2015-02-18error: New convenience function error_report_err()Markus Armbruster
I've typed error_report("%s", error_get_pretty(ERR)) too many times already, and I've fixed too many instances of qerror_report_err(ERR) to error_report("%s", error_get_pretty(ERR)) as well. Capture the pattern in a convenience function. Since it's almost invariably followed by error_free(), stuff that into the convenience function as well. The next patch will put it to use.

2014-01-06error: Add error_abortPeter Crosthwaite
Add a special Error * that can be passed to error handling APIs to signal that any errors are fatal and should abort QEMU. There are two advantages to this: - allows for brevity when wishing to assert success of Error ** accepting APIs. No need for this pattern: Error * local_err = NULL; api_call(foo, bar, &local_err); assert_no_error(local_err); This also removes the need for _nofail variants of APIs with asserting call sites now reduced to 1LOC. - SIGABRT happens from within the offending API. When a fatal error occurs in an API call (when the caller is asserting sucess) failure often means the API itself is broken. With the abort happening in the API call now, the stack frames into the call are available at debug time. In the assert_no_error scheme the abort happens after the fact. The exact semantic is that when an error is raised, if the argument Error ** matches &error_abort, then the abort occurs immediately. The error messaged is reported. For error_propagate, if the destination error is &error_abort, then the abort happens at propagation time.
