From dcb3450fd8785d76dd3d25aa49be66190aa5e7f3 Mon Sep 17 00:00:00 2001 From: Linus Torvalds Date: Wed, 3 May 2006 17:21:08 -0700 Subject: sha1_to_hex() usage cleanup Somebody on the #git channel complained that the sha1_to_hex() thing uses a static buffer which caused an error message to show the same hex output twice instead of showing two different ones. That's pretty easily rectified by making it uses a simple LRU of a few buffers, which also allows some other users (that were aware of the buffer re-use) to be written in a more straightforward manner.
