nginx源码编译并调试，nginx源码使用GDB或者vscode+GDB远程debug源码调试-图文详细

克隆项目

1
git clone https://github.com/nginx/nginx.git

进入目录下

1
cd /home/hou/nginx

生成配置

1
auto/configure --prefix=./bin --with-debug --with-cc-opt='-O0 -g'

--with-debug

  • 作用：启用 Nginx 的调试日志功能。

  • 解释：

    • 启用后，Nginx 会输出更详细的调试信息到错误日志中（error_log）。

    • 这些信息对于排查问题非常有用，例如请求处理流程、模块加载情况等。

    • 需要在 Nginx 配置文件中设置日志级别为 debug：

      1
      error_log /path/to/error.log debug;
  1. --with-cc-opt='-O0 -g'
  • 作用：向 C 编译器（如 GCC）传递额外的编译选项。
  • 解释：
    • -O0：禁用编译器优化。
      • -O0 表示不进行任何优化，保留所有调试信息，方便调试。
      • 如果使用 -O2 或 -O3，编译器会优化代码，可能会影响调试（例如变量被优化掉，无法查看）。
    • -g：生成调试信息。
      • 在编译时生成调试符号，这些符号会被 GDB 等调试工具使用。
      • 如果没有 -g，GDB 将无法显示源代码和变量信息。

要查看 Docker 容器中的存储卷或挂载点是如何映射到主机的，可以通过以下步骤来检查：

1. 使用 docker inspect 命令

docker inspect 命令可以查看容器的详细配置信息，其中包括挂载的卷（volumes）和绑定挂载（bind mounts）。

具体命令如下：

1
docker inspect <container_name_or_id>

这个命令将返回一个包含容器所有信息的 JSON 文件。你可以从其中找到有关存储挂载的部分。

2. 查找卷和绑定挂载信息

在 docker inspect 返回的结果中，查找以下字段：

  • "Mounts": 列出所有卷和绑定挂载信息。

示例输出：

"Mounts": [
    {
        "Type": "bind",
        "Source": "/host/path",
        "Destination": "/container/path",
        "Mode": "rw",
        "RW": true,
        "Propagation": "rprivate"
    },
    {
        "Type": "volume",
        "Name": "my_volume",
        "Source": "/var/lib/docker/volumes/my_volume/_data",
        "Destination": "/container/volume",
        "Driver": "local",
        "Mode": "rw",
        "RW": true,
        "Propagation": ""
    }
]

在这个例子中：

  • 绑定挂载（bind mount）:
    • 容器内部的 /container/path 挂载到了主机的 /host/path。
  • 卷（volume）:
    • 容器内部的 /container/volume 使用了 Docker 卷 my_volume，存储在主机的 /var/lib/docker/volumes/my_volume/_data 目录下。

3. 过滤查看挂载点

如果你只想查看挂载点信息，可以使用 docker inspect 的 --format 选项来过滤信息。比如只显示挂载点信息：

1
docker inspect --format='{{json .Mounts}}' <container_name_or_id>

这样可以直接输出容器的挂载信息，简化结果。

总结

通过 docker inspect 命令，你可以清楚地看到容器中的存储卷或者挂载的目录对应主机上的哪个路径。

根据时间复杂度的不同，大致分为3类：

  1. 时间复杂度O(n^2)的排序算法: 冒泡，选择，插入，希尔排序
  2. 时间复杂度O(nlogn)的排序算法: 快速，归并，堆排序

# disable-warnings-as-errors选项是禁止把warning 当成error
# --with-debug-level=slowdebug。用来设置编译的级别，可选值为release、fastdebug、slowde-bug，越往后进行的优化措施就越少，带的调试信息就越多。默认值为release。slowdebug 含有最丰富的调试信息，没有这些信息，很多执行可能被优化掉，我们单步执行时，可能看不到一些变量的值。所以最好指定slowdebug 为编译级别。
# with-jvm-variants 编译特定模式的HotSpot虚拟机，可选值：server、client、minimal、core、zero、custom

make命令可以指定参数
-O0 参数表示告诉编译器不要优化代码，防止在 Debug 的时候， IDE Redis 源码 与 实际运行的 对应不上。
MALLOC=jemalloc ，Mac OS 系统Redis默认内存分配器是libc，通过 MALLOC=jemalloc 指定使用 jemalloc 内存分配器

1、将logback_namesrv.xml和logback_broker.xml配置文件中的所有${user.home}都替换为自己的ROCKETMQ_HOME的目录，例如

{user.home}/logs/rocketmqlogs/namesrv_default.log，我会替换为C:/Users/27338/IdeaProjects/rocketmq/config/logs/rocketmqlogs/namesrv_default.log；

2、将所有的${brokerLogDir}都替换为broker
