It does not resolve the problem. The interpreter internally
The Lua interpreter?
Yes.
must test result of EVERY function that may fail on memory allocations:
void * interpreter_function0() { p = interpreter_function1(); if (p == NULL) { some rollback operations return NULL; } }
Not sure to understand, but since memory allocation failure is signaled via an exception, the code flow is quite different.
From http://www.lua.org/source/5.1/ldo.c.html#luaD_rawrunprotected:
struct lua_longjmp lj; lj.status = 0; lj.previous = L->errorJmp; /* chain new error handler */ L->errorJmp = &lj;
LUAI_TRY(L, &lj, (*f)(L, ud); );
L->errorJmp = lj.previous; /* restore old error handler */ if (lj.status != 0) { ... if memory error, destroy the interpreter }
and: #define LUAI_TRY(L,c,a) if (setjmp((c)->b) == 0) { a }
I understand the exception mechanic, this way is easy to program - you do not need to worry about all these tests, but I'm not sure, that it is safe way.
Ah, ok. But do you have doubts only about handling memory allocation failures via exceptions, about exception handling in general or about exception handling as implemented in Lua?
