057e71384a Warn use of "origin" when remotes/origin/HEAD is dangling
The previous one squelched the diagnositic message we used to issue every
time we enumerated the refs and noticed a dangling ref.  This adds the
warning back to the place where the user actually attempts to use it.

f8948e2fbc remote prune: warn dangling symrefs
If you prune from the remote "frotz" that deleted the ref your tracking
branch remotes/frotz/HEAD points at, the symbolic ref will become
dangling.  We used to detect this as an error condition and issued a
message every time refs are enumerated.

This stops the error message, but moves the warning to "remote prune".

8ea7ad694b Fix the installation path for html documentation
026fa0d (Move computation of absolute paths from Makefile to runtime in
preparation for RUNTIME_PREFIX, 2009-01-18) broke the installation of html
documentation.  A relative htmldir is given to Documentation/Makefile and
html documentations are installed in a subdirectory of "Documentation" in
the source tree.

Fix this by not exporting htmldir from Makefile; this allows
Documentation/Makefile to compute the htmldir from the prefix.

75f3ff2eea Generalize and libify index_is_dirty() to index_differs_from(...)
index_is_dirty() in builtin-revert.c checks if the index is dirty.
This patch generalizes this function to check if the index differs
from a revision, i.e. the former index_is_dirty() behavior can now be
achieved by index_differs_from("HEAD", 0).

The second argument "diff_flags" allows to set further diff option
flags like DIFF_OPT_IGNORE_SUBMODULES. See DIFF_OPT_* macros in diff.h
for a list.

index_differs_from() seems to be useful for more than builtin-revert.c,
so it is moved into diff-lib.c and also used in builtin-commit.c.

Yet to mention:

 - "rev.abbrev = 0;" can be safely removed.
   This has no impact on performance or functioning of neither
   setup_revisions() nor run_diff_index().

 - rev.pending.objects is free()d because this fixes a leak.
   (Also see 295dd2ad "Fix memory leak in traverse_commit_list")

2f33415563 Modernize t5400 test script
Many tests checked for failure by hand without using test_must_fail (they
probably predate the shell function).

When we know the desired outcome, explicitly check for it, instead of
checking if the result does not match one possible incorrect outcome.
E.g. if you expect a push to be refused, you do not test if the result is
different from what was pushed.  Instead, make sure that the ref did not
before and after the push.

The test sequence chdir'ed around and any failure at one point could have
started the next test in an unexpected directory.  Fix this problem by
using subshells as necessary.

7734f04873 lstat_cache(): print a warning if doing ping-pong between cache types
This is a debug patch which is only to be used while the lstat_cache()
is in the test stage, and should be removed/reverted before the final
relase.

I think it should be useful to catch these warnings, as I it could be
an indication of that the cache would not be very effective if it is
doing ping-pong by switching between different cache types too many
times.

Also, if someone is experimenting with the lstat_cache(), this patch
will maybe be useful while debugging.

If someone is able to trigger the warning, then send a mail to the GIT
mailing list, containing the first 15 lines of the warning, and a
short description of the GIT commands to trigger the warnings.

I hope someone is willing to use this patch for a while, to be able to
catch possible ping-pong's.

7847892716 unlink_entry(): introduce schedule_dir_for_removal()
Currently inside unlink_entry() if we get a successful removal of one
file with unlink(), we try to remove the leading directories each and
every time.  So if one directory containing 200 files is moved to an
other location we get 199 failed calls to rmdir() and 1 successful
call.

To fix this and avoid some unnecessary calls to rmdir(), we schedule
each directory for removal and wait much longer before we do the real
call to rmdir().

Since the unlink_entry() function is called with alphabetically sorted
names, this new function end up being very effective to avoid
unnecessary calls to rmdir().  In some cases over 95% of all calls to
rmdir() is removed with this patch.

60b458b7d3 lstat_cache(): small cleanup and optimisation
Simplify the if-else test in longest_match_lstat_cache() such that we
only have one simple if test.  Instead of testing for 'i == cache.len'
or 'i == len', we transform this to a common test for 'i == max_len'.

And to further optimise we use 'i >= max_len' instead of 'i ==
max_len', the reason is that it is now the exact opposite of one part
inside the while-loop termination expression 'i < max_len && name[i]
== cache.path[i]', and then the compiler can probably reuse a test
instruction from it.

We also throw away the arguments to reset_lstat_cache(), such that all
the safeguard logic inside lstat_cache() is handled at one place.

9aad6cbaef add -p: get rid of Git.pm warnings about unitialized values
After invoking git add -p I always got the warnings:

 Use of uninitialized value $_[3] in exec at Git.pm line 1282.
 Use of uninitialized value $args[2] in join or string at Git.pm line 1264.

A bisect showed that these warnings occur in a301973 "add -p: print errors
in separate color" the first time.

They can be reproduced by setting color.ui (or color.interactive) to "auto"
and unsetting color.interactive.help and color.interactive.error.
I am using Perl 5.10.0.

The reason of the warning is that color.interactive.error defaults to
color.interactive.help which defaults to nothing in the specific codepath.
It defaults to 'red bold' some lines above which could lead to the wrong
assumption that it always defaults to 'red bold' now.

This patch lets it default to 'red bold', blowing the warnings away.

f42302b493 Test and fix normalize_path_copy()
This changes the test-path-utils utility to invoke normalize_path_copy()
instead of normalize_absolute_path() because the latter is about to be
removed.

The test cases in t0060 are adjusted in two regards:

- normalize_path_copy() more often leaves a trailing slash in the result.
  This has no negative side effects because the new user of this function,
  longest_ancester_length(), already accounts for this behavior.

- The function can fail.

The tests uncover a flaw in normalize_path_copy(): If there are
sufficiently many '..' path components so that the root is reached, such as
in "/d1/s1/../../d2", then the leading slash was lost. This manifested
itself that (assuming there is a repository at /tmp/foo)

  $ git add /d1/../tmp/foo/some-file

reported 'pathspec is outside repository'. This is now fixed.

Moreover, the test case descriptions of t0060 now include the test data and
expected outcome.

43a7ddb55d Fix GIT_CEILING_DIRECTORIES on Windows
Using git with GIT_CEILING_DIRECTORIES crashed on Windows due to a failed
assertion in normalize_absolute_path(): This function expects absolute
paths to start with a slash, while on Windows they can start with a drive
letter or a backslash.

This fixes it by using the alternative, normalize_path_copy() instead,
which can handle Windows-style paths just fine.

Secondly, the portability macro PATH_SEP is used instead of expecting
colons to be used as path list delimiter.

The test script t1504 is also changed to help MSYS's bash recognize some
program arguments as path list. (MSYS's bash must translate POSIX-style
path lists to Windows-style path lists, and the heuristic did not catch
some cases.)

2cd85c40a9 Make test-path-utils more robust against incorrect use
Previously, this test utility happily returned with exit code 0 if garbage
was thrown at it. Now it reports failure if an unknown function name was
given on the command line.

d3bee161fe tree.c: allow read_tree_recursive() to traverse gitlink entries
When the callback function invoked from read_tree_recursive() returns
the value `READ_TREE_RECURSIVE` for a gitlink entry, the traversal will
now continue into the tree connected to the gitlinked commit. This
functionality can be used to allow inter-repository operations, but
since the current users of read_tree_recursive() does not yet support
such operations, they have been modified where necessary to make sure
that they never return READ_TREE_RECURSIVE for gitlink entries (hence
no change in behaviour should be introduces by this patch alone).
