Crashpad is an open-source multiplatform crash reporting system written in C++ by Google. It supports macOS, Windows and Linux (limited), and features an uploader to submit minidumps to a configured URL right when the process crashes.
This page describes standalone usage of Crashpad with Sentry. We strongly encourage you to use our Native SDK. For detailed information about using Crashpad with the Native SDK, see the Crashpad backend documentation.
Follow the Crashpad developer docs for instructions on how to build Crashpad from source. Make sure that crashpad’s header files are in your include path, then add a call to StartHandler() during your program startup:
#include <map>
#include <string>
#include <vector>
#include "client/crashpad_client.h"
#include "client/settings.h"
using namespace crashpad;
bool startCrashpad() {
// Cache directory that will store crashpad information and minidumps
base::FilePath database("path/to/crashpad/db");
// Path to the out-of-process handler executable
base::FilePath handler("path/to/crashpad_handler");
// URL used to submit minidumps to
std::string url("https://o0.ingest.sentry.io/api/0/minidump/?sentry_key=examplePublicKey");
// Optional annotations passed via --annotations to the handler
std::map<string, string> annotations;
// Optional arguments to pass to the handler
std::vector<string> arguments;
CrashpadClient client;
bool success = client.StartHandler(
handler,
database,
database,
url,
annotations,
arguments,
/* restartable */ true,
/* asynchronous_start */ false
);
return success;
}
This method directs crashes to the Crashpad handler. On macOS, this is applicable to this process and all subsequent child processes. On other platforms, child processes must also register by using SetHandlerIPCPipe(). For more information on configuring the crashpad handler, see crashpad_handler.
If you also want Crashpad to upload crashes to Sentry, additionally configure the Crashpad database for automatic uploads:
// #include "client/crash_report_database.h"
base::FilePath database("path/to/crashpad/db");
std::unique_ptr<CrashReportDatabase> db =
crashpad::CrashReportDatabase::Initialize(database);
if (db != nullptr && db->GetSettings() != nullptr) {
db->GetSettings()->SetUploadsEnabled(true);
}
By default, the crashpad handler will limit uploads to one per hour. To disable this limitation, pass the --no-rate-limit argument to the handler:
arguments.push_back("--no-rate-limit");
Our documentation is open source and available on GitHub. Your contributions are welcome, whether fixing a typo (drat!) or suggesting an update ("yeah, this would be better").
