packfile: remove GIT_DEBUG_LOOKUP log statements

jonathantanmy · gitster · commit 4669e7d68ec8 · 2018-02-15T13:08:53.000-08:00
In commit 628522e ("sha1-lookup: more memory efficient search in sorted list of SHA-1", 2008-04-09), a different algorithm for searching a sorted list was introduced, together with a set of log statements guarded by GIT_DEBUG_LOOKUP that are invoked both when using that algorithm and when using the existing binary search. Those log statements was meant for experiments and debugging, but with the removal of the aforementioned different algorithm in commit f1068ef ("sha1_file: drop experimental GIT_USE_LOOKUP search", 2017-08-09), those log statements are probably no longer necessary. Remove those statements. Signed-off-by: Jonathan Tan <jonathantanmy@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
