From 617480d75bdca266d4549e4047452c633ddb7a52 Mon Sep 17 00:00:00 2001 From: Han-Wen Nienhuys Date: Wed, 19 May 2021 15:31:28 +0000 Subject: refs: make explicit that ref_iterator_peel returns boolean Use -1 as error return value throughout. This removes spurious differences in the GIT_TRACE_REFS output, depending on the ref storage backend active. Before, the cached ref_iterator (but only that iterator!) would return peel_object() output directly. No callers relied on the peel_status values beyond success/failure. All calls to these functions go through peel_iterated_oid(), which returns peel_object() as a fallback, but also squashing the error values. The iteration interface already passes REF_ISSYMREF and REF_ISBROKEN through the flags argument, so the additional error values in enum peel_status provide no value. The ref iteration interface provides a separate peel() function because certain formats (eg. packed-refs and reftable) can store the peeled object next to the tag SHA1. Passing the peeled SHA1 as an optional argument to each_ref_fn maps more naturally to the implementation of ref databases. Changing the code in this way is left for a future refactoring.
