在 macOS 上查看并解析 electron crash
在开发 electron 应用时，有时会遇到 crash 的情况，但是由于因为某些原因，应用可能没有接入 sentry 或者其他 crash 分析平台，这时候就需要手动查看 crash 日志来定位问题。
寻找本地 crash 日志
因为 electron 本身是基于 chromium 的，所以在 crash 相关的操作也基本和 chromium 一致。
在 chromium crash-reports 中，我们可以看到 crash 文件被保留在 ~/Library/Application\ Support/Chromium/Crashpad/completed 目录下。但是由于我们是 electron 应用，没有“提交”这个过程，所以 crash 文件会被保留在 ~/Library/Application\ Support/Chromium/Crashpad/pending 目录下。
在查找前，记得把上面的目录中的 Chromium 替换为你的应用名，比如 OOMOL Studio。
如果你 crash 的次数比较多，那么你会在这个目录下看到很多的 *.dmp 文件，一般而言，我们需要分析的都是最近一次 crash 的，所以最新的文件就是我们需要的。
解析 crash 文件
使用 breakpad
breakpad 是一个 Google 开源的 crash 分析工具，也是专门为 chromium 开发的。我们可以使用这个工具去解析我们的 dmp 文件。
git clone https://chromium.googlesource.com/breakpad/breakpad
cd breakpad
./configure
make
# 可选
make install执行上面的命令后，你可以通过 ./src/processor/minidump_stackwalk 来解析 dmp，也可以直接使用 minidump_stackwalk (如果你执行了 make install 的话)
基本的使用方法是:
minidump_stackwalk /path/to/your.dmp [/path/to/symbols]如果你直接使用 minidump_stackwalk /path/to/your.dmp 那么你得到的输出也都是地址，无法看到函数名。所以我们需要提供符号文件，这样才能看到函数名。
你可以通过: wget https://github.com/electron/electron/releases/download/<ELECTEON_VERSION>/electron-<ELECTEON_VERSION>-darwin-arm64-symbols.zip 来下载符号文件，以我自己为例，我下载的是:
wget https://github.com/electron/electron/releases/download/v30.5.1/electron-v30.5.1-darwin-arm64-symbols.zip这个文件是专门为 breakpad 准备的，所以我们可以直接解压到某个目录下，然后使用这个目录作为参数传递给 minidump_stackwalk。
minidump_stackwalk ./0c6d2547-6694-4109-b82e-cc3e6331885f.dmp ./electron-v30.5.1-darwin-arm64-symbols/breakpad_symbols接下来你就可以看到详细的 crash 信息了。在我例子中，我得到的结果是:

...可以看到，这里 crash 的原因是: Helper (Plugin) 进程(这个对应了 electron 中的 AppName Helper (Plugin).app) 在使用 UtilityMain(对应了 electron 中的 utilityProcess) 时，v8 申请内存失败，导致 crash。
结合我们的业务需求就是: 我们在使用 electron 的 utilityProcess.fork 方法时，由于被 fork 的脚本中的 v8 引擎无法申请到内存，导致 crash。
最终发现是因为我们在做代码签名时，对 AppName Helper (Plugin).app 声明的 entitlements 缺少了 com.apple.security.cs.allow-jit 权限所导致的。
使用 lldb
就我个人而言，我会更喜欢使用 lldb 来查看 crash 的原因，因为 lldb 的输出更加直观一些。
首先通过下面的命令来下载 dsym 文件:
wget https://github.com/electron/electron/releases/download/v30.5.1/electron-v30.5.1-darwin-arm64-dsym.zip解压完成后，我们需要设置 lldb 的搜索路径并执行 bt 来查看:
lldb -c ./0c6d2547-6694-4109-b82e-cc3e6331885f.dmp -o "settings set target.exec-search-paths ./electron-v30.5.1-darwin-arm64-dsym" -o "bt"最终得到的输出如下:
