2019-04-02switch: no worktree status unless real branch switch happensLibravatar Nguyễn Thái Ngọc Duy1-126/+8
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>
2019-04-02switch: implicit dwim, use --no-guess to disable itLibravatar Nguyễn Thái Ngọc Duy1-8/+8
This is already the default in git-checkout. The real change in here is just minor cleanup. The main excuse is to explain why dwim is kept default. Contrary to detach mode that is easy to get into and confusing to get back out. Automatically creating a tracking branch often does not kick in as often (you would need a branch of the same name on a remote). And since the branch creation is reported clearly, the user should be able to undo/delete it if it's unwanted.

2019-04-02switch: add short option for --detachLibravatar Nguyễn Thái Ngọc Duy1-1/+1
"git checkout" automatically detaches branches and --detach is not that useful (--no-detach is more likely). But for "switch", you may want to use it more often once you're used to detached HEAD. This of course adds -d to git-checkout but it does not harm (yet?) to do it. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-04-02switch: only allow explicit detached HEADLibravatar Nguyễn Thái Ngọc Duy1-0/+34
"git checkout <commit>" will checkout the commit in question and detach HEAD from the current branch. It is naturally a right thing to do once you get git references. But detached HEAD is a scary concept to new users because we show a lot of warnings and stuff, and it could be hard to get out of (until you know better). To keep switch a bit more friendly to new users, we only allow entering detached HEAD mode when --detach is given. "git switch" must take a branch (unless you create a new branch, then of course switch can take any commit-ish) Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-04-02switch: reject "do nothing" caseLibravatar Nguyễn Thái Ngọc Duy1-0/+9
"git checkout" can be executed without any arguments. What it does is not exactly great: it switches from HEAD to HEAD and shows worktree modification as a side effect. Make switch reject this case. Just use "git status" if you want that side effect. For switch, you have to either - really switch a branch - (explicitly) detach from the current branch - create a new branch Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2019-04-02switch: stop accepting pathspecLibravatar Nguyễn Thái Ngọc Duy1-5/+15

2019-04-02switch: add --discard-changesLibravatar Nguyễn Thái Ngọc Duy1-2/+10
--discard-changes is a better name than --force for this option since it's what really happens. --force is turned to an alias for --discard-changes. But it's meant to be an alias for potentially more force options in the future. Side note. It's not obvious from the patch but --discard-changes also affects submodules if --recurse-submodules is used.

2019-04-02checkout: split part of it to new command 'switch'Libravatar Nguyễn Thái Ngọc Duy1-12/+48
"git checkout" doing too many things is a source of confusion for many users (and it even bites old timers sometimes). To remedy that, the command will be split into two new ones: switch and restore. The good old "git checkout" command is still here and will be until all (or most of users) are sick of it. See the new man page for the final design of switch. The actual implementation though is still pretty much the same as "git checkout" and not completely aligned with the man page. Following patches will adjust their behavior to match the man page.

2019-04-02checkout: inform the user when removing branch stateLibravatar Nguyễn Thái Ngọc Duy1-1/+1
After a successful switch, if a merge, cherry-pick or revert is ongoing, it is canceled. This behavior has been with us from the very early beginning, soon after git-merge was created but never actually documented [1]. It may be a good idea to be transparent and tell the user if some operation is canceled. I consider this a better way of telling the user than just adding a sentence or two in git-checkout.txt, which will be mostly ignored anyway. PS. Originally I wanted to print more details like warning: cancelling an in-progress merge from <SHA-1> which may allow some level of undo if the user wants to. But that seems a lot more work. Perhaps it can be improved later if people still want that. [1] ... and I will try not to argue whether it is a sensible behavior.

Since 0f086e6dca (checkout: print something when checking out paths - 2018-11-13), this command reports how many paths have been updated from what source (either from a tree, or from the index). I forget that there's a third source: when -m is used, the merge conflict is re-created (granted, also from the index, but it's not a straight copy from the index). Count and report unmerged paths separately. There's a bit more update to avoid reporting: Recreated X merge conflicts Updated 0 paths from the index The second line is unnecessary. Though if there's no conflict recreation, we still report Updated 0 paths from the index to make it clear we're not really doing anything.

2019-02-04revert "checkout: introduce checkout.overlayMode config"Libravatar Thomas Gummerer1-7/+1
This reverts 1495ff7da5 ("checkout: introduce checkout.overlayMode config", 2019-01-08) and thus removes the checkout.overlayMode config option. The option was originally introduced to give users the option to make the new no-overlay behaviour the default. However users may be using 'git checkout' in scripts, even though it is porcelain. Users setting the option to false may actually end up accidentally breaking scripts. With the introduction of a new subcommand that will make the behaviour the default, the config option will not be needed anymore anyway. Revert the commit and remove the config option, so we don't risk breaking scripts.

2019-01-08checkout: introduce --{,no-}overlay optionLibravatar Thomas Gummerer1-8/+58
Currently 'git checkout' is defined as an overlay operation, which means that if in 'git checkout <tree-ish> -- [<pathspec>]' we have an entry in the index that matches <pathspec>, but that doesn't exist in <tree-ish>, that entry will not be removed from the index or the working tree. Introduce a new --{,no-}overlay option, which allows using 'git checkout' in non-overlay mode, thus removing files from the working tree if they do not exist in <tree-ish> but match <pathspec>. Note that 'git checkout -p <tree-ish> -- [<pathspec>]' already works this way, so no changes are needed for the patch mode. We disallow 'git checkout --overlay -p' to avoid confusing users who would expect to be able to force overlay mode in 'git checkout -p' this way. Untracked files are not affected by this change, so 'git checkout --no-overlay HEAD -- untracked' will not remove untracked from the working tree. This is so e.g. 'git checkout --no-overlay HEAD -- dir/' doesn't delete all untracked files in dir/, but rather just resets the state of files that are known to git.

2018-11-14checkout: print something when checking out pathsLibravatar Nguyễn Thái Ngọc Duy1-8/+31
One of the problems with "git checkout" is that it does so many different things and could confuse people specially when we fail to handle ambiguation correctly. One way to help with that is tell the user what sort of operation is actually carried out. When switching branches, we always print something unless --quiet, either - "HEAD is now at ..." - "Reset branch ..." - "Already on ..." - "Switched to and reset ..." - "Switched to a new branch ..." - "Switched to branch ..." Checking out paths however is silent. Print something so that if we got the user intention wrong, they won't waste too much time to find that out. For the remaining cases of checkout we now print either - "Checked out ... paths out of the index" - "Checked out ... paths out of <abbrev hash>" Since the purpose of printing this is to help disambiguate. Only do it when "--" is missing. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2018-11-14checkout: disambiguate dwim tracking branches and local filesLibravatar Nguyễn Thái Ngọc Duy1-5/+13
When checkout dwim is added in [1], it is restricted to only dwim when certain conditions are met and fall back to default checkout behavior otherwise. It turns out falling back could be confusing. One of the conditions to turn git checkout frotz to git checkout -b frotz origin/frotz is that frotz must not exist as a file. But when the user comes to expect "git checkout frotz" to create the branch "frotz" and there happens to be a file named "frotz", git's silently reverting "frotz" file content is not helping. This is reported in Git mailing list [2] and even used as an example of "Git is bad" elsewhere [3]. We normally try to do the right thing, but when there are multiple "right things" to do, it's best to leave it to the user to decide. Check this case, ask the user to to disambiguate: - "git checkout -- foo" will check out path "foo" - "git checkout foo --" will dwim and create branch "foo" [4] For users who do not want dwim, use --no-guess. It's useless in this particular case because "git checkout --no-guess foo --" will just fail. But it could be used by scripts.

2018-08-29convert "oidcmp() == 0" to oideq()Libravatar Jeff King1-1/+1
Using the more restrictive oideq() should, in the long run, give the compiler more opportunities to optimize these callsites. For now, this conversion should be a complete noop with respect to the generated code. The result is also perhaps a little more readable, as it avoids the "zero is equal" idiom. Since it's so prevalent in C, I think seasoned programmers tend not to even notice it anymore, but it can sometimes make for awkward double negations (e.g., we can drop a few !!oidcmp() instances here). This patch was generated almost entirely by the included coccinelle patch. This mechanical conversion should be completely safe, because we check explicitly for cases where oidcmp() is compared to 0, which is what oideq() is doing under the hood. Note that we don't have to catch "!oidcmp()" separately; coccinelle's standard isomorphisms make sure the two are treated equivalently. I say "almost" because I did hand-edit the coccinelle output to fix up a few style violations (it mostly keeps the original formatting, but sometimes unwraps long lines).

The more library-ish parts of the codebase learned to work on the in-core index-state instance that is passed in by their callers, instead of always working on the singleton "the_index" instance. * nd/no-the-index: (24 commits) blame.c: remove implicit dependency on the_index apply.c: remove implicit dependency on the_index apply.c: make init_apply_state() take a struct repository apply.c: pass struct apply_state to more functions resolve-undo.c: use the right index instead of the_index archive-*.c: use the right repository archive.c: avoid access to the_index grep: use the right index instead of the_index attr: remove index from git_attr_set_direction() entry.c: use the right index instead of the_index submodule.c: use the right index instead of the_index pathspec.c: use the right index instead of the_index unpack-trees: avoid the_index in verify_absent() unpack-trees: convert clear_ce_flags* to avoid the_index unpack-trees: don't shadow global var the_index unpack-trees: add a note about path invalidation unpack-trees: remove 'extern' on function declaration ls-files: correct index argument to get_convert_attr_ascii() preload-index.c: use the right index instead of the_index dir.c: remove an implicit dependency on the_index in pathspec code ...
2018-08-16checkout: optimize "git checkout -b <new_branch>"Libravatar Ben Peart1-4/+116
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>
