|
* Augmenting errors at their creation site and their throw site.
|
|
*
|
|
* When errors are created, traceback data is added by built-in code
|
|
* and a user error handler (if defined) can process or replace the
|
|
* error. Similarly, when errors are thrown, a user error handler
|
|
* (if defined) can process or replace the error.
|
|
*
|
|
* Augmentation and other processing at error creation time is nice
|
|
* because an error is only created once, but it may be thrown and
|
|
* rethrown multiple times. User error handler registered for processing
|
|
* an error at its throw site must be careful to handle rethrowing in
|
|
* a useful manner.
|
|
*
|
|
* Error augmentation may throw an internal error (e.g. alloc error).
|
|
*
|
|
* Ecmascript allows throwing any values, so all values cannot be
|
|
* augmented. Currently, the built-in augmentation at error creation
|
|
* only augments error values which are Error instances (= have the
|
|
* built-in Error.prototype in their prototype chain) and are also
|
|
* extensible. User error handlers have no limitations in this respect.

/*
|
|
* Helper for calling a user error handler.
|
|
*
|
|
* 'thr' must be the currently active thread; the error handler is called
|
|
* in its context. The valstack of 'thr' must have the error value on
|
|
* top, and will be replaced by another error value based on the return
|
|
* value of the error handler.
|
|
*
|
|
* The helper calls duk_handle_call() recursively in protected mode.
|
|
* Before that call happens, no longjmps should happen; as a consequence,
|
|
* we must assume that the valstack contains enough temporary space for
|
|
* arguments and such.
|
|
*
|
|
* While the error handler runs, any errors thrown will not trigger a
|
|
* recursive error handler call (this is implemented using a heap level
|
|
* flag which will "follow" through any coroutines resumed inside the
|
|
* error handler). If the error handler is not callable or throws an
|
|
* error, the resulting error replaces the original error (for Duktape
|
|
* internal errors, duk_error_throw.c further substitutes this error with
|
|
* a DoubleError which is not ideal). This would be easy to change and
|
|
* even signal to the caller.
|
|
*
|
|
* The user error handler is stored in 'Duktape.errCreate' or
|
|
* 'Duktape.errThrow' depending on whether we're augmenting the error at
|
|
* creation or throw time. There are several alternatives to this approach,
|
|
* see doc/error-objects.rst for discussion.
|
|
*
|
|
* Note: since further longjmp()s may occur while calling the error handler
|
|
* (for many reasons, e.g. a labeled 'break' inside the handler), the
|
|
* caller can make no assumptions on the thr->heap->lj state after the
|
|
* call (this affects especially duk_error_throw.c). This is not an issue
|
|
* as long as the caller writes to the lj state only after the error handler
|
|
* finishes.
