OpenHarmony-2.0-Canary

2.0版本的編譯發(fā)生了很大的變化，由hb命令，變成了build.sh。經(jīng)過(guò)分析發(fā)現(xiàn)，build.sh也是調(diào)用各種的python腳本來(lái)進(jìn)行構(gòu)建。這樣看來(lái)1.1.0用json寫配置，用python的 hb 解析，再調(diào)用gn、ninja來(lái)執(zhí)行編譯構(gòu)建反而更簡(jiǎn)單了。估計(jì)下個(gè)版本還會(huì)改，我估計(jì)會(huì)統(tǒng)一成hb命令。

所以這次先簡(jiǎn)單分析下。

  1. -x      #回顯參數(shù)和命令 
  2. -v      #回顯執(zhí)行的源碼 
  3. 打開(kāi) OpenHarmony\build\build_scripts 下的 build.sh、build_common.sh、build_ohos.sh、build_standard.sh、parse_params.sh 
  4. 將set -e 改為 set -exv 開(kāi)啟調(diào)試模式 

build.sh

加了調(diào)試參數(shù)，我們來(lái)分析下 build.sh 在編譯構(gòu)建中做了什么。

  1. # 各種判斷和獲取參數(shù) 
  2.  
  3. # preloader 一.預(yù)加載 
  4. ${PYTHON3} ${source_root_dir}/build/loader/preloader/preloader.py \ 
  5.   --product-name ${product_name} \ 
  6.   --source-root-dir ${source_root_dir} \ 
  7.   --products-config-dir "productdefine/common/products" \ 
  8.   --preloader-output-root-dir "out/build_configs" 
  9.    
  10. # 設(shè)置環(huán)境變量 
  11. source ${source_root_dir}/out/build_configs/${product_name}/preloader/build.prop 
  12. # source /home/bright/OpenHarmony/out/build_configs/Hi3516DV300/preloader/build.prop 
  13.  
  14. # call build 二.編譯構(gòu)建 
  15. ${source_root_dir}/build/build_scripts/build_${system_type}.sh \ 
  16.   --product-name ${product_name} \ 
  17.   --device-name ${device_name} \ 
  18.   --target-os ${target_os} \ 
  19.   --target-cpu ${target_cpu} \ 
  20.   ${build_params} 

一、預(yù)加載

debug的方法，用單步調(diào)試來(lái)看看這個(gè) preloader.py 的作用。

調(diào)試參數(shù)：

  1. { 
  2.     // 使用 IntelliSense 了解相關(guān)屬性。  
  3.     // 懸停以查看現(xiàn)有屬性的描述。 
  4.     // 欲了解更多信息，請(qǐng)?jiān)L問(wèn): https://go.microsoft.com/fwlink/?linkid=830387 
  5.     "version": "0.2.0", 
  6.     "configurations": [ 
  7.         { 
  8.             "name": "preloader.py", 
  9.             "type": "python", 
  10.             "request": "launch", 
  11.             "program": "./build/loader/preloader/preloader.py", 
  12.             "console": "integratedTerminal", 
  13.             "args": [ 
  14.                 "--product-name","Hi3516DV300", 
  15.                 "--source-root-dir","", 
  16.                 "--products-config-dir","productdefine/common/products", 
  17.                 "--preloader-output-root-dir","out/build_configs" 
  18.             ], 
  19.             "stopOnEntry": true 
  20.         } 
  21.     ] 
  22. } 

調(diào)用了2個(gè)python文件，Z:\OpenHarmony\build\loader\preloader\preloader.py 和 Z:\OpenHarmony\build\scripts\util\file_utils.py

這個(gè)函數(shù)有4個(gè)參數(shù)。

  1. python3 build/loader/preloader/preloader.py \ 
  2.     --product-name Hi3516DV300 \ 
  3.     --source-root-dir "" \ 
  4.     --products-config-dir productdefine/common/products \ 
  5.     --preloader-output-root-dir out/build_configs 
  6.  
  7. Z:\OpenHarmony\build\loader\preloader\preloader.py:180 
  8. # 建議斷點(diǎn)打在這，跳過(guò)import 
  9. parser = argparse.ArgumentParser() 

全部操作主要就是def _run(args):這一個(gè)函數(shù)

  1. Z:\OpenHarmony\build\loader\preloader\preloader.py:133 
  2. def _run(args): 
  3.     # 忽略不重要的步驟，直接看核心部分 
  4.      
  5.     # 生成 out/build_configs/Hi3516DV300/preloader/parts.json 
  6.     write_json_file(parts_info_file, parts_config_info) 
  7.  
  8.     # 獲取 OpenHarmony/build/loader/preloader/platforms.template 這個(gè)模板 
  9.     platforms_template_file = _get_platform_template_file(args.source_root_dir) 
  10.      
  11.     # 復(fù)制 OpenHarmony\out\build_configs\standard_system\platforms.build 
  12.     _copy_platforms_config(platforms_template_file, parts_info_file, 
  13.                            platform_config_output_path) 
  14.  
  15.     _build_info_list = [] 
  16.     build_info_file = os.path.join(product_info_output_path, 'build.prop') 
  17.     for k, v in build_configs.items(): 
  18.         _build_info_list.append('{}={}'.format(k, v)) 
  19.      
  20.     # 生成 out/build_configs/Hi3516DV300/preloader/build.prop 
  21.     write_file(build_info_file, '\n'.join(_build_info_list)) 

簡(jiǎn)單來(lái)說(shuō)就是通過(guò)產(chǎn)品形態(tài)配置倉(cāng)調(diào)取3個(gè)json文件+1個(gè)platforms.template，生成3個(gè)配置文件

產(chǎn)品形態(tài)配置倉(cāng)調(diào)取3個(gè)json文件，具體可以參考：https://gitee.com/openharmony/productdefine_common

配置文件：

  1. 配置文件： 
  2. productdefine/common 
  3. ├── base                         # 不同系統(tǒng)類型的最小系統(tǒng)，開(kāi)發(fā)者不用配置，系統(tǒng)提供 
  4. │   └── standard_system.json 
  5. ├── device                       # device配置，配置文件按照device name命名 
  6. │   └── hi3516dv300.json 
  7. └── products                     # 產(chǎn)品配置，配置文件按照product name命名 
  8.     └── Hi3516DV300.json 
  9.  
  10. 輸出文件： 
  11. ├── Hi3516DV300 
  12. │   └── preloader 
  13. │       ├── build.prop 
  14. │       └── parts.json 
  15. └── standard_system 
  16.     └── platforms.build 

 來(lái)個(gè)更直觀的對(duì)比圖吧。

二、編譯構(gòu)建 build_standard.sh

這個(gè)腳本有2個(gè)任務(wù)：

準(zhǔn)備好參數(shù)執(zhí)行g(shù)n、ninja構(gòu)建命令。

將編譯好的文件打包成鏡像。

  1. build/build_scripts/build_standard.sh --product-name Hi3516DV300 --device-name hi3516dv300 --target-os ohos --target-cpu arm 
  2. # 換個(gè)姿勢(shì)，方便查看 
  3. build_standard.sh  
  4.     --product-name Hi3516DV300  
  5.     --device-name hi3516dv300  
  6.     --target-os ohos  
  7.     --target-cpu arm 

接下來(lái)先分析下 build_standard.sh

  1. Z:\OpenHarmony\build\build_scripts\build_standard.sh 
  2.  
  3. # 忽略不重要的步驟，直接看核心部分 
  4.  
  5. function main() { 
  6.   # build ohos 
  7.   do_make_ohos  # 這個(gè)函數(shù)在 OpenHarmony\build\build_scripts\build_common.sh 文件中。 
  8.   # 而最終這個(gè)函數(shù)會(huì)生成，下面這條構(gòu)建腳本，主要的編譯工作都是由 build_ohos.sh 來(lái)完成的。 
  9. + build/build_scripts/build_ohos.sh device_type=Hi3516DV300 target_os=ohos target_cpu=arm gn_args=is_standard_system=true   
  10.  
  11.   ... ... 
  12.  
  13.   # build images 
  14.   build/adapter/images/build_image.sh --device-name ${device_name} \ 
  15.     --ohos-build-out-dir ${ohos_build_root_dir}/packages/phone 
  16.   # 第二部分重要工作是生成鏡像。參考：2.【生成鏡像】 
  17. + build/adapter/images/build_image.sh --device-name hi3516dv300 --ohos-build-out-dir /home/bright/OpenHarmony/out/ohos-arm-release/packages/phone 
  18. } 

1.build_ohos.sh【編譯構(gòu)建】

這個(gè)腳本的結(jié)構(gòu)就簡(jiǎn)單了
