From 09f0abb0efde83cfc4b850ebdc41f6ed3b61a123 Mon Sep 17 00:00:00 2001 From: Nikolai Merinov Date: Fri, 19 Oct 2018 15:07:05 +0500 Subject: init: --dissociate option to copy objects borrowed with --reference "repo init --reference" has two purposes: to decrease bandwidth used at clone time, and to decrease disk usage afterward, by using the reference repositories as an alternate store of objects even after the clone. The downside is that it makes the borrowing repositories dependent on the reference repositories, so it is easy to end up with missing objects by mistake after a cleanup operation like "git gc". To prevent that, v2.3.0-rc0~30^2 (clone: --dissociate option to mark that reference is only temporary, 2014-10-14), "git clone" gained a --dissociate option that makes --reference reuse objects from the reference repository at clone time but copy them over instead of using the reference as an alternate. This is more straightforward to use than plain --reference, at the cost of higher disk usage. Introduce a --dissociate to "repo init" that brings the same benefits to repo. The option is simply passed on to "git clone".
