2ad23273e7 do not use GIT_TRACE_PACKET=3 in tests
Some test scripts use the GIT_TRACE mechanism to dump
debugging information to descriptor 3 (and point it to a
file using the shell). On Windows, however, bash is unable
to set up descriptor 3. We do not write our trace to the
file, and worse, we may interfere with other operations
happening on descriptor 3, causing tests to fail or even
behave inconsistently.

Prior to commit 97a83fa (upload-pack: remove packet debugging
harness), these tests used GIT_DEBUG_SEND_PACK, which only
supported output to a descriptor. The tests in t5503 were
always broken on Windows, and were marked to be skipped via
the NOT_MINGW prerequisite. In t5700, the tests used to pass
prior to 97a83fa, but only because they were not careful
enough; because we only grepped the trace file, an empty
file looked successful to us. But post-97a83fa, the writing
to descriptor 3 causes "git fetch" to hang (presumably
because we are throwing random bytes into the middle of the
protocol).

Now that we are using the GIT_TRACE mechanism, we can
improve both scripts by asking git to write directly to a
file rather than a descriptor. That fixes the hang in t5700,
and should allow t5503 to successfully run on Windows.

In both cases we now also use "test -s" to double-check that
our trace file actually contains output, which should reduce
the possibility of an erroneously passing test.

848575d833 push test: simplify check of push result
This test checks each ref with code like the following:

	r=$(git show-ref -s --verify refs/$ref) &&
	test "z$r" = "z$the_first_commit"

Afterward it counts refs:

	test 1 = $(git for-each-ref refs/remotes/origin | wc -l)

Simpler to test the number and values of relevant refs in for-each-ref
output at the same time using test_cmp.  This makes the test more
readable and provides more helpful "./t5516-push-push.sh -v" output
when the test fails.

c29c46fa2e pack-refs: add fully-peeled trait
Older versions of pack-refs did not write peel lines for
refs outside of refs/tags. This meant that on reading the
pack-refs file, we might set the REF_KNOWS_PEELED flag for
such a ref, even though we do not know anything about its
peeled value.

The previous commit updated the writer to always peel, no
matter what the ref is. That means that packed-refs files
written by newer versions of git are fine to be read by both
old and new versions of git. However, we still have the
problem of reading packed-refs files written by older
versions of git, or by other implementations which have not
yet learned the same trick.

The simplest fix would be to always unset the
REF_KNOWS_PEELED flag for refs outside of refs/tags that do
not have a peel line (if it has a peel line, we know it is
valid, but we cannot assume a missing peel line means
anything). But that loses an important optimization, as
upload-pack should not need to load the object pointed to by
refs/heads/foo to determine that it is not a tag.

Instead, we add a "fully-peeled" trait to the packed-refs
file. If it is set, we know that we can trust a missing peel
line to mean that a ref cannot be peeled. Otherwise, we fall
back to assuming nothing.

03a8eddfd1 pack-refs: write peeled entry for non-tags
When we pack an annotated tag ref, we write not only the
sha1 of the tag object along with the ref, but also the sha1
obtained by peeling the tag. This lets readers of the
pack-refs file know the peeled value without having to
actually load the object, speeding up upload-pack's ref
advertisement.

The writer marks a packed-refs file with peeled refs using
the "peeled" trait at the top of the file. When the reader
sees this trait, it knows that each ref is either followed
by its peeled value, or it is not an annotated tag.

However, there is a mismatch between the assumptions of the
reader and writer. The writer will only peel refs under
refs/tags, but the reader does not know this; it will assume
a ref without a peeled value must not be a tag object. Thus
an annotated tag object placed outside of the refs/tags
hierarchy will not have its peeled value printed by
upload-pack.

The simplest way to fix this is to start writing peel values
for all refs. This matches what the reader expects for both
new and old versions of git.

06f15bf1f3 upload-pack: make sure "want" objects are parsed
When upload-pack receives a "want" line from the client, it
adds it to an object array. We call lookup_object to find
the actual object, which will only check for objects already
in memory. This works because we are expecting to find
objects that we already loaded during the ref advertisement.

We use the resulting object structs for a variety of
purposes. Some of them care only about the object flags, but
others care about the type of the object (e.g.,
ok_to_give_up), or even feed them to the revision parser
(when --depth is used), which assumes that objects it
receives are fully parsed.

Once upon a time, this was OK; any object we loaded into
memory would also have been parsed. But since 435c833
(upload-pack: use peel_ref for ref advertisements,
2012-10-04), we try to avoid parsing objects during the ref
advertisement. This means that lookup_object may return an
object with a type of OBJ_NONE. The resulting mess depends
on the exact set of objects, but can include the revision
parser barfing, or the shallow code sending the wrong set of
objects.

This patch teaches upload-pack to parse each "want" object
as we receive it. We do not replace the lookup_object call
with parse_object, as the current code is careful not to let
just any object appear on a "want" line, but rather only one
we have previously advertised (whereas parse_object would
actually load any arbitrary object from disk).

b397ea4863 status: show more info than "currently not on any branch"
When a remote ref or a tag is checked out, HEAD is automatically
detached. There is no user-friendly way to find out what ref is
checked out in this case. This patch digs in reflog for this
information and shows "HEAD detached from origin/master" or "HEAD
detached at v1.8.0" instead of "currently not on any branch".

When it cannot figure out the original ref, it shows an abbreviated
SHA-1. "Currently not on any branch" would never display (unless
reflog is pruned to near empty that the last checkout entry is lost).

7297a44012 entry: fix filter lookup
When looking up the stream filter, write_entry() should be passing the
path of the file in the repository, not the path to which the content is
going to be written.  This allows the file to be correctly looked up
against the .gitattributes files in the working tree.

This change makes the streaming case match the non-streaming case which
passes ce->name to convert_to_working_tree later in the same function.

The two tests added here test the different paths through write_entry
since the CRLF filter is a streaming filter but the user-defined smudge
filter is not streamed.

fa04ae0be8 Allow combined diff to ignore white-spaces
The combined diff --cc output does not honor options to ignore
whitespace changes (-b, -w, and --ignore-space-at-eol).

Correct this by passing diff flags to diff engine, so that combined
diff behaves as normal diff does with spaces, and by coalescing
lines that are removed from both (or more) parents, honoring the
same rule to ignore whitespace changes.

With this change, a conflict-less merge done using a ignore-*
strategy option will not show any conflict if shown in combined-diff
using the same option.

02c56314aa difftool --dir-diff: symlink all files matching the working tree
Some users like to edit files in their diff tool when using "git
difftool --dir-diff --symlink" to compare against the working tree but
difftool currently only created symlinks when a file contains unstaged
changes.

Change this behaviour so that symlinks are created whenever the
right-hand side of the comparison has the same SHA1 as the file in the
working tree.

Note that textconv filters are handled in the same way as by git-diff
and if a clean filter is not the inverse of its smudge filter we already
get a null SHA1 from "diff --raw" and will symlink the file without
going through the new hash-object based check.

bbd848633e git p4: avoid expanding client paths in chdir
The generic chdir() helper sets the PWD environment
variable, as that is what is used by p4 to know its
current working directory.  Normally the shell would
do this, but in git-p4, we must do it by hand.

However, when the path contains a symbolic link,
os.getcwd() will return the physical location.  If the
p4 client specification includes symlinks, setting PWD
to the physical location causes p4 to think it is not
inside the client workspace.  It complains, e.g.

    Path /vol/bar/projects/foo/... is not under client root /p/foo

One workaround is to use AltRoots in the p4 client specification,
but it is cleaner to handle it directly in git-p4.

Other uses of chdir still require setting PWD to an
absolute path so p4 features like P4CONFIG work.  See
bf1d68f (git-p4: use absolute directory for PWD env
var, 2011-12-09).

bd54cf17a4 archive: handle commits with an empty tree
git-archive relies on get_pathspec to convert its argv into
a list of pathspecs. When get_pathspec is given an empty
argv list, it returns a single pathspec, the empty string,
to indicate that everything matches. When we feed this to
our path_exists function, we typically see that the pathspec
turns up at least one item in the tree, and we are happy.

But when our tree is empty, we erroneously think it is
because the pathspec is too limited, when in fact it is
simply that there is nothing to be found in the tree. This
is a weird corner case, but the correct behavior is almost
certainly to produce an empty archive, not to exit with an
error.

This patch teaches git-archive to create empty archives when
there is no pathspec given (we continue to complain if a
pathspec is given, since it obviously is not matched). It
also confirms that the tar and zip writers produce sane
output in this instance.

6cd3c05327 format-patch: RFC 2047 says multi-octet character may not be split
Even though an earlier attempt (bafc478..41dd00bad) cleaned
up RFC 2047 encoding, pretty.c::add_rfc2047() still decides
where to split the output line by going through the input
one byte at a time, and potentially splits a character in
the middle.  A subject line may end up showing like this:

     ".... fö?? bar".   (instead of  ".... föö bar".)

if split incorrectly.

RFC 2047, section 5 (3) explicitly forbids such beaviour

    Each 'encoded-word' MUST represent an integral number of
    characters.  A multi-octet character may not be split across
    adjacent 'encoded- word's.

that means that e.g. for

    Subject: .... föö bar

encoding

    Subject: =?UTF-8?q?....=20f=C3=B6=C3=B6?=
     =?UTF-8?q?=20bar?=

is correct, and

    Subject: =?UTF-8?q?....=20f=C3=B6=C3?=      <-- NOTE ö is broken here
     =?UTF-8?q?=B6=20bar?=

is not, because "ö" character UTF-8 encoding C3 B6 is split here across
adjacent encoded words.

To fix the problem, make the loop grab one _character_ at a time and
determine its output length to see where to break the output line.  Note
that this version only knows about UTF-8, but the logic to grab one
character is abstracted out in mbs_chrlen() function to make it possible
to extend it to other encodings with the help of iconv in the future.

45c45e300b git add: start preparing for "git add <pathspec>..." to default to "-A"
When "git add subdir/" is run without "-u" or "-A" option, e.g.

    $ edit subdir/x
    $ create subdir/y
    $ rm subdir/z
    $ git add subdir/

the command does not notice removal of paths (e.g. subdir/z) from
the working tree.  This sometimes confuses new people, as arguably
"git add" is told to record the current state of "subdir/" as a
whole, not the current state of the paths that exist in the working
tree that matches that pathspec (the latter by definition excludes
the state of "subdir/z" because it does not exist in the working
tree).

Plan to eventually make "git add" pretend as if "-A" is given when
there is a pathspec on the command line.  When resolving a conflict
to remove a path, the current code tells you to "git rm $path", but
with such a change, you will be able to say "git add $path" (of
course you can do "git add -A $path" today).  That means that we can
simplify the advice messages given by "git status".  That all will
be in Git 2.0 or later, if we are going to do so.

For that transition to work, people need to learn either to say "git
add --no-all subdir/" when they want to ignore the removed paths
like "subdir/z", or to say "git add -A subdir/" when they want to
take the state of the directory as a whole.

"git add" without any argument will continue to be a no-op.

2cd83d10bb setup: suppress implicit "." work-tree for bare repos
If an explicit GIT_DIR is given without a working tree, we
implicitly assume that the current working directory should
be used as the working tree. E.g.,:

  GIT_DIR=/some/repo.git git status

would compare against the cwd.

Unfortunately, we fool this rule for sub-invocations of git
by setting GIT_DIR internally ourselves. For example:

  git init foo
  cd foo/.git
  git status ;# fails, as we expect
  git config alias.st status
  git status ;# does not fail, but should

What happens is that we run setup_git_directory when doing
alias lookup (since we need to see the config), set GIT_DIR
as a result, and then leave GIT_WORK_TREE blank (because we
do not have one). Then when we actually run the status
command, we do setup_git_directory again, which sees our
explicit GIT_DIR and uses the cwd as an implicit worktree.

It's tempting to argue that we should be suppressing that
second invocation of setup_git_directory, as it could use
the values we already found in memory. However, the problem
still exists for sub-processes (e.g., if "git status" were
an external command).

You can see another example with the "--bare" option, which
sets GIT_DIR explicitly. For example:

  git init foo
  cd foo/.git
  git status ;# fails
  git --bare status ;# does NOT fail

We need some way of telling sub-processes "even though
GIT_DIR is set, do not use cwd as an implicit working tree".
We could do it by putting a special token into
GIT_WORK_TREE, but the obvious choice (an empty string) has
some portability problems.

Instead, we add a new boolean variable, GIT_IMPLICIT_WORK_TREE,
which suppresses the use of cwd as a working tree when
GIT_DIR is set. We trigger the new variable when we know we
are in a bare setting.

The variable is left intentionally undocumented, as this is
an internal detail (for now, anyway). If somebody comes up
with a good alternate use for it, and once we are confident
we have shaken any bugs out of it, we can consider promoting
it further.

9e7b8efb9d git p4 test: make sure P4CONFIG relative path works
This adds a test for the fix in bf1d68f (git-p4: use absolute
directory for PWD env var, 2011-12-09).  It is necessary to
set PWD to an absolute path so that p4 can find files referenced
by non-absolute paths, like the value of the P4CONFIG environment
variable.

P4 does not open files directly; it builds a path by prepending
the contents of the PWD environment variable.

c2aba155da push: --follow-tags
The new option "--follow-tags" tells "git push" to push annotated
tags that are missing from the other side and that can be reached by
the history that is otherwise pushed out.

For example, if you are using the "simple", "current", or "upstream"
push, you would ordinarily push the history leading to the commit at
your current HEAD and nothing else.  With this option, you would
also push all annotated tags that can be reached from that commit to
the other side.

cf41982806 submodule: add 'deinit' command
With "git submodule init" the user is able to tell git he cares about one
or more submodules and wants to have it populated on the next call to "git
submodule update". But currently there is no easy way he could tell git he
does not care about a submodule anymore and wants to get rid of his local
work tree (except he knows a lot about submodule internals and removes the
"submodule.$name.url" setting from .git/config together with the work tree
himself).

Help those users by providing a 'deinit' command. This removes the
whole submodule.<name> section from .git/config (either for the given
submodule(s) or for all those which have been initialized if '.' is used)
together with their work tree. Fail if the current work tree contains
modifications (unless forced), but don't complain when either the work
tree is already removed or no settings are found in .git/config.

Add tests and link the man pages of "git submodule deinit" and "git rm"
to assist the user in deciding whether removing or unregistering the
submodule is the right thing to do for him. Also add the deinit subcommand
to the completion list.

8b1bd02415 Make !pattern in .gitattributes non-fatal
Before 82dce99 (attr: more matching optimizations from .gitignore,
2012-10-15), .gitattributes did not have any special treatment of a
leading '!'.  The docs, however, always said

  The rules how the pattern matches paths are the same as in
  `.gitignore` files; see linkgit:gitignore[5].

By those rules, leading '!' means pattern negation.  So 82dce99
correctly determined that this kind of line makes no sense and should
be disallowed.

However, users who actually had a rule for files starting with a '!'
are in a bad position: before 82dce99 '!' matched that literal
character, so it is conceivable that users have .gitattributes with
such lines in them.  After 82dce99 the unescaped version was
disallowed in such a way that git outright refuses to run(!) most
commands in the presence of such a .gitattributes.  It therefore
becomes very hard to fix, let alone work with, such repositories.

Let's at least allow the users to fix their repos: change the fatal
error into a warning.

2092678cd5 name-hash.c: fix endless loop with core.ignorecase=true
With core.ignorecase=true, name-hash.c builds a case insensitive index of
all tracked directories. Currently, the existing cache entry structures are
added multiple times to the same hashtable (with different name lengths and
hash codes). However, there's only one dir_next pointer, which gets
completely messed up in case of hash collisions. In the worst case, this
causes an endless loop if ce == ce->dir_next (see t7062).

Use a separate hashtable and separate structures for the directory index
so that each directory entry has its own next pointer. Use reference
counting to track which directory entry contains files.

There are only slight changes to the name-hash.c API:
- new free_name_hash() used by read_cache.c::discard_index()
- remove_name_hash() takes an additional index_state parameter
- index_name_exists() for a directory (trailing '/') may return a cache
  entry that has been removed (CE_UNHASHED). This is not a problem as the
  return value is only used to check if the directory exists (dir.c) or to
  normalize casing of directory names (read-cache.c).

Getting rid of cache_entry.dir_next reduces memory consumption, especially
with core.ignorecase=false (which doesn't use that member at all).

With core.ignorecase=true, building the directory index is slightly faster
as we add / check the parent directory first (instead of going through all
directory levels for each file in the index). E.g. with WebKit (~200k
files, ~7k dirs), time spent in lazy_init_name_hash is reduced from 176ms
to 130ms.

d3c1472fe3 archive-zip: fix compressed size for stored export-subst files
Currently ZIP archive entries of files with export-subst attribute are
broken if they are stored uncompressed.

We get the size of a file from sha1_object_info(), but this number is
likely wrong for files whose contents are changed due to export-subst
placeholder expansion.  We use sha1_file_to_archive() to get the
expanded file contents and size in that case.  We proceed to use that
size for the uncompressed size field (good), but the compressed size
field is set based on the size from sha1_object_info() (bad).

This matters only for uncompressed files because for deflated files
we use the correct value after compression is done.  And for files
without export-subst expansion the sizes from sha1_object_info() and
sha1_file_to_archive() are the same, so they are unaffected as well.

This patch fixes the issue by setting the compressed size based on the
uncompressed size only after we actually know the latter.

Also make use of the test file substfile1 to check for the breakage;
it was only stored verbatim so far.  For that purpose, set the
attribute export-subst and replace its contents with the expected
expansion after committing.
