Internet of Things application online compiling method based on multi-user cache

Abstract

The invention discloses an Internet of Things application online compiling method based on multi-user cache. The method comprises the steps that a developer writes an Internet of Things application code at a client and uploads the code to a compiling server; and the server compiles each source file in the application code; before compiling, firstly, a hash value of a file is calculated, and a target file corresponding to the hash value is searched in a database; if the target file exists, the file is copied to the current directory, and the next file is compiled; otherwise, the current file iscompiled, and the compiled file is stored into a memory, so that the target file can be reused in the subsequent compiling process. And after all the source files are compiled, a compiled result is returned to the client to finish compiling.

Description

technical field [0001] The invention relates to an online compiling method for Internet of Things applications based on multi-user caching. Background technique [0002] With the development of IoT technology, a large number of IoT devices have emerged. It is predicted that by 2020, there will be 50 billion IoT devices in the world. With the increase of IoT devices, the scale and complexity of IoT applications are also increasing. At present, the traditional IoT application development method requires developers to install the development board driver and the corresponding development environment locally, and the application compilation process is executed locally. There are two main problems in this method: First, IoT devices are highly heterogeneous, and there are many types of development boards, such as ESP32-DevKitC, STM32 Nucleo, Arduino Mega, etc. For developers, using different development boards requires installation and configuration of corresponding device driv...

Problems solved by technology

There are two main problems in this method: one is that IoT devices are highly heterogeneous, and there are many types of development boards, such as ESP32-DevKitC, STM32 Nucleo, Arduino Mega, etc.

However, the above-mentioned tools mainly have the following two defects: First, the types of supported devices are limited. Taking Arduino Web Editor as an example, at present, it only supports Arduino series devices, and other types of devices, such as ESP32-DevKitC, STM32 Nucleo, etc. cannot Using Arduino Web Editor for development leads to poor system compatibility; second, this type of online compiler does not optimize the speed for multi-user online compilation

At present, the online compilation system generally compiles the project files of each user separately. Each compilation needs to recompile all the files of the entire project, and the intermediate compilation results of multiple users cannot be used, resulting in a long compilation time. poor user experience
