[英]How to get crashed process id from a minidump file
我的應用程序是用 Electron(v11.1.1) 開發的,它使用 crashpad 來捕獲來自每個進程的所有崩潰 dmp 文件。 如何從小型轉儲文件中獲取崩潰的進程 ID 或其他元數據
我發現我們可以直接從dmp文件中解析一些字段
async function parseProcessDetailFromDump(dumpPath) {
return new Promise((ok, fail) => {
const readStream = fs.createReadStream(dumpPath)
let ptype = null
let pid = null
readStream.on("data", (chunk) => {
const text = chunk.toString(`utf-8`)
const lines = text.split(path.sep)
for (const line of lines) {
const found = line.match(/ptype/)
if (found != null && found.length > 0) {
const regPtype = /(?<=ptype[^0-9a-zA-Z]+)[0-9a-zA-Z]+/gu
const regPid = /(?<=pid[^0-9a-zA-Z]+)[0-9a-zA-Z]+/gu
ptype = line.match(regPtype)[0]
pid = line.match(regPid)[0]
}
}
})
readStream.on("error" , () => {
rejects()
})
readStream.on("end", () => {
ok({pid, ptype})
})
})
}
