, ' name ' = ' Shandong ', ' parent ' =>0), array (' ID ' =>2, ' name ' = ' Heze ', ' parent ' =

Back to base: return to base php code for returning list data of infinite classification with array: Copy the code as follows: * ------------------ *-get list data of infinite classes * ------------------ * functionget_sort ($ parent_SELECT * FROM. $ db- gt; table (arti The code is as follows: /*------------------*///-Obtain the list data of an unlimited category/*------------------*/Function get_sort

This article mainly introduces the knowledge of PHP generating infinite column tree. Has a good reference value. Let's take a look at the little series. Column array: $arr =array ( ' cid ' = 2, ' cname ' = ' news ', ' pid ' = 0), Array (' cid ' = 4, ' cname ' = ' sports ', ' pid ' = > 0), Array (' cid ' = 5, ' cname ' = ' entertainment ', ' pid ' = 0), Array (' cid ' = 7, ' cname ' = ' hot News ', ' pid ' =G T;2), Array (' cid ' = 8, ' cname ' =

that the application can run (there are many features do not rely on the external network), at first I thought Dubbo should have the Zkclient connection related timeout configuration, the results have been found for a long time did not find, Later debug Dubbo source code found there is no set timeout, zkclient default timeout time is integer.max_value, almost equal to infinite wait, so helpless under had to rewrite the Dubbo zookeeperclient implement
