2011-09-16branch --set-upstream: regression fixLibravatar Junio C Hamano1-1/+2
The "git branch" command, while not in listing mode, calls create_branch() even when the target branch already exists, and it does so even when it is not interested in updating the value of the branch (i.e. the name of the commit object that sits at the tip of the existing branch). This happens when the command is run with "--set-upstream" option. The earlier safety-measure to prevent "git branch -f $branch $commit" from updating the currently checked out branch did not take it into account, and we no longer can update the tracking information of the current branch. Minimally fix this regression by telling the validation code if it is called to really update the value of a potentially existing branch, or if the caller merely is interested in updating auxiliary aspects of a branch.

2011-08-22Prevent force-updating of the current branchLibravatar Conrad Irwin1-9/+3
"git branch -M <foo> <current-branch>" allows updating the current branch which HEAD points, without the necessary house-keeping that git reset normally does to make this operation sensible. It also leaves the reflog in a confusing state (you would be warned when trying to read it). "git checkout -B <current branch> <foo>" is also partly vulnerable to this bug; due to inconsistent pre-flight checks it would perform half of its task and then abort just before rewriting the branch. Again this manifested itself as the index file getting out-of-sync with HEAD. "git branch -f" already guarded against this problem, and aborts with a fatal error. Update "git branch -M", "git checkout -B" and "git branch -f" to share the same check before allowing a branch to be created. These prevent you from updating the current branch. We considered suggesting the use of "git reset" in the failure message but concluded that it was not possible to discern what the user was actually trying to do.

2011-08-11ls-files: fix pathspec display on errorLibravatar Clemens Buchacher1-3/+3
The following sequence of commands reveals an issue with error reporting of relative paths: $ mkdir sub $ cd sub $ git ls-files --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. $ git commit --error-unmatch ../bbbbb error: pathspec 'b' did not match any file(s) known to git. This bug is visible only if the normalized path (i.e., the relative path from the repository root) is longer than the prefix. Otherwise, the code skips over the normalized path and reads from an unused memory location which still contains a leftover of the original command line argument. So instead, use the existing facilities to deal with relative paths correctly. Also fix inconsistency between "checkout" and "commit", e.g. $ cd Documentation $ git checkout nosuch.txt error: pathspec 'Documentation/nosuch.txt' did not match... $ git commit nosuch.txt error: pathspec 'nosuch.txt' did not match... by propagating the prefix down the codepath that reports the error.

2011-06-05checkout -b <name>: correctly detect existing branchLibravatar Junio C Hamano1-1/+1
When create a new branch, we fed "refs/heads/<proposed name>" as a string to get_sha1() and expected it to fail when a branch already exists. The right way to check if a ref exists is to check with resolve_ref(). A naïve solution that might appear attractive but does not work is to forbid slashes in get_describe_name() but that will not work. A describe name is is in the form of "ANYTHING-g<short sha1>", and that ANYTHING part comes from a original tag name used in the repository the user ran the describe command. A sick user could have a confusing hierarchical tag whose name is "refs/heads/foobar" (stored as refs/tags/refs/heads/foobar") to generate a describe name "refs/heads/foobar-6-g02ac983", and we should be able to use that name to refer to the object whose name is 02ac983.

2011-05-24checkout: make advice when reattaching the HEAD less loudLibravatar Junio C Hamano1-6/+9
When switching away from a detached HEAD with "git checkout", we give a listing of the commits about to be lost, and then tell how to resurrect them since 8e2dc6a (commit: give final warning when reattaching HEAD to leave commits behind, 2011-02-18). This is a good safety measure for people who are not comfortable with the detached HEAD state, but the advice on how to keep the state you just left was given even to those who set advice.detachedHead to false. Keep the warning and informational commit listing, but honor the setting of advice.detachedHead to squelch the advice.

2011-03-20checkout: tweak detached-orphan warning formatLibravatar Jeff King1-1/+4
When orphaning a commit on a detached HEAD, the warning currently looks like: Warning: you are leaving 3 commits behind, not connected to any of your branches: - commit subject 1 - commit subject 2 - commit subject 3 If you want to keep them by creating a new branch, this may be a good time to do so with: git branch new_branch_name 933a615ab0bc566dcfd8c01ec8af159f770d3fe5 Instead of using the "-" list, let's provide a more traditional oneline format, with the abbreviated sha1 before each subject. Users are accustomed to seeing commits in this format, and having the sha1 of each commit can be useful if you want to cherry-pick instead of creating a new branch. The new format looks like: Warning: you are leaving 3 commits behind, not connected to any of your branches: 933a615 commit subject 1 824fcde commit subject 2 fa49b1a commit subject 3 Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2011-02-23commit: give final warning when reattaching HEAD to leave commits behindLibravatar Junio C Hamano1-6/+95
You can detach the HEAD at an arbitrary commit in order to browse the files in various points in the history or build older versions of the software, without recording any new commit, and come back to an existing branch. When used in this "sightseer" mode, detached HEAD is a perfectly safe mechanism. It also is a useful state to experiment with throw-away commits. When coming back to an existing branch with "git checkout master", however, the commits that were created on the detached HEAD will become unreachable from anywhere but the reflog of the HEAD. Check if the commit we are about to leave is connected to some ref, and give a final warning otherwise to remind the user for safety. Signed-off-by: Junio C Hamano <gitster@pobox.com>

Functions such as hashcmp that expect a binary SHA-1 value take parameters of type "unsigned char *" to avoid accepting a textual SHA-1 passed by mistake. Unfortunately, this means passing the string literal EMPTY_TREE_SHA1_BIN requires an ugly cast. Tweak the definition of EMPTY_TREE_SHA1_BIN to produce a value of more convenient type. In the future the definition might change to extern const unsigned char empty_tree_sha1_bin[20]; #define EMPTY_TREE_SHA1_BIN empty_tree_sha1_bin Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Take care of simple, exceptional cases before the meat of the "check out by branch name" code begins.

2011-01-11checkout: fix bug with ambiguous refsLibravatar Junio C Hamano1-10/+13
The usual dwim_ref lookup prefers tags to branches. Because checkout primarily works on branches, though, we switch that behavior to prefer branches. However, there was a bug in the implementation in which we used lookup_commit_reference (which used the regular lookup rules) to get the actual commit to checkout. Checking out an ambiguous ref therefore ended up putting us in an extremely broken state in which we wrote the branch ref into HEAD, but actually checked out the tree for the tag. This patch fixes the bug by always attempting to pull the commit to be checked out from the branch-ified version of the name we were given. Patch by Junio, tests and commit message from Jeff King.
