* Merge branch 'fc/at-head'Junio C Hamano2013-09-207-7/+54
|\ | | | | | | | | | | | | | | | | Instead of typing four capital letters "HEAD", you can say "@" now, e.g. "git log @". * fc/at-head: Add new @ shortcut for HEAD sha1-name: pass len argument to interpret_branch_name()
| * Add new @ shortcut for HEADfc/at-headFelipe Contreras2013-09-125-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typing 'HEAD' is tedious, especially when we can use '@' instead. The reason for choosing '@' is that it follows naturally from the ref@op syntax (e.g. HEAD@{u}), except we have no ref, and no operation, and when we don't have those, it makes sens to assume 'HEAD'. So now we can use 'git show @~1', and all that goody goodness. Until now '@' was a valid name, but it conflicts with this idea, so let's make it invalid. Probably very few people, if any, used this name. Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
| * sha1-name: pass len argument to interpret_branch_name()Felipe Contreras2013-09-034-7/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | This is useful to make sure we don't step outside the boundaries of what we are interpreting at the moment. For example while interpreting foobar@{u}~1, the job of interpret_branch_name() ends right before ~1, but there's no way to figure that out inside the function, unless the len argument is passed. So let's do that. Signed-off-by: Felipe Contreras <felipe.contreras@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

|\ \ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "git check-ignore" follows the same rule as "git add" and "git status" in that the ignore/exclude mechanism does not take effect on paths that are already tracked. With "--no-index" option, it can be used to diagnose which paths that should have been ignored have been mistakenly added to the index. * dw/check-ignore-sans-index: check-ignore: Add option to ignore index contents
| * | check-ignore: Add option to ignore index contentsdw/check-ignore-sans-indexDave Williams2013-09-123-11/+74
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | check-ignore currently shows how .gitignore rules would treat untracked paths. Tracked paths do not generate useful output. This prevents debugging of why a path became tracked unexpectedly unless that path is first removed from the index with `git rm --cached <path>`. The option --no-index tells the command to bypass the check for the path being in the index and hence allows tracked paths to be checked too. Whilst this behaviour deviates from the characteristics of `git add` and `git status` its use case is unlikely to cause any user confusion. Test scripts are augmented to check this option against the standard ignores to ensure correct behaviour.

Many of them are not applicable when the commit has already been started, and should not be shown in COMMIT_EDITMSG. The most obvious are hints advising to run "git commit", "git rebase/am/cherry-pick --continue", which do not make sense when the command has already been run. Other messages become slightly inaccurate (e.g. hint to use "git add" to add untracked files), as the suggested commands are not immediately applicable during the editing of COMMIT_EDITMSG, but would be applicable if the commit is aborted. These messages are both potentially helpful and slightly misleading. This patch chose to remove them too, to avoid introducing too much complexity in the status code.

Add function 'update_refs' accepting an array of updates to perform. First sort the input array to order locks consistently everywhere and reject multiple updates to the same ref. Then acquire locks on all refs with verified old values. Then update or delete all refs accordingly. Fail if any one lock cannot be obtained or any one old value does not match. Though the refs themselves cannot be modified together in a single atomic transaction, this function does enable some useful semantics. For example, a caller may create a new branch starting from the head of another branch and rewind the original branch at the same time. This transfers ownership of commits between branches without risk of losing commits added to the original branch by a concurrent process, or risk of a concurrent process creating the new branch first.

However, if the matching refspec does not have refs/heads/<something> on the remote side, we end up rejecting the match, and failing the upstream configuration. It could be argued that when we set up an branch's upstream, we want that upstream to also be a proper branch in the remote repo. Although this is typically the common case, there are cases (as demonstrated by the previous patch in this series) where this requirement prevents a useful upstream relationship from being formed. Furthermore: - We have fundamentally no say in how the remote repo have organized its branches. The remote repo may put branches (or branch-like constructs that are insteresting for downstreams to track) outside refs/heads/*. - The user may intentionally want to track a non-branch from a remote repo, by using a branch and configured upstream in the local repo. Relaxing the checking to only require a matching remote/refspec allows the testcase introduced in the previous patch to succeed, and has no negative effect on the rest of the test suite. This patch fixes a behavior (arguably a regression) first introduced in 41c21f2 (branch.c: Validate tracking branches with refspecs instead of refs/remotes/*) on 2013-04-21 (released in >= v1.8.3.2).

We now use the configured remotes and their refspecs to determine whether a proposed tracking branch is in fact within the domain of a remote, and we then use that information to deduce the upstream configuration (branch.<name>.remote and branch.<name>.merge). However, with that change, we also check that - in addition to a matching refspec - the result of mapping the tracking branch through that refspec (i.e. the corresponding ref name in the remote repo) happens to start with "refs/heads/". In other words, we require that a tracking branch refers to a _branch_ in the remote repo. Now, consider that you are e.g. setting up an automated building/testing infrastructure for a group of similar "source" repositories. The build/test infrastructure consists of a central scheduler, and a number of build/test "slave" machines that perform the actual build/test work. The scheduler monitors the group of similar repos for changes (e.g. with a periodic "git fetch"), and triggers builds/tests to be run on one or more slaves. Graphically the changes flow between the repos like this: Source #1 -------v ----> Slave #1 / Source #2 -----> Scheduler -----> Slave #2 \ Source #3 -------^ ----> Slave #3 ... ... The scheduler maintains a single Git repo with each of the source repos set up as distinct remotes. The slaves also need access to all the changes from all of the source repos, so they pull from the scheduler repo, but using the following custom refspec: remote.origin.fetch = "+refs/remotes/*:refs/remotes/*" This makes all of the scheduler's remote-tracking branches automatically available as identical remote-tracking branches in each of the slaves. Now, consider what happens if a slave tries to create a local branch with one of the remote-tracking branches as upstream: git branch local_branch --track refs/remotes/source-1/some_branch Git now looks at the configured remotes (in this case there is only "origin", pointing to the scheduler's repo) and sees refs/remotes/source-1/some_branch matching origin's refspec. Mapping through that refspec we find that the corresponding remote ref name is "refs/remotes/source-1/some_branch". However, since this remote ref name does not start with "refs/heads/", we discard it as a suitable upstream, and the whole command fails. This patch adds a testcase demonstrating this failure by creating two source repos ("a" and "b") that are forwarded through a scheduler ("c") to a slave repo ("d"), that then tries create a local branch with an upstream. See the next patch in this series for the exciting conclusion to this story...

However, when doing "git fetch local" to ensure the existence of refs/remotes/local/master, we must not already have changed remote.local.fetch so as to cause refs/remotes/local/master not to be fetched. Therefore, set remote.local.fetch to refs/heads/*:refs/remotes/local/* BEFORE we fetch, and then reset it to refs/heads/s:refs/remotes/local/s AFTER we have fetched (but before we test --track).

This prefix comment has no real purpose when "git status" is ran from the command-line, and this may distract users from the real content. Disable this prefix comment by default, and make it re-activable for users needing backward compatibility with status.displayCommentPrefix. Obviously, "git commit" ignores status.displayCommentPrefix and keeps the comment unconditionnaly when writing to COMMIT_EDITMSG (but not when writing to stdout for an error message or with --dry-run).

We could avoid these magic numbers by using skip_prefix. But taking a step back, we can realize that using the "commit_type" global is not really buying us anything. It is not ever going to change from being "commit" without causing severe breakage to existing uses. And even if it did change for some crazy reason, we would want to evaluate its effects on the "rev^{}" syntax, anyway. Let's just switch these to using a custom string literal, as we do for "rev^{object}". The resulting code is more robust to changes in the type strings, and is more readable.

This is because the function stat_tracking_info() can not distinguish invalid tracking branch from other cases which it would not like to report, such as there is no upstream settings at all, or nothing is changed between one branch and its upstream. Junio suggested missing upstream should be reported [1] like: $ git branch -v -v master e67ac84 initial * topic 3fc0f2a [topicbase: gone] topic $ git status # On branch topic # Your branch is based on 'topicbase', but the upstream is gone. # (use "git branch --unset-upstream" to fixup) ... $ git status -b -s ## topic...topicbase [gone] ... In order to do like that, we need to distinguish these three cases (i.e. no tracking, with configured but no longer valid tracking, and with tracking) in function stat_tracking_info(). So the refactored function stat_tracking_info() has three return values: -1 (with "gone" base), 0 (no base), and 1 (with base). If the caller does not like to report tracking info when nothing changed between the branch and its upstream, simply checks if num_theirs and num_ours are both 0.
