Hi, note: this time, I haven't anything to show for in my repo; sorry.

My understanding of this point now: if we're fetching non-objects *(like packs, pack indices), we wouldn't display "Fetching X objects" at all, regardless of X. But if we're not fetching any non-objects and we're waiting for loose objects fetching to finish (ie. we're fetching 1 loose object or more), then we would display "Fetching X objects". >> The total number of objects (320) increases as we "walk" the commits; >> sometimes we need to fetch the "walked" objects, sometimes we don't >> (eg. in packs we've fetched already).

So my > suggestion doesn't quite work in that case. In addition to that, it isn't possible to calculate the number of pack indices to be fetched, because we're fetching them as we go along (see http.c::http_get_info_packs() in 'master'), so that's a potential problem. I wonder if you (or anyone reading this) has any suggestions on this? I still think we can use your idea of one-fetch-one-verify per pack, even though objects are fetched simultaneously. Here's what a "git clone http://repo"; would look like, after incorporating points from our discussion so far: Fetching info/refs: Z%, x MiB | y KiB/s, done Fetching objects/info/packs: Z%, x MiB | y KiB/s, done Fetching pack index (1 of 3): Z%, x MiB | y KiB/s, done Fetching pack index (2 of 3): Z%, x MiB | y KiB/s, done Fetching pack index (3 of 3): Z%, x MiB | y KiB/s, done Fetching pack (1 of 3): Z%, x MiB | y KiB/s, done Verifying pack (1 of 3): Z%, (X/Y), done Fetching pack (2 of 3): Z%, x MiB | y KiB/s, done Verifying pack (2 of 3): Z%, (X/Y), done Fetching pack (3 of 3): Z%, x MiB | y KiB/s, done Verifying pack (3 of 3): Z%, (X/Y), done Fetching 2 objects, done. Checking out files, done. (I made up the last line.) >> the linux-2.6 repo has only 1 pack (and no http-alternates), so this >> is weird. > > Maybe we are fetching from different places: Thanks. I realise the weird percentage values you saw were due to out-of-range numeric calculations, so actually, your point didn't count, but thanks anyway. -- Cheers, Ray Chuan -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
