Backtrace modifications

This repository contains modifications provided by Backtrace I/O.

Windows file attachment support

Provided by Ihor Dutchak.

There also exists a Backtrace-specific function:

bool StartHandlerForBacktrace(const base::FilePath& handler,
                              const base::FilePath& database,
                              const base::FilePath& metrics_dir,
                              const std::string& url,
                              const std::map<std::string, std::string>& annotations,
                              const std::vector<std::string>& arguments,
                              const std::map<std::string, std::string>& fileAttachments,
                              bool restartable,
                              bool asynchronous_start);

It's very similar to StartHandler, with the exception of the fileAttachments parameter, which is a map of upload file names to local file paths.

For example, the following code will upload the log file from the specified path as 2018-02-30.log:

std::map<std::string, std::string> files = {
    { "2018-02-30.log", "C:/my_app/2018-02-30.log" }
};

rc = client.StartHandlerForBacktrace(handler,
    db,
    db,
    url,
    annotations,
    arguments,
    files,
    true,
    true);

If one does not want to use a Backtrace-specific function, the same result of uploading a file attachment to Backtrace I/O can be achieved by adding elements to the arguments vector in the following format:

--attachment=attachment_$ATTACHMENT_NAME=$ATTACHMENT_FILE_PATH

For the above example of 2018-02-30.log, the code would look as follows:

arguments.push_back(
    "--attachment=attachment_2018-02-30.log=C:/my_app/2018-02-30.log"
);

Send reports using EXCEPTION_POINTERS in Windows

A new function has been added to CrashpadClient, useful, example, when dealing with vectored exceptions. Additionally, it does not require that the process must end (the exception may be handled).

static void DumpWithoutCrashWithException(EXCEPTION_POINTERS* pointer);
