I have been feeling that the current behaviour of "git reset" is not quite optimal, but so far could not express exactly what I felt was wrong with it. This patch clarifies it. There are at least two situations you may want to "reset" your working tree. 1. You made a mess in your working tree. You want to switch back to a known good state and start over. This mess may be a result of your own editing, a merge that had too many conflicting changes that you do not feel like to resolve by hand at this moment, or a botched application of a patch you received from somewhere. In this case, you would want to have "git reset HEAD" reset the index file to the tree read from the HEAD commit and the files in the working tree to match index (i.e. "git status" should say "Nothing to commit", without any "unrecorded changes"). The current behaviour leaves the files in the working tree intact, which requires you to run "git checkout -f". Also you need to remember "rm -f" any files that the botched patch may have left in the working tree if the purpose of this "reset" is to attempt to apply it again; most likely the patch would fail if such a file is left behind. 2. You have discovered that commits you made earlier need to be reorganized. The simplest example is to undo the last commit, re-edit some files, and redo the commit. Another simple eample is to undo the last two commits, and commit the changes in those two commits as a single commit. In this case, you would want to have "git reset HEAD^" reset the $GIT_DIR/HEAD to the commit object name of the parent commit of the current commit (i.e. rewinding one commit), leave the index file and the files in the working tree in a state where you can easily make a commit that records a tree that resembles what you have in the current index file and the working tree. The current behaviour is almost OK for this purpose, except that you need to find which files you need to manually run "git add" yourself. They are files that are in the original HEAD commit and not in the commit you are resetting to. The default without the type flag is to do "--mixed", which is the current behaviour. $ git reset [ --hard | --soft | --mixed ] [ <commit-ish> ] A hard reset would be used for 1 and works in this way: (1) remember the set of paths that appear in the current index file (which may even have unmerged entries) and the current $GIT_DIR/HEAD commit. (2) "read-tree --reset" the specified <commit-ish> (default to HEAD), followed by "checkout-cache -f -u -a". (3) remove any files that appear in (1) but not in <commit-ish> from the working tree. (4) backup $GIT_DIR/HEAD to $GIT_DIR/ORIG_HEAD and update $GIT_DIR/HEAD with the specified <commit-ish>. (5) remove leftover $GIT_DIR/MERGE_HEAD A soft reset would be used for 2 and works in this way: (1) Make sure that the index file is merged and we do not have MERGE_HEAD; otherwise it does not make sense to do soft reset. (2) backup $GIT_DIR/HEAD to $GIT_DIR/ORIG_HEAD and update $GIT_DIR/HEAD with the specified <commit-ish>. Note that with the current behaviour, "git diff" is the way to see what could be committed immediately after "git reset". With the "soft reset" described here you would need to say "git diff HEAD" to find that out. I am not sure what mixed reset (the current behaviour) is good for. If nobody comes up with a good use case it may not be a bad idea to remove it. Signed-off-by: NJunio C Hamano <junkio@cox.net>

The 'git show-branches' command turns out to be reasonably useful, but painfully slow. So rewrite it in C, using ideas from merge-base while enhancing it a bit more. - Unlike show-branches, it can take --heads (show me all my heads), --tags (show me all my tags), or --all (both). - It can take --more=<number> to show beyond the merge-base. - It shows the short name for each commit in the extended SHA1 syntax. - It can find merge-base for more than two heads. Examples: $ git show-branch --more=6 HEAD is almost the same as "git log --pretty=oneline --max-count=6". $ git show-branch --merge-base master mhf misc finds the merge base of the three given heads. $ git show-branch master mhf misc shows logs from the top of these three branch heads, up to their common ancestor commit is shown. $ git show-branch --all --more=10 is poor-man's gitk, showing all the tags and heads, and going back 10 commits beyond the merge base of those refs.

The new notation is a short-hand for <name> followed by <num> caret ('^') characters. E.g. "master~4" is the fourth generation ancestor of the current "master" branch head, following the first parents; same as "master^^^^" but a bit more readable.

When "git-diff-script A..B" notation was introduced, it ended up breaking the traditional two revisions notation. [jc: there are other issues with the current "git diff" I would like to address, but they would be left to later rounds. For example, -M and -p flags should not be hardcoded default, and it shouldn't be too hard to rewrite the script without using shell arrays.] Signed-off-by: NJunio C Hamano <junkio@cox.net>

This generalizes the git "glob" string to be a lot more like the git-diff-* pathspecs (but there are still differences: the diff family doesn't do any globbing, and because the diff family always generates the full native pathname, it doesn't have the issue with ".."). It does three things: - it allows multiple matching strings, ie you can do things like git-ls-files arch/i386/ include/asm-i386/ | xargs grep pattern - the "matching" criteria is a combination of "exact path component match" (the same as the git-diff-* family), and "fnmatch()". However, you should be careful with the confusion between the git-ls-files internal globbing and the standard shell globbing, ie git-ls-files fs/*.c does globbing in the shell, and does something totally different from git-ls-files 'fs/*.c' which does the globbing inside git-ls-files. The latter has _one_ pathspec with a wildcard, and will match any .c file anywhere under the fs/ directory, while the former has been expanded by the shell into having _lots_ of pathspec entries, all of which are just in the top-level fs/ subdirectory. They will happily be matched exactly, but we will thus miss all the subdirectories under fs/. As a result, the first one will (on the current kernel) match 55 files, while the second one will match 664 files! - it uses the generic path prefixing, so that ".." and friends at the beginning of the path spec work automatically NOTE! When generating relative pathname output (the default), a pathspec that causes the base to be outside the current working directory will be rejected with an error message like: fatal: git-ls-files: cannot generate relative filenames containing '..' because we do not actually generate ".." in the output. However, the ".." format works fine for the --full-name case: cd arch/i386/kernel git-ls-files --full-name ../mm/ results in arch/i386/mm/Makefile arch/i386/mm/boot_ioremap.c arch/i386/mm/discontig.c arch/i386/mm/extable.c arch/i386/mm/fault.c arch/i386/mm/highmem.c arch/i386/mm/hugetlbpage.c arch/i386/mm/init.c arch/i386/mm/ioremap.c arch/i386/mm/mmap.c arch/i386/mm/pageattr.c arch/i386/mm/pgtable.c Perhaps more commonly, the generic path prefixing means that "." and "./" automatically get simplified and work properly.

This makes git-ls-files work inside a relative directory, and also adds some rudimentary filename globbing support. For example, in the kernel you can now do cd arch/i386 git-ls-files and it will show all files under that subdirectory (and it will have removed the "arch/i386/" prefix unless you give it the "--full-name" option, so that you can feed the result to "xargs grep" or similar). The filename globbing is kind of strange: it does _not_ follow normal globbing rules, although it does look "almost" like a normal file glob (and it uses the POSIX.2 "fnmatch()" function). The glob pattern (there can be only one) is always split into a "directory part" and a "glob part", where the directory part is defined as any full directory path without any '*' or '?' characters. The "glob" part is whatever is left over. For example, when doing git-ls-files 'arch/i386/p*/*.c' the "directory part" is is "arch/i386/", and the "glob part" is "p*/*.c". The directory part will be added to the prefix, and handled efficiently (ie we will not be searching outside of that subdirectory), while the glob part (if anything is left over) will be used to trigger "fnmatch()" matches. This is efficient and very useful, but can result in somewhat non-intuitive behaviour. For example: git-ls-files 'arch/i386/*.[ch]' will find all .c and .h files under arch/i386/, _including_ things in lower subdirectories (ie it will match "arch/i386/kernel/process.c", because "kernel/process.c" will match the "*.c" specifier). Also, while git-ls-files arch/i386/ will show all files under that subdirectory, doing the same without the final slash would try to show the file "i386" under the "arch/" subdirectory, and since there is no such file (even if there is such a _directory_) it will not match anything at all. These semantics may not seem intuitive, but they are actually very practical. In particular, it makes it very simple to do git-ls-files fs/*.c | xargs grep some_pattern and it does what you want.

I think Linus did a cut & paste from an early JIT code while developing the current extended SHA1 notation, and left it there as a courtesy, but the directory does not deserve to be treated any more specially than, say, .git/refs/bisect. If the subdirectories under .git/refs proliferate, we may want to switch to scanning that hierarchy at runtime, instead of the current hard-coded set, although I think that would be overkill.

There are three hooks: - 'pre-commit' is given an opportunity to inspect what is being committed, before we invoke the EDITOR for the commit message; - 'commit-msg' is invoked on the commit log message after the user prepares it; - 'post-commit' is run after a successful commit is made.

After you deleted files from your working tree, automatic git-update-cache used when the "--all" flag is given to "git commit" barfs because it lacks the --remove flag.

In case of a commit with an empty message there is no mandatory empty line between headers and body [jc: This makes --mbox output valid even when the commit message does not have anything but its first line, which the one I wrote botched. One side-effect is that it adds an extra blank line at the end even if it has more than one lines, which will be eaten by the receiving end. As Marco says, this is a stop-gap measure. This script needs to be split into two, one that gets the format specifier and a commit ID to write to its standard output, and another that drives that one reading from rev-list. I'll fix things properly when that happens by rewriting the former part in Perl or something more reasonable than the current shell, sed and grep mishmash.] Signed-off-by: NMarco Costalba <mcostalba@yahoo.it> Signed-off-by: NJunio C Hamano <junkio@cox.net>

These are features requested by Junio. Any plain file under .git/refs whose contents start with 40 hex characters is taken as a reference and displayed like a head but with a light blue background (unless it is in .git/refs/tags or .git/refs/heads, in which case it is displayed as before). There is now a "Reread references" menu item in the File menu which re-reads all the plain files under .git/refs and redisplays any references that have changed.
