2012-10-18branch: show targets of deleted symrefs, not sha1sLibravatar René Scharfe1-8/+11
git branch reports the abbreviated hash of the head commit of a deleted branch to make it easier for a user to undo the operation. For symref branches this doesn't help. Print the symref target instead for them. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-10-18branch: skip commit checks when deleting symref branchesLibravatar René Scharfe1-2/+8
Before a branch is deleted, we check that it points to a valid commit. With -d we also check that the commit is a merged; this check is not done with -D. The reason for that is that commits pointed to by branches should never go missing; if they do then something broke and it's better to stop instead of adding to the mess. And a non-merged commit may contain changes that are worth preserving, so we require the stronger option -D instead of -d to get rid of them. If a branch consists of a symref, these concerns don't apply. Deleting such a branch can't make a commit become unreferenced, so we don't need to check if it is merged, or even if it is actually a valid commit. Skip them in that case. This allows us to delete dangling symref branches. Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-10-18branch: delete symref branch, not its targetLibravatar René Scharfe1-1/+1

mistaken use This interface is error prone, and a better one (--set-upstream-to) exists. Add a message listing the alternatives and suggest how to fix a --set-upstream invocation in case the user only gives one argument which causes a local branch with the same name as a remote-tracking one to be created. The typical case is git branch --set-upstream origin/master when the user meant git branch --set-upstream master origin/master assuming that the current branch is master. Show a message telling the user how to undo their action and get what they wanted. For the command above, the message would be The --set-upstream flag is deprecated and will be removed.

2012-08-27branch -v: align even when branch names are in UTF-8Libravatar Nguyễn Thái Ngọc Duy1-13/+15
Branch names are usually in ASCII so they are not the problem. The problem most likely comes from "(no branch)" translation, which is in UTF-8 and makes display-width calculation just wrong. Clarify this by renaming the field "len" in struct ref_item to "width", as it stores the display-width and is used to compute the width of the screen needed to show the names of all the branches, and compute the display width using utf8_strwidth(), not byte-length with strlen(). Update document to mention the fact that we may want ref names in UTF-8. Encodings that produce invalid UTF-8 are safe as utf8_strwidth() falls back to strlen(). The ones that incidentally produce valid UTF-8 sequences will cause misalignment. Signed-off-by: Nguyễn Thái Ngọc Duy <pclouds@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2012-08-23branch: introduce --set-upstream-toLibravatar Carlos Martín Nieto1-2/+15
The existing --set-uptream option can cause confusion, as it uses the usual branch convention of assuming a starting point of HEAD if none is specified, causing git branch --set-upstream origin/master to create a new local branch 'origin/master' that tracks the current branch. As --set-upstream already exists, we can't simply change its behaviour. To work around this, introduce --set-upstream-to which accepts a compulsory argument indicating what the new upstream branch should be and one optinal argument indicating which branch to change, defaulting to HEAD. The new options allows us to type git branch --set-upstream-to origin/master to set the current branch's upstream to be origin's master.

2012-02-27branch: don't assume the merge filter ref existsLibravatar Carlos Martín Nieto1-0/+4
print_ref_list looks up the merge_filter_ref and assumes that a valid pointer is returned. When the object doesn't exist, it tries to dereference a NULL pointer. This can be the case when git branch --merged is given an argument that isn't a valid commit name. Check whether the lookup returns a NULL pointer and die with an error if it does.

2012-02-05branch --edit-description: protect against mistyped branch nameLibravatar Junio C Hamano1-0/+15
It is very easy to mistype the branch name when editing its description, e.g. $ git checkout -b my-topic master : work work work : now we are at a good point to switch working something else $ git checkout master : ah, let's write it down before we forget what we were doing $ git branch --edit-description my-tpoic The command does not notice that branch 'my-tpoic' does not exist. It is not lost (it becomes description of an unborn my-tpoic branch), but is not very useful. So detect such a case and error out to reduce the grief factor from this common mistake. This incidentally also errors out --edit-description when the HEAD points at an unborn branch (immediately after "init", or "checkout --orphan"), because at that point, you do not even have any commit that is part of your history and there is no point in describing how this particular branch is different from the branch it forked off of, which is the useful bit of information the branch description is designed to capture. We may want to special case the unborn case later, but that is outside the scope of this patch to prevent more common mistakes before 1.7.9 series gains too much widespread use.

2011-12-05Copy resolve_ref() return value for longer useLibravatar Nguyễn Thái Ngọc Duy1-1/+4
resolve_ref() may return a pointer to a static buffer. Callers that use this value longer than a couple of statements should copy the value to avoid some hidden resolve_ref() call that may change the static buffer's value. The bug found by Tony Wang <wwwjfy@gmail.com> in builtin/merge.c demonstrates this. The first call is in cmd_merge() branch = resolve_ref("HEAD", head_sha1, 0, &flag); Then deep in lookup_commit_or_die() a few lines after, resolve_ref() may be called again and destroy "branch". lookup_commit_or_die lookup_commit_reference lookup_commit_reference_gently parse_object lookup_replace_object do_lookup_replace_object prepare_replace_object for_each_replace_ref do_for_each_ref get_loose_refs get_ref_dir get_ref_dir resolve_ref All call sites are checked and made sure that xstrdup() is called if the value should be saved.

resolve_ref() may return a pointer to a static buffer, which is not safe for long-term use because if another resolve_ref() call happens, the buffer may be changed. Many call sites though do not care about this buffer. They simply check if the return value is NULL or not. Convert all these call sites to new wrappers to reduce resolve_ref() calls from 57 to 34.

2011-09-16branch --set-upstream: regression fixLibravatar Junio C Hamano1-1/+1
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.
