多线程上传多个mp4 崩溃 std::map find #90

Open yondu202 opened 3 years ago

yondu202 commented 3 years ago

SDK 外部使用多线程上传多个 mp4 文件，有一定概率崩溃，崩溃在 std::map find 中

1、SDK 版本 1.9.0； 2、VS2013 3、每个线程一个 OssClient 4、调用栈信息 STACK_TEXT:

写了个测试代码，在 2013上没有复现 这个问题。 static void runSingleTask() { ClientConfiguration conf; auto client = new OssClient("endpoint", "accessKeyId", "accessKeySecret", conf); while (true) { auto request = InitiateMultipartUploadRequest("test-bucket-name", "test.mp4"); auto outcome = client->InitiateMultipartUpload(request); if (outcome.isSuccess()) { client->AbortMultipartUpload(AbortMultipartUploadRequest("test-bucket", "test.mp4",outcome.result().UploadId())); } //std::this_thread::sleep_for(std::chrono::microseconds(100)); } }

{ ... std::vector<std::future> taskVec; for (int i = 0; i < 10; i++) { auto task = std::async(std::launch::async, runSingleTask); taskVec.emplace_back(std::move(task)); }

for (int i = 0; i < 10; i++) {
    taskVec[i].get();
}
...

}

能否在你的环境上帮忙做个测试： 把 aliyun-oss-cpp-sdk/sdk/src/utils/Utils.cc::LookupMimeType 里的 mimeType 移到函数外定义？

类似如下： const static std::map<std::string, std::string> mimeType = { ... }; const std::string& AlibabaCloud::OSS::LookupMimeType(const std::string &name) { const static std::string defaultType("application/octet-stream"); ... }
