The front information

This machine (MacBook Pro) Electron path: / usr/local/lib/node_modules/Electron/dist/Electron. App/Contents/MacOS/Electron

The machine Electron data file path: / Users/bianchengsanmei/Library/Application Support/Electron

Local path to dump_sysm: /Users/bianchengsanmei/Library/Developer/Xcode/DerivedData/Breakpad-ebqwamwdejfpicartmwratdgdbnc/Build/Products/Release/ dump_syms

Minidumps_stackwalk path/Users/bianchengsanmei/Public/CODE/google_breakpad breakpad/SRC/processor/minidump_stackwalk

Build google_breakpad

  1. downloadgoogle_breakpadThe source code. 
    git clone https://github.com/google/breakpad.git
Copy the code
  2. Compile google_breakpad 
    ./configure && make
Copy the code
  3. Install the built libraries 
    make install
Copy the code

Generate the Electron crash log

// main.js
import { app, crashReporter } from "electron";
import * as path from "path";
crashReporter.start({
    uploadToServer: false
});
app.setPath("crashDumps", process.cwd() + "/crash");
Copy the code

So when the renderer crashes, we can find a dump file in the crash folder of the installation directory. This is the crash log file.

Note that the crashDumps path does not exist in [email protected], but in the temp path.

Parsing dump files

Dump file (hexadecimal data)

To convert this file to a readable, analyzable file, use the tool minidumps_stackwalk in Google_breakpad:

$ /Users/bianchengsanmei/Public/CODE/google_breakpad/breakpad/src/processor/minidump_stackwalk ./crash/test.dump > ./crash/test.info
Copy the code

Open to view test.info:

The Crash reason is the description of the cause of the Crash.
