[PATCH] Multi-head fetch.
Traditionally, fetch takes these forms:
$ git fetch <remote>
$ git fetch <remote> <head>
$ git fetch <remote> tag <tag>
This patch updates it to take
$ git fetch <remote> <refspec>...
where:
- A <refspec> of form "<src>:<dst>" is to fetch the objects
needed for the remote ref that matches <src>, and if <dst>
is not empty, store it as a local <dst>.
- "tag" followed by <next> is just an old way of saying
"refs/tags/<next>:refs/tags/<next>"; this mimics the
current behaviour of the third form above and means "fetch
that tag and store it under the same name".
- A single token <refspec> without colon is a shorthand for
"<refspec>:" That is, "fetch that ref but do not store
anywhere".
- when there is no <refspec> specified
- if <remote> is the name of a file under $GIT_DIR/remotes/
(i.e. a new-style shorthand), then it is the same as giving
the <refspec>s listed on Pull: line in that file.
- if <remote> is the name of a file under $GIT_DIR/branches/
(i.e. an old-style shorthand, without trailing path), then it
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
can be overridden by .git/branches/<remote> file having the
URL fragment notation). That is, "fetch that branch head and
store it in refs/heads/<remote>".
- otherwise, it is the same as giving a single <refspec>
that is "HEAD:".

one name per line, with a comment to describe where it came from.

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.

- 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

$ git show-branch master mhf misc
shows logs from the top of these three branch heads, up to their

$ git show-branch --all --more=10

[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

"./" automatically get simplified and work properly.

[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.

generation ancestor of the current "master" branch head,
following the first parents; same as "master^^^^" but a bit more
readable.
This will be used in the updated "git show-branch" command.

There are three hooks:
- 'pre-commit' is given an opportunity to inspect what is

- '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

It can be argued that this is a feature; people should be
careful and something with a grave consequence like removing

behaviour may be OK.

[PATCH] Fix git-format-patch-script to handle empty messages
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.]
