Nguyễn Thái Ngọc Duy	65f099b398	switch: no worktree status unless real branch switch happens When we switch from one branch to another, it makes sense to show a summary of local changes since there could be conflicts, or some files left modified.... When switch is used solely for creating a new branch (and "switch" to the same commit) or detaching, we don't really need to show anything. "git checkout" does it anyway for historical reasons. But we can start with a clean slate with switch and don't have to. This essentially reverts `fa655d8411` (checkout: optimize "git checkout -b <new_branch>" - 2018-08-16) and make it default for switch, but also for -B and --detach. Users of big repos are encouraged to move to switch. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	6 years ago
Jonathan Tan	2f215ff10b	cache-tree: skip some blob checks in partial clone In a partial clone, whenever a sparse checkout occurs, the existence of all blobs in the index is verified, whether they are included or excluded by the .git/info/sparse-checkout specification. This significantly degrades performance because a lazy fetch occurs whenever the existence of a missing blob is checked. This is because cache_tree_update() checks the existence of all objects in the index, whether or not CE_SKIP_WORKTREE is set on them. Teach cache_tree_update() to skip checking CE_SKIP_WORKTREE objects when the repository is a partial clone. This improves performance for sparse checkout and also other operations that use cache_tree_update(). Instead of completely removing the check, an argument could be made that the check should instead be replaced by a check that the blob is promised, but for performance reasons, I decided not to do this. If the user needs to verify the repository, it can be done using fsck (which will notify if a tree points to a missing and non-promised blob, whether the blob is included or excluded by the sparse-checkout specification).

Ben Peart	fa655d8411	checkout: optimize "git checkout -b <new_branch>" Skip merging the commit, updating the index and working directory if and only if we are creating a new branch via "git checkout -b <new_branch>." Any other checkout options will still go through the former code path. If sparse_checkout is on, require the user to manually opt in to this optimzed behavior by setting the config setting checkout.optimizeNewBranch to true as we will no longer update the skip-worktree bit in the index, nor add/remove files in the working directory to reflect the current sparse checkout settings. For comparison, running "git checkout -b <new_branch>" on a large repo takes: 14.6 seconds - without this patch 0.3 seconds - with this patch Signed-off-by: Ben Peart <Ben.Peart@microsoft.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>	7 years ago
David Turner	7d782416cb	unpack-trees: don't update files with CE_WT_REMOVE set Don't update files in the worktree from cache entries which are flagged with CE_WT_REMOVE. When a user does a sparse checkout, git removes files that are marked with CE_WT_REMOVE (because they are out-of-scope for the sparse checkout). If those files are also marked CE_UPDATE (for instance, because they differ in the branch that is being checked out and the outgoing branch), git would previously recreate them. This patch prevents them from being recreated. These erroneously-created files would also interfere with merges, causing pre-merge revisions of out-of-scope files to appear in the worktree. apply_sparse_checkout() is the function where all "action" manipulation (add, delete, update files..) for sparse checkout occurs; it should not ask to delete and update both at the same time.
