2007-11-29git checkout's reflog: even when detaching the HEAD, say from whereJohannes Schindelin
When checking out another ref, the reflogs already record from which branch you switched. Do that also when switching to a detached HEAD. While at it, record also when coming _from_ a detached HEAD.

2007-11-25git-checkout: describe detached head correctlyJunio C Hamano
When you have a file called HEAD in the work tree, the code to report where the HEAD is at when "git checkout $commit^0" is done triggered unnecessary ambiguity checking. Explicitly mark the command line with "--" and make it clear that we are talking about a revision. Signed-off-by: Junio C Hamano <gitster@pobox.com>

* maint: checkout: do not get confused with ambiguous tag/branch names
2007-06-08checkout: do not get confused with ambiguous tag/branch namesJunio C Hamano
Although it is not advisable, we have always allowed a branch and a tag to have the same basename (i.e. it is not illegal to have refs/heads/frotz and refs/tags/frotz at the same time). When talking about a specific commit, the interpretation of 'frotz' has always been "use tag and then check branch", although we warn when ambiguities exist. However "git checkout $name" is defined to (1) first see if it matches the branch name, and if so switch to that branch; (2) otherwise it is an instruction to detach HEAD to point at the commit named by $name. We did not follow this definition when $name appeared under both refs/heads/ and refs/tags/ -- we switched to the branch but read the tree from the tagged commit, which was utterly bogus.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have crept in to our source files over time.

2007-04-04checkout: allow detaching to HEAD even when switching to the tip of a branchJunio C Hamano
You cannot currently checkout the tip of an existing branch without moving to the branch. This allows you to detach your HEAD and place it at such a commit, with: $ git checkout master^0 Signed-off-by: Junio C Hamano <junkio@cox.net>
2007-03-23checkout: report where the new HEAD is upon detaching HEADJunio C Hamano

2007-03-16git-fetch, git-branch: Support local --track via a special remote '.'Paolo Bonzini
This patch adds support for a dummy remote '.' to avoid having to declare a fake remote like [remote "local"] url = . fetch = refs/heads/*:refs/heads/* Such a builtin remote simplifies the operation of "git-fetch", which will populate FETCH_HEAD but will not pretend that two repositories are in use, will not create a thin pack, and will not perform any useless remapping of names. The speed improvement is around 20%, and it should improve more if "git-fetch" is converted to a builtin. To this end, git-parse-remote is grown with a new kind of remote, 'builtin'. In git-fetch.sh, we treat the builtin remote specially in that it needs no pack/store operations. In fact, doing git-fetch on a builtin remote will simply populate FETCH_HEAD appropriately. The patch also improves of the --track/--no-track support, extending it so that branch.<name>.remote items referring '.' can be created. Finally, it fixes a typo in git-checkout.sh.

2007-03-11git-branch, git-checkout: autosetup for remote branch trackingPaolo Bonzini
In order to track and build on top of a branch 'topic' you track from your upstream repository, you often would end up doing this sequence: git checkout -b mytopic origin/topic git config --add branch.mytopic.remote origin git config --add branch.mytopic.merge refs/heads/topic This would first fork your own 'mytopic' branch from the 'topic' branch you track from the 'origin' repository; then it would set up two configuration variables so that 'git pull' without parameters does the right thing while you are on your own 'mytopic' branch. This commit adds a --track option to git-branch, so that "git branch --track mytopic origin/topic" performs the latter two actions when creating your 'mytopic' branch. If the configuration variable branch.autosetupmerge is set to true, you do not have to pass the --track option explicitly; further patches in this series allow setting the variable with a "git remote add" option. The configuration variable is off by default, and there is a --no-track option to countermand it even if the variable is set.

2007-02-04Let git-checkout always drop any detached headNicolas Pitre
We used to refuse leaving a detached HEAD when it wasn't matching an existing ref so not to lose any commit that might have been performed while not on any branch (unless -f was provided). But this protection was completely bogus since it was still possible to move to HEAD^ while still remaining detached but losing the last commit anyway if there was one. Now that we have a proper reflog for HEAD it is best to simply remove that bogus (and admitedly annoying) protection and simply display the last HEAD position instead. If one wants to recover a lost detached state then it can be retrieved from the HEAD reflog. Signed-off-by: Nicolas Pitre <nico@cam.org> Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-02-01detached HEAD -- finishing touchesJunio C Hamano
This updates "git-checkout" to report which branch you are switching to. Especially for people who do not use __git_ps1 from contrib/completion/git-completion.bash this would give a friendlier feedback of what is going on, and should make the reminder message much less scary. Here is a sample session (the prompt tells which branch I am on). * I have some local modification and realize that the change deserves to be on its own new topic branch. [git.git (master)]$ git diff --stat git-checkout.sh | 10 ++++++++-- 1 files changed, 8 insertions(+), 2 deletions(-) * So I switch to a new branch. I get a listing of local modifications and assuring "Switched to a new branch" message. [git.git (master)]$ git checkout -b jc/checkout M git-checkout.sh Switched to a new branch "jc/checkout" * If I switch back to "master", I get essentially the same. [git.git (jc/checkout)]$ git checkout master M git-checkout.sh Switched to branch "master" * Detaching head would say which commit I am at and reminds me that I am not on any branch (not that I would detach my HEAD while keeping precious local changes around in any real-world workflow -- this is just a sample session). [git.git (master)]$ git checkout master^ M git-checkout.sh Note: you are not on any branch and are at commit "master^" If you want to create a new branch from this checkout, you may do so (now or later) by using -b with the checkout command again. Example: git checkout -b <new_branch_name> * Coming back to an attached state can lose the detached HEAD, so I get warned and stopped. [git.git]$ git checkout master You are not on any branch and switching to branch 'master' may lose your changes. At this point, you can do one of two things: (1) Decide it is Ok and say 'git checkout -f master'; (2) Start a new branch from the current commit, by saying 'git checkout -b <branch-name>'. Leaving your HEAD detached; not switching to branch 'master'. * Moving around while my HEAD is detached is Ok. I still get the list of local modifications. [git.git]$ git checkout master^0 M git-checkout.sh * The previous step that switched to the tip commit is an obscure but useful trick. My HEAD is still detached but now it is pointed at by an existing ref, so I can come back safely. [git.git]$ git checkout master M git-checkout.sh Switched to branch "master" * And we are back on the "master" branch. [git.git (master)]$ exit Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-01-24git-checkout -m: fix merge caseJunio C Hamano
Commit c1a4278e switched the "merging checkout" implementation from 3-way read-tree to merge-recursive, but forgot that merge-recursive will signal an unmerged state with its own exit status code. This prevented the clean-up phase (paths cleanly merged should not be updated in the index) from running. Signed-off-by: Junio C Hamano <junkio@cox.net>

2007-01-10Disallow working directory commands in a bare repository.Shawn O. Pearce
If the user tries to run a porcelainish command which requires a working directory in a bare repository they may get unexpected results which are difficult to predict and may differ from command to command. Instead we should detect that the current repository is a bare repository and refuse to run the command there, as there is no working directory associated with it.

2007-01-10git-checkout: handle local changes sanely when detaching HEADJunio C Hamano
When switching branches, we usually first try read-tree to make sure that we do not lose the local changes and then updated the HEAD using update-ref.

2007-01-10git-checkout: safety check for detached HEAD checks existing refsJunio C Hamano
Checking for reachability from refs does not help much if the state we are currently on is somewhere in the middle. We will lose where we were.

2007-01-08Detached HEAD (experimental)Junio C Hamano
This allows "git checkout v1.4.3" to dissociate the HEAD of repository from any branch. After this point, "git branch" starts reporting that you are not on any branch. You can go back to an existing branch by saying "git checkout master", for example. This is still experimental. While I think it makes sense to allow commits on top of detached HEAD, it is rather dangerous unless you are careful in the current form. Next "git checkout master" will obviously lose what you have done, so we might want to require "git checkout -f" out of a detached HEAD if we find that the HEAD commit is not an ancestor of any other branches. There is no such safety valve implemented right now. On the other hand, the reason the user did not start the ad-hoc work on a new branch with "git checkout -b" was probably because the work was of a throw-away nature, so the convenience of not having that safety valve might be even better. The user, after accumulating some commits on top of a detached HEAD, can always create a new branch with "git checkout -b" not to lose useful work done while the HEAD was detached. We'll see.

2006-09-27Allow git-checkout when on a non-existant branch.Shawn Pearce
I've seen some users get into situtations where their HEAD symbolic-ref is pointing at a non-existant ref. (Sometimes this happens during clone when the remote repository lacks a 'master' branch.) If this happens the user is unable to use git-checkout to switch branches as there is no prior commit to merge from. So instead of giving the user low-level errors about how HEAD can't be resolved and how not a single revision was given change the type of checkout to be a force and go through with the user's request anyway.
