* Error handling macros, assertion macro, error codes.
|
||
|
|
*
|
||
|
|
* There are three types of 'errors':
|
||
|
|
*
|
||
|
|
* 1. Ordinary errors relative to a thread, cause a longjmp, catchable.
|
||
|
|
* 2. Fatal errors relative to a heap, cause fatal handler to be called.
|
||
|
|
* 3. Fatal errors without context, cause the default (not heap specific)
|
||
|
|
* fatal handler to be called.
|
||
|
|
*
|
||
|
|
* Fatal errors without context are used by debug code such as assertions.
|
||
|
|
* By providing a fatal error handler for a Duktape heap, user code can
|
||
|
|
* avoid fatal errors without context in non-debug builds.

* Normal error
|

|
|

|

|
|
* Normal error is thrown with a longjmp() through the current setjmp()
|
||
|
|
* catchpoint record in the duk_heap. The 'curr_thread' of the duk_heap
|
||
|
|
* identifies the throwing thread.
|
||
|
|
*
|
||
|
|
* Error formatting is usually unnecessary. The error macros provide a
|
||
|
|
* zero argument version (no formatting) and separate macros for small
|
||
|
|
* argument counts. Variadic macros are not used to avoid portability
|
||
|
|
* issues and avoid the need for stash-based workarounds when they're not
|
||
|
|
* available. Vararg calls are avoided for non-formatted error calls
|
||
|
|
* because vararg call sites are larger than normal, and there are a lot
|
||
|
|
* of call sites with no formatting.
|
||
|
|
*
|
||
|
|
* Note that special formatting provided by debug macros is NOT available.
|
||
|
|
*
|
||
|
|
* The _RAW variants allow the caller to specify file and line. This makes
|
||
|
|
* it easier to write checked calls which want to use the call site of the
|
||
|
|
* checked function, not the error macro call inside the checked function.
