It clones 3 MB instead of 28 MB, which is useful if you don't expect to need history but would still like to submit patches or even directly git push if you have commit access. It's a fairly large difference. It saves bandwidth and decreases the time it takes in order to start working rather than staring at a blinking cursor waiting to complete. It's also able to dynamically grow by using `git fetch --unshallow` to retrieve the rest of the history, so there are no actual downsides to using it when you don't need it. But never mind --depth=1, the original post also pointed out that modern revisions of the git-over-http protocol support status messages such as: remote: Enumerating objects: 110424, done. remote: Counting objects: 100% (110424/110424), done. remote: Compressing objects: 100% (28074/28074), done. remote: Total 110424 (delta 88325), reused 102158 (delta 81649) Receiving objects: 100% (110424/110424), 27.51 MiB | 4.49 MiB/s, done. Resolving deltas: 100% (88325/88325), done. It is also faster even without the depth setting (or rather, old-style git-over-http is just really slow): $ time git clone git://git.busybox.net/busybox/ # no TLS validation [...] real 0m15.574s user 0m10.526s sys 0m0.606s $ time git clone https://git.busybox.net/busybox/ # with TLS validation [...] real 2m12.699s user 0m17.903s sys 0m4.561s There are many good reasons to use modern versions of the wire transport protocol instead of old versions, I'm actually extremely bewildered that this is such a controversial topic. It really should not be controversial. It's a very simple, pure-benefit request that simply depends on whether the person in charge of the server infrastructure has a bit of time to switch it on and considers such to be a useful way to spend that time. -- Eli Schwartz Arch Linux Bug Wrangler and Trusted User
