This originally came from Frank Sorenson, but with a bit of rework to
allow future enhancements without changing the external interface for
pack pruning part.

With the '-a' option, all objects in the current repository are packed
into a single pack.  When the '-d' option is given at the same time,
existing packs that were made redundant by this round of repacking are
deleted.

Since we currently have only two repacking strategies, one with '-a'
(everything into one) and the other without '-a' (incrementally pack
only the unpacked ones), the '-d' option is meaningful only when used
with '-a'; it removes the packs existed before we did the "everything

[PATCH] Make .git directory validation code test HEAD

Inspired by a report by Kalle Valo, this changes git-sh-setup-script and
the "setup_git_directory()" function to test that $GIT_DIR/HEAD is a
symlink, since a number of core git features depend on that these days.

We used to allow a regular file there, but git-fsck-cache has been
complaining about that for a while, and anything that uses branches
depends on the HEAD file being a symlink, so let's just encode that as a
fundamental requirement.

Before, a non-symlink HEAD file would appear to work, but have subtle bugs
like not having the HEAD show up as a valid reference (because it wasn't
under "refs"). Now, we will complain loudly, and the user can fix it up
trivially instead of getting strange behaviour.

This also removes the tests for "$GIT_DIR" and "$GIT_OBJECT_DIRECTORY"
being directories, since the other tests will implicitly test for that
anyway (ie the tests for HEAD, refs and 00 would fail).

      - if <remote> is the name of a file under $GIT_DIR/branches/

is the same as giving a single <refspec>
"<remote-name>:refs/heads/<remote>" on the command line, where
<remote-name> is the remote branch name (defaults to HEAD, but

  --revs-only tells it not to output things that are not revisions nor
flags that rev-list would take.
  --no-revs tells it not to output things that are revisions or

  --flags tells it not to output parameters that do not start with
a '-'.
  --no-flags tells it not to output parameters that starts with a '-'.

Introduce "reset type" flag to "git reset"

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.

[PATCH] Add 'git show-branch'.

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.

Linus Torvalds [Mon, 22 Aug 2005 00:27:50 +0000 (17:27 -0700)]
[PATCH] git-ls-files: generalized pathspecs

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.

19 years ago[PATCH] Make "git-ls-files" work in subdirectories
Linus Torvalds [Sun, 21 Aug 2005 19:55:33 +0000 (12:55 -0700)]
[PATCH] Make "git-ls-files" work in subdirectories

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.
