[PATCH] Allow file removal when "git commit --all" is used.
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.
It can be argued that this is a feature; people should be
careful and something with a grave consequence like removing
files should be done manually, in which case the current
behaviour may be OK.
The patch is for people who thinks the user who uses the "--all"
flag deserves the danger that comes with the convenience.
[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.]

Display the contents of a tag when the user clicks on it.
This just displays the result of git-cat-file on the tag in the
details pane. If the tag is a "direct" tag (the tag file contains
the SHA1 ID of a commit rather than a tag), we show the tag name
and SHA1 ID.
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.
This makes git-applymbox verify that the index matches the current HEAD
before it starts applying patches.
Otherwise, you might have updated the index with unrelated changes, and
the first patch will commit not just the patch from the mbox, but also any
changes you had in your index.

With --parents, git-rev-list gives us the list of parents on the

the parent: lines in the commit body, since this way we get to

to the glossary. (There is no cache, but an index. Use "object name"
rather than "SHA1". Reorder. Clarify.)

When the graph gets too wide (as defined by the maxwidth variable,
which can be set in ~/.gitk), we can now terminate graph lines with
an arrow pointing downwards, and reintroduce them later with an
arrow pointing upwards when we need them. This makes the graph much
less cluttered on large repositories such as the linux kernel.
Unfortunately this has made it slower; it takes about 10 seconds
user time on the linux-2.6 repository on my machine now, compared
to 6 seconds before. I'll have to work on optimizing that. Also
on the todo list are making the arrow heads active (so if you click
on them you jump to the other end) and improving the placement of
the null entry.
It did not check to see if the working tree was clean and matched
the commit we were starting out as, resulting in the initial rebased
commit including whatever dirty state the working tree has had.
Make sure alternates are carried over from the original repository.
When we create a cheap local clone by pointing at the object databse
of the original repository, we forgot to take the alternates the original
repository might have had into account.
The earlier one to grab output from diff-files --name-only has a grave
bug that when no paths are given it ended up doing the equivalent of
"git-commit --all", which was not what I intended.
[PATCH] Export relative path handling "prefix_path()" function

When running "git commit" with explicit path arguments, allow it to
take directory name. This makes "git commit Documentation/" to commit
everything that is changed under Documentation/ directory.
This corresponds to the -k flag to git format-patch --mbox
option. The option should probably not be used when applying a
real e-mail patch, but is needed when format-patch and applymbox
pair is used for cherrypicking.
Use LF and allow comments in objects/info/alternates file.
Yes, using the same format for the file and the environment variable
was a big mistake. This uses LF as the path separator, and allows
lines that begin with '#' to be comments. ':' is no longer a separator
in objects/info/alternates file.
Introduces --keep-subjects flag to tell it not to munge the
first line of the commit message. Running "git applymbox" on
the output from "git format-patch -m -k" would preserve the
original commit information better this way.
[PATCH] Improve handling of "." and ".." in git-diff-*
This fixes up usage of ".." (without an ending slash) and "." (with or

It also fixes pathspec matching for the case of an empty pathspec, since a
"." in the top-level directory (or enough ".." under subdirectories) will
result in an empty pathspec. We used to not match it against anything, but
it should in fact match everything.

Note that "../xyz" also works, so you can do

[PATCH] Add a bit more links to the commands to the main git(7) page.
There are many programs like git-add not described at all, and the
organization of the list of commands may be suboptimal, but we have to
start somewhere.
Because there is no reason not to, and this makes things a bit
safer when running "git prune".
[jc: I do not necessarily agree with the reasoning of the
original author that it is a good way to keep "git prune" from
stomping on objects to have a symlink that points at .git/refs
of the repository A in the .git/refs of the repository B when
repository A borrows object database from repository B. For one
thing, the object database that everybody borrows objects from
may not even have its own .git/refs hierarchy. Come to think of
it, maybe we should disallow symlink inside .git/refs hierarchy;
we update the files there by creat/rename pair, so having
symlinks would not work anyway when you do anything that would
update them.]
Early versions of git-cvsimport defaulted to using preexisting keyword
expansion settings. This change preserves compatibility with existing cvs
imports and allows new repository migrations to kill keyword expansion.
After exploration of the different -k modes in the cvs protocol, we use -kk
which kills keyword expansion wherever possible. Against the protocol
spec, -ko and -kb will sometimes expand keywords.
Should improve our chances of detecting merges and reduce imported
repository size.

Keep excellent tutorial for using topic branches by Tony Luck
I would eventually like to move this to become a part of the tutorial,
but anyway, this was an excellent post that describes how topic
branches can be used to keep track of local changes.
Often I find myself wanting to do quick branches check when I am

This stupid script shows commits leading to the heads of
interesting branches with indication which ones belong to which
branches, so that fork point is somewhat discernible without
using gitk.

Add cheap local clone '-s' flag to git-clone-script
Using the $GIT_OBJECT_DIRECTORY/info/alternates mechanism,
create a new repository that borrows objects from the original
repository when --shared flag is given in addition to --local.
It is worth pointing out that the "cloned" repository depends on
the original repository, so this should be used only when you
can reasonably trust that the original repository would not
disappear without your knowing.
It was a mistake to use GIT_ALTERNATE_OBJECT_DIRECTORIES
environment variable to specify what alternate object pools to
look for missing objects when working with an object database.
It is not a property of the process running the git commands,
but a property of the object database that is partial and needs
other object pools to complete the set of objects it lacks.
This patch allows you to have $GIT_OBJECT_DIRECTORY/info/alternates
whose contents is in exactly the same format as the environment
variable, to let an object database name alternate object pools
it depends on.
Linus brought up that documentation for many commands have

Not that I have stricter patch submission standard than ordinary
projects, I wanted to have it to make sure people understand
what they are doing when they add their own Signed-off-by line.
As brought up in the discussion which followed a patch to add a
signed-off-by line with the --sign flag to format-patch from
Johannes Schindelin, add --signoff to the git commit command.
Also add --verify to make sure the lines you introduced are
clean, which is more useful in commit but not very much in
format-patch as it was originally implemented, because finding
botches at format-patch time is too late.
This patch renames COPTS to CFLAGS, because it's COPTS that was user
overridable. Also, -Wall is moved there because it's optional. What
was CFLAGS is now ALL_CFLAGS, which users should not override.
Defines are added to DEFINES. Since ALL_CFLAGS is recursively expanded,
it uses the final value of DEFINES.
Implicit rules are made explicit since the implicit rules use CFLAGS
rather than ALL_CFLAGS. I believe that serious projects should not rely
on implicit rules anyway. Percent rules are used because they are used
already and because they don't need the .SUFFIXES target.

[PATCH] Trapping exit in tests, using return for errors
I have noticed that "make test" fails without any explanations when the
"merge" utility is missing. I don't think tests should be silent in
case of failure.
It turned out that the particular test was using "exit" to interrupt the
test in case of an error. This caused the whole test script to exit.
No further tests would be run even if "--immediate" wasn't specified.
No error message was printed.
This patch does following:
All instances of "exit", "exit 1" and "(exit 1)" in tests have been
replaced with "return 1". In fact, "(exit 1)" had no effect.
File descriptor 5 is duplicated from file descriptor 1. This is needed
to print important error messages from tests.
New function test_run_() has been introduced. Any "return" in the test
would merely cause that function to return without skipping calls to
test_failure_() and test_ok_(). The new function also traps "exit" and
treats it like a fatal error (in case somebody reintroduces "exit" in
the tests).
test_expect_failure() and test_expect_success() check both the result of
eval and the return value of test_run_(). If the later is not 0, it's
always a failure because it indicates the the test didn't complete.
