* Teach @{upstream} syntax to strbuf_branchanme()Junio C Hamano2010-01-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This teaches @{upstream} syntax to interpret_branch_name(), instead of dwim_ref() machinery. There are places in git UI that behaves differently when you give a local branch name and when you give an extended SHA-1 expression that evaluates to the commit object name at the tip of the branch. The intent is that the special syntax such as @{-1} can stand in as if the user spelled the name of the branch in such places. The name of the branch "frotz" to switch to ("git checkout frotz"), and the name of the branch "nitfol" to fork a new branch "frotz" from ("git checkout -b frotz nitfol"), are examples of such places. These places take only the name of the branch (e.g. "frotz"), and they are supposed to act differently to an equivalent refname (e.g. "refs/heads/frotz"), so hooking the @{upstream} and @{-N} syntax to dwim_ref() is insufficient when we want to deal with cases a local branch is forked from another local branch and use "forked@{upstream}" to name the forkee branch. The "upstream" syntax "forked@{u}" is to specify the ref that "forked" is configured to merge with, and most often the forkee is a remote tracking branch, not a local branch. We cannot simply return a local branch name, but that does not necessarily mean we have to returns the full refname (e.g. refs/remotes/origin/frotz, when returning origin/frotz is enough). This update calls shorten_unambiguous_ref() to do so. Signed-off-by: Junio C Hamano <gitster@pobox.com>
* t1506: more test for @{upstream} syntaxJunio C Hamano2010-01-20
| | | | | | | | This adds a few more tests that exercises @{upstream} syntax by commands that operate differently when they are given branch name as opposed to a refname (i.e. where "master" and "refs/heads/master" makes a difference). Signed-off-by: Junio C Hamano <gitster@pobox.com>
* Introduce <branch>@{upstream} notationJohannes Schindelin2010-01-12
| | | | | | | | | | | | | | | | | | | A new notation '<branch>@{upstream}' refers to the branch <branch> is set to build on top of. Missing <branch> (i.e. '@{upstream}') defaults to the current branch. This allows you to run, for example, for l in list of local branches do git log --oneline --left-right $l...$l@{upstream} done to inspect each of the local branches you are interested in for the divergence from its upstream.

* | git-svn: detect cherry-picks correctly.Sam Vilain2009-12-21
| | | | | | | | | | | | | | | | | | | | | | | | The old function was incorrect; in some instances it marks a cherry picked range as a merged branch (because of an incorrect assumption that 'rev-list COMMIT --not RANGE' would work). This is replaced with a function which should detect them correctly, memoized to limit the expense of dealing with branches with many cherry picks to one 'merge-base' call per merge, per branch which used cherry picking.

| | | | | | | | | | | | | | | | | | | | | | | | If a command is run with an absolute path as a pathspec inside a bare repository, e.g. "rev-list HEAD -- /home", the code tried to run strlen() on NULL, which is the result of get_git_work_tree(), and segfaulted. It should just fail instead. Currently the function returns NULL even inside .git/ in a repository with a work tree, but that is a separate issue. Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * ignore unknown color configurationJeff King2009-12-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parsing the config file, if there is a value that is syntactically correct but unused, we generally ignore it. This lets non-core porcelains store arbitrary information in the config file, and it means that configuration files can be shared between new and old versions of git (the old versions might simply ignore certain configuration). The one exception to this is color configuration; if we encounter a color.{diff,branch,status}.$slot variable, we die if it is not one of the recognized slots (presumably as a safety valve for user misconfiguration). This behavior has existed since 801235c (diff --color: use $GIT_DIR/config, 2006-06-24), but hasn't yet caused a problem. No porcelain has wanted to store extra colors, and we once a color area (like color.diff) has been introduced, we've never changed the set of color slots. However, that changed recently with the addition of color.diff.func. Now a user with color.diff.func in their config can no longer freely switch between v1.6.6 and older versions; the old versions will complain about the existence of the variable. This patch loosens the check to match the rest of git-config; unknown color slots are simply ignored. This doesn't fix this particular problem, as the older version (without this patch) is the problem, but it at least prevents it from happening again in the future.

The approach it took was to factor out the "deleted" line from the patch header into its own hunk, the same way we do for mode changes. However, unlike mode changes, we only showed the special "delete this file" hunk if there were no other hunks. Otherwise, the user would annoyingly be presented with _two_ hunks: one for deleting the file and one for deleting the content. This meant that in the non-empty case, we forgot about the deleted line entirely, and we submitted a bogus patch to git-apply (with "/dev/null" as the destination file, but not marked as a deletion). Instead, this patch combines the file deletion hunk and the content deletion hunk (if there is one) into a single deletion hunk which is either staged or not.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing code checked to make sure we were not in a bare repository when doing a hard reset. However, we should take this one step further, and make sure we are in a worktree. Otherwise, we can end up munging files inside of '.git'. Furthermore, we should do the same check for --merge resets, which have the same properties. Actually, a merge reset of HEAD^ would already complain, since further down in the code we want a worktree. However, it is nicer to check up-front; then we are sure we cover all cases ("git reset --merge" would run, even though it wasn't doing anything) and we can give a more specific message. Add tests to t7103 to cover these cases and some missing ones. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>

However, there is an additional condition that must hold for valid subtree entries: They must be _tree_ objects (duh). This patch adds an appropriate test for this condition, thereby fixing the crash that occured when passing a non-tree object to the tree-walk API.

This is inconvenient when we just want to borrow the commit log message or when our change to the code is so significant that we should take over the authorship (with the blame for bugs we introduce, of course). The new --reset-author option is meant to solve this need by regenerating the timestamp and setting the committer as the new author.

Introduce a separate color and paint the hunk comment part, i.e. the name of the function, in a separate color "diff.func" (defaults to plain). Whitespace between hunk header and hunk comment is printed in plain color. Signed-off-by: Bert Wesarg <bert.wesarg@googlemail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

Stop the wastefulness. Signed-off-by: Junio C Hamano <gitster@pobox.com>
