Rather than clutter the code with the same ereport over and over again (I
count 12 malloc's in guc.c alone), I'd like something like this:
void* malloc_or_fail(int elevel, size_t sz)
{ void* result; if(sz < 1) /* * Make sure we have something that can be passed to free() even *
whenthe size is zero. */ sz = 1;
result = malloc(sz); if(result == NULL) { ereport(elevel, (errcode(ERRCODE_OUT_OF_MEMORY),
errmsg("out of memory")));
/* Oops, ereport returned! Who called us with elevel < ERROR? */ exit(EXIT_FAILURE); } return result;
}
void* malloc_or_error(size_t sz)
{ return malloc_or_fail(ERROR, sz);
}
void* malloc_or_fatal(size_t sz)
{ return malloc_or_fail(FATAL, sz);
}
I search the code but the only thing I find that comes close is pq_malloc.
But that's a different thing altogether since it doesn't use ereport. I'm
sure I missed something somewhere but if not, perhaps the above functions
would make sense? If so, what's the best name for them and where should they
reside?
Kind regards,
