Re: ltask - A multi tasking library for lua

[David Crayford <dcrayford@...>]

Looks like a nice library but I'll have to give it a miss because of the 
unchecked mallocs.

    struct queue *q = malloc(sizeof(*q));
    // malloc never failed
    assert(q);

In my experience malloc does fail and quite often when running on a 
system with constrained memory. I see a lot of code with unchecked 
mallocs on github
and I don't like it. If it's too much effort to check return values why 
not just wrapper malloc/calloc so OOM failures set a message and exit 
cleanly? Of course,
it's not just open source code that has this issue. I've raised many 
tickets for expensive enterprise software with the same problem.
