From 63d428e656edcd670fa87e74136726096ff3de6f Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 8 Feb 2017 15:53:19 -0500 Subject: receive-pack: avoid duplicates between our refs and alternates We de-duplicate ".have" refs among themselves, but never check if they are duplicates of our local refs. It's not unreasonable that they would be if we are a "--shared" or "--reference" clone of a similar repository; we'd have all the same tags. We can handle this by inserting our local refs into the oidset, but obviously not suppressing duplicates (since the refnames are important). Note that this also switches the order in which we advertise refs, processing ours first and then any alternates. The order shouldn't matter (and arguably showing our refs first makes more sense).
