From fa7b3c2f752a10a5dca9989d4a1c4b93ffa7f943 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 12 Nov 2008 11:52:35 -0800 Subject: checkout: Fix "initial checkout" detection Earlier commit 5521883 (checkout: do not lose staged removal, 2008-09-07) tightened the rule to prevent switching branches from losing local changes, so that staged removal of paths can be protected, while attempting to keep a loophole to still allow a special case of switching out of an un-checked-out state. However, the loophole was made a bit too tight, and did not allow switching from one branch (in an un-checked-out state) to check out another branch. The change to builtin-checkout.c in this commit loosens it to allow this, by not insisting the original commit and the new commit to be the same. It also introduces a new function, is_index_unborn (and an associated macro, is_cache_unborn), to check if the repository is truly in an un-checked-out state more reliably, by making sure that $GIT_INDEX_FILE did not exist when populating the in-core index structure. A few places the earlier commit 5521883 added the check for the initial checkout condition are updated to use this function.
