77e4e8bd9b gitweb: Add test t9500 for gitweb (as standalone script)
This test runs gitweb (git web interface) as CGI script from
commandline, and checks that it would not write any errors
or warnings to log.

af9b54bb2c Use $Id$ as the ident attribute keyword rather than $ident$ to be consistent with other VCSs
$Id$ is present already in SVN and CVS; it would mean that people
converting their existing repositories won't have to make any changes to
the source files should they want to make use of the ident attribute.

Given that it's a feature that's meant to calm those very people, it
seems obtuse to make them edit every file just to make use of it.

I think that bzr uses $Id$; Mercurial has examples hooks for $Id$;
monotone has $Id$ on its wishlist.  I can't think of a good reason not
to stick with the de-facto standard and call ours $Id$ instead of
$ident$.

4a1bb4c3f8 git-svn: don't attempt to minimize URLs by default
For tracking branches and tags, git-svn prefers to connect
to the root of the repository or at least the level that
houses branches and tags as well as trunk.  However, users
that are accustomed to tracking a single directory have
no use for this feature.

As pointed out by Junio, users may not have permissions to
connect to connect to a higher-level path in the repository.

While the current minimize_url() function detects lack of
permissions to certain paths _after_ successful logins, it
cannot effectively determine if it is trying to access a
login-only portion of a repo when the user expects to
connect to a part where anonymous access is allowed.

For people used to the git-svnimport switches of
--trunk, --tags, --branches, they'll already pass the
repository root (or root+subdirectory), so minimize URL
isn't of too much use to them, either.

For people *not* used to git-svnimport, git-svn also
supports:

 git svn init --minimize-url \
  --trunk http://repository-root/foo/trunk \
  --branches http://repository-root/foo/branches \
  --tags http://repository-root/foo/tags

And this is where the new --minimize-url command-line switch
comes in to allow for this behavior to continue working.

a25907dac4 t9400: Use the repository config and nothing else.
git-cvsserver has a bug in its configuration file output parser
that makes it choke if the configuration has these:

        [diff]
                color = auto
        [diff.color]
                whitespace = blue reverse

This needs to be fixed, but thanks to that bug, a separate bug
in t9400 test script was discovered.  The test discarded
GIT_CONFIG instead of pointing at the proper one to be used in
the exoprted repository.  This allowed user's .gitconfig and (if
exists) systemwide /etc/gitconfig to affect the outcome of the
test, which is a big no-no.

The patch fixes the problem in the test.  Fixing the
git-cvsserver's configuration parser is left as an exercise to
motivated volunteers ;-)

16a4c6176a read-tree -m -u: avoid getting confused by intermediate symlinks.
When switching from a branch with both x86_64/boot/Makefile and
i386/boot/Makefile to another branch that has x86_64/boot as a
symlink pointing at ../i386/boot, the code incorrectly removed
i386/boot/Makefile.

This was because we first removed everything under x86_64/boot
to make room to create a symbolic link x86_64/boot, then removed
x86_64/boot/Makefile which no longer exists but now is pointing
at i386/boot/Makefile, thanks to the symlink we just created.

This fixes it by using the has_symlink_leading_path() function
introduced previously for git-apply in the checkout codepath.
Earlier, "git checkout" was broken in t4122 test due to this
bug, and the test had an extra "git reset --hard" as a
workaround, which is removed because it is not needed anymore.

64cab59159 apply: do not get confused by symlinks in the middle
HPA noticed that git-rebase fails when changes involve symlinks
in the middle of the hierarchy.  Consider:

 * The tree state before the patch is applied has arch/x86_64/boot
   as a symlink pointing at ../i386/boot/

 * The patch tries to remove arch/x86_64/boot symlink, and
   create bunch of files there: .gitignore, Makefile, etc.

git-apply tries to be careful while applying patches; it never
touches the working tree until it is convinced that the patch
would apply cleanly.  One of the check it does is that when it
knows a path is going to be created by the patch, it runs
lstat() on the path to make sure it does not exist.

This leads to a false alarm.  Because we do not touch the
working tree before all the check passes, when we try to make
sure that arch/x86_64/boot/.gitignore does not exist yet, we
haven't removed the arch/x86_64/boot symlink.  The lstat() check
ends up seeing arch/i386/boot/.gitignore through the
yet-to-be-removed symlink, and says "Hey, you already have a
file there, but what you fed me is a patch to create a new
file. I am not going to clobber what you have in the working
tree."

We have similar checks to see a file we are going to modify does
exist and match the preimage of the diff, which is done by
directly opening and reading the file.

For a file we are going to delete, we make sure that it does
exist and matches what is going to be removed (a removal patch
records the full preimage, so we check what you have in your
working tree matches it in full -- otherwise we would risk
losing your local changes), which again is done by directly
opening and reading the file.

These checks need to be adjusted so that they are not fooled by
symlinks in the middle.

 - To make sure something does not exist, first lstat().  If it
   does not exist, it does not, so be happy.  If it _does_, we
   might be getting fooled by a symlink in the middle, so break
   leading paths and see if there are symlinks involved.  When
   we are checking for a path a/b/c/d, if any of a, a/b, a/b/c
   is a symlink, then a/b/c/d does _NOT_ exist, for the purpose
   of our test.

   This would fix this particular case you saw, and would not
   add extra overhead in the usual case.

 - To make sure something already exists, first lstat().  If it
   does not exist, barf (up to this, we already do).  Even if it
   does seem to exist, we might be getting fooled by a symlink
   in the middle, so make sure leading paths are not symlinks.

   This would make the normal codepath much more expensive for
   deep trees, which is a bit worrisome.

This patch implements the first side of the check "making sure
it does not exist".  The latter "making sure it exists" check is
not done yet, so applying the patch in reverse would still
fail, but we have to start from somewhere.

aa4ed402c9 Add 'filter' attribute and external filter driver definition.
The interface is similar to the custom low-level merge drivers.

First you configure your filter driver by defining 'filter.<name>.*'
variables in the configuration.

	filter.<name>.clean	filter command to run upon checkin
	filter.<name>.smudge	filter command to run upon checkout

Then you assign filter attribute to each path, whose name
matches the custom filter driver's name.

Example:

	(in .gitattributes)
	*.c	filter=indent

	(in config)
	[filter "indent"]
		clean = indent
		smudge = cat

c7f34c180b dir.c(common_prefix): Fix two bugs
The function common_prefix() is used to find the common subdirectory of
a couple of pathnames. When checking if the next pathname matches up with
the prefix, it incorrectly checked the whole path, not just the prefix
(including the slash). Thus, the expensive part of the loop was executed
always.

The other bug is more serious: if the first and the last pathname in the
list have a longer common prefix than the common prefix for _all_ pathnames
in the list, the longer one would be chosen. This bug was probably hidden
by the fact that bash's wildcard expansion sorts the results, and the code
just so happens to work with sorted input.

f1af60bdba Support 'diff=pgm' attribute
This enhances the attributes mechanism so that external programs
meant for existing GIT_EXTERNAL_DIFF interface can be specifed
per path.

To configure such a custom diff driver, first define a custom
diff driver in the configuration:

	[diff "my-c-diff"]
		command = <<your command string comes here>>

Then mark the paths that you want to use this custom driver
using the attribute mechanism.

	*.c	diff=my-c-diff

The intent of this separation is that the attribute mechanism is
used for specifying the type of the contents, while the
configuration mechanism is used to define what needs to be done
to that type of the contents, which would be specific to both
platform and personal taste.

163b959194 Update 'crlf' attribute semantics.
This updates the semantics of 'crlf' so that .gitattributes file
can say "this is text, even though it may look funny".

Setting the `crlf` attribute on a path is meant to mark the path
as a "text" file.  'core.autocrlf' conversion takes place
without guessing the content type by inspection.

Unsetting the `crlf` attribute on a path is meant to mark the
path as a "binary" file.  The path never goes through line
endings conversion upon checkin/checkout.

Unspecified `crlf` attribute tells git to apply the
`core.autocrlf` conversion when the file content looks like
text.

Setting the `crlf` attribut to string value "input" is similar
to setting the attribute to `true`, but also forces git to act
as if `core.autocrlf` is set to `input` for the path.

1c3e5c4ebc Tests for core subproject support
The following tests available:

- create subprojects: create a directory in the superproject,
  initialize a git repo in it, and try adding it in super project.
  Make a commit in superproject

- check if fsck ignores the subprojects: it just should give no errors

- check if commit in a subproject detected: make a commit in
  subproject, git-diff-files in superproject should detect it

- check if a changed subproject HEAD can be committed: try
  "git-commit -a" in superproject. It should commit changed
  HEAD of a subproject

- check if diff-index works for subproject elements: compare the index
  (changed by previuos tests) with the initial commit (which created
  two subprojects). Should show a change for the recently changed subproject

- check if diff-tree works for subproject elements: do the same, just use
  git-diff-tree. This test is somewhat redundant, I just added it for
  completeness (diff, diff-files, and diff-index are already used)

- check if git diff works for subproject elements: try to limit
  the diff for the name of a subproject in superproject:
     git diff HEAD^ HEAD -- subproject

- check if clone works: try a clone of superproject and compare
  "git ls-files -s" output in superproject and cloned repo

- removing and adding subproject: rename test. Currently implemented
  as "git-update-index --force-remove", "mv" and "git-add".

- checkout in superproject: try to checkout the initial commit

0afa7644f2 Fix overwriting of files when applying contextually independent diffs
Noticed by applying two diffs of different contexts to the same file.

The check for existence of a file was wrong: the test assumed it was
a directory and reset the errno (twice: directly and by calling
lstat). So if an entry existed and was _not_ a directory no attempt
was made to rename into it, because the errno (expected by renaming
code) was already reset to 0. This resulted in error:

    fatal: unable to write file file mode 100644

For Linux, removing "errno = 0" is enough, as lstat wont modify errno
if it was successful. The behavior should not be depended upon,
though, so modify the "if" as well.

The test simulates this situation.

153920da5b Custom low-level merge driver: change the configuration scheme.
This changes the configuration syntax for defining a low-level
merge driver to be:

	[merge "<<drivername>>"]
		driver = "<<command line>>"
		name = "<<driver description>>"

which is much nicer to read and is extensible.  Credit goes to
Martin Waitz and Linus.

In addition, when we use an external low-level merge driver, it
is reported as an extra output from merge-recursive, using the
value of merge.<<drivername>.name variable.

The demonstration in t6026 has also been updated.

f3ef6b6bbe Custom low-level merge driver support.
This allows users to specify custom low-level merge driver per
path, using the attributes mechanism.  Just like you can specify
one of built-in "text", "binary", "union" low-level merge
drivers by saying:

	*		merge=text
	.gitignore	merge=union
	*.jpg		merge=binary

pick a name of your favorite merge driver, and assign it as the
value of the 'merge' attribute.

A custom low-level merge driver is defined via the config
mechanism.  This patch introduces 'merge.driver', a multi-valued
configuration.  Its value is the name (i.e. the one you use as
the value of 'merge' attribute) followed by a command line
specification.  The command line can contain %O, %A, and %B to
be interpolated with the names of temporary files that hold the
common ancestor version, the version from your branch, and the
version from the other branch, and the resulting command is
spawned.

The low-level merge driver is expected to update the temporary
file for your branch (i.e. %A) with the result and exit with
status 0 for a clean merge, and non-zero status for a conflicted
merge.

A new test in t6026 demonstrates a sample usage.

47579efc00 Add a demonstration/test of customized merge.
This demonstrates how the new low-level per-path merge backends,
union and ours, work, and shows how they are controlled by the
gitattribute mechanism.

b9849a1ab6 Make sure quickfetch is not fooled with a previous, incomplete fetch.
This updates git-rev-list --objects to be a bit more careful
when listing a blob object to make sure the blob actually
exists, and uses it to make sure the quick-fetch optimization we
introduced earlier is not fooled by a previous incomplete fetch.

The quick-fetch optimization works by running this command:

	git rev-list --objects <<commit-list>> --not --all

where <<commit-list>> is a list of commits that we are going to
fetch from the other side.  If there is any object missing to
complete the <<commit-list>>, the rev-list would fail and die
(say, the commit was in our repository, but its tree wasn't --
then it will barf while trying to list the blobs the tree
contains because it cannot read that tree).

Usually we do not have the objects (otherwise why would we
fetching?), but in one important special case we do: when the
remote repository is used as an alternate object store
(i.e. pointed by .git/objects/info/alternates).  We could check
.git/objects/info/alternates to see if the remote we are
interacting with is one of them (or is used as an alternate,
recursively, by one of them), but that check is more cumbersome
than it is worth.

The above check however did not catch missing blob, because
object listing code did not read nor check blob objects, knowing
that blobs do not contain any further references to other
objects.  This commit fixes it with practically unmeasurable
overhead.

I've benched this with

	git rev-list --objects --all >/dev/null

in the kernel repository, with three different implementations
of the "check-blob".

 - Checking with has_sha1_file() has negligible (unmeasurable)
   performance penalty.

 - Checking with sha1_object_info() makes it somewhat slower,
   perhaps by 5%.

 - Checking with read_sha1_file() to cause a fully re-validation
   is prohibitively expensive (about 4 times as much runtime).

In my original patch, I had this as a command line option, but
the overhead is small enough that it is not really worth it.
