Hmmm, I see that you changed the signature of update_refs() to take an
array of pointers. My suggestion was unclear, but I didn't mean that
the function signature had to be changed. Rather, I meant that *within*
the function, you could have created an array of pointers to the
structures in the input array and thereafter accessed it via the pointers:
int update_refs(const char *action, const struct ref_update *updates_orig,
int n, enum action_on_err onerr)
{
[...]
struct ref_update **updates;
[...]
updates = xcalloc(n, sizeof(*updates));
for (i = 0; i < n; i++)
updates[i] = &updates_orig[i];
[...]
}
However, your approach is also fine. It will typically involve more
malloc()s but smaller memcpy()s (i.e., via ALLOC_GROW()) at the caller,
and since usually the number of ref_updates being done at one time will
be limited anyway, I don't see a reason to prefer one version over the
other.
Thanks for making the change.
Michael
