* push: allow unqualified dest refspecs to DWIMJeff King2008-04-242-3/+69
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, a push like: git push remote src:dst would go through the following steps: 1. check for an unambiguous 'dst' on the remote; if it exists, then push to that ref 2. otherwise, check if 'dst' begins with 'refs/'; if it does, create a new ref 3. otherwise, complain because we don't know where in the refs hierarchy to put 'dst' However, in some cases, we can guess about the ref type of 'dst' based on the ref type of 'src'. Specifically, before complaining we now check: 2.5. if 'src' resolves to a ref starting with refs/heads or refs/tags, then prepend that to 'dst' So now this creates a new branch on the remote, whereas it previously failed with an error message: git push master:newbranch Note that, by design, we limit this DWIM behavior only to source refs which resolve exactly (including symrefs which resolve to existing refs). We still complain on a partial destination refspec if the source is a raw sha1, or a ref expression such as 'master~10'.

| * t5516: remove ambiguity test (1)Jeff King2008-04-231-13/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This test tried to push into a remote with ambiguous refs in remotes/$x/master and remotes/$y/master. However, the remote never actually tells us about the refs/remotes hierarchy, so we don't even see this ambiguity. The test happened to pass because we were simply looking for failure, and the test fails for another reason: the dst refspec does not exist and does not begin with refs/, making it invalid.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | When trying to import from svn using an author file, git-svn bails out if it encounters a blank author.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The documentation for git-imap-send suggests a tunnel setting such as Tunnel = "ssh -q user@server.com /usr/bin/imapd ./Maildir 2> /dev/null" which works wonderfully and doesn't require a username, password or port setting. However, git-imap-send currently requires that the imap.host variable be set in the config even when it was unused. This patch changes imap-send to only require that the imap.host setting is set if imap.tunnel is not set. Otherwise, server.host is set to "tunnel" for reporting purposes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally git-rebase was implemented in terms of "format-patch" piped to "am -3", to strike balance between speed (because it avoids a rather expensive read-tree/merge-recursive machinery most of the time) and flexibility (the magic "-3" allows it to fall back to 3-way merge as necessary). However, this combination has one flaw when dealing with a nonstandard commit log message format that has more than one lines in the first paragraph. This teaches "git am --rebasing" to take advantage of the fact that the mbox message "git rebase" prepares for it records the original commit object name, to get the log message from the original commit object instead.

* | | gitweb: Fix 'history' view for deleted files with historyJakub Narebski2008-04-182-3/+31

This commit fixes this bug. This bug occurs in the rare cases when "git log -- <path>" is empty and "git log --full-history -- <path>" is not, or to be more exact in the cases when full-history starts later than given branch. It can happen if you are using handcrafted gitwb URL, or if you follow generic 'history' link or bookmark for a file which got deleted. Gitweb tried to get file type ('tree', or 'blob', or even 'commit') from the commit we start searching from (where the file was not present), and not among found commits. This was the cause of "Use of uninitialized value" warnings. This commit also add tests for such situation to t9500 test. While we are it, return HTTP error if there is _no_ history; it means that file or directory was not found (for given branch). Also error out if type of item could not be found: it should not happen now, but better be sure. Signed-off-by: Jakub Narebski <jnareb@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

This could be especilally bad for "git bisect start" because as the file ".git/BISECT_NAMES" would not have been written, there would have been no attempt to clear the marked revisions on a "git bisect reset". That's because if there is no ".git/BISECT_NAMES" file, nothing is done to clean things up, as the bisect session is not supposed to have started. While at it, let's also create the ".git/BISECT_START" file, only after ".git/BISECT_NAMES" as been created.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To get the current HEAD when we start bisecting using for example "git bisect start", we first try "git symbolic-ref HEAD" to get a nice name, and if it fails, we fall back to "git rev-parse --verify HEAD". The problem is that when "git symbolic-ref HEAD" fails, it displays "fatal: ref HEAD not a symref", so it looks like "git bisect start" failed and does not accept detached HEAD, even if in fact it worked fine.

This makes it totally transparent to CVS users, but the instruction to set up CVS access for people with real shell access does not apply. Previous wording mentioning GIT_AUTHOR, GIT_COMMITTER variables was unclear that we really meant GIT_AUTHOR_(NAME|EMAIL), etc. Note that the .ssh/environment file is a good place to set these, and that the .bashrc is shell-specific.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This changes the search logic for describing a submodule from: - annotated tag - any tag - tag on a subsequent commit - commit id to - annotated tag - any tag - tag on a subsequent commit - local or remote branch - commit id The change is describing with respect to a branch before falling back to the commit id. By itself, git-submodule will maintain submodules as headless checkouts without ever making a local branch. In general, such heads can always be described relative to the remote branch regardless of existence of tags, and so provides a better fallback summary than just the commit id. This requires inserting an extra describe step as --contains is incompatible with --all, but the latter can be used with --always to fall back to a commit ID. Also, --contains implies --tags, so the latter is not needed. Signed-off-by: Mark Levedahl <mlevedahl@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
