From cc1b8d8bc6e453b96798574d67ce9590eb3e82e1 Mon Sep 17 00:00:00 2001 From: Jeff King Date: Wed, 17 Feb 2010 20:16:20 -0500 Subject: [PATCH] docs: don't talk about $GIT_DIR/refs/ everywhere It is misleading to say that we pull refs from $GIT_DIR/refs/*, because we may also consult the packed refs mechanism. These days we tend to treat the "refs hierarchy" as more of an abstract namespace that happens to be represented as $GIT_DIR/refs. At best, this is a minor inaccuracy, but at worst it can confuse users who then look in $GIT_DIR/refs and find that it is missing some of the refs they expected to see. This patch drops most uses of "$GIT_DIR/refs/*", changing them into just "refs/*", under the assumption that users can handle the concept of an abstract refs namespace. There are a few things to note: - most cases just dropped the $GIT_DIR/ portion. But for cases where that left _just_ the word "refs", I changed it to "refs/" to help indicate that it was a hierarchy. I didn't do the same for longer paths (e.g., "refs/heads" remained, instead of becoming "refs/heads/"). - in some cases, no change was made, as the text was explicitly about unpacked refs (e.g., the discussion in git-pack-refs). - In some cases it made sense instead to note the existence of packed refs (e.g., in check-ref-format and rev-parse).
