From af008558cc2e16c96ddafc6c7a9453ea3d18957b Mon Sep 17 00:00:00 2001 From: Jonathan Tan Date: Wed, 6 Jun 2018 13:47:08 -0700 Subject: [PATCH] fetch-pack: clear marks before re-marking If tag following is required when using a transport that does not support tag following, fetch_pack() will be invoked twice in the same process, necessitating a clearing of the object flags used by fetch_pack() sometime during the second invocation. This is currently done in find_common(), which means that the invocation of mark_complete_and_common_ref() in do_fetch_pack() is useless. (This cannot be reproduced with Git alone, because all transports that come with Git support tag following.) Therefore, move this clearing from find_common() to its parent function do_fetch_pack(), right before it calls mark_complete_and_common_ref(). This has been occurring since the commit that introduced the clearing of marks, 420e9af498 ("Fix tag following", 2008-03-19). The corresponding code for protocol v2 in do_fetch_pack_v2() does not have this problem, as the clearing of flags is done before any marking (whether by rev_list_insert_ref_oid() or mark_complete_and_common_ref()).
