12f0a5ea7d Fix 'git cvsexportcommit -w $cvsdir ...' when used with relative $GIT_DIR
When using the '-w $cvsdir' option to cvsexportcommit, it will chdir into
$cvsdir before executing several other git commands. If $GIT_DIR is set to
a relative path (e.g. '.'), the git commands executed by cvsexportcommit
will naturally fail.

Therefore, ensure that $GIT_DIR is absolute before the chdir to $cvsdir.

b560707a1d Add tests for filesystem challenges (case and unicode normalization)
Git has difficulties on file systems that do not properly
distinguish case or modify filenames in unexpected ways.  The two
major examples are Windows and Mac OS X.  Both systems preserve
case of file names but do not distinguish between filenames that
differ only by case.  Simple operations such as "git mv" or
"git merge" can fail unexpectedly.  In addition, Mac OS X normalizes
unicode, which make git's life even harder.

This commit adds tests that currently fail but should pass if
file system as decribed above are fully supported.  The test need
to be run on Windows and Mac X as they already pass on Linux.

Mitch Tishmack is the original author of the tests for unicode
normalization.

[jc: fixed-up so that it will use test_expect_success to test
on sanely behaving filesystems.]

55029ae4da Add support for url aliases in config files
This allows users with different preferences for access methods to the
same remote repositories to rewrite each other's URLs by pattern
matching across a large set of similiarly set up repositories to each
get the desired access.

For example, if you don't have a kernel.org account, you might want
settings like:

[url "git://git.kernel.org/pub/"]
      insteadOf = master.kernel.org:/pub

Then, if you give git a URL like:

  master.kernel.org:/pub/scm/linux/kernel/git/linville/wireless-2.6.git

it will act like you gave it:

  git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-2.6.git

and you can cut-and-paste pull requests in email without fixing them
by hand, for example.

b577bb925e Eliminate confusing "won't bisect on seeked tree" failure
This error message is very confusing---it doesn't tell the user
anything about how to fix the situation. And the actual fix
for the situation ("git bisect reset") does a checkout of a
potentially random branch, (compared to what the user wants to
be on for the bisect she is starting).

The simplest way to eliminate the confusion is to just make
"git bisect start" do the cleanup itself. There's no significant
loss of safety here since we already have a general safety in
the form of the reflog.

Note: We preserve the warning for any cogito users. We do this
by switching from .git/head-name to .git/BISECT_START for the
extra state, (which is a more descriptive name anyway).

8a2f5e5b03 hash-object: cleanup handling of command line options
git hash-object used to process the --stdin command line argument
before reading subsequent arguments.  This caused 'git hash-object
--stdin -w' to fail to actually write the object into the
database, while '-w --stdin' properly did.  Now git hash-object
first reads all arguments, and then processes them.

This regresses one insane use case.  git hash-object used to allow
multiple --stdin arguments on the command line:

   $ git hash-object --stdin --stdin
     foo
     ^D
     bar
     ^D

Now git hash-object errors out if --stdin is given more than once.

5274ba6907 git-clone.sh: properly configure remote even if remote's head is dangling
When cloning a remote repository which's HEAD refers to a nonexistent
ref, git-clone cloned all existing refs, but failed to write the
configuration for 'remote'.  Now it detects the dangling remote HEAD,
refuses to checkout any local branch since HEAD refers to nowhere, but
properly writes the configuration for 'remote', so that subsequent
'git fetch's don't fail.

9f0ea7e828 Resolve value supplied for no-colon push refspecs
When pushing a refspec like "HEAD", we used to treat it as
"HEAD:HEAD", which didn't work without rewriting. Instead, we should
resolve the ref. If it's a symref, further require it to point to a
branch, to avoid doing anything especially unexpected. Also remove the
rewriting previously added in builtin-push.

Since the code for "HEAD" uses the regular refspec parsing, it
automatically handles "+HEAD" without anything special.

[jc: added a further test to make sure that "remote.*.push = HEAD" works]

fef3a7cc55 cvsexportcommit: be graceful when "cvs status" reorders the arguments
In my use cases, "cvs status" sometimes reordered the passed filenames,
which often led to a misdetection of a dirty state (when it was in
reality a clean state).

I finally tracked it down to two filenames having the same basename.

So no longer trust the order of the results blindly, but actually check
the file name.

Since "cvs status" only returns the basename (and the complete path on the
server which is useless for our purposes), run "cvs status" several times
with lists consisting of files with unique (chomped) basenames.

Be a bit clever about new files: these are reported as "no file <blabla>",
so in order to discern it from existing files, prepend "no file " to the
basename.

In other words, one call to "cvs status" will not ask for two files
"blabla" (which does not yet exist) and "no file blabla" (which exists).

This patch makes cvsexportcommit slightly slower, when the list of changed
files has non-unique basenames, but at least it is accurate now.

9ed36cfa35 branch: optionally setup branch.*.merge from upstream local branches
"git branch" and "git checkout -b" now honor --track option even when
the upstream branch is local.  Previously --track was silently ignored
when forking from a local branch.  Also the command did not error out
when --track was explicitly asked for but the forked point specified
was not an existing branch (i.e. when there is no way to set up the
tracking configuration), but now it correctly does.

The configuration setting branch.autosetupmerge can now be set to
"always", which is equivalent to using --track from the command line.
Setting branch.autosetupmerge to "true" will retain the former behavior
of only setting up branch.*.merge for remote upstream branches.

Includes test cases for the new functionality.

ee95ec5d58 xdl_merge(): introduce XDL_MERGE_ZEALOUS_ALNUM
When a merge conflicts, there are often common lines that are not really
common, such as empty lines or lines containing a single curly bracket.

With XDL_MERGE_ZEALOUS_ALNUM, we use the following heuristics: when a
hunk does not contain any letters or digits, it is treated as conflicting.

In other words, a conflict which used to look like this:

	<<<<<<<
					a = 1;
	=======
					output();
	>>>>>>>
				}
			}
		}

	<<<<<<<
		output();
	=======
		b = 1;
	>>>>>>>

will look like this with ZEALOUS_ALNUM:

	<<<<<<<
					a = 1;
				}
			}
		}

		output();
	=======
					output();
				}
			}
		}

		b = 1;
	>>>>>>>

To demonstrate this, git-merge-file has been switched from
XDL_MERGE_ZEALOUS to XDL_MERGE_ZEALOUS_ALNUM.

f407f14dea xdl_merge(): make XDL_MERGE_ZEALOUS output simpler
When a merge conflicts, there are often less than three common lines
between two conflicting regions.

Since a conflict takes up as many lines as are conflicting, plus three
lines for the commit markers,  the output will be shorter (and thus,
simpler) in this case, if the common lines will be merged into the
conflicting regions.

This patch merges up to three common lines into the conflicts.

For example, what looked like this before this patch:

	<<<<<<<
	if (a == 1)
	=======
	if (a != 0)
	>>>>>>>
	{
		int i;
	<<<<<<<
		a = 0;
	=======
		a = !a;
	>>>>>>>

will now look like this:

	<<<<<<<
	if (a == 1)
	{
		int i;
		a = 0;
	=======
	if (a != 0)
	{
		int i;
		a = !a;
	>>>>>>>

782c2d65c2 Build in checkout
The only differences in behavior should be:

 - git checkout -m with non-trivial merging won't print out
   merge-recursive messages (see the change in t7201-co.sh)

 - git checkout -- paths... will give a sensible error message if
   HEAD is invalid as a commit.

 - some intermediate states which were written to disk in the shell
   version (in particular, index states) are only kept in memory in
   this version, and therefore these can no longer be revealed by
   later write operations becoming impossible.

 - when we change branches, we discard MERGE_MSG, SQUASH_MSG, and
   rr-cache/MERGE_RR, like reset always has.

I'm not 100% sure I got the merge recursive setup exactly right; the
base for a non-trivial merge in the shell code doesn't seem
theoretically justified to me, but I tried to match it anyway, and the
tests all pass this way.

Other than these items, the results should be identical to the shell
version, so far as I can tell.

18bc76164d add--interactive: handle initial commit better
There were several points where we looked at the HEAD
commit; for initial commits, this is meaningless. So instead
we:

  - show staged status data as a diff against the empty tree
    instead of HEAD
  - show file diffs as creation events
  - use "git rm --cached" to revert instead of going back to
    the HEAD commit

We magically reference the empty tree to implement this.

959ba670ad commit: discard index after setting up partial commit
There may still be some entries from the original index that
should be discarded before we show the status. In
particular, if a file was added in the index but not
included in the partial commit, it would still show up in
the status listing as staged for commit.

Ultimately the correct fix is to keep the two states in
separate index_state variables. Then we can avoid having
to reload the cache from the temporary file altogether, and
just point wt_status_print at the correct index.

8464010f97 Make git prune remove temporary packs that look like write failures
Write errors when repacking (eg, due to out-of-space conditions)
can leave temporary packs (and possibly other files beginning
with "tmp_") lying around which no existing
codepath removes and which aren't obvious to the casual user.
These can also be multi-megabyte files wasting noticeable space.
Unfortunately there's no way to definitely tell in builtin-prune
that a tmp_ file is not being used by a concurrent process,
such as a fetch. However, it is documented that pruning should
only be done on a quiet repository and --expire is honoured
(using code from Johannes Schindelin, along with a test case
he wrote) so that its safety is the same as that of loose
object pruning.

Since they might be signs of a problem (unlike orphaned loose
objects) the names of any removed files are printed.

8bfa6bd647 fix config reading in tests
Previously, we set the GIT_CONFIG environment variable in
our tests so that only that file was read. However, setting
it to a static value is not correct, since we are not
necessarily always in the same directory; instead, we want
the usual git config file lookup to happen.

To do this, we stop setting GIT_CONFIG, which means that we
must now suppress the reading of the system-wide and user
configs.

This exposes an incorrect test in t1500, which is also
fixed (the incorrect test worked because we were failing to
read the core.bare value from the config file, since the
GIT_CONFIG variable was pointing us to the wrong file).

21e5ad50fc safecrlf: Add mechanism to warn about irreversible crlf conversions
CRLF conversion bears a slight chance of corrupting data.
autocrlf=true will convert CRLF to LF during commit and LF to
CRLF during checkout.  A file that contains a mixture of LF and
CRLF before the commit cannot be recreated by git.  For text
files this is the right thing to do: it corrects line endings
such that we have only LF line endings in the repository.
But for binary files that are accidentally classified as text the
conversion can corrupt data.

If you recognize such corruption early you can easily fix it by
setting the conversion type explicitly in .gitattributes.  Right
after committing you still have the original file in your work
tree and this file is not yet corrupted.  You can explicitly tell
git that this file is binary and git will handle the file
appropriately.

Unfortunately, the desired effect of cleaning up text files with
mixed line endings and the undesired effect of corrupting binary
files cannot be distinguished.  In both cases CRLFs are removed
in an irreversible way.  For text files this is the right thing
to do because CRLFs are line endings, while for binary files
converting CRLFs corrupts data.

This patch adds a mechanism that can either warn the user about
an irreversible conversion or can even refuse to convert.  The
mechanism is controlled by the variable core.safecrlf, with the
following values:

 - false: disable safecrlf mechanism
 - warn: warn about irreversible conversions
 - true: refuse irreversible conversions

The default is to warn.  Users are only affected by this default
if core.autocrlf is set.  But the current default of git is to
leave core.autocrlf unset, so users will not see warnings unless
they deliberately chose to activate the autocrlf mechanism.

The safecrlf mechanism's details depend on the git command.  The
general principles when safecrlf is active (not false) are:

 - we warn/error out if files in the work tree can modified in an
   irreversible way without giving the user a chance to backup the
   original file.

 - for read-only operations that do not modify files in the work tree
   we do not not print annoying warnings.

There are exceptions.  Even though...

 - "git add" itself does not touch the files in the work tree, the
   next checkout would, so the safety triggers;

 - "git apply" to update a text file with a patch does touch the files
   in the work tree, but the operation is about text files and CRLF
   conversion is about fixing the line ending inconsistencies, so the
   safety does not trigger;

 - "git diff" itself does not touch the files in the work tree, it is
   often run to inspect the changes you intend to next "git add".  To
   catch potential problems early, safety triggers.

The concept of a safety check was originally proposed in a similar
way by Linus Torvalds.  Thanks to Dimitry Potapov for insisting
on getting the naked LF/autocrlf=true case right.

8089c85bcb git-commit: add a prepare-commit-msg hook
The prepare-commit-msg hook is run whenever a "fresh" commit message
is prepared, just before it is shown in the editor (if it is).
Its purpose is to modify the commit message in-place.

It takes one to three parameters.  The first is the name of the file that
the commit log message.  The second is the source of the commit message,
and can be: "message" (if a -m or -F option was given); "template" (if a
-t option was given or the configuration option commit.template is set);
"merge" (if the commit is a merge or a .git/MERGE_MSG file exists);
"squash" (if a .git/SQUASH_MSG file exists); or "commit", followed by
a commit SHA1 as the third parameter (if a -c, -C or --amend option
was given).

If its exit status is non-zero, git-commit will abort.  The hook is
not suppressed by the --no-verify option, so it should not be used
as a replacement for the pre-commit hook.

The sample prepare-commit-msg comments out the `Conflicts:` part of
a merge's commit message; other examples are commented out, including
adding a Signed-off-by line at the bottom of the commit messsage,
that the user can then edit or discard altogether.

d6b8fc303b gitignore(5): Allow "foo/" in ignore list to match directory "foo"
A pattern "foo/" in the exclude list did not match directory
"foo", but a pattern "foo" did.  This attempts to extend the
exclude mechanism so that it would while not matching a regular
file or a symbolic link "foo".  In order to differentiate a
directory and non directory, this passes down the type of path
being checked to excluded() function.

A downside is that the recursive directory walk may need to run
lstat(2) more often on systems whose "struct dirent" do not give
the type of the entry; earlier it did not have to do so for an
excluded path, but we now need to figure out if a path is a
directory before deciding to exclude it.  This is especially bad
because an idea similar to the earlier CE_UPTODATE optimization
to reduce number of lstat(2) calls would by definition not apply
to the codepaths involved, as (1) directories will not be
registered in the index, and (2) excluded paths will not be in
the index anyway.

An incorrect command "git mv subdir /outer/space" threw the

/outer/space/subdir/ would be outside of the repository.  The
error checking is backwards.

This fixes the issue by being careful about use of the return

d089ebaad5 setup: sanitize absolute and funny paths in get_pathspec()
The prefix_path() function called from get_pathspec() is
responsible for translating list of user-supplied pathspecs to
list of pathspecs that is relative to the root of the work
tree.  When working inside a subdirectory, the user-supplied
pathspecs are taken to be relative to the current subdirectory.

Among special path components in pathspecs, we used to accept
and interpret only "." ("the directory", meaning a no-op) and
".."  ("up one level") at the beginning.  Everything else was
passed through as-is.

For example, if you are in Documentation/ directory of the
project, you can name Documentation/howto/maintain-git.txt as:

    howto/maintain-git.txt
    ../Documentation/howto/maitain-git.txt
    ../././Documentation/howto/maitain-git.txt

but not as:

    howto/./maintain-git.txt
    $(pwd)/howto/maintain-git.txt

This patch updates prefix_path() in several ways:

 - If the pathspec is not absolute, prefix (i.e. the current
   subdirectory relative to the root of the work tree, with
   terminating slash, if not empty) and the pathspec is
   concatenated first and used in the next step.  Otherwise,
   that absolute pathspec is used in the next step.

 - Then special path components "." (no-op) and ".." (up one
   level) are interpreted to simplify the path.  It is an error
   to have too many ".." to cause the intermediate result to
   step outside of the input to this step.

 - If the original pathspec was not absolute, the result from
   the previous step is the resulting "sanitized" pathspec.
   Otherwise, the result from the previous step is still
   absolute, and it is an error if it does not begin with the
   directory that corresponds to the root of the work tree.  The
   directory is stripped away from the result and is returned.

 - In any case, the resulting pathspec in the array
   get_pathspec() returns omit the ones that caused errors.

With this patch, the last two examples also behave as expected.

b2979ff599 core.whitespace: cr-at-eol
This new error mode allows a line to have a carriage return at the
end of the line when checking and fixing trailing whitespace errors.

Some people like to keep CRLF line ending recorded in the repository,
and still want to take advantage of the automated trailing whitespace
stripping.  We still show ^M in the diff output piped to "less" to
remind them that they do have the CR at the end, but these carriage
return characters at the end are no longer flagged as errors.

c1beba5b47 git-apply --whitespace=fix: fix whitespace fuzz introduced by previous run
When you have more than one patch series, an earlier one of which
tries to introduce whitespace breakages and a later one of which
has such a new line in its context, "git-apply --whitespace=fix"
will apply and fix the whitespace breakages in the earlier one,
making the resulting file not to match the context of the later
patch.

A short demonstration is in the new test, t4125.

For example, suppose the first patch is:

    diff a/hello.txt b/hello.txt
    --- a/hello.txt
    +++ b/hello.txt
    @@ -20,3 +20,3 @@
     Hello world.$
    -How Are you$
    -Today?$
    +How are you $
    +today? $

to fix broken case in the string, but it introduces unwanted
trailing whitespaces to the result (pretend you are looking at
"cat -e" output of the patch --- '$' signs are not in the patch
but are shown to make the EOL stand out).  And the second patch
is to change the wording of the greeting further:

    diff a/hello.txt b/hello.txt
    --- a/hello.txt
    +++ b/hello.txt
    @@ -18,5 +18,5 @@
     Greetings $

    -Hello world.$
    +Hello, everybody. $
     How are you $
    -today? $
    +these days? $

If you apply the first one with --whitespace=fix, you will get
this as the result:

    Hello world.$
    How are you$
    today?$

and this does not match the preimage of the second patch, which
demands extra whitespace after "How are you" and "today?".

This series is about teaching "git apply --whitespace=fix" to
cope with this situation better.  If the patch does not apply,
it rewrites the second patch like this and retries:

    diff a/hello.txt b/hello.txt
    --- a/hello.txt
    +++ b/hello.txt
    @@ -18,5 +18,5 @@
     Greetings$

    -Hello world.$
    +Hello, everybody.$
     How are you$
    -today?$
    +these days?$

This is done by rewriting the preimage lines in the hunk
(i.e. the lines that begin with ' ' or '-'), using the same
whitespace fixing rules as it is using to apply the patches, so
that it can notice what it did to the previous ones in the
series.

A careful reader may notice that the first patch in the example
did not touch the "Greetings" line, so the trailing whitespace
that is in the original preimage of the second patch is not from
the series.  Is rewriting this context line a problem?

If you think about it, you will realize that the reason for the
difference is because the submitter's tree was based on an
earlier version of the file that had whitespaces wrong on that
"Greetings" line, and the change that introduced the "Greetings"
line was added independently of this two-patch series to our
tree already with an earlier "git apply --whitespace=fix".

So it may appear this logic is rewriting too much, it is not
so.  It is just rewriting what we would have rewritten in the
past.

991c3dc79f known breakage: revision range computation with clock skew
This is the absolute minimum (and reliable) reproduction recipe
to demonstrate that revision range in a history with clock skew
sometimes fails to mark UNINTERESTING commit in topologically
early parts of the history.

The history looks like this:

	o---o---o---o
	one         four

but one has the largest timestamp.  "git rev-list four..one"
fails to notice that "one" should not be emitted.

41ac414ea2 Sane use of test_expect_failure
Originally, test_expect_failure was designed to be the opposite
of test_expect_success, but this was a bad decision.  Most tests
run a series of commands that leads to the single command that
needs to be tested, like this:

    test_expect_{success,failure} 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        what is to be tested
    '

And expecting a failure exit from the whole sequence misses the
point of writing tests.  Your setup$N that are supposed to
succeed may have failed without even reaching what you are
trying to test.  The only valid use of test_expect_failure is to
check a trivial single command that is expected to fail, which
is a minority in tests of Porcelain-ish commands.

This large-ish patch rewrites all uses of test_expect_failure to
use test_expect_success and rewrites the condition of what is
tested, like this:

    test_expect_success 'test title' '
	setup1 &&
        setup2 &&
        setup3 &&
        ! this command should fail
    '

test_expect_failure is redefined to serve as a reminder that
that test *should* succeed but due to a known breakage in git it
currently does not pass.  So if git-foo command should create a
file 'bar' but you discovered a bug that it doesn't, you can
write a test like this:

    test_expect_failure 'git-foo should create bar' '
        rm -f bar &&
        git foo &&
        test -f bar
    '

This construct acts similar to test_expect_success, but instead
of reporting "ok/FAIL" like test_expect_success does, the
outcome is reported as "FIXED/still broken".

733f1815ab Use 'printf %s $x' notation in t5401
We only care about getting what should be an empty string and
sending it to a file, without a trailing LF, so the empty string
translates into a 0 byte file.  Earlier when I originally wrote
these lines Mac OS X allowed the format string of printf to be
the empty string, but more recent versions appear to have been
'improved' with error messages if the format is not given.

This may cause problems if we ever wind up with changes to the hook
tests.  A minor cleanup makes the test more safe on all systems,
by conforming to accepted printf conventions.

3a9f0f41db parse-options: catch likely typo in presense of aggregated options.
If options are aggregated, and that the whole token is an exact
prefix of a long option that is longer than 2 letters, reject
it.  This is to prevent a common typo:

	$ git commit -amend

to get interpreted as "commit all with message 'end'".

The typo check isn't performed if there is no aggregation,
because the stuck form is the recommended one.  If we have `-o`
being a valid short option that takes an argument, and --option
a long one, then we _MUST_ accept -option as "'o' option with
argument 'ption'", which is our official recommended form.

7fec10b7f4 index: be careful when handling long names
We currently use lower 12-bit (masked with CE_NAMEMASK) in the
ce_flags field to store the length of the name in cache_entry,
without checking the length parameter given to
create_ce_flags().  This can make us store incorrect length.

Currently we are mostly protected by the fact that many
codepaths first copy the path in a variable of size PATH_MAX,
which typically is 4096 that happens to match the limit, but
that feels like a bug waiting to happen.  Besides, that would
not allow us to shorten the width of CE_NAMEMASK to use the bits
for new flags.

This redefines the meaning of the name length stored in the
cache_entry.  A name that does not fit is represented by storing
CE_NAMEMASK in the field, and the actual length needs to be
computed by actually counting the bytes in the name[] field.
This way, only the unusually long paths need to suffer.
