This example has --depth=10, and on the server side at GitHub I have seen similar numbers from clients, especially CI services. (I take special note of such cases because --shallow quite often causes performance problems on the server side, though generally --depth=10 is not any worse than --depth=1. The worst case is really "--no-single-branch --depth=1", which wants a ton of objects but has to throw away all of the on-disk deltas). > > We are not really testing "does not imply" here, but "passing > > --shallow-submodules works".

Re: [BUG REPORT] git 2.9.0 clone --recursive fails on cloning a submodule
The problem is with other tools that use git, like Swift Package Manager - https://swift.org/package-manager/. Versions of git before 2.9.0 have no option --no-shallow-submodules. So the tools that use git would have to check if the version of git is greater than or equal 2.9.0 to know to specify that option.

Direct fetching of that commit > failed. The problem seems to be the shallow clone. The super-project points to a commit in the submodule that is not near the tip of any branch, so shallow-cloning the submodule means we don't get that commit. Prior to d22eb04 (clone: add `--shallow-submodules` flag, 2016-04-25), submodules were _always_ cloned fully. The immediate workaround is to add "--no-shallow-submodules" to your clone invocation. Stefan, I think it might be worth revisiting the default set by d22eb04 to propagate shallowness from the super-project clone. In an ideal world, we would be asking each submodule for the actual commit we are interested in, and shallowness would not matter. But until uploadpack.allowReachableSHA1InWant works everywhere, I suspect this is going to be a problem. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
