git clean: Don't automatically remove directories when run within subdirectory

When git clean is run from a subdirectory it should follow the normal
policy and only remove directories if they are passed in as a pathspec,
or -d is specified.

The fix is to send len which could be shorter than ent->len because we
have stripped the trailing '/' that read_directory adds. Additionaly
match_one() was modified to allow a name[] that is not NUL terminated.
This allows us to check if the name matched the pathspec exactly
instead of recursively.

git-submodule - possibly use branch name to describe... Mark Levedahl Tue, 15 Apr 2008 02:48:06 +0000 (22:48 -0400)

git-submodule - possibly use branch name to describe a module

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.

bisect: fix bad rev checking in "git bisect good"

It seems that "git bisect good" and "git bisect skip" have never
properly checked arguments that have been passed to them. As soon
as one of them can be parsed as a SHA1, no error or warning would
be given.

This is because 'git rev-parse --revs-only --no-flags "$@"' always
"exit 0" and outputs all the SHA1 it can found from parsing "$@".

This patch fix this by using, for each "bisect good" argument, the
same logic as for the "bisect bad" argument.

While at it, this patch teaches "bisect bad" to give a meaningfull
error message when it is passed more than one argument.

Note that if "git bisect good" or "git bisect skip" is given some
proper revs and then something that is not a proper rev, then the
first proper revs will still have been marked as "good" or "skip".

git-fetch: fix status output when not storing tracking ref

There was code in update_local_ref for handling this case,
but it never actually got called. It assumed that storing in
FETCH_HEAD meant a blank peer_ref name, but we actually have
a NULL peer_ref in this case, so we never even made it to
the update_local_ref function.

On top of that, the display formatting was different from
all of the other cases, probably owing to the fact that
nobody had ever actually seen the output.

This patch harmonizes the output with the other cases and
moves the detection of this case into store_updated_refs,
where we can actually trigger it.

When it checked if a file has the attribute turned on, git-archive would try
to look up the full path -- including the prefix -- in .gitattributes. That's
wrong, as the prefix doesn't need to have any relation to any existing
directories, tracked or not.

attribute export-subst for a file.

test suite: remove useless TERM cruft in "t7005-editor.sh"

In commit 15387e3 (Test suite: reset TERM to its previous value after

value before the "test_done" at the end of "t7005-editor.sh" because
otherwise "test_done" would have printed the test result with a bad TERM
env variable (this resulted in output with no color on konsole).

But since commit c2116a1 (test-lib: fix TERM to dumb for test
repeatability, 2008-03-06), colored output is printed in a subshell with
TERM reset to its original value so the earlier workaround is not needed

Fix "git apply" to correctly enforce "match at the beginning"

An earlier commit 4be6096 (apply --unidiff-zero: loosen sanity checks for
--unidiff=0 patches, 2006-09-17) made match_beginning and match_end
computed incorrectly. If a hunk inserts at the beginning, old position
recorded at the hunk is line 0, and if a hunk changes at the beginning, it
is line 1. The new test added to t4104 exposes that the old code did not
insist on matching at the beginning for a patch to add a line to an empty
file.

An even older 65aadb9 (apply: force matching at the beginning.,
2006-05-24) was equally wrong in that it tried to take hints from the
number of leading context lines, to decide if the hunk must match at the
beginning, but we can just look at the line number in the hunk to decide.

gitk: Fix changing colors through Edit->Preferences

With tcl/tk8.5 the lset command seems to behave differently. When
changing the background color through Edit->Preferences, the changes
are applied, but new dialogs, such as View->New view... barf with

Error: unknown color name "{#ffffff}"

Additionally when closing gitk, and starting it up again, a bad value
has been saved to ~/.gitk, preventing gitk from running properly; it
fails with

Error in startup script: unknown color name "{#ffffff}"
...

This commit fixes the problem by changing the color dialogs to pass
the empty string {} as the list index to choosecolor. This causes
the lset and lindex commands used by choosecolor to use and set the
whole variable (bgcolor, fgcolor or selectbgcolor) rather than
treating them as a 1-element list. Tested with tcl/tk8.4 and 8.5.

Accept git aliases outside a git repositoryJunio C Hamano Tue, 1 Apr 2008 04:33:09 +0000 (21:33 -0700)

Accept git aliases outside a git repository

af05d67 (Always set *nongit_ok in setup_git_directory_gently(),
2008-03-25) had a change from the patch originally submitted that resulted
in disabling aliases outside a git repository.

It turns out that some people used "alias.fubar = diff --color-words" in
$HOME/.gitconfig to use non-index diff (or any command that do not need
git repository) outside git repositories, and this change broke them,
so this resurrects the support for such usage.

filter-branch: Fix renaming a directory in the tree... veillette@yahoo.ca Mon, 31 Mar 2008 07:14:15 +0000 (09:14 +0200)

filter-branch: Fix renaming a directory in the tree-filter

Commit d89c1df (filter-branch: don't use xargs -0, 2008-03-12) replaced a
'ls-files | xargs rm' pipeline by 'git clean'. 'git clean' however does
not recurse and remove directories by default.

Now, consider a tree-filter that renames a directory.

1. For the first commit everything works as expected

2. Then filter-branch checks out the files for the next commit. This
leaves the new directory behind because there is no real "branch
switching" involved that would notice that the directory can be
removed.

3. Then filter-branch invokes 'git clean' to remove exactly those
left-overs. But here it does not remove the directory.

4. The next tree-filter does not work as expected because there already
exists a directory with the new name.

Just add -d to 'git clean', so that empty directories are removed.

filter-branch: Test renaming directories in a tree-filter

This test currently fails.

If b is a directory then 'mv a b' is not a plain "rename", but really a
"move", so we must also test that the directory does not exist with the
old name in the directory with the new name.

There's also some cleanup in the corresponding "rename file" test to avoid
spurious shell syntax errors and "ambigous ref" error from 'git show' (but
these should show up only if the test would fail anyway). Plus we also
test for the non-existence of the old file.

Since nearly its birth, git's tags have included a "tagger" field which

But, this field was only loosely tested by git-mktag. Provide some thorough
testing for this field and also ensure that the tag header is separated
from the tag body by an empty line to reduce the convenience of creating

diff-index: careful when inspecting work tree items

Earlier, if you changed a staged path into a directory in the work tree,
we happily ran lstat(2) on it and found that it exists, and declared that
the user changed it to a gitlink.

This is wrong for two reasons:

(1) It may be a directory, but it may not be a submodule, and in the
latter case, the change we need to report is "the blob at the path
has disappeared". We need to check with resolve_gitlink_ref() to be
consistent with what "git add" and "git update-index --add" does.

(2) lstat(2) may have succeeded only because a leading component of the
path was turned into a symbolic link that points at something that
exists in the work tree. In such a case, the path itself does not
exist anymore, as far as the index is concerned.

This fixes these breakages in diff-index that the previous patch has
exposed.

Tracked remote branches
maint master mob
Local branch pushed with 'git push'
