Qt Windows CMakeLists.txt 注意事项

改为32位GUI启动

默认会出现命令行黑窗口，需要添加图形界面类型

if(WIN32)
    set(GUI_TYPE WIN32)
elseif(APPLE)
    set(GUI_TYPE MACOSX_BUNDLE)
endif()

add_executable(${CMAKE_PROJECT_NAME} ${GUI_TYPE} ${SRC} ${RES})

为QT应用添加管理员权限

set_target_properties(${PROJECT_NAME} PROPERTIES LINK_FLAGS "/MANIFESTUAC:\"level='requireAdministrator' uiAccess='false'\"")

解决复制dll错误问题

第一次复制成功后，注释以下代码

    foreach (QT_LIB ${REQUIRED_LIBS})
        add_custom_command(TARGET ${PROJECT_NAME} POST_BUILD
                COMMAND ${CMAKE_COMMAND} -E copy
                "${QT_INSTALL_PATH}/bin/Qt${QT_VERSION}${QT_LIB}${DEBUG_SUFFIX}.dll"
                "$<TARGET_FILE_DIR:${PROJECT_NAME}>")
    endforeach (QT_LIB)

设置`CMAKE_PREFIX_PATH`路径

set(CMAKE_PREFIX_PATH "D:\\Qt\\Qt5.12.9\\5.12.9\\msvc2017\\")

使用ab,siege,jmeter进行快速JSON API性能测试

发表评论

ab

ab -c 10 -n 100 -T 'application/json' -p test.json https://abc.com/test

siege

siege -c50 -t60S --content-type "application/json" 'http://domain.com/path/ POST {"ids": ["1","2","3"]}'

Jmeter

下载安装jmeter后，运行bin目录下的jmeterw.cmd即可。

待研究 plow

https://github.com/six-ddc/plow

跨平台，无运行时依赖（基于 golang ）
高性能，比常见的 hey，ab，siege 等性能高不少（基本和 wrk 持平）
终端实时展示性能数据，包括 RPS，延迟统计，百分位，Histogram 分布等
支持实时网页展示，更全方面展示各时间点的压测数据

待研究 wrk

https://github.com/wg/wrk

Wrk 是一个现代的 HTTP 基准测试工具，能够在单个多核 CPU 上运行时产生大量负载。它将多线程设计与可伸缩的事件通知系统(如 epoll 和 kqueue)结合在一起。

可以使用lua脚本生成测试请求

How to use PowerShell as default terminal in IntelliJ/PhpStorm/Pycharm/…

Open IntelliJ settings.
Go to the “Tools” section.
Press the “Terminal” option.
Set the correct Shell path to the PowerShell EXE file. In the case of Windows 8.1, the path is: C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe. You should use the latest PowerShell version available!
Create a new terminal session in IntelliJ. Alternatively, you can just restart IntelliJ to apply the changes.

C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe

Setup JetBrains(InteliJ, WebStorm, PHPStorm) IDE terminal to use GIT bash

File
Settings
(Enter ‘Terminal’ in search)

Change Shell path to:

"C:\Program Files\Git\bin\sh.exe" --login -i

git对于不同仓库使用不同的ssh key

发表评论

配置 core.sshCommand:

从 Git 版本 2.10.0 开始, 可以通过这个配置配置全局或者个别仓库使用的key了

git config core.sshCommand "ssh -i ~/.ssh/id_rsa_example -F /dev/null"
git pull
git push

使用MailCatcher作为开发环境邮件服务器

发表评论

MailCatcher 运行一个超级简单的 SMTP 服务器，它可以捕获发送到它的任何消息并在 web 界面中显示。

运行 mailcatcher，将你最喜欢的应用程序设置为 smtp://127.0.0.1:1025，而不是默认的 SMTP 服务器，然后检查 http://127.0.0.1:1080，查看到目前为止的邮件。

file

ubuntu安装MailCatcher

sudo apt install ruby ruby-dev libsqlite3-dev build-essential
sudo gem install mailcatcher

运行

默认运行即可，更多参数如下

mailcatcher -h
Usage: mailcatcher [options]
        --ip IP                      Set the ip address of both servers
        --smtp-ip IP                 Set the ip address of the smtp server
        --smtp-port PORT             Set the port of the smtp server
        --http-ip IP                 Set the ip address of the http server
        --http-port PORT             Set the port address of the http server
        --http-path PATH             Add a prefix to all HTTP paths
        --no-quit                    Don't allow quitting the process
    -f, --foreground                 Run in the foreground
    -v, --verbose                    Be more verbose

Cmder + Windows Terminal + PhpStrom/PyCharm/IDEA

发表评论

Cmder是一个可用于linux的便携式控制台虚拟器，可以让你在windows下使用linux命令。

Windows Terminal是Windows 10的控制台管理界面。

IDEA是广大开发人员的最爱。

本文介绍如何将Cmder整合到Windows Terminal和IDEA。

file

安装Cmder

可以去 https://cmder.net/ 下载最新的压缩文件，解压后点击Cmder.exe即可使用。如果已经安装了git for windows下载mini版本就可以了，否则可以下载包含git的full版本。

设置系统环境变量

以下d:\tools\Cmder是Cmder解压目录

CMDER_ROOT = d:\tools\Cmder

配置 Windows Terminal

生成guid

进入Power shell，输入New-Guid

PS C:\Users\Administrator> New-Guid

Guid
----
092f8948-9ea5-4928-bea7-a1f71938e717

修改 Windows Terminal 配置文件

点击Windows Terminal的下拉菜单，选择“配置”，会打开它的配置文件

增加

{
  "guid": "{092f8948-9ea5-4928-bea7-a1f71938e717}",
  "name": "Cmder",
  "commandline": "cmd.exe /k %CMDER_ROOT%\\vendor\\init.bat",
  "startingDirectory": "%USERPROFILE%",
  "icon": "%CMDER_ROOT%\\icons\\cmder.ico",
  "background": "#2e3436",
  "padding": "15",
  "fontFace": "Cascadia Code",
  "fontSize": 10
}

然后修改

"defaultProfile": "Cmder",

Windows Terminal 使用效果

点击Windows Terminal的加号，查看效果

file

配置 PhpStorm/IDEA/PyCharm

配置 PhpStorm

打开 PhpStrom 的设置，找到 Tools 下的 terminal 修改 Shell path 为 "cmd" /k ""%CMDER_ROOT%\vendor\init.bat""

NSIS实现安装前先停止并卸载旧版

以下脚本会先找到正在运行的程序和服务，停止并删除服务，然后杀掉正在运行的程序进程

    ;检查服务是否存在
    SimpleSC::ExistsService  "${SVCHOST_EXE_NAME}"
    Pop $0
    ;停止并删除服务
    ${If} $0 == 0
        DetailPrint "停止正在运行的打印服务"
        SimpleSC::StopService "${SVCHOST_EXE_NAME}" 1 30
        DetailPrint "删除已安装的打印服务"
        SimpleSC::RemoveService "${SVCHOST_EXE_NAME}"
    ${EndIf}
    ;检查主程序是否运行，如果正在运行则进行终止
    nsProcess::_FindProcess "${ANALYST_EXE_NAME}"
    Pop $R0

JSON、BSON及Protocol Buffer比较

发表评论

他们核心区别在于，bson在json基础上增加了数据日期、文档类型，并支持二进制传输；而protocol buffer则对传输数据和结构定义进行了分离。一般来说与浏览器通信通常使用json，如果需要跨语言通信，且考虑效率，则可以采用protocol buffer。

JSON

特点：

文本存储和传输，结构与数据一体，肉眼可识别

优点：

通用性好，各种语言都支持；
可用于存储

缺点：

采用文本传输，占用体积大，传输性能差
序列化，反序列化性能较差
不支持二进制，日期等数据类型

Bson

特点：

采用二进制传输，结构与数据一体

优点：

在json基础上增加二进制和日期等格式；
传输性能较好
序列化，反序列化性能较好

缺点：

多语言支持一般
传输数据与结构定义仍然在一体

Protocol Buffer

特点：

结构定义与传输数据分离，只传输二进制数据

优点：

用protoc工具可以根据proto文件生成各种语言对应代码
字段被编号，新添加的字段不影响老结构，解决了向后兼容问题。
二进制无结构消息，效率高，性能高。

缺点：

二进制格式，可读性差（抓包dump后的数据很难看懂）
默认不具备动态特性

NSIS打包比较配置文件手动编辑起来非常麻烦，使用HM NIS EDIT向导的话就容易多了。
