Created attachment 11920 [details] Output of "GIT_CURL_VERBOSE=1 GIT_TRACE=true git clone --verbose --depth 1 https://gerrit.wikimedia.org/r/p/mediawiki/core.git" When RobLa runs a shallow git-clone of core over HTTPS, the object count is 3,456. When I run it, it's 46,297.

(Please review the output before attaching it -- I'm not sure, but it's possible that it would contain your credentials, if you have any configured in git or .netrc.)
Is it possible that you have the equivalent of --no-single-branch in your configuration ? «When creating a shallow clone with the --depth option, this [--single-branch] is the default, unless --no-single-branch is given to fetch the histories near the tips of all branches.» Or it may be a git bug fixed in 1.7.10 PS: I get 2791 objects.

To make it even funnier, git 1.8.2 will contain more shallow fixes: commit 2532d891a4aab003a5ce19f04509fd8549754485 Merge: 9a6c84e cfb70e1 Author: Junio C Hamano <gitster@pobox.com> Date: Fri Feb 1 12:39:24 2013 -0800 Merge branch 'nd/fetch-depth-is-broken' "git fetch --depth" was broken in at least three ways. The resulting history was deeper than specified by one commit, it was unclear how to wipe the shallowness of the repository with the command, and documentation was misleading. * nd/fetch-depth-is-broken: fetch: elaborate --depth action upload-pack: fix off-by-one depth calculation in shallow clone fetch: add --unshallow for turning shallow repo into complete one
--single-branch was added in v1.7.10, which explains the difference of 46297 vs 3456. It seems still worth upgrading to v1.7.11.2, though: commit 4ac01b0cbc27b314333362e77323850e78a7448c Merge: c8382c1 0ec4b16 Author: Junio C Hamano <gitster@pobox.com> Date: Wed Jul 11 12:48:29 2012 -0700 Merge branch 'nd/clone-single-fix' into maint "git clone --single-branch" to clone a single branch did not limit the cloning to the specified branch. * nd/clone-single-fix: clone: fix ref selection in --single-branch --branch=xxx

The following workaround works for 1.7.9.5 and earlier: vagrant@precise32:~$ mkdir core ; cd core vagrant@precise32:~/core$ git init Initialized empty Git repository in /home/vagrant/core/.git/ vagrant@precise32:~/core$ time git fetch --depth=1 https://gerrit.wikimedia.org/r/p/mediawiki/core.git master:refs/remotes/origin/master remote: Counting objects: 2796, done remote: Finding sources: 100% (2796/2796) remote: Getting sizes: 100% (2666/2666) remote: Compressing objects: 67% (1806/2661) remote: Total 2796 (delta 298), reused 990 (delta 128) Receiving objects: 100% (2796/2796), 17.76 MiB | 373 KiB/s, done.
