Sometimes in order to avoid master.info and relay log crashes, the cost of tolerating extra Fsync () is recommended to setSync_master_info = 1Sync_relay_log = 1Sync_relay_log_info = 1Of course, if the standby and the main library latency is particularly large, the standby IO thread thanks a lot of relay logs, through the Relay_log_purge setting, the SQL thread replay the events in a trunk log after the event will be deleted as soon as possible.In extr

In a recent JNI project, the so library was given a layer of JNI encapsulation, equal to the method of invoking a third-party library in the JNI C + + code, and the entire project ran on Android.The third-party library that Libaa.so uses for its own JNI generation is libbb.so.So far, the problem encountered is that libbb a variety of can not find. Where's the LIB

Static library and dynamic library-the path to linux programming-general Linux technology-Linux programming and kernel information. For details, see the following. I am studying Program Design in linux recently and will write my learning experience on the way. I hope you can point out the shortcomings. Linux has two types of function libraries: static library

First, the technical advantages of dynamic link library:1) Save memory and disk space, because a dynamic library can be used by multiple processes or programs in a single copy of memory or disk.2) modular programming for easy collaboration; This static library is also capable.3) when loading DLLs or so dynamically, it is easy to upgrade the module without recompi

24 Useful PHP class libraries to share, 24php class library Currently, PHP is the most popular scripting language for Web development. You can find a lot of information about PHP on the Internet, including documentation, tutorials, tools, and more. PHP is not only a feature-rich language, it also helps developers to easily create better network environments. In order to further help developers, the small series will share with you some free and high-

Dynamic Link Library ConceptsDynamic Library (Abbr,dll) technology is a technique commonly used in programming. Its purpose is to reduce the size of the program, save space, improve efficiency, with high flexibility. Using dynamic library technology makes it easier to upgrade software versions. Unlike a static library,

First, let's take a look at the knowledge about static databases: Program compilation usually requires preprocessing, compilation, compilation, and linking. For some public code in our project, if you want to reuse it, You can compile the code into a static library file. In the link step, the linker obtains the corresponding code from the library file and generates an executable file. The execution file of

Preface: In the previous lesson, we introduced a simple introduction to GCC, including the GCC compilation steps: preprocessing, compilation, assembly, and link. In this lesson, you are welcome to join us in the Linux library.Principle: In Linux, there are two types of libraries: static library and shared library. The static library is. files ending with the suff

1. Static Compilation: when compiling an executable file, the compiler extracts the part of the corresponding dynamic link library (. So or. ilb) that needs to be used and links it to the executable file,Make the executable file do not need to depend on the dynamic link library during running. 2. Dynamic Compilation: a dynamic link library must be attached to the

1, a program compiled from the source file to build the executable file steps:Precompiled--compile-and-link(1) Pre-compilation, that is preprocessing, mainly processing in the source code files with "#" to start the pre-compilation instructions, such as macro expansion, processing conditional compilation instructions, processing # # # directives.(2) The process of compiling is a series of lexical analysis, grammatical analysis, semantic analysis and optimization of the pre-processed files into c

Static Compilation: compile all the DLL and masterProgramAll are compiled into a main program.Dynamic Compilation: the compilation result is that the main program is the main program, and each module is each module.Static compilation and dynamic compilation can be used to set dynamic settings of project properties!Static link: the static link has written the functions in the library into the executable file. That is, the static link puts the required

In the use of STM32 firmware library, you need to add to the project the use of the corresponding source files, such as: STM32F10X_GPIO.C and so on, add a lot of trouble not to say, each time in rebuild to compile these basic unchanged files. and by using the library can solve these problems, first only need to add a library file, the second rebuild only compile

Previously said, if the amount of data to be stored in a database is relatively small, but one table stores more data, such as log table, it is necessary to consider the table storage; But what if the overall storage capacity of a database is relatively large? At this point, we need to consider the library, is to build multiple databases to save data. Here, for example, even if the survey is not many, but the number of people involved in the survey is
