I was preparing the reroll and I saw that I had missed your mail.
I think that I haven't changed the behaviour, the original one is
written in callback form so it has to go through the array every time for each
new value.
When there are multiple entries for a service say,
http.receivepack = 1
http.receivepack = 0
the old code would have at overwritten the previous entry with the new value.
The new code just populates the whole array of `rpc_service` in one go, choosing
the last matching value for each entry. For reviewing purpose the original array is
this,
struct rpc_service {
const char *name;
const char *config_name;
signed enabled : 2;
};
static struct rpc_service rpc_service[] = {
{ "upload-pack", "uploadpack", 1 },
{ "receive-pack", "receivepack", -1 },
};
What do you think, am I interpreting it wrong? Thanks.
