# 1. Goahead开发文档 ## 1.1. Goahead版本 5.2.0 ## 1.2. 编译脚本 ``` # build goahead before make libgo.a add_custom_command( OUTPUT ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/Makefile COMMAND echo "tar zxvf goahead-5.2.0.tar.gz" COMMAND tar zxvf goahead-5.2.0.tar.gz // 解压源码包 WORKING_DIRECTORY ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/ ) add_custom_command( OUTPUT ${EXTERNAL_LIBS_OUTPUT_PATH}/libgo.a DEPENDS ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/Makefile COMMAND make CC=${CMAKE_C_COMPILER} ARCH=${SET_ARCH} PROFILE=${LIB_TYPE} COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libgo.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libgo.a // 拷贝静态库到output目录 COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libmbedtls.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libmbedtls.a // 拷贝静态库到output目录 COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libgoahead-mbedtls.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libgoahead-mbedtls.a // 拷贝静态库到output目录 COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/self.crt ${PLATFORM_PATH}/cmake-shell/ // 拷贝self.crt,self.key两个到运行目录； COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/self.key ${PLATFORM_PATH}/cmake-shell/ // 拷贝self.crt,self.key两个到运行目录； COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/test/route.txt ${GOAHEAD_CONFIG_FILE_PATH} // 配置文件两个：route.txt，auth.txt； COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/test/auth.txt ${GOAHEAD_CONFIG_FILE_PATH} // 配置文件两个：route.txt，auth.txt； WORKING_DIRECTORY ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead ) add_custom_target( libgo.a // 创建goahead目标 DEPENDS ${EXTERNAL_LIBS_OUTPUT_PATH}/libgo.a ) ``` ## 1.3. 环境配置 1. 拷贝self.crt,self.key两个到运行目录； 2. 配置文件两个：route.txt，auth.txt；   self.crt,self.key两个文件默认使用当前路径，需要配置。 详见配置：**GOAHEAD_CONFIG_FILE_PATH** ``` # ------------ build GoAhead ------------ # set(GOAHEAD_DOCUMENTS_PATH "web") set(GOAHEAD_UPLOAD_TMP_PATH "./goahead") set(GOAHEAD_UPLOAD_PATH "${GOAHEAD_UPLOAD_TMP_PATH}") set(GOAHEAD_LIMIT_POST "335544320") # If not defined means using default setting. See goahead-linux-static-fancy.mk # GOAHEAD_CONFIG_FILE_PATH should be set when cross compile set(GOAHEAD_CONFIG_FILE_PATH ".") # ------------ build GoAhead end ------------ # ``` 转换成ME_GOAHEAD_SSL_KEY和ME_GOAHEAD_SSL_CERTIFICATE两个宏来指定文件路径。 ``` add_custom_command( OUTPUT ${EXTERNAL_LIBS_OUTPUT_PATH}/libgo.a DEPENDS ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/Makefile COMMAND make CC=${CMAKE_C_COMPILER} ARCH=${SET_ARCH} PROFILE=${LIB_TYPE} ME_GOAHEAD_UPLOAD_DIR=\"${GOAHEAD_UPLOAD_TMP_PATH}\" ME_GOAHEAD_SSL_KEY=\"${GOAHEAD_CONFIG_FILE_PATH}/self.key\" ME_GOAHEAD_SSL_CERTIFICATE=\"${GOAHEAD_CONFIG_FILE_PATH}/self.crt\" ${ME_GOAHEAD_LIMIT_POST} -f ../modify/goahead-linux-static-fancy.mk COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libgo.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libgo.a COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libmbedtls.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libmbedtls.a COMMAND mv ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/libgoahead-mbedtls.a ${EXTERNAL_LIBS_OUTPUT_PATH}/libgoahead-mbedtls.a COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/self.crt ${PLATFORM_PATH}/cmake-shell/ COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/build/${GOAHEAD_INCLUDE_PATH}/bin/self.key ${PLATFORM_PATH}/cmake-shell/ COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/test/route.txt ${GOAHEAD_CONFIG_FILE_PATH} COMMAND cp ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead/test/auth.txt ${GOAHEAD_CONFIG_FILE_PATH} WORKING_DIRECTORY ${EXTERNAL_SOURCE_PATH}/goahead-5.2.0/GoAhead ) ``` ## 1.4. 代码整改 ### 1.4.1. web服务安全退出   由于官方源码是不超时阻塞，为了方便自动化测试，把官方源码的不超时阻塞改成超时阻塞。 ``` PUBLIC void websServiceEvents(int *finished) { int delay, nextEvent; if (finished) { *finished = 0; } // ===================== added by xiao ===================== // // delay = 0; // open source code #define TIME_OUT_MS 1000 delay = TIME_OUT_MS; // modifed by xiao, time out 1000 ms // ===================== added by xiao end ===================== // while (!finished || !*finished) { if (socketSelect(-1, delay)) { socketProcess(); } #if ME_GOAHEAD_CGI delay = websCgiPoll(); #else delay = MAXINT; #endif nextEvent = websRunEvents(); delay = min(delay, nextEvent); // ===================== added by xiao ===================== // delay = (delay <= 0 || delay >= TIME_OUT_MS) ? TIME_OUT_MS : delay; // ===================== added by xiao end ===================== // } } ``` ### 1.4.2. HTTP POST 文件限制   源码限制POST文件大小太小，这里修改为32M。 ``` ``` ## 1.5. goahead的bug   当goahead使用无效的ip进行listen时，asan工具会报内存泄漏问题，目前暂时忽略该bug ``` ================================================================= ==1420508==ERROR: LeakSanitizer: detected memory leaks Direct leak of 17 byte(s) in 1 object(s) allocated from: #0 0x7f3f4325d808 in __interceptor_malloc ../../../../src/libsanitizer/asan/asan_malloc_linux.cc:144 #1 0x55bc16b87490 in walloc src/alloc.c:280 #2 0x55bc16b991ae in sclone src/runtime.c:2430 #3 0x55bc16b9be26 in socketParseAddress src/socket.c:1334 #4 0x55bc16b891bf in websListen src/http.c:646 #5 0x55bc16b86f59 in WebServerInit /home/xiaojiazhu/project/rkipc/battery/ipc-rk1106/ipc-sdk/utils/WebServer/src/WebServer.cpp:152 #6 0x55bc16b81f4a in AppManager::HttpServerThread(app_param const&) /home/xiaojiazhu/project/rkipc/battery/ipc-rk1106/ipc-sdk/middleware/AppManager/src/AppManager.cpp:79 #7 0x55bc16b829f0 in operator() /home/xiaojiazhu/project/rkipc/battery/ipc-rk1106/ipc-sdk/middleware/AppManager/src/AppManager.cpp:52 #8 0x55bc16b829f0 in __invoke_impl)>, std::shared_ptr > /usr/include/c++/9/bits/invoke.h:60 #9 0x55bc16b829f0 in __invoke)>, std::shared_ptr > /usr/include/c++/9/bits/invoke.h:95 #10 0x55bc16b829f0 in _M_invoke<0, 1> /usr/include/c++/9/thread:244 #11 0x55bc16b829f0 in operator() /usr/include/c++/9/thread:251 #12 0x55bc16b829f0 in _M_run /usr/include/c++/9/thread:195 #13 0x7f3f4301bdf3 (/lib/x86_64-linux-gnu/libstdc++.so.6+0xd6df3) SUMMARY: AddressSanitizer: 17 byte(s) leaked in 1 allocation(s). ```
